Absolutely remarkable exterior panoramic photos of the ISS and tributes by Shuttle Astronauts marked two major milestones in spaceflight history today, May 27; the last spacewalk ever by Space Shuttle Astronauts and the formal completion of the US segment of the International Space Station after 12 years of construction.

Today’s spacewalk by shuttle Endeavour Astronauts Mike Fincke and Greg Chamitoff was the last ever outing in the three decade history of NASA’s Space Shuttle Program.

Check out the breathtaking photos taken by the astronauts today showing a wide angle view of the complex, including all of shuttle Endeavour at one end and a Russian Soyuz at the other end – backdropped by Earth.

The seven-hour, 24-minute spacewalk was the fourth and final EVA of the STS-134 mission and simultaneously finished the assembly of the US portion of the orbiting lab complex.

The primary objectives of the spacewalk were to attach Endeavour’s 50-foot-long Orbiter Boom Sensing System (OBSS) and install a new grapple fixture to make the OBSS available to significantly extend the reach of the space station’s robotic arm. The OBSS was used to examine the shuttle’s heat shield tiles. But they are no longer needed aboard the shuttles since they are being retired and was therefore permanently handed over from Endeavour to the station.

This spacewalk was the 159th in support of assembly and maintenance of the ISS which now totals more than 1000 hours of astronaut and cosmonauts work time.

On today's spacewalk @Astro_Taz took the most amazing #ISS px ever Can't wait to see @Astro_Paolo 's from Soyuz.

Gregory Chamitoff marked the milestones with these words of tribute; “At this time, now that we’re almost done here, I wanted to say a few words. This is the last flight of the space shuttle Endeavour and it’s also the last spacewalk of shuttle crew members in station assembly.

“It’s kind of fitting that Endeavour is here because Endeavour was the first shuttle to begin construction of the station and so it’s fitting that she’s here for the last mission to finish assembly.

“During this EVA, we tallied altogether collectively over a thousand hours of spacewalks as part of station assembly. Mike and I have the honor here to share this last spacewalk and of course, with all the folks working on the ground, the thousands of people who helped build this, working in the shuttle and the station programs.

“We’re floating here on the shoulders of giants. This space station is a pinnacle of human achievement and international cooperation — 12 years of building and 15 countries. And now it’s the brightest star in the sky and hopefully the doorstep to our future. So congratulations everybody on assembly complete,” said Chamitoff.

From inside the Quest airlock, Mike Fincke took his turn and added these comments, “I wanted to say congratulations to the shuttle program for all the wonderful successes we’ve had over the past 30-something years. It’s a privilege that Endeavour’s hosting the last spacewalk by a space shuttle crew. So congratulations to the EVA development teams. We’ve come a long way. From me and Greg and the rest of the crew, congratulations.”

Today, Fincke also claimed the record for most time in space by a US astronaut, surpassing Peggy Whitson’s record of 377 days in space.

As the shuttle era frenetically draws to a close, the launch views of the thunderous climb to orbit captured by NASA just get ever more stunning and vividly illustrate what it’s like to liftoff to space.

Check out this awesome collection of high definition videos of Endeavour’s final blast off as recorded by cameras mounted on each of the twin solid rocket boosters (SRB’s) from multiple viewpoints.

The STS-134 mission lifted off on May 16 from the Kennedy Space Center in Florida. The cameras show the launch from numerous spectacular angles and vantage points, pointed down to Earth and up to space, from alongside the belly of the orbiter and along the sides of the SRB’s.

The videos show all the phases of the SRB in flight – including separation, parachute deployment and all the way to the dramatic splashdown in the Atlantic Ocean with rapidly changing backgrounds of the launch pad, Earth and Space.

The STS-134 mission is the 25th and final flight of Space Shuttle Endeavour, NASA youngest orbiter.

Endeavour’s six man crew is led by Shuttle Commander Mark Kelly, husband of Rep. Gabrielle Giffords. She was shot at point blank range and critically wounded during a routine congressional meet and greet with her constituents in January 2011.

Endeavour is set to land back at KSC on June 1 at 2:32 a.m. EDT after a 16 day mission to the International Space Station. The crew carried up the $2 Billion Alpha Magnetic Spectrometer and attached this wor;ld class science instrument to the truss of the ISS. The AMS is a particle physics detector searching for antimatter, dark energy and dark matter. The goal is to elucidate the birth and evolution of the Universe.

