Jupiters Great Red Spot Shrinking: Report

NASA_JPL_Jupiter_GRS.jpg

Notice anything different about Jupiter in your telescope lately? Astronomers have observed that one of Jupiter’s most recognizable features, the Great Red Spot, has been shrinking since the mid 1990s, according to CNN. The Great Red Spot is actually a giant, persistent, seemingly eternal storm that’s about the same size across as three complete Earths. But astronomers have noted that since 1996, the spot has lost about 15 percent of its size.

Xylar Asay-Davis, a postdoctoral researcher who was part of the study, said in the article that it measures up to a shrinkage of about one kilometer (about 0.6 miles) per day during that time period. While the shrinking size of the GRS isn’t news, the report said that
this research focused on the motion of the storm–which produced much
more reliable measurements.

NASAs Mission Madness Down to a Surprising Final Four

Mission-Madness-Final-Four.JPG

Even as basketball fans gear up for a weekend of NCAA semifinal action, NASA’s roster of 64 candidates for its “Greatest Mission of All Time” has been pared down to its own Final Four, and the remaining field is surprising, to say the least. Gone are heavyweights such as Apollo 11, the Hubble Space Telescope, Voyager I and II, Cassini, the Viking Mars landers as well as Spirit and Opportunity, still roving Mars after 5 years.

The remaining missions include LRO (the Lunar Reconnaissance Orbiter), SPB (that’s Super Pressure Balloon, for the uninitiated), the New Horizons mission to Pluto, and SOHO (the Solar and Heliospheric Observatory. The semifinals, for which the two-day voting period began today, pit New Horizons against SPB, which so far has been the Cinderella mission of this tourney, while the venerable SOHO faces LRO.

Mars Lander Helps Discover Hospitable Areas

We’re probably still a bit short of packing our bags and heading to Mars. But it appears NASA’s Phoenix Mars Lander may have helped scientists figure out which parts of the planet are more habitable for humans than others. Recent (and controversial) evidence that certain portions of the Mars landscape could host liquid water has lent credence to the theory that the planet contains the ingredients necessary to support life as we know it, Space.com reports.

According to the article, four papers are
under review for scientific publication on four major discoveries from the
mission, said Peter Smith, the Phoenix mission’s principal investigator at the
University of Arizona in Tucson. Under discussion are the following factors for supporting life: “the presence of liquid water; the
presence of a biologically available energy source; and the presence of the
chemical building blocks of life in a biologically available for.” The report also named temperature and water activity as additional key requirements.

Interestingly, the (stationary) Phoenix Mars Lander may have plopped down a spot that’s perfect for life. “What you
see is that Phoenix comes down as a clear winner — a much, much higher
habitability index than any of the other sites,” Stoker told conference
attendees, according to the report. “The Phoenix landing site is the most habitable zone of any location
we have ever visited on Mars.”

Huge Supernova Puzzles Astronomers

Scientists observed a huge supernova in 2005 that happened much earlier than predicted, leading to speculation that our theories about how black holes are formed need further refinement.

According to a report in The Future of Things , scientists from the Weizmann Institute of Science in Israel and San Diego State University detected a huge explosion—not the one from September, but another one—from a star that was roughly 50 times the size of our own sun. “In what they call a ‘first observation of its kind’ the scientists were able to notice that most of the star’s mass collapsed in on itself, resulting in a creation of a large black hole,” the report said.

What makes this particular supernova remarkable—aside from its enormous size—is that it happened much earlier than astronomers had predicted. That lends further credence to the theory that massive stars—those 20 or more times the size of our sun—can suddenly and violently end their lives by becoming black holes.

“This might mean that we are fundamentally wrong about the evolution of massive stars, and that theories need revising,” said Dr. Avishay Gal-Yam, from the Weizmann Institute’s Faculty of Physics, in the article. (Via Slashdot) (Image credit: Supernova 1994D / NASA)

Scientists See Asteroid Explode Above Earth, Someone Gets 100 Points

In a story worthy of Hollywood treatment, shocked astronomers in Sudan watched as an asteroid exploded above earth into a meteor shower, and then went into the desert to retrieve the pieces, according to an AFP report. A study in the British journal Nature concluded that this is the first time ever that scientists were able to recover pieces from a specific asteroid observed in space.

