earth to. perseverance roseboro from nassau touches down after a 7 month journey for a quest to find out whether life once existed on mars also coming up a search for answers continues a year after a racist attack in the german town of qana has left 9 people dead was enough done to prevent it and could it happen again. hello i'm terry martin good to have you with us now is celebrating the successful landing of its most advanced spacecraft yet on mars there is space rover perseverance touched down safely inside one of the planet's craters after a nailbiting to sent the robotic vehicle will make history by collecting samples of martian soil to be brought back to earth that could help scientists determine if life ever existed on the red planet. at that kind of habitat it. became of. the moment scientists happy could be a way to. get i discovered that one of the 1st and this is what it looks like the 1st images beamed back from moss small high quality images will be sent back in the coming hours an

like, the earth is fragile. i saw that, when i had the world in my window, somehow that fragility got its way to the forefront, and i remembered it more than some of the other beautiful aspects of it, and as you think about our planet here, the planet earth, fragility is paramount in many, many ways. it's a very important idea that we are on a fragile surface, doing things to this fragile surface. now, that was the world in my window. but that's not an exclusive view, or point of view, you all can have the world in your window, if you want. i mean look at what you see, when you think of the world, when you think about putting your vision out through a pane of spacecraft glass perhaps, but the point is, you see this little thing, you see it in its entirety, you understand walking on it daily, is it fragile? oh, lordy, lordy, yes. can some of those, some of those manifestations of fragility be corrected? yes, they can. if we put our mind to it. so world in a window, that's an important concept to me, and i hope it

they were back on the path to earth. but there were many other problems to be solved.m a building at houston's manned spacecraft center, systems experts coordinated the coast-to-coast effort to get the crew back. one of the big problems was consumables. there would be enough to eat and drink. but in space there are other factors. oxygen to breathe, electrical power to keep the spacecraft alive, water to cool the equipment and keep it operating. >> what we'll be doing till we get back on the water is concentrating on everything that their lives are dependent upon at the moment rather than worrying about the accident because there's nothing we can do about that now. it appears at the present time that everything is under control and that we have a safe situation at the moment. >> you guys are doing real good work. >> so are you guys, jack. >> we are about 70 hours from home. and we think we have the situation in control. we've projected the consumables as i've described. and we have a plan for carrying out the rest of the mission. but there is going to be no relaxation a

well, they did exist on earth 3.5 billion years ago.mars at the bottom of lakes? for the first time, nasa will also be testing a mini mars helicopter to provide a new bird's—eye view of the planet. and back on the ground, the rover will store some of the rocks — a future mission will bring them back to earth, and some will be heading to the uk. these will be the most precious samples that we have on earth, the most exciting, and scientists around the world will be absolutely fighting and clamouring to study them. getting to the red planet is just the start. now the hard work begins. this is nasa's most ambitious mission and our best ever chance to know where life ever existed on mars. rebecca morelle, bbc news. dr briony horgan is a associate professor of planetary sciences at purdue university in the us, and one of the scientists working on the mission. she gave us her reaction to the landing. we are so excited to get those first images back! you know, the landing is one thing, but when we got to see those rocks through those images, i

it's earth from apollo 8. that to me is the most iconic photo for humanity, because it shows our planet as one with no borders, no boundaries, and it gives us the sense of responsibility for preserving that planet the way they saw it back then. >> yeah. it's bill landers who took the photo who says, we came all the way to the moon to discover the earth. >> i was the capcom for apollo 8 and then of course flew on 11. i can recall this was the first flight to exceed escape velocity. this was the first time humans were leaving their planet and going elsewhere. apollo 8 in my mind was of extraordinary importance. it was about leaving. apollo 11 was about arriving. okay. 100 years from now you put these historians like john. john would have a symposium, a nine-day symposium to figure out which of those two is more important. [ laughter ] >> leaving or arriving. you know, the older i get, the more i get tilted toward apollo 8 rather than apollo 11. i think the concept of outward bound, i think, it was alfred lord te
