What happens if the ISS breaks?
The ISS is built in compartments that can be sealed from each other. The problem compartment would almost certainly be evacuated and closed off before all the air was lost. This has never happened.
How many dead astronauts are in space?
As of 2020, there have been 15 astronaut and 4 cosmonaut fatalities during spaceflight. Astronauts have also died while training for space missions, such as the Apollo 1 launch pad fire which killed an entire crew of three. There have also been some non-astronaut fatalities during spaceflight-related activities.
What happens if there is a fire on the ISS?
If a fire were to occur on the ISS, the astronauts would become firemen and follow a three-step response system. First, they would turn off the ventilation system to slow the spread of fire. Next they would shut off power to the effected unit. Finally astronauts would use fire extinguishers to put out the flames.
What would happen if a spaceship door opened?
Space is a vacuum and presumably the inside of the spacecraft would be pressurized and filled with oxygen. So opening a door would force the two spaces to equalize. Space is obviously much larger so all the oxygen would get immediately sucked out of the spacecraft along with anything not strapped down.
What happens to your body when you go to space?
In fact, your face will feel and look swollen. Except for the occasional headache and congestion, astronauts aren’t bothered by this fluid shift. Some astronauts feel dizzy and have an upset stomach during the first few days of a space flight as they get used to zero gravity. This feeling usually goes away after three or four days.
What is it called when an astronaut works outside of space?
Working outside of a spacecraft while in space is called an extravehicular activity, an EVA or a spacewalk. The white spacesuit an astronaut wears during a spacewalk is called the extravehicular mobility unit, or EMU.
What happens to space suits before and after a shuttle mission?
Just before a shuttle mission, the suits designated for flight are tested, cleaned and packed at NASA’s Johnson Space Center in Houston. Then they are flown to NASA’s Kennedy Space Center in Florida and stowed on the shuttle orbiter. After each flight, the suits are returned to Johnson for postflight processing and reuse.
What conditions do astronauts face when they walk in space?
Space shuttle astronaut Bruce McCandless became the first astronaut to maneuver about in space untethered. He wore a jetpack-like device called the Manned Maneuvering Unit, or MMU. Spacewalking astronauts face a wide variety of temperatures. In Earth orbit, conditions can be as cold as minus 250 degrees Fahrenheit.