KENNEDY SPACE CENTER – Unprecedented and spectacular photos showing a US Space Shuttle Orbiter docked to the International Space Station (ISS) were snapped just hours ago and transmitted live back to ground stations and viewers on Earth as a Soyuz capsule with three space flyers departed from the station at 5:35 p.m EDT on the first leg of their journey back to Earth. And the best is yet to come.

Check out the photo galley of historic black and white gems captured from an engineering docking camera attached to the nose of the Russian Soyuz capsule that undocked this evening (May 23) from the ISS. These historic photos are the first ever showing a shuttle joined to the massive orbiting complex.

As the Soyuz was backing away from the Russian-built Rassvet module, Italian Astronaut Paolo Nespoli was busily snapping first of its kind high resolution color photos and videos of Space Shuttle Endeavour attached to the ISS.

The entire complex was simultaneously rotated 130 degrees to provide the best possible view of the whole shuttle-station stack. The combined stack weighs more than a million pounds

Nespoli had about 30 minutes to collect high resolution digital imagery from a viewing port inside the habitation module of the Soyuz spacecraft that burns up on reentry. He then removed the cards from the cameras and floated back into the Soyuz descent module.

NASA and Russia expect to release high resolution digital imagery on Tuesday or Wednesday.

The three person Expedition 27 crew comprising of Commander Dmitry Kondratyev and Flight Engineers Cady Coleman and Paolo Nespoli landed safely in their Soyuz spacecraft on the Kazakhstan steppe Monday at 10:27 p.m. (8:27 a.m. on May 24 local time) at a site southeast of the town of Dzhezkazgan.

Shuttle Endeavour is in the middle of the 16 day STS-134 mission and delivered the $2 Billion Alpha Magnetic Spectrometer to the ISS. The AMS is a particle physics detector searching for the invisible Universe and seeks to elucidate its birth and evolution. The all veteran crew of 6 is led by Shuttle Commander Mark Kelly.

KENNEDY SPACE CENTER: Get ready for the ultimate photo op in space – set for the International Space Station joined to Space Shuttle Endeavour and topped off by Planet Earth as the backdrop.

And it’s coming up momentarily because of an unexpected and “unique opportunity” that’s also taking place at nearly the last possible moment in the life of the soon to be retired Space Shuttle program.

On Monday, May 23, Italian Astronaut Paolo Nespoli will snap the first ever photos and video of a US Space Shuttle orbiter while it is simultaneously still docked to the International Space Station, NASA officials just announced on Friday, May 19.

Video Caption: This computer generated animation depicts the view the Soyuz crew will see as they depart from the International Space Station (upper left) on May 23, 2011 at 5:32 p.m. EDT.

Nespoli will capture the dramatic and historic imagery – in a newly devised plan – while he is departing the “Shuttle- Station stack” aboard a Russian Soyuz spacecraft and heading for a landing back on Earth with two crewmates barely 4 hours later in Kazakhstan.

“We have a unique opportunity. We are calling this Soyuz undock with imagery,” said Kenneth Todd, chair of NASA’s space station mission management team. “We are not calling this a Soyuz flyaround or flyabout.”

“This is going to be a great opportunity for the spaceflight community.”

After months of high level international negotiations since the STS-133 mission, NASA and Russian space officials from the space shuttle and space station teams have finally agreed on a arrangement for utilizing a crewed Soyuz vehicle to record the first ever photos showing a shuttle while still docked to the massive orbiting outpost in the same field of view.

The chance to do the shuttle- station photo documentation in this way only became possible when the launch of Space Shuttle Endeavour was scrubbed on April 29 and the resulting delayed launch of the STS-134 mission on May 16 fortuitously afforded an overlapping time period that coincided with the Soyuz TMA-20 crew departure.

The photo opportunity will take place under what’s called a dual docked operations scenario whereby the Soyuz is undocked while a shuttle is still attached to the ISS.

“With 100 percent consensus, we approved this change to the baseline mission to go add this photo documentation task as part of the Soyuz TMA-20 undock,” Todd explained.

In order to accommodate the extra time required to accomplish the photo shoot, the Soyuz TMA-20 capsule will undock from the ISS one orbit earlier than originally scheduled, about 90 minutes, at 5:32 p.m. EDT.

