NASA risks then saves lives of dummies in helicopters with external airbags

Airbags have evolved from being in cars to on cars, so it’s only natural that airbags in aircraft should be making the trip outside. NASA’s Subsonic Rotary Wing Project is attempting to make autorotation landings a little bit softer by slapping a pair of expandable kevlar cushions between the skids, and the first test was a success. The helo was dropped at a height of 35 feet, achieving a speed of 48 feet-per-second before unceremoniously hitting concrete. The helicopter and its simulant occupants were said to be largely undamaged, giving hope that such a system could reduce injuries — if you’re not traveling downward at more than 48 feet per second, anyway. Future tests are said to be coming in the next year and, if all goes well, we hope to be seeing these on real whirlybirds soon.

Stuck Mars Rover Moves!

NASA_Mars_Rover_Stuck_2.jpgNASA’s Mars rover Spirit, which has been stuck in deep Martian sand since April, has finally taken a (tiny) step forward, Space.com reports.

After an unsuccessful first attempt last week, the rover moved about half an inch forward, 0.3 inches to the left, and about 0.2 inches down. That’s barely anything–especially when you consider that engineers sent commands for Spirit to spin its wheels enough to drive 8.2 feet for that little bit of movement to happen.

But the good news is the left front wheel showed signs of climbing, even though the center of the rover moved downward slightly. And the non-functioning right wheel–which has been broken for a while now–had some forward push motion. Anyone besides me have their fingers crossed?

Worlds Largest Network Radio Telescope Powers Up

VLBA_Radio_Telescope.jpg

If one telescope is good, 35 is most assuredly better. That’s the number of networked radio telescopes that just powered up to observe 243 quasars across the universe, according to Space.com.

The goal, in what amounts to a record-breaking effort: “improve the precision of the reference time frame that today’s scientists use to measure positions in the sky,” as well as possibly enhance future Earth-based GPS systems.

Quasars emit powerful radio waves, and are distant enough to appear stationary as seen from our planet, the report said. Scientists will combine data using a technique called very long baseline interferometry (VLBI) to measure celestial positions. (Image credit: U.S. Navy/Naval Oceanography Portal)

NASA Astronauts Get Ready for Spacewalk

NASA_STS129_Cargo_Move.jpgTwo astronauts will leave the International Space Station and step into free space today, for the first of three spacewalks to deliver spare parts, Space.com reports.

The two spacewalkers will spend about six and a half hours floating outside. Here’s the to-do list: install a spare communications antenna for backup, grease the station’s robotic arm and rail car attachment point, and install new cables and a handrail for a future ISS expansion mission.

The shuttle Atlantis launched mission STS-129 Monday and arrived at the ISS Wednesday with a total of six crewmembers. The entire round trip will last 11 days, barring unforeseen weather issues the day of landing. (Image credit: NASA TV)

Lunar Water Discovery Fuels Colonization Dreams

NASA_Moon_Water_Rendering.jpg

NASA’s announcement on Friday that the LCROSS moon probe discovered significant water ice at the lunar south pole is fueling colonization hopes, Space.com reports. The idea is that someday humans could either colonize the moon, exploit it as a source of minerals, or use it as a launch pad to stage further space missions unhindered by Earth’s atmosphere.

For now, scientists are just concentrating on where they can find more than the equivalent of a dozen 2-gallon buckets of ice water already found, the report said. But in turn, it’s leading to a private moon race similar to the existing one for reusable spacecraft.

NASA to Attempt to Free Stuck Mars Rover

NASA_JPL_Mars_Rover_Earth.jpg

After several months of deliberation and research–much of which looked fun, at least from here–NASA will begin transmitting commands to its Spirit Mars Rover in an attempt to free the five-year-old robot from its Martian sand trap.

The rover has been stuck since April 23rd; engineers are expecting the process to take a while, and no one is sure if they will be able to free Spirit for good.

“This is going to be a lengthy process, and there’s a high probability attempts to free Spirit will not be successful” said Doug McCuistion, director of the Mars Exploration Program at NASA Headquarters in Washington, in a statement. “After the first few weeks of attempts, we’re not likely to know whether Spirit will be able to free itself.”

NASA researchers will transmit some commands, and then evaluate the results the next day as the rover sends back data. From there, researchers will make adjustments, and then keep going with more commands. Here’s hoping.

NASA turns iPhone into chemical sensor, can an App Store rejection be far away?

NASA turnes iPhone into chemical sensor, can an App Store rejection be far away?

People have been trying to turn cellphones into medical and atmospheric scanners for some time now, but when it’s NASA stepping up to the plate with a little device to monitor trace amounts of chemicals in the air, it’s hard to not start thinking we might finally have a use for all those tricorder ringtones. Developed by a team of researchers at the Ames Research Center led by Jing Li, the device is a small chip that plugs into the bottom of an iPhone and uses 16 nanosensors to detect the concentration of gasses like ammonia, chlorine, and methane. To what purpose exactly this device will serve and why the relatively closed iPhone was chosen as a development platform are mysteries we’re simply not capable of answering. Damn it, man, we’re bloggers not scientists!

Update: George Yu, a developer who wrote this implementation for Jing Li, commented to let us know that the choice to go with the iPhone was made because it was “cool,” but he soon realized that choice was a “horrible mistake.” We’re guessing that could have something to do with an apparent lack of wireless coverage at Ames if the above screenshot is anything to go by.

