Rocket Lab's Electron successfully deploys NASA's TROPICS cubesats for hurricane tracking.

Rocket Lab's Electron rocket has launched a second pair of NASA TROPICS cubesats, which will join two others in the four-satellite TROPICS constellation. The cubesats carry microwave radiometers that NASA scientists will use to monitor the formation of tropical storms, collecting data at an hourly cadence. The launch was the fifth this year by Rocket Lab, which has projected up to 15 Electron launches this year, including both orbital missions and HASTE flights.
