★ How to Get to Mars. Very Cool! HD


We don’t fire a rocket motor all the way to mars. We don’t need to You just place the spacecraft on a trajectory to mars and let it coast for seven months and 300 million miles until it reaches the planet Atmospheric entry in 3.. 2.. 1.. Just passed in one minute that atmospheric entry current altitude 121 miles, current velocity 12,084 miles per hour We are now at an altitude of 73 miles moving at a speed of 12,192 miles per hour expected parachute deploy in five seconds four three, two, one, Mark We’re awaiting confirmation parachute has deployed Parachute was detected Heat shield deployed event Spacecraft reporting the scene field at the – Planet separation event has been detected. Spacecraft reporting lander has separated moving at a speed of 173 miles per hour We are near our terminal velocity Expected retro Rocket ignition on my mark – Mark. At this point in time, we should be on the ground Any signal that we receive from now indicates the vehicle would be alive on the ground and bouncing The Spacecraft has to survive all the bounces for landing to be a success No signal at the moment Standby Signal strength is currently intermittent We don’t see a signal at the moment What do we see? We’ve got the signal! [cheering] The first thing we have to do after we land is open our solar panels to the sun So we’ll have some power.
