SHUTTLE ATLANTIS CREW RETURNS HOME AFTER SUCCESSFUL MISSION

The space shuttle Atlantis and its crew are home after completing a 14-day journey of more than 5.8 million miles in space. Atlantis' STS-117 mission successfully increased the power capability of the International Space Station, preparing for the future delivery of European and Japanese laboratories.

Atlantis' Commander Rick Sturckow, Pilot Lee Archambault and mission specialists Jim Reilly, Patrick Forrester, Steven Swanson, John "Danny" Olivas and Sunita Williams landed at Edwards Air Force Base, Calif., Friday at 3:49 p.m. EDT.


Atlantis' crew attached the new S3/S4 solar array truss segment on the right side of the station's backbone, deployed a new set of solar arrays, and retracted the Port 6 starboard solar array back into its box. The station has a new look with two symmetrical solar panels mounted on each end of the station's truss.

Reilly, Olivas, Swanson and Forrester, with the help of crewmates, made four spacewalks to complete the construction tasks. They activated the truss segment and the Solar Alpha Rotary Joint, which allows the new arrays to track the sun, and helped fold the Port 6 array. During the third spacewalk, the crew repaired a 4-by-6 inch raised corner of a thermal blanket on the port side Orbital Maneuvering System pod. Aerodynamic forces during Atlantis' ascent lifted the blanket.

While the crew worked in space, ground teams were troubleshooting a problem with Russian computers that help control the station's attitude. Russian specialists worked closely with teams in the United States to recover the computer capabilities.

NASA astronaut and station Flight Engineer Clayton Anderson, who launched with the crew aboard Atlantis, remained on the station. He is scheduled to return home aboard space shuttle Discovery on a mission targeted for launch in October. Anderson replaced Williams, who set a new record for a single, long-duration spaceflight by a
woman with 195 days. She arrived at the station in December 2006 aboard space shuttle Discovery.

STS-117 was the 118th space shuttle flight, the 21st flight to the station, the 28th flight for Atlantis and the first of four missions planned for 2007.

Several inspections in orbit revealed no critical damage, and Atlantis' thermal protection system was declared safe for re-entry on flight day 13. Weather concerns prevented the crew from returning to NASA's Kennedy Space Center, Fla., the primary end-of-mission landing site. In 7-10 days, Atlantis will be transported approximately 2,500 miles from California to Florida on the back of a modified 747 jumbo jet. Once at Kennedy, Atlantis will be separated from the aircraft to
begin immediate processing for its next flight, targeted for December
2007.

With Atlantis and its crew safely home, the stage is set for the next phase of International Space Station assembly. Preparations continue for space shuttle Endeavour's launch, targeted for August, on the STS-118 mission to deliver the S5 truss segment to the station.

Bad Weather Pushes STS-117 Landing to Friday

The STS-117 crew is getting an extra day in space thanks to poor weather conditions at Kennedy Space Center, Fla. Space shuttle Atlantis has five landing opportunities available Friday, with the first at 2:18 p.m. EDT in Florida.

Thunderstorms in the vicinity of Kennedy forced flight controllers to wave off both opportunities Thursday. Controllers and the Spaceflight Meteorology Group will closely monitor forecasts for Friday’s opportunities in Florida and at Edwards Air Force Base in California.

The first opportunity Friday is on Orbit 218 and calls for a deorbit burn at 1:12 p.m. The second is on Orbit 219, with the deorbit burn at 2:50 p.m. and landing at 3:55 p.m. at Kennedy.

If Florida weather does not cooperate, three opportunities are available at Edwards. The first is on Orbit 219. Thursday afternoon, the crew adjusted Atlantis’ orbit to set the stage for this opportunity, which has the deorbit burn occurring at 2:43 p.m. and landing at 3:49 p.m.

The second opportunity for the California base is on Orbit 220. The deorbit burn would occur at 4:18 p.m. and landing at 5:23 p.m. The final opportunity is one orbit later which calls for the deorbit burn to occur at 5:56 p.m. and landing at 6:59 p.m.

Friday’s weather forecast for Kennedy calls for the threat of thunderstorms in the area and high winds are a possibility at Edwards. Opportunities are also available Saturday.

Atlantis launched June 8 and arrived at the International Space Station on June 10. While at the orbital outpost, the crew installed the Starboard 3 and 4 truss segment and conducted four spacewalks to activate it. During the third spacewalk, the crew repaired an out of position thermal blanket on the left orbital maneuvering system pod.

Atlantis also delivered a new station crew member, Flight Engineer Clayton Anderson. He replaced astronaut Suni Williams, who is the new record holder for a long-duration single spaceflight for a woman. She arrived at the station in December with STS-116.

STS-117 is the 118th shuttle mission and 21st mission to visit the space station. The next mission, STS-118, is slated to launch in August.

