2009-01-2461
The general goal of the mission is part lunar science as well as technology demonstration which are not limited to the Moon. The Rover element of the mission is composed of the rover vehicle service model element, locomotion system and the science payload, with a significant constraint on the overall mass. ...The Moon-NEXT Lunar Rover is the mobile component of a lunar lander mission to provide the best possible in situ science and mobility in the area of the Lunar south pole. ...The lunar thermal environment presents the main challenge to autonomous rover thermal design at the selected landing site. A primary goal of the mission is to operate in the polar region of the Moon, in a territory that may support future a manned base.

2008-01-2021
Europe has embarked on a new programme of space exploration involving the development of rover, lander and probe missions to visit planets, moons and near Earth objects (NEOs) throughout the Solar System. ...Europe has embarked on a new programme of space exploration involving the development of rover, lander and probe missions to visit planets, moons and near Earth objects (NEOs) throughout the Solar System. Rovers and landers will require testing under simulated planetary, and NEO conditions to ensure their ability to land on and traverse the alien surfaces. ...ESA has begun work on a building project that will provide an enclosed and controlled environment for testing rover and lander functions such as landing, mobility, navigation and soil sampling. The facility will first support the European ExoMars mission due for launch in 2013.

Access Systems for Partial Gravity Exploration & Rescue: Results from Prototype Testing in an Analog Environment

2007-07-09
2007-01-3033
The rescue system was utilized effectively to extract an injured astronaut up a slope of15-25° and into a surface mobility rover for transport to a simulated habitat for advanced medical care. Further research is recommended to evaluate the effects of reduced gravity and to develop synergies with other surface systems for carrying out the contingency procedures.

2009-01-2569
There is some urgency in creating this concept because NASA has begun building and testing development hardware for the lunar surface, including rovers, habitats and cargo off-loading equipment. Just as with microgravity operations, a lunar EVA work envelope is needed to guide designers in the formative stages of the program with the objective of avoiding difficult and costly rework.

Entry type is also affected by the vehicle and habitat interfaces such as air locks, hatches, and manned rovers. One concept for planetary exploration is to have an unpressurized vestibule attached to the habitat and have the spacesuit attached to the habitat wall acting as an air lock.
