There is no air on the moon. Its atmosphere is so thin as to be nearly undetectable. Without bringing oxygen from the Earth the astronauts would have perished.

How long would it take to send a crew of four astronauts to mars?
7 months
How did the lunar rover communicate?
The Lunar rover is not a robot as such like the Mars rovers. It was a sort of electric dune buggy controlled by the astronauts. It had both radio and television capacity. Oh, the camera mounted on it had a remote control that a man in Mission Control could operate. He was able to televise the liftoff of the astronauts by knowing just when it would take off, where it would go, and how long it would take for the camera to obey his orders.
What is the training astronauts go through?
Astronauts go through a great deal of training prior to going into space. It can take years for astronauts to go through all the training they need, which includes learning to work in zero gravity and going through a variety of realistic simulations.
Why do astronauts take plants into space?
to decorate the shuttle lol
Why don't astronauts take toads into outer space?
Ask a astronaut....
Why will astronauts need to take air to mars?
astronauts will need to take air to mars because the atmosphere on the planet cannot contain any oxygen, thus no oxygen to breathe.
Could astronauts terraform Mars?
Possibly. It would take generations to accomplish though.
How long would it take to send a crew of four astronauts to mars?

Why didn't NASA send astronauts to Mars instead of the unmanned 'Pathfinder' discovery mission?
Sending human beings to Mars is substantially more dangerous and expensive than sending an unmanned shuttle. It would take many days for astronauts to reach the red planet, and large quantities of supplies would need to be sent with them for them to survive the journey and to spend enough time on Mars to collect useful data and samples.
What would you need to take with us to mars?
A toilet.
Who would you take to Mars?
i would take an astranant to mars
How do astronauts get the supplies they need to live?
They take it along with them.
Has a space shuttle taken photos of mars?
Astronauts aboard the Space Shuttle may well take photos of Mars as personal souvenirsif they have time, but the photos would have very little scientific value.The Space Shuttle operates at about 0.0005 percent of the smallest possible distance between Earthand Mars. The Shuttle astronauts don't get appreciably closer to Mars than you do in your kitchen.If additional imaging of Mars is required, it might be acquired by the Hubble Space Telescope, or bythe two rovers currently operating on the surface of Mars.
How can you live on Mars?
it is possible to live on Mars but to do this you would need an atmosphere, and to have an atmosphere you need gases. To make these gases (there have been discussions about this) you would need to build factories to give off green house gases and make an atmosphere, because Mars is extremely cold at night, then we would have to get people to Mars. This would cost billions and would take a long time to build the atmosphere.
Why do you not just go to mars?
One of the main reasons is because the trip would cost billions of dollars. There is also a lot of radiation between Earth and Mars, that we are unsure of how our bodies would react to. But we know that the risk of developing cancer after visiting Mars would sky-rocket. There is also the "Mars is really far away" problem too. It would just take to long and we don't have the tecnology to ensure the safety of our astronauts.
How will astronauts get oxygen out of space?
They need to take it with them. There is no oxygen in space
What would you need to take to planet mars?
Peanut butter and jelly sandwiches so you do get hungry!
