When you go to space, can you get out hydrogen from the sun? How do you get hydrogen on earth?
Answer 1:

The sun continually blasts hydrogen in all directions in the form of solar wind, which could be collected. Otherwise it is very hard to get the sun's material, due to the sun's immense temperature and vastly more powerful gravity than anything else in the solar system.

Hydrogen on Earth is easy to get: water is two parts hydrogen and one part oxygen. Split these up with electric current or ultraviolet light and you get hydrogen gas - and oxygen gas.
