Scientific Balloon Begins Antarctic Ascent

A white scientific balloon rises into the bright blue sky above snowy Antarctica. The sky and the balloon take up most of the image, with the ground only being a small white stripe at the bottom of the photo. The balloon has a long white "tail" with orange and black portions.

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.
