  • Wasn't the shuttle scheduled to do one-last service call on Hubble? This is despite NASA's foot-dragging
    and originally deciding NOT to service it and just retire it.

    Gee, if it's fried, then they can't do a normal maintenance and can save $100M on a launch....
    And if it's just been told to "roll over and play dead"......

      The Hubble is getting old.
      I'm pretty sure they were going to stop servicing it.
      The question is: Will they come up with a replacement or try to fix the Hubble again?
      And would be cost effective to repair it again or has it's time finally come?

        I thought they already had a service launch scheduled for sometime soon...

        From http://hubble.nasa.gov/index.php [nasa.gov]: "Hubble to be Serviced Again Administrator Michael Griffin's decision on October 31, 2006 to fly servicing mission SM4 in mid- to late-2008 will bring unique capabilities to Hubble in the form of two new science instruments, Cosmic Origins Spectrograph and Wide Field Camera 3. In addition, new gyros and batteries will extend Hubble's life through 2013."

        Of course by then it may be too late..

      The Advanced Camera for Surveys wasn't installed until the third servicing mission in 2002. It's been problematic since then. If it can be installed on a spacewalk, it can be replaced on a spacewalk.

      Also, the Hubble servicing mission has been approved. Barring some act of God or Congress, Atlantis will conduct this mission on STS-125 in May of 2008. The ACS was not on the itinerary for service, but it might still be possible to add it to the agenda or push back the mission date if need be. On the other hand, it might be possible to work around whatever problem caused the latest shutdown, the third according to Wikipedia.

      I should point out the foot dragging was largely spurred on by calls for the retirement of the shuttle as soon as possible (even immediately) and some general hysteria following the Columbia incident (as opposed to the rational re-examination that also took place). There is also the issue of the cost, which is in the range of hundreds of millions and had not been provided for, and a difference of philosophy between O'Keefe (administrator until 2005) and Griffin (current admin). Mission development is fully provided for in 2007, and should be in the 2008 budget, too.

      If Hubble was going to roll over and play dead, it should've done so back in mid-2005, before more money had been spent on the servicing mission.

    Since they have already said that repair missions to the hubble scope are off the agenda, sooner or later its going to die. There are replacements on the way anyhow.

    Personally I think they should boost it into higher orbit so it stays safe for future space archeologists. The same bods who will eventually be interested in retreiving the Viking missions, and who knows, if we get fast enough ships, the voyagers.

      The parent is not informative, it is wrong, or at least out of date.

      The Space Shuttle will be retired upon completion of the ISS. NASA will be taking steps over the coming years which would prevent almost any extension of the currently planned flight schedule, like reconfiguring launch pads to support the future vehicles, retiring shuttle craft as they complete their scheduled missions, caniballizing said vehicles for parts, and refraining from ordering parts like external tanks and solid rocket boosters which would be required to extend the schedule by even one flight.

      The shuttle will cease operations regardless of the status of replacement vehicles. Although many planned technology programs intended to help replace the shuttle with a more reliable and cost effective system were cancelled over the years, NASA is currently pursuing a manned vehicle program, Orion [wikipedia.org] which has not been cancelled.
      • by rbanffy (584143)
        I have some faith.

        NASA has big cargo capacity in the ARES V heavy-lifter and a much smaller manned craft in the ARES I. There is not much for returning orbiting cargo, something the shuttle could do, but I suspect it is cheaper to strap a heat shield and parachutes on anything that need to go down in one piece.

        ESA was also planning a cargo vehicle to replace the Progress ships.

        Using the shuttle for both types of mission, crew and cargo, is terribly ineffective. It should have stopped long ago.

First there is the funding issue, then there is the parts issue...they don't make STS parts anymore! Specifically, the STS main engines can no longer be rebuilt and/or upgraded, the program to do that was cancelled several years ago. Rocket Engines don't last forever. The engines must be rebuilt every 5 or so launches or they risk losing 1 or more of them during a launch. If any systems break

      The smell that is normally associated with shorts is ozone, which would not be produced without some oxygen around.
      • The smell of ozone is more associated with high voltage corona and arcing than with a short circuit.

        Given enough available energy, a short circuit will heat wires enough to melt/burn insulation, or even vaporize the metal conductor itself. The typical smell associated with letting the magic smoke out of something isn't ozone, but burning plastic and phenolic insulation.

