Less than an hour to go for the next SES-9 launch attempt by SpaceX. Eric Berger has the story.

Hillary’s Latest Email Problems
John Schindler deconstructs the Gray Lady’s attempt to whitewash:
At the National Security Agency—where I used to work as a senior intelligence analyst, including as the technical director of NSA’s largest operational division—what outsiders call hacking is handled by a shadowy group called Tailored Access Operations that gets at the hard targets requiring actual cyber-break-ins. TAO are probably the best hackers on earth, but Russia and China are no slouches either, as demonstrated by their repeated infiltrations into protected U.S. Government computer networks in recent years.
However, unencrypted IT systems don’t need “hacking”—normal SIGINT interception will suffice. Ms. Clinton’s “private” email, which was wholly unencrypted for a time, was incredibly vulnerable to interception, since it was travelling unprotected on normal commercial networks, which is where SIGINT operators lurk, searching for nuggets of gold.
They hunt for data with search terms called “selectors”—a specific phone number, a chatroom handle, an email address: here Ms. Clinton’s use of the “clintonmail.com” server was the SIGINT equivalent of waving a huge “I’m right here” flag at hostile intelligence services. Since the number of spy agencies worldwide capable of advanced SIGINT operations numbers in the many dozens, with Russia and China in the top five, that Ms. Clinton’s emails wound up in the wrong hands is a very safe bet, as any experienced spy will attest.
The amount of ignorance on this issue spouted by her defenders is both staggering and terrifying.
This Morning’s Space Press Conference
I listened in by phone. Here‘s the white paper.
As one would expect, a consensus from thirteen space organizations is going to be mostly motherhood, and implicitly self contradictory. More after I’ve taken the time to go through it. Elliot Pulham said that the campaigns have received it with “gratitude and interest,” but as he said, the main goal is not so much to inject space into the campaigns as to prevent people from saying stupid things about it. Good luck with that.
Epigenetic Aging
We may be able to turn it off, and reverse it. I’ve always been amused by (in Clarke’s words) the “distinguished elderly [or not so elderly] scientists” who think that the laws of physics require our bodies to deteriorate over time.
Via Glenn, who has some further thoughts.
The Ignorant Idea That Won’t Go Away
No, we can’t “just” throw our trash into the sun.
But I hate when people use current launchers to demonstrate the cost of a massive space project. That’s not how it would be done. And I wish they’d simply say “the sun is the most expensive place to get in the solar system.” Because it is.
Reforming Space Policy
Space News has a story on Bridenstine’s proposed legislation.
I’ll have to take a look at the actual draft bill, but it has some good things, and some not so good. I don’t think that SSA should be simply handed over to the FAA. I don’t think that FAA should even be involved in launch licensing. If we’re going to be making radical changes in structure, it’s time to seriously consider a U.S. Space Guard.
Linux Problem
I’m trying to format a micro-SD to install Fedora on my Raspberry Pi 2. I’m following the instructions here.
But when I get to the part about building the swap partition, I’m getting an error message. This is the output of fdisk:
Command (m for help): p

Now here’s what happens when I run mkswap:
[root@new-host-5 raspberry]# mkswap /dev/sdd2
mkswap: error: swap area needs to be at least 40 KiB
I’ve tried searching for a similar issue, but am coming up empty. Anyone have any ideas?
[Update a while later]
OK, I’ve decided that it’s a bad SD. But now I’ve got a new problem; I can’t mount the W95 FAT32 boot partition:

It doesn’t work with “auto” or “vfat” either.
[Tuesday-morning update]
OK, not sure what the problem was, but after rebooting the machine, I managed to get it all to work. I haven’t actually tried booting the Pi, yet, though.
SpaceX SES-9 Launch
It’s been rescheduled for Tuesday. They’re hoping that the fourth time will be the charm.
I think this is an issue of lack of experience with subcooling the LOX. This is only the second flight of the new vehicle. With sufficient flight experience, they’ll get it down, I’m sure.
Space Access
The latest agenda (including Yours Truly) is up. It really is the best space conference for the buck.