“Any number of meteorites have been observed as fireballs and smoking meteor trails as they come through the atmosphere,” said co-author Douglas Rumble, a researcher at the Carnegie Institution, in the article. “But to actually see this object before it gets to the Earth’s atmosphere and then follow it in—that’s the unique thing.”

Call to Arms: The International Space Station Needs Lasers

OK, let’s cut the crap here, NASA: After today’s near-evacuation, it’s clear that you need weapons on the International Space Station. And don’t forget to put web controls so we all can play.

Seriously now: This is seriously fraked up. The ISS is almost as big as a Corellian corvette and it’s up there defenseless, floating peacefully, sitting like a dinosaur-sized duck, waiting for one of the 18,000 pieces of tracked space debris to crack it open and take it down in a fiery ball of junk.

Sure, they have a escape spaceship for astronauts. In case things go bad—like they almost did today—they can jump in there and fly away before the worst happens. However, after all the money and effort put in the only human post in space, do we want to send everything to hell for a piece of orbiting crap? Wouldn’t it be better to install defense mechanisms against space debris—or, ah, hmmm, alien ships!—to preserve the ISS?

Technically, there are already weapon systems that may be altered to perform this task, but this is not an easy task. We know it is not as easy as firing a laser and taking down the incoming chunk of metal with a Star Wars explosion.

There’s a lot of things to be taken into account. First, you will need to detect the threat and fire from a very long distance, so the resulting effect doesn’t cause any harm to the ISS itself. Then, the method to take down the object will change depending on its nature. Is it a big satellite or just a big chunk of metal from a previous collision? Does the incoming object have explosive elements inside? If the object is too big and can’t be obliterated in a single shot, perhaps it would be better to have some kind of rocket that may approach the object and change its orbit by exploding near it? Perhaps some kind of emergency tug that can attach to the object and take it down?

We don’t know. Whatever NASA and its international partner can come up with, they need to do it as soon as possible. Things are getting complicated up there, and this doesn’t conflict with the international protocols against the militarization of space—which, in any case, are being constantly violated by the US, Russia, and China.

This will be a defense mechanism against space threats, and that’s exactly what the ISS needs. It is just too valuable to be left there with no protection. NASA, it’s time to get some pew pew action going on up there.

ISS Has Close Call with Space Debris

The crew of the International Space Station was forced to hide briefly in its escape capsule Thursday after a piece of space debris flew close by, NASA officials said.

The Expedition 18 crew members received an all-clear from Mission Control at 12:45 p.m. EDT Thursday, once the threat had passed. The crew took precautionary measures right after getting up this morning even though the chance of impact was low, the agency said in a statement.

Normally flight controllers steer the station to avoid the debris. But news of this particular piece came too late to execute an avoidance maneuver. Instead, the crew climbed into the Soyuz TMA-13 capsule and soft-locked the hatches for the first time, in case the collision turned out to be catastrophic.

Incidentally, the public naming contest for the new Node 3 capsule (pictured) is still ongoing. Serenity leads NASA’s choices, while Colbert tops the write-in votes. Cast your vote here.

ISS to Become Brightest Star in the Sky

The International Space Station will soon surpass Venus to become the second brightest object in the sky after the Moon, once astronauts install the fourth and final set of solar array wings as part of Space Shuttle Discovery mission STD-125 TS-119/15A, according to Slashdot.

The final section of the ISS’s structure will bring the station to a total length of 102 meters, and increase the amount of electricity available for science experiments by half, the report said. The mission will also help prep the station for a full crew size of six (instead of the current three). The shuttle mission launches tomorrow, assuming good weather, and will be the shuttle program’s 125th since its inception in April 1981.

Currently, Venus is the brightest object in the sky after the Moon, with an apparent magnitude that reaches -4.6 on occasion. Track the ISS and other space missions across the sky using NASA’s sighting calculator.
