Since there is no air, the sound waves would not travel. Radio waves being electromagnetic do not rely on matter (atmosphere) to conduct them.

Why did the astronauts have to use radios on the moon?

Astronauts on the moon used radios to communicate with mission control and other astronauts. The distance to Earth was too great for them to communicate in real time without radios. Additionally, the space suits and helmets they wore made it difficult to communicate verbally with each other.


Can astronauts have a conversation in space without radios?

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?

Astronauts communicate in space using a variety of methods such as radios, intercom systems, and video connections. They can communicate with each other, mission control on Earth, and other spacecraft using these systems to coordinate tasks, receive instructions, and stay connected while in space. Additionally, astronauts use specialized software and protocols to ensure effective communication despite the challenges of operating in a zero-gravity environment.


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.


List of Russian and Soviet astronauts?

Some notable Russian and Soviet astronauts include Yuri Gagarin, the first human to journey into outer space, Valentina Tereshkova, the first woman in space, and Alexei Leonov, the first person to conduct a spacewalk. Other significant astronauts include Vladimir Komarov, the first human to die in a space mission, and Gherman Titov, the youngest person to orbit the Earth.

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.

How do astronauts communicate in space?

Astronauts mainly communicate in space using radio waves. They use radios to talk to mission control on Earth and to communicate with each other inside the spacecraft. They can also use video conferencing and email for communication purposes.


What kind of radios are used on the space shuttle?

The space shuttle used a variety of radios for communication, including VHF, UHF, S-band, and Ku-band radios. These radios allowed communication with mission control on Earth, other spacecraft, and astronauts during spacewalks. Each radio had specific functions and frequencies for various aspects of the mission.


How do astronauts communicate if radios are BROKE?

If radios are broken, astronauts can use backup communication systems, such as hardwired intercoms or visual signals, to communicate with each other. They might also use written messages or gestures to convey critical information. In emergencies, they could rely on pre-established protocols and signals to ensure safety and coordination. Additionally, they could attempt to repair the communication equipment if feasible.


Has anyone ever survived in space?

No human has ever survived in the vacuum of space without a spacesuit. However, there have been instances where astronauts have made it back to their spacecraft or station after experiencing a spacewalk or other accidents. The lack of oxygen and extreme temperatures in space make it impossible for unprotected individuals to survive.
