So this is how things are shaping up (assuming commercial crew goes forward):Orion Block 0 CRV: Crew Rescue Vehicle, launched unmanned on EELVDragon: Crew and Cargo, launched on Falcon 9Boeing Capsule: Crew (cargo?), launched on EELVDreamchaser: Crew, launched on EELV Cygnus: Cargo and potential crew, launched on Taurus IIThe good thing is, if all 5 of these spacecraft get developed for the ISS, that is 5 spacecraft that could potentially be evolved into a BEO spacecraft. Some of the companies may be content with the LEP operations and may not even try for the BEO contract. I know there is a lot of doom and gloom on here right now...just trying to look for a brighter side to things. All things said though, I know a lot of people are going to blame Obama and FY2011 for this. However, Orion was dead right from the start, as Ares I continually dragged it down with it. I think most would agree that if we had just launched it on an EELV, we would be launch, at the very least, an Orion Block 0 by this time. What was done to Orion and those working on it over the last few years was not fair. However, they did amazing work considering what was thrown at them.

I dunno. Looks like too many providers for a small market. I would expect 50% to fail to land contracts lucrative enough to keep building spacecraft.Quote from: gladiator1332 on 06/06/2010 11:29 pmSo this is how things are shaping up (assuming commercial crew goes forward):Orion Block 0 CRV: Crew Rescue Vehicle, launched unmanned on EELVDragon: Crew and Cargo, launched on Falcon 9Boeing Capsule: Crew (cargo?), launched on EELVDreamchaser: Crew, launched on EELV Cygnus: Cargo and potential crew, launched on Taurus IIThe good thing is, if all 5 of these spacecraft get developed for the ISS, that is 5 spacecraft that could potentially be evolved into a BEO spacecraft.

As for whether you can always upgrade a LEO capsule, I don't know enough to know if that is true

There isn't. If commercial was truly commercial they would do it on their own dime. I recongnize the advantage of government helping out, but at the moment there isn't enough 'out there' to warrant have that many players at this time. So NASA's point of 'down-selecting' to just two commercial providers makes sense. But without a solid foundation at the moment (help for ISS to eliminate the gap), we're on a slippery slope until they are ready.But this is about Orion, and it's really ticking me off.
In terms of LEO, Orion wouldn't add anything of note beyond the capabilities of Dragon. Further, given that autonomous rendezvous has been cut, Orion couldn't really do the ISS cargo mission.The case for Orion in LEO is pretty thin. As I've said before, Orion was designed for the LOR mission profile, and if we're not sending humans to LLO or EML, it's not really the right tool for whatever job it is we're trying to do.I think the idea that we could save Orion after giving up on the lunar landing is just as misguided as the idea that we could save Shuttle after finishing ISS assembly.Right now, our objectives are ISS logistics and flexible path. Dragon is the best tool for the first job, and with some upgrades, it's a pretty good choice for flexible path as well (since a mission module is essential).
And I agree...5 providers for access to the station is more than necessary.
Maybe this is offtopic, but I don't get why Dreamchaser is brought up over and over. It is a paper project! Who exactly is backing it?? It's name may be more apt than what most realize.

It's name may be more apt than what most realize.Sierra Nevada is the company putting forward the concept. It is a viable option for a crew taxi. NASA seems to agree, as Sierra Nevada received $20 million of the $50 million given out in February for CCDev. Given the right time and money, anything can transform from "paper" to reality. I think the events of this week proved that.

For the lunar landing objective, NASA should have left the launch vehicles to the private sector (e.g. ULA) and focused more on the lander.For flexible path, NASA should focus more on the mission module and leave the rest to the private sector. I'm sure that between ULA and SpaceX, the private sector can deliver the launch vehicles and crew capsule necessary to utilize NASA's flexible path mission module.For example: An ISS-derived mission module and a Centaur could launch on Atlas V. Then a suitably-modified Dragon Crew launches on Falcon 9 and rendezvous/docks with the mission module Centaur stack in LEO for the Earth-departure burn.The important part is the mission module. The capsule is just to launch the crew to LEO and then reentry at the end of the mission.NASA need to get its priorities straight with regard to where it should spend its resources on micromanagement and where it should defer to the private sector.

I think when the VSE was first announced, NASA understood this. The original idea was a simple capsule was going to be launched on existing EELVs, and NASA instead was going to concentrate on the lander and other things needed to return to the Moon. I believe we were going to have a flyoff of the CEV in 2008, and then actual flights to the ISS were going to be in 2010. Then ESAS happened and the rest is history.
Our second goal is to develop and test a new spacecraft, the crew exploration vehicle, by 2008, and to conduct the first manned mission no later than 2014.
...you need a HUGE LAS system which weights a lot....
What I was trying to say, in that tersely worded, now deleted post, was something along these lines:We are now getting ready to cancel a program. Like it or hate it, a lot of good valuable work was done on Orion. Now we are getting ready, if past is prologue, to flush that data down the memory hole. Perhaps forty years from now, Jim will be able to post a dog-eared scan of a "classified" Orion datasheet. So I ask, if the program is indeed canceled by Congress, why not, within ITAR limitations, release the entire package to the American taxpayer? Sooner, rather than later. Maybe there's an entrepreneur who thinks he could build a similar capsule for less?Thanks, Andy. Sometimes in my deep frustration, I might possibly maybe get ever so slightly sarcastic....Quote from: trout007 on 06/06/2010 01:50 pm...you need a HUGE LAS system which weights a lot....I thought the LAS was one of the systems that was pretty well worked out by now. Please don't tell me that the pad abort tests did not lift the proper mass?The problem with Creative Destruction is that it seems that the pols delete the first word for the most part.
