Red Bull Stratos was a high-altitude skydiving project involving Austrian skydiver Felix Baumgartner.On 14 October 2012, Baumgartner flew approximately 39 kilometres (24 mi) [1] [2] [3] into the stratosphere over New Mexico, United States, in a helium balloon before free falling in a pressure suit and then parachuting to Earth.

A balloon race that took place in Bremen, Germany, in 2009. A balloon release is a ceremonial event in which a number of hydrogen- or helium-filled balloons are launched into the sky. Balloon releases can be done as a prayer ceremony, to create a photo opportunity, to raise awareness of a cause or campaign, or as a competitive long-distance race.
be re-implanted into the regolith as a result of the Moon's gravity; escape the Moon entirely if the particle is moving at or above the lunar escape velocity of 2.38 km/s (1.48 mi/s), or 5,328 mph (8,575 km/h); be lost to space either by solar radiation pressure or, if the gases are ionized, by being swept away in the solar wind's magnetic field.
Helium is inert - it does not react with other substances or combust - and its atomic number is 2, making it the second lightest element after hydrogen. Rockets need to achieve specific speeds and ...
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]

Here's a breakdown of how and why it all happens. But the science behind a blue sky isn't that easy. For starters, it involves something called the Rayleigh effect, or Rayleigh scattering.
Like Walters, Couch had a BB gun on hand to shoot the balloons in order to initiate descent. After the flight, he developed a way to release helium from the balloons, allowing for a more controlled descent. [10] [23] During a second flight on July 5, 2008, Couch realized his goal of interstate travel when he landed safely in western Idaho. The ...
