How high can hydrogen balloon go?

High-altitude balloons are crewed or uncrewed balloons, usually filled with helium or hydrogen, that are released into the stratosphere, generally attaining between 18 and 37 km (11 and 23 mi; 59,000 and 121,000 ft) above sea level.

Can a balloon go into outer space?

A helium-filled balloon can float very high up into the atmosphere, however, it cannot float up into outer space. The air in Earth’s atmosphere gets thinner the higher up you go. This happens at about a height of 20 miles (32 kilometers) above Earth’s surface. So, this is as far as a helium balloon can rise.

Why don’t we fill balloons with hydrogen?
