SpaceX has shifted from composite to stainless steel, and will do initial flight tests “early next year.”

The Earthrise Image
Bob Zimmerman says it wasn’t “rising.”
[Update at noon on Christmas day]
Half a century after shooting the picture, reflections from Bill Anders (who heartily endorsed my book at a NASA meeting a couple years ago).
[Bumped]
Mike Griffin
For Secretary of Defense?
I agree that we need someone who understands the technology threat at the helm of the Pentagon. But I wonder how familiar Goldman is with Griffin’s actual record when I read “praise” like this:
The overriding strategic risk to the United States is the loss of our technological edge, and the Defense Department needs a leader with the vision and expertise to restore it. Michael Griffin would be an excellent choice. A first-rate physicist, Dr. Griffin headed NASA under the Bush 41 administration.
First, Mike knows physics, but I wouldn’t call him a “physicist.” He’s first and foremost an aerospace engineer (not that there’s anything wrong with that). The problem is that, during his tenure at NASA, he devastated the space R&D budgets and promoted Constellation, an attempt not to develop needed new technology, but to repeat Apollo (except this time “on steroids”) with decades-old technology based on Saturn and the Space Shuttle.
At the time he left the agency (unwillingly) in 2009, all that was being developed to get back to the moon was a rocket designed to carry a capsule into low earth orbit, with no serious plans for things like a lunar lander, and those items were far over budget, and slipping more than a year per year (one of the reasons that, almost a decade later, we remain dependent on the Russians for access to our own space station). Even if they’d succeeded, the planned flight rate would be very low, at ridiculously high cost.
Now, in theory, he could argue that he is now older and wiser, and learned his lesson from that, but that’s negated by the fact that he continues to support their successors, the SLS and Orion. So, if we need someone to restore our technological edge, it’s hard to make the case that he’s the right guy for the job.
[Update a while later]
OK, if Mike Griffin were SecDef, just what would he do, going on past performance? Would he propose a giant expendable combat aircraft, based on parts from F-15s and F-16s, that would fly once a year, and each service could take a turn?
Apollo 8
Half a century ago today, a spaceship left earth to take astronauts not just beyond LEO, but all the way to and around the moon. That was when we won the race.
Bob Zimmerman reflects.
[Update Sunday morning]
More thoughts from John Wenz. This statement isn’t inaccurate, but it is a little misleading:
It was the first time humanity had orbited another body that wasn’t our home planet.
Yes, it was, but some have concluded from that fact that they weren’t orbiting earth. None of the Apollo missions left earth orbit, because they never reached escape velocity, and when you orbit a moon that is in orbit around a planet, you remain in orbit around that planet along with it. No human has ever left earth orbit, but Elon seems to have the most serious plans to do so.
One other point, unrelated to Wentz’s piece. I was looking at the Wikipedia page for the mission, and found this bit of (misleading, at best) history:
On August 9, 1968, Low discussed the idea with Gilruth, Flight Director Chris Kraft, and the Director of Flight Crew Operations, Donald Slayton. They then flew to the Marshall Space Flight Center (MSFC) in Huntsville, Alabama, where they met with KSC Director Kurt Debus, Apollo Program Director Samuel C. Phillips, Rocco Petrone, and Wernher von Braun. Kraft considered the proposal feasible from a flight control standpoint; Debus and Petrone agreed that the next Saturn V, AS-503, could be made ready by December 1; and von Braun was confident that the pogo oscillation problems that had afflicted Apollo 6 had been fixed. Almost every senior manager at NASA agreed with this new mission, citing confidence in both the hardware and the personnel, along with the potential for a circumlunar flight providing a significant morale boost. The only person who needed some convincing was James E. Webb, the NASA administrator. Backed by the full support of his agency, Webb authorized the mission. Apollo 8 was officially changed from a “D” mission to a “C-Prime” lunar-orbit mission.
Webb may have authorized it in August, in the sense of changing the mission category, but this was probably to keep the option open, not because he supported doing it. I’m pretty sure he continued to oppose it, and it may be that one of the reasons for his retirement in October was to not have it happen on his watch (though he probably would have left anyway in the New Year, with the incoming administration of Nixon). Tom Paine (who did favor it), as Acting Administrator, actually made final approval in November, a few weeks before the flight.
The Space Frontier Act
It passed the Senate. I like the name, but the Lefties will hate it. I’m glad that the Office of Space Commerce is no longer under NOAA (I had discussed that issue with Jason Kim at lunch during the Galloway Symposium a couple weeks ago), and I don’t think we have to assign regulatory authority to it yet. Before we do that, we need to understand very clearly exactly what orbital activities are being regulated. Unfortunately, it’s unclear whether it will get through the House before the session ends.
[Update late morning]
Apparently the House is voting for it today, under suspended rules (they’ve pre-reconciled with the Senate), so it looks like it will go through as is.
Curiosity’s Future Travels
For those into Mars, Bob Zimmerman has a post up with some speculation.
Dissing Virgin Galactic
You can find a NASA astronaut to come up with any opinion you want, but Andy Thomas isn’t impressed with SpaceShipTwo. I share the criticisms (which were made by me and others when the SpaceShipOne concept was first revealed), but I don’t think it’s doomed to failure. It offers a different experience than New Shepard, and will have its own market. I continue to find it ironic that the systems Burt added for “safety” probably added hazards instead.
Reproduction On Mars
Nadia Drake has the latest. We continue to not have a gravity lab to study this.
[Update after reading the whole thing]
They seem to be proposing a gravity lab (still unfunded), but they want to put it in lunar orbit. I see no reason to do this, other than to give the Gateway something to do; LEO (and probably in the ISS orbit) makes a lot more sense to me.
Jeff Bezos
An interesting space-related profile from Princeton, his alma mater.
I did an interview a few months ago for the upcoming documentary, even though I didn’t really know O’Neill (I met him once). He had a large indirect influence on my life. The last question I was asked was what single word came to mind when I thought about him. My answer: “Hope.”
[Afternoon update]
It’s important to understand that The High Frontier came out in the mid-70s, a time of doom and gloom. Paul Ehrlich and the Club of Rome were always banging on about overpopulation and running out of resources, and instead of global warming, we were supposed to be worried about a return of the glaciers. In addition to O’Neill’s book, Peter Vajk (himself inspired by O’Neill) came out with a book meant to be a palliative, titled Doomsday Has Been Canceled. Anyway, that’s the context in which I said that he brought hope.
