Is it possible to make a space elevator?
A space elevator is possible with today’s technology, researchers say (we just need to dangle it off the moon) Space elevators would dramatically reduce the cost of reaching space but have never been technologically feasible.
Why is a space elevator impossible?
Historically, the main technical problem has been considered the ability of the cable to hold up, with tension, the weight of itself below any given point. The greatest tension on a space elevator cable is at the point of geostationary orbit, 35,786 km (22,236 mi) above the Earth’s equator.
Can I build a rocket and go to space?
As to your question, yes, it is theoretically possible. In fact, there have been a few amateur made rockets that have reached the Kármán line. The first happened May 17, 2004, by the Civilian Space eXploration Team (CSXT). This is the only known amateur rocket to make it past 100 km.
Has anyone been lost in space?
A total of 18 people have lost their lives either while in space or in preparation for a space mission, in four separate incidents. Given the risks involved in space flight, this number is surprisingly low. The remaining four fatalities during spaceflight were all cosmonauts from the Soviet Union.
What would happen if you tied the moon to the Earth?
If the connection was between the North Pole (or South Pole) of the Earth and the moon, and the rope can rotate around the anchor point on Earth, then absolutely nothing will happen. The moon will continue its path around the Earth and there will be a string between them.
How do we launch satellites and spacecraft into space?
We launch satellites and spacecraft into space by putting them on rockets carrying tons of propellants. The propellants give the rocket enough energy to boost away from Earth’s surface. Because of the pull of Earth’s gravity, largest, heaviest spacecraft need the biggest rockets and the most propellent.
How do satellites stay in orbit around the Earth?
Satellites that orbit close to Earth feel a stronger tug of Earth’s gravity. To stay in orbit, they must travel faster than a satellite orbiting farther away. The International Space Station orbits about 250 miles above the Earth and travels at a speed of about 17,150 miles per hour.
How does the International Space Station stay in orbit?
To stay in orbit, they must travel faster than a satellite orbiting farther away. The International Space Station orbits about 250 miles above the Earth and travels at a speed of about 17,150 miles per hour. Compare that to the Tracking and Data Relay Satellites, which help us get information to and from other NASA missions.
What do you need to launch a rocket to space?
To launch, the rocket needs enough propellants so that the thrust pushing the rocket up is greater than the force of gravity pulling the rocket down. A rocket needs to speed up to at least 17,800 miles per hour—and fly above most of the atmosphere, in a curved path around Earth.
