NASA To Send SpaceX Resupply Capsule To ISS Despite Technical Problems

Posted by samzenpus on from the show-must-go-on dept.

An anonymous reader writes "Despite a critical backup computer failing on the ISS Friday, an unmanned SpaceX rocket will launch from Cape Canaveral at 4:58 p.m. Monday with more than 2 tons of supplies for the space station. From the article: 'The U.S. National Aeronautics and Space Administration decided to proceed with its resupply mission, despite technical problems with its computer in the International Space Station (ISS), as it needed to deliver necessary supplies.'"

    There's some risk involved but missing the launch window for supplies could be a greater risk (and spoilage time, etc;)

      Yes. The "obstacle" causing the delay was a problem with a backup unit, while the primary is still functioning fine. They had originally scheduled a spacewalk to fix the backup, but presumably, in the event of a failure, they could just "park" the Dragon a convenient orbit to await repairs. So they're better off launching now instead of waiting for the repairs.

      Sounds good to me... I just want to see another Falcon fly... ;-)

      And if I'm not mistaken, this next flight will also be their first attempt to recover the first stage by propulsive landing. Demonstrating such a capability would be a game changer in itself.

      IIRC, they're not trying to land this 1st stage on land, instead they're going for a "soft splashdown" in the ocean. But if they get good "numbers" from this attempt, they will probably try a "dry" landing in the near future.

      I think they also want to try to recover the stage. Normally they break up because of the stress of sub-orbital re-entry or from hitting the water. (The Shuttle SRBs were designed to take the stress of splashdown.) If this works, it would stop and hover just above the water, then cut out the engines and flop over. This one might not be reusable thanks to salt water, but this is only one test on the way to the final goal.

    Well... there are "technical problems." and there are "TECHNICAL PROBLEMS!!!! RUN! RUN FOR YOUR LIFE!"

    please note, the technical problems are on the ISS and have noting to do with any Space X equipment.
