ExoCube 2 is a relaunch of the original ExoCube which was launched in early 2015.
ExoCube 2 has undergone a complete redesign of the antenna deployment mechanisms compared
to the original ExoCube, and is a collaboration between Cal Poly SLO, NASA Goddard,
the University of Wisconsin, and the University of Illinois. Cal Poly is providing
the bus design and manufacturing. NASA Goddard is providing the scientific payload
which is a custom mass spectrometer. Both the University of Wisconsin and the University
of Illinois are responsible for collection and interpretation of the payload data
collected. The data in question is the mass and densities of ions located in the exosphere,
which is the uppermost part of our atmosphere at approximately 600km above sea level.
ExoCube 2 is Cal Poly’s 12th CubeSat (CP12) and similarly to its predecessor is a
3U format- its outer dimensions are 10cm x 10cm x 30cm (3.9in x 3.9in x 11.8in). The
satellite has custom payload housing and structure, machined in the Cal Poly shops
by Cal Poly students, as well as student designed electrical boards. It has an advanced
Attitude Determination Control System (ADCS) which includes two deployable gravity
gradient booms with brass tip masses for passive stabilization, magnetic torquers
for de-tumbling, a momentum wheel for increased attitude control, solar angle sensors
to determine the satellite's position, and custom Cal Poly software to process data
from the solar angle sensors. ExoCube 2 is due to launch on a Virgin Orbit test launch
late-2018.
