I think like Hubble reached out and wanted that. John Grunsfeld: What I find really fascinating sociologically is, when I trained on the robotic arm, we actually have a large hydraulic arm in Houston that I could drive around and practice with. So Mat, over to you. Grunsfeld studied binary pulsars and energetic x-ray and gamma ray sources using the NASA Compton Gamma Ray Observatory, x-ray astronomy satellites, radio telescopes, and optical telescopes including the NASA Hubble Space Telescope. Again, I credit the amazing engineers who designed it. Ad astra. Mat Kaplan: Well, dog singular in our case, but that'll do, he'll do. John Grunsfeld. [6] He attended the Massachusetts Institute of Technology, earning a Bachelor of Science in physics in 1980. It was imagined, well nobody could get out there. So over time, Hubble will slowly spiral in to our earth's atmosphere. I think with that, we're done. By build, I really mean build. Michael Massimino served with both Altman and Grunsfeld on STS-109, and performed two spacewalks to service the telescope. Mat Kaplan: Time for What's Up on Planetary Radio. I mean, it's really incredible that just in the last 100 years, from Edwin Hubble observing on a 100 inch telescope to the Hubble Space Telescope, which has only about 94 inches across, that we've been able to put together a story of the origin of the universe, the big bang, to the expansion of the university, to the formation of galaxies, of black holes, of planetary systems all the way through the formation and evolution of the earth in just 100 years is pretty incredible using observatories like the Hubble Space Telescope. Think of how many other earths are out there. So, James Webb will really be like having another Hubble in a new realm. In this call he complained about his government Rockwell "van's" performance. Atlantis launched from Kennedy Space Center Launch Pad 39A May 11, 2009 at 2:01 p.m. EDT, and landed on May 24, 2009 at California's Edwards Air Force Base. In five days of docked operations more than three tons of food, water, experiment equipment and samples were moved back and forth between the two spacecraft. Did anyone make the suggestion to tighten it slightly then try again to loosen it? But still, the ride to orbit is incredibly dynamic. That decision on James Webb was made very early on. Here's a question that came in actually before we started the hour from Mike Helton. We've got the sky overhead in the backyard, so we've got a lot to look up to. When we put the protective cover back on, which was not intended to be left on the telescope, their thermal problems went away, because the outside of that cover is white, and now they don't have to manage that anymore. Q: Why was the team surprised at the torque needed to remove the screws? There aren't ultraviolet telescopes on mountaintops, because the ultra light doesn't make it through our atmosphere. Mat Kaplan: Before we get to that, I mean, apparently Northrop of Grumman likes to name these after lots of interesting space heroes. I'm glad you're back. I think this image and many other Hubble images, highlights the value of the Hubble Space Telescope, which is amazing science. I'm wearing gloves today as a matter of fact. Mountain climbing comes closest, but not the real importance to society or the world. Do you meditate before launching? I had to go back out and put that antenna cover on. Each spacecraft gets light from a different path direct from the sources. Drew and I, were highly trained. Why do we still get Hubble space images years past the orbiting telescope's life expectancy? John Grunsfeld: But, the other part of it is, it's a cryogenic telescope and very delicate. Thank you. It's like lifting a 30 pound barbell if you get a big box like that moving too fast, you've got to be strong enough to stop it or it'll slip right out of your hands. Bruce Betts: Here's your question. But, it was tense for a little while. John Grunsfeld: I think a combination of those modes is what you want. Using that word though, we forget about Hubble's, its infancy when it first got to orbit. We have captured in each of those images, the moon of Mars Phobos as it moves along in its orbit. Q: Here's a personal question for the astronauts onboard the Hubble repair mission: What was it like when you looked out a shuttle window for the first time and saw Earth? I was just so happy.". John Grunsfeld, an astronomer, has serviced Hubble twice, performing a total of five spacewalks on STS-103 in 1999 and STS-109. It weighs about 800 pounds. In fact, Congress agrees with that. We really sweated that for a long time. John Grunsfeld: As I said, 11 years ago, I was on orbit with this crew. For instance, the case systems for the International Space Station, they tried to build a model like that. John Grunsfeld closes our coverage of the Space Foundationâs 32nd annual Space Symposium in Colorado Springs. On April 5, 2016, Grunsfield announced his retirement from NASA, which starts from April 30. The mission docked with the Russian space station Mir, exchanged U.S. astronauts living aboard the outpost, and performed scientific research using the Biorack payload. HOUSTON John Grunsfeld was sitting in an astronomical meeting in Atlanta in January of 2004 when he got a message to come back to headquarters in Washington to talk about the Hubble Space Telescope. Robert Picardo ⢠Ever since then, we think of Hubble as the greatest thing ever.
