Altair Pathfinder [Millenium Space]
ALTAIR Pathfinder or ALTAIR 1 is a 1×6U CubeSat technology demonstration mission by Millennium Space Systems.
The satellite establishes flight heritage for the majority of Millennium Space Systems' planned ALTAIR Core product line spacecraft design and for payload support technologies. The key ALTAIR core hardware designs are demonstrated and flown in their objective design configurations to retire technical risks, increase Technology Readiness Levels (TRLs) and gain flight heritage for active Department of Defense (DoD) and NASA space programs.
The ALTAIR Pathfinder spacecraft consists of subsystems which incorporate new technologies in direct support of needed capabilities. New elements for space usage in each subsystem are described. The Guidance, Navigation, and Control subsystem includes inertial reference units, star trackers, and conformal torque coils. The Command and Data Handling subsystem utilizes a new flight processor and level zero (no software) control. The Electrical Power Subsystem includes deployable solar arrays. The Structures subsystem uses an additively manufactured structure. The Thermal Control subsystem includes advanced passive thermal management technology. The RF Payload subsystem utilizes high performance front-end and on board processing.
The objectives of the mission are:
Millennium Space Systems has signed a contract with NanoRacks LLC to launch the satellite into Low Earth Orbit (LEO) via the International Space Station (ISS). The spacecraft was carried to the station in 2017 via the Cygnus CRS-7 cargo flight, from where the satellite was deployed on 17 May 2017.
