  2. Lifting gas - Wikipedia

    en.wikipedia.org/wiki/Lifting_gas

    A balloon can only have buoyancy if there is a medium that has a higher average density than the balloon itself. Balloons cannot work on the Moon because it has almost no atmosphere. [15] Mars has a very thin atmosphere – the pressure is only 1 ⁄ 160 of earth atmospheric pressure – so a huge balloon would be needed even for a tiny lifting ...

  3. Helium - Wikipedia

    en.wikipedia.org/wiki/Helium

    Helium liquifies when cooled below 4.2 K at atmospheric pressure. Unlike any other element, however, helium remains liquid down to a temperature of absolute zero. This is a direct effect of quantum mechanics: specifically, the zero point energy of the system is too high to allow freezing. Pressures above about 25 atmospheres are required to ...

  4. Ceiling balloon - Wikipedia

    en.wikipedia.org/wiki/Ceiling_balloon

    On the opposite side of the cabinet is space to store balloons, string and pibal lights. The gas used to fill the balloon is helium or hydrogen. Because of its low cost ceiling balloons are often filled with hydrogen gas, but sometimes helium is used. The balloon is attached to the inflation nozzle and a piece of string is wound around the neck.

  6. Weather balloon - Wikipedia

    en.wikipedia.org/wiki/Weather_balloon

    A weather balloon, also known as a sounding balloon, is a balloon (specifically a type of high-altitude balloon) that carries instruments to the stratosphere to send back information on atmospheric pressure, temperature, humidity and wind speed by means of a small, expendable measuring device called a radiosonde.

  9. High-altitude balloon - Wikipedia

    en.wikipedia.org/wiki/High-altitude_balloon

    High-altitude balloons or stratostats are usually uncrewed balloons typically filled with helium or hydrogen and released into the stratosphere, generally attaining between 18 and 37 km (11 and 23 mi; 59,000 and 121,000 ft) above sea level. In 2013, a balloon named BS 13-08 reached a record altitude of 53.7 km (33.4 mi; 176,000 ft). [1]
