TROPICS will study tropical cyclones as part of NASA's Earth Venture Class missions, which select targeted science missions to fill gaps in our overarching understanding of the entire Earth system.
Rocket Lab has completed the first of two dedicated Electron launches to deploy a constellation of tropical cyclone monitoring satellites for NASA.
The ‘Rocket Like a Hurricane’ launch lifted-off on May 8 from Rocket Lab Launch Complex 1 on New Zealands Mahia Peninsula deploying two of the four CubeSats that comprise the TROPICS constellation (Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats). TROPICS will monitor the formation and evolution of tropical cyclones, including hurricanes, and will provide rapidly updating observations of storm intensity.
The constellation, which is part of NASA’s Earth System Science Pathfinder Programme, requires launch to 550km altitude and inclination of about 30 degrees. Each pair of CubeSats must be launched to two specific orbital planes that are equally spaced 180 degrees opposite to maximise the temporal resolution. All four TROPICS satellites need to be deployed into their operational orbit within a 60-day period, a mission requirement made possible with a small dedicated launch. With the first batch of TROPICS CubeSats now in orbit, the second launch, called ‘Coming to a Storm Near You,’ is expected to launch on another Electron rocket in approximately two weeks from Launch Complex 1.
Rocket Lab founder and CEO Peter Beck said: “The TROPICS constellation has the real potential to save lives by providing more timely data about storm intensity and providing advance warning to those in storm paths, so it’s an immense privilege to have deployed these spacecraft to their precise orbits before the upcoming storm season. We’re grateful to the NASA team for entrusting us with such a critical mission and we look forward to completing the constellation with the second Electron launch in the coming days.”
Ben Kim, TROPICS program executive for NASAs Earth Science Division, added: “We are extremely proud of all our partners, including MIT Lincoln Labs, Blue Canyon Technologies, KSAT, and Rocket Lab for successfully executing on this first launch. We look forward to the entire constellation being on-orbit to realise the benefits for the agency, as well as for our colleagues around the world.”
‘Rocket Like a Hurricane’ was Rocket Lab’s fourth mission for 2023 and the company’s 36th Electron mission overall. It brings the total number of satellites launched to orbit by Rocket Lab to 161.
