NASA has developed a 'superpressure' balloon that may be a cheap alternative for a space telescope with Hubble-level quality.

NASA's second-of-its kind high-altitude balloon sprang a leak and is now at the bottom of the Pacific Ocean.

The project, called the Superpressure Balloon-born Imaging telescope (SuperBIT), uses a helium-filled balloon the size of a football field to raise a .5-meter telescope to a 40-kilometer altitude.

Described today at the online National Astronomy Meeting (NAM 2021), the Superpressure Balloon-borne Imaging Telescope (or SuperBIT) is a new kind of astronomical observatory—a low-cost balloon ...
