yes, it is extremely difficult to fly on mars. is about i% of the atmospheric pressure on earth. it is kind of like if you are flying at around 100,000 feet — excuse me, i use feet over here — and yeah, about three times the height of mount everest. it is critical, keeping the mass down, very critical. how are you fuelling the drone? it is actually powered by a solar panel that sits on top of the helicopter. you see the rectangle on the top, it charges the battery pack at the bottom. that not only powers our flights, it keeps us warm during the extremely cold at martian nights. it can get down to —130 celsius, quite cold. and just briefly, joshua, what is the way forward for this now and how could it be used further down the line? there's a lot of applications for any flight on any atmospheric body, so not only mars, but titan, the moon of saturn, has atmosphere, as well as venus. slightly different conditions there, but a lot of the reservoirs are the same. as far as mars go, science, exploration into hard—to—reach exploration in

ingenuity took off from the dusty red surface of mars this desire crater early on monday but the data took several hours to reach a milestone for space flight that nasa scientists compared to the 1st flight on earth by the wright brothers in 1903 technology demonstrations are really important for all of us you know it's really taking a tool that we haven't been able to use and put it in the box of tools that they said they'll go for all of our missions going forward at mars if we really want to explore the red planet possibility of power 5 present microbes and things like under different conditions. we're going to need to travel quite a distance which a helicopter like this with absolutely allows. flying a helicopter or drone is a seemingly simple task on earth but engineers aren't used to flying them on mars. the flights can be affected by many things the martian atmosphere is very thin and so it's more difficult for the helicopters one point to me to retrieve plates to lift itself up. in its test flight on earth scientists had to create conditions similar to miles the ingenuity weig

and we have started it by flying at mars. it's a huge deal for humanity.capturing its own shadow below and anotherjust before it touched down. until now, nasa had no guarantees this would work. these flights are testing cutting—edge technology. on board are solar panels and a thermostat, so the helicopter can survive temperatures down to —80 degrees. for each flight, scientists upload a plan, but ingenuity also has to make decisions by itself. high—tech cameras and sensors can spot obstacles, so it can adjust its height to avoid these. but the helicopter can also use these features as landmarks so it could navigate its way down to the ground. this flight is just the start. in the coming days, the helicopter will begin to fly further afield and it could transform our view of mars. helicopters can cover more ground, can act as scout vehicles, can go into different areas that the rover can't go into. and then they can do co—ordinated science data. future manned missions to mars can utilise a drone helicopter. so there is a lot of opportunity. more than 100 ye
