NASA Creating Meals for Mars Mission to Last Five Years

Eating five-year-old food doesn't sound too appetizing to us. But to the astronauts that NASA will eventually send to Mars, it'll taste as good as any five-star restaurant's fare. Well, maybe not that good, but it will be the sole sustenance for that group of men and women during their grueling trip into outer space.

According to the Los Angeles Times, NASA will need to pack enough food to feed six people every day for three years. That's about 6,750 breakfasts, lunches, snacks, and dinners. The toughest part is making sure the food doesn't spoil. NASA engineers are searching for different preservation methods and menus for the trip, which would last years. Their plan will most likely involve sending food to Mars ahead of the astronauts.

Sixth-Grader Names Next Mars Rover


"Hey, Mom and Dad, guess what I did today? I named NASA's newest Mars rover. Let's get ice cream."

We're guessing that's the conversation 12-year-old Clara Ma had with her parents after the sixth-grade student from Sunflower Elementary School in Lenexa, Kansas won a nationwide contest to name the next Martian rover. Her contest-winning appellation? Curiosity.

NASA has a history of naming its devices by public polling; indeed, back in the mid-'70s, the first space shuttle -- initially called 'Constitution' -- was named 'Enterprise' after Captain Kirk's fictional ship from 'Star Trek,' following a large write-in contest. More recently, the space agency was forced to exercise its seldom-used editorial powers when thousands of people voted to name the newest module of the International Space Station the 'Colbert' for comedian and talk-show host Stephen Colbert, who had urged his viewers to write his name onto the ballot.

Spaceship 'Force Field' Could Protect Astronauts on Trip to Mars


While there's certainly no shortage of folks working on sending robots to Mars, there's also thankfully a few researchers focusing on making the trip a bit more bearable (and survivable) for us humans, and a group from a consortium of different institutions now say they've made some real progress on that front. Their idea is to use a portable "mini-magnetosphere," which would protect a spacecraft from harmful solar storms and cosmic rays in much the same way the Earth's magnetosphere naturally protects the planet.

That is actually an idea that has been around for decades, and was shown last year to be at least theoretically possible, but it has only now been taken beyond the realm of computer simulations. That was apparently possible thanks to the use of an unspecified "
apparatus originally built to work on fusion," which allowed researchers to recreate "a tiny piece of the Solar Wind" and confirm that a small "hole" in the wind would indeed be all that would d be necessary to keep astronauts safe.

Of course, the leap from the lab to an actual spacecraft is another matter entirely, but the researchers seem to think that there's quite a bit of promise in the idea.

Mars Probe Hampered By Radio Glitch


The first thing the news Mars lander Phoenix wanted to do when it reached the red planet was stretch its arm. (What do you typically do after a long flight?)

This first step was hampered, though, by a radio communications glitch that delayed its activity for most of Tuesday. The glitch, however, was aboard the Reconnaissance, the Mars orbiter responsible for relaying data between the planet surface and mission control here on cozy planet Earth. The extremely smart folks at NASA's Jet Propulsion Lab who head up the Mars lander program say the radio on the orbiter likely switched its radio off due to a cosmic ray.

Even though the glitch has been fixed, a second orbiter, the Odyssey, will be used for now to relay information to Phoenix. The lander has settled on a promising patch of Martian soil that looks like it may contain ice about one foot below the surface, which could mean evidence of life. The arm will be used to start digging the surface to collect samples for analysis.

The effort to explore Mars has been hampered by unexpected glitches before. A major computer malfunction severely hampered the abilities of the polar lander in 1999. Another craft intended to study Mars' atmosphere wasn't properly calibrated, which caused it to burn up as it approached the Red Planet. [Source: CNN]

Mars Phoenix Lander Makes Near-Perfect Landing


Things are looking good for the Phoenix lander which touched down on Mars at 4:53pm on Sunday, May 25. The NASA nerds are reporting an almost perfect landing, with the spacebot tilted only one quarter of a degree. In fact, they're claiming that this landing was "far smoother than any simulation or test that was ever done." The lander's north-pole location is measured at -106 degrees Fahrenheit and chock-full of life-preserving ice. Phoenix will chill on Mars for 90 days, sniffing soil and looking for frozen Martians in whatever form they may take. Now that Mars Oddyssey -- one of its main communication uplinks -- has passed over the lander, we have our first pictures, one of which is above. Nice work, guys!

Robot Rock Climbers Headed for Mars


We've reported on robots that fly, robots that spy, robots that teach, and even robots that kill. But, robots that are designed specifically for mountain climbing are a little new to us, so with that we bring you video of two robots designed specifically for the task of scaling sheer cliff walls.

The first -- Capuchin --is a research bot, an evolution of earlier climbing bots created at Stanford University. This new bot is much faster than the old and is more capable of shifting its weight from leg to leg to maintain its balance. Also shown in the video is a similar robot from Dennis Hong at Virginia Tech, one that looks to scamper a little more quickly but with the help of a tether. Hong's bot will eventually have a laser range finder mounted on it, enabling it to scan and plot its course as it climbs. Current climbing bots all rely on pre-plotted maps to chart a course upward.

The goal driving many of these researchers is someday seeing their bots shuttled off to Mars and deployed to climb some of the many cliffs found on the planet, some of which measure multiple miles in height.

That's one task we're happy to leave to a machine.

Rover Video of Mars "Dust Devil"



You've probably seen dust devils swirling about on a windy day. They're basically mini-tornadoes that form when turbulent air sucks up some dust or snow or other debris into a column. Usually they're only a few feet high, but sometimes they can be much, much larger.

On Mars, apparently, they can apparently be several kilometers high, as attested by the above image captured by Spirit, one of the Mars Rovers. The animation (based on a series of pictures and available in a larger version here) shows a dust devil travelling from left to right across the Martian landscape. The surface there is so dusty that these columns of air are particularly noticeable, even from sattelite images as shown in this NASA article on the subject.

This is a graphic display that Mars does indeed have an atmosphere, and a strong one at that, despite having less than one percent of the pressure of our atmosphere here on earth.

The footage is a few months old, but we're huge Mars nuts and haven't seen it yet. If anybody's got any other similar clips or links to similar videos, let us know below.

What It Will Be Like To Land On Mars

Mars Landing Site
Landing on another world seems like an equally exhilarating and terrifying proposition. Exactly 38 years ago today, Neil Armstrong and Buzz Aldrin were probably shaking in their space boots saying to themselves "I hope this works," as they descended to the surface of the moon.

Well if an article in Universe Today is to be believed, landing on Mars may be an even more terrifying endeavor. It seems these pesky things called the laws of physics prevent touching down on the red planet from being as straightforward as landing on Earth or even the Moon.

The airbag method used for deploying unmanned probes won't work since we'll probably want our astronauts to avoid death or maiming. The Martian atmosphere is too thin for parachutes or aerobrakes to be effective with such a heavy payload, and the gravity on our sister planet is too strong for a powered descent like that used on the aforementioned Apollo missions.

The best bet so far is to use an inflatable donut with a skin stretched across it in a conical shape that will slow the landing craft from Mach 4 or 5 to Mach 1.
