Space does have a smell.
Space has a smell that is like gunpowder, sulfur, ozone and a faint acid smell.
We can't smell space directly, because our noses don't work in a vacuum.
However the astronauts aboard the ISS have reported that they notice a metallic aroma – like the smell of welding fumes – on the surface of their spacesuits once the airlock has re-pressurized.
Life in space is similar to life on earth however if yo go out into space you have to wear a space suit and other times you have to be in the space shuttle and there's also no gravity to hold you down.
Space is very dangerous – and without protection, people would not be able to survive there.
In space, there's no air – so you couldn't breathe. It's cold – so you'd freeze.
And there's lots of nasty radiation (from the Sun, and from the rest of the Universe), so you'd get really, really bad sunburn.
The only significant differences from living on Earth are that they operate in the confined space of the Space Shuttle orbiter cabin and that they, and all objects inside the cabin, float.
Because of microgravity on the Space Shuttle, some jobs, like handling tools and fluids, become more difficult.
There have been several people that have died in space.
There have been at least 18 deaths in space which include preparation for entry in space and those in space and some on return to earth from 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.
