Submission + - Asteroid Vesta Covered in Hydrogen (space.com)

DevotedSkeptic writes: "The protoplanet Vesta, a large space rock in the solar system's asteroid belt, is covered with a surprising amount of hydrogen, and bits of Vesta may have rained down on Earth in the form of meteorites, NASA's Dawn probe has revealed.

Dawn spent more than a year orbiting Vesta, a behemoth 330-mile-wide asteroid that circles the sun between the orbits of Mars and Jupiter. Earlier this month, on Sept. 5, Dawn took its leave of Vesta to begin trekking to the even-larger space rock Ceres, which is categorized as a dwarf planet.

Meanwhile, though, scientists are still poring over the treasure trove of data on Vesta gathered by the probe, and two new studies are reported on Sept. 20 in the journal Science. In one, researchers report the findings of Dawn's Gamma Ray and Neutron Detector (GRAND), which mapped the elemental composition of Vesta's surface."

Congrats on joining the few members of the "50 mile high club", but I'll be a lot more impressed when the chinese get those people into a stable earth orbit and then return, not just breathe the thin air and then fall back... regardless of the sexual organs present in the cockpit. -_-

So is 10 days not a stable enough orbit for you :) from the report: The crew will stay in space for more than 10 days, during which time they will perform scientific experiments and the country’s first manual space docking — a complicated procedure that brings two vessels together in high-speed orbit.

Yeah, but they are talking about the region.

"With the central core of the SKA located in this south-western part of the country the remote antenna stations would be located on easterly and northerly log spirals up to 3000 km away (Namibia, Botswana, Mozambique, Madagascar Mauritius, Kenya and Ghana)." skatelescope.org
Piracy

App Store Piracy Losses Estimated At $459 Million 202

Posted by Soulskill from the arrr-me-hearties dept.
An anonymous reader passes along this quote from a report at 24/7 Wall St.: "There have been over 3 billion downloads since the inception of the App Store. Assuming the proportion of those that are paid apps falls in the middle of the Bernstein estimate, 17% or 510 million of these were paid applications. Based on our review of current information, paid applications have a piracy rate of around 75%. That supports the figure that for every paid download, there have been 3 pirated downloads. That puts the number of pirate downloads at 1.53 billion. If the average price of a paid application is $3, that is $4.59 billion dollars in losses split between Apple and the application developers. That is, of course, assuming that all of those pirates would have made purchases had the application not been available to them for free. This is almost certainly not the case. A fair estimate of the proportion of people who would have used the App Store if they did not use pirated applications is about 10%. This estimate yields about $459 million in lost revenue for Apple and application developers." A response posted at Mashable takes issue with some of the figures, particularly the 75% piracy rate. While such rates have been seen with game apps, it's unclear whether non-game apps suffer the same fate.
