AGW critic recovering

Turns out that scientist at the Copenhagen meeting who suffered a heart attack was Henrik Svensmark, author of a plausible book and much research behind it as to what (besides carbon dioxide), might be causing the global warming that may or may not actually be occurring.

Svensmark seems to be recovering from what seems to have been a malfunctioning pacemaker, according to this hard-to-read Google translation of a Danish newspaper account, posted by Anthony Watts. Svensmark believes that a lack of cosmic rays to provide the seed nuclei for the formation of clouds to keep the temperature low is behind whatever warming there is. Sol’s recent sleep apparently has upped the cosmic ray count, which Svensmark might say is bringing the recent early winters.

Dark As Day

This Charles Sheffield novel isn’t very satisfying at the end, but the journey is a lot of fun. Sheffield creates interesting characters, such as Milly Wu the SETI researcher, the Great Bat, the puzzle master, and Alex Ligon, the computer modeler. Then there’s Sebastian Birch, who has something wrong with him that isn’t ever quite explained. All set in the plausible (to me) world of the settled outer solar system, principally on the moons of Jupiter. I was sorry to learn that Sheffield, a theoretical physicist, died in 2002. This book, his last, is a sequel to Cold As Ice and the Ganymede Club. I’d happily read a dozen more set in this realm. Alas, it is not to be.

New Horizons: first visit to Pluto

Hope to be around to see the pictures when the New Horizons robot reaches Pluto in 2015. Course, some insist it should still be regarded as a planet.

Enceladus: Ice-Jet Plumes

On last weekend’s close flyby of Saturn’s moon, the Cassini robot photographed these giant plumes of ice venting on the sunlit edge. They suggest the existence of underground oceans on the ice world. Cassini also has a video of the auroras on Saturn’s poles, similar to those of earth.

Cold As Ice

I enjoyed this 1992 scifi novel of physicist Charles Sheffield’s, though it seemed unnecessarily complicated in the beginning. A little more action before establishing the seven main characters would have prevented me from putting it down so often. Sheffield died of brain cancer in 2002, which resonates because a good friend of Mrs. Charm’s is struggling with it. Seems to have it licked for the moment, though the odds of that lasting are very low.

I bring up Sheffield to point out how easy it is to fall into these stories of ordinary life in the solar system, as if we had gotten off the engineering dime and were actually living in/on Luna, Mars, and the Asteroid Belt. A lot of Cold As Ice occurs on (actually, under the surface of) Ganymede, which recalls Heinlein’s impossible young adult novel, Farmer In The Sky, which Mr. B. and I started as a bedtime story but never finished.

We had the space probe pictures and details of Jupiter’s radiation to consult, as Heinlein did not. Also life on (under, actually) Europa, which seems plausible, despite Sheffield’s scientific realism of the dangers of Jovian radiation. I hope all this verisimilitude means humanity really will do these things and not just wallow forever in political corruption and the threat of war. But a posed result of the latter is limned chillingly in Cold As Ice as one of the spurs for continued colonization.

Dusty Island Universe

Also called the Silver Dollar and the Sculptor. A mere ten million light years away, and about seventy thousand light years in diameter. No weekend trip, alas.

Mars as you’ve never seen it

Amazing what a high-resolution satellite camera can do. These are some details of the Abalos Undae sand dunes. Meanwhile, a permanent moon base gets another boost.
