A Rocket Lab Electron rocket is poised for launch atop Pad B, Launch Complex 1, in Māhia, New Zealand. Launch time is May 8 at 1 p.m. New Zealand time (May 7 at 9 p.m. EDT). The Electron rocket is carrying two NASA CubeSats designed to study tropical cyclones, including hurricanes and typhoons. NASA’s Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats (TROPICS) CubeSats will provide data on temperature, precipitation, water vapor, and clouds by measuring microwave frequencies, providing insight into storm formation and intensification.
