No, not in space. Sound needs air to travel through, and there's no air in space. However, while they're inside their spacecraft, the capsule is kept full of pressurized breathable air, just so they don't have to wear their space-suits all the time. Since they do have air inside, they can converse without radio while they're in there.

How astronauts communicate in space?
they have radios, silly
Why did astronauts use radios to talk on the moon?
There are many reasons, but significant ones are related to available atmosphere. The astronauts must stay in their space suits to get breathable air. Denser air is better for the transmition of sound. So it is hard to get sound to go through the space suit and then hard to get it to go through the low density atmosphere of the moon. Radios are easier and can go much farther.
Why did astronauts need to wear space suits when they visited the moon?
There is no atomosphere or atmospheric pressure. Without atomspheric pressure the astronauts blood would boil.
Why do astronauts need radios to talk in space?
Sound is carried by vibrations of molecules. When you talk here on Earth, air molecules transmit the vibrations and allow others to hear you. In open space there are very few molecules at all so there is nothing to carry the vibrations. Radios use radio waves to transmit information from one to another. These waves move through space by themselves so they can be transmitted from one astronaut to another. Then the radio turns the wave back into sound in the air filled compartment the astronauts breath in.
Where astronauts ride?
Astronauts ride in a STS (Space Transporation System/Space Shuttle)

How do astronauts communicate outside the space shuttle?
They use radios built in their space suits.
Can astronauts speak in space?
Yes, astronauts talk in space, as they always have acess to oxygen.(using radios)
What happens to the muscle of astronauts who are in space of an extended period?
Astronauts' muscles atrophy in space due to the decreased work they do without Earth's gravity.

How do astronauts work on the Space Station without drifting into space?
The astronauts wear tethers whenever they exit the space station so that they remain attached to the station. Otherwise, without sufficient gravity to keep them close by, they could easily drift away into space.
Why do astronauts who land on moon talk through wireless sets using radio waves?
Sound needs air to travel through, and as there's no air on the moon. Astronauts have to use radios to talk to each other when in an envrionment without air. Radio waves travel through space and have no trouble traveling where there's no air.
What types of astronauts are there on a space mission?
trained space astronauts
Astronauts are--who fly in space?
Astronauts are people who fly in space
Is digestion not possible without gravity?
Digestion is not dependent on gravity. Astronauts do fine in space.
What is the purpose of the new space robot at the International Space Station?
it will help the astronauts make repairs on the ISS without having to do a space walk
How fast can a space shuttle travel to mars without killing the astronauts?
Theoretical, infinate, if you travel through warp space.
