NASA Seeks Proposals For Hubble Robotic Servicing

hcg50a writes "SpaceFlight Now has an article about NASA asking for proposals to mount a robotic mission to service the Hubble Space Telescope. Such a Hubble-servicing mission would occur toward the end of calendar year 2007. If you like politics mixed with your spaceflight, you can read NASA Administrator O'Keefe's speech in which the announcement was made."

    The great part of this plan is that it gives NASA a specific goal for implementing robotic repair/servicing. They get to use the project as a testing ground for new technologies, some of which will surely make their way into other future missions. Costs will go down for "routine" orbital missions that can be automated, allowing us to do more in near space and saving the money for other missions demanding astronauts.

They invested their dollars in a very fragile spacecraft combining all the worst elements of a solid-fueled and liquid fueled rocket. Moreover they took on all the limitations of the airplane. 5 operational craft were constructed, two have been lost. The suggestion is that each craft has a lifespan on the order of 25 flights. All failures to date have been catastrophic, with 7 fatalities apiece.

      This is really hard to justify particularly considering that at least Atlantis and Discovery are close to EOL based upon our past experience. Two more disasters to look forward to. It's hard to escape the conclusion that the Shuttle was a flawed design and should not have been built.

      While NASA may fly a Shuttle again, the program will never be back 'on track'. I think this is what O'Keefe keeps telling us. The US might wish to keep the *possibility* of using a Shuttle available for military reasons or as an ISS rescue, the program is fundamentally dead. The Shuttle will be retired when some other manned vehicle is made available in the mid-2010s. Hopefully a non-reusable, proven capsule design.

They had electrical problems, engine problems of various types and other equipment problems. There have been very few flights that have not had at least one failure of one component or piece of equipment. It's the nature of mechanical and electrical systems to fail at some point and that is to be expected, anticipated, and planned for. NASA does this, for the very most part.

Lots of human decision making involved, improvisation and creativity - if they're talking telerobotics (as in telerobotic surgery) then they've got a prayer. But if anyone has in their mind that they're going to line up autonomous robots to give the Hubble a new lease, then they need to go back to the DARPA challenge and remember that Apollo 11 would have been just another crater on the moon with a robot at the helm instead of human pilots who could avert the near disaster. Robots are better at some things - humans are better at some things. Use them both appropriately, drop the prejudices and accept the risks of exploration.

  15. Hey, forgetting something? by Jonsey · · Score: 3, Insightful

    Latency to LEO isn't more than about 300ms (I remember that Sattelite internet access has at least a 250ms latency, and IIRC the sats for that are higher up.

    Regardless, while playing around with that much latency isn't fun, it's also not too hard to beam signals up that far... Why don't we just use a "robot" in the battle-bot sense for this, and have an R/C fixer go up there?

    I mean, it's not nearly as nifty, but it's also pretty fool-proof compared to sending up an AI. Maybe a mix approach would work, like our Mars Rovers, or maybe after the gyros & whatnot are fixed on hubble, we let it go AI on other less-critical repairs?

    Sound logical to anyone else?

      All NASA comms for this misison will go through TDRS. The major delay for TDRS comms isn't the radio waves, it's the processing on each end. Through TDRS, the communications delay is on the order of 2-3 seconds.

      Actually if you read closely O'Keefe specifically says they aren't looking at autonomous approaches (except for the docking). During HST servicing everything is going to be teleoperated. There's no way HST could be serviced autonomously, the technology isn't there yet.

    I don't think so. We haven't done that for a very long time.

    I'm not sure we've ever done that, frankly.

  18. Opportunity to prove it by Anonymous Coward · · Score: 2, Insightful

    This is a very important opportunity to demonstrate robotic servicing. Satellite lifetimes are usually limited by running out of fuel. Many satellites are in geostationary orbit where the shuttle cannot reach them for servicing. Some satellites are launched into the wrong orbits or fail in simple ways. The current approach to these problems is to replace the satellite. Many of them cost hundreds of millions of dollars to replace. A space based satellite servicing craft could refuel, repair, upgrade, and move satellites to different orbits for a lower cost than replacing them. This concept reduces the cost and risk for operating in space - the cost of a new robotic system is recouped in the near future through the lower cost of new satellite development and the longer lifetime of new sats. Why hasn't this been done before? Because no one has demonstrated it. Hubble is the perfect opportunity.

  19. NASA already tried and failed at this by Animats · · Score: 2, Informative
    NASA threw $300 million at the Flight Telerobotic Servicer project in the 1990s. That project had roughtly the same spec this one does - a 4-year project to develop a remotely controlled robot for satellite maintenance.

    Total failure. Not even a ground-based prototype. Lots of studies and papers on components, but no real results. It's so NASA.

    The project manager on that project is still on the NASA payroll. That, too, is so NASA.
