Scientists Discover That Mars is Full of Water | Surprising Science | Smithsonian Magazine - 0 views

  • Now, according to an article published yesterday in the journal Geology, there is evidence that Mars is home to vast reservoirs of water in its interior as well.
  • The amount of water in the meteorites suggested that the Martian mantle contains somewhere between 70 and 300 parts per million of water—an amount strikingly similar to Earth’s own mantle. Because both the samples contained roughly the same water content despite their different geological histories on Mars, the researchers believe that the planet incorporated this water long ago, during the early stages of its formation. The paper also provides us with an answer for how underground water may have made its way to the Martian surface: volcanic activity.

NASA gets two military spy telescopes for astronomy - The Washington Post - 0 views

  • NASA officials stressed that they do not have a program to launch even one telescope at the moment, and that at the very earliest, under reasonable budgets, it would be 2020 before one of the two gifted telescopes could be in order. Asked whether anyone at NASA was popping champagne, the agency’s head of science, John Grunsfeld, answered, “We never pop champagne here; our budgets are too tight.”
  • The unexpected gift offers NASA an opportunity to resurrect a plan to launch a new telescope to study the mysterious “dark energy” that is causing the universe’s expansion to accelerate.
  • The two new telescopes — which so far don’t even have names, other than Telescope One and Telescope Two — would be ready to go into space but for two hitches
  • ...3 more annotations...
  • First, they don’t have instruments. There are no cameras, spectrographs or other instruments that a space telescope typically needs.
  • Second, they don’t have a program, a mission or a staff behind them. They’re just hardware.
  • “Instead of losing a terrific telescope, you now have two telescopes even better to replace it with,” Spergel said.

NASA's Kepler Announces 11 Planetary Systems Hosting 26 Planets - Mainpage - 0 views

  • NASA's Kepler mission has discovered 11 new planetary systems hosting 26 confirmed planets. These discoveries nearly double the number of verified planets and triple the number of stars known to have more than one planet that transits, or passes in front of, the star.
  • The planets orbit their host star once every six to 143 days. All are closer to their host star than Venus is to our sun.

Mystery: U.S X-37B space plane has been in orbit for over a year | Mail Online - 0 views

  • Last May, amateur astronomers were able to detect the orbital pattern of the first X-37B which included flyovers of North Korea, Iraq, Iran, Pakistan and Afghanistan, heightening the suspicion that the vehicle was being used for surveillance.
  • Other industry analysts have speculated that the Air Force is just making use of the X-37B’s amazing fuel efficiency and keeping it in space for as long as possible to show off its credentials and protect it from budget cuts.

Secret Military Mini-Shuttle Marks One Year in Orbit : Discovery News - 0 views

  • The military won't say what it has been doing with its experimental miniature space shuttle, but the pilotless spaceship, known as the X-37B, has been in orbit for a year now. The 29-foot robotic spacecraft, also known as the Orbital Test Vehicle, or OTV, was launched on March 5, 2011, on a follow-up flight to extend capabilities demonstrated by a sistership during a 244-day debut mission in 2010.
  • "The X-37B program is setting the standard for a reusable space plane and, on this one-year orbital milestone, has returned great value on the experimental investment,"
  • Amateur satellite watchers last spotted the spaceship on March 4 as it circled between 204 and 212 miles above the planet in an orbit inclined 42.8 degrees relative to the equator.

  • "Ground tracks that repeat every two to four days are a common feature of U.S. imagery intelligence satellites," Molczan said. "It gives you a fairly frequent revisit of the same targets from the same vantage point."

Faster-than-light neutrino result reportedly a mistake caused by loose cable - 0 views

  • a loose fiber optic cable was causing one of the atomic clocks used to time the neutrinos' flight to produce spurious results.
  • If the report is confirmed (right now, there's only one source), then it provides a simple explanation for the fascinating-yet-difficult-to-accept results.
