Extended mission technology demonstrations using the ASTERIA spacecraft

ASTERIA (Arcsecond Space Telescope Enabling Research In Astrophysics) is a CubeSat space telescope currently operating in low-Earth orbit. It is expected to remain in orbit at least through October 2019. Developed as a
technology demonstration mission under the JPL Phaeton Program for training early-career engineers, ASTERIA has achieved sub-arcsecond pointing stability and milliKelvin thermal stability over 20-minute observations.
