About the size of a briefcase, the CubeSat was built to test new technologies but exceeded expectations by spotting a planet outside our solar system.

PASADENA, Calif. (NASA PR) — Long before it was deployed into low-Earth orbit from the International Space Station in Nov. 2017, the tiny ASTERIA spacecraft had a big goal: to prove that a satellite roughly the size of a briefcase could perform some of the complex tasks much larger space observatories use to study exoplanets, or planets outside our solar system. A new paper soon to be published in the Astronomical Journal describes how ASTERIA (short for Arcsecond Space Telescope Enabling Research in Astrophysics) didn’t just demonstrate it could perform those tasks but went above and beyond, detecting the known exoplanet 55 Cancri e.

PASADENA, Calif. (NASA/JPL-Caltech PR) — The first briefcase-size CubeSats to journey to another planet have been honored for their role in NASA InSight’s successful Mars landing. The American Institute of Aeronautics and Astronautics (AIAA) bestowed their Small Satellite Mission of the Year award to Mars Cube One, or MarCO, Aug. 8, 2019, at the annual Small Satellite Conference in Logan, Utah.
