america is the greatest place on earth — the greatest place on earth, thank you. and he may have seen off one of the greatest threats to his presidency. there is much more to discuss about that story, we will revisit it later in the programme. a pro—military political party in thailand has performed better than predicted in the country's first election since the army took power five years ago. the palang pracharat party won about half a million more votes than the main opposition party. official results, which were postponed from sunday, are due out in the coming hours.

birth is not fragile -- earth is not fragile. earth has survived millions of years. we are fragile. the thing the apollo eight ussion gave us was allowed to see we lived on a water plaen controlsater really everything on this planet. it helps us to understand we control our own future and destiny. we can squander it and leave ea rth with the cockroaches that survive nuclear war and everything else, but no humans. they will go the way of the dinosaur. john: thank you very much for your question. >> i am a recent graduate of osu. john: my son would be proud. his first name is anthony. he does not use it much because he did not want to be called tony. >> a couple ideas bouncing around. one is collecting space junk from orbit. that would be nice to recycle different material and to clear off all of that space. with the policy that whoever launched it owns it, if the system was created by a private company and launched from the u.s. and came back, say there was a piece of unidentifiable space junk and multiple countries thought it belonged to them. how do you think that would play out? j

we've got the data for earth. we've got the data for the moon. which is formed a little bit differently. and it's small enough that it didn't have the same exact processes. we really want to see this data from mars to see the intermediate mix of a planet that never had plate tectonics, so actually, we think its current structure locks in what it looked like when it finished forming four billion years ago. we want to understand, does it have a solid core, or not. how big is that core? we have about, a big various in it, we want to get it down about a factor of four better than we know right now, how big is that core exactly. and how thick is the krufrt. how does that vary. all of those answers are what insight is trying to look at, is that interior structure that we can't see from the surface. >> you already know that it has a molten core? >> we think it does but it's still uncertain. so that's what insight is actually trying to look at. >> okay. and given some theories that the moon was actually crashed into the earth, and then separated into two

luckily the abort system worked and they landed safely on earth. but there was then a delay in the manned launches to the space station of about a month or so while they investigated. luckily it was an easy to fix problem, but if it was difficult and we couldn't launch astronauts, then we really would have been up the creek, so we really need the spacex dragon to come online as well as a competing system, boeing starliner will come on later this year, both of these are funded by nasa. that way we will have three ways to get the space so if one goes down we will have two other ways to get here. that is why it is so important. that is what i wa nted it is so important. that is what i wanted to ask you about, this other launch happening in april, with boeing. is this the future, moving towards a sort of more us style, nasa style space exploration programme? yes, this opens a com pletely programme? yes, this opens a completely new era in spaceflight. in the past, the capsules were designed by nasa, they were built by industry but basically designed by
