The vast waters of Mars

Mars, it seems, for all its dust, airlessness and radiation, could be a livable place, after all.

Hubble snaps a planet

The Hubble Space Telescope has made the first visible-light snapshot of a planet orbiting another star: Fomalhaut b circles the bright southern star Fomalhaut, just twenty-five light-years away in the constellation Piscis Australis, the "Southern Fish."

Magnetic portals

Cylindrical magnetic passageways about the width of Earth, depicted here with a measuring satellite in the foreground, open and close between Earth and the Sun every eight minutes. They allow tons of high-energy particles to flow one-way across ninety-three million miles as they form above the equator and then roll over the poles.

Satellites have flown through them, measured their dimensions and sensed the particles flowing past. Now scientists are studying the portals to see how they work and what they do. Among the unanswered questions: why do they form every eight minutes? Here’s betting they affect our climate a lot more than carbon dioxide does. 

The shrinking heliosphere

Nevermind global warming and rising seas, kiddies. The sun’s protective bubble around the solar system has lost twenty-five percent of its size in the past decade and it’s still weakening.

You can cap and trade carbon dioxide until you know what freezes over, but unless this heliospheric shrinking is cyclical, the knowledge of which is just out of our reach, we’ve got a big problem, Houston. Can you say DNA-destroying radiation?

Into the black

Some recent science fiction, particularly Saturn’s Children, by Charles Stross, offers a bleak assessment of humanity’s chances of colonizing the solar system. The choices, from the moon to Mars and possibly Jupiter’s moon Europa, are high-radiation, ugly places. So it’s not as inspiring as usual to hear of Stephen Hawking’s latest prediction that we have to move beyond the home planet to survive. Makes sense, of course, but where will we find the natural beauty and relative safety of the shielding atmosphere that we leave behind?

Saturn’s Children

I suppose eroticism has always been a part of science fiction, at least in the cover art, though I don’t recall any as explicit as this tale, where a femmebot created to serve humanity’s sexual needs is left to look for love in all the wrong places because humanity has long been extinct. Extinct by it’s own hand, in fact, not through war or environmental disaster, but through selfish unwillingness to replicate–life with pets, instead, and all those forty-two-inch flat-screen boob tubes, I suppose.

I’ve now read three of Stross’s works, this one, Halting State and Singularity Sky. While I enjoyed HS, which is more about the Internet’s future than robotics, and SS had its moments, Saturn’s Children was the most memorable. Not only, or even especially because of the eroticism, but because of the suprisingly bleak assessment of what life beyond Earth really would be like for "pink goo," us, in landscapes and interplanetary propulsion systems awash in deadly radiation where only robots with replaceable parts can thrive.
