Docking Hatch:Allows crew members to move from the rover to a habitat, an ascent module or another rover.

The Space Exploration Vehicle Characteristics (Surface Concept)

Suitports:Allow suit donning and vehicle egress in less than 10 minutes with minimal gas loss.

Suit Portable Life Support System-based Environmental Control Life Support System:Reduces mass, cost, volume and complexity.

Ice-shielded Lock / Fusible Heat Sink:Lock surrounded by 2.5 cm of frozen water provides radiation protection. Same ice is used as a fusible heat sink, rejecting heat energyby melting ice instead ofevaporating water to vacuum.

Pressurized Rover:Low-mass, low-volume design makes it possible to have two vehicles on a planetary lunar surface, greatly extending the range of safe exploration.

Work Package Interface:Allows attachment of modular work packages (e.g. winch, cable, backhoe or crane).

Chariot Style Aft Driving Station:Enables crew to drive rover while conducting moonwalks.

Modular Design:Pressurized Rover and chassis may be delivered on separate landers or pre-integrated on one lander.

Pivoting Wheels:Enables crab-style driving for docking and maneuvering on steep terrain.

The Space Exploration Vehicle: NASA plans to conduct human space exploration missions to a variety of destinations. To maximize the number of destinations NASA explores, space exploration systems must be flexible, and NASA must minimize the number of systems developed. One system concept NASA is analyzing is the SEV. The SEV would use the same cabin for in-space missions (i.e., satellite servicing, telescope assembly and exploration of near-Earth asteroids) as well as surface exploration on planetary bodies (i.e., the moon and Mars). On planetary surfaces, astronauts will need surface mobility to explore multiple sites across the lunar and Martian surfaces. The SEV surface concept has the small, pressurized cabin mounted on a wheeled chassis that would enable a mobile form of exploration. These two components could be delivered to the planetary surface together, or as separate elements. The SEV can provide the astronauts’ main mode of transportation, and – unlike the unpressurized Apollo lunar rover – also allow them to go on long excursions without the restrictions imposed by spacesuits. The pressurized cabin has a suitport that allows the crew to get into their spacesuits and out of the vehicle faster than before, enabling multiple, short spacewalks as an alternative to one long spacewalk. The surface exploration version of the SEV also features pivoting wheels that enable “crab style” sideways movement, which helps the vehicle maneuver over difficult terrain. Its tiltable cockpit provides the drivers the best possible view of the terrain ahead. Astronauts can drive the mobility chassis, called Chariot, without the pressurized cabin by riding in rotating turrets while wearing spacesuits. Additionally, Chariot can be used to carry cargo. The modular design allows various tools – winches, cable reels, backhoes, cranes and bulldozer blades – to be attached for special missions. It could even pick up and reposition solarpowered charging stations, communication relays and scientifi c packages. The in-space version of the SEV would have the pressurized cabin on a flying platform and allow astronauts to live inside for up to 14 days. It would provide robotic manipulators to grasp objects for observation, and allow astronauts easy access to space via the suitports, to maximize their productivity performing spacewalks outside of the cabin.
