How do rockets land ?

Question

i dont get it cause there are flying down with so much speed plaz tell me thanks

Answer 1

It depends on the rocket, although I am sure you are probably referring to the "space shuttle" / orbiter.

When the orbiter returns from space it is traveling incredibly fact (it needs to so that it can stay in orbit). Upon entering the Earth's atmosphere, friction between the orbiter and the air slow the craft considerably, turning much of this energy into heat (thus the need for a heat shield). But even when the orbiter slows down enough so as not to ionize the air and it gets down to a more modest gliding altitude, it is still traveling quite fast (it can travel clear across the United States in a matter of just a few minutes).
In order to get rid of this extra speed, the orbiter's pilot executes a series of "S" turns which cause the space craft to veer back and forth (in the shape of an "S") inn order to allow the air more time to slow it down due to friction. By the time the orbiter gets to the landing runway, it is now traveling much slower, but as an added braking mechanism, the craft is equipped with a parachute (like those on drag racers) which is deployed to slow the orbiter down even more after it touches down.

Other types of rockets / space capsules land in the water (splash down) or on land with the aide of parachutes, or even retro rockets to push the capsule upward at the last second to slow it down before it crashed into the ground.

Answer 2

Most rockets are simply sacrificed. They burn up in the atmosphere, fall into the sea, or are destroyed on impact.

On the other hand, there are several ways of arranging for a rocket propelled space craft to make a soft landing. A spacecraft or a section of one can be equipped with an ablative surface and parachutes, as the Mercury, Gemini, and Apollo, as well as the Soyuz spacecraft are.

It is also possible to fit a spacecraft with wings so that it can maneuver as a high-altitude glider and land on a runway, as the space shuttle does.

Rocket powered spacecraft have been designed so that they can descend and land tail first, in the manner that most science fiction writers imagined in the 1940s and 50s. This is tricky to implement, and is only in the early experimental stages.

Answer 3

The lunar modules of the Apollo missions landed on the moon using rocket braking. Basically they just went down feet first and fired a rocket to slow themselves down. Just before landing the pilots cut the rocket engine off.

Answer 4

Rockets are just tools to get cargo into orbit. They typically end up orbiting uselessly along with their cargo, or they burn up in the atmosphere, or they fall back to earth and splash down in the ocean.

If you're referring to crew vehicles, like the space shuttle or Soyuz capsules, that's a different answer. The space shuttle is very interesting, since it lands like an airplane. Obviously, it has to slow down somehow on its way down. To do this, it uses friction with the atmosphere to slow it down (this also generates a ton of heat, which spelled death for the astronauts of Columbia, R.I.P.). In fact, the space shuttle dosen't just line up with the runway and land. First, it makes wide turns shaped like the letter "S"...this allows it to spend more time plowing through the atmosphere, losing speed, until it is moving slowly enough to glide to a rolling touchdown at Kennedy.

Soyuz capsules (and probably the US's next crew vehicle) are more simple. They plow throught the atmosphere without guidance and finally parachute to earth.

Answer 5

Rockets don't land that's why they are used as weapons for Nukes and the like

If your talking about those old fashion space travel rockets like the Apollo series, then they also didn't land. The very tip of the rocket (cone shaped part) detaches on reentry and a series of parachutes slows its fall. The rest of the rocket is left to fall into the ocean

Answer 6

In the front they have something that opens and shoot out a mass of air and it works like a wall and slows the rocket down and that's whenu hear the boom.

Answer 7

they out one foot down and then another...slwoly...lol, jk!
So here's how they do it. You know how planes land that's how rockets land...except there is a cool "rocket-port" on the planets or whatever.

From inside the rocket they throw a space thingie...with four legs with astronauts inside it. The other rocket keeps going while hte space thngie stays. That is how it works...

Answer 8

Ummm previously with older space ships they crashed them out in the middle of oceans where they safely exited with no problem. There was a case out in the Indian Ocean where a team of astronauts landed and exited too quickly. They were saved but their ship sunk.

Answer 9

Some of them crash but if some information is needed from them they parachute them down.

Answer 10

they have parachutes that slow them down before they land like a plane does.
