“…Of necessity, in-space laboratories depart from the leading trend in contemporary terrestrial laboratory design practice: "open plan" configurations. 5 The harsh economics of space architecture force contained-module, closed-plan laboratories until extensive in situ construction can be achieved. This means the ISS precedent and other volumeconstrained mobile laboratories are appropriate starting points for adaptation based on planet-surface conditions and the expanded laboratory functional programs described above.…”

The paper analyzes internal outfitting architectures for space exploration laboratory modules. ISS laboratory architecture is examined as a baseline for comparison; applicable insights are derived. Laboratory functional programs are defined for seven planet-surface knowledge domains. Necessary and value-added departures from the ISS architecture standard are defined, and three sectional interior architecture options are assessed for practicality and potential performance. Contemporary guidelines for terrestrial analytical laboratory design are found to be applicable to the in-space functional program. Densepacked racks of system equipment, and high module volume packing ratios, should not be assumed as the default solution for exploration laboratories whose primary activities include un-scriptable investigations and experimentation on the system equipment itself.

“…Two of the surveyed rover concepts included a sample airlock: Griffin (1990) andESA (2000). In combination with an astrobiology "glovebox" research chamber (Cohen, 2000), it holds the key to examining scientific samples inside the pressurized rover while an EVA team of two or more crew members is exploring the terrain on foot outside the rover. The crewmembers collect rocks, soil, and other materials, and place it in a protective containment.…”

“…Instead, it becomes necessary only to pump down or bleed off a very small interstitial volume between the space suit backpack and the "airlockless" inner hatch. The precedents for this strategy include the "Suitport" idea, the NASA-Ames Hazmat vehicle shown in FIGURE 5, and the HamiltonSundstrand "Ready to Wear" Marssuit (Hodgeson & Guyer, 1998, 2000.…”

“…The sample airlock consists of a (usually) cylindrical shell that spans two working environments: the exterior ambient environment of the moon or planet and the working environment inside a research chamber glovebox (Cohen, 1999(Cohen, & 2000. The main mechanical parts are the inner and outer hatches, that require a high degree of reliability to ensure proper opening, closing, latching and sealing.…”

The ability for crewmembers to explore the surface of the Moon or Mars effectively on foot remains a significant test of any exploration design.The availability of a pressurized rover would substantially increase the range of exploration by space suited crewmembers. The design of the airlock systems or functions will facilitate crewmembers in accomplishing these efforts. The pressurized rover for planetary exploration incorporates three types of airlocks or pressure ports: the EVA airlock, the sample airlock and the habitat docking port. This paper conducts a survey of selected precedents in pressurized rover design and then analyzes the key issues for airlock design.
