Features of SEVRanges of Exploration

Presence of SEV on a planetary surface will extend exploration range tomore than 125 miles. Even in the midst of challenging terrain,

emergency shelter and support can be less than an hour awayAstronaut Protection

Rapidly accessible, pressurize and radiation- hard cabin can protect crewmembers for up to 72 hours against solar particle events and otheremergencies

Rapid Ingress/EgressThe suit-port allows the crew to enter and exit their spacesuits without

bringing the suit inside, make internal space comfortable

Intra Vehicular Activity (IVA) Capability

SEV gives crew members the unprecedented flexibility to easily switch the

clothes. Also cabin serve as a rolling science lab for studying samples
