Rocket Lab’s Electron rocket called “PREFIRE and Ice,” is vertical on the pad awaiting liftoff at Launch Complex 1 in Mahia, New Zealand, ahead of NASA’s PREFIRE (Polar Radiant Energy in the Far-InfraRed Experiment) mission Wednesday, June 5, 2024. The mission, the second of two launches for NASA’S PREFIRE, features two identical 6U CubeSats in asynchronous, near-polar orbits, will study how much of Earth’s heat is lost to space from the Arctic and Antarctica.

Rocket Lab’s Electron rocket called “PREFIRE and Ice,” lifts off from Launch Complex 1 in Māhia, New Zealand at 3:15 p.m. NZST Wednesday, June 5, 2024 (11:15 p.m. EDT, Tuesday, June 4), on the second of two launches for NASA’s PREFIRE (Polar Radiant Energy in the Far-InfraRed Experiment). 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.

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).
