I just noticed he has one. Just added to the blogroll.

SpaceX
They got the go-ahead a while ago to start fueling. Things are on schedule, as far as I know.
[Update a little over an hour before launch]
Everything still progressing nominally.
Here’s some good technical background on SpaceX’s quest for reusability. Assuming it’s accurate (and I didn’t see any obvious problems), that is a great, detailed description of the Falcon 9 (and its history).
[Update after scrub]
They scrubbed, primarily (it seems) due to a range radar problem.
This is why SpaceX wants to go to Brownsville. Tired of depending on antique improperly-maintained hardware at CCAFS.

The Cape was down for weeks last spring for exactly the same radar issue: http://t.co/JLi4nC2sVQ This is unacceptable in 21st century.

A little background on the antiquity of range radar at both Eastern and Western Test Ranges: https://t.co/z8ThcgECuB Goes back to 50s.

In the 21st century, range tracking should be via GPS, not radar. For example, Kodiak Launch Complex doesn't require radar tracking.

No, I don’t have strong opinions about this at all…
Strength Training
I think that women should do it, as well as men, because as Mark Rippetoe says, strong people are harder to kill. But I’m particularly in favor of vaginal weight lifting.
On The Radio
OK, actually, on the telephone. I’ll be having a Ricochet discussion with John Walker in half an hour to talk space stuff (probably including today’s Falcon fly-back attempt, and the ASAP report).
To participate, call +1 712 432 0375, then enter the access code 139584# and confirm by pressing 1. To enter the access code, you may have to put your phone into tone dialing mode, which may not be the default if you’re on ISDN.
Here’s the link for Ricochet members (it’s behind the paywall).
[Update a couple hours later]
Here’s the audio, for those interested.
How SF Will Get Us To Mars
I disagree with this. He seems to be operating under the delusion that NASA is ever going to get anyone to Mars, and seemingly ignores the people with money who are working to do so.
The Hugo Wars
On the sad state of science fiction:
Wherever they emerge, social-justice warriors claim to be champions of diversity. But they always reveal themselves to be relentlessly hostile to it: they applaud people of different genders, races, and cultures just so long as those people all think the same way. Theirs is a diversity of the trivial; a diversity of skin-deep, ephemeral affiliations.
This is one of the reasons I haven’t read as much as I did when I was younger. And sadly, the situation is similar on many college campuses.
Artificial Intelligence
Our immortality, or our extinction?
I think that’s a matter of how you define “us.”
Lunar Property Rights
The FAA is taking the first step toward granting them (in a sense). It doesn’t say how big an exclusion zone would be provided. But this is unprecedented. I assume this topic will come up at the conference tomorrow or Thursday.
The Climate-Modeling Paradigm
How robust is it?
Not very. Certainly nowhere near enough to base policy on it.
I was very impressed by Bakker’s intellectual integrity and courage in tackling this topic in the 11th hour of completing his Ph.D. thesis. I am further impressed by his thesis advisors and committee members for allowing/supporting this. Bakker notes many critical comments from his committee members. I checked the list of committee members, one name jumped out at me – Arthur Petersen – who is a philosopher of science that has written about climate models. I suspect that the criticisms were more focused on strengthening the arguments, rather than ‘alarm’ over an essay that criticizes climate models. Kudos to the KNMI.
I seriously doubt that such a thesis would be possible in an atmospheric/oceanic/climate science department in the U.S. – whether the student would dare to tackle this, whether a faculty member would agree to supervise this, and whether a committee would ‘pass’ the thesis.
Epistemic closure.
[Update a few minutes later]
The alarming thing about climate alarmism:
In short, climate change is not worse than we thought. Some indicators are worse, but some are better. That doesn’t mean global warming is not a reality or not a problem. It definitely is. But the narrative that the world’s climate is changing from bad to worse is unhelpful alarmism, which prevents us from focusing on smart solutions.
A well-meaning environmentalist might argue that, because climate change is a reality, why not ramp up the rhetoric and focus on the bad news to make sure the public understands its importance. But isn’t that what has been done for the past 20 years? The public has been bombarded with dramatic headlines and apocalyptic photos of climate change and its consequences. Yet despite endless successions of climate summits, carbon emissions continue to rise, especially in rapidly developing countries like India, China and many African nations.
Because all of the hysteria, name calling and outright lies have appropriately destroyed their credibility.
ESA
Can it survive without a radical restructuring?
Nope. SpaceX is disrupting space programs all over the world.
