HOUSTON - Two shuttle astronauts ventured outside the International Space Station (ISS) early Tuesday to complete work to install a massive new coolant tank during the third and last spacewalk of their mission.

Discovery astronauts Rick Mastracchio and Clayton Anderson floated outside the station's Quest airlock at 2:14 a.m. (0614 GMT) for their last 6 1/2-hour service call on the space station.

Their first task: Hooking up four hoses to funnel liquid ammonia coolant and nitrogen for the space station's onboard systems.

Mastracchio, 50, tackled the job in short order, even pausing at times while Anderson snapped photos.

"Oh baby, you're going to want to take this one to the grandkids," said Anderson, 51, after taking one particularly picturesque shot.

Final STS-131 Spacewalk Complete
Tue, 13 Apr 2010 05:57:31 AM PDT

The third STS-131 spacewalk ended at 8:38 a.m. EDT, a six-hour, 24-minute outing for Mission Specialists Rick Mastracchio and Clayton Anderson.

The spacewalkers fell behind the timeline when an alignment issue delayed the stowage of the depleted Ammonia Tank Assembly on a carrier in space shuttle Discovery's cargo bay. Some planned tasks had to be deferred. Before wrapping up, the spacewalkers relocated a portable foot restraint and prepared cables on the Zenith 1 truss for a spare Space to Ground Ku-Band antenna, two chores required before space shuttle Atlantis' STS-132/ULF-4 mission in May.

This was the final STS-131 spacewalk, the 236th conducted by U.S. astronauts, and the sixth for both Mastracchio and Anderson. It was the 143rd in support of International Space Station assembly and maintenance, totaling 893 hours, 33 minutes. It was the 115th spacewalk based out of the space station, totaling 706 hours, 18 minutes.

Mastracchio's six spacewalks total 38 hours, 30 minutes and Anderson's six spacewalks total 38 hours, 28 minutes. The pair now ranks 21st and 22nd on the list of cumulative spacewalk time.

NASA Television airs a Mission Status Briefing at 11:30 a.m. with STS-131 Lead Space Station Flight Director Ron Spencer and STS-131 Lead Spacewalk Officer David Coan.


Sorry to be so late with posting my “Launch Report,” but I just got back from my Florida vacation, and this is the first chance I got.

MeteorWayne, this report is sort of lengthy. If you think it belongs somewhere else, go ahead and move it.

My wife and I watched the launch from Space View Park in Titusville, just across the Indian River from the Kennedy Space Center. Even though I have watched plenty of launches on TV, this is the only launch I have ever seen in person, so I didn’t exactly know what to expect, and it was AWESOME! Just an absolutely amazing and thrilling experience.

I picked Space View Park as the viewing location mostly because I was totally unfamiliar with the area and had read online that it was a good place to view from. It was also a convenient point to plug into the ole Garmin. Now that I’ve seen the area, I see there are plenty of places along the river from which to view.

I had read that it’s a good idea to be there a couple hours early, so with a 6:21 am launch, that meant trying to be there by about 4:30 am. We were staying in Orlando, which is about an hour from Titusville, so that meant driving over by at least 3:30 am! Yikes! Instead of getting up in the wee hours, we decided to have a late dinner and drive over after that --- so we ate a pile of Cuban food and then left about 11:30 pm and got there around 12:30 am.

I’m glad we got there early. The parking lot was already full, so we paid 10 bucks to park across the street in a vacant lot --- the money goes to fund a non-profit that maintains a museum at the park. They also broadcast the NASA feed over loudspeakers at the park.

We walked into the park toward the river, came out of a little area of trees into an open area, and we could clearly see the 50-story cube of the Vehicle Assembly Building across the river. To the left and further away, we saw the shuttle gantry. The gantry has little lights on it all the way up, so we could easily see it with the naked eye, even as far away as we were. And the whole thing is bathed in incredibly bright spotlights that shine on the whole structure and then continue upward in a bright V shape of light. From our angle, I could not make out the shuttle itself, even with binoculars. Further to the left there is another tall tower, and I think it must be where they store the water that floods the pad during the launch.

