The Editor's Corner

Steve Platnick, EOS Senior Project Scientist

On May 7, 2023, at 9:00 PM Eastern Daylight Time (EDT), Rocket Lab successfully launched an Electron rocket from Launch Complex 1 in New Zealand, which carried the first two 3U CubeSats1 of the Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats (TROPICS) mission into orbit. Following launch, the rocket’s kick stage, which is normally used on Electron launches to circularize the orbit, performed the inclination change needed to place the payload in the required 550-km orbit at an inclination of 32º. The two 3U CubeSats were released 35 minutes after liftoff, and then—after a tense 20 minutes—the successful deployment was confirmed when a ground station acquired the signal from both of the satellites. A second Electron launch took place May 26, 2023, at 11:46 PM EDT—from the same location and following a similar sequence of events—and successfully deployed two more 3U CubeSats to complete the TROPICS constellation.
