For my farewell from the Cape (for now) and STS 130 coverage, please check out this cool video of the STS 130 Night Landing which took place exactly 1 week ago on Sunday night, Feb 21.

It’s been a pleasure and an honor to work as a team for Universe Today; Nancy Atkinson and Ken Kremer reporting live from the Kennedy Space Center – informing all our readers about the remarkable deeds by the STS 130 and ISS astronauts & cosmonauts. As well as all the hardworking folks at NASA and the ISS partners from ESA, Russia, Canada and Japan without whom nothing would happen.

This home video is taken from the 2nd story of the viewing stand located at the shuttle landing runway, formally known as the Shuttle Landing Facility (SLF). This is as close as any observers are permitted other then a few key NASA runway and photography personal situated slightly closer to the strip.

The video is courtesy of my friend Matt at Spacearium, and shot as Nancy and myself were standing next to him. This is really a pleasure to present to you because its exactly the sights and sounds of what we all experienced – LIVE from KSC !

[/caption]In fact, if you look carefully at the beginning and you’ll see the top NASA Shuttle managers – Mike Moses and Mike Leinbach – standing about 20 feet in front of us just as Endeavour comes into view for touchdown. At the very end you’ll catch a glimpse of us motley (but thrilled) crew of photo journalists.

Here my impressions of the landing:

Despite an extremely poor weather forecast, I witnessed Endeavour’s penultimate trip to space conclude with the exciting Sunday night landing at 10:20 PM EST at the SLF landing strip at NASA’s Kennedy Space Center on Feb 21. The 14-day journey of more than 5.7 million miles brought the astronauts full circle from their pre-launch arrival here on Feb 2 aboard the Shuttle Training Aircraft (STA).

The threatening rain showers scooted by, the winds calmed and the totally socked in cloud deck miraculously thinned out. Amazingly, it turned into a perfect evening for a landing.

Abruptly and with absolutely no forewarning, Endeavour’s twin sonic booms shocked the daylights out of us spectators near the runway, announcing her impending arrival at runway 15 in about 3 ½ minutes. Her sweeping 234 degree left turn approach from the north and above the Atlantic Ocean was fully masked under the cover of darkness until the final moments.

Suddenly, I caught first sight of the swiftly descending and barely visible phantom beauty as she swooped down from the sky at the far end of the runway barely above the tarmac. Only her magnificent fuselage, tail and braking drogue parachute were illuminated. In mere seconds she passed directly in front of us. Her wheels touched down as she sped along and disappeared down the far end of the runway, with just her tail in view at night above the tree line traveling from the northwest to the southeast.

Launch Director Mike Leinbach summed up the sentiments of many, saying “I got to watch a lot of the folks out on the runway tonight just kind of stand there and look up at Endeavour and think about the majesty of that ship and it’s next to last flight. There’s a whole series of ‘lasts’ coming up. The people fall in love with the machines. It’s going to be hard to let them go. But we’ve been given our direction. We’re mature about it and adult about it and we’re professional about it. So we’re going to process and fly that last mission. And move on.”

Only 4 Space Shuttle flights remain in the manifest.

If you can, try and take the opportunity to witness one of the final launches before these magnificently capable vehicles are prematurely retired at the peak of their capability later this year.

During the two week flight, the STS 130 crew brought aloft and installed the Tranquility habitation module and the Cupola observation dome. Tranquility houses critical ISS life support systems. The Cupola possesses 7 spectacular windows and has exceeded its pre-flight billing by affording dazzling vistas of the earth below and the cosmos above.

See my earlier reports for close up photos of Tranquility and Cupola from inside the Space Station Processing Facility.

The station is now 98 percent complete by volume and 90 percent complete by mass. The station itself exceeds 800,000 pounds and the combined weight with the shuttle exceeds 1 million pounds for the first time.

Astronaut Soichi Noguchi, (@Astro_Soichi) who has taken full advantage of being able to use Twitter live from the International Space Station, has been sending down a stream of images he has taken of Chile following the magnitude 8.8 earthquake that hit the country early Saturday. Just recently, he posted the above image, taken directly over Santiago. “Santiago, the capital city of Chile. One day after the Mega earthquake(M8.8) hit the country. We wish the earliest recovery,” Noguchi wrote on Twitter. He also took a video of the ISS astronaut’s view as they flew over Chile earlier today, below.

