Let's say LM is awarded 10 flights.Jupiter might be expensive, so say it costs $300 million. The containers (which have plenty of volume) may cost only $40 million (or less!) since they're mostly just passive metal. Say LM buys Atlas V flights for $130 million each. That means each mission costs about $200 million each, but should have greater cargo than Dragon or Cygnus.Sounds competitive to me, even if you tag on another $300 million dev cost for Jupiter bringing per mission costs to $230 million....Now suppose you add in another 10 mission, this time launched on a reusable F9 with a 35% discount, giving a per mission cost of just $80 million...

It tends to makes things cheaper, and it enables us to grow far more in the future than we ever could with the old paradigm of building everything new for every mission.

I don't think CRS should be used to prop up the space economies of other countries when the US space economy is in as bad of shape as it's in.The U.S. space economy is in the best shape its ever been in.

Working with companies in other countries lets us get more out of each tax dollar we spend, and makes it easier for U.S. companies to sell to the governments of those other countries in return.What you're proposing is a form of protectionism.

Quote from: Blackstar on 03/13/2015 03:15 amI've read plenty of space enthusiast comments that Bigelow space habitats are just around the corner and will provide plenty of business for SpaceX.So NASA could pick two new entrants in the field, develop new capabilities, and leave SpaceX to fill the sky with their Dragons servicing all those Bigelow space stations that will soon be up there.Right?What Port said.NASA's goal with CRS-2 is to obtain reliable and preferably cost-effective transportation of cargo to the ISS. I really like this concept. (I'd like it even more if it used a cheaper launch vehicle.) I doubt NASA will pick it though. BTW: Bigelow space habitats have been "just around the corner" for a while and probably will be for 5-7 years at least. Lots of work still needs to be done.I would love to be proven wrong.

Since this is a CRS contract, I'm assuming that all vehicle development costs will be paid for by the companies making their various pitches, not by NASA or other government agencies. They'll only pay for the delivery and return services. It's not a COTS equivalent. Is this correct? Cheers
I'm surprised that no one has thought that LM, with Jupiter, is winking to NASA, indirectly suggesting a solution to fund (through CRS2) the development of a basic SM for Orion. A SM with a robotic arm, swappable tanks (its easy to increase the amount of fuel and oxidizer, just enlarge the tanks), and ion propulsion. All of that more or less for free. Yes, I know, the low power engine may be useful only in LEO, but it's a start. We need to keep in mind that the European SM for Orion is only 1, for the first mission. And then? Jupiter may be perfect also because it can be throughly tested in space before using it with a manned Orion.Once funded through CRS2 resupply mission (that NASA has to pay anyhow), Jupiter can also be a low cost base to develop the ARM tug, an Hubble servicing tug and so on.A forward-looking NASA administrator may trade the complexity of this solution with the savings it can give in these future missions.
Try this:1) Jupiter rendezvouses with the new pod and upper stage, grappling the Centaur (NOT the new pod) with its arm, as depicted in the picture.2) Jupiter maneuvers itself so the POA like end effector on the satellite bus ( end of the robot arm sticking out of the top) grabs the new pod 3) the new pod is released, the robot arm flips the stack around and berths the old one to the centaur4) the Jupiter releases the old pod, arm moves away and releases the arm
It being dependent on Atlas V is possibly a problem.
Is the propulsion system (presumably hydrazine monopropellant like MAVEN?) on the reusable bus or the expendable pod?