Shuttle Astronauts Prepare for Return to Earth

During its scheduled final full day in space, the STS-117 crew prepared for landing. Two opportunities are available on Thursday for Space Shuttle Atlantis to land at Kennedy Space Center, Fla.

Wednesday’s preparations included stowing equipment and checking out systems that will be used to deorbit Atlantis and begin the descent to Earth. Also, the seven crew members took time out of their schedules to talk with reporters from NBC News, ABC News and CNN Live.


The first landing opportunity available is on Orbit 202, which calls for the deorbit burn to occur 12:50 p.m. EDT Thursday with a 1:55 p.m. touchdown. The final opportunity of the day is on the next orbit. It begins with the deorbit burn at 2:25 p.m. and ends with a 3:30 p.m. landing.

Weather forecasts call for a possibility of thunder showers in the area. Flight controllers and forecasters with the Spaceflight Meteorology Group will continue to monitor the weather at Kennedy.

The STS-117 crew members are returning home from a construction mission to the International Space Station. They installed the Starboard 3 and 4 (S3/S4) truss segment and conducted four spacewalks to activate it.

During the third spacewalk, the crew repaired an out of position thermal blanket on the left orbital maneuvering system pod.

Atlantis also delivered a new station crew member, Flight Engineer Clayton Anderson. He replaced astronaut Suni Williams, who is the new record holder for a long-duration single spaceflight for a woman. She arrived at the station in December with STS-116.

Atlantis Leaves Station, Begins Journey Home

The STS-117 crew members ended their stay at the International Space Station Tuesday when they undocked Space Shuttle Atlantis at 10:42 a.m. EDT. Attention now turns to landing, scheduled for 1:54 p.m. Thursday.

The STS-117 crew members ended their stay at the International Space Station Tuesday when they undocked Space Shuttle Atlantis at 10:42 a.m. EDT. Attention now turns to landing, scheduled for 1:54 p.m. Thursday.

Following undocking, Pilot Lee Archambault flew Atlantis 360 degrees around the station to collect video and imagery of the station and its newly expanded solar wings. He then completed the final separation engine burn at 12:28 p.m.

Later in the day, Archambault and Mission Specialists Patrick Forrester and Steven Swanson used the shuttle robot arm and the 50-foot long Orbiter Boom Sensor System to conduct a late inspection of the thermal protection system.

The crew will spend Wednesday preparing for landing. Atlantis’ first landing opportunity is at 1:54 p.m. Thursday at Kennedy Space Center, Fla.

During its stay at the station, which began June 10, the STS-117 crew continued the on-orbit construction of the station with the installation of the Starboard 3 and 4 (S3/S4) truss segment.

The crew installed the truss June 11 and conducted four spacewalks to activate the S3/S4 and assist in the retraction of solar array on the Port 6 truss. During the third spacewalk, the crew repaired an out of position thermal blanket on the left orbital maneuvering system pod.

Atlantis also delivered a new station crew member, Flight Engineer Clayton Anderson. He replaced astronaut Suni Williams, who is the new record holder for a long-duration single spaceflight for a woman. She arrived at the station in December with STS-116.

STS-117 Astronauts Conclude Fourth Spacewalk

STS-117’s final spacewalk came to an end Sunday at 6:54 p.m. EDT. During the 6-hour, 29-minute orbital stroll, Mission Specialists Patrick Forrester and Steven Swanson performed tasks to activate the International Space Station’s new truss segment and completed work that will help future spacewalkers.

Forrester and Swanson began the excursion at 12:25 p.m. and quickly went to work preparing the Starboard 3 and 4 (S3/S4) truss segment for operation. The S3/S4 was installed onto the station on June 11. Most of the S3/S4 work centered on activating the Solar Alpha Rotary Joint (SARJ), which will allow the S3/S4 arrays to track the Sun.


Early in the spacewalk, Forrester verified the installation of the Drive Lock Assembly 2, one of two mechanisms that will drive rotation of the SARJ, while Swanson installed a TV camera and its support structure. Then, the duo removed the final launch restraints on the SARJ before removing a keel pin and drag link to clear the path for the station’s mobile transporter.

The get-ahead tasks included the installation of a computer network cable onto the Unity module and the removal of a Global Positioning System antenna. The two astronauts also finished the installation of a piece of debris shielding on the Destiny laboratory.

Mission Specialist Jim Reilly coordinated the spacewalk and Pilot Lee Archambault operated the robot arm. Forrester and Swanson conducted STS-117’s second spacewalk. Reilly and Mission Specialist Danny Olivas conducted the other two. Sunday’s spacewalk is the 87th devoted to station assembly and maintenance.

Attention now turns to Atlantis' departure and the events leading up to undocking. The STS-117 crew is scheduled to exit the station Monday before the hatches close at 6:23 p.m. EDT. Atlantis is slated to undock at 10:42 a.m. Tuesday.

