Cities Built on Fertile Lands Affect Climate
Devar writes "While cities provide vital habitat for human beings to thrive, it appears U.S. cities have been built on the most fertile soils, lessening contributions of these lands to Earth's food web and human agriculture, according to a study by NASA researchers and others. Though cities account for just 3 percent of continental U.S. land area, the food and fiber that could be grown there rivals current production on all U.S. agricultural lands, which cover 29 percent of the country. Studies like this one may lead to smarter urban-growth strategies in the future." -
Russian Rovers on the Moon
An Ignorant American writes "Perusing an Air & Space magazine the other day, I came across an article about Russian Moon Rovers during the space-race era. Thanks to my American science education, I had never heard of this feat. I asked around (friends and coworkers) and nobody else I've talked to has heard of them either. They were called 'lunokhod', and were the first of their kind. Unmanned, remotely operated rovers with basic instrumentation. Two were successfully landed on the Moon, each driving for many miles on the Moon's surface, returning tens of thousands of pictures. You can do a Google Search to start your education, or read what they have to say at Wikipedia on the subject (Wikipedia also has some external links.)" -
A Deep Space Primer
phil reed writes "With the latest Mars missions still in the news, people might be curious about what it takes to actually run a deep space mission: how a spacecraft is designed, how the communications are handled, what kind of project management is in place to make it all work. The Jet Propulsion Laboratory has a primer online that gives broad general coverage of all aspects of putting a satellite into orbit and how to manage it once it's there. Fascinating reading, with lots of links to more detail." -

Second Hypersonic X43 Scramjet Ready for Testing
Dan writes "I am sure most of you remember how NASA was forced destroy their first hypersonic X43 seconds in it's maiden flight, which was a big setback for the american hypersonic scramjet program. Well NASA just finished one of the final tests and is preparing to launch it as early as February 21! I wish them the best." -
James Cameron's Illustrated Mars Reference Design
An anonymous reader writes "Terminator Director James Cameron commissioned renderings of the NASA Mars Reference Design [HTML, 4 PDFs]. The mission profile calls for a cargo ship sent ahead of a crew, a huge (Terminator-like?) rover, and inflatable habitats. It's not clear where Skynet and the T-800's hyper-alloy combat chassis fit in yet. Between now and then, the 5 Mars missions: 2005 Mars Reconnaisance Orbiter, 2007 Phoenix and Netlanders, 2009 Science Lab Rover, and 2011 Scout. Skynet comes in 2026." -

Mars Landers - Opportunity, Bedrock, Aerosmith?
Iphtashu Fitz writes "As was reported last week, the first Mars rover Spirit had some communications problems that the folks at the JPL have finally managed to trace to problems with its flash memory. Reuters is reporting that Opportunity seems to be having some power-related problems, too. It appears a faulty thermostat is turning a heater on overnight without being told to do so. While NASA isn't concerned about the rover overheating, they're exploring the long-term effects of continued power drain on the second rover." The article also notes: "The first three-dimensional, panoramic images beamed back from Opportunity showed an intriguing outcrop of exposed bedrock" - there's now a color version of the same image. Finally, lightwaveman points to the Spaceflight Now status page regarding new priorities for the Mars mission: "The airing of today's Mars rover news conference is being delayed on NASA TV to show the band Aerosmith touring International Space Station Mission Control at Houston's Johnson Space Center." -

A First Look At Meridiani Planum
loconet writes "After Opportunity 's successful landing on mars , NASA has recieved the first images showing the landing site revealing a surreal, dark landscape unlike any ever seen before on Mars. The terrain is darker than at any previous Mars landing site and has the first accessible bedrock outcropping ever seen on Mars. The outcropping immediately became a candidate target for the rover to visit and examine up close." -

Mars Rover Opportunity Lands Safely
JoeRobe writes "All indications are that the Mars Exploration Rover Opportunity has safely landed on Mars. After 10 minutes of bouncing and rolling, it has come to a rest and transmitted its signal. There are no fault tones, indicating that there were no errors during landing and rolling. The rover has landed in the Meridiani Planum, where there are large deposits of hematite, indicating the presence of past water. The lander has landed on one of its side petals, so the next step is to make itself upright and deflate its airbags." And loconet writes "Reuters and abc.net.au, among others, are of the first news sources to confirm that Opportunity has successfully landed on Mars. The probe had successfully made contact with controllers on Earth after landing at 0505 GMT on Sunday in an area of the planet known as the Meridiani Planum. The landing procedures achieved a best-case scenario on which all systems performed as expected. At first, engineers thought the lander had been rolling for a long time, but it turns out the antenna used to communicate with Earth was pointing towards the ground, which made the signal bounce off Mars and as the Earth moves, made it seem as if it had been bouncing for over 5 minutes. The lander is currently side petal down, and will take a while before it straightens itself out. California's governor Arnold Schwarzenegger and Ex Vice-president Al Gore were in attendance at the event in the JPL facilities." Many readers also wrote to point out the coverage at spaceflightnow. -

