Spacecraft data:

Description:

• 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.
• Challenger Sat is a 2U QB50-US01, a QBUS satellite from the University of Colorado.
• Atlantis Sat is a 2U QB50-US02, a QBUS collaboration satellite from the U. of Michigan.
• Columbia Sat is a 2U QB50-US04, part of the QBUS quartet, from Univ. Turabo, Puerto Rico
• Carries the Flux-?-Probe Experiment (FIPEX) of TU Dresden.
