"In February, 2003, space shuttle Columbia was lost upon atmospheric re-entry. Afterward, NASA commissioned an exhaustive investigation to figure out what happened, and how it could be prevented in the future. However, they also figured out exactly what would have been required for a repair and rescue mission using Atlantis. Lee Hutchinson at Ars Technica went through the report and wrote a lengthy article explaining what such a mission would look like. In short: risky and terribly complex — but possible. 'In order to push Atlantis through processing in time, a number of standard checks would have to be abandoned. The expedited OPF processing would get Atlantis into the Vehicle Assembly Building in just six days, and the 24/7 prep work would then shave an additional day off the amount of time it takes to get Atlantis mated to its external tank and boosters. After only four days in the Vehicle Assembly Building, one of the two Crawler-Transporters would haul Atlantis out to Launch Complex 39, where it would stage on either Pad A or Pad B on Flight Day 15—January 30. ... Once on the pad, the final push to launch would begin. There would be no practice countdown for the astronauts chosen to fly the mission, nor would there be extra fuel leak tests. Prior to this launch, the shortest time a shuttle had spent on the launch pad was 14 days; the pad crews closing out Atlantis would have only 11 days to get it ready to fly.'"Read Replies (0)

"The Mercury News' Mike Cassidy reports that women are missing out on lucrative careers in computer science. 'The dearth of women in computing,' writes Cassidy, 'has the potential to slow the U.S. economy, which needs more students in the pipeline to feed its need for more programmers. It harms women by excluding them from some of the best jobs in the country. And it damages U.S. companies, which studies show would benefit from more diverse teams.' The promise of better financial results, says Anita Borg Institute Director Denise Gammal, is making diversity a business imperative. It's 'the sort of imperative that cries out for a movement,' argues Cassidy, 'maybe this time one led not by Rosie the Riveter, but by Peggy the Programmer.' So, where will Peggy the Programmer come from? Well, Google is offering $100 to girls attending U.S. public high schools who complete a Codecademy JavaScript course. 'Currently only 12% of computer science graduates are women,' explains Codecademy, 'and great tech companies like Google want to see more smart girls like you enter this awesome profession!' Google joins tech giant-backed Code.org in incentivizing teachers to bring the next generation of girls to the CS table.

"The number of known planets beyond the solar system took a giant leap thanks to a new technique that verifies candidate planets found by NASA's Kepler space telescope in batches rather than one-by-one. The new method adds 715 planets to Kepler's list of confirmed planets, which previously totaled 246, scientists said Wednesday. Combined with other telescopes' finds, the overall exoplanet headcount now reaches nearly 1,700. 'By moving ... to statistical studies in a "big data" fashion, Kepler has showcased the diversity and types of planets present in our galaxy,' said astronomer Sara Seager."In other exoplanet news,
a recent study found that so-called 'super earths,' planets that are bigger than Earth but smaller than gas giants like Uranus and Neptune, are
unlikely to be habitable to known forms of life. The higher mass traps significantly more hydrogen during the formation of the planetary system, which results in extremely high atmospheric pressure — high enough to be hostile to known life.

"Alexis Madrigal at the Atlantic: 'The marvelous thing about horseshoe crab blood, though, isn't the color. It's a chemical found only in the amoebocytes of its blood cells that can detect mere traces of bacterial presence and trap them in inescapable clots.' Madrigal continues, 'To take advantage of this biological idiosyncrasy, pharmaceutical companies burst the cells that contain the chemical, called coagulogen. Then, they can use the coagulogen to detect contamination in any solution that might come into contact with blood. If there are dangerous bacterial endotoxins in the liquid—even at a concentration of one part per trillion—the horseshoe crab blood extract will go to work, turning the solution into what scientist Fred Bang, who co-discovered the substance, called a "gel." ... I don't know about you, but the idea that every single person in America who has ever had an injection has been protected because we harvest the blood of a forgettable sea creature with a hidden chemical superpower makes me feel a little bit crazy. This scenario is not even sci-fi, it's postmodern technology.'"Read Replies (0)

The latest title in the stealth game series
Thief launched in North America yesterday for the PS3, PS4, Xbox 360, Xbox One, and Windows. Reviews of the game are mixed. Rock, Paper, Shotgun's John Walker says that the story is poor, but "it matters very little, since it's only there as
an excuse to link epic, intricate and hugely enjoyable levels together." He also laments the loss of a dedicated "Jump" button, noting that veterans of the series will miss it. "There are far too often obstacles that a toddler could easily scale, but Garrett won't even try, and his refusing to jump certain gaps in order to force a challenge is maddening." Polygon's review says navigating the game's open environments was fun, but "In the latter half of the game, when a glimpse of that openness was dangled in front of me once again,
Thief snatched it away with murderous AI and controls that didn't feel up to the challenge." They add, "a new obsession with scripted story sequences and stealth action often
leaves Thief feeling like the worst of both worlds." Giant Bomb's review is brutal, saying
Thief is "a game that
spends an inordinate amount of time making the player do uninteresting things while shoving the more fun stuff so far in the corner you'd be forgiven for missing most of it."
