QBUS [Stanford Univ.]
QBUS 3 or Discovery is an US 2U-CubeSat designed by the Stanford University participating in the QB50 project.
The QB50 project, which will demonstrate the possibility of launching a network of 50 CubeSats built by Universities Teams all over the world as a primary payload on a low-cost launch vehicle to perform first-class science in the largely unexplored lower thermosphere.
QBUS is a consortium comprised of Stanford University, Johns Hopkins Applied Physics Laboratory, the University of Colorado at Boulder, the University of Michigan and the Universidad del Turabo Puerto Rico, who participate on th QB50 project. The QBUS team will employ four double CubeSats (one from each university with system engineering and project management oversight provided by JHUAPL and USU-SDL), with participating members providing the usual satellite functions (attitude determination and control, uplink and downlink telecommunications, power subsystem including a battery and body-mounted solar cells, on-board data handling and storage by a CPU) as defined by the QB50 Call for Proposals, and the QB50 project providing the standardized sensors for lower thermosphere and re-entry research.
As a payload for QB50, the satellite carries the Ion/Neutral Mass Spectrometer (INMS), which measures the mass of ions and neutral atoms.
The satellite was to be launched with the bulk of the QB50 constellation to the ISS in 2017, but missed the launch due to a faulty ADCS. It will be launched at a later date.
