This Week at NASA…
COOL UNDER PRESSURE - JSC
Reporter: "I think what a lot of us are wondering about is making sure that everything is up and running again."
Tracy Caldwell: "Shannon and Doug removed the last jumpers today and put the racks back and so it’s all spic and span and it’s back to business as usual it seems."
The International Space Station’s cooling system was reactivated and finally back in normal operation.
Mission Control: "The pump is looking good."
Doug Wheelock: "Oh, Sweet! We got our station back!"
Three spacewalks by Expedition 24 Flight Engineers Doug Wheelock and Tracy Caldwell Dyson were needed to remove and replace a failed ammonia pump that had disabled one of the station’s two cooling loops on July 31.
Tracy Caldwell: "I'll pull it."
Doug Wheelock: "There you can see it."
Mission Control: "Yep I see."
The final EVA, a seven-hour, 20-minute outing, completed the complex task. Flight controllers at the Johnson Space Center then spent the next three days reconnecting various on-board units from their system-saving "workarounds" to the newly-restored cooling loop.
Courtenay McMillan: "The whole team is in a great mood and everybody is looking forward to some well-deserved rest after the efforts over the last couple of weeks."
NASA’S TECHNOLOGY SUMMIT - HQ
The agency held its first Information Technology Summit bringing together government and industry leaders from across the nation to discuss and showcase the best in private and public IT innovations. Over a thousand people participated in the event held outside Washington. Presentations ran the gamut from social networking and green IT to security and privacy.
Charles Bolden: "The president wants all of us and all of you to come up with better ways to move the government forward on IT. The IT role in NASA’s success with exploration using systems and applications that control space missions is obvious, but if we dig deeper, we see how extensive the IT support really is".
Administrator Charles Bolden led a list of speakers that included U.S. Chief Information Officer, Vivek Kundra, and IT executives from Disney and Google.
OPEN-DOOR TESTS CLOSED OUT - DFRC
Researchers at NASA's Dryden Flight Research Center have recently completed the second and final phase of flight-tests on the Stratospheric Observatory for Infrared Astronomy.
The performance and structural integrity of this airborne observatory, also known as SOFIA, was validated through a series flight tests that confirmed the aircraft could operate safely at various flight conditions with the telescope's door open.
SOFIA technicians at the Dryden Aircraft Operations Facility in Palmdale, California, will now finish installation and checkout of the remaining systems that support telescope operations.
The modified Boeing 747 is now approved to begin flying astronomy missions at altitudes as high as 45,000 feet later this year.
TOP TEACHERS SCHOOLED – MSFC
Outstanding educators from across the country learned a thing or two about space and its technologies during the Marshall Space Flight Center’s International Space Camp. Each state’s 2010 Teacher of the Year participated in a week-long series of events including training on space station and shuttle simulators, lectures and lab sessions about space history and rocket technology. They also learned innovative hands-on techniques for teaching students about America’s space program.
Sarah Wessling: "One of the great things about the experience is that we are learners too, and as teachers, first and foremost, we have to be learners; we are the lead learners in our classroom, and so this opportunity of learning, and collaborating ,and sharing, and experiencing so many of the wonders of space, can’t help but motivate us to take that back into our classrooms."
Teacher of the Year is the nation’s oldest and most prestigious honor bestowed upon educators.
EXPLORATION DAY AT BUSCH GARDENS – LARC
Students, their parents, teachers, grandparents and others spent two fun-filled days enjoying the wonders and mysteries of space during NASA Exploration Day, a joint venture between the Langley Research Center and Busch Gardens in Williamsburg, Virginia.
Roger Crouch: "You get to go to work every day and you get to work with puzzles and computers, doing experiments and all kinds of fun things, and so that’s a great career."
Activities included a talk from former astronaut Roger Crouch and the "Exploration Experience," an interactive trailer exhibit which uses 3-D imagery, audio effects and the latest video technology to re-create the challenges of space flight.
Guests also had the opportunity to check out Mars and points beyond, learn how future explorers might live and work beyond Earth’s orbit, and touch a real moon rock.
NASA Anniversary, August 21, 1985 – GEMINI V LAUNCH
Forty-five years ago, on August 21, 1965, astronauts Gordon Cooper and Pete Conrad launched from Cape Canaveral, Florida on the Gemini V mission.
Launch Control: “Lift off! We’re off on the hour.”
the third manned Gemini flight. The eight-day mission evaluated the guidance and navigation system needed to rendezvous in space, and the effects on astronauts of prolonged exposure to zero gravity. With this flight, the United States took the manned spaceflight endurance record from Russia, while demonstrating crew survivability over the length of time required for a lunar mission.
And that's This Week at NASA!
