WASHINGTON (NASA PR) — While we are disappointed in the loss of the two TROPICS CubeSats, the mission is part of NASA’s Earth venture program, which provides opportunities for lower-cost, higher risk missions. Despite a loss of the first two of six satellites, the TROPICS constellation will still meet its science objectives with the four remaining CubeSats distributed in two orbits.  With four satellites, TROPICS will still provide improved time-resolved observations of tropical cyclones compared to traditional observing methods.

The second stage of an Astra Space Rocket 3.3 rocket failed less than a minute before planned shutdown on Sunday, sending two NASA TROPICS mission satellites plunging into the atmosphere instead of entering orbit.

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.

CAPE CANAVERAL SPACE FORCE STATION, Fla. (NASA PR) — Astra Space Inc. is targeting no earlier than June 12, pending issuance of a launch license from the Federal Aviation Administration, for the first launch of NASA’s Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats (TROPICS), a constellation of six CubeSats. Two CubeSats, each about the size of a loaf of bread, will launch aboard Astra’s Rocket 3.3 from Space Launch Complex 46 at Cape Canaveral Space Force Station in Florida.
