NASA Statement on Launch Failure, Loss of TROPICS Spacecraft

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.

Astra Space Scheduled to Launch NASA TROPICS Mission on Sunday

Astra Space is scheduled to launch NASA’s TROPICS-1 mission on Sunday, June 12 from Cape Canaveral Space Force Station in Florida. The launch window opens at 12 p.m. EDT. A livestream of the launch will begin at T-30 minutes: http://astra.com/livestream#AdAstra

Astra’s Rocket 3.3 will launch the first two of six small Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats (TROPICS) spacecraft 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.

Failure Analysis Committee Identifies Propellant Leak as Cause of GSLV Failure

BENGALURU, India (ISRO PR) — The GSLV-F10/EOS-03 Mission lifted-off normally from Sriharikota on August 12,2021 at 0543 hrs after a smooth countdown of 26 hours. In the flight, the performance of the first stage (GS1), the strap-on stages (L40) and the second stage (GS2) were satisfactory and in accordance with the pre-flight predictions. However, the onboard computer aborted the mission at 307 seconds into the flight leading to mission failure.
