Astra has completed final liquid oxygen conditioning and resumed countdown for the launch of its Rocket 3, carrying two of NASA’s TROPICS CubeSats. Liftoff currently is scheduled for today at 1:43 p.m. EDT.  

Astra has paused the countdown of the launch of its Rocket 3, carrying two of NASA’s TROPICS CubeSats, to complete final liquid oxygen conditioning on the vehicle. Upon completion, the team will set a new launch time for TROPICS-1.

Each TROPICS satellite is identical – a 3U CubeSat about the size of a loaf of bread and weighing about 12 lbs.   The TROPICS CubeSat payload is a spinning microwave radiometer with highly integrated, compact microwave receiver electronics.   TROPICS satellite measures microwave frequencies ranging from about 90 to 205 gigahertz, which can monitor …
