Evolution Coming to Space Race

Posted Jan 9, 08 2:33 PM CST in Science & Health 

(Newser) – Engineers have devised a way of coming up with flight paths for space missions by using the laws of natural selection, Space.com reports. An algorithm called "differential evolution" treats different paths as individual organisms, which then "mutate," and the best solutions survive to the next generation. Engineers behind differential evolution hope NASA and other agencies consider using the method in future.

"I think it'd be nice if NASA would like to put it in their toolbox," one says. As a test, the creators of differential evolution used the algorithm to come up with an ideal flight plan for the goals of the Cassini mission to Saturn. "The Cassini results were actually very close to what was actually flown," says engineer Craig Kluever.

    New Rover Won't Hit Mars Until 2011 NASA is delaying the launch of its next Mars rover, which is significantly larger and more complex than previous models, until 2011, Space.com reports. The Mars Science Laboratory was set to arrive on the red planet next year, but problems with crucial mechanical components mean it will miss its tight launch window. “We're really only a few months behind schedule, not two years behind schedule,” said the director of the exploration program.

    Saturn's Moon Hints at Water Plumes of gas and dust firing off one of Saturn's moons are moving at speeds “hard to do without liquids,” astronomers say, strongly suggesting the presence of water and raising the possibility of the moon supporting life. As Enceladus continues “helpfully spewing out its innards,” evidence of liquid H2O “is building,” a scientist tells the AP.

    Private Firms Hope to Haul NASA's Space Cargo Hauling crew and equipment between earth and the international space station is expensive work, and NASA is looking to private entrepreneurs to pick up some of the slack, the Washington Post reports. Among the front-runners is Elon Musk, a founder of Paypal, who has seen his three prototype shuttles crash before they could make it into orbit.

    There's a New Space Race, and US Is Losing While the rest of the world cooperates incessantly on all matters extraterrestrial, the US, hampered by self-imposed regulations meant to keep weapons out of enemies' hands, is swiftly losing dominance of the final frontier, the Washington Post reports. The US’ military space program is still gargantuan, but the civil program, NASA included, suffers from “limited public interest in space activity.” More »
