No, it is very rarefied. On average it is about 1 atom of hydrogen per cm^3 in interstellar space.

Yes... Are you really that thick...
Equipment sent into space like satellites require thick radiation shielding due to a lack of an atmosphere. In space, radiation exposure is considerably higher than on Earth.
A typical demising wall for retail space is usually around 4 to 6 inches thick. This thickness provides enough sound insulation and fire protection while also allowing for efficient use of space.

They need to wear something that is thick and something that is a space suit... they for sure need to put their pee on their face.
The atmosphere varies but is from 100 miles to 120 miles thick.
you would need a space suit....
Propellers only work in a thick atmospheres, so at a certain height they stop working. This would make it impossible for the space shuttle to go into outer space.
Mercury doesn't have much of an atmosphere. The atmospheric pressure there is a trillion times less than the pressure on earth. It is made up of 42% oxygen, 29% sodium, 22% hydrogen, 6% helium, 0.5% potassium, and trace amounts of argon, nitrogen, carbon dioxide, water vapor, xenon, krypton, and neon.
