500 day HAB/MPLM with CPS
Deep Space Habitat (DSH) is a 2012 proposed
NASA conceptual design to support a crew of 4 for exploration beyond
Low Earth Orbit. Initial concept missions include 60 day and 500 day mission configurations, composed of
International Space Station-derived hardware, the
Orion crew capsule and various support craft.
[1] The Habitat would be equipped with at least one
International Docking System Standard (IDSS).
Developing a Deep Space Habitat will allow a crew to live and work
safely in space for up to a year on missions to explore cis-lunar space
and some near-Earth asteroids. It would also provide experience needed
for designing longer-duration habitats that would be needed for
exploring Mars and more distant asteroids.
Configurations
ISS derived Deep Space Habitat HAB/MPLM
ISS derived Deep Space Habitat MPLM/Node1
HAB/MPLM
- 60 Day Mission - The basic 60 day mission variant would consist of a Cryogenic Propulsion Stage (CPS), ISS Destiny-derived
lab module, and an airlock/tunnel. In addition, a mission-specific
support craft, such as the FlexCraft or the Multi-Mission Space
Exploration Vehicle(MMSEV) would be docked to the airlock/tunnel. The
Destiny-derived lab houses both the crew quarters and the ECLSS components.[citation needed]
- 500 Day Mission - The 500 Day mission variant would consist of the same 60 day crew habitat and crew size. Mass increases would result from the addition of a Multi-Purpose Logistics Module (MPLM) to provide additional supply storage for the extended mission duration.[1] It would be 56 feet long, with a diameter of 16 feet, not including the CPS.[citation needed]
MPLM/Node 1
- 60 Day Mission - The basic vehicle elements for this configuration would include a CPS, a MPLM, Utility tunnel/airlock, Node 4 Structural Test Article.
The Node element would allow for the attachment of more than one
FlexCraft or Space Exploration Vehicle (MMSEV). The Habitat would be
crew serviceable at the front of the Node element opposite the tunnel.[citation needed]
Support Craft
- Orion
- NASA designed and currently under construction Deep space manned
capsule. Capable of carrying 4 crew, and able to withstand re-entry
speeds from lunar or martian trajectories. Orion will be used mainly for
crew rotation.
- MMSEV
- NASA designed servicing craft. Capable of supporting 2 crew and
having externally attached EVA suits. It is also capable of free flight
for 2 weeks. The Vehicle has its own lavatory.
- DSH FlexCraft - a single crew vehicle, attached to the DSH similar to a visiting craft to the International Space Station.
Propulsion options
Propulsion options studied included:
[citation needed]
- Cryogenic Propulsion Stage - Traditional high-thrust propulsive stage likely using liquid hydrogen/liquid oxygen-fueled engines.
