They need to reach escape velocity (about seven miles per second) to break away from Earth's gravity. (Anything traveling more slowly will eventually fall back to Earth.)
A spacecraft takes off using rocket propulsion, where engines generate enough thrust to overcome Earth's gravity. The spacecraft accelerates vertically until it reaches a high enough velocity to escape the Earth's atmosphere and enter orbit or travel to another celestial body.
The orbiter would detach and land in the ocean shortly after take off.
As long as you are inside the spacecraft or inside the habitat, or on the Earth, you're probably fine. If you take off your spacesuit in space, you will die within seconds.
A spacecraft or rocket is used to lift off from a planet on a journey into space. The rocket engines provide the necessary thrust to overcome Earth's gravity and propel the spacecraft into space.
It takes about 3 days (72 hours) for a spacecraft to travel from Earth to the Moon.
It takes 3-4 days to get to the moon from Earth by spacecraft
22.2 minutes
NASA's Apollo and Space Shuttle spacecraft all launched from Cape Canaveral, Florida.
The Apollo spacecraft took 3 days to travel from the Earth to the moon.
It would take over 16,000 Earth days, or around 44 Earth years, for a spacecraft to travel from Earth to Neptune at its average distance from Earth. The actual time would depend on the speed and trajectory of the spacecraft.
Traveling at the speed of light, it would take a spacecraft 40 years to reach a star located 40 lightyears away from Earth.
Spacecraft take off using rocket engines that generate thrust to lift them off the ground. They can land using techniques such as parachutes, airbags, or propulsive landing systems, depending on the design of the spacecraft and the requirements of the mission.
