Astronauts must have good airflow around them when they sleep, otherwise they, “…could wake up oxygen-deprived and gasping for air, because a bubble of their own exhaled carbon dioxide had formed around their heads.”
A Soviet probe, “Luna 15”, crashed into the surface of the moon while Buzz Aldrin and Neil Armstrong were still on it.
Scientists are working on a nuclear fusion rocket which could reach Mars in 30 days.

If you were were exposed to outer space without a suit, after about 15 seconds, you would be blue, bloated, and in an unresponsive stupor, but not dead. If they got you back inside and gave you oxygen within about 90 seconds, you’d likely make a complete recovery with only minor injuries.
The first “emergency” aboard Apollo 13 was when astronaut John Swigert radioed Huston because he had forgotten to file his income taxes. Flight Director Glynn Lunney assured that Americans out of the country got a 60-day extension on filing.
