Space Station Crew Vehicle Move for Cargo Ship Arrival

Space Station Crew Vehicle Will Move June 28 for Cargo Ship Arrival

HOUSTON -- NASA Television will broadcast live the repositioning of a Soyuz spacecraft docked to the International Space Station on Monday, June 28. The capsule’s half-hour journey from the Zvezda Service Module to the Rassvet Module will begin at 12:58 p.m. CDT.



Expedition 24 Flight Engineer and Soyuz Commander Fyodor Yurchikhin and NASA Flight Engineers Doug Wheelock and Shannon Walker will board the Soyuz TMA-19 vehicle that docked to Zvezda on June 18. They will fly the Soyuz vehicle a short distance to Rassvet. NASA TV coverage of the event will begin at 12:30 p.m.

The change of location will free the Zvezda port for the docking of a new Progress resupply vehicle on Friday, July 2. That port is the preferred location for the Progress, so it can help reboost the station and adjust its altitude. The Progress will carry 2.5 tons of food, fuel and supplies.


The resupply vehicle will launch from the Baikonur Cosmodrome in Kazakhstan on June 30. NASA TV will not broadcast the launch, but will show the live coverage of Progress’ docking at 11:55 a.m. on July 2. Live coverage will begin at 11:30 a.m.

In Their Own Words - NASA Astronaut James P. Dutton, Jr.

In Their Own Words - NASA Astronaut James P. Dutton, Jr.





NASA Astronaut James P. Dutton Jr.: Well, for me, I was one of those kids that wanted to do it from a pretty young age. I had that goal. I'm not sure exactly where it was, somewhere in grade school. And at that time, it was really one of probably many, you know, career aspirations. Along with playing in the NBA, or something like that, which didn't work out at 5-foot-9. But, about junior high school, I started to get a little more serious about the idea. Had a librarian from my middle school who on the career day helped me to look up NASA's address and write to NASA asking about how to become an astronaut.

And I got a brochure back from them telling me that, you know, you need to study math, science or engineering. And talked about the requirements for a pilot astronaut, which is what appealed to me the most. And, so, that's when I really started to set my sights on one of the service academies and just kind of took it step by step from there.

Well, the little bit that I got to fly the shuttle, which was just about 30 seconds flying around the heading alignment coming prior to rolling out on final, it flew almost exactly like the STA. Just felt like I was back in that airplane. You're partly so focused on the task, that by the time we were wheels down, I sort of went, 'I can't believe we just did all that for real.' But at the same time, I remember as we were coming around, looking down toward the, we had some clouds down below and toward the Vehicle Assembly Building, and trying to pick out the runway and just thinking, 'I can't believe this is like the real one,' because I had seen that picture so many times from the shuttle trainer.

As far as the actual launch, a couple things surprised me. One was the engine start. I thought it seemed a little bit more chaotic in the vehicle in terms of the vibration when the engines started than I remembered from our sim (simulator). So, that initial startup from to 100 percent on the engines is about six seconds prior to launch, and so I remember noticing that. The vehicle just shook in a different way than I had expected. And then when the solid rocket boosters lit, it felt like a bomb had gone off under your seat, you know. And basically, that's what happened, 6 million pounds of thrust, you know, instantly it's an immediate hit.

They're small jets that fire as the SRBs come off, but also, we have forward jets that fire to protect our windows from any debris coming off the solid rocket boosters. So, you see this big flash out the front windows once they come off and then it gets really smooth. It's pretty rumbly inside the vehicle while you're on the solids, and then once you get off them, you're sort of on railroad tracks. It's quite a ride, the 3 g's, you weigh three times what you normally weigh. Then, of course, you've got the suit on with different valves and things, so stuff's poking into you. It's really not bad, but you're aware that you're heavy. And then you go instantly from weighing three times your normal weight to weighing nothing. And floating up in your seat, and straps and all kind of stuff, you know, books floating up and dust comes up. So, it's really neat how quick that happens.

