rockets are not the only thing that can .
take a magnet for example ,like poles repel thus pushing the object away
So far, technology has only allowed us to travel to space in rockets/space shuttles.
space shuttles were made to be reusable, rockets were used only once
Yes only rockets go through here after it is outer space that is why it is called the exosphere because your exiting earths atmosphere.
The rockets that have been used carry their one oxygen for the combustion. Or they use a fuel that dosn't need to ignite. These latter propellants rely only on Newtons second law.
Thousands if not millions. Not only are there space rockets, but also rockets used in research and war.
There is no such thing as "absolute motion" - neither in outer space, nor anywhere else. Motion must always be specified in relationship to some other object.
Google Earth apparrently can see a gnats whisker ! I'm thinking the only man made thing actually visible from outer space is the Great Wall of China, but I've yet to go into space.....
A possible word for space science ending in -try would be rocketry. Rocketry relates to how rockets work, and rockets are the only thing currently used to travel through space. Rocketry also ends in the suffix -try, so rocketry is a possible word.
Only in outer space
Nothing. That is why they call it outer space. the only things that are out there are stars, rocks, planets and light and darkness
Sound waves travel through matter. The only thing it doesn't travel through is vacuums or outer space.
Rockets provide force that can propel ships forward, even in the near vacuum conditions of space. Propellers can provide force only in a substantial atmosphere.
