What is the fastest a human has traveled in space?

39,897km/h
The Space Shuttle has an orbital velocity of around 30,000km/h, but the crew of Apollo 10 hold the official record for the fasted manned vehicle when they reached 39,897km/h relative to the Earth on 26 May 1969 during their return from lunar orbit.

Do astronauts grow slower in space?

Scientists have recently observed for the first time that, on an epigenetic level, astronauts age more slowly during long-term simulated space travel than they would have if their feet had been planted on Planet Earth.

Do astronauts experience time differently?

ISS astronauts experience both gravitational and relative velocity time dilation. The relative velocity dilation is stronger than the gravitational one, thus astronauts experience time more slowly than those of us on Earth.

Why do we need more astronauts?

As NASA continues to expand human exploration in our solar system, we will need more than the currently active astronauts to crew spacecraft bound for multiple deep-space destinations. NASA’s astronauts currently work as scientists on the International Space Station—a laboratory that orbits Earth approximately 240 miles above the planet’s surface.

Do astronauts age faster or slower in space?

So depending on our position and speed, time can appear to move faster or slower to us relative to others in a different part of space-time. And for astronauts on the International Space Station, that means they get to age just a tiny bit slower than people on Earth.

What is it like to live in space?

Living in space is not the same as living on Earth. In space, astronauts’ bodies change. On Earth, our lower body and legs carry our weight. This helps keep our bones and muscles strong. In space, astronauts float.

How many people have been to space with NASA?

NASA’s astronaut corps, representing almost all 50 states, has over 300 current and former members. The first astronaut team, comprised of seven men, was selected in 1959. Since then there has been a series of milestones in the history of human spaceflight, including: 1961: Russian Yuri Gagarin was the first human to fly in space.
