Scientists use lasers to find out why astronauts have bad skin
A team of German scientists are employing advanced imaging technology to help understand one of the unusual effects of long-term space habitation — thinning skin. Led by Professor Karsten Koenig of Saarland University, the study is an offshoot of the European Space Agency's Skin B project detailing the effects of skin aging in space. According to Reuters, his team has documented three astronauts, scanning their skin cells before and after their time on the ISS using multiphoton tomography (MPT). Koenig's company JenLab, the developer of the system, claims that its femtosecond laser pulses provide a "spatial resolution a thousand times higher than that of ultrasonic devices." It also eliminates the need for lengthy biopsy processes, instead serving up results in seconds.
NASA: nobody's going to Mars without our help
NASA's top priority is still taking humans to Mars, and it says private companies who want to do the same don't stand a chance without its support. Administrator Charles Bolden told a US House budget committee, "our ultimate focus is the journey to Mars and everything comes back to that," adding that the agency still plans to land there by the 2030s. A manned mission to Mars is crucial because the red planet was likely habitable in the past, and scientists must find out what went wrong to prevent a similar disaster on Earth. Bolden went so far as to say that humans need to "get away from being Earth-reliant... (and) Mars is the planet that is the most like Earth."
NASA InSight tapped for Mars drilling mission in 2016
The surface of Mars? Psh... been there. With the Curiosity stage well under way, our exploration of the Red Planet is about to take a dive beneath the dust. Interior Exploration using Seismic Investigations, Geodesy and Heat Transport -- InSight, for short -- was just confirmed as a new NASA mission, with the space agency set to launch in March of 2016. Based on the Phoenix lander, the craft is tasked with giving us a peek beneath the planet's surface, armed with tools that include a geodetic instrument from the Jet Propulsion Laboratory, which will be used to calculate Mars' rotation axis, a seismic wave sensor and a subsurface heat probe, to measure the planet's internal temperature. The program has a $425 million budget -- a bit shy of the $2.5 billion allocated for Curiosity -- not including the costly launch vehicle. NASA Administrator Charles Bolden said that InSight will help pave the way for future human missions to Mars, and represents just one of the related projects to come. Hit up the source link below for a closer look at JPL's latest endeavor.
Curiosity landing video assembled from high-res images (video)
A new video has been compiled by Spaceflight101.com showing Curiosity's final minutes of terror in glorious HD (though a dearth of frames and lack of stabilization make it a bit herky-jerky). It's an assembly of all the high-res photos taken by the buggy on the way down to its now familiar perch, rolling at the not-exactly-HFR speed of 4 fps, but still trumping a previous low-res thumbnail version. It gives a much clearer, rover's-eye-view of the journey, starting with the heat shield ejection and finishing with the dusty, butterfly-like touchdown. Check it out below the break to see the precarious descent -- and don't forget your Dramamine. Update: An enterprising (and patient) individual, Dominic Muller, spent four straight days creating a frame interpolated version of the video, giving the choppy footage a beautiful, smooth new look. Check out his version below the original after the break -- blow it up to full screen HD, crank the sound and enjoy.
Life on Mars: One week of Curiosity
Is there life on Mars? NASA's latest mission to the red planet might well answer that question, or perhaps the more pertinent question, was there life on Mars. At 10:02 AM EST on November 26th last year, the space agency's Mars Science Laboratory (to give the mission its full name) set off on its eight-month journey to the red planet. The most advanced equipment ever sent to the planet -- and the biggest-ever rover -- should allow exploration of some of the most interesting regions, over far larger distances than ever previously covered. On arrival, after negotiating a tricky landing, the mobile laboratory (that's Curiosity) will spend a Martian year (687 Earth days) analyzing rock samples and seeking evidence of conditions suitable for microbial life or -- we can live in hope -- actual evidence of the same. After the break, we take a look at some of the key events over the first seven days on the planet's surface.
NASA abandons Mars rover Spirit, chooses to remember the good times
More than a year after it first lost contact with its Mars rover Spirit, NASA has finally decided to throw in the towel. Yesterday, the agency confirmed that it will end all planned communications with the robot on May 25th, effectively ending the craft's seven-year mission. NASA was hoping that the approaching Martian spring would allow the Spirit to recharge its solar panels and re-establish radio contact, but it now appears that the craft sustained irreparable damage last winter, when it was forced to endure brutally cold temperatures. NASA executive David Lavery, however, says the rover team will remember the Spirit more for its achievements than its slow demise: "I think we'll all sit around and have a sip of Guinness and reminisce about when Spirit was a wee small little rover and look back at the accomplishments and successes rover had over its entire lifetime." So the Spirit's spirit will live on, but what about NASA's mission to Mars? Well, the Opportunity is still in good health and, later this year, will be joined by the next-generation, nuclear-powered rover Curiosity, which will investigate whether or not Mars ever supported life forms. Meanwhile, NASA's network of orbiting spacecraft will continue to passively listen for signals from the Spirit, just in case it miraculously comes back to life. Full PR after the break.
