A super pressure balloon built by students is cruising Earth’s skies to find dark matter
The Superpressure Balloon-borne Imaging Telescope after launch. SuperBIT High altitude balloons have drawn a lot of fire lately. In February, the US military shot down a spy balloon potentially operated by the Chinese government and an “unidentified aerial phenomenon” that was later revealed to likely be a hobbyist balloon. So, when people caught sight of another large balloon in the southern hemisphere in early May, there was concern it could be another spy device. Instead, it represents the future of astronomy: balloon-borne telescopes that peer deep into space without leaving the stratosphere. “We’re looking up, not down,” says William Jones, a professor of physics at Princeton University and head of NASA’s Super Pressure Balloon Imaging Telescope (SuperBIT) team. Launched from Wānaka, New Zealand, on April 15, the nearly 10-foot-tall telescope has already circled...