Space View Park was full of people who had staked out their space and were camping out overnight. We set up our own little spot with a few towels we had picked up from the pool concierge at the hotel and smuggled out in a backpack (Sorry about the grass stains, dirt, twigs and burrs, Buena Vista Palace). The ironic thing was that we were paying $150 for a great room with a comfy bed on a night we were sleeping in a park on the cold, damp ground with 300 other people. And there really wasn’t any “sleeping.” We were under a street light, on the hard ground, a little bit chilly, and there was constant activity all around us.



Around 3:00 am, they started the NASA feed over the loudspeakers, which gave a little something to do but made sleep impossible. I kept having some trepidation that something would hold up the launch and it would have to be scrubbed, so it was cool to be able to hear the feed and know everything was going smoothly. At T minus 9, there is the 45-minute hold, and toward the end of the hold there was some kind of a glitch, and they had a No-Go situation for a few minutes. I had a minor heart attack at that point, but the problem was resolved and the count restarted on time.

I think it was shortly after the clock restarted at T minus 9 that we saw the Space Station go overhead. That was not something I had expected. I’ve seen the ISS many times by using Heavens Above to get pass predictions. But it did not even occur to me that with this being a morning launch, the conditions would be IDEAL for seeing the station pass over, and of course it WOULD be passing over just minutes before the launch --- that was the whole reason for the narrow launch window, for the shuttle to catch the station as it went over. It really brought home the physics of the whole thing in a totally amazing and concrete way to see it actually happening.

A minute before the pass, the lights in the park were turned off. At exactly the predicted time, the station came into view in the south west. The moving dot of light arced up and over and passed within just a few degrees of the moon (cool!). It continued in the direction of the launch pad and eventually disappeared in the east. It was just so amazing to think that in a few minutes the shuttle would launch to try to catch up with the space station that had just passed overhead!

About the time the lights went out and the station was going over, people started getting to their feet and getting more and more excited. Everyone had a spot staked out with a blanket or lawn chair, but of course that didn’t last long once everyone was standing, and people started pressing toward the river and jockeying for position. My wife and I moved forward and got a perfect unobstructed view of the river close behind a couple who had lawn chairs at the very front of where you could stand. There were a lot of people with cameras and tripods, and I think unless they were in the very front or up pretty high, some of them had their shots ruined by people crowding in front. I had decided not to mess with the camera during the actual launch, because I figured the nighttime shot would be too hard to get anyway, and I wanted to just experience the moment without fiddling with the camera.

As the countdown got into the final minute, everyone started to get excited and we could hear the crowd winding up.
In the last few seconds we saw the water start to flow under the pad. The main engines started, and we saw the vapor begin to billow. Then the boosters fired, and flame was everywhere! For a second I wondered if something was wrong. Through the binoculars it was almost too bright to look at. As the shuttle started to lift off, the flame pouring out of the boosters got longer and wider. The brightness was amazing! The orange light reflecting off the water in front of us was incredible!

As the shuttle rose higher, we could clearly see the vapor trail extending to the ground. The sun was not up yet, but the sky was beginning to brighten in the east, and we could see the lower portion of the trail silhouetted against the light blue of the horizon. Higher up, the column was illuminated by the rocket itself.

One of the surreal aspects was that all we could hear was the noise of the crowd. I think we were probably about 10 to 12 miles away, so all of this fire and energy that we could see happening right in front of us was totally silent for a long time. At about the time the controller gave the go ahead to throttle up, the first rumble started. I wasn’t sure what to expect, but sort of anticipated a deafening roar. It wasn’t as loud as I thought it might be, but it was deep --- we could feel the powerful vibration, or at least it seemed the way. It also seemed that as the sound got louder the crowd got quieter. There was a lot of cheering at the beginning of the launch, and when the sound arrived there was a lot of excited chatter about that, but soon everyone just settled down and watched. Soon the park was almost silent, except for the distant rumble.