Nespoli is departing with ISS Expedition 27 commander and Russian cosmonaut Dimitry Kondratyev and NASA astronaut Catherine “Cady” Coleman. They will be completing a nearly six month stint in space aboard the ISS.”

“After the Soyuz undocks, they will back out to about 200 meters,” explained Courtney McMillan, STS-134 Station Team 4 Flight Director. “You will see they are a little bit above the velocity vector, above the station, and that is to keep the sun out of the pilot’s eyes.”

“After they get to the station keeping point, ISS will begin to maneuver, turning 130 degrees at 0.2 degrees per second.” The attitude was designed to provide the best perspective of the ISS and Endeavour.

“It will take 15 minutes to bring the whole stack around to get a side view and a really good view of Endeavour. This is an unusual attitude for the station to fly during a mated mission and people have done a lot of work to make sure this is a good thing to be doing. They have scrutinized the issue and are very comfortable with the plan.”

The station move will be done using thrusters on the Russian Segment service module – named Zvezda – and the thrusters on the docked Progress 42P vehicle, an unmanned Russian cargo ship. See diagram below.

Nespoli will have to float into the Soyuz vehicles forward habitation module – from his seat in the central descent module – and then snap the photo and video imagery through the modules windows. He will have a direct line of sight to the stack.

Paolo will have roughly 30 minutes time to collect all the imagery of the combined space complex during the photo survey, starting at about 5:50 p.m. EDT.

Then he will float back out of the habitation module, carefully seal the hatches in between and take his seat in the descent module.

The habitation module burns up in Earth orbit after the modules separate in preparation for the Soyuz’s deorbit and scorching reentry into Earth’s atmosphere.

Since the Soyuz will be pitched up during the undocking sequence, breathtaking views of Earth in the background of the “Shuttle-
Station stack” are expected.

The goal is to get good archival imagery of the space station stack with the shuttle attached. In addition to the gee whiz factor there are good reasons from an engineering perspective to record this imagery to assess the condition of the orbiting complex, NASA managers said.

“Future generations will look back on their history and look back at what we accomplished between these two very, very large programs – the shuttle and the space station – and realize it was amazing what we accomplished with the technology available at the time.”

“These pictures will be in textbooks to show what we did”, said Todd.

Exactly when the digital photos and video will be available for all to see is still to be determined. NASA and Russian space officials are discussing the details of when and how to distribute the imagery. The Soyuz is not equipped to transmit the imagery in real time.

“We hope to start seeing the photos and videos within a day of landing”, said Todd.

Paolo has snapped many gorgeous shots during his stay in space, including these of an Ariane V launching the European ATV cargo craft from French Guiana.

Go Paolo !

KENNEDY SPACE CENTER – The end of NASA’s shuttle era has begun as pre-launch preparations for the final shuttle flight by Space Shuttle Atlantis kicked into high gear. The STS-135 mission is set to launch on July 8 at about 11:40 a.m. EDT on a 12 day flight.

Shuttle Atlantis has been moved about a quarter of a mile from its pre-launch processing hanger – known as Orbiter Processing Facility-1 (OPF-1) – to the Vehicle Assembly Building (VAB) at the Kennedy Space Center in Florida. Check out our eyewitness photo album herein.

More than a hundred photo journalists representing media worldwide gathered to watch this historic event – known as “rollover”. I had a chance to briefly speak and shake hands with Shuttle Commander Chris Ferguson and wish the crew good luck.

Under a gorgeous clear blue sky, Atlantis was hauled to the VAB – while bolted atop a 78 wheeled transporter – a key milestone setting a clear path to blastoff. Inside the VAB, the orbiter is mated to the external fuel tank and solid rocket boosters before rolling out to Launch Pad 39 A in about two weeks.

Midway through the road trip, Atlantis was parked for several hours to allow KSC employees to pose for photo opportunities with the flight ready orbiter for the last time.

The goal of Atlantis mission is to carry the Raffaello multipurpose logistics module (MPLM) to the International Space Station (ISS) and stock up the orbiting outpost with science equipment, crew supplies, food, water, logistics, gear and spare parts before the shuttles are retired forever at the prime of their lifetime.

