Great Images From the STS-123 Mission

There have been some outstanding images coming in from the current space shuttle mission at the International Space Station. The crews of Endeavour and the ISS continue their near-frantic pace of spacewalks and outfitting of the station during the STS-123 mission. During the 3rd spacewalk, astronauts Rick Linnehan (right) and Bob Behnken work on the new Dextre, also known as the Special Purpose Dextrous Manipulator (SPDM). This image highlights how big the station is getting, as the astronauts are almost dwarfed by this one area of the truss section.

Bob Behnken continues his work on Dextre during his EVA. During the 6-hour, 53-minute spacewalk, Linnehan and Behnken installed a spare-parts platform and tool-handling assembly for Dextre. They also checked out and calibrated Dextre’s end effector and attached critical spare parts to an external stowage platform. The new robotic system is scheduled to be activated on a power and data grapple fixture located on the Destiny laboratory today.

Can you imagine looking out a window and seeing one of your best friends floating by? Visible through a window on Endeavour’s aft flight deck is astronaut Rick Linnehan during spacewalk #3 for the mission.

For Wednesday, the astronauts are scheduled to take a half-day off to rest up for two more spacewalks. They also are continuing their work to outfit the Japanese module that was attched to the Harmony node earlier in the mission. They’ll do a round of media interviews this evening, and get ready for another spacewalk on Thursday.

Heavy ATV Must Learn to Apply the Brakes Before Docking with the ISS

atv_docking.thumbnail.jpg

Although ESA’s Automated Transfer Vehicle (ATV) will be approaching the International Space Station (ISS) at a rate slower than tortoise-pace, what would happen if the 20 tonne space truck didn’t slow down as it docks with the station? It wouldn’t be pretty. In all likelihood, the large mass of supplies and metal would cause significant structural damage to the ISS and could be life-threatening to the astronauts on board. To avoid a very big dent in the manned outpost, the ESA’s partners insist that the ATV carry out some practice runs of the Collision Avoidance Manoeuvre (a.k.a. the “emergency brake”)…

The ATV “Jules Verne”, still sitting in an orbital holding pattern awaiting the departure of Space Shuttle Endeavour from the ISS, still must prove its robotic worth. The unmanned supply vehicle is the most advanced spaceship the ESA has ever launched into space and it appears to be performing well. Recent engine problems were quickly and neatly solved and the re-supply mission of the ISS appears to be progressing nicely.

Worked into the schedule of the ATV’s orbit of Earth are some practice manoeuvres – after all, the robot has a lot of time on its hands, a bit of activity should be welcomed.

First up is the spaceship equivalent of an emergency brake. The ATV project will have never been allowed near the space station without an emergency procedure should there be a problem during docking. Although the relative speed between the station and approaching ATV will be exceedingly slow, the orbital velocity of both will be approximately 27,000 km/h, so any unforeseen collision or misalignment could be highly dangerous.

So, the Collision Avoidance Manoeuvre will be carried out on Friday, before the ATV is anywhere close to the station to make sure the operation is successful at preventing a mock collision.

The ATV carries countless failsafe measures; critically the robot runs three parallel flight-control computers with an independent computer overseeing them. If something should go wrong, the flight-control computers can be overridden and an avoidance manoeuvre enacted. Also, mission control in Toulouse, France can manually initiate the Collision Avoidance Manoeuvre and so can the ISS astronauts inside the docking module watching events as they unfold. A big red button has even been installed in the Russian Zvezda module to raise the alarm and force the ATV to stop and reverse at 5 km/h.

The astronauts do it by hitting a big red button on a panel positioned in the Russian Zvezda module.

Relief as Automated Transfer Vehicle (ATV) Propulsion System is Fixed

atv_to_iss.thumbnail.jpg

Problems struck the brand new ESA Automatic Transfer Vehicle (A T V) at 260km above the Earth shortly after it was launched into orbit on Sunday. Seven of the 28 attitude control jets and a main engine shut down unexpectedly, forcing the craft to switch to backup systems. The panic has now subsided as commands sent from mission control fixed the glitch and the thrusters switched back online…

Although the ATV has to wait around for NASA’s STS-123 mission to complete after it un-docks with the International Space Station (ISS) in a few days time, “Jules Verne” still has some manouvering to do. After its launch on board an Ariane-5 rocket from South America on March 9th, all systems appeared to be functioning normally. However, problems struck as the ATV began to thrust its way from its original 260km orbit to the ISS orbit of 340km.

