Transcript:Captain Janet:Welcome to the JP AstroCast, where we are traveling at the speed of thought. Today's episode is brought to you by Hunt Brothers Pizza. Ah, Eyezak, what are you doing?Eyezak:Hey, Captain Janet. I'm just hanging up some pictures on these walls. New crew, new beginnings, new surroundings.Captain Janet:But Eyezak, you're using nails?Isaac:How else would I hang a picture?Captain Janet:Well, I don't know, but you don't put nails in a spaceship. That might puncture our hull, and then we would lose oxygen, and we need that to breathe.Eyezak:Oh, didn't think of that. Hmm.Captain Janet:Did you just hang that picture up with your chewing gum?Isaac:Yep. Problem fixed. Right.Captain Janet:You know, this post-it was supposed to be something entirely different, so okay.Eyezak:That ought to do it. Do you think our new crew will like my decorations?Captain Janet:I'm sure they'll love it, Eyezak.EyezakOkay. Do you think they'll like me?Captain Janet:Of course, they will. Everybody loves you.Eyezak:Usually, but these kids are super genius smart. They read lots of books and do experiments and want to do awesome things in space. What if they don't think I'm smart enough to hang out with them?Captain Janet:Eyezak,I am sure they will love you. And here they come now.Kid 1:Hello.Kid 2:Hey everybody.Captain Jane:Glad you guys are here.Captain Janet:All right, crew. Welcome to Janet's planet and happy to have you aboard. First, unpack your gear in your cabins and then meet Eyezak and me in the galley for some lunch. And then we'll beam up Dr. John Grunsfeld to speak about his work on the Hubble telescope and the newest thing in space, the James Webb Space Telescope.Maggie:That's amazing.Captain Janet:See Eyezak, was that so bad? They're really cool and super accepting kids. I know new beginnings are tough, but you're going to be just fine. And one of the esteemed JP space crew.Isaac:Oh, I sure hope so. I hope I don't ask Dr. Grunsfeld any not-smart questions.Captain Janet:Oh, Isaac. Here's the thing. There are never any not-smart questions. Now let's just go get ready for lunch.

He is fittingly an astronaut and astronomer. Dr. John Grunsfeld hails from Highland Park, Illinois, received a Bachelor of Science Degree in physics from MIT, a Master of Science Degree, and a Doctor of Philosophy Degree in physics from the University of Chicago. Dr. Grunsfeld has four NASA space flight medals, three NASA exceptional service medals, a NASA distinguished service medal, and many other special honors.Captain Janet:Dr. Grunsfeld was selected by NASA in March 1992 and reported to the Johnson Space Center in August 1992. A veteran of four space flights, Dr. Grunsfeld has logged over 45 days in space, including five spacewalks, totaling 37 hours and 32 minutes. During STS 1 0 3, Dr. Grunsfeld and his crew installed new gyroscopes and scientific instruments and upgraded systems on the Hubble space telescope, which required three spacewalks. STS 1 0 9 successfully upgraded the Hubble space telescope, installing a new digital camera, a cooling system for the infrared camera, new solar arrays, and a new power system.Captain Janet:Those upgrades required a total of five spacewalks in five consecutive days. He's watched Hubble drift against the background of earth and stars. And he's guided new parts and instruments into the telescope and left it whole and healthy. He has helped the science missions of Hubble and envisioned science goals for the James Webb space telescope. And is now an Emeritus scientist at Godard Space Flight Center, working on Hubble observations of Jupiter's moon, Europa, and collaborating on the design of the next generation of space. serviceable telescopes. Dr. John Grunsfeld, what an honor to have you beam up today?Dr. John Grunsfeld:Well, it's absolutely a pleasure to be on. I'm excited because we are on the cusp of an astronomical revolution. And for me, my telescope is the Hubble space telescope. And what's interesting is about a third to a half of everybody who lives on planet earth has always lived in a world with the Hubble space telescope. And that's because it's been in orbit for 31 years coming up on 32. Your telescope though will be the James Webb space telescope. And you'll be learning about the new universe that the James Webb Space Telescope sees over the coming years. So thanks for having me on board.Evy:How or when did you know you wanted to ...
