The BLAST high-altitude balloon just before launch on June 12, 2005. 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 1934 the NGS and Air Corps co-sponsored the Explorer, a manned high-altitude balloon capable of stratospheric flight. After the crash of the Soviet Osoaviakhim-1 that nevertheless set an altitude record of 72,178 feet (22,000 m), the sponsors redefined their primary objectives from record-setting to scientific research and tests of new navigation instruments.

The balloon will test changes in aerosols in the stratosphere. One thing scientists, conservationists and researchers are clear on is that solar geoengineering is not a get-out-of-jail card for ...
Zero 2 Infinity (0II∞, sometimes rendered as Zero2Infinity) is a private Spanish company developing high-altitude balloons intended to provide access to near space and low Earth orbit using a balloon-borne pod and a balloon-borne launcher. The company was founded in 2009 by aerospace engineer Jose Mariano López-Urdiales, the current CEO.
Urban Sky was founded in 2019 with the goal of increasing access to the stratosphere, and reducing the cost of remote sensing through balloon miniaturization and new approaches to balloon control. In 2020 Urban Sky began routine stratospheric operations and became the first company ever to reuse a stratospheric balloon. [3] [7]
To test the parachute system, staff at Wright Field built a 200 ft (61 m) high helium balloon with a capacity of nearly 3,000,000 cubic feet (85,000 m 3) that could lift an open gondola and test pilot into the stratosphere. Captain Joseph Kittinger, who was test director for the project, made three ascents and test jumps.
The balloon’s ability to fly and gather intelligence was primarily powered by 16 solar panels, U.S. officials later determined. ... “I think they have a stratospheric balloon program that is ...
