How do spaceships land on other planets?
To land on a planet, one must slow down from orbital speed (tens of thousands of miles per hour), to a standstill on the surface. Re-entry friction with Earth’s thick atmosphere reduces a spacecraft’s speed enough for parachutes to provide a gentle descent.

What 2 planets have we landed on?
Explanation: Only our two nearest neighbours Venus and Mars have been landed on. Landing on another planet is technically challenging and many attempted landings have failed. Mars is the most explored of the planets.
How do spaceships land on the moon?
The Eagle has landed The Eagle lunar module had a descent rocket engine to slow it down, drop into a lower orbit and then hover over the surface. Guided by a landing radar, Armstrong piloted Eagle semi-manually using four clusters of rockets to finally touchdown in the Sea of Tranquillity on 20 July 1969.
How do spaceships land on Mars?
With a large lander, use retro rockets and landing legs to touch down, going about six miles an hour. Or, with a large, heavy rover, use a big jet pack to slow down to under two miles an hour. Then, gently lower it on cables to land on its wheels.
What are the steps for the rover to land on Mars?
