Default SpaceX Falcon 9 F3 COTS2+ Updates
by Kyle 12-10-2010, 09:04 PM

Updates on SpaceX's Falcon 9's third flight, 2nd flight of the Dragon spacecraft.



SOURCE OF ARTICLE: http://www.nasaspaceflight.com/2010/...gon-cots-demo/

Quote:
The next Dragon mission, Dragon C2, is currently scheduled for launch on 12 April next year; the fiftieth anniversary of the first manned spaceflight and the thirtieth anniversary of the first Space Shuttle launch. This will also be the next Falcon 9 launch. Dragon C1 is also the fifteenth and final orbital launch of the year to be made by the United States.

Well, SpaceX has been doing well. I'm confident Dragon will be a success, but not so confident they will dock in the next mission.

I feel that Space X is the right agency to go with to get our Human and cargo flights back on track.

The same module is used for both manned and unmanned docking
It's CBM interface permits ISPRs and other large cargo easy transfer
It's 4 man+ capacity is ideal for crew transfer
It's launch system Falcon 9 is performing very well in tests

Lockheed Martin don't even have a tested vehicle. Why NASA awarded them the contract is beyond me!.

Both the NASA COTS management and Elon Musk feel pretty confident about combining COTS 2 and 3 into a single mission.

[SpaceX] hopes to combine the two remaining flight demos slated for later this year; Lindenmoyer said the agency [NASA] is still reviewing that proposal.

The Ares rocket caused the Orion to be redesigned a couple of times (most prominently the switch from a 5.5m base to a 5m base.)

I didnt have much confidence in Space X (oh no another kistler or rotorocket) but they are making good on their efforts.
The thing thats impressing me is they are making everything they use basically the same. Same diameter stages, ie same tooling, same basic engines for both stages. Same pumps, it really is most efficient way, and keeps it simpler. I think 9 engines are a bit much, but musk says they are thinking about going to a bigger engine. And he says next launch will be effort to test stage recovery which is cool. Get the thing out of the ocean, wash it down, check for damaged items and replace them.
go space x

Russia will not permit...

SpaceX not allowed to dock with ISS until safety proven - Roscosmos

20:19 22/04/2011

Russia will not permit the first U.S. commercial spacecraft to dock with the International Space Station (ISS) unless its safety is fully tested, a high-ranking Russian space official said on Friday.

The statement comes in the wake of media reports that the spacecraft's designer, U.S. company SpaceX, requested NASA to authorize the docking in December.

"We will not issue docking permission unless the necessary level of reliability and safety [of the spacecraft] is proven. So far we have no proof that those spacecraft duly comply with the accepted norms of spaceflight safety," said Alexei Krasnov, who heads the manned spaceflight department of Russia's space agency Roscosmos.

He said that to authorize docking, the Russian space agency will need to study data about the demonstration flight due to take place later this year.

"We have received no requests from NASA on the issue," the space official said.

"This plan is realistic, and ultimately commercial spacecraft will be able to dock with the space station," he said. "But all in good time."

SpaceX, a commercial company, signed a contract with NASA to develop both the Falcon-9 carrier rocket and the Dragon vehicle. Last December, SpaceX orbited the Dragon onboard its carrier rocket and demonstrated orbital maneuvering, before the vehicle reentered the atmosphere and was recovered in the Pacific.

According to the SpaceX 2011's launch schedule, two Dragon flights are to take place in 2011. During the first flight, the spacecraft will perform the flyby of the ISS, approaching to within 10 km from the station. During the second mission, it is hoped to dock with the ISS.

I think they are right to play safe. And now we can't count on the Shuttle for heavy repairs / module replacement.

However, I'd be curious to know what are exactly their criterias for an "acceptable level of reliability".

The bad thought about this : maybe Russia will try to keep it's manned space access exclusivity for the longest time possible... Or waiting that other countries sign a big check in exchange of a "russian reliablility certification"... Money, money...

Thinking rationally, it should be interpreted as an objection to allow docking attempt at first approach of Dragon at the ISS. ATV and HTV did rehearsal approaches before coming in for final docking. Probably, the same is expected to be done by Dragon, too.

I wouldn't be totally surprised of that. There's no contra-monopoly law denying them doing so, but in my imagination future good relations and reputation of a good contractor cost more than today's revenue for someone who plans for the future.

My thoughts:

I don't think it actually has anything to do with Russia having concerns with Dragon. I think it has more to do with Russia wanting to be treated as an equal partner. For example: NASA insists on Russia giving them information on all Soyuz & Progress launches. NASA even conduct meetings to discuss whether the ISS is ready to accept the Soyuz/Progress. These meetings always result in a "Go". However, if they ever resulted in a "No-Go", I wonder whether Russia would actually postpone the Soyuz/Progress launch? I doubt it. Russia would likely see it as just another attempt by the Americans to control something that doesn't belong to them.

Now, Russia are merely asking to review Dragon - exactly like the Americans ask to review Soyuzes/Progresses. And there is outrage. Why is it acceptable for the Americans to have a say in Russian spacecraft, but not acceptable for Russia to have a say in American spacecraft? That's not an equal partnership. And that's why I think this move by Russia is merely an attempt to "flex their muscles" and show America that they want to be a partner, not a 2nd thought.

As much as I'd like to say "Screw the Ruskies, dock it anyway", the ISS represents a huge investment to Russia just as it does to the US, and we should give them a say on safety.

I do wonder about the politics, though. Russia is about to become the sole provider of manned spaceflight for basically the entire world, which means they can charge whatever they want for a Soyuz seat. SpaceX is threatening to launch six or seven people for the cost of one Soyuz seat.