Yes, I realize that I may be oversimplying this procedure, but if it's not feasible to service it in the near future, is there something wrong with tucking it away in a safe orbit until it would become feasible...or clea

      Single servicing mission in 2008: $900 million [space.com]

      I like Hubble a lot, but other missions [caltech.edu] which don't require (or allow) Shuttle service and cost on the order of $0.3-0.8 billion seem to me far more cost effective. The mirror is a tiny fraction of the cumulative operations costs.

      Optics are the valuable part, but fuel is the trickiest part. If they can refuel HST, then in theory they could keep it up there forever. The problem is, as another reply mentioned, cost effectiveness--we have optical telescope arrays on the ground now that give us better images than Hubble's main camera.

    FTA:

    The ACS anomaly comes just two months before the instrument's projected five-year warranty expired, Hubble managers said. Spacewalking astronauts installed the camera on March 7, 2002 during NASA's STS-109 mission aboard the Columbia orbiter.

    In all seriousness, though, it's worth noting that this camera is comparatively new (installed 12 years after launch) and that it's failed more or less on schedule. Too bad NASA doesn't plan on sending a mission until next year. Also worth noting is that it's not the only instrument on the telescope... though it is the one that takes the purty pictures that garner mainstream attention.

      Neither can Hubble. The Hubble Deep Field was pieced together from 10 nights of images. The newer Hubble Ultra Deep Field, from 11 nights.

      Pretty much any half-decent-looking astronomical image you see is a combination of multiple exposures. I'm one of the operators of the 2.2-meter (that's slightly smaller than Hubble) telescope on Mauna Kea, and have been teaching myself the process of getting and combining images in different filters/wavelengths. For example, I made this shot of M76 [hawaii.edu] from about a dozen exposures. (Using, incidentally, the same instrument that was used to discover the Kuiper Belt back in 1992.)

      Just a data point.

    For other astronomers who might get their news from slashdot before other sources:

    HST entered inertial safe mode on Saturday January 27. Preliminary indications are that this event was associated with an ACS anomaly. GSFC and STScI engineers and scientists are still investigating the situation, but it appears unlikely that ACS CCD observations (both WFC and HRC) will be available in Cycle 16. Current indications are that ACS/SBC can be restored using operational workarounds, so observers should assume that the ACS/SBC configuration will be available in Cycle 16.

    The formal Cycle 16 deadline was 8 pm EST on Friday Jan 26. We received a total of 747 proposals, including 498 to use ACS/WFC or ACS/HRC. The latter proposals are unlikely to be viable. In order to ensure that we accommodate the science areas covered by those programs, we are extending the HST Cycle 16 deadline.

    We encourage Principal Investigators who submitted proposals for ACS observations with either WFC or HRC to consider whether those observations could be made with WFPC2.
    The new deadline is Friday 9th Feb, extended from 26th Jan.

    Jargon alert for non specialists: ACS = Advanced Camera for Surveys; WFC = Wide Field Camera; HRC = High Resolution Camera; SBC = Solar Blind Channel; CCD = charge coupled device; WFPC2 = Wide Field and Planetary Camera 2 (an older instrument); STScI = Space Telescope Science Institute; and GSFC = Goddard Space Flight Center.

    I work at STScI and it sounds like they're going to be able to switch ACS back to the side 1 power supply. Unfortunately, it means that the WFC which is the most used won't be working. A failure of the side 1 supply to WFC is why they had to switch to side 2 this summer.

    The good news is that WFPC2 is still working even if it doesn't have the imaging area or sensitivity of ACS. The telescope allocation committee just re-opened applications for next cycle so lots of people are just going to switch their proposals from using ACS to using WFPC2 (myself included). As a side note: anyone can apply for telescope time since its run with taxpayer money. Just go to the site and fill out the form.

    The other good news is that the servicing mission is going ahead for early 2008 when they're going to put in WFPC3 which is a bit better than ACS and will have much lower distortions and a great new spectrograph called COS. That'll take HST to the end of its life in 2013. At that point, the next space telescope, JWST, will be launched. In case you're wondering though, JWST will have a much shorter life since it won't be possible to service it.

    So yeah, it sucks that ACS smoked itself but it's not the end of the world.
