What is interstellar gas made of?

The gas between stars is mostly hydrogen and helium scattered at varying densities between the stars in our galaxy and other galaxies. The proportions of the gases are similar to those in the Sun. Interstellar gas supplies the raw material for star formation.

Regarding this, how do rockets work in space without oxygen?

In space, rockets zoom around with no air to push against. What's going on? Rockets and engines in space behave according to Isaac Newton's third law of motion: Every action produces an equal and opposite reaction. When a rocket shoots fuel out one end, this propels the rocket forward - no air is required. Consequently, what does nasa do besides space? NASA does a lot of different things. NASA makes satellites. The satellites help scientists learn more about Earth. NASA sends probes into space.

Accordingly, can you launch a rocket into space from anywhere?

Any American citizen who wants to launch a rocket or other kind of spacecraft into orbit must obtain authorization from the FAA, as would any foreigner who launches within U.S. territory. The FAA regulates the commercial sector's space activities by requiring parties to obtain launch and re-entry licenses. Do they use a compass in space? The compass works on the same principle in space as on earth, given that the compass is situated in a magnetic field. It points to magnetic north of the magnetic field.

What coordinate system is used in space?

NASA uses a spherical Coordinate system called the Topodetic coordinate system. Consider the position of the space shuttle. The first variable used for position is called the azimuth. Azimuth is the horizontal angle of the location on the Earth, measured clockwise from a line pointing due north. Is there a compass for space? As you leave the Earth and move into space the magnetic field will get weaker. Even though the field is weaker, the compass can still align with it meaning that a compass on the International Space Station would still be a reliable guide to the North Pole.

Earth only has a north and south due to its magnetic field created by the rotation of its molten core, and these concepts only apply in a coordinate system. In the context of the universe, however, there's no north or south or up or down.