Well, I had high expectations and they were all exceeded. They really were. There's very little that I felt really surprised by. I think the veterans on our crew made a real effort to every time we were in the simulator talk about what's going to be like living up there, what it's like operating in zero-g, things that surprised them on their flights. So, we were, I think, really well prepared by those folks.

And then we were fortunate enough on our return, we came back over the U.S. for our landing. So, we hit sunrise on orbit somewhere around the West Coast, but we really couldn't see the ground because it was still dark on the ground. And, about the time we were over Wyoming, we picked up the sunrise on the ground looking right down on the Rockies. It was absolutely gorgeous and we were at 40-miles-high. We'd been at 200 miles for 16 days, so it looked really low and fast at 40-miles-high, which was kind of funny.

I mean, it's very fulfilling to have been blessed to go up and fulfill that dream. You know, to have experience what I had hoped to experience all these years, knowing that each step of the way, you're just very fortunate to make it to the next gate.

You know, there's health issues, there's professional career things that can come up that can divert you. So, I just sort of marveled. I mean, even to the last minute, I knew that anything can happen and it was nothing to take for granted. So I felt very, very thankful.

NASA Astronaut Rick Mastracchio: I had always hoped to get selected as an astronaut when I came down. I came down to Houston in 1987, and then I had been applying, ever since then, applying every year for the astronaut selection. And it took me nine years, till 1996, to finally get selected. So, I had always hoped to get selected. But, I had a great job as an engineer. So, if I didn't get selected, I was more than happy where I was.

I was always interested in space and science, and things like that. But I never really thought or even knew that you could become an astronaut. I had no clue until I saw an advertisement in a magazine when I was maybe 27 years old, 26 years old. We saw an advertisement in a magazine and I sent away for an astronaut application. And from that point on, I started to apply.

I had the opportunity to go out to Palmdale, I believe, when NASA was accepting Endeavour from the contractor. And I was actually one of the first people to sit in the Endeavour space shuttle as an engineer, and helped to verify and check out the Endeavour flight control systems before we accepted it for NASA.

Well, Endeavour was my mission, STS-118, about two-and-a-half years ago and that was my first spacewalk. And one of the things I got to do on Endeavour was, and we exit out of the space station airlock and all the spacewalks now. But I got the opportunity to translate into the Endeavour payload bay. So, I'll always remember translating down that payload bay and going into the back of Endeavour to work and remove some of the hardware from there that we were going to install on space station. It was on my first spacewalk and it was an exciting moment for me.

We had a problem. We had an 1,800-pound ammonia tank. We were trying to install this ammonia tank on the International Space Station. We bolted one of the bolts down partially, but it wouldn't drive the rest of the way. And we were having problems getting some of the other bolts to line up because the soft-dock feature would not grab. It was just resisting and it would not go down. So, we spent a good hour, hour-and-a-half, using various tools and techniques, even trying to kind of slam the tank home to get it onto its soft-dock so we could bolt it up and install it on the space station. And we tried for a long time and we just could not get it.

Eventually, I was kind of thinking in the back of my head, 'Well, I think what we're going to have to go is just release all these bolts and then try to kind of wiggle it around and get it installed.' And, of course, that's what Houston came back a little bit while, after that and they said, 'Hey guys, just remove all the bolts and let's try that.' So, as soon as we did that, we got it installed and all was well.

My first time out the airlock on a spacewalk, I opened up the thermal cover and opened up the hatch and we look outside and it was nighttime. So, which was kind of good because you're looking right down on the Earth and so I wasn't distracted by the Earth traveling below me. But it was, what was going on below was a lighting storm down below. And I could see the lightning dancing in the darkness, you know, the darkness of the Earth down below. So that was a pretty neat lightshow. So, I'll never forget going out the hatch that first time and just seeing that lightning all over the place. That was a great experience.

You know, every spacewalk is a little different. Some spacewalks, you go out there and you really feel like, 'Wow, I really did a great job on that one. I felt good about it.' Sometimes, you come in and say, 'Wow, that one really took a lot of energy. Took a lot more out of me.' But every spacewalk is a little different. There's nothing more satisfying, though, is when you go out there and you install a piece of a space station or you swap out a busted piece of hardware with a new one and Houston calls and says, 'Hey. We tried that new piece of hardware, it's up and running.' You know, that's always a great feeling.