However, mission managers may decide to add a day of docked operations for STS-117 if the Russian navigation computers do not perform adequately during a test of Russian attitude control capabilities Monday morning at 10:28 a.m.

Russian Navigation Computers in Stable Condition

The Russian computers aboard the International Space Station are back in near normal, stable operation. Two of three channels of each computer are operating. A third channel is believed to be functioning well, but currently in standby.

The Mission Control Center in Moscow has restarted all Russian systems except the Elektron oxygen generation system, which has been powered but not yet started.

Flight controllers are planning to test Russian thrusters on Monday as they maneuver the station and Space Shuttle Atlantis to a water dump attitude.

The Russian navigation computers provide one method of backup attitude control and orbital altitude adjustments. The station’s control moment gyroscopes are the complex’s primary attitude control system. The shuttle’s propulsion system also provides a backup attitude control system for the complex.

Astronaut Suni Williams Sets the Record Straight, and Long

Call it a great leap forward for women in space.

After six years of people, three of whom have been women, living in space aboard the International Space Station, the female time-in-space endurance record set 11 years ago has been broken.


NASA Astronaut Sunita Williams set a new record this morning at 12:47 CDT for the longest duration spaceflight by a woman. At that time, Williams surpassed Shannon Lucid’s mark of 188 days, 4 hours set in 1996.

Williams began her record-setting flight when she launched with the crew of STS-116 in December 2006. The Massachusetts native remained onboard the station as a member of the Expedition 14 crew and then joined the Expedition 15 crew in April. Her spaceflight will come to a close when she returns to Earth aboard Space Shuttle Atlantis with the STS-117 crew.

Although this is only her first spaceflight, Williams also became the record-holder for most hours outside a spacecraft by a female by completing four spacewalks during Expedition 15 with a total time of 29 hours, 17 minutes.

“It was very exciting to watch her spacewalks and to watch her accumulate more spacewalk time than any other female in the universe,” said Lucid, who set the previous female space duration record while flying aboard the Russian Mir Space Station. “These [long-term] flights are providing the needed confidence so that some day in the near future we can depart low-Earth orbit and head on out to Mars.”

During her stay on orbit, Williams has worked with experiments across a wide variety of fields, including human life sciences, physical sciences and Earth observation as well as education and technology demonstrations.

Some of these experiments give scientists critical insight into the effects of weightlessness on our bodies while others show ways to prevent effects we already know about like muscle and bone loss.

In addition to rigorous exercise, Williams also collected and stored her blood while in space to add to an ongoing study on nutrition, another key element of living in space for long stretches of time.

The results of this study may impact nutritional requirements and food systems developed for future ventures in space. “Her mission has been critically important to our overall space program,” said NASA Astronaut Eileen Collins, another female pioneer in spaceflight. Collins became the first woman to command a spaceflight mission during the STS-93 mission on Space Shuttle Columbia.

“She truly is a space marathoner who shows young women everywhere that there's a place in the space program for them.” If her stay in space concludes as scheduled, with her return on Atlantis on June 21, Williams will have flown a total of 194 days in space.

Astronauts Fold Arrays, Prepare for Spacewalk

The STS-117 and Expedition 15 crews moved through a busy day aboard the International Space Station and Space Shuttle Atlantis. They were retracting solar arrays and preparing for STS-117’s third spacewalk.


The STS-117 crew resumed retraction of the starboard P6 solar array at 12:25 p.m. Thursday. The crew and flight controllers decided to conclude the efforts just before 4 p.m. with about half of the 31½ array bays retracted. The crew will resume retraction activities Friday with the help of the spacewalkers if needed.

The schedule for STS-117 Mission Specialists Jim Reilly and Danny Olivas includes a review of procedures and the practice of techniques they will use during the spacewalk set to begin at 1:38 p.m. EDT Friday. The first task of the extravehicular activity is the repair of a thermal blanket that pulled away from the orbital maneuvering system pod on the rear of the shuttle.

About an hour and 20 minutes before Thursday morning’s scheduled wakeup call, the crews were awakened by a false alarm on the station. The alarm was triggered by the restart of Russian navigation computers that provide backup attitude control and orbital altitude adjustments.

Flight controllers continue efforts to bring the computers back up to full operation. For now, the station’s control moment gyroscopes are handling attitude control, with the shuttle’s propulsion system providing backup.

Spacewalkers Prep SARJ for Action

Astronauts Patrick Forrester and Steve Swanson continued work to activate the International Space Station’s Starboard 3 and 4 (S3/S4) truss segment during STS-117’s second spacewalk. The 7-hour, 16-minute excursion wrapped up at 9:44 p.m. EDT Wednesday.


