Update: The launch aboard an Astra Space Rocket 3.3 booster failed after the vehicle’s second stage shut down prematurely on Sunday. NASA said in an update that the TROPICS constellation can still improve the monitoring of tropical cyclones with four satellites. Astra Space has the contract to launch the four additional TROPICS spacecraft on two launches.

NASA is launching the first two of six small satellites no earlier than June 12 that will study the formation and development of tropical cyclones almost every hour – about four to six times more often than is possible with current satellites. This is the first of three CubeSat launches for NASA’s Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats (TROPICS) mission. The remaining satellites will be placed into their orbits during two subsequent launches this year. If successful, the TROPICS satellites will be spread across three orbital planes to cover more of the globe more frequently.
