Video for Lockheed Martin Jupiter spacecraft

Published on Mar 12, 2015

This video explains Lockheed Martin’s safe, reliable, and affordable solution for NASA’s Commercial Resupply Services 2 program. This solution will deliver and dispose of a large quantity of International Space Station (ISS) cargo. In addition to ISS servicing, the solution proposed by Lockheed Martin develops technologies that are needed to support future human-rated deep space missions.

Sounds like another look at the Orbital Maneuvering Vehicle (Space Tug) concept. It seems to me that you'd need a fairly high tempo of traffic for this to make sense.

I think that they will have a hard time selling this for CRS-2, because NASA seems to be looking for the cheapest option. However, LM may be playing the long game here, because this puts them in place to pitch a vehicle that can be used for beyond low Earth orbit missions.

A lot depends on the details of their CRS-2 bid. The initial mission to put the spacecraft in orbit will have a cost premium, and it will take money to "run" it in orbit through its life. But in theory the ExoLiner missions should be fairly cheap, and once the spacecraft is up there it becomes available for other reasons. If Lockheed were SpaceX, they would probably launch the Jupiter on their own dime and then just make their money back on the ExoLiner flights and other missions. But I don't think Lockheed's corporate culture will permit such a move, unless someone else pays for Jupiter it won't happen.
 
NASA has informed Boeing that it is out of the running for a $3.5 billion competition to send cargo
to the International Space Station, a company spokeswoman said Thursday.
Boeing has received a NASA contract to send astronauts to the ISS aboard its CST-100 Starliner
capsule beginning as early as 2017, but its bid to get US space agency funds for a cargo version in
the coming years was dismissed.
"We received some information as part of the letter we received from NASA this morning but until we
get the debrief we can't say much," Boeing spokeswoman Kelly Kaplan told AFP.
While some analysts had expected an announcement this week, NASA's website showed
that the space agency has pushed back its timeline to announce the award to no later than January 30.
SpaceX and Orbital each got a share of NASA's first round of $3.6 billion in commercial cargo
contracts to supply the ISS, are still in the running for the second round of funding under a program
called Commercial Resupply Services 2 (CRS2).
Sierra Nevada Corporation is also reportedly still in the running.
According to the Florida Today newspaper, which first broke the news on Thursday of Boeing's loss,
Sierra Nevada Corp. said "NASA is continuing CRS2 discussions with the company as one of the
offerors in the competitive range."
The capsule that Boeing had proposed to send to the ISS was a variation on its CST-100 Starliner,
Kaplan said. "It would have been the same spacecraft but just a cargo variant," she said.

That isn't commercial resupply. That is commercial crew. Different contracts and vehicles.

My bad. Suffered a brain fart, pardon my French.
 
Via Spacedaily, a joint press release from ULA & Boeing: United Launch Alliance and the Boeing Company Unveil the Atlas V Configuration for the CST-100 Starliner Crew Capsule

428617

This new configuration incorporates an aeroskirt aft of the spacecraft, extending the Starliner Service Module cylindrical surface to improve the aerodynamic characteristics of the integrated launch configuration and bring loads margins back to acceptable flight levels.

"Through incredible coordination and continued innovative thinking, the collective team of NASA, Boeing and United Launch Alliance completed three wind tunnel tests in six months to investigate the aerodynamic stability of various configurations and to anchor our analytical predictions. Based on that information, we updated the configuration for the Atlas V Starliner integrated vehicle stack," said Gary Wentz, ULA vice president of Human and Commercial Services. "This configuration is unique because it combines the Atlas V launch vehicle without a payload fairing with Boeing's Starliner capsule, resulting in different aerodynamic interactions."

The aeroskirt is a metallic orthogrid structure designed to be jettisoned for improved performance. In the unlikely event that an emergency occurs during boost phase of flight, the aeroskirt has venting provisions to control over-pressurization if the Starliner's abort engines are fired. Fabrication of the aeroskirt is scheduled to begin this month at ULA's factory in Decatur, Alabama, following completion of a Production Readiness Review.

"Our testing indicates the solution we chose will sufficiently smooth the air flow around the vehicle during ascent, ensuring crew safety and mission success," said John Mulholland, vice president and program manager of Boeing's Commercial Crew Program.

The ULA team completed the aeroskirt Preliminary Design Review earlier this month. The Atlas V with Starliner has a planned uncrewed flight test in 2018 with operational missions to follow.
