Worth the Risks?

Are NASA’s Human Shuttle Flights Worth the Risk?

WASHINGTON (Reuters) – There’s little doubt that NASA (news – web sites) can get its space shuttles flying again, but seven months after the deadly Columbia accident, there are plenty of doubts about whether it should.

True, and those doubts were expressed even before the Columbia accident. The reality is that we are stuck with Shuttle in the near term, unless we plan to mothball or abandon ISS and put human spaceflight on the promise of OSP (or something else) becoming available soon.

With no clear vision for why the United States is pursuing human space flight, a tight national budget and a scathing critique of the U.S. space agency’s “broken safety culture” coloring the debate, some in Congress wonder if sending humans into space at this point is worth the risk.

The first sentence answers the the question in the last. No, it isn’t worth the risks to send humans into space if there is no clear vision for sending them there. Hence the calls for a new goal for NASA (namely, Mars).

“We’re putting American men and women at great risk for their lives, flying orbiters that are 30 years old that cannot be made safe,” Rep. Joe Barton, a Texas Republican, told NASA chief Sean O’Keefe at a congressional hearing. “My proposal is … to use these orbiters in an unmanned capacity, build a new space plane or space orbiter that’s just for people.”

Yeah, right, Joe. It’s going to take 3-5 years for OSP to get to its first test flight, if it makes it that far. Are you and your pals in Congress willing to pony up the cash for the Russians to launch our astronauts to ISS in the meantime?

Another Texan, Democratic Rep. Ralph Hall, pushed O’Keefe to commit to developing an escape vessel for shuttle crews.

Stupid idea, if he’s thinking of a jettisonable cabin, ejection seats, or the host of other retrofits which have been proposed over the years. By the time you tear apart the three remaining Orbiters and retrofit them with some no-doubt hideously expensive escape system, you might just as well build all new vehicles.

But perhaps Sen. Sam Brownback, a Kansas Republican, put the question most starkly at an earlier hearing: “Are we throwing good money after bad?”

Yes. But the time to have asked that question was back in 1986. Or 1972. But since your colleagues and predecessors didn’t, we’re stuck with Shuttle for now, and it’s going to cost a good bit of money to fix the problems. If, that is, we intend to keep sending humans into space through the near term.

So far, recovery from the Feb. 1 Columbia disaster has cost nearly $400 million, about the price of one shuttle launch. This does not include changes to the shuttle program recommended by the independent Columbia Accident Investigation Board in its highly critical report released on Aug. 26.

As is so often the case in government, they can find the money to pick up the pieces and fix the problems after something catastrophic happens, but can’t be bothered beforehand.

Yet even as the board flayed the U.S. space agency for its skimpy budgets, uneven safety record and habit of turning a deaf ear to engineers’ concerns, the final report presumed that “the United States wants to retain a continuing capability to send people into space, whether to Earth orbit or beyond.”

That’s the general assumption, yes. But as noted above, there is no clear vision for why we should want to do so.

How Safe is Safe Enough?

Rand Simberg points to a brief article by Ronald Bailey at ReasonOnline: Making Spaceflight Too Safe?

Reading this, I’m reminded of a quote which I’ve quoted here before:

Deep in the sea are riches beyond compare, but if you seek safety, it is on the shore.

Rereading my earlier post, I realized that I failed to make the connection to private efforts. Bailey makes this connection, pointing out that a new generation of safer spacecraft will only come about through competition in the marketplace:

The CAIB has identified technical safety problems, and they will be fixed. But the report also recommends that NASA create “an independent Technical Engineering Authority” that would be in charge of shuttle safety. Adding a new managerial layer of scared, risk-averse bureaucrats is just rearranging the deck chairs on the Titanic. We all know what really works?competition.

Competition focuses the minds of even the stodgiest technocrats. So let’s end NASA’s monopoly on human space flight. Let the private sector design, test and fly innovative, cheaper, and yes, safer spacecraft.

Amen. It’s time to turn over LEO to the startups.

CAIB Report

As you probably already know (this being posted late in the day) the CAIB report has been released.

Should make for some interesting reading…when I actually have the time to read it. Meanwhile, Rand Simberg, who is far more capable of this than I, will be posting commentary on it as he reads.

Update: I know this is a trivial observation, but in flipping through the introduction, I’m impressed with the quality of photographs chosen from STS-107. Some, including the final liftoff, the Sinai, and the Moon on Earth’s limb, are stunning.

One More Barn Door Closed

NASA is considering landing the orbiters at Edwards instead of KSC, in order to avoid another reentry breakup dumping debris over populated areas.

No Rescue Would Be Coming

Rand Simberg comments on the latest outbreak of the “We could have saved Columbia” meme.

He makes a good point regarding the notion of using Atlantis for a rescue mission. Sure, the launch preparation procedures could have been junked and Atlantis fired off, if the necessity had been recognized early enough and the order to do so had been given. But there would have been as much or more of a chance of losing both orbiters thereby as there would have been of successfully rescuing the Columbia crew before time ran out. And had that happened, it could have easily meant the end of the U.S. manned space program (at least for a good long while).

Which makes me all the more concerned that the accident will have no serious, positive impact on the “quest” for a replacement for the Shuttle…that business-as-usual will continue at NASA until we lose yet another orbiter.

This Guy is Supposed to Be Funny?

Tom Lehrer has some rather blunt opinions about the Columbia disaster, and manned spaceflight in general:

“They are calling it a disaster instead of a screw-up, which is all it was. They’re calling these people heroes. The Columbia isn’t a disaster. The disaster is that they’re continuing this stupid program.

“One of the things I’m proudest of is, on my record That Was the Year that Was in 1965, I made a joke about spending $20 billion sending some clown to the moon.

“I was against the manned space program then and I’m even more against it now, that whole waste of money. And so, when seven people blow up or become confetti, then they’ve asked for it. They’re volunteers, for one thing.”

No Time to Cut and Run

Bob Zubrin has an op-ed in Sunday’s St. Petersburg Times.

It’s about the kind of talk you would expect from Bob — passionate, stirring, and focused on Mars as the objective.

Perhaps if enough advocates push Mars as the destination, we can plant those trees in some realistic timeframe.