LaserMotive finally wins NASA’s Elevator:2010 Beam Power Challenge, climbs at 3.9 meters/second (video)

LaserMotive finally wins NASA's Space Elevator:2010 Beam Power Challenge, climbs at 3.9 meters/second

NASA has been trying to find someone that could meet its rigorous Space Elevator demands since 2005 and, after some notable failures, we finally have a winner. A company called LaserMotive has won the Beam Power Challenge, tasked with creating a laser-powered robot able to lift a weight on a cable at a speed of greater than two meters per second. LaserMotive’s bot nearly doubled that, managing 3.9 meters per second in one test. It was the only competitor to beat the requirement, meaning it gets the full $900,000 prize, and if anyone ever gets around to winning the Tether Challenge we might just be able to get somewhere. Nausea-inducing test video is embedded below.

Lunar Lander Prize of $1 Million Still Up for Grabs

NASA_X_PRIZE_Lunar.jpg

The $1 million race to build a lunar lander is heating up, as–unexpectedly–Masten Space Systems’ Xoie rocket prototype has taken the lead. MSNBC reports that the Masten team’s remote-controlled rocket had a successful test flight, just one day after a damaging fire on the launch pad and two days after communications glitches derailed two earlier launch attempts.

Level 2 of the Northrop Grumman Lunar Lander Challenge requires that a remote-controlled aircraft makes a complete round trip between one launch pad and a boulder-strewn pad about 164 feet away, according to the report. Each leg of the flight needs to last at least three minutes, and the rocket has to rise up 50 meters from the ground–all within a 135 minute time period.

Armadillo Aerospace–backed by id software’s John Carmack–first qualified to win last month. Since more than one team has now qualified for the prize, judges will decide who to award it to based on the accuracy of the flight. (Via Slashdot)

An Astronaut Explains How We’ll Fall In Love With Space Again

Our friend and astronaut blogger Leroy Chiao sat on the human spaceflight advisory committee which released its report last week. Since news stories about it were hazy at best, we asked him to explain what it really said:

It is not surprising, but it is dispiriting, to realize how little the general public knows (or cares?) about space exploration. We seem to take for granted, that America is the leader in human spaceflight. Will it always be so?

Remember high school history? Remember Portugal? They dominated the seas way back when, and thus, dominated the known world. Then what happened? Did they get lazy? Rest on their laurels? Sure, they still are the only ones who make port wine (at least any that’s worth anything), but WTF, over? How about Rome? Ok, maybe they just got too decadent. I never did see the X-rated movie Caligula, but it probably wasn’t too far off the mark. They got too full of themselves, and that was that.

So, what’s it going to take to get America enthralled again about space exploration? This was one of the questions we considered, on the Review of US Human Spaceflight Plans Committee, also known as the Augustine Committee, after our chairman, respected aerospace veteran, Norm Augustine. What do we have to do? Do we have to go chase imaginary aliens to get your attention?

The media generally missed the mark on understanding our report. How is this possible? Maybe I’m too close to it. I suppose I shouldn’t over-think this. I should give ‘em what they want. Alright then, here are the report highlights, from my perspective:

• The space program needs more money. NASA has been trying to do too much with too little for too long. Let’s either spend more money, or scale back our expectations.

• The Space Shuttle has been a magnificent, beautiful flying machine, but it is more fragile than we thought, and it is too expensive to operate. There is a case to be made to keep flying the Shuttle for a few more years, but only if we are going to base the next heavy launch vehicle on its technology.

• The International Space Station has been a great success, in that an international framework for cooperation has evolved. This is the future, not only in space exploration. In addition, there have been relevant, significant scientific results from research conducted onboard. The US should use this framework, to move exploration forward beyond Low Earth Orbit (LEO).

• The Constellation Program was a reasonable path, five years ago, when the Vision for Space Exploration was first formulated. Since then, budget shortfalls have caused significant delays. Moreover, the goals evolved into a focus on getting astronauts back to the Moon, to the development of the Ares family of rockets and the Orion spacecraft. The public generally is bored with going back to the Moon, since we already did this forty years ago.

• Commercial crew access to LEO should be considered. Traditional aerospace companies can do this, and who knows? Maybe the startups can too, more efficiently. At any rate, the technology has existed for almost fifty years, it’s time to give it a try.

• Heavy Lift Vehicle: Let’s choose one, then, do it. Be it Ares-V, Ares-V Lite, Evolved Expendable Launch Vehicle, or Shuttle Derived. Pick one.

Clear as mud? For a more detailed (yet, still very high-level) explanation, check out my blog.

Leroy Chiao, Ph.D. served as a NASA astronaut from 1990-2005. During his 15-year career, he flew four missions into space, three times on Space Shuttles and once as the copilot of a Russian Soyuz spacecraft to the International Space Station. On that flight, he served as the commander of Expedition 10, a six and a half month mission. Dr. Chiao has performed six spacewalks, in both US and Russian spacesuits, and has logged nearly 230 days in space.

Dr. Chiao is Gizmodo’s official astronaut (and “astroblogger“). On occasion, he still ponders strategies to hunt for imaginary aliens.
