A Penetrating Critique Of Reusable Launch Systems

…from people who currently make good money building expendable launch systems.

In other news, the Buggy Whip Manufacturers Association saw no future in these newfangled “horseless carriages.”

[Update a while later]

Bob Zimmerman has some thoughts on the lie that is Orion, while Eric Berger discusses the GAO concerns about its programmatics.

A New Suborbital Tourism Vehicle

This article is amusing:

CosmoCourse CEO Pavel Pushkin told Sputnik New Agency, he came up with the idea of suborbital tourism back in 2013 when he was working at Khrunichev State Research and Production Space Center.

“We were reviewing various concepts of commercial space rockets and came up with the idea of launching people into space via suborbital trajectory.”

Wow, as far back as 2013! What a visionary.

Note that it’s short on details.

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

Units: sectors of 1 * 512 = 512 bytes

/dev/sdd3 1312768 62333951 61021184 29.1G 83 Linux

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:

Disk /dev/sdd: 14.5 GiB, 15560867840 bytes, 30392320 sectors

Command (m for help): q

[root@new-host-5 raspberry]# mount -t auto /dev/sdd1 /tmp/rpi/boot/
mount: /dev/sdd1 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/sdd1,
missing codepage or helper program, or other error

In some cases useful info is found in syslog – try
dmesg | tail or so.

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.

Browser Problem

Somehow, I got directed to a web site called windowssecurityhealthalert.com (DO NOT GO THERE), that opened a new instance of Firefox. It has a popup with this kind of crap in it:

I’m running Linux.

Anyway, it won’t let me close it. Clicking on the upper-right X does nothing, and when I close the popup, it just repops. If it was Chrome I could kill the individual process for it, but Firefox only has a single process for tabs and instances. If I kill Firefox, it just comes back when I restart and restore. I cleared all cookies, but that didn’t help. Anyone know how to track down what’s allowing it to do this and killing it with extreme prejudice?

[Mid-afternoon update]

After a little research, I installed this add-on, which blocks trackers and javascript. Post installation, I was able to kill both the pop up and the instance.