Here’s another image Noguchi took from the ISS, of the coastline of Chile, near Santiago.

Buy Your Own Space Underwear

[/caption]
Remember the “long duration underwear” tested out by Japanese astronaut Koichi Wakata on board the ISS last year? Now you can buy your very own. The specially designed undies and other clothing called “J-ware” are on sale now for 10,500 yen or about $115 USD. J-ware is treated with antibacterial and deodorizing materials, so they can be worn for long periods of and are resistant to odors. “(For) two months I was wearing these underwear and there was no smell and nobody complained,” said Wakata. “I think that new J-ware underwear is very good for myself and my colleagues.”

Hurry, sizes and quantities are limited.

Here’s the English translation of the J-ware website,
 and the original Japanese version.

In addition to odor control, the clothes are designed to absorb water, insulate the body and dry quickly. They also are flame-resistant and anti-static.

Typically, clothes can only be worn for a few days in space, and especially the clothing worn by astronauts as they exercise. Since there’s no laundromat in space, the clothing is discarded as garbage.

Astronaut Takao Doi, who flew with a shuttle crew in early 2009 to deliver Japan’s Kibo laboratory to the station, exercised as much as his crewmates, but his clothes stayed dry.

Wakata’s clothes include long- and short-sleeved shirts, pants, shorts and underwear. Special socks have a separate pouch for the big toes (see top image) so the astronauts can use their feet like an extra pair of hands, helpful for anchoring themselves on the floor while doing work on the station.

End of an Era: “Lasts” for Shuttle Program

Final test firing of reusable solid rocket motor FSM-17 on Feb. 25 in Promontory, Utah. Image Credit: NASA

[/caption]
Yesterday, NASA’s Space Shuttle Program conducted the final test firing of a reusable solid rocket motor, in Utah. Look to see the words “final” and “last” frequently over the next few months in regards to the space shuttle. “There is a whole series of lasts coming up,” said space shuttle launch director Mike Leinbach at Endeavour’s landing earlier this week, who talked about the “majesty of this ship” and “people who have fallen in love with this machine.” It’s going to be hard to let them go,” he said, “but we’ve been given a new direction and we’ll process that last shuttle and fly that last mission and move on.”

Here’s a few notes and recent news items on the end of the shuttle program:

Some spectacular pictures from the final SRB test. FSM-17, (that’s flight support motor, not Flying Spaghetti Monster) burned for approximately 123 seconds — the same time each reusable solid rocket motor burns during an actual space shuttle launch.

The final test was conducted to ensure the safe flight of the four remaining space shuttle missions. A total of 43 design objectives were measured through 258 instrument channels during the two-minute static firing.
The first test was in July 1977. The motors, built by ATK motors have successfully launched the space shuttle into orbit 129 times – out of 130 attempts.

You can watch the entire test firing video below.

And speaking of the end of the shuttle program, NASA held an in-house competition to design a shuttle commemorative patch, and last week, the winners were announced. They are beautiful designs, so I’ll post the 3 winners.

Blake Dumesnil, a Hamilton Sundstrand camera engineer from Johnson Space Center, designed the patch, above, which was chosen by judges out of the 85 designs submitted by the agency’s past and present workforce.

It shows a launching space shuttle bordered by a US flag and stars to commemorate both NASA’s orbiter fleet and the astronauts whose lives were lost while flying aboard them.

Second place went to Jennifer Franzo from the Michoud Assembly Facility, New Orleans. Her “Mission Complete” logo shows a shuttle in orbit “tipping its wing to the world, as a way to say ‘thank you’ and ‘farewell’ just as a cowboy would wave goodbye into the sunset.”

Third place went to Tim Gagnon, a former subcontractor employee at Kennedy Space Center, Florida, whose patch designs have been worn by the astronaut crews on shuttle and International Space Station flights. His contest entry focused on the “orbiter coming home for a safe landing at the conclusion of its final mission.”

One other news item for one of the final shuttle flights. On STS-133, the second-to-last scheduled shuttle flight, the Leonardo Multi Purpose Logistics Module (MPLM) will be brought up to the ISS to become a Permanent Multipurpose Module (PMM).

