Observing satellite BlueWalker together with SeaSat1. Estimating magnitute around 1.
Satelliet BlueWalker 3 is a prototype satellite for AST & Science's SpaceMobile mobile communications constellation. The satellite will be to test AST & Science's patented technologies for connecting to cellphones in a space environment for their planned SpaceMobile constellation. The 1.5 ton satellite will deploy a 10 m diameter phased array antenna with 64 m2 area consisting of numerous identical sub-antenna modules to connect directly to standard mobile phones.
It is a prototype for the larger operational BlueBird satellites. The first five BlueBird satellites will be similar to BlueWalker 3, while the remaining will be larger.
