Why does it take so long to dock to the ISS?

Everything in our solar system revolves around the sun, so objects are never in a fixed location. That means spaceships can’t take a direct path to their destination; they need to go in a spiral so that they eventually cross paths with the orbit of the planet or space station they’re trying to reach.

How long does it take for astronauts to get to the ISS?

It can take anywhere from 6 hours to 3 days to get to the International Space Station, depending on the spacecraft and mission profile. It took the Apollo astronauts about three days to get to the Moon.

Why does traveling in space take so long?

Another reason space missions take a long time is that we don’t have rockets that get us through space very quickly. That is why the DS1 mission is experimenting with solar ion propulsion, which tries to send small amounts of fuel out very fast, making travel in space faster for the same amount of fuel.

Why is Soyuz faster to ISS?

The spacecraft is boosted into the ISS’s orbit with the help of a series of carefully-orchestrated thruster burns. Since these were spread out over as many as 34 orbital laps, it took the capsule a few days to meet up with the ISS, which travels at a rapid pace of 17,500 miles per hour.
