Rocket Lab canceled today’s launch attempt due to LOx temperatures being out of bounds for flight, but the resolution is well underway for the next attempt.

After assessing the weather, we are targeting no earlier than Wednesday, 5 June NZST, for the launch of PREFIRE and Ice, the second of two climate launches for NASA.

Launch Date: June 1, 2024 (NZST)
Launch Time: May 31, 11:13 p.m. EDT / June 1, 0313 UTC, 05:13 CEST
Launch Status: Announced & Scheduled

Launch Provider: Rocket Lab, USA
Launcher System: Electron Rocket
Mission: PREFIRE and Ice
Contractor: NASA
Launch Location: Launch Complex-1 - Mähia Peninsula, New Zealand

NASA and Rocket Lab are targeting Saturday, June 1 (UTC), to launch the second CubeSat for the agency’s PREFIRE (Polar Radiant Energy in the Far-InfraRed Experiment) mission. The launch window opens at June 1, 3:13 p.m. NZST, 0313 UTC, 05:13 CEST (11:13 p.m. EDT - May 31)

The first satellite successfully launched on 7:41 p.m. NZST May 25 (3:41 a.m. EDT) on an Electron rocket, called “Ready, Aim, PREFIRE,” from Launch Complex 1 in Māhia, New Zealand. Rocket Lab is now processing the second Electron rocket, called “PREFIRE and Ice,” for launch also from Launch Complex 1 in New Zealand.

These small PREFIRE satellites will fill a gap in our understanding of how much of Earth’s heat is lost to space from the polar regions. The mission will enable researchers to systematically study the planet’s heat emissions in the far-infrared – with 10 times finer wavelength resolution than any previous sensor, and provide clues about sea ice loss, icesheet melting, and a warming Arctic.

NASA and the University of Wisconsin-Madison jointly developed the PREFIRE mission. The agency’s Jet Propulsion Laboratory, located in Southern California, manages the mission for NASA’s Science Mission Directorate and provided the spectrometers. Blue Canyon Technologies built the CubeSats, and the University of Wisconsin-Madison will process the collected data.

NASA’s Launch Services Program selected Rocket Lab to launch both spacecraft as part of the agency’s VADR (Venture-class Acquisition of Dedicated and Rideshare) contract. CubeSats like PREFIRE serve as an ideal platform for technical and architecture innovation, contributing to NASA’s science research and technology development.