Spirit Sends Debug Information to Earth
gfilion writes "NASA has released a press release that says: 'Shortly before noon, controllers were surprised to receive a relay of data from Spirit via the Mars Odyssey orbiter. Spirit sent 73 megabits at a rate of 128 kilobits per second.'" They've been having communications troubles with Spirit since Wednesday, so it's good to hear from it again, even if the data is just filler. -
Mars Express Confirms Water on Mars
jki writes "So, finally: Through the initial mapping of the South polar cap on 18 January, OMEGA, the combined camera and infrared spectrometer, has already revealed the presence of water ice and carbon dioxide ice. This information was confirmed by the PFS, a new high-resolution spectrometer of unprecedented accuracy. The first PFS data also show that the carbon oxide distribution is different in the northern and southern hemispheres of Mars. The MaRS instrument, a sophisticated radio transmitter and receiver, emitted a first signal successfully on 21 January that was received on Earth through a 70- metre antenna in Australia after it was reflected and scattered from the surface of Mars. This new measurement technique allows the detection of the chemical composition of the Mars atmosphere, ionosphere and surface." On another note, NASA has gotten some sort of signal from Spirit, but it's still not fully functional. -

Spirit Rover Communications Error

The Dirt On Mars, In Words And Pictures
An anonymous reader writes "The Spirit rover's first soil analysis reveals some puzzling features about Gusev crater. The region seems to contain the greenish silicate mineral, olivine, which usually is considered water-reactive and thus volcanic in origin. For olivine to be found in the soil may point to rock formation during a drier period in martian history, even with strong evidence for sampling in an ancient lakebed. A second puzzle is why the soil seems so crusty. After the rover arm pressed soil down, the top layer of dust hardly moved, a finding that suggests something may be binding the dust like some type of salt or thin cement." For even more and better Mars pictures, read on below.mlyle writes "I've spent a few hours hacking together some software to deal with the Mars Exploration Rover imagery at JPL. The software puts together a webpage and RDF feed of new raw imagery as it is posted to the JPL site, along with technical information decoded about how the picture was taken. It also produces stereo anaglyphs and color images that NASA has not seen fit to convert and make publically available. Be sure to also check out the ultra high resolution image of the lander as viewed from Spirit."

Space Tug to Save the Hubble?
Aglassis writes "In an article at SpaceRef, the CTO of Orbital Recovery Corporation claims that his company will be able to develop a space tug that could save the Hubble Space Telescope (from becoming 'a ballisticly implanted reef in the Pacific') by either moving it into a much higher stable orbit, or by moving it to the ISS where it could be maintained and operated. Some of the reasons that he cites are that the Hubble's replacement, the James Webb Space Telescope, could be delayed or suffer some sort of failure. Since the JWST will be at the L2 point, servicing will be impossible." -

USA To Return To Moon By 2015, Then Mars
securitas writes "This afternoon George Bush announced space exploration plans for the USA to return to the Moon by 2015, the design and construction of a new space vehicle fleet by 2014 (called the Crew Exploration Vehicle) to replace the aging space shuttles which will be retired in 2010, and the construction of a permanent Moon base, followed by manned missions to Mars. The initiative begins with a $1 billion increase to NASA's budget and $12 billion in new space exploration money over next five years. However Congress is concerned about how to pay for the new space policy initiative in the face of a $500 billion national budget deficit. AP via Yahoo has a Moon/Mars/space policy FAQ, and there's more at NASA and the New York Times among others." -
Mars Rover Rolls And Turns
hcg50a writes "MSNBC reports that overnight, 'the golfcart-sized rover cut the final cord tying it to the landing platform that it came in on 10 days ago, then backed up about 10 inches (25 centimeters) and turned 45 degrees. These were the first maneuvers planned in preparation for having Spirit roll 10 feet (3 meters) down a ramp onto the Martian surface on Wednesday night or early Thursday morning.' The NASA Mars rover website has complete animations from numerous cameras of the 45-degree turn. Driver training was never this cool!" -

One wonders why these literal rocket scientists didn't just get a software programmable Linux or PalmOS based wrist-computer and hack together a Mars-time display application into it?" -
Can Manned Spaceflight Save the Economy?
Barry asks: "Driving home last night I was listening to a particularly goofy AM talk station. Just before the syndicated UFO talk show 'Strange Days... Indeed' came on, the discussion turned to the Mars Rovers and George Bush's newfound love of space exploration. The interesting thought was that a large number of American political leaders were about to join Bush in endorsing a new manned space program because it would generate 'millions of jobs'. Given that manufacturing jobs are being shipped offshore, and high tech jobs are following, this almost made sense. A primarily unemployed population could mean big trouble. So I am wondering how many people were employed during the height of NASA's glory days, and what kind of economic impact would we expect if a similar program - a Mars mission for example - were launched today?" -
Inner Workings of High-Gain Mars Rover Antennas?
cavac asks: "I've been searching for detailed info on how the high gain antennas on the Mars Rovers work, but did not find much useful information except that they DO work. I've been wondering: they are disc-shaped and are approximately the size of a CD. They somehow reassemble parabolic antennas but actually aren't, are they? Anyway, how much use would a parabolic antenna that size have? When I first saw them, they reminded me of the old antennas[*] (enclosed in plastic) used on vacuum tube based radio projects[*]. So, what's really inside the Mars Rovers high gain antennas? Note: Links marked with [*] are german language but the pictures should be self explaining."