The spacewalking duo first assisted with the retraction of the starboard solar array on the Port 6 (P6) truss. They left one launch restraint attached on the S3/S4 Solar Alpha Rotary Joint (SARJ). Flight controllers want to take a closer look at a drive lock assembly on the SARJ. After the launch restraint is removed on an upcoming spacewalk, the rotary joint will allow the S3/S4 arrays to track the sun as the station orbits Earth.

13 of the P6’s 31.5 array bays were retracted Wednesday, and the crew will send commands Thursday to retract the remaining bays. Before moving on to SARJ, Forrester and Swanson “fluffed” the array to allow easier retraction on Thursday.

The retraction of the P6 array clears the line of sight for the S3/S4 arrays to track the sun and sets the stage for the P6’s relocation by a future shuttle crew from atop the station to the end of the Port 5 truss.

Mission Specialist Jim Reilly coordinated the spacewalk, and Pilot Lee Archambault operated the station’s robotic arm. Two more spacewalks are scheduled for STS-117. The next is set for Friday.

In other activities, Expedition 15 Commander Fyodor Yurchikhin and Flight Engineers Oleg Kotov and Clayton Anderson continued to transfer cargo between the station and Space Shuttle Atlantis.

Station Spreads New Wings; Crew Preps for Spacewalk

The International Space Station spread its new set of wings Tuesday, and the STS-117 crew members prepared for the mission’s next spacewalk.


The solar arrays on the newly installed Starboard 3 and 4 (S3/S4) truss segment deployed to their full length with the assistance of the STS-117 crew. The S3/S4 was attached to the station Monday before the start of STS-117’s first spacewalk, during which astronauts began activating the truss. The arrays will increase the station’s ability to generate power when they go online.

Tuesday’s deployment activities occurred in steps, beginning about 11:43 a.m. EDT. The forward-facing array on the S3/S4 was first deployed to its length of 115 feet. The procedure was repeated for the rear-facing array which was fully deployed about 1:58 p.m.

Then, the STS-117 astronauts enjoyed a few hours of off duty time before beginning preparations for the mission’s second spacewalk on Wednesday. Mission Specialists Steve Swanson and Pat Forrester will continue the activation of the S3/S4 and assist in the retraction of the starboard solar array on the Port 6 (P6) truss during the spacewalk. Wednesday’s excursion is scheduled to begin at 2:03 p.m.

The P6 will move from its location atop the station to the end of the Port 5 truss during a future mission.

Late in the workday, STS-117 crew members participated in interviews with CBS News and El Paso, Texas, TV stations KFOX-TV and KTSM-TV.

Astronauts Finish First STS-117 Spacewalk

Mission Specialists Jim Reilly and John “Danny” Olivas successfully completed tasks during STS-117’s first spacewalk to activate the International Space Station’s newest component.

The 6-hour, 15-minute excursion concluded at 10:17 p.m. EDT.

Reilly and Olivas went to work after the Starboard 3 and 4 (S3/S4) truss segment was installed onto the station. They made power, data and cooling connections between the station and the S3/S4. The spacewalkers also released locks and launch restraints on the segment’s solar arrays and prepared its radiator and rotary joint for operation.

The radiator was deployed during the spacewalk. The solar arrays will be unfurled Tuesday. STS-117 Pilot Lee Archambault and Expedition 15 Flight Engineer Oleg Kotov were at the controls of the station’s robotic arm during the spacewalk. STS-117 Mission Specialist Patrick Forrester coordinated the spacewalk.

The start of the spacewalk and the attachment of the truss were delayed due to the saturation of the control moment gyros that control the attitude of the station. Flight controllers performed standard procedures to bring the CMGs back to normal operations.

S3/S4 activation activities will continue during STS-117’s second spacewalk, slated to take place Wednesday afternoon.

Atlantis Docks With Space Station; Spacewalk Set for Monday

After a busy Sunday in which the STS-117 crew arrived at the International Space Station, attention has turned to the mission’s first spacewalk. The excursion, which will focus on the on-orbit assembly of the station, is slated to begin at 1:53 p.m. EDT Monday.

Space Shuttle Atlantis and the STS-117 crew arrived at the station Sunday at 3:36 p.m., delivering a new truss segment and crew member to the orbital outpost. The STS-117 crew entered the station for the first time after the hatches between the shuttle and station opened at 5:04 p.m.


The STS-117 astronauts quickly jumped into joint operations with the station’s Expedition 15 crew. One of the first major tasks was the station crew rotation. STS-117 Mission Specialist Clayton Anderson switched places with Expedition 15 Flight Engineer Suni Williams, who wrapped up a six-month tour of duty as a station crew member.

The crews also began preparations for Monday’s installation of the Starboard 3 and 4 (S3/S4) truss segment and the spacewalk. The crews used the shuttle robotic arm to lift the S3/S4 out of Atlantis’ payload bay and to hand it off to the station arm.

