Astra, the Alameda-based space launch startup that recently announced its intent to go public via a SPAC merger, has secured a contract to deliver six cube satellites to space on behalf of NASA. Astra stands to be paid $7.95 million by the agency for fulfilment of the contract. This will be a key test of Astra’s responsive rocket capabilities, with a planned three-launch mission profile spanning up to four months, currently targeting sometime between January 8 and July 31 of 2022.

The satellites are for NASA’s Time-Resolved Observations of Precipitation Structure and Storm Intensity with a Constellation of SmallSats (TROPICS) mission, which is a science mission that will collect data about hurricanes and their formation, including temperature, pressure and humidity readings. Like the extremely long, tortured-for-an-acronym name of the mission suggests, the data will be collected using a small constellation of satellites, each roughly the size of a shoebox.\