Leonardo is currently undergoing processing to bring supplies to the ISS on the STS-131 mission, and I visited the Space Station Processing Facility last week to view the module up close. After returning home from this mission, Leoardo will undergo modifications to ensure safe, long-term operation as the PMM, and to increase the amount of mass it can carry to orbit.

Inside the PMM, experiments in fluid physics, materials science, biology, biotechnology and other microgravity experiments may be conducted.

MPLM’s have been flown inside the payload bays of the shuttles, successfully delivering vital hardware and supplies to the station. The new use for this proven carrier will provide more room and enhance the use of the station.

As promised, here’s the video of the SRB test:

ISS Astronaut Captures Shuttle Landing from Cupola

ISS astronaut Soichi Noguchi has been sharing lots of amazing pictures he’s taken in space via Twitter, but this one is extra special. Noguchi was able to capture the plasma trail produced by space shuttle Endeavour as it streaked through Earth’s atmosphere. “Space Shuttle Endeavour making S-turn during atmospheric re-entry,” Noguchi wrote on his Twitpic page, where he post his space photos from Twitter, @Astro_Soichi. “The first time it was photographed from Space Station Cupola. Priceless.”

Just think of the precision it took to be able to take this image. Noguchi and the space station were flying about 354 km (220 miles) above Earth, going about 28,163 kph (17,500 mph), and the shuttle was likely flying just under Mach 25 — the speed it is going as it enters Earth’s atmosphere. Priceless indeed!

Endeavour Comes Home to Kennedy Space Center

Space shuttle Endeavour loudly announced its arrival with twin sonic booms, then two minutes later emerged like a phantom out of the darkness to touch down beautifully on runway 15 at Kennedy Space Center. The landing at 10:20 p.m. EST Sunday ended the two-week STS-130 mission to the ISS. After early concerns about the weather, conditions were almost ideal for landing.

“STS-130 is mission complete, and we’re safe on deck” said Commander George Zamka, speaking on the runway after the crew disembarked from Endeavour. “The Cupola is beautiful in both design and function, and Endeavour was perfect throughout the flight… Now it’s time for us to hit the showers and get used to life on Earth again.”

“It was really exciting to land on the first opportunity,” said astronaut Bob Behnken, “and we’re happy to put this capstone on such a great mission.”

The STS-130 crew delivered the “room with a view” to the ISS – the Node 3, or Tranquility module with the attached Cupola that will provide astronauts with 360 degree views of Earth, space and robotic operations outside the space station.

At the post-landing press conference, mission managers echoed the astronauts’ sentiments.

“It was a fantastic landing day, and Endeavour’s landing here tonight at KSC capped off a perfect mission on orbit,” said Mike Moses launch integration manager for the space shuttle program. “The vehicle performed absolutely flawlessly, the crew did outstanding job,… the installation of Node 3 and Cupola all went perfectly. This just illustrates the great job the all the teams did. Just a spectacular mission.”

Space shuttle launch director Mike Leinbach also looked to what is ahead for the space shuttle program.

“One of the most magical things we get to do here is to walk around the space shuttle on the runway after a mission,” he said. “The shuttle looks outstanding out there, and we’re going to start the final processing flow of Endeavour tonight. So that will be a milestone for the space shuttle program, and we will go into that with our heads held high and we’re going to process the vehicle as we always do and be ready to fly her last mission. A little bit of a sad note, but a great ending to a great mission and we’re looking forward to the next one.”

With this mission the ISS is now 98% mass complete.

Next up for the shuttle and ISS programs is Discovery’s STS-131 mission, currently slated to launch on April 5, 2010.

While this marks the end of this mission — which Ken Kremer and I have been reporting on live from KSC — I will still be hanging around the Space Coast for a few more weeks, so look for more news (and launches!) coming up. And we hope to have photographer Alan Walters on location at KSC for Universe Today covering the final flights of the space shuttle program.

Multiple Computer Failures on the ISS

[/caption]
The main computer on the International Space Station failed early Sunday, and subsequent multiple computer anomalies prompted communication blackouts. The one main computer has two backup systems, and NASA reported that the three command & control computers are switching between prime, backup and standby. A software issue is suspected, and diagnosis continues. The computer system is critical to all aspects of space station operation.

NASA reported that despite the computer issues, all ISS systems are performing normally and there are no concerns for the safety of the crew.

