Why pencils are not used in space?

To understand why NASA was so keen on a workable space pen, you have to understand that the pencil is not suited for space travel. The problem is that they have a habit of breaking, shattering, and leaving graphite dust behind. The wood, too, can make it a serious fire risk in the pressurized, oxygen-rich capsule.

Why is fire in space bad?

Fire is a different beast in space than it is on the ground. When flames burn on Earth, heated gases rise from the fire, drawing oxygen in and pushing combustion products out. In microgravity, hot gases don’t rise. Space flames can also burn at a lower temperature and with less oxygen than fires on Earth.

What happens to astronauts feet in space?

“The calluses on your feet in space will eventually fall off,” astronaut Scott Kelly revealed in a Reddit AMA. “So, the bottoms of your feet become very soft like newborn baby feet

What happens if you get sick in space?

Zero gravity can change a lot of normal bodily functions. One effect it has is to make the fluids inside the body float, which confuses the inner ears and makes them unable to tell up from down. This causes space adaptation syndrome (SAS), a common illness that’s kind of like seasickness in space.

What happens if you sneeze in space?

A cough or sneeze on Earth blasts infectious particles from 3 to 6 ft. (1 to 2 m) away before gravity takes over and they fall out of the air. In space, they float everywhere. When they do land, they don’t settle in some safe, out of the way place, because in a spacecraft there is no out of the way.

What happens if you get a cut in space?

In space, blood can splatter even more than it usually does on Earth, unconstrained by gravity. Or it can pool into a kind of dome around a wound or incision, making it hard to see the actual trauma. (Fun fact: If you are bleeding more than 100 milliliters per minute, you are probably doomed
