Why can astronauts not use parachutes to help slow down their spacecraft?
The fabric of the parachute would catch on fire as they made contact with the atmosphere
How do astronauts slow their spacecraft down when approaching the moon?
Astronauts use small bursts from little jets pointed in the direction of travel to slow down the ship when they approach the moon.
How do astronauts return to earth?
Through a slow and controlled descent.During the space programs Mercury, Gemini, and Apollo, astronauts returned to Earth through a sort of crash landing. They fell through the atmosphere using a heat shield to deflect the massive amounts of heat built up do to the friction of the Earth against the spacecraft. When they were nearing the Earth's surface they deployed a parachute to slow them down. They then fell into the ocean, the spacecraft floated, and they were retrieved by a Navy rescue team. Then the spacecrafts could not be reused, they were a once only deal. Now the Shuttle lands much like an airplane does. It reenters the atmosphere and uses a heatshield of its own to deflect the heat. It has wings on the side which allow it control over its decent and it lands on a runway, also using parachutes to slow it down after it has touched down. The benefit of this style of landing is that the spacecraft is reuseable and can fly several missions.
Why might a spacecraft get too cold?
Because the average temperature in space is just 2.73 degrees above absolute zero in the Kelvin scale. After their oxygen tank exploded, the Apollo 13 astronauts were forced to shut down their spacecraft to conserve battery power necessary for re-entry. Following the shutdown, the temperature in the spacecraft dipped to near freezing temperatures. The only reason it didn't freeze was because they were heated by the sun for most of their journey. When astronauts went to the moon, they put their spacecraft in what was known as a barbeque roll to even out the temperatures both inside the spacecraft and back in the Service Module where their oxygen and fuel tanks were. Had they not done that, half of their spacecraft would have been frozen while the other half overheated.
Do they have Toilets in space ships?
Yes, but the astronauts have to strap themselves down first!

How astronauts slow their spacecraft down?
Using Reaction Control Thrusters or Cold Gas Jets (small thrusters). The astronauts fire them in the opposite direction that the spacecraft is traveling and this thrust slows down the craft.

How do the astronauts land on the earth's surface once their rocket has passed through the atmosphere?
They use parachutes on their module to slow down and then land safely in the water to be fished out later.

What is plant down?
Things like kapok and thistle down? Parachutes for seeds
What do astronauts fly in?
Astronauts in their spacecraft (such as the Space Shuttle) are lifted into space by huge rockets which accelerate the craft to "escape velocity" (about 25,000 mph). This puts the craft into orbit around the Earth, its forward velocity balancing the continuous pull of gravity. When they are ready to return to Earth, they use rockets to slow down, and gravity pulls them back out of orbit. When astronauts travelled to the Moon, another smaller rocket pushed the Apollo spacecraft out of orbit, and carried it to the gravitational field of the Moon. Another rocket firing pushed the craft back to Earth. Unmanned space probes have travelled to even farther distances from Earth, including the outer planets Uranus and Neptune. Most of the travel is coasting, because there is practically no matter in space to slow a spacecraft down.
What are the parachutes for on a rocket?
The parachute of a rocket is used to slow down the rocket when it falls down.
Can you fly while you are in a space shuttle in space?
You may have seen photos or videos of astronauts who appear to be floating through the air while in space. They aren't flying, nor are they really floating, they are falling. Any orbiting spacecraft (such as the space shuttle or international space station) is actually falling around the Earth in a circular pattern. They have achieved enough speed (over 17,000 mph) to continue moving around the Earth without the Earth's gravity pulling the spacecraft down. Astronauts aboard those spacecraft are moving inside the spacecraft and falling along with them at the same speed giving the appearance that they flying or floating inside.
How do parachutes work for a water rocket?
the parachutes slow down the rocket so it doesnt smash into peices when it hits the ground
What do parachutes do that cause skydiver to slow down?
simple air resistance
