Split as more information found, seems to be an evolution of the old LER optimized for in space operations

Not sure if this belongs in Orion, but evolution of the Space Exploration Vehicle:

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!!!

EDIT: Stick it on an ATHLETE-type rover, and then it can climb up rocky hills. :) I know, I know... Legos...

I wouldn't say that, the biggest difference between an asteroid and the moon is the gravity well, and that is solved with the Mobility Chassis.  Only thing that the SEV would need for an asteroid would be thrusters  but even then not that many if Orion is close by.

Also notice the design has changed to have a clam shell that covers the suitports rather than open like the LER.

Nice concepts!

I know NASA want to take a SEV on a test-flight to the ISS. I concur! :)

hehe. me too!

Not sure I'm all for the multiple hatch port 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.

Nah, not that many hatchs.  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?

Sorry, I should have said docking ports (will amend), but I still think it's one too many.

This diagram doesn't seem to be arranged like either a family tree or a timeline, so its kind of hard to follow.

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.

I've seen the Lunar Electric Rover with a suit port cover as far back as D-Rats 2009.

Looks like they replace it with iLIDS, which is a practical matter with all of the work that has been done on it, especially if you are concentrating on in space work first.

suspect it was changed to use existing engineering work, aka modifying Cupola Window technology for the SEV to save time/development/money.

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?

Indeed that would be true, but we have seen so little of the design even some outdated photos are informative.

I hope not, the suit ports are a really good idea (dust mitigation, lower loss of gas, allows to quickly begin and end EVAs).

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 Centerís Multi-Mission Space Exploration Vehicles (SEV), that provides, in an onboard advisory mode, situational awareness to astronauts and real-time guidance to mission operators.

I like the idea of somewhat common hull for several missions as it could really save a lot of money and speed up development by years.
It's like some of the stuff you see in scifi's like 2001 and Space 1999.

AWESOME!

Mockups are better than just powerpoints! Must mean they're getting serious about this concept. :)

The more awesome exploration spacecraft like this, the better!!!!

oh man, this is amazing, I hadn't seen the MMSEV designs until now.  looks just great.  I can't wait till this thing flies