ATV project manager John Ellwood gave a statement in Kourou as the troubles surfaced, but appeared undaunted by the problem:

We’re sitting and thinking about this; we’re not in a rush to do manoeuvres […] We have the 10-day margin before we need to start going into [demonstration manoeuvre] days at the end of the month.”

After all, the ATV has over three weeks to stay in orbit and wait for Space Shuttle Endeavor to leave on March 24th and then dock at the station on April 3rd. Mission engineers had a lot of time on their side. It appears that they only needed a few hours to iron out the problem; all systems appear to be functioning well as of March 12th after new commands were transmitted from mission control.

It appears the problem started after data was received on the ground indicating there was a large difference in pressure between the oxidiser and the fuel entering the ATV’s complex network of pipes and valves connecting the fuel tanks and thrusters. Reacting to the warning, the chains of pipes were shut down, stopping fuel from entering the thrusters. The problem was solved by slowly turning on fuel supplies to each thruster and one of the main engines. The fix appears to be a total success.

The ATV will now carry out practice manoeuvres to prepare it for the ISS docking sequence at the start of next month.

ESA Automated Transfer Vehicle Blasts Into Space (Video); See the ATV Mission Animation

missionup_8march09_lg_6.thumbnail.jpg

The European Space Agency’s (ESA) Automated Transfer Vehicle (ATV) has been successfully launched into orbit. The ATV, also known as “Jules Verne”, is Europe’s largest and most complex spaceship ever. Weighing in at 20 tons, the ATV needed a big push to get it into space, so the largest member of the Arianespace-built rocket family was called into use, the Ariane-5. The unmanned ATV is now en-route to the International Space Station, to make some deliveries…

(Including a cool little animation of the entire mission courtesy of ESA.)


Launched from French Guiana (South America) at 0403 GMT, March 9th, the Ariane-5 rocket lifted the heavy vehicle into orbit to send cargo, propellant, water and oxygen to the International Space Station (ISS). This is the largest payload ever lifted by Arianespace, and the new Ariane-5 performed excellently. After 66 minutes from blast-off, the launch was declared a success as the ATV separated from its Ariane-5 boosters to begin its mission.

The ATV is a unique spacecraft. It has been called a “barge”, “truck”, “freighter”, “tug” and its mission is pretty unglamorous. Primarily it will take about 7.5 tons of supplies to the ISS, docking (automatically) with the Russian service module. Then, it will act as a waste disposal module for six months, remaining attached to the station, being filled with rubbish from the stations crew. When full with over six tons of trash, it will separate and then kill itself by falling through the Earth’s atmosphere, insuring all the waste gets incinerated. It will be the ultimate single-use product.

The ATV now has to hang around in an orbital holding pattern to wait for Space Shuttle Endeavour to launch (on March 11th), dock and then leave the ISS on March 24th before it can approach the station. See “Traffic Jam at the Space Station” to find out how busy it’s getting up there.

First Experiment Starts in ISS Columbus Module Testing Plant Growth

01_arabidopsis_large0.thumbnail.jpg

The brand new ESA Columbus Module installed on the International Space Station (ISS) by the STS-122 crew last week is beginning a first run of biological experiments. This first experiment tests the reaction of root growth in different gravitational states. Of particular interest is how the roots of seeds develop in space when compared to terrestrial conditions. This has obvious applications for growing plants in space, underpinning agricultural science in some of the most extreme and challenging environments man will experience.

Today saw the first ever experiment on the ESA Columbus Module on board the ISS. European astronaut Léopold Eyharts activated the Waving and Coiling of Arabidopsis Roots at Different g-levels (WAICO) experiment, comparing two types of arabidopsis seed (one wild and one genetically modified) in gravity conditions from zero to one Earth gravity (or 1G). The arabidopsis seed is derived from the arabidopsis thaliana plant which copes very well in restricted space and thrives in hostile surroundings.

The WAICO experiment will last for 10 to 15 days and the sprouted seeds will be returned by the STS-123 Space Shuttle mission due for launch on March 11th so the results can be analysed. Throughout the experiment, using the brand new “Biolab” equipment (pictured), the advanced telemetry of the Columbus Module will relay real-time video of seed development to ESA scientists in Germany.

The development of the root growth will be scrutinized; especially the amount of “waving” and “coiling” that occurs as a reaction to different gravity conditions. These experiments will also help terrestrial farming methods, giving farmers the opportunity to optimize plant growing conditions.

