NASA NTRS1995

Assembly Platform For Use In Outer Space

Report describes conceptual platform or framework for use in assembling other structures and spacecraft in outer space. Consists of three fixed structural beams comprising central beam and two cross beams. Robotic manipulators spaced apart on platform to provide telerobotic operation of platform by either space-station or ground crews. Platform and attached vehicles function synergistically to achieve maximum performance for intended purposes.

On-orbit assembly of Mars transfer vehicles

Developmental efforts conducted under NASA-Marshall aegis toward on-orbit assembly for manned Mars mission transfer vehicles (MTV) are presented. The MTV types considered encompass those with cryogenic/aerobraking propulsion, all-cryogenic propulsion, nuclear-thermal propulsion (NTP), nuclear-electric propulsion (NEP), and solar-electric propulsion (SEP). Attention is given to NTP, NEP, and SEP MTVs, in light of the requirements posed by the assembly environment and assembly platform designs. Much important design-related information is being derived from the Long Duration Exposure Facility.
