Today, I am going to tell you how long does it take to get into space?. The challenge to every space launch is getting the spacecraft off the ground in the first place.
It takes a lot of energy to push back against the Earth’s gravitational attraction. But once you’ve begun – you’re going to move up quite rapidly.
So, how long does it take to travel into space?
Firstly, let’s definite what “space” is. If we’re talking about the end of the Earth’s atmosphere, it’s usually regarded to be roughly 100km (62 miles) above. This is called the Karman Line. It signifies you’ve gone through the Thermosphere and are now inside the Exosphere.
For a little background, the International Space Station is circling the planet at between 435km (205 miles) and 435km (270 miles) of height.

Getting into space is a rather tough journey – and it takes a physical and emotional toll on astronauts.
“If you think about it, we’re accelerating a 4-1/2 million pound system from zero miles per hour to its orbital velocity of 17,500 miles per hour in that 8-1/2 minutes. So it’s a heck of a journey for the astronauts,” remarked Mike Leinbach, a launch director at NASA.
“They normally feel approximately three times the force of gravity for much of the climb, and once we reach orbit when the main engines stop off, they go from that three-G acceleration to zero acceleration nearly quickly, and that’s when they become weightless on rotation.
Depending on where you’re heading in space, it may be a relatively rapid journey. If you’re born into Earth’s backyard, you’ll be traveling anywhere from a few hours to a few days. It’s when you start looking at the distance between Earth and other planets that you start to comprehend exactly how enormous outer space is:
- International Space Station: 248 miles from Earth. This journey may be performed within a day.
- Earth’s Moon: 238,900 miles from Earth. This journey takes roughly 3 days.
- Venus, our nearest neighboring planet: 27,900,000 kilometers from Earth. This journey takes 3 months.
- Mars, a recent priority for space travel: 46,500,000 kilometers from Earth. This journey takes up to a year.
- Neptune, the last planet in our solar system: 2,697,000,000 miles from Earth. This journey takes 12 years.
- And that’s just inside our solar system! The Voyager 1 spacecraft was the first man-made object to breach that limit, taking 36 years to complete.
Staying in orbit
Once astronauts are in orbit and onboard the space station, they have to maintain it running at a specific speed to remain up there.
Otherwise, you start having space stations showering down on the planet.
The ISS is traveling at 28,163 kph (17,500mph) in orbit around the Earth.
Of course, the astronauts on board won’t feel this speed – the only indicator they have is gazing down to see planet Earth revolving under them.
Will average people get to travel into space?
One day – but probably not for a long time.
Amusingly, one US-based start-up business has an ambitious proposal to launch a “luxury hotel” into low-Earth orbit.
The “Aurora Station” will provide space travelers an excellent perspective of the planet of Earth and is expected to be an “affordable” method for folks to explore space.
Of course, with a twelve-night stay onboard beginning at roughly $9.5 million (£6.8 million), we’d take issue with the inexpensive aspect.
“We are launching the first-ever cheap luxury space hotel,” said Frank Bunger, the CEO, and creator of Orion Span – the start-up behind the proposal.
Speaking at the Space 2.0 Summit in San Jose, California, Bunger revealed that the business was constructing the hotel itself and that, when done, it’ll be around the size of a big private airplane.
