SpaceX?s CRS-3 Dragon recruited for ISS spacesuit relay
SpaceX?s CRS-3 Dragon recruited for ISS spacesuit relay
http://www.nasaspaceflight.com/2013/...gon-spacesuit- relay/ From above: SpaceX?s next Dragon mission to the International Space Station (ISS) will involve the delivery of a replacement Extravehicular Mobility Unit (EMU), allowing for the return of a faulty suit on the same vehicle when it returns to Earth. Notably, the returning suit won't be Luca Parmitano?s EMU, after its water leak issues were resolved via successful troubleshooting efforts. Trusting Dragon with an EMU seems like a step down the path of actually trusting it with expensive, somewhat hard to replace, cargo.

Trusting Dragon with an EMU seems like a step down the path of actually trusting it with expensive, somewhat hard to replace, cargo. Probably, but can anything else carry-up an EMU? It sounds like they need a replacement on the station, and of course the station doesn't have unlimited storage space, which means the faulty one has to go one way or the other... Given SpaceX’s next Dragon mission to the ISS – CRS-3 (SpX-3) - was already on standby to bring EMU 3011 back to Earth, the plan is still on to utilize a specially made rack on the spacecraft, allowing for EMU hardware to be launched and returned to and from the ISS. The realigned plan – per L2 information – is to launch a replacement suit, known as EMU 3003, to the ISS on the Dragon, before returning EMU 3015 – which also has a faulty sublimator – to Earth via Dragon’s splashdown homecoming in the Pacific Ocean. rick jones -- web2.0 n, the dot.com reunion tour... these opinions are mine, all mine; HP might not want them anyway... feel free to post, OR email to rick.jones2 in hp.com but NOT BOTH... |

Yes, the Russian Progress, the European ATV, and the Japanese HTV could all carry an EMU up to ISS. If I presume the "special rack" had a version for those vehicles made yes?

I found it interesting that they're trusting Dragon to launch EMU 3003. I wonder how much the Russians would want for a Progress version of the special rack? The fifth and final ESA ATV mission is probably already fully booked? http://en.wikipedia.org/wiki/Automated_Transfer_Vehicle There might have been better luck getting a special rack into one of the upcoming HTVs? http://en.wikipedia.org/wiki/H-II_Transfer_Vehicle So I'm not really all that sure that there was/is an uphill option for an EMU besides Dragon. rick -- Don't anthropomorphize computers.

Yes, there are certain logistics issues which would need to be solved in order to launch an EMU on any cargo vessel. But, there is nothing fundamental which would prevent it from happening. I know Progress has been used in the past to deliver EMU parts to ISS, but I'm not certain it ever delivered an entire EMU. I tried a few quick web searches looking for any evidence that this has ever happened and did not find an answer. So far, nothing "pops up" which would be a document detailing the history of EMU hardware used on ISS. But these two gems popped up. I've already read "Walking to Olympus: An EVA Chronology", but it unfortunately ends with shuttle/Mir. But for those who have not read it yet, it's a good read with lots of details. Walking to Olympus: An EVA Chronology http://spaceflight.nasa.gov/spacenew...fs/EVACron.pdf The other document I found I had not seen before. It is a spreadsheet of space shuttle EVA's. It includes details like which EMU part numbers were used on which space shuttle EVA's. Unfortunately, I could find nothing similar for ISS. EMU numbers used for shuttle EVA's https://www.dropbox.com/s/6q0dg875at...Activities.pdf Jeff -- "the perennial claim that hypersonic airbreathing propulsion would magically make space launch cheaper is nonsense -- LOX is much cheaper than advanced airbreathing engines, and so are the tanks to put it in and the extra thrust to carry it." - Henry Spencer |