Lone Planets “More Common Than Stars”

Artist's concept of a free-floating Jupiter-like planet. (NASA / JPL-Caltech)

[/caption]

We happen to live in a solar system where everything seems to be tucked neatly in place. Sun, planets, moons, asteroids, comets… all turning and traveling through space in relatively neat and orderly fashions. But that may not always be the case; sometimes planets can get kicked out of their solar systems entirely, banished to roam interstellar space without a sun of their own. And these “orphan planets” may be much more numerous than once thought.

Researchers in a joint Japan-New Zealand study surveyed microlensing events near the central part of our galaxy during 2006 and 2007 and identified up to 10 Jupiter-sized orphan worlds between 10,000 and 20,000 light-years away. Based on the number of planets identified and the area studied they estimate that there could literally be hundreds of billions of these lone planets roaming our galaxy….literally twice as many planets as there are stars.

“Although free-floating planets have been predicted, they finally have been detected, holding major implications for planetary formation and evolution models.”

– Mario Perez, exoplanet program scientist at NASA Headquarters in Washington.

From the NASA release:

Previous observations spotted a handful of free-floating, planet-like objects within star-forming clusters, with masses three times that of Jupiter. But scientists suspect the gaseous bodies form more like stars than planets. These small, dim orbs, called brown dwarfs, grow from collapsing balls of gas and dust, but lack the mass to ignite their nuclear fuel and shine with starlight. It is thought the smallest brown dwarfs are approximately the size of large planets.

On the other hand, it is likely that some planets are ejected from their early, turbulent solar systems, due to close gravitational encounters with other planets or stars. Without a star to circle, these planets would move through the galaxy as our sun and other stars do, in stable orbits around the galaxy’s center. The discovery of 10 free-floating Jupiters supports the ejection scenario, though it’s possible both mechanisms are at play.

“If free-floating planets formed like stars, then we would have expected to see only one or two of them in our survey instead of 10. Our results suggest that planetary systems often become unstable, with planets being kicked out from their places of birth.”

– David Bennett, a NASA and National Science Foundation-funded co-author of the study from the University of Notre Dame.

The study wasn’t able to resolve planets smaller than Saturn but it’s believed there are likely many more smaller, Earth-sized worlds than large Jupiter-sized ones.

The study, led by Takahiro Sumi from Osaka University in Japan, appears in the May 19 issue of the journal Nature.

[/caption]KENNEDY SPACE CENTER – The second time was a charm for Space Shuttle Endeavour as she blasted off this morning (May 16) from Pad 39 A at the Kennedy Space Center on her historic final mission under overcast skies after a two week delay caused by a heater malfunction in the orbiters critical hydraulic fuel lines.

The threatening clouds moved in over the pad in the last 30 minutes of the countdown and nearly derailed the launch. Forecasters had predicted a 70 chance of favorable conditions.

The Universe Today team of Ken Kremer and Alan Walters witnessed Endeavour’s exciting launch from the press site next to the world famous countdown clock. Check out our photo album here.

Shuttle Commander Mark Kelly and his five crewmates lifted off at 8:56 a.m. EDT Monday on the STS-134 mission which will deliver a state of the art particle physics detector to the International Space Station.

The $2 Billion Alpha Magnetic Spectrometer (AMS) could potentially revolutionize our understanding of how the Universe was born and evolved over time. The AMS is a world class science instrument sponsored by the United States and 15 countries around the globe. Nobel Prize Winner Samuel Ting of MIT leads the international science project.

Endeavour’s three main engines roared to life six seconds before the twin Solid Rocket Boosters were ignited and pushed the shuttle off the pad atop a tremendous roar and brilliant flames shooting from Endeavour’s tail.

The blastoff was flawless and majestic. Endeavour disappeared into the clouds at about T plus 25 seconds

Nearly half a million people flocked to the Florida Space Coast to be a part of history and witness the launch of Shuttle Endeavour on her 25th and final mission to space. Many hotels were sold out for the night.

Numerous folks staked out their claim to a prime view location along area waterways and beaches by camping out for the night or by arriving many hours early to avoid the crush and clogged local roadways.

Kelly’s crewmates are Pilot Greg H. Johnson and Mission Specialists Mike Fincke, Drew Feustel, Greg Chamitoff and Roberto Vittori of the European Space Agency. This is the first shuttle flight for Fincke and Vittori.

