Orion’s Molecular Cloud Complex

The part of Orion the Hunter you can’t see with the unaided eye or a cheap backyard telescope.

Red Mars

I finally got hold of this first novel in Kim Stanley Robinson’s 1990s Mars triology. Now I understand what the fuss was about over this series of tales which still sell well on Amazon. As the cover blurb on the 1993 edition, by Arthur C. Clarke, has it: "It should be required reading for the colonists of the next century." Well here we are in that century and polls show and pols say there’s not enough interest in going to Mars to bother.

The novel is still good. It’s light on the tech and the sci but heavy on the human relationships among the First Hundred colonists of Americans and Russians. And their one-way vehicle to Mars in 2026 (still time for that) is nicely practical: a cluster of rotating toruses made of interconnected fuel tanks from shuttle stacks taken into orbit (rather than discarded over the ocean) by both the American shuttle (retiring next year) and the old Soviet one (which only flew a few times).

So that’s impossible, but day-to-day life on Mars nevertheless is compelling. The tale makes me want to put on my "walker" and helmet and go for a lope in the low g, guided by a personal AI on my wrist, even if the Net is still confined to pre-Web bulletin boards. Among my favorite tech description is the building and subsequent use of a space elevator between Pavonis Mons and a captured asteroid. Thirty-story elevator cars make the journey up and down in five days.

Once out of the Mars gravity well, it’s much simpler (and cheaper) to board a rocket for earth, or arrive on one and take an elevator down to the planet. Now I’ll go back and reread the second book and finish the third one, with much more appreciation than I had trying to read them first.

Cosmic ray storm

Sol’s protracted solar minimum, which began about 2007, has opened the inner solar system to the highest concentration of cosmic rays yet measured during the space age (about fifty years old).

Which should provide a good test of Danish scientist Henrik Svensmark’s theory that cosmic rays provide seed nuclei for the low-altitude clouds that keep Earth’s temperature low. The theory is an alternative to the carbon dioxide argument, in that fewer cosmic rays hitting Earth would mean fewer low-level clouds and thus correspondingly higher temperatures. If Svensmark’s theory–explained in his 2008 book The Chilling Stars–is correct, winters could become more severe. At least until Sol’s minimum turns back to maximum.

Green Mars

This is actually an infrared partial image of Mars in 1999, so the green doesn’t mean vegetation. But it fits one of the quartet of books I’ve been reading, Kim Stanley Robinson’s Mars trilogy and subsequent The Martians. Relying on the local library meant I started with Green Mars, book two, then tried the concluding volume Blue Mars.

Got bogged down in the interminable geological descriptions of both and so went on to The Martians. Meanwhile, I’ve reserved  the first book, Red Mars, so maybe I can finally figure it out. So far I don’t understand all the acclaim for this soap opera about the First Hundred settlers from Earth, and their children. But I’m interested enough to continue, which means something, I presume. It’s only boring in parts. Some of it is quite interesting.

Mars water we got

At least in ice at the poles. Now it appears it may also be available in ice at lower latitudes as well. Not that it matters to Obamalot. They ain’t willing to go there either. Gotta fix earth first, apparently. If it takes a thousand years.

Show me the water

We’ve heard several times that there may be water on Luna. In the form of ice on the surface, and, perhaps, some liquid underground. NASA is expected to unveil Thursday research showing "a lot of water" exists on the surface.

From the AAAS journal Science advancer to Science writers: "…three reports utilize data collected by three separate spacecrafts to provide evidence of hydroxyl (OH) or water – or both – on the surface of the Moon. These findings are forcing a reexamination of the notion that our Moon is completely dry."

If there is abundant water, it makes a colony more feasible, as well as the refueling of spacecraft for interplanetary travel. As it says here I’m ready to believe. Just show me the water.

UPDATE:  Here’s the NASA version. Suspiciously timely, given recent cancellation of back-to-the-moon? Naw.

Sol’s new spots

The sunspot drought hasn’t ended entirely yet, but these new Earth-size ones are the first in more than a year on the Earth-facing side of Sol. They’re a hopeful sign that we may not, afterall, be headed for more ice and cold than usual from the deepest solar minimum in almost a century.
