February 13, 2005 EDITORIAL Death Sentence for the Hubble? Sean O'Keefe, the departing administrator of the National Aeronautics and Space Administration, has yanked the agency's most important scientific instrument off life support. His refusal to budget any funds to service and upgrade the Hubble Space Telescope looks like the petulant final act of an administrator who made a foolish decision and then refused to back down in the face of withering criticism from experts. The only uncertainty is whether the decision to let the Hubble die prematurely was solely Mr. O'Keefe's or reflects the judgment of higher-ups in the administration that servicing the Hubble would be a diversion from the president's long-range program of space exploration. The Hubble by all accounts has been one of the most productive instruments in the history of science, largely because periodic servicing missions by shuttle astronauts have extended its life and upgraded its instruments. A fifth servicing mission had been planned, and the new instruments already built, when the Columbia disaster grounded the three remaining shuttles for repairs. Then, without any warning, Mr. O'Keefe shocked scientists by announcing that the servicing mission would be canceled for good because it would be too risky. Nothing, it seems, can budge him from that snap judgment. When a dumbfounded Congress insisted that he seek advice from the National Academy of Sciences, he reluctantly agreed, but made it clear that nothing the academy said was apt to change his mind. He urged the academy instead to focus on ways to extend Hubble's usefulness without the help of astronauts. As it turned out, a panel of experts assembled by the academy concluded that there was little chance the robotic mission favored by Mr. O'Keefe could be mounted in time. The panel urged instead that astronauts be sent to the rescue. It judged such a flight only marginally more risky than a flight to the International Space Station. Undeterred, Mr. O'Keefe is now blaming the academy for sealing the Hubble's doom. He still insists that a shuttle flight would be too risky, mostly because there would be no place to take refuge should problems arise, and now he complains that a robotic mission would be impractical as well because the academy dismissed its prospects for success. So he has wiped the budget clean of all rescue funds except for a future robotic mission to ensure that Hubble falls out of orbit safely. Congress, which declared in a conference report last year that servicing the Hubble should be one of NASA's highest priorities, needs to order NASA to keep planning for a rescue mission. Some legislators may wonder if a servicing mission is worth the effort, given recent testimony by eminent scientists that they would be reluctant to see NASA's science programs socked with $1 billion to $2 billion in charges for the Hubble rescue - a huge sum that would disrupt other high-priority programs - but would consider $300 million to $400 million acceptable. That bookkeeping issue is a diversion. The refurbished shuttles will eventually return to flight, and the marginal cost for sending one to the Hubble would not be prohibitive. Upgrading the Hubble is probably the most important contribution today's astronauts could make. |

That's ok, the NGST will be many times better.

"Our heroic cosmanauts must undertand that the State demand sacrifices..." Sorry, about that - wrong station. Seriously, if you are going to say that there is no reason not to do a Hubble visit, you need to address the safety issue - as some on this group have done. The article above is poorly researched because of this. |

The article above is poorly researched because of this. The expected risk cost is ~0.1 lives and 0.015 shuttles (assuming a 1/70 chance of disaster with each shuttle mission not to ISS). The deaths are equivalent to ~12 million passenger miles of automotive travel, or every member of the American Astronomical Society driving 2000 miles, or every U.S. amateur astronomer driving about a dozen miles, or every person who has ever looked at a Hubble picture and thought 'wow! that's cool' driving a few hundred meters. Or to put it another way, it's equivalent to each of the seven astronauts who decide that they are willing to risk a Shuttle flight to fix Hubble doing so. Now that the safety issue has been addressed (although not compared to that of the dozens of planned trips to the ISS, with only a marginal increase in safety per flight) let's go and fix it. -- David M.

The article above is poorly researched because of this. The expected risk cost is ~0.1 lives and 0.015 shuttles (assuming a 1/70 chance of disaster with each shuttle mission not to ISS). Recalculate for 1/50 That is the current safety rating. It's not a safety issue. It is quite a bit of a project management issue. The 2007 launch to Hubble would be right in the middle of ISS flights. They would have to take a shuttle offline and do a one-off flight to another destination. If they go with a safety net of a spare shuttle, then you have created a gap of a couple months when ISS construction and processing is interrupted. It's also a 40% chance of vehicle loss over the remaining number of flights, to where no one individual flight is more risky than any other, it is the aggregate total that is the issue. Without ISS, shuttle would be permamently grounded already. There is zero push to get it back into service for anything else. The deaths are equivalent to ~12 million passenger miles of automotive travel, or every member of the American Astronomical Society driving 2000 miles, or every U.S. amateur astronomer driving about a dozen miles, or every person who has ever looked at a Hubble picture and thought 'wow! that's cool' driving a few hundred meters.

Recalculate for 1/50 That is the current safety rating. According to whom? Cite your sources, please. At *worst*, it's 1/56.5 (+ post-CAIB safety improvements). *Reasonably*, it's 1/88, (+ post-CAIB safety improvements). Again, *cite* your sources, if you have any. -- JRF Reply-to address spam-proofed - to reply by E-mail, check "Organization" (I am not assimilated) and think one step ahead of IBM. |
