The Mars Gravity
Biosatellite, an international student-led program, will provide an artificial
gravity testbed to study mammalian adaptation and development in partial
gravity. The baseline mission profile specifies a launch of fifteen female
mice and utilizes both rotational and non-rotational time-delayed ground
controls. After five weeks in orbit, the animals will return to earth and will
be recovered rapidly after reentry to minimize the effects of reloading.
The Mars Gravity
payload engineering team has been engaged in designing and prototyping
suitable systems for use on board the satellite. Progress has been made in the
design of animal habitat modules, life support systems and telemetry
solutions. Novel approaches have been developed to meet the unique
requirements imposed by a five-week mission duration.
summarize the status of payload engineering design as presented at Preliminary
Design Review. We outline the reasoning behind major design decisions and
detail the challenges encountered in creating an autonomous life-support
system capable of operating for an extended period. We discuss the
modification and augmentation of existing space hardware technology in the
process of arriving at our current payload design, and detail our plan for
testing systems over the coming months to ensure compliance with all