“This mission represents the power of teamwork, commitment and exploration,” Commander Mark Kelly said shortly before liftoff. “It is in the DNA of our great country to reach for the stars and explore. We must not stop. To all the millions watching today including our spouses, children, family and friends, we thank you for your support.”

Both Finke and Vittori flew to space atop Russian rockets on their prior spaceflights. Vittori will be the last international astronaut to fly aboard a shuttle.

Endeavour is slated for a 16 day mission to the International Space Station which will include the final four spacewalks for the space shuttle program.

The STS-134 mission is the penultimate flight of the shuttle program and the 25th and final one for shuttle Endeavour, NASA’s youngest Orbiter.

KENNEDY SPACE CENTER – A humongous crowd numbering perhaps half a million excited people is expected to witness the historic final blast off of Space Shuttle Endeavour.

Clocks are ticking down as the countdown enters the final phase before Monday morning’s liftoff (May 16) scheduled for 8:56 a.m. EDT from Pad 39 A at NASA’s Kennedy Space Center (KSC).

Endeavour was unveiled for blastoff earlier today as a protective cocoon like structure was pulled away from the shuttle stack. The Rotating Service Structure (RSS) was retracted from around the orbiter starting at 11:45 a.m. over about 45 minutes and under a gorgeous blue sky. See my photo album

In a lucky break, expected thunderstorms that could have delayed the retraction and launch preparations actually passed through the area overnight, much earlier than expected.

Shuttle managers will gather at 11 p.m. tonight for a critical meeting and decision to give the “Go-No Go” directive to load the External Fuel Tank with supercold liquid hydrogen and liquid oxygen fuel that powers the shuttle main engines for the eight and one half minute climb to orbit. The tanking process is scheduled to begin at 11:36 p.m.

There are no technical issues at this time that would prevent a launch. The weather outlook remains at “70 Percent GO”.

The goal of Endeavour and her all veteran six man crew is to deliver the Alpha Magnetic Spectrometer (AMS) to the International Space Station. The $2 Billion AMS is a state of the art particle physics detector that will search for dark matter, dark energy and antimatter and seek to determine how the Universe was born and evolved.

The 134 mission is set to last 16 days and will feature the final 4 spacewalks of the space shuttle program.

The crew will wake up at 12 a.m. Monday. They depart for the launch pad shortly after 5 a.m.

Launch coverage begins on NASA TV tonight at 11:30 P.M. shortly before fueling commences:

KENNEDY SPACE CENTER – Space Shuttle Endeavour is poised for launch as the countdown clock ticks down to a liftoff from Pad 39 A on Monday morning, May 16 at 8:56 a.m. EDT. The shuttle Mission Management Team (MMT) at the Kennedy Space Center (KSC) met today (May 14) and gave the green light to continue launch preparations for the STS-134 mission, which is the final flight of shuttle Endeavour.

The weather forecast remains at a 70 percent favorable chance of acceptable conditions on Monday, according to Shuttle Weather Officer Kathy Winters. The weather outlook drops to only 20 percent favorable on Tuesday in case of a one day delay. The weather rebounds to 80 percent favorable if the launch is postponed by 48 hours.

At a briefing for reporters at KSC today, shuttle launch managers were upbeat about preparations for the launch.

“We had a really good meeting today, unanimous consent from the Mission Management Team to press on with the launch countdown,” said Mike Moses, MMT chairman and manager of shuttle integration at KSC. “Everything’s in really great shape, really no issues at all.”

Moses added that no problems are expected with the heaters in the auxiliary power units (APU’s) that caused the launch scrub two weeks ago on April 29.

Shuttle Launch Director Mike Leinbach said, “The countdown is going extremely well and the team is ready to go. Tanking of the External Tank begins just prior to midnight. We are not working any issue at this time.”

Fueling of the External Tank with supercold liquid oxygen and liquid hydrogen starts at 11.36 p.m. Sunday night.

Leinbach said that local officials are expecting a crowd of about half a million people to descend on the Florida Space Coast area for the launch.

“You’ll recall for the first launch attempt on that Friday afternoon, the estimate was between 500,000 and 750,000,” he said. “So they’re not quite expecting that big surge, but it’ll still be a heck of a traffic jam after launch.”

