Would you be able to hear an explosion in outer space?

Would you be able to hear an explosion in outer space?

To travel to us from outer space, the wave must be able to travel through regions of space which are essentially vacuum (nothing there). Sound cannot do this, as it requires a medium to propagate in, so we would not be able to hear the explosion.

Would a person explode in space?

The vacuum of space will pull the air from your body. So if there’s air left in your lungs, they will rupture. Oxygen in the rest of your body will also expand. You’ll balloon up to twice your normal size, but you won’t explode.

Are explosions silent in space?

The gases from a supernova explosion expand rapidly, and the density will drop off fast. But the basic idea is that you would have to be extremely close to get densities high enough to hear anything. So we won’t ever hear a supernova explosion on Earth, for example. It’s a little sad, but space really is silent.

Can a scream be heard in space?

A: Sound is a mecanical wave, which means that it needs substance to travel through, such as air or water. In space, there is no air, so sound has nothing to travel through. If someone were to scream in space, the sound wouldn’t even leave their mouths.

What would an explosion in space really look like?

An explosion in space would realistically look like a brief spherical burst of light moving outwards, as well as a discharge of energy and material from the exploding object (energy and light can both travel in a vacuum). It would take a moment for the pressure to rebalance from space and for the fuel to be burned up.

Has NASA lost a man in space?

A total of 18 people have lost their lives either while in space or in preparation for a space mission, in four separate incidents. All seven crew members died, including Christa McAuliffe, a teacher from New Hampshire selected on a special NASA programme to bring civilians into space. …

How does a spacesuit protect an astronaut in space?

Like a spacecraft, a spacesuit protects an astronaut from the dangers of space. The spacesuit completely covers a spacewalker’s body. The pieces of the suit interlock so that none of the spacewalker’s skin is exposed to space. Without spacewalks, much of the work that needs to be done in space would not be accomplished.

How are spacesuits on the International Space Station different?

The spacesuit design is different from what you’ll see on the International Space Station. There, astronauts don what is essentially a three-piece suit — leggings on the bottom, a torso unit in the middle and a helmet on the top. But NDX-2 is a single piece that would-be astronauts climb into from the back.

What can a human do without a space suit?

With that being said the WORST thing a human can do in space without a space suit would be to hold their breath. Due to the lack of pressure in space, the oxygen located inside the lungs would expand causing the lungs to rupture inherently causing death.

How long does it take to put a spacesuit on an astronaut?

A spacesuit weighs approximately 280 pounds on the ground – without the astronaut in it. In the microgravity environment of space, a spacesuit weighs nothing. Putting on a spacesuit takes 45 minutes, including the time it takes to put on the special undergarments that help keep astronauts cool.
