“…Combining EVA simulation experiences from Desert-RATS and HMP, a reasonable estimate of the total time overhead for each EVA using suit-ports, from donningundock (egress) to redock-doffing (ingress), is 20 minutes (e.g., Hodgson et al 2011). Table 1 compares total times required for sample collection in EVA and IVA modes, the latter via the use of a robotic arm system.…”

“…EVAs from pressurized vehicles will be rendered relatively easy using a suit port approach, but they will always remain associated with substantial added risk and cost. An EVA subjects astronauts to higher radiation exposure than IVA, and incurs added cost in mission operations planning and support, crew rest, life support supplies, and suit wear and tear, particularly in dusty environments (e.g., Gaier et al 2009, Hodgson et al 2011. Reducing the frequency of EVAs will also help address Planetary Protection requirements (Schuerger and Lee 2010).…”

During the 2011 summer field campaign of the NASA Haughton-Mars Project at the Haughton impact crater site on Devon Island in the high Arctic, field tests were conducted of the use of a robotic arm system integrated to Humvees serving as analog pressurized vehicles for the human exploration of near-Earth asteroids, the Moon, and Mars. The goal of these field tests was to begin assessing how field geology, including sample acquisition, might in some cases be conducted effectively from the confines of a pressurized vehicle (in intravehicular or IVA mode) without the crew having to always go out on EVA. Preliminary findings suggest that, particularly at sites where rocks and soils available for sampling occur mostly as loose rubble or "float" (as with planetary regoliths), the use of a robotic arm can allow efficient collection and characterization of high quality samples. An important implication of the finding for future space exploration architecture development, if confirmed through further field tests, is that the number and frequency of EVAs needed for sample acquisition during planetary vehicular traverses might be reduced from current assumptions. Wear and tear on EVA suit and suit-port systems, mission operations complexity, crew exposure to space radiation, and planetary protection concerns, might all be significantly reduced if robotic-arm assisted sample acquisition in IVA mode became available as an effective option for science operations.
