Scientific Balloon Begins Antarctic Ascent

A scientific balloon starts its ascent into the air as it prepares to launch carrying NASA’s Payload for Ultrahigh Energy Observations (PUEO) mission. The mission lifted off from Antarctica at 5:56 a.m. NZST, Saturday, Dec. 20 (11:56 a.m., Friday, Dec. 19 in U.S. Eastern Time).

The PUEO mission is designed to detect radio signals created when highly energetic particles called neutrinos from space hit the ice. The PUEO payload will collect data that give us insight into events like the creation of black holes and neutron star mergers. Alongside the PUEO mission are two other balloons carrying calibration equipment sending test signals to help scientists make sure the payload equipment is working correctly when it tries to detect real signals from space. 

Track the balloons in realtime.
