Rocket Lab’s Electron rocket is vertical on the pad Saturday, May 25, 2024, at Launch Complex 1 in Mahia, New Zealand, loaded with the first of two identical 6U CubeSats for NASA’s PREFIRE (Polar Radiant Energy in the Far-InfraRed Experiment) mission to help close a gap in our understanding of how much of Earth’s heat is lost to space from the Arctic and Antarctica. Liftoff of the first CubeSat launch, which Rocket Lab named “Ready, Aim, PREFIRE,” occurred at 7:41 p.m. NZST (3:41 a.m. EDT).

A Rocket Lab Electron rocket lifts off from Launch Complex 1 in Māhia, New Zealand at 7:41 p.m. NZST (3:41 a.m. EDT) Saturday, May 25, 2024, on the first of two launches which Rocket Lab named “Ready, Aim, PREFIRE,” for NASA’s PREFIRE (Polar Radiant Energy in the Far-InfraRed Experiment) mission. The PREFIRE mission, expected to last at least 10 months, consists of sending two CubeSats to asynchronous, near-polar orbits, to help close a gap in our understanding of how much of Earth’s heat is lost to space from the Arctic and Antarctica.