I think people are going to look back on the space shuttle and think it was one of the most incredible vehicles ever built by mankind. Right now, I've been saying it and I'll continue to say it, that it's the most versatile, the most capable vehicle, spaceship, ever built by mankind. And it's going to remain that for many, many, many years.

There's nothing even on the drawing books to go off and build something like the space shuttle. And I think once it's gone it's going to be one of those things where people say, 'Well, now that it's gone, we sure wish we had it back.' But, everything must come to an end, and the Space Shuttle Program had done a great job. It's been very successful, and it's time for it to end and move on to other options.

Engine Removal to Finish Today

Thu, 24 Jun 2010 07:40:00 -0500

At NASA Kennedy Space Center's Orbiter Processing Facility-3, technicians have removed one of space shuttle Discovery's three main engines. The remaining two engines will be removed today and all engines will be taken to the engine shop in order to replace a turbopump in engine 1. The turbopump developed an issue earlier this week during a torque check.

Workers are also testing the Power Reactant Distribution System, which serves the electricity-generating fuel cells on Discovery. The payload bay doors were closed yesterday for plug installation today.

At NASA's Johnson Space Center, Mission Specialists Tim Kopra and Alvin Drew are rehearsing spacewalk procedures today in the Neutral Buoyancy Lab.‪‪

Discovery is to launch on the STS-133 mission to the International Space Station. The official targeted launch date remains Sept. 16, but a change request has been submitted to move the flight to Oct. 29, with STS-134 moving to February 2011. The request is under consideration and an announcement is expected at the first of July.

Summer Learning Champion - Charlie Bolden

NASA Administrator Bolden Named Champion Of Summer Learning WASHINGTON -- The National Summer Learning Association has recognized NASA Administrator Charles Bolden as a Champion of Summer Learning. The award honors Bolden's dedication to keeping America's middle school students engaged in science, technology, engineering and mathematics (STEM) through a new initiative called the Summer of Innovation.

Five leaders from across the nation who have invested in summer learning programs and helped increase public support for them will receive the award.

"Bolden's leadership on the NASA Summer of Innovation program has resulted in a major step forward on two critical policy challenges facing our nation: summer learning loss and STEM education," said Ron Fairchild, CEO of the association.

Bolden officially kicked off the Summer of Innovation June 10 at NASA's Jet Propulsion Laboratory in Pasadena, Calif. Using content from NASA's missions and research, the program will engage thousands of middle school students in STEM learning during the summer months when many students experience "summer slide," or a loss of skills acquired during the school year. Summer of Innovation is a cornerstone of the Educate to Innovate campaign President Obama announced last November.
 
"It is such an honor for me personally -- and for NASA -- to be recognized for our commitment to summer learning," Bolden said. "However I do want to single out two individuals without whom the Summer of Innovation would not be in place today -- Nicole Campbell, a White House Fellow who raised the idea of this program when she joined my staff, and Dovie Lacy, the project manager, who breathed life into the program. Education is a passion of mine, and I have asked that NASA's best and brightest get involved and make this Summer of Innovation a special and meaningful experience for these middle school students. They're our future and I want to ensure it is a bright one."

Turbopump Issue Prompts Engine Removal

Space shuttle Discovery will have its three main engines removed after a low-pressure oxidizer turbopump on engine 1 had an issue during a torque check. All three engines have to be removed to allow access to remove the center engine. The pump will be sent to Canoga Park, Calif., for repair. Engineers will consider several alternatives, including whether to wait for the engine and its new turbopump or to install another engine in Discovery that was slated for use on Endeavour. The engine work is not a hindrance to processing and is not expected to prompt a delay for the launch of the STS-133 mission.

The crew of Discovery is reviewing photo and television procedures today as they continue training for mission. The astronauts are also undergoing refresher training on International Space Station systems.
