yes if not they suffocate unless they're in an airlock
No, only when they leave the space shuttle or whichever vehicle they have traveled in.
Generally, yes. Those sensors are often included in the clothing worn under the space suit, so that mission control can monitor the astronauts all the time, even when they aren't wearing their space suits.
No, they only have to wear these when outside the pressurized environment of the spacecraft or during periods when the spacecraft may become compromised.
Astronauts communicated on the moon using radio transmissions through their space suits. They spoke into a microphone inside their helmets, which transmitted their voices to their fellow astronauts and mission control on Earth. The radio transmissions allowed for clear communication despite the challenges of being in space suits and helmets.
No you can take it off for a wee while but only for a short space of time!!
Space craft and space suits have climate control systems. In a space suit, astronauts have an undergarment with small tubes running through it. Water is pumped through these tubes to control the temperature. Typically, keeping warm is NOT the problem for astronauts, they tend to overheat all too easily. Cooling off is a bigger problem for astronauts.
Astronauts use Extravehicular Mobility Units (EMUs) to work outside of the space station. These suits are equipped with life support systems, communications gear, and tools needed for spacewalks. Additionally, astronauts are tethered to the space station to prevent them from floating away into space.
They don't change clothes as they have to wear their space suit all the time.
No only in space. Two reasons first space is almost zero kelvin and they would die instantaneously and second there is no air in space. while inside the shuttle or whatever there staying in there is air bathrooms food water and above all its not almost zero kelvin.
There is not even a little air to breathe on the moon. There is no oxygen at all. This is why astronauts must wear space suits with self contained breathing equipment.
No. In the past spacesuits have had food inside and all spacesuits have drinking water in them. But, neither food nor water can go through the suits when they are pressurized.
That's an easy one; it's on the tv all the time. You must not be from the USA. It's NASA - National Aeronautics and Space Administration.