Endeavour and her six man crew will deliver the $2 Billion Alpha Magnetic Spectrometer – a particle physics detector searching for dark matter, dark energy and antimatter – to the International Space Station during a 16 day mission that will include 4 spacewalks.

After Endeavour was rolled out to the pad, I had an awesome opportunity to photograph Endeavour at the pad from stunning vantage points all around the launch pad from top to bottom.

Herein is part 2 of my photo album focusing on my visit to the base of the shuttle stack on the mobile launch platform while looking to the heavens and standing directly beneath the External Tank and in between the Twin Solid Rocket Boosters. Part 1 of my photo album concentrated on the view from the upper levels and our visit to the White Room – where the astronauts board the shuttle orbiter to take their seats for the adventure of a lifetime.

Endeavour Astronauts Arrive at Cape for May 16 Launch

The STS-134 crew arrived at the Shuttle Landing Facility at NASA’s Kennedy Space Center on May 12, 2011. The crew is preparing for the liftoff of space shuttle Endeavour at 8:56 a.m. EDT on Monday, May 16. From left are, Commander Mark Kelly, Mission Specialists Greg Chamitoff, Andrew Feustel, European Space Agency astronaut Roberto Vittori, Mission Specialist Mike Fincke and Pilot Greg H. Johnson.

KENNEDY SPACE CENTER – The all veteran crew for the last launch of Space Shuttle Endeavour flew back to Florida today for their second try to lift off into space on the STS-134 mission to the International Space Station. This follows the launch scrub called by Shuttle launch managers on April 29 caused by a malfunction of critical heaters inside one of the orbiters three auxiliary power units (APU’s) which power the ships hydraulics.

The weather forecast for Monday morning launch is currently “70% GO” and liftoff is targeted for 8:56 a.m. EDT on Monday, May 16. Stormy weather and rain is expected to sweep across central Florida over the weekend and clear out in time for the launch. But Sunday’s rain could potentially delay the retraction of the Rotating Service Structure – which protects the shuttle from bad weather – for a short time.

Shuttle Commander Mark Kelly and his five crewmates arrived at the Shuttle Landing Facility at the Kennedy Space Center early this morning (May 12) at 9 a.m. aboard the Shuttle Training Aircraft (STA) after flying in from the astronauts training base at the Johnson Space Center in Houston, Texas.

“It’s great to be back,” said Kelly to the large crowd of reporters, including me, gathered to greet the crew. “We really appreciate all the hard work by the team that’s worked over the last couple of weeks to get shuttle Endeavour ready. We are really excited to be here, excited to launch, hopefully on Monday if the weather holds.

Kelly is joined on the crew by pilot Greg H. “Box” Johnson and Mission Specialists Mike Fincke, Andrew Feustel, Greg Chamitoff and Roberto Vittori. Vittori is a European Space Agency astronaut and spoke first in his native Italian language and then in English.

“Box” celebrated his 49th birthday today. “I can’t think of a more perfect way to spend my birthday then to come here with my crew a get ready to fly Endeavour next week.”

He also thanked the teams for resolving the APU issues. ”Hats off to Dana Hutcherson and her team for preparing Endeavour for this flow and finally a special thanks to the APU team for all the hard work you’ve done getting us to this point. Kudos for solving it and getting us back on track.”

Kelly and Johnson will fly practice landings in the STA in the remaining days prior to Monday’s launch. The STA is a modified Gulfstream II jet which handles like a space shuttle.

Mission Specialist Mike Finke whipped out a camera and photographed the gaggle of media as we were photographing them – a rare and thrilling experience for all of us. Finke tweeted the photo of us a short time later – and is included here.

Technicians at the Kennedy Space Center have been working around the clock since April 29 to determine the cause of the heater failure and fix the problems. The malfunction was traced to a switch box located in the aft section of the shuttle. Shuttle workers swaped out the ALCA -2 load control assembly box. Then they retested the new unit and qualified it for flight.

Humongous crowds are again expected to travel to prime viewing locations around the Kennedy Space Center and pack the local hotels, roadways and beaches. Flocks of tourists are already arriving in anticipation on Monday’s launch. About 750,00 folks had swarmed to Florida for the April 29 launch attempt.

STS-134 is the penultimate mission in the Space Shuttle Program. The last shuttle flight by Atlantis is expected to occur in early July, but a firm launch date has not yet been set.
