I like the idea of a common vehicle that can be used for exploring an asteroid or as a pressurized rover or for servicing. Then again, the requirements are so very different that it probably doesn't make a heck of a lot of sense. Still looks awesome, though!!!
Nice concepts!I know NASA want to take a SEV on a test-flight to the ISS. I concur!

I concur! hehe. me too!Not sure I'm all for the multiple hatch idea - seems like more things to go wrong, along with added cost & mass. Maybe a secondary hatch for cargo replenishment, along with a utilities connection interface for other consumables.

It has three docking ports of which only two are for the crew(third could be used to dock something that does not need crew access) or give flexability about it's storage). It has suit ports and 1 small object airlock. I would suspect that having an back up docking port would be a good idea in case one does not work. I wonder could it be evoled into a lunar or mars lander?

It looks like they increased the commonality between the two vehicles (planetary and in-space SEV), which is a smart move. But I'm a little disappointed to see the rectangular docking port removed.
Not sure why they changed the windows, looks to now have a more restricted field of view. Maybe the move to flat pieces was done to simplify manufacturing process.
In the new design I can't see the suit port but in may just be behind our point of view
If the image posted on twitter is accurate than this PDF is outdated.
I think the suitport bay is closed, but perhaps it was dropped in favor of the traditional airlock design since they are mainly focused on in space?
Engineers at Johnson Space Center (JSC) are developing an Environmental Control and Life Support System (ECLSS) design for the Space Exploration Vehicle (SEV). The SEV will aid to expand the human exploration envelope for Geostationary Transfer Orbit (GEO), Near Earth Object (NEO), or planetary missions by using pressurized surface exploration vehicles. The SEV, formerly known as the Lunar Electric Rover (LER), will be an evolutionary design starting as a ground test prototype here technologies for various systems will be tested and evolve into a flight vehicle.
Safe human exploration in space missions requires careful management of limited resources such as breathable air and stored electrical energy. Daily activities for astronauts must be carefully planned with respect to such resources, and usage must be monitored as activities proceed to ensure that they can be completed while maintaining safe resource margins. Such planning and monitoring can be complex because they depend on models of resource usage, the activities being planned, and uncertainties. This paper describes a system and the technology behind it - for energy management of the NASA-Johnson Space Center’s Multi-Mission Space Exploration Vehicles (SEV), that provides, in an onboard advisory mode, situational awareness to astronauts and real-time guidance to mission operators.
