Scientists Discover Source of Moons Magnetism

Moon_Earth_NASA_AP.jpgA group of MIT researchers believe they have discovered the source of the moon’s magnetism, a puzzler that has baffled scientists since the 1970s when Apollo astronauts first brought moon rocks to Earth, Space.com reports.

“Earth’s rotating, iron core produces the planet’s magnetic field. But the moon does not have such a setup,” the report said. Instead, MIT scientists now believe that the Moon did in fact have a liquid core with a dynamo about 4.2 billion years ago. Most moon rocks lose their traces of magnetism when subjected to major shocks from impacts. But the scientists found their smoking gun by examining the oldest moon rock brought to Earth—by Harrison “Jack” Schmitt, the only geologist ever to walk on the moon, during the last lunar landing mission, Apollo 17, in 1972.

“Many people think that it’s the most interesting lunar rock,” said MIT’s Ben Weiss in the article; his team found traces of the original magnetic field using a commercial rock magnetometer equipped with a robotic system geared toward detecting faint traces of magnetism. The report said that the findings fit in with the prevailing theory that the moon was born when a Mars-sized body crashed into the Earth and blasted much of its crust into space, where it clumped together to form the moon.

President Obama…From Space!

While my dreams of a television action series featuring Barack Obama fighting intergalactic criminals in space have once again been put on hold, science has happily given us the next best thing: Obama, from Space.

Google’s Earth and Maps-making satellite, the Geo-Eye-1, was 423 miles above the earth’s surface yesterday, taking shots of President Obama’s historical inauguration ceremony. It was a clear day, and the shots are pretty impressive, featuring millions of viewers packed into the Washington Mall.

Scientists Discover Methane on Mars

Mars_NASA.jpgScientists have discovered methane in Mars’ atmosphere using NASA’s Infrared Telescope Facility and the W.M. Keck telescope—both in Mauna Kea, Hawaii—raising the possibility that life may have existed on the red planet, according to CNN.

No one is sure how long it’s been there, but NASA officials and scientists said that the methane could have come from subsurface microorganisms, geological activity, or even comets that struck the planet in the past.

“It’s time, it’s prudent that we begin to explore Mars looking for the possibility of a life form that’s exhaling methane,” said Lisa Pratt, professor of geological sciences at Indiana University, at a NASA news briefing Thursday.

NASA’s latest Mars mission, the Phoenix Mars Lander, recently came to an end after successfully verifying the presence of water-ice in the Martian subsurface, discovering small amounts of salts that could be nutrients for life, and seeing snow falling from clouds, according to the report. Recently, NASA celebrated its 50th anniversary.

CES 2009: Meades ETX-LS Telescope is Astronomy for Dummies

Is it just me, or is this space stuff like, total rocket science? Telescope manufacturer Meade is looking to take “all of the hassle and [put] in all the fun” of looking at cool stuff in the sky, with its new ETX-LS. This massive telescope has a slew of features that bring clear images to users who couldn’t locate a celestial body to save their lives.

The ETX-LS features Lightswitch Technology which lets users align the scope with the flip of a witch, using the Integrated Sensor Module and ECLIPS (Electronically Controlled Locate Identify Position System).

The telescope also features Advanced Coma-Free optics, an ECLIPS CCD for image capture, and the Autostar III hand-held controller, which features a database including more than 100,000 images.

Japanese Invent High Tech Space Diapers

Engineers all over the world have focused their vast brainpower to overcome one major obstacle—space pooping. The Japanese think they have a solution with their fancy new wearable toilet.

Indeed, this is a far cry from the glorified Depends former NASA astronaut Lisa Nowak drove cross country in a couple of years back. These can detect when you relieve yourself, remove the waste with suction and clean you up after each use. They can even eliminate unpleasant sounds and odors.

Unfortunately, the wearable toilet project won’t be completed for another five years—but I can see a market for this outside of the space program. It’s perfect for the incontinent, elderly and just plain lazy. [Yomiuri via Pink Tentacle]

NASA taps Orbital Sciences, SpaceX for ISS resupply missions

The firms not mentioned here are just as important as the ones that are, as the privatization of space has just inched closer to reality. Rather than NASA handling ISS resupply chores itself or farming the job out to mega-corps such as Lockheed Martin or Boeing, the agency has instead awarded one contract each to Virginia-based Orbital Sciences (valued at around $1.9 billion) and California’s own SpaceX ($1.6 billion). The two will be responsible for 20 service flights between 2009 and 2016, with each trip requiring delivery of “a minimum of 20 metric tons of upmass cargo to the space station.” The agreements also call for “delivery of non-standard services in support of the cargo resupply, including analysis and special tasks as the government determines are necessary.” So yeah, if FedEx / UPS have been balking at your request to ship to a Martian eBay winner, you now know who to call.
