TESS (Transiting Exoplanet Survey Satellite)

This illustration of NASA's TESS shows the spacecraft in shades of blue. The multi-sided, cylindrical shaped main body of the satellite has two solar array "wings," each extending out from the sides of the satellite which is attached to an open, cone shaped bottom piece. Nestled inside the cone are four squares which show the relative positions of TESS’s cameras.
