Space Exploration


And we have a very exciting guest with us today. Jim Green is the chief scientist at NASA. He also has his own podcast by the way called gravity assist. And he's going to see if he can answer all of your questions or at least most of them. Jim Thank you so much for joining us today. Jane thank you so very much for inviting me. The got a very well connected with Vermont. You may not know this but I was born and raised in Burlington. I did not know that. That's great but non burlington Vermont Brewington. I there're BURLINGTON's there are and I think Burlington Iowa is actually named after Burlington Vermont. So I'm well connected. Well that's good to know I'm Jim we're going to dive in because I think probably four thousand. Six thousand twenty thousand questions are coming in from kids all over the country but right before we get to the questions from kids. Could you just tell us a little bit about this? Launch on May twenty seventh. It's pretty exciting. It's very exciting. This is the first launch that we've had since with humans going up to the International Space Station since our our shuttle program ended several years ago. Now how we been going space station is not from rockets. Leaving the United States but With our of the Russians and so it's great to get back into the space business with our own rockets Of course we're we're building some really big ones. That will take us in a couple of years to the moon and there's onto Mars. We don't have to go into this too much. But when you say it's IT'S A. Us rocket but SPACEX is a private company right so this is sort of a government and a private company working together to get Americans into space so talk two thousand and six NASA decided. Hey we're gonna be able to bring what we know about space into our companies in and using that new environment where you take gravity out of what we call the equation and new things can be made we better start commercializing that means we need to be able to get more companies involved in space in the first place of course is low earth orbit and the a wonderful place to go of course is our National Laboratory International Space Station so In two thousand six we started that process of getting more more commercial companies interested in way. Indeed we now have several commercial Lockett companies that are building the capability. Take humans along with a number of commercial experiments up to space station. And while they're doing that we're going to move on to the moon and then on to Mars so it's a wonderful partnership so the the astronauts that are going next week are going to the International Space Station. Which as you said is in low earth orbit so this is not as far as the moon. It's not Mars. It's not. They're not going way out but but they're going into space and Donnelly who's eleven and lives in Saint. John's Barre Vermont has a question because Donnelly saw the International Space Station last night and a lot of people have been able to see the ISS in the sky. It's a bright light brighter than most stars and only says last night I saw the international space station fly by overhead in only half an hour it had gone from the area of the Earth where it is to the area where it is day to the area of Earth where it is. What is that like for the people on board? Well they still have a regiment. They still work hard to to Use the life cycle of light in dark that we have here on Earth on space station so indeed. They work on space station Over a twelve hour period have a few hours of a on their own to rest and relax and then eight hour sleep period and then back to the grind so to speak so on station they try to keep it as normal as possible. So you know when night comes. They turn off all the lights on space station even though we orbit the earth and we go from day to night In Ninety minutes of full orbit of occurs and that that's the that turns out to be the best approach

Coming up next
