What would happen if you fell from space?

You would still die of course, but it would be by asphyxiation. Your blood holds enough oxygen for about 15 seconds of brain activity. After that you’d black out, with complete brain death following within three minutes.

How are spacecraft protected from debris?

Passive protection generally consists of shielding a spacecraft or its critical components. Active protection schemes use sensors to provide advanced warning of impact and then protect critical components or move the spacecraft to avoid the potential impact.

Has debris hit the ISS?

Multiple dents and dings on the ISS exterior show that the station has been hit with debris before; in June 2021, a piece of debris even plowed a hole into one of the station’s robotic arms — a metal apparatus with a diameter of just 14 inches (35 cm).

Does the ISS get hit by debris?

Space debris has become a major concern for all satellites orbiting the Earth, not just the football-field-sized ISS. In May this year there was a hit: a tiny piece of space junk punched a 5mm hole in the ISS’s Canadian-built robot arm.

Why can’t we re-enter space with spacecraft?

Spacecraft re-entry is tricky business for several reasons. When an object enters the Earth’s atmosphere, it experiences a few forces, including gravity and drag. Gravity will naturally pull an object back to earth. But gravity alone would cause the object to fall dangerously fast.

What happens when a spacecraft re-enter Earth’s atmosphere?

Spacecraft re-entry is tricky business for several reasons. When an object enters the Earth’s atmosphere, it experiences a few forces, including gravity and drag. Gravity will naturally pull an object back to earth. But gravity alone would cause the object to fall dangerously fast. Luckily, the Earth’s atmosphere contains particles of air.

How dangerous is space debris to spacecrafts?

Since both the debris and spacecraft are traveling at extremely high speeds (approximately 15,700 mph in low Earth orbit), an impact of even a tiny piece of orbital debris with a spacecraft could create big problems.

What happens when a satellite is launched into space?

Once the rocket reaches an altitude near the satellite’s orbit height, the satellite is ejected from the rocket’s nose cone and the rocket falls back to Earth, burning up upon reentering our atmosphere (so don’t worry about getting hit on the head with bits and pieces of used rockets).