Bill Harwood at CBS News reported that the station’s command and control software was updated before the shuttle Endeavour’s flight to account for the new Tranquility module and it’s possible the computer failures, or transitions, are software related. Issues with computers in Tranquility also have been noted, but it’s not yet clear whether they are related to the command and control issues.

ISS Commander Jeff Williams called Mission Control at 9:55 a.m. EST “and confirmed there had been a primary and backup failure of the command and control computer,” said NASA TV commentator Pat Ryan. At that time, all indications were that two of the three computers were healthy. But then later, about 11 a.m. EST, there new data indicated there had been another computer transition, this time still with just two computers healthy.

Another transition occurred an hour later.

“But we are still in a situation currently where all three computers are healthy but the team here in mission control is still scratching its head and trying to determine what’s been causing the repeated transitions,” Ryan said. “There has been no impact to station life support systems while this was going on and the crew is in good shape.”

“We’re thinking we might need another day off,” said Williams, apparently in good spirits.

“Copy and concur, Jeff,” replied Stan Love in Houston. “We are talking in the room, we still do not know what has been causing these transitions. We are toying with the idea there might be something related to commanding. But we are not sure, it’s just speculation at this point.”

Endeavour Crew Preps for Sunday Landing as Showers Threaten Delay

The crew of Endeavour is packing up their gear in the crew cabin and preparing for a Sunday evening (Feb. 21) landing at the Shuttle Landing Facility at the Kennedy Space Center (KSC) in Florida as a forecast of possible rain showers threatens to delay their return to Earth.

The first landing attempt is set for 10:20 PM EST on Orbit 217 with the de-orbit burn planned for 9:14 PM. See landing track below. A second opportunity is available at 11:55 PM. There are two additional opportunities available overnight at Edwards Air Force Base, Calif., at 1:25 AM EST Monday and 3:00 AM. The Spaceflight Meteorology Group and local news forecasts here in Florida predict deteriorating weather at KSC on Monday with increasing chances of rain.

The crew will berth the robotic arm and conduct the standard pre-landing check out of re-entry systems for the flight control surfaces. They will test the hydraulic power units and elevons and test fire all the steering jets during their last planned full day in space.

Eight Xenon lights will illuminate the SLF for the night time shuttle landing. Four xenons will be positioned at both ends of the runway to illuminate the touchdown and rollout area from behind the shuttle. Each Xenon light emits 1 billion candlepower, or 20 kilowatts.

Endeavour undocked from the ISS on Friday (Feb 19) at 7:54 PM EST while orbiting 208 miles high above the Atlantic Ocean after a completely successful period of joint operations with the Expedition 22 crew totaling nine days, 19 hours and 48 minutes. Shuttle pilot Terry Virts performed a fly-around of the station, enabling his crewmates to conduct a photo survey of the complex. The crew also conducted the now standard final check for any signs of damage to the heat shield tiles on Endeavour’s belly and the reinforced carbon carbon (RCC) panels on the wing leading edges and nose cap using the Orbiter Boom Sensor System attached to the shuttles robotic arm in order to ensure a safe reentry.

During the two week flight, the STS 130 crew brought aloft and installed the Tranquility habitation module and the Cupola observation dome and conducted three spacewalks. Tranquility houses critical life support systems. The Cupola possesses 7 spectacular windows affording dazzling vistas of the earth below and the cosmos above.

The station is now 98 percent complete by volume and 90 percent complete by mass. The station itself exceeds 800,000 pounds and the combined weight with the shuttle exceeds 1 million pounds for the first time.

What’s the Internet Really Like in Space?

The space chicken seen in the STS-130 execute packages.

[/caption]
With the internet now part of daily life on the International Space Station, inquiring minds want to know! Can astronauts visit any websites they want, and what kinds of download speeds do they have in space? And what about that chicken, seen above, that has been gracing the STS-130 execute packages? And what’s the view from the new cupola really like? Astronauts answered those questions and more, at the joint crew news conference last night, where I had the chance to talk the crew members of Endeavour and the ISS.

