NASA and Rocket Lab are targeting 9 p.m. EDT, Sunday, April 30 (1 p.m. New Zealand Standard Time, Monday, May 1), to launch two storm tracking CubeSats into orbit.
The agency’s TROPICS (Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats) mission has a two hour launch window from Launch Complex 1 Pad B in Māhia, New Zealand.
Rocket Lab will provide live coverage beginning approximately 20 minutes before launch. Coverage will air on NASA Television, the NASA app, and the agency’s website, as well as the Rocket Lab website.
TROPICS is a constellation of four identical CubeSats designed to observe tropical cyclones from low Earth orbit, making observations more frequently than current weather tracking satellites. Both payloads, each carrying a pair of CubeSats, will launch on a Rocket Lab Electron rocket.
A second launch from Rocket Lab with two additional CubeSats is targeted for Tuesday, May 16 EDT, with exact launch times contingent on the date and time of the first launch.
TROPICS will study tropical cyclones as part of NASA’s Earth System Science Pathfinder Program and should increase understanding of the processes driving rapid changes in storm structure and integrity. NASA plans to have the CubeSats distributed evenly in two low Earth orbital planes about 340 miles (550 kilometers) above the Earth’s surface. TROPICS has the potential to provide roughly hourly observations of a storm’s precipitation, temperature, and humidity, compared to about every six hours with current satellites. Gathering data more frequently can help scientists improve weather forecasting models.