The S3/S4, which contains a new set of solar arrays, is scheduled to be attached to the station prior to the start of the spacewalk conducted by STS-117 Mission Specialists John “Danny” Olivas and Jim Reilly. Olivas and Reilly are spending the night in the station’s Quest Airlock in preparation for the spacewalk.

The BMW M3 Concept Car

You don't notice the green side of BMW's muscular silver M3 concept right away. While the aerodynamics are certainly there, this concept looks - and is - more of a showcase for things like the possible home for a V8 engine than green technology. But BMW engineers didn't totally skip the ecological aspects of the M3. For proof, you have to look down on it.

There is a lot of lightweight engineering in the M3's roof. BMW calls the concept the "latest showcase for BMW's use of advanced weight saving technology," as the roof is constructed from carbon fibre reinforced plastic (CFRP) developed out of Formula One experiences. Reducing the weight of the roof gives the M3 a lower center of gravity, BMW says, and that means a batter balanced car. Now, stick a clean diesel in it, and we'll take it for a drive.


A vision of ultimate driving pleasure

The name M3 is a symbol of unique performance on the racetrack and in everyday motoring. For more than two decades, the BMW M3 has represented the athletic heart of the brand in its most fundamental and succinct form. Its dominating role in motor sports and the ultimate driving experience it affords the driver on the road are inseparably intertwined. Such qualities have given the BMW M3 the exceptional status it enjoys the world over.

At BMW M GmbH, engineers have used this experience to create the new BMW M3 Concept Car. The concept study presented to the public for the first time at the 77th International Motor Show in Geneva (8th to 18th of March, 2007) gives a first impression of what a future BMW M3 might look like.

The BMW M3 Concept Car, with its Chrome Shadow exterior finish characteristic of previous BMW M GmbH concept studies, is a derivative of the new BMW 3 Series Coupé. However, few components are adopted directly from the 'standard' model. Just the headlights, rear light clusters, the two doors and the boot lid are carried over.

All other components were specially engineered for the BMW M3 Concept Car, lending the vehicle a unique look that accentuates its superior power. Features that make the BMW M3 Concept Car stand out are the bespoke front and rear bumper and spoiler designs, a bonnet with a bulging powerdome plus two air vents, side gills complete with M-designation on the front wings, side skirts and double strut exterior mirrors as seen on previous BMW M cars.

Design detail

Faithful to the principle of "form follows function" in designing the body for the concept study, designers at BMW M GmbH used elements that not only visually emphasise the increased sportiness of the vehicle, but also serve a technical purpose. Conspicuous at the front are three large air intakes below the cooling grille that supply the engine with additional intake and cooling air. Strong, vertical struts delineate the air intakes and enhance their characteristic form.

The aluminium engine compartment lid exhibits a wide, bulging powerdome. Like the air vents to either side of it, the powerdome hints at the great potential expected of the powerplant destined for the engine bay of any forthcoming all-new BMW M3. The M3 Concept Car features a high-revving V8 engine that could be used to power a car should it go into production.

The contours of the M3 Concept Car and its bespoke front spoiler and bumper design mean the vehicle is longer than the 'standard' BMW 3 Series Coupé. The muscular front wheel arches of the BMW M3 Concept Car symbolise the high level of agility and driving stability achieved by this vehicle. Together with the forged 19-inch Y-spoke design light alloy rims, the vehicle's wide track is emphasised, while a glance through the spokes of the rims reveals the compound high performance brakes developed exclusively for previous M vehicles.

The opening behind the wheel arch on the front wing has an elaborate form that is split by a discreet chrome bracket containing the direction indicator and the M3 logo. Two arched surfaces form the pronounced side skirt, creating a distinct contrast between light and shadow. The incidence of light on the sharply defined rear wing and wheel stresses the dynamic character of the vehicle and visually highlights its rear-wheel drive configuration.

Exclusive exterior mirrors developed for the BMW M3 Concept Car feature black double connecting struts. Even this small detail is in keeping with the principle of "form follows function". With their horizontal contour line and tapered outward shape, the mirrors not only contribute to the overall impression of the vehicle, but also to their aerodynamic profile, keeping drag to a minimum.

The rear of the M3 Concept Car further enhances the muscular stance of the vehicle. A discreet spoiler lip on the boot lid, also called a Gurney flap, channels the air at the rear for optimum downforce while reducing lift on the rear axle. The contours of the diffuser, the design of which is subdivided by modelled struts, mirror the shape of the air intakes at the front. The diffuser and the double exhaust tailpipes positioned close to the vehicle's longitudinal axis appear to pull the rear together at the centre and build up a tension in conjunction with the horizontal lines of the bumper.

Intelligent lightweight engineering

The BMW M3 Concept Car is the latest showcase for BMW's use of advanced weight saving technology and the clearest demonstration of this on the car is its roof. Specialists at the BMW Plant in Landshut, Germany, constructed the carbon fibre reinforced plastic (CFRP) roof using an exclusive production method taken from the firm's experience in Formula One. Courtesy of a clear lacquer the carbon-fibre weave is still clearly visible.