“Thanks for asking about the internet!” replied ISS astronaut T.J. Creamer with a laugh. “This is a project that many people have worked on to make this possible for us, and some have pulled their hair out to make it successful, so many thanks to those folks. We have access to any website we are allowed to go to as government employees – that’s my best answer! And in terms of download speeds – you know, back in the old days, it kind of compares to 9.6 and the 14.4 kilobyte modems, so it’s not really fast enough to do large file exchange or videos, but it certainly lets us to do browsing and the fun reading we want to do, or get caught up on current events on that day. It’s a nice outreach for us, and of course you’ve heard about the Twittering which is a nice feature that we can partake in also.”

Later, Soichi Noguchi said he could keep up with results of the Olympics just like those of on the ground. Noguchi has been taking advantage of Twitter by sending several Twitpics from space.

The personal web access on the ISS takes advantage of existing communication links to and from the station provides astronauts with email, texting, Twittering and other direct private communications, which NASA says will “enhance their quality of life during long-duration missions by helping to ease the isolation associated with life in a closed environment.”

As for the chicken on the STS-130 execute packages, the STS-130 crew was perplexed. “That is possibly an inside joke that we are not on the inside of,” answered Commander George Zamka. “We don’t see the front pages, so it’s probably on the front pages of the execute package that we don’t get.”

You can see the STS-130 execute packages (and chickens) at this link.

Asked about the views from the new cupola, the astronauts waxed poetic. “It’s so hard to put into words the view that we see out those beautiful seven windows,” Kay Hire said. “It’s like comparing a black-and-white analog picture to a super high-def color picture. It’s just phenomenal what we can see out there. The most stunning thing I’ve seen so far is just some beautiful thunderstorms from above. It’s really interesting to watch the way the lightning jumps from cloud to cloud far below us.”

“Getting to look out the shuttle windows and the station windows has been awesome,” added pilot Terry Virts. “But when we looked out the cupola, it’s impossible to put into words, but it took my breath away. We’ve only had a few opportunities to go down there because we have been busy inside doing work, but I think the favorite view that I’ve had has been watching a sunrise.

“At night, you can see cities if you’re over land and then when you pass into the sunlight you get the blue limb (of Earth) and then it turns into pink and different colors like that and then when the sun pops up, it’s like an instantaneous floodlight in your eyes, it kind of overwhelms you. But the view is amazing. You can sit there and perceive the entire Earth limb and you can really see the Earth has that round shape. It’s just amazing.”

ISS Commander Jeff Williams agreed. “To be able to see the entire Earth in one glance and see the entire limb of the Earth all the way around and see the spherical shape of the Earth is going to be new to us. Obviously, we’ve seen a lot of those segments of that view before, but only one segment at a time through a narrower field of view,” he said. “We have taken a lot of photography up here, we will continue to do so. The cupola will offer us a very unique and new opportunity for photography in a new way, particularly with wide angle lenses, which we’re already playing with a little bit to try to be able to share that experience with folks on Earth.”

Spacewalker Bob Behnken said the view from the cupola was as good as or maybe better than the view from a being out on an EVA.

“The reason being you actually have time to look around through all the windows,” he said. “Usually during a spacewalk, there’s a fair amount of work to get done. There wasn’t a lot of time for the sightseeing you might like to do out of a window like cupola.

“The other thing the cupola affords you is the opportunity to share some of those views with other people. We’re really limited on the photography we can do during a spacewalk, but taking one of the HD cameras or some still photos inside the cupola is really going to allow us to share those beautiful sunrises and sunsets and Earth views in general with everyone on the ground.”

Double Spaceship Sighting Alert!

Space shuttle Endeavour will undock from the ISS on late Friday (7:54 p.m. EST) or early Saturday (00:54 GMT) depending where you live, providing an opportunity to see the two spaceships flying in tandem. This is an incredible sight, and as the shuttle program comes to a close, one that will happen only about four more times. Early morning sightings are favored for those in the northern hemisphere. The two spacecraft will be seen as separate but closely-spaced points of light. The ISS is bigger, so will appear as the brighter object trailing the smaller Endeavour as they move across the sky. Double flybys will continue until the shuttle lands, currently scheduled for late Sunday or early Monday, with the two getting farther apart each day. Of course, your viewing ability will depend on cloud cover. Above, you can watch the ceremony as the shuttle crew returned to Endeavour and closed the hatches from the ISS.

To find out if you’ll be able to see spaceships in your area, there are a few different sites to check out:
