Canadian Robot Could Rescue Hubble

NETHED writes "We have all seen Stories about The Hubble Space Telescope and its current problems. Since then, NASA has okayed the fix of the HST. It seems that America's neighbor to the North has some answers. Dextre to the rescue. The mission would not be decided upon until next summer says Sean O'Keefe. It seems that NASA saw this as a good way to listen to the public for about 1.6 billion dollars." Update: 08/11 15:45 GMT by T : Reader Michael Mol dug up a link with a more technical explanation of Dextre, noting "It looks like Dextre's normally supposed to be attached to something before it performs work."

    I'm quite glad that public outcry over abandoning Hubble has changed NASA's plan for the space telescope.

    It was poor timing on NASA's part, really, because just when the latest and greatest pics from Hubble were gaining mass popularity, they wanted to pull the plug. Maybe O'Keefe isn't the savviest politician?

    The HST is one of the coolest tools we have for exploration. I'm rather glad that it will be serviced, and thanks to our country's hat (Canada) for stepping up.

    The Hubble wasn't designed to be entirely serviceable...that led to problems with previous servicing missions, most notably replacing the old defective mirror.

      Each shuttle launch used to cost between 500 and 1000 million. This one would cost more as to satisfy the CAIB report a second shuttle and team would have to be on the pad, ready to go just in case there was a problem. They would have to train the second crew in rescue and have its support team prepped and ready to go. So really the cost of going to Hubble with a shuttle and with DEXTER is about the same in the end.

      The benefit of DEXTER is that it is out of the loop of the CIAB and the refit of the shuttles. As the shuttle refit is largely being done for IIS, it would probably take some priority over HST. Then you start bumping into the end of life for HST. If the batteries fail you cannot control the telescope and hence cannot dock with it. So really the slight extra cost is outweighed by the benefits.

      Now the question if can the robot really install the COS is a different question (the hardest part of the proposed mission). But thats what the next year of studies are about.

    Besides, we need to keep Hubble going; The Webb telescope is NOT a replacement for Hubble - it looks at different wavelengths; if we could ever get both of them operating at the same time they could be used in a complimentary fashion.

    And it's scheduled to launch in 7 years, which any astronomer knows, doesn't imply that NASA is measuring time in Earth years.

    As a rule of thumb, NASA schedules appear to use Martian years, occasionally using bodies in the Asteroid belt when Mars is feeling uncooperative. For instance, ISS will take 5 years to complete, the Galileo probe will arrive at Jupiter in 1986, and so on.
