Poor Spirit

It’s been an amazing six years for the Martian rover Spirit. But the little robot may finally be dying in winter temps of almost seventy degrees below zero F. It hasn’t been heard from since March 22:

“The earliest date the rover could generate enough power to send a beep to Earth was calculated to be around July 23. However, mission managers don’t anticipate the batteries will charge adequately until late September to mid-October. It may be even later if the rover is in a mission-clock fault mode. If Spirit does wake up, mission managers will do a complete health check on the rover’s instruments and electronics.”

Hang in there, Spirit. Spring’s coming.

Iowahawk on the Volt: Infantile ads

Nevermind the $41,000 pricetag. Government Motors’ new Chevy Volt irks car-nut Iowahawk just for its cheesy advertising. “See the U.S.A., etc.” this is not. Buy a Ford, he says, for better songs. Me, I’ll stick with Honda, and skip the ads altogether.

Hubble bubble

“Now it is also possible that our entire observable Universe is a Hubble bubble, but that really flies in the face in all of cosmology. It is unfounded, absurd, and really the whole idea of a Hubble bubble may explain dark energy, but is hardly a very good explanation.”

Messenger at Mercury

“Every time we’ve encountered Mercury, we’ve discovered new phenomena,” said Sean Solomon, the [NASA] mission’s principal investigator at the Carnegie Institution of Washington. “We’re learning that Mercury is an extremely dynamic planet, and it has been so throughout its history. After MESSENGER has been safely inserted into orbit around Mercury next March, we’ll be in for a terrific show.”

The Flying Barrel

F3f3oClockResearching my book on radar development in Texas, I encountered the Grumman F-3F, the last American military biplane fighter. Nevermind why. Pilots called it the “Flying Barrel,” not very affectionately would be my guess.

Vitals

This is one paranoid hard SF novel by Greg Bear. A clear majority of his Amazon critics seemed to hate it. I rather enjoyed it, but it certainly was a weirdie. Did you know Stalin was still alive, barely, in a bacteria-filled tank in Manhattan?

Good thing I’m not a conspiracy buff, into things like government mind control. Otherwise I could be losing sleep over this one. Instead, I always remember the words of an old friend who retired from fed law enforcement: “They (the feds) couldn’t find their own posterior with both hands.” Or the Russians, either, who are the real bad guys in this one.

Darwin’s Children

I enjoyed this sequel to Greg Bear’s Darwin’s Radio—only about $12 for both on the Kindle. The sequel was as touching and affective as the first novel. I also appreciated the hard-science plot and the definitions and sources in  the back of DC. I had spent a fair amount of reading time wondering how much of the whole genomic story of the creation of a new sub species of Homo could possibly ever happen all at once like that.

Not much chance, apparently, though Bear makes clear that molecular biologists aren’t all that sure. (Somehow I had overlooked the genetic origin of viruses and that, alone, was worth the price of admission.) I also enjoyed his surprising conjoining of science and belief. Nicely done.

I could have done without the villainy attached to the Republicans and FoxNews. As I recall, when SF masters like Heinlein blamed pols, they did not specify party and used fictitious journalists as stand-ins for the industry.

I wonder why modern SF writers like Bear (and Stross, to name another who also does it) don’t follow suit but, instead, feel the need to push their personal politics in their readers’ faces. Sign of the times, I suppose, or maybe their editors/publishers require it. That wouldn’t surprise me. Still, despite this flaw (neither book wallows in it), both were worthy, absorbing tales I recommend to all.