As a highly visible advanced technology component, the CFRP roof dominates the technically innovative appearance of the BMW M3 Concept Car. Seen from the side, the roof edge appears flatter and thus lowers the perceived body height. Apart from the appearance, the CFRP roof also offers a real technical advantage being considerably lighter than a steel roof. This not only reduces the overall vehicle weight, but by reducing the weight of the highest element in the body, the centre of gravity is also lowered to produce a better balanced car. The CFRP roof is a perfect example of how interlinking technical innovation with an individual design strategy was central to the development of the BMW M3 Concept Car.

Following the tradition of the previous three generations of the BMW M3, this concept study represents a high performance sports car interpreted for use in everyday driving. The BMW M3 Concept Car shows where the ultimate driving experience strategy will take BMW in the future.

You Can't Travel Back in Time

The urge to hug a departed loved once again or prevent atrocities are among the compelling reasons that keep the notion of time travel alive in the minds of many. While the idea makes for great fiction, traveling to the past is impossible as of now to say the least.

In physics, time is described as a dimension much like length, width, and height. When you travel from your house to the grocery store, you’re traveling through a direction in space, making headway in all the spatial dimensions—length, width and height. But you’re also traveling forward in time, the fourth dimension. Space and time are tangled together in a sort of a four-dimensional fabric called space-time



Space-time, can be thought of as a piece of spandex with four dimensions. When something that has mass—you and I, an object, a planet, or any star—sits in that piece of four-dimensional spandex, it causes it to create a dimpl. That dimple is a manifestation of space-time bending to accommodate this mass. The bending of space-time causes objects to move on a curved path and that curvature of space is what we know as gravity. Mathematically one can go backwards or forwards in the three spatial dimensions. But time doesn’t share this multi-directional freedom. In this four-dimensional space-time, you’re only able to move forward in time.

A handful of proposals exist for time travel. The most developed of these approaches involves a wormhole—a hypothetical tunnel connecting two regions of space-time. The regions bridged could be two completely different universes or two parts of one universe. Matter can travel through either mouth of the wormhole to reach a destination on the other side. Wormholes are the future, wormholes are the past of Hyperspace and Parallel Worlds. But we have to be very careful. The gasoline necessary to energize a time machine is far beyond anything that we can assemble with today’s technology. To punch a hole into the fabric of space-time, we would require the energy of a star or negative energy, an exotic entity with an energy of less than nothing.

Another popular theory for potential time travelers involves something called cosmic strings—narrow tubes of energy stretched across the entire length of the ever-expanding universe. These skinny regions, leftover from the early cosmos, are predicted to contain huge amounts of mass and therefore could warp the space-time around them. Cosmic strings are either infinite or they’re in loops, with no ends - something like a spaghetti. The approach of two such strings parallel to each other will bend space-time so vigorously and in such a particular configuration that might make time travel possible, at least in theory.

This is a project that a super civilization might attempt.It’s far beyond what we can do. We’re a civilization that’s not even controlling the energy resources of our planet.

Mathematically, you can certainly say something is traveling to the past. But it is not possible for you and me to travel backward in time.However, some scientists believe that traveling to the past is, in fact, theoretically possible, though impractical.

Maybe if there were a theory of everything, one could solve all of Einstein’s equations through a wormhole, and see whether time travel is really possible. But that would require a technology far more advanced than anything we can muster. Don’t expect any young inventor to announce tomorrow in a press release that he or she has invented a time machine in their basement.

For now, the only definitive part of travel in the fourth dimension is that we’re stepping further into the future with each passing moment. So for those hoping to see Earth a million years from now, scientists have good news.

If you want to know what the Earth is like one million years from now, I’ll tell you how to do that. Build a spaceship. Go near the speed of light for a length of time—that I could calculate. Come back to Earth, and when you step out of your ship you will have aged perhaps one year while the Earth would have aged one million years. You would have traveled to Earth’s future.

The positive spectrum of the 7 human emotions will drive us to pleasure and that is why we pursue them. The negative spectrum of the 7 human emotions will drive us towards pain and that is why we will do anything to avoid it. It is also important to notice that we will do more to
avoid painful emotions than we will do to gain pleasurable emotions as this is instinctive to our nature as human beings.


The 7 human emotions of Pain are:
1. Fear
2. Hatred
3. Anger
4. Greed
5. Jealousy
6. Revenge
7. Superstition

These are the emotions we are all trying to avoid as the experience of them will inevitable be a painful emotion.

The 7 human emotions of pleasure are:
1. Love
2. Sex
3. Hope
4. Faith
5. Sympathy
6. Optimism
7. Loyalty

"The secret of success is learning to use pain and pleasure instead of having pain and pleasure use you. If you do that you are in control of your life. If you don't
life controls you" - Anthony Robbins.