From our vantage point, the shuttle arced up, to the left, and away. Toward the top of the arc, it almost seemed we were looking directly into the engines. We could see the vapor trail begin to diminish and change color to a brighter, whiter shade. As the SRBs separated, we could see the glowing orange/red/purple dots of the SRBs move away from the burning white hot main engines in the center. To see the SRBs required binoculars --- with the naked eye you could not see it at all.

I was surprised at how bright the main engines were. I’ve mostly seen daytime launches on TV, and the main engines always seemed faint and washed out, but now they were extremely bright. My wife described it as sort of a starburst pattern. It was strikingly beautiful. You could clearly see the main engines with the naked eye for what seemed like a very long time.

From our angle, after the SRB separation it looked like most of the vapor trail ended at that point, and the bright dot of the main engines continued on in an arc. It’s sort of a trick or perspective, but as the shuttle continued forward, it almost looked like it was angled downward. There was the bright dot of the engines, and the bluish white vapor of the main engines seemed to spray upwards. I guess it’s just that you are looking at it from beneath the arc, and the vapor trail extends for miles, but it does look odd from that angle.

As the white dot finally faded from view, the very top of the vapor trail was high enough to be in direct sunlight, even though the sun was still well under the horizon. That little puff of vapor glowed bright white.


Moving from the glowing cloud back down the arc, there appeared to be a bit of a gap, and then the darker smokier trail from the SRBs picked up and extended all the way back down to the ground.


By now the sky was getting brighter, and the entire trail was clearly silhouetted against the sunrise.

I figured at this point the show was over, but I was wrong. I got the camera out and started taking pictures of the vapor trails. As the sun started coming up, it just got more and more interesting. As the sun started to hit the different layers of the vapor trail, the clouds of vapor started to glow in spectacular sunrise colors. It’s one of the most beautiful things I’ve ever seen. I guess the wind currents curl and twist the vapor into all kinds of strange shapes, and the trail must extend for miles and miles through different altitudes and different distances from the horizon. Looking at the trail, you would almost think the shuttle had done loops and barrel rolls all the way to orbit. It makes for some very weird and beautiful effects.

Some parts of the cloud were bright white; others were golden; others orange; and others deep scarlet. Sometimes these colors were right on top of each other. Watching this bizarre cloud formation change shape and color was almost as interesting as the actual launch. (Almost, but not quite.) After going back to the car, I continued to take pictures of the vapor trails for probably another half hour or 45 minutes, trying to use the door as a tripod to stabilize the camera. Some of them are pretty good shots.








Eventually the cloud was entirely in the sunlight and not nearly as interesting. We were trapped in the parking lot by a huge traffic jam, so we just curled up in the car seats and went to sleep. An hour or two later we woke up aching and went to get breakfast.

This shuttle launch was one of the most memorable experiences of my life. At this point there are only 3 shuttle launches left before they retire the fleet, so if you haven’t seen one, and you have any opportunity at all to do so, I’d highly recommend it.

Thank you for the report, very good job :cool:

Space Station, We Have a Problem: Stuck Valve Recalls Apollo 13 Anniversary
By Robert Z. Pearlman

posted: 13 April 2010
07:05 pm ET

Forty years after astronauts called down from space reporting, "Houston, we've had a problem," it was Mission Control's turn Tuesday to call up to the crew with a similar but far-less life-threatening call.

Problems with pressurized tanks led to both calls. For the Apollo 13 crew in 1970, it was the explosion of an oxygen tank midway to the moon that required flight controllers on Earth to scramble to save the lives of the astronauts.

For the International Space Station's (ISS) Expedition 23 crew, as well as the visiting shuttle Discovery astronauts, the stuck valve between a newly-installed ammonia tank and a nitrogen tank responsible for feeding coolant to half of the station was causing Mission Control concern but it was not an emergency for the 13 people in space.

I'm glad you enjoyed the report, MW. It was an amazing experience.

I feel really lucky to have been able to see a launch in person. I know that any launch under any conditions is spectacular, but I think I really lucked out and got an especially cool one --- and this was through no clever planning of my own. This launch had some great bonuses, just because of the exact timing. It was dark enough to get all the fireworks show effects of a night launch. But because of the early morning, you could actually see the space station pass, and you also had the noctilucent clouds. Just incredible. Even the space station pass alone was a special one because of the super close conjunction with the moon (People in the crowd were joking, "Hey, look! The Space Station decided to go to the moon instead!). I hope I didn't use up all my good viewing karma in one shot...


