Citing "urgent" hurricane-tracking satellite needs, NASA is on the hunt for new rockets after a launch effort failed to deliver two cubesats to space in June.
NASA is asking more companies to bid for launching its TROPICS satellite line in 2023 after its initial provider, Astra, lost a rocket carrying two TROPICS cubesats during the debut launch on June 12. (The cause remains under investigation.)
NASA officials say the TROPICS launch pivot is needed to for a "timely" launch (opens in new tab) of the cubesat constellation. September saw several huge hurricanes or intense tropical storms (like Hurricane Ian) slam into parts of Canada, the United States and Puerto Rico. Similar storms continue to intensify worldwide amid climate change, making the need for these satellites a pressing one.
To get TROPICS in orbit by 2023, NASA said it will turn to 13 companies preapproved (opens in new tab) under a commercial launch services contract, known as Venture-Class Acquisition of Dedicated and Rideshare (VADR).
"The VADR contract allows the 13 companies selected this year to compete for the rebid of the TROPICS launch services, giving the agency and external stakeholders the ability to use TROPICS data sooner," agency officials said in the statement.
TROPICS, which stands for Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats, aims to allow researchers to view evolving tropical cyclones once an hour, far more frequently than is currently possible with weather satellites in orbit.
Astra's Rocket 3.3 that failed to launch TROPICS has had several failures during recent attempts, prompting the company to cancel that rocket line in August to focus on an improved version, called Rocket 4.0.
Once Rocket 4.0 is ready, NASA and Astra have modified their launch services contract "for the launch of comparable scientific payloads," NASA officials said. Prior to the launch failure, Astra had been selected in 2021 for three TROPICS launches upon the now-canceled Rocket 3.3.
