There are still two part complete Buran Shuttles out there. One in Moscow and one in Germany. And because its name was/is "Buran", it wouldn't have been confused with the NASA "Shuttle". Unless someone looked at it. ;-] The NASA shuttle may be grounded, but as of now, there are still plans to make it fly. NASA has little choice in that. Congress would not allow them to cancel the only US manned space launch system, until a replacement system is available. They had no problem with ending Apollo in 1975, when Columbia's first flight was expected to be four years later... For example. If the CEV turns out to be an unworkable disaster, then NASA would indeed have to use the Shuttle beyond 2010. Once NASA announces that Shuttles no longer will flty, they become museum pieces and are no longer considered functional. They become part of history. At that point, the word "shuttle" becomes more generic and not so closely associated with the OV-10* vehicles operated by NASA, unless you are associated with one of the museums that exhibit one such vehicle. The word "shuttle" was never owned by NASA. The correct term I guess is the "US Space Shuttle". So the Americans will have to lump the idea if they ever call this EU/Russian project the "Kliper Space Shuttle". Klipper is more likely to retain its name when it flies as opposed to being called "shuttle". Kliper is the Russian project name. The term "shuttle" describes the function of a vehicle. I have no idea if they will ever put these two words together. Same for CEV if it is ever built. Soyuz has retained its name over the years. And the US Space Shuttle had no other name. STS, aka Space Transportation System. See Dennis Jenkins' authorative book of the same name. It just so happens that NASA called its OV10* vehicles "Shuttles". That can happen. Many people can also catch the "shuttle" to work. In fact in my town there is a bus "shuttle service" running between the town center and Europe's largest shopping complex. As long as the NASA space Shuttle is scheduled to fly, the word "shuttle" will be closely associated with the NASA Space Shuttle (STS). Only in the USA. And, on BBC, which called the Discovery the " shuttle "... Andre -- " I'm a man... But, I can change... If I have to... I guess. " The Man Prayer, Red Green. |

Ptichka was the most complete other Shuttle, which I believe is now in Gorky Park in Moscow. As I'll be in Russia for a little over a week starting Saturday (6 days in St. Petersburg, 3 or so in Moscow), are there any other interesting space sites to see in the area?

And you'll have to send replacements more frequently, since you'll have no real idea why they keep failing if you can't bring the failed ones back to the ground intact. The next step in space evolution would be to have the tools and documentation to allow the ISS crewmembers to perform the forensic analysys of failed components. (assuming CMGs could be fitted through airlock hatch, or at least a CMG with creative use of an empty MPLM with arm. (vacuum, in MPLM, arm keeps it away from CBM hatch. EVA cremembers put failed CMG in MPLM. close hatch. Arm then berths MPLM to node. They then repressurise MPLM and can then work in the MPLM to dissect the CMG). If CMGs cannot fit through any of the station's hatches, then it is a design issue. For a mars expedition ship, perhaps it should be a requirement that every device have the ability to be brought back in for repair/analysis. The ability to dissect failed components (and possibly repair them) on-board the station would greatly alleviate the lack of the shuttle's ability to return gear to earth. |

This is all just SO encouraging when we're talking about going to the Moon and Mars. "We want to build a moon base, but don't ask us to keep a CMG working or go up 300 miles to Hubble, it's too hard..." Maybe we should just pull the plug on NASA now. No. Au contraire. This is the real science being done in space right now. NASA may talk about watching crystals grow in a test tube as the science, but the real stuff is testing items such as CMGs, Elektron, CDRA, laptops etc and anything else that has failed or given many hiccups and learning why it does this and how to fix it. So while it makes NASA look "incompetant" when you hear about CMG failures, or make russians look stupid with Elektron's colourful history, these are very valuable experiences and both NASA and Russia should be learning a lot from it. The EVA to pick a piece of lint out of the tiles near the nose landing gear door was probably a no brainer for the crew. But to NASA, it was a major "push the boundaries" event, similar to the first EVA with only 2 crewmembers on the station which NASA procedures stated was impossible to do, but which the crew showed was quite possible to get done and thus pushed the boundaries. A lot of the restrictions are ground based due to rules/procedures written a long time ago, and it takes certain events to get NASA to give the OK to do something which in the past was judged too "out there". The fact that NASA now feels confident enough to relax some of those rules is a good sign that NASA is gaining experience and confidence in its ability to do new stuff and push the boundaries in space. There is progress being made due to the failure of devices. |

ATV exists. It's not complete yet, and a year from flying roughly, but it exists. Until it flies, and flies successfully, I don't count it. Period. PR flyers are a dime a dozen. Flown systems are the real thing. ATV is more realistic than HTV, Klipper or CEV. They've already fitted the station with the gear to let its guidance system dock. The first flight ATV has been built. ATV has a lot of conventional technologies: MPLM shell for cargo module. Russian made docking module. Ariane 5 for launcher. But there is also a lot of new stuff (guidance, propulsion for orbiting tug etc). It is already late. And likely to see more delays while they debug the vehicle. And hopefully the modified Arianne 5 won't blow up when it launches ATV. So yes, you can't bet your life on ATV yet. But it is far from being vapourware. HTV on the other hand is a big question mark. ESA has experience with Arianne 5. How much experience does Japan have with launchers ? |
