"'An automated rendezvous does all sorts of things for your missile accuracy and anti-satellite programs,' said John Sheldon, a visiting professor of advanced air and space studies at Maxwell Air Force Base in Alabama. 'The manned effort is about prestige, but it’s also a good way of testing technologies that have defense applications.'" In order to keep pace with the increasingly proficient Chinese space program, President-elect Obama may be considering retying NASA to the Pentagon, "because military rockets may be cheaper and ready sooner than the space agency’s planned launch vehicle, which isn’t slated to fly until 2015...Obama has said the Pentagon’s space program -- which spent about $22 billion in fiscal year 2008, almost a third more than NASA’s budget -- could be tapped to speed the civilian agency toward its goals as the recession pressures federal spending."

Hmm. On one hand, I would think making NASA yet another fiefdom of the Pentagon would greatly facilitate its ability to lock down the funding it needs for various exploratory endeavors, recession or no. And if the types of conveyance vehicles NASA needs are basically sitting around gathering dust in some Pentagon-owned warehouse next to the ark of the covenant, well then it only makes sense to combine the two programs. No need to reinvent the, uh, rocket.

On the other hand, putting the brass in charge is probably going to have deleterious effects on the types of projects NASA pursues in the future. And, in a perfect world, there's something to be said for having a civilian space program completely outside the purview of the military. In fact, now that i think about it, won't combining the Pentagon and NASA space programs cut back on the types of international cooperation that have guided our efforts in space in recent years? GIven the current economic climate, I guess this is the best way for NASA to continue pursuing its goals in the short term. Still, there could well be trouble ahead.

"The last Twitter post said it all: "01010100 01110010 01101001 01110101 01101101 01110000 01101000."" Or, in other words, Ground Control to Phoenix Lander: You've really made the grade. Having seemingly succumbed to the Martian winter at last, the Mars Phoenix Lander is pronounced deceased by NASA. "NASA official Doug McCuistion counseled people to view Phoenix’s end as 'an Irish wake rather than a funeral. It’s certainly been a grand adventure.'...While some followers said farewell to Phoenix in computer language today, others kept it simple. 'Good bye Phoenix, I love you :(,' said user patach."

Europa, Enceladus...Titan? The ESA's Cassini-Huygens probe discovers a liquid lake on Saturn's largest moon, although it's definitely not water. ""Detection of liquid ethane in Ontario Lacus confirms a long-held idea that lakes and seas filled with methane and ethane exist on Titan." [Via Quiddity.]

"Fact:...The density of Saturn is so low that if you were to put it in a giant glass of water it would float." And another pilfered link, which I meant to post last week: Megg of Quiddity points the way to 10 Cool Facts about Space (although, to paraphrase The Smiths, some facts are cooler than others.)

NASA prepares a probe, named Phoenix, to dig for water on Mars. "Upon reaching Mars in May 2008, the spacecraft is to land just as the winter ice begins to recede around the polar cap."

In "world of the future" news, NASA announces it plans to establish a permanently-staffed base camp on the moon by 2024, preferably at one of its poles. (Here's the rationale.) A moonbase within 18 years? I'm all for it...just keep an eye out for monoliths and make sure Sean Connery runs a tight ship.

If you believe they put "a" man on the moon, then there's nothing up my sleeve, and nothing is cool. Also, you'll have no problem with the recent update to Neil Armstrong's famous first words there. Score one for the lunar grammarians.

Sorry, Virginia (and all the other kids out there who just memorized the solar system): As the dust dies down at the recent astronomer's conference, word comes to light that Pluto has in fact been demoted to "dwarf planet," a status it'll hold with UB313 (Xena) and Ceres.

At a meeting of 2,500 astronomers in Prague to determine the appropriate definition of "planet" (in part due to the Xena challenge), it appears Pluto might soon be reclassified as a "dwarf planet" (as opposed to a "terrestrial planet" (Earth, Mars) or a "gas giant planet." (Jupiter, Saturn)) rather than fully being demoted to non-planet status. Said one proponent of the plan: "I think we have done something that will make the Plutocrats and the children of the United States happy."

"'We certainly have not convinced the community, and that's been a little bit disappointing,' said David McKay, a NASA biochemist and leader of the team that started the scientific episode." Ten years later, CNN summarizes the simmering scientific dispute over a Martian meteorite, and the possible (albeit now seemingly quite unlikely) signs of life within.

The European Space Agency releases the first new pics from their recent "Express" mission to Venus. The Venus Express probe entered Venusian orbit on Tuesday.

After discovering a disk of gas, dust, and rubble orbiting a pulsar, astronomers believe they've figured out how planets are made. "It shows that planet formation is really ubiquitous in the universe. It's a very robust process and can happen in all sorts of unexpected environments."

"'The idea is to look at Mars and not think of it as a mysterious alien place,' Christensen said." Along the lines of Google Moon, one can now journey to Google Mars.

"I think that this mission will re-write the science books on Mars." More happy space news following the discovery of water on Enceladus: NASA successfully pilots the Mars Reconnaissance Orbiter into Martian orbit. "It was picture perfect. We could not have planned it any better." (Phew...looks like everyone successfully converted to metric this time.)

"All these worlds are yours, except Europa...oh, and Enceladus." In very big news, NASA announces that Cassini has found water plumes on Enceladus, Saturn's moon. "This finding has substantially broadened the range of environments in the solar system that might support living organisms, and it doesn't get any more significant than that...I'd say we've just hit the ball right out of the park." What's more, "unlike Europa, which researchers believe harbors a vast ocean beneath kilometers of thick ice, Enceladus' water may be just below the surface."

More James Cameron news: Harry of AICN has a wide-ranging conversation with the director which, if you can get past the usual Knowlesisms, reveals that Project 880 is in fact Avatar, and that Cameron has been working with NASA on a "Live Video Stereo Motion Image" (3-D) camera for the next Mars Rover.

The LA Times examines the beginnings of the second lunar space race, which will involve, among others, the US, Europe, China, and India. "Some researchers even have a name for the first lunar city: Jamestown, in honor of the first English settlement in the New World."

I've been extremely derelict in my space coverage around here lately. So, as a quick catch-up: Welcome back, Stardust, and Godspeed, New Horizons.

"To become a multiplanet species, we must master the skills of extracting local resources, build our capability to journey and explore in hostile regions, and create new reservoirs of human culture and experience. That long journey begins on the moon -- the staging ground, supply station and classroom for our voyage into the universe." Astrophysicist Paul Sputig eloquently makes the case for a return to manned lunar exploration.

"Suppose the asteroid is traveling 60,000 miles per hour. You want to make it 60,001." Concerned by the possible 2036 impact of 99942 Apophis, two clever NASA astronauts have developed a tractor beam of sorts to pull asteroids off a possible collision course. Namely, send a relatively small (20-ton) ion-powered spacecraft to intercept and hover near the offending asteroid, and then let gravity work its mojo. "Even as the spacecraft counters the asteroid's gravity, he said, its own gravity will pull the asteroid out of orbit."
