A spacecraft
rocket
I would call that a Space Shuttle.
an airplane with no engine, it's carried up by a tow plane, released and glides back to earth
The Space Shuttle has enough residual fuel on board to fire it's main engines just long enoughto orient to the correct position and move out of orbit. From that point on, gravity takes over, and the shuttle glides all the way to the ground - one it leaves orbit, no engine power is used at all.
A trip from Earth to some orbit in space, and back to Earth.
the earth's gravitational pull is just strong enought to keep it in orbit, but not strong enought, at that distance, to pull it back to earth
Gagarin made one orbit of the earth in 108 minutes before coming back home.
Stair glides can cost anywhere from $70 to 150 and are very useful for carrying heavy objects. This will save your back a lot of future trouble. Stair glides are thin and light weight for ease of use and compact storage.
Not true. An object can fall back to earth, orbit (circle) the earth, or- if moving fast enough, leave the orbit of the earth and go elsewhere. We have sent probes to other planets- they are not circling the earth.
it lets you orbit around space and go back to earth safely
Easy the shuttle that is currently in orbit is going about 25,405 feet per second (17,322 statute miles per hour). In order to get back to Earth the shuttle will fire a In order to return to earth, the shuttle fires its Orbital Manuevering Engines (OMS) in the direction opposite to its orbit, also known as a "de-orbit burn" . It only slows down by about 200 m.p.h. in order to begin "falling" back to earth.
Satellites stay in orbit due to a balance between their forward motion, which keeps them moving forward, and the gravitational pull of the Earth, which pulls them inward. This balance creates a circular path around the Earth called an orbit. If a satellite were to lose its forward motion or if the gravitational pull were to increase, it would fall back to Earth.