All emotions serve a purpose and a very important purpose as such. We all want to experience the positive side of the 7 human emotions and often we seek for it in the wrong places. Drugs, alcohol, smoking ex. are all devises we use to get out of pain and into pleasure. They are things we do to instantaneously suppress the negative emotions we may experience. The truth is that suppressing or ignoring an emotion will only amplify it until you deal with it. If we heed and utilize the signals that emotions give us we can change the quality of our lives and experience of life immediately.

The reality behind Indian IT Cos

All too often globalisation is invoked as though it were a rallying cry with the potential to inspire national economic growth, consumer aspiration and new forms of lifestyle, with the accent on the style. However, globalisation is no virtual phenomenon. It is a set of concrete processes with real-time effects on our lives. And it is precisely in this tension between the idea of globalisation as representing an onward and upward march toward economic prosperity and the material implications of globalisation as lived experience that we observe the contradictions of the present moment even for those regarded as key beneficiaries, namely, those in Information Technology and Business Process Outsourcing. Despite differences within as well as across the IT and BPO segment, I consider the two as a whole here, since my interest is in certain problems that cut across the industry.

Alongside the print media glorification of the lifestyle of those in IT/BPO (often treated as if it were a distinct social category of hard workers and big spenders) there have been increasing reports of employee dissatisfaction with conditions of work. These include the deleterious consequences of long working hours, constant deadlines, night shifts, and the shrinking of social and leisure time. Quality of life issues seem to outweigh the question of the much envied and remarked upon high levels of remuneration. A working environment geared to "delivering no matter what" has led to complaints that even leave to attend to family emergencies have required negotiation or struggle. Additionally, those in customer care face the hostility of the very persons for whose comfort accents are altered, false identities are created, and most Indian holidays are forgone.

Outsourcing may have come to stay, but the conditions in which it is undertaken are surely amenable to change. We might wish to consider questions about the future to which IT/BPO employees are being invited to commit themselves. Is it worth expending one's youth and/or health in this way? How long can one's work routines distort the organic balance between mind and body, sleeping and waking, focusing and relaxing before we trigger a psychological or physiological collapse? It should be noted that

It is also worth pondering how much of the work in the outsourcing sector is truly cutting edge and how much clerical in nature or maintenance in function. The point is not that the latter kinds of work are undignified, but whether service or tedious work is being falsely represented as executive in nature and whether the conditions of work befit the inherent dignity of employees. The answers to such questions lie in the material conditions of work. By this I do not mean the air conditioning, landscaping, gyms and other facilities (the lifestyle indices, as it were), but the nitty gritty of the organization of work- work load, expectations of hours put in, business culture etc. The former cannot compensate for the latter except in the idealised world of advertising or in the abstract promises of the cheer leaders of globalisation.

The Visteon Story

So like you all know am now on the rolls of the second largest automotive component maker in the world. I just hit upon a story about how it all started for Visteon and I wanna share that with you people. Keep reading!

The year 2000 and on the battle grounds were two behemoths of the American Automobile world - Ford and General Motors. Ford, in a fitting reply to GM's Delphi, helped organize in 10 months and which stays the second largest in the world right from the start. It is a company with a visionary, passionate leader, Charlie Szuluk. Its name: Visteon.

Charlie Szuluk, says Steve Delaney, is a man who has the inspirational qualities that can cause people to do things that they might not expect they'd be likely to do or be capable of doing. He's motivational, demanding, persuasive, and driven. When Szuluk urges, "Think breakthrough, think out of the box," the words resonate with passion, not empty platitude. When he describes what must be done is to "Make the customer successful," it is clear that fulfilling rote requirements doesn't cut it. Perhaps it is not surprising, then, that Szuluk is the man who is the president of a new organization formed by Ford Motor Co., an organization - or, as it is stated on the firm's business cards, an enterprise - that is unlike anything Ford has done in the past.

This enterprise, which is a reorganized array of the resources that had heretofore been Ford Automotive Products Operations, is both a part of Ford and, in a real sense, apart from Ford. That is, although it is a supplier to Ford, a supplier that Ford, in fact, owns, it is apart from the automaker in that not only does it have its own logo and identity - with nary a blue oval with flowing white script in sight - but Szuluk's mission, which he is taking on along with 78,000 others in the effort, is to get as much non-Ford business as is possible. This means, of course, working for other automakers. And if Szuluk's charisma and the enterprise's global design, engineering and manufacturing capabilities matter, then they should be getting plenty of orders.

