How do astronauts return to the earth. How do they propel their space shuttle back into the earth's atmosphere?

The thing that keeps objects in orbit around the Earth is their speed. It is a balancing act between the speed of the object trying to throw it out into space and gravity trying to pull it back toward Earth. If the object slows down gravity wins and it will fall back to Earth. So, to reenter they simply slow down.

How fast does a space shuttle move in space?
Space shuttles use the gravitational pull from planets to propel/ sling the shuttle with speeds of up to 14 miles per second. Due to the lack of friction, moving objects take longer to slow down and accelerate quicker.
What do you do if you get lost in space?
To avoid getting lost ion space an astronaut should always hold their mommy's hand. If they do get lost they should retrace their steps carefully to where they were when they last saw their spaceship.-- Answer --Astronauts, when they go out into space, tether themselves to their ship and carry small, hand-held devices that can shoot out concentrated streams of air. That way, even if the tither does break, they can propel themselves to the ship. As to what happens if they get lost, if they cannot communicate with their ship, nor see it, they're generally dead unless they regain communications. (Oh, and personally, if I was lost in space, I would scream. But that's just me. Or propel myself into Earth's atmosphere.)
How do rockets propel a spaceship forward?
Thrust
What observations led czarnowoski to form his hypothesis?
How easily penguins propel themselves
Action-reaction engine that propel an object forward?
One good example: Balloon with a hole in it.
What is a engine used on a spaceship?
There are actually two types of boosters that were both used by the space shuttle before their decommission. To propel the vehicle out into space from the surface of the earth out past the atmosphere, the shuttle used SRB's, or Solid Rocket Boosters. The engines on the actual shuttle are LRB's, or Liquid Rocket Boosters. These are used to propel the space vehicle further into space and into orbit around the earth.
How many external boosters propel the space shuttle into orbit?
two
Would it be easier for a plane to fly higher in an atmosphere less dense than Earths?
i No, ;it would be easier in denser air. Less dense air gives nothing for the wings of the plane to use to propel itself upwards. Less dense air would make the plane crash.

Would a human float with ease on Pluto?
A human could float with ease on Pluto, but could not propel himself/herself due to lack of significant atmosphere.
What is the same of propel?
the same as propel is tug.
Why does a spaceship need two or more engines to launch into space?
One is simply not enough, the first stage of a space shuttle launching only generates 25 Mega newtons which I not enough to propel the spacecraft out of orbit.
Can sharp rocks propel a boat?
no,you can not propel a boat because propel means to push or drive forwards
What is a sentence for the word propel?
The boat PROPEL by the rowers rowing
When was PROPEL Berhad created?

Its got wings to propel it?
It's got wings to propel it
The pH level in propel?
