Pulling an Airbus’s plug

Bad things can happen when the Airbus’s electrical systems go out:

"Simply, the Airbus 330 is one of the few commercial aircraft that is completely fly-by-wire [i.e., fully automated by computer]. The Airbus 320, of Hudson River fame, has mechanical backups, but the Airbus 330 and 340 don’t."

So when their computers quit, what’s left? Exactly nothing. Not much. Except, uh, prayer.

Sunspecks

Scientists are getting so desperate for the return of sunspots that they are now counting sunspecks. The one on the left is fading away, the one in the middle is a "dead pixel," an artifact of the SOHO spacecraft, and the two on the right are the latest candidates for sunspots. I’m wondering if the lack of activity will mean a cooler-than-usual summer. Well, I can dream, anyhow, as our daytime temps at the rancho climb steadily into the 90s.

Happy Belated Towel Day

And, above all, whatever you do, as Douglas Adams would say (did say, in fact): Don’t Panic.

Map reading

If the Air Force isn’t telling the truth and the GPS system does go down, it would mean chaos for the aviation industry. Me, I could always go back to map and compass. I taught both as a counselor in Boy Scouts many moons ago. But I’ll keep my fingers crossed that the sat system isn’t really in jeopardy.

Cause we like our TomTom. We use the Jane voice, which is British. You have to remember to update the memory every so often. But even when the route she suggests is more circuitous than we like, she picks up on where we’re going and adjusts her guidance. Lots easier than when Mrs. Charm navigates.

Death Star Galaxy

The ole Hubble has imaged a lot of strange beasts since it was launched nineteen years ago. This is one of the strangest, part of a slide show collection at The Daily Beast and explained there.

Shuttle mission

Watch the STS 125 Atlantis astronauts make the final visit to the Hubble Space Telescope live on NASA TV. It’s hard to overstate the beauty and scientific value of the Hubble’s nineteen years of discoveries.

Enjoy it while you can. As the Seablogger puts it "The remaining shuttles are soon to be retired, and no replacement is likely. I suspect much of the space program will be terminated as health care and other costs overwhelm the federal budget." That does seem likely, and that Barry will be content to grovel in the mud.
