Welcome to the very first episode of nasa science live. this is is a change to take you behind the scenes to get to know the space agency.
Welcome to the very first episode of nasa science live. this is is a change to take you
behind the scenes to get to know the space agency.
today we are talking about moon. but before we get into that.here are the most recent nasa news.
we are all broken hearted saying good to the rover.it lasted 15 years. despite the original mission proposing it for it to last 90 days.
you know, it is not all sad because it afforded awe new generation of space exploration.
when this mission ended, we announced a new mission and look at the origins of the universe and it is salmonellaed spherex.

why did the june verse expand
so rapidly after the big bang?
I know nasa expanding the that we do science, instead of designing and building, we buying the space. this is hopefully fast tracks the science, so much so that we have new science on the moon in as early as the end of this year.
so, speaking of the moon, let's talk about our cosmic next door neighbor. it has been 50 years since first going to the moon, the
moon is the greatest achievements.
what dusz it take to go back and generated a lot of questions and we have to go back to find out more.
over the course of our show today, we are talking about a few important things, the earth, the moon, the lunar legacy and moon mysteries and ask nasa portion, that is a chance for you to ask us questions.
and for our experts to answer them.
so our new goal is going back to the moon for long term exploration, and this has a host of challenges that didn't exist 50 years ago.

why going back to the moon. because it is the key to history of our earth, our solar system, deep space missions to mars and with all of the new charges, we have to understand its environment.
just to give you a frame of reference, the longest an astronaut out there is just three days, going back long term we have to understand the environment a. huge and critical think to think about is the radiation.
here on earth we have the atmosphere, that is going to protect us. anything on the moon is baldly exposed. so we are going to hear more about that.
the sun is a damaging source of the rated yags, all objects have to contend with the
hazard, including the planets.
new research suggests that the color ration on the moon could be a form of sun burn.
the leading high thot sis that is the field is blocking the solar wind from reaching the surface. the radiation fills the inner solar system and protecting against it.
the magnetic field on the moon.it is funneled by the regions. the shielded areas under the field form parts and they become darker and the contrast is prominent.
the magnetic fields in some region is acting as a sun screen, stiechls you miss a bit and you have a bright red spot on the skin, that is the analogy of this sort of region of the moon that is extra exposed.
the moon's passages are not robust enough to protect from the sun's radiation, further 24 years study of the magnetic fields leads the ground work.
What if we can produce artificially shs that is a question that remains to be answered and the magnetic fields on the moon and the swirls provide a hint in that direction that we might be able to learn something about.
So with us today we have three experts that aring go to give us a better idea of what it takes to go back to moon.
we have dana hurley, a planetary scientist and noah petro and kegly young, reearch
space scientist.
we have astronauts that would be there for a long period of time or astronauts coming and going, and being able to go out to do
experiments across the surface and that sort of thing so we need to protect them from the radiation that the sun is spitting out and that is coming through the solar system from the galaxy. and so, one of the ways to do that is by building the shelters for them.
if there are high energy particles they can get out of the way. but, yeah, so that's the big environment that we have to deal with for the astronauts.

I heard something about a bit of water on the moon? yeah, that is really enabling if we want to have sustainable presence on the moon is that there is water and in the shadowed regions near the lunar poles and if we can use the water on the moon, we don't have to take it with us and that's big cost savings in that enables us to send more missions to the moon if we don't have to take everything with us and using the products that are already there.
How much water are you talking about there, is it a lot?
it is a lot for the moon. ten years ago we didn't think there was water on the moon.
over the last ten years we have discovered there is water here and we probably could fill up maybe one thousandth of lake erie if you put all the water together. so there is water.
The next question is for you, you had the opportunity to are study a little closer than we are here on earth, so what do you know right now about the lunar environment today and what have we learned?