Shuttle Endeavour to Launch on March 11th; View the STS-123 Interactive Mission Timeline

We haven’t had time to catch our breath after STS-122 touched down on February 20th, only nine days ago, and yet the next launch date to the International Space Station (ISS) has been announced today. The date? March 11th - only 11 days from now. This time NASA has put together a nice little interactive gadget so you can see the 17 day mission from day to day…

STS-122 was a highly successful round trip to the ISS. The Space Shuttle Atlantis crew delivered ESA’s Columbus science module without a hitch on February 11th. The only small problem arose when one of the crew members suffered an undisclosed minor medical problem, postponing installation for a day, but the crew adapted and performed excellently.

With Atlantis’ engines still warm, Endeavour is being prepared for launch on March 11th. This time the mission is to install a part of the Japanese laboratory complex called “Kibo”. In addition, a new Canadian robotics system will be attached to complement the existing robotic arm servicing the Harmony module.

STS-123 will be a complex mission for crew members Dominic Gorie (Commander), Gregory H. Johnson (Pilot), Rick Linnehan (Mission Specialist), Robert L. Behnken (Mission Specialist), Mike Foreman (Mission Specialist), Garret Reisman (Mission Specialist) and Japanese astronaut Takao Doi. Five spacewalks (EVAs) will need to be carried out to continue the expansion of the station.

The Associate Administrator for Space Operations, Bill Gerstenmaier, stated that there were very few issues with the pre-launch stages and said that Space Shuttle Endeavour is ready to blast off.

Shuttle Crew Says Goodbye, Undocks from ISS

212265main_image_1021_800-600.thumbnail.jpg

After a successful visit to the International Space Station, the crew of space shuttle Atlantis said farewell and undocked from the station at 4:24 am EST Monday morning. Their busy nine-day stay included three spacewalks and the installation of the European Columbus science module, as well as a switch-out in crew. European astronaut Leopold Eyharts stays on the ISS while US astronaut Dan Tani returns home after a four-month expedition on the station.

“We just wanted to thank you again for being a great host and letting us enjoy your station for about a week,” shuttle commander Steve Frick radioed to the ISS before undocking. “We had a great time over there, we learned a lot and we really, really enjoyed working with your crew, one quarter of which we have here and we’re happy to take Dan home. But just again, to you and to Yuri and to Leo, thanks very much.”

“Well thank you guys,” station commander Peggy Whitson replied. “It’s a great new room you’ve added on and we really appreciate it. Get Dan home safe, and thanks!”

In an emotional farewell ceremony on Sunday, Tani reflected on his extended mission. The delay of Atlantis’ mission due to fuel sensor problems made his stay in space almost two months longer than originally planned. During his time on the station, Tani’s mother, who he called his “inspiration” was killed in a car accident. He said he can’t wait to get back home to be with his family.

But his recent experiences have given him great hope for the future.

“Today I feel very optimistic about our space program and our society because I’m here, I’ve spent time with a man from France, from Italy and from Germany and from Russia,” he said. “Nations that have not always been friendly are now cooperating and we’re doing great things.”

With shuttle pilot Alan Poindexter at the controls, the shuttle did a one-loop fly around of the station before departing. Atlantis’ crew is inspecting the shuttle’s heat shield to get the final OK for landing, which is scheduled for shortly after 9:00 am Wednesday morning, if the weather holds in Florida. Both the Kennedy Space Center and the backup landing site in California will be ready as NASA wants the shuttle to land that day to give the military enough time to destroy a damaged spy satellite.

The next shuttle flight is coming right up. Endeavour began its crawl to the launch pad early Monday in to prepare for a March 11 liftoff.

North American residents with clear skies Monday evening should be able to see both Atlantis and the ISS flying in tandem. See NASA’s orbital tracking site or Heaven’s Above for sighting times for your area.

I Heart the ISS: Ten Reasons to Love the International Space Station

The International Space Station. Image Credit: NASA

It’s been called a white elephant, an orbital turkey, a money pit, and an expensive erector set. Seemingly, there’s even people at NASA who think building it was a mistake. The International Space Station has been plagued with repeated delays, cost overruns, and bad press. Additionally, the ISS has never really caught the fancy of the general public and most likely there’s a fair percentage of the world’s population who have absolutely no idea there’s a construction project the size of two football fields going on in orbit over their heads.

