Food for Mars: A Daunting Challenge

MarsNews - Wed, 2010-07-28 18:43
Most people find the palatability of in-flight entrees an oxymoron. But even frequent fliers seldom encounter more than a few such meals per week. Astronauts, in contrast, may have to survive months in orbit dining on a really limited menu of processed foods and reconstituted beverages served from oh-so-glamorous plastic pouches. Luckily, even the International Space Station can restock its pantry several times a year because these foods are relatively perishable. Which explains the problem NASA faces in planning for really long missions -- like a trip to Mars. Astronaut foods may appear indestructible, but many crew favorites don't retain their nutrition or palatability for even a year, notes Michele Perchonok.

Meet Google’s Space Commander

MarsNews - Wed, 2010-07-28 17:46
Google, as you may know, runs a search engine and sells ads. How odd then that Tiffany Montague works at the company. Ms. Montague is the manager of Google’s space initiatives –- overseeing things like sending robots to the moon and ogling Mars. It’s not exactly the stuff that keeps the lights on at the Googleplex, but this type of work seems to make Sergey Brin and Larry Page happy. Unlike many Google employees, Ms. Montague is not an engineer by trade. Rather, she arrived at Google about five years ago, after serving as an officer for the Air Force and working at the National Reconnaissance Office. Ms. Montague’s specialty centered on flying high altitude aircraft and snooping on stuff.

Check It Out: Planetary Triangle Forming in the Evening Sky

MarsNews - Wed, 2010-07-28 17:44
A trio of planets converging in the night sky this week and for several nights will give casual skywatchers the perfect chance to easily see and identify worlds they might not normally notice. The event, building up to a super celestial snuggle in early August, is also a chance to watch and grasp orbital mechanics in action. Venus, Mars and Saturn will gradually, night after night, move into a tight triangular grouping in the early evening sky. (This graphic shows where to look to spot the planetary triangle on Aug. 5.)

What's Your Poison?

SETI - Mon, 2010-07-26 07:00

“Aspirin and Old Lace?” Okay, it would take a bottle full of pills in a glass of elderberry wine to really harm you, but aspirin can be deadly. So can too much of anything, including water. Dose is key in toxicology, after all, but there are some poisons that can do deadly work in tiny amounts.

Hear about the chemistry of poisons … why Botox may freeze your emotions as well as your face… which animal is most lethal to humans… and how 19th-century poisoners got away with murder – until the birth of forensic science.

Cosmic Soccer Balls

The World Cup may be over, but there are soccer balls still bouncing in space. Astronomers using NASA's Spitzer Space Telescope have discovered soccer-ball-shaped molecules, known as 'buckyballs.'

Mars sample return mission could begin in 2018

MarsNews - Tue, 2010-07-20 22:05
Space officials in the United States and Europe are planning an ambitious dual-rover mission that could start collecting Martian soil samples in 2018 to be picked up by a subsequent mission and returned to Earth in the 2020s. The costly mission would blast off on an Atlas 5 rocket in 2018 and land two rovers on Mars with a single "sky crane" descent system that will be tested for the first time at the Red Planet in August 2012. It would be the first time two rovers will be delivered to the same landing site on Mars. The European Space Agency's ExoMars rover and a $2 billion NASA Mars Astrobiology Explorer-Cacher mission are the leading candidates for the tandem project.

Video Camera Will Show Mars Rover's Touchdown

MarsNews - Tue, 2010-07-20 22:04
A downward-pointing camera on the front-left side of NASA's Curiosity rover will give adventure fans worldwide an unprecedented sense of riding a spacecraft to a landing on Mars. The Mars Descent Imager, or MARDI, will start recording high-resolution video about two minutes before landing in August 2012. Initial frames will glimpse the heat shield falling away from beneath the rover, revealing a swath of Martian terrain below illuminated in afternoon sunlight. The first scenes will cover ground several kilometers (a few miles) across. Successive images will close in and cover a smaller area each second. The full-color video will likely spin, then shake, as the Mars Science Laboratory mission's parachute, then its rocket-powered backpack, slow the rover's descent. The left-front wheel will pop into view when Curiosity extends its mobility and landing gear.

To Researchers, Space Samples Are Well Worth The Cost of Fetching

MarsNews - Tue, 2010-07-20 22:03
If a Japanese space capsule that recently returned to Earth is found to have collected particles from a billion-year-old space rock, it will join the short history of lucrative sample-return missions. Retrieving samples from space is considered more complicated, potentially more costly, and riskier than conducting remote or robotic expeditions, but successful retrievals can confirm or disprove theories more accurately and can fuel or accelerate decades of scientific research. As researchers and mission scientists await an analysis of what the plucky Hayabusa asteroid probe has brought back from space, they say previous sample-return missions have proven their usefulness. And, with improvements in technology and in methods of cleaning and sterilizing storage facilities, future missions to retrieve samples from Mars and beyond could provide even more valuable insights into the unknowns of our solar system.

Red Planet rover could emerge from slumber soon

MarsNews - Tue, 2010-07-20 22:01
NASA officials say the best chance to hear from the napping Spirit rover again will be in September or October, but the timing of the robot's revival from winter hibernation is an engineering guessing game. Spirit was forced to sleep by the cold winter in the Martian southern hemisphere, where low sun angles were not sufficient to power the rover through solar panels. The stranded rover last communicated with Earth on March 22. Spirit has been stuck in a sand pit known as Troy since April 2009, leaving the rover tilted away from the sun and limiting its ability to produce electricity. The winter solstice at Spirit's location was May 13, and conditions should now be improving. But the rover's batteries likely won't be collecting enough sunlight to begin communicating again until September or October.

Test Image by Mars Descent Imager

MarsNews - Tue, 2010-07-20 22:01
The Mars Descent Imager for NASA's Mars Science Laboratory took this image inside the Malin Space Science Systems clean room in San Diego, Calif., during calibration testing of the camera in June 2008. It shows the instrument's deputy principal investigator, Ken Edgett, holding a six-foot metal ruler that was used as a depth-of-field test target. The camera is focused at 7 meters (23 feet) so that everything between about 2 meters (7 feet) and infinity is in focus. This image shows a slightly out-of-focus rock (a rounded cobble of Icelandic basalt with tiny crystals and vesicles) at a distance of about 70 centimeters (2.3 feet), equivalent to the distance the camera will be from the ground after the rover has landed.

Dynamite Offers Warlord of Mars #1 for a Dollar

MarsNews - Tue, 2010-07-20 21:58
Comic Vine received a press release from Dynamite today letting us know that they’re launching WARLORD OF MARS in October for a dollar-priced first issue. The series, spinning out of Edgar Rice Burroughs’ classic pulp series, will be written by Arvid Nelson, drawn by Stephen Sadowski & Lui Antonio and covered by the likes of Alex Ross and J. Scott Campbell. The famous John Carter of Mars will be joining the impressive roster of heroes Dynamite's steadily assembled from the long, crisscrossing tradition of comics, pulp and literature. I’m talking about characters like the Green Hornet, the Lone Ranger, Zorro, the Phantom, Buck Rogers and Sherlock Holmes.

Planning a trip to Mars

MarsNews - Thu, 2010-07-15 23:58
The temperature's literally freezing, the air is poisonous and you'll die if you go outside without your space suit. Why would you put your hand up to be on the first space shuttle to Mars? Space tourism may not be a reality yet, but in preparation for the day that it is, Guy Murphy has written a book about living on the red planet, titled Mars: A Survival Guide. Murphy wouldn't say no to a seat on the shuttle but he accepts moving to a Martian neighbourhood would have its downsides. However those problems would pale in relation to what else the planet has to offer.