Thank you very much MasterComposter. :mrgreen:

I am hoping to go to the STS 132 Atlantis launch next month, but my health is still causing problems, so it now looks as if I cannot travel yet.

If not I will try for the last one, STS 133 Discovery in September. Do not fancy Florida in July so I'll have to give STS 134 Endeavour a miss.

NASA engineers are still perplexed by a stuck valve in the International Space Station's cooling system and may even add an extra spacewalk to fix it to the mission of shuttle Discovery astronauts, who celebrated a much-needed day off in orbit Wednesday while delivering tons of supplies to the orbiting lab.

The stubborn space valve is inside a new ammonia coolant tank delivered to the space station by Discovery's crew during three tricky spacewalks. Repeated attempts to open the valve using commands from Mission Control have been unsuccessful.

SDC : NASA: Extra Spacewalk May be Needed to Fix Stuck Station Valve

HOUSTON - NASA is considering adding an extra day and a fourth spacewalk to the space shuttle Discovery's mission so astronauts can fix a stuck valve that is threatening to shut down half of the International Space Station's (ISS) systems.

The valve, which has been stuck in the closed position since April 8, is part of the space station's new ammonia coolant tank and is needed to regulate the flow of coolant through half of the station's systems.

NASA learned it was stuck Tuesday while attempting to activate the new ammonia tank after it was hooked up by spacewalking astronauts.

Leonardo Move Delayed

Thu, 15 Apr 2010 13:41:45 GMT

The operation to move the Leonardo Multi-Purpose Logistics Module (MPLM) from the International Space Station back to space shuttle Discovery’s cargo bay for return to Earth has been delayed due to a problem with the mechanism that holds the MPLM in place.

Teams are troubleshooting one of the common berthing mechanism’s four control panel assemblies. Until this is resolved, they can’t remove the MPLM. They will continue to troubleshoot the issue until noon EDT today, and then try again tomorrow after late inspection. If the MPLM cannot be removed following late inspection Friday, consideration would be given to adding a day to the mission to try again to remove Leonardo off of Harmony.

Today’s Mission Status Briefing now is no earlier than 11:30 a.m. EDT on NASA Television.

No Fourth Spacewalk Needed; Crews to Finish Unloading Leonardo

Space shuttle Discovery’s seven-member STS-131 crew will begin its day by unloading the last transfer items in the Leonardo Multi-Purpose Logistics Module and then closing the hatches between it and the Harmony node in preparation for its return to the shuttle’s payload bay.

Overnight International Space Station and Space Shuttle mission managers agreed there is no need for a fourth spacewalk to replace the nitrogen tank assembly that has a jammed valve. Station ground teams have determined the station can operate for an extended period of time in the current configuration. The team is continuing to troubleshoot the stuck valve and is looking at options for future replacement of the nitrogen tank assembly should that be necessary.

The stuck valve is in a nitrogen tank assembly needed to pressurize a new ammonia tank installed on the station during this mission’s three spacewalks. It keeps ammonia circulating through radiators that dissipate the heat generated by the station’s electronic systems.

Ground teams were concerned a high beta angle would cause the ammonia in the new tank assembly to expand and exceed the capacity of the radiators without the nitrogen to keep the system circulating. The beta angle – the angle between the sun and the plane of the orbit – is increasing, creating higher temperatures.

Leonardo Move Going Forward

Thu, 15 Apr 2010 16:24:24 GMT

Teams have verified the electrical connections with the Leonardo Multi-Purpose Logistics Module’s (MPLM ) common berthing mechanism’s panel assemblies. They are working on procedures for demating the module from the station if there are no further technical issues. The time of the operation is to be determined.