But I’m going to be honest. I’ll come right out and say it: I really like the ISS. In fact, I’m crazy about it, and have been ever since Unity docked with Zarya back in 1998. Yes, my heart belongs to the space station, and since its Valentine’s Day, I’m going to profess my feelings here and now with ten reasons why I love the International Space Station:
(In no particular order:)

1. International Cooperation. Didn’t your heart swell with pride for the Europeans when the Columbus science module finally became part of the station this week? And you gotta love the Canadians for their reliable, heavy-duty Canadarm 2. The Russians have been steady partners in station construction and re-supply for years now. Japan’s science lab will be added on the next shuttle mission.

The ISS is the largest, most complex, international engineering project in history. In a world where violence and political animosity floods the daily news, it’s incredible that this structure is quietly being built by 16 different countries working together in relative harmony. If not for the international partners, the ISS probably wouldn’t have gotten off the ground. NASA Administrator Mike Griffin has said that the station’s most enduring legacy is the international partnership that created it.

2. Actually Building an Outpost in Space. The dream of almost every post-Apollo space enthusiast is to have a settlement or colony in space. As humble as it is, the ISS is exactly that. Humans have been living on board the station for over 7 years now. The experience of constructing and living aboard this complex structure in space is invaluable, and any future outpost will benefit from what’s been learned with the ISS.

3. The Personalities. Peggy Whitson, the first female station commander. Clay Anderson’s unique sense of humor. Suni Williams’ marathon and haircut for cancer patients. Mike Lopez-Alegria’s music. Mikhail Tyurin’s golf shot. Yuri Malenchenko’s wedding. Frank Culbertson’s September 11 perspective. Yury Usachev’s spinning antics. It goes all the way back to the three-way fist pump on Expedition One between Bill Shepherd, Sergei Krikalev, and Yuri Gidzenko. With the Expeditions lasting 4-8 months, we have the opportunity to get to know the astronauts and cosmonauts that live and work on board the ISS. If you watch the daily feeds from the ISS or listen to the periodic press conferences, you can become familiar with the different personalities of the station crews. The number one personality has to be Don Petit and his Saturday Morning Science.

4. You can see it almost every night. I’ve witnessed jaws dropping and eyes widening in wonder when people see the ISS for the first time gliding silently and swiftly across the night or early morning sky. I never tire of observing it. Find out when the station will fly over your backyard at NASA’s website or at the Heaven’s Above website.

5. No major problems so far. One of the real impressive things about the ISS is that all the components, built by different countries and contractors have fit together perfectly. Yes, there have been intermittent computer issues, a faulty smoke alarm and the torn solar arrays. But these problems have all been resolved in short order. The damaged SARJ (Solar Alpha Rotary Joint) is a looming issue that could be problematic. But there are some first-rate engineering minds working on this matter, and it appears they have time to come up with a solution. The station has never had a major calamity or had to be evacuated in over 7 years of continuous human occupation. Knock on a Whipple Shield.

6. The general public can participate. Schools and informal education centers can conduct live question and answer sessions with space station crews. Middle school students can choose locations on Earth for the ISS crew to take pictures as part of the EarthKAM project. Ham radio operators can talk regularly with astronauts and cosmonauts with the ARISS (Amateur Radio on the ISS.) College students can design projects to be researched on board the station. And of course if you have $40 million in spare change you can ride to the ISS on a Soyuz as a spaceflight participant.

7. Finally, we have science officers. The other dream of every post-Apollo space enthusiast (and Star Trek fans) is to have science officers to conduct real scientific research. The ISS has had science officers since 2002, but science hasn’t been in the forefront of the work on board the ISS. Yet.

8. Long term research. The ability of the ISS to serve as a platform for science has come under fire. But what other lab has been expected to produce scientific results while still under construction? With the addition of the European and Japanese science labs, and the expected increase in crew size from three to six in 2009, scientific research, the original purpose of the station, will finally be able to be conducted with consistency. The microgravity environment of the ISS allows the study of long-term effects of weightlessness on the human body, crucial for any future human exploration on the moon and Mars. Research will help fight diseases such as diabetes, cancer, osteoporosis, and AIDS. The station provides a unique place to test technologies such as life support systems and new manufacturing processes, and gives us a long-term platform to observe and understand Earth’s environment and the universe.

9. Post docking fly-arounds. After each construction mission to the ISS, the shuttle’s post docking fly-around gives us a chance to see the new additions and latest configuration of the station. The astronauts say it’s a thrill to see how their handiwork on a specific mission fits into the big picture of the entire ISS, and it’s a thrill for us back on Earth to see the station’s new look, too. Plus the fly-around usually gives the shuttle pilot some actual stick time to fly the shuttle and a little time in the limelight.

