How to put a human on Mars
The mission will start with our launch and end at we’ll have everything we need to go to Mars.
We’re going to launch in a relatively conventional rocket, but at the top of that rocket is going to be a cruise stage and the re-entry vehicle to get us landed onto Mars.
There’ll be a short, ever-such short burn to get us away from the Earth and into this curve trajectory going towards Mars. During that our spaceship literally just split apart connected by our little tether, and it will start spinning to create this artificial gravity. Fingers crossed, there won’t be any solar storms on the way from the Earth to Mars and we can keep going nice and gently.
Once we get to Mars, we’ll re-tether it together, the astronauts will join in the nose-cone and it will be ejected into the Martian atmosphere.
This is why you need this big cone in the front to soak up all that heat going through the atmosphere. At 700 miles an hour or so, they will be able to release a parachute.
Right at the last moment on entry, the legs are gonna be deployed and we hope that the re-entry vehicle point gracefully descends on those retro rockets down to the surface of Mars.
Some people think that the use of humans is just something that is popular and very attractive from an adventure and inspirational point of view.But there are also real scientific benefits for sending humans.
Humans can get a process while they’re walking around, while they’re looking at the rock. They’re probably the most sophisticated computer, the most sophisticated robotic, living organism we can imagine.
There’ll be the building of the habitat and there’ll be some experiments on the Martian surface. After a couple of months we drive from our landing zone to the return launcher. We’ll get in that; hopefully we’ll be fueled up, fire off in the Martian surface and fly back to the Earth again.Source: https://www.bbc.co.uk/news/science-environment-23349496