Delaney, like Szuluk, began his career with IBM. Delaney was with IBM for seven years; Szuluk was with Big Blue for 24. Delaney joined Ford Electronics Div. in 1989 as an engineer. Szuluk joined that division in 1988 as general manufacturing manager. Delaney went on to become plant manager of the Ford Markham Electronics Plant, then, in 1994, joined Ford's new Process Leadership initiative as area manager of the Ford Production System. Szuluk became general manager of Ford Electronics Div. in 1991, became vice president of Process Leadership in 1994, and was named group vice president of the then newly formed Ford Automotive Products Operations on November 1, 1996. Delaney had left Ford in January 1996, when he joined AlliedSignal Aerospace Electronics Systems as vice president, Operations. Delaney says that it was a good opportunity, particularly being able to work with a leader like Larry Bossidy of AlliedSignal. But then he was called by Charlie Szuluk, the man who insists, "We will be the best." And Delaney was let in on the vision that Szuluk had for a new type of supplier organization, the vision that would be given public life at a worldwide announcement in September 1997. Delaney was convinced by Szuluk to return to Ford, which he did in February 1997. He is now vice president, Supply and Logistics for Visteon.

The paths of the two men - fast tracks that are not exactly typical for the auto industry - are indicative of the nature of the new company.
"Our number-one resource," says Szuluk, "is our outstanding people, who make outstanding products."

Plenty of executives say things like that. Few of them really believe it. Szuluk is numbered among the few. He recalls his travels in the early '90s when Ford was building electronics plants in countries around the world. "Wherever I went, I found out that if we set stretch objectives, and our people put their mind to them, and understood that management had confidence in their ability to reach the objectives, there really wasn't anything they couldn't do. Meeting stretch objectives for our customers will drive our success."

One of the things that Szuluk says Visteon will be doing is paying attention to cost reduction efforts while making advances in technology. He maintains that while cost is certainly an Important component to any calculations, as a supplier company, full focus on cost is an insufficient approach to being a competitor. "People who rely on low cost as a strategy and chase that don't do as well as those companies that both provide low costs and develop technology," he says. Certainly, flit is an issue of piece-part costs alone, companies can go chasing low labor rates and favorable exchange rates all over the world. Szuluk observes, "If a company is just focusing on things like labor costs, they can't win in this environment." As he puts it, "What's the differentiator?" That is, there is probably not a long-term advantage for any company that's competing on price alone, because in all likelihood there is another company somewhere that will be able to produce the component at a still lower price. If a company is able to combine other attributes - such as rapid product development coupled with lean manufacturing and excellent delivery logistics - then it becomes a more valuable company. And this is Visteon's approach.

India's problems depsite its high growth rate

The economy is sizzling and foreign businessmen and investors are swarming to Bangalore and Mumbai to grab a piece of the action. India's year-on-year growth rate could well hit double figures at some point in 2007, and the country may even grow faster than China for at least one quarter. But things are so hot there is a big problem: India's current pace of expansion may not be sustainable.

On the face of it, the figures are compelling. India's real GDP grew by 9.2 per cent in the year to last September. Over the past four years it has clocked up an average annual pace of more than 8 per cent, compared with around 6 per cent in the 1980s and 1990s and a measly 3.5 per cent during the three decades before 1980. But the economy is displaying alarming symptoms of overheating. This implies that demand is outpacing supply and hence the pace of growth is unsustainable.


All agree that the biggest obstacle to growth of 9 per cent or more is India's infrastructure - especially its lousy roads, ports and power. According to the World Bank, the average manufacturing firm loses 8 per cent of sales each year from power cuts. India spends 4 per cent of its GDP on infrastructure investment, compared with China's 9 per cent. In absolute dollar terms, China spends seven times as much on its infrastructure.

India's government has ambitious plans to increase total infrastructure spending to 8 per cent of GDP over the next five years. This will involve some increase in government spending, but the idea is for the bulk of it to be financed by public-private partnerships. That will be hard. Private investors still shy away from sectors like electricity and roads because they are uncertain of earning a reasonable return. Only about half of all electricity generated is paid for, because power is stolen and bills are left unpaid.

Another big problem is the dreadful quality of public services, from education and health to the provision of water. Half of urban households lack drinking water within the home; one quarter have no access to a toilet, either public or private. Many public services in cities have worsened in recent years. In Bangalore water is now available for less than three hours a day, compared with 20 hours in the early 1980s. This may be another reason why workers are not moving in from rural areas as rapidly as in China.

But the coolest of all news is that am on the rolls of Visteon Corporation - the second largest auto component maker next only to Delphi and after all, this is what I wanted to do with my life after many a things have gone wrong. So finally God heard me and here I am ready to furbish my resume with all those wonderful names - BMW, VW, Honda, Ford, Aston Martin....sends your eyes rolling eh? It has to. To me its no different than being at Boeing or Lockheed Martin - am gonna work on cutting edge stuff here too and the good thing is no clearence required. The crappy US laws can go to hell now. For those people who still dont get me - keep coming back to the blog. Perhaps you will get to know the similarities between Automotive and Aerospace.