Transfer of Leonardo to Continue Friday

Thu, 15 Apr 2010 22:57:16 GMT

Leonardo was unberthed at 4:24 p.m. EDT, about seven hours later than planned. The crew then used the station’s robotic arm to maneuver the module into position above Discovery’s payload bay. Leonardo will remain in this “low hover” position overnight, and the crew will spend about an hour and a half finishing the job of using Canadarm2 to latch it in the shuttle’s cargo bay on Friday.

The delay in removing Leonardo resulted in a later-than-planned bedtime for the crew, which will be allowed to sleep in for about an hour later until 1:21 a.m. Friday.

Crews Remove Leonardo from Station

After dealing with a balky set of bolt controllers, the combined crew of space shuttle Discovery and the International Space Station removed the Leonardo Multi-Purpose Logistics Module from its station port Thursday.

The crew closed Leonardo’s hatch at 3:38 a.m. EDT, but put the removal on hold when Mission Control saw unusual readings on the Control Panel Assemblies that operate the 16 remote-control bolts used to secure the pressurized cargo carrier to the Harmony module port.

The crew disconnected and reconnected all 36 of the connectors that provide power and data to the controllers, and in the process found a small pin that had been broken. They secured the pin, which was not part of the electrical connections, with Kapton tape to ensure it did not interfere with the bolts’ operation. Mission Control conducted additional troubleshooting, and the bolts were released at 4:19 p.m.

Leonardo, making is final round-trip to the station before becoming a Permanent Multi-Purpose Module for the station later this year, was unberthed at 4:24 p.m., about seven hours later than planned. The crew then used the station’s robotic arm to maneuver the module into position above Discovery’s payload bay. Leonardo will remain in this “low hover” position overnight, and the crew will spend about an hour and a half finishing the job of using Canadarm2 to latch it in the shuttle’s cargo bay on Friday.

Space station and space shuttle mission managers reaffirmed plans made overnight to forego a fourth spacewalk to replace the nitrogen tank assembly that has a jammed valve. Engineers have decided the station can operate for an extended period in the current configuration. The team continues to troubleshoot the jammed valve and to consider options for future replacement of the nitrogen tank assembly. The tank assembly is used to pressurize and adjust for the expansion and contraction of the ammonia that circulates through radiators to shed excess heat generated by the station’s electronic systems.

The crew was awakened at 12:21 a.m. with the “Theme from Stargate” played for Mission Specialist Rick Mastracchio who is wrapping up his third spaceflight.

The shuttle and station crews went to sleep later than planned after Thursday's delay in removing Leonardo form the International Space Station’s Harmony module.

The STS-131 crew will begin the day by packing the Leonardo Multi-Purpose Logistics Module securely into the shuttle’s payload bay before conducting one last inspection of Discovery’s heat shield.

After that work is complete the astronauts will then use the shuttle’s robotic arm and orbiter boom sensor system to begin inspection of the shuttle’s heat shield.

Leonardo Work and Heat Shield Inspection for Crew

Space Shuttle Discovery’s crew will begin the day by packing the Leonardo Multi-Purpose Logistics Module securely into the shuttle’s payload bay before conducting one last inspection of Discovery’s heat shield.

Using the station’s robotic arm, Mission Specialists Stephanie Wilson and Naoko Yamazaki will lower Leonardo into the payload bay. Pilot James P. Dutton Jr. and Mission Specialists Dorothy Metcalf-Lindenburger and Wilson will then use the shuttle’s robotic arm and orbiter boom sensor system to begin inspection of the shuttle’s heat shield.

Discovery is scheduled to undock from the station on Saturday at 7:52 a.m.

SDC : Astronauts Pack Up Shuttle Cargo Pod, Inspect Heat Shield
By Tariq Malik Managing Editor
posted: 16 April 2010
09:36 am ET

Astronauts on NASA's space shuttle Discovery packed a cargo pod back inside their spacecraft's payload bay Friday and took one last look at their heat shield to look for any new damage.

The astronauts used the space station's robotic arm to return their bus-sized cargo pod Leonardo to Discovery's payload bay as they prepare to leave after more than a week at the orbiting lab.

The shiny cylindrical module delivered more than 8 tons of new supplies, science equipment and other cargo to the space station. It is now filled with trash and unneeded equipment to be returned back to Earth.