10. What else would we be doing? Some people feel that the ISS’s tremendous budget has taken funds away from robotic exploration and other science. I can’t argue with that. But when it comes to human spaceflight, what else would we have been doing for the past 10-20 years? A space station was the logical next step after the shuttle. The main problem is that it took so long to decide on a plan, get it approved by Congress and get it in the works with international cooperation. But now, with construction and maintenance ongoing, we’re constantly and continually learning how to live and work in space. The ISS is a resource that will guide us on our future human endeavors in space. It’s more than just an obligation to finish and then be disregarded. The planning and funding for its future should encompass the maximum utilization of its fullest potential.

In my eyes, the International Space Station is a thing of beauty, a work of art, an engineering marvel, and a constant companion that I watch for every night as it orbits our planet. The ISS should be given all the respect — and love — it deserves.

Columbus Module Attached to ISS after Eight Hour Spacewalk

211186main_columbus.thumbnail.jpg

The ESA Columbus module is now attached to the Harmony module on the International Space Station after a successful spacewalk by Space Shuttle Atlantis crew members Stan Love and Rex Walheim. Although Columbus installation was postponed for a day, today’s (Monday) spacewalk was completed in 7-hours and 58-minutes, concluding at 5:11pm EST.

The European Columbus space laboratory has been successfully attached to the Harmony module on the International Space Station. Although the mission took longer than expected, almost eight hours, the spacewalk appears to be a resounding success. Sunday’s planned effort to unpack and attach the module had to be postponed due to an undisclosed medical problem with German astronaut Hans Schlegel. Americans Stan Love and Rex Walheim took over today, probably much to the frustration of Schlegel who had to watch events from inside the station. The medical problem is said not to be serious.

Walheim: “Welcome to spacewalking, buddy.”
Love: “It’s awesome.”
– Communication between the two astronauts as Stan Love embarked on his first ever EVA on Monday.

It’s not all bad news for Schlegel, he is expected to assist in a spacewalk on Wednesday to continue the installation.

In today’s successful docking of Columbus, the first task was to prepare the Power Data Grapple Fixture on the module so the ISS could capture it with its robotic arm. The arm was operated today by astronaut Leland Melvin, former wide receiver in the US National Football League, and the 12.8 ton module steered to its new home as an extension of the space station. In addition to this, the astronauts prepared for the removal of the Nitrogen Tank Assembly (NTA), a component in the station’s thermal control system. The next spacewalk on Wednesday will install a new assembly after removing the old one. This task had to be carried out as the existing NTA was running low of nitrogen.

Video of Space Shuttle Atlantis (STS-122) Pitch Maneuver Prior to ISS Docking

shuttle_pitch.thumbnail.jpg

In a superb video released by NASA, the Space Shuttle Atlantis’ 360 degree pitch maneuver is captured prior to docking with the International Space Station (ISS) on Saturday. Atlantis’ mission to the station is to deliver and install the European Space Agency’s (ESA) Columbus science laboratory to the station tomorrow (Monday) despite the first spacewalk being postponed due to an undisclosed medical problem with one of the STS-122 astronauts, Hans Schlegel.

It is always amazing to witness the Space Shuttle in Earth orbit, especially when carrying out docking maneuvers or maintenance tasks. With the help of the crew on-board the ISS in the Russian Zvezda service module (pictured), Space Shuttle Atlantis’ rendezvous pitch maneuver (RPM) is videoed before the shuttle began its final approach to the station yesterday (Saturday). The maneuver, where Atlantis performs a “backflip” at a rate of three quarters of a degree per second, exposes the shuttle’s heat shielding on its underside. The ISS crew could then take a series of high-definition photographs to see if there was any damage to the protective layer.

A small protrusion of Atlantis’ thermal blanket was discovered on Friday (8th Feb.) during a standard arm checkout and payload bay survey (pictured), but it is not believed to be a problem after the more detailed survey from the RPM.

Space Shuttle Atlantis finally made it into space after a series of delays. It was launched on Thursday (7th Feb.), and you can see the launch in another NASA video (from lift-off to booster rocket separation). Always exciting to watch…

The new Columbus module will be prepared for installation at 9:35am on Monday by Mission Specialists Rex Walheim and Stanley Love during a space walk. Their first task will be the installation of the Power Data Grapple Fixture on the new module, allowing the ISS robotic arm to grab the laboratory and position it at the station’s Harmony module. We will be watching the events as they unfold…
