 Sitting on its three spindly legs since landing in the Martian arctic on May 25th, the Phoenix Lander’s mission has been extended again into December. The lander has performed the most detailed analyses of the Martian soil and has for the first time verified the presence of water ice on the red planet. This is the second time that the Phoenix mission has been extended, and probably will be the last.

 Probing the secrets of science was supposed to get easier when the Large Hadron Collider in Europe was switched on earlier this month. Instead, the $10 billion, 27 km (17 mile), super-cooled atom smasher broke during the first test, a setback that will delay any further experimentation until the spring of next year. Buried 100 meters (330 feet) below the CERN particle physics center on the border of France and Switzerland, the collider was 14 years in the making and since conception had been sparking fears of inducing doomsday by creating a micro black hole of magnetic monopole or other such theoretical Earth-destroying phenomena.

 Even though the Phoenix Lander has shown that Mars is pretty much as dry as we thought it was, a new study suggests that the massive valleys we see on the red planet now were carved out by wet and dry seasons much like Earth’s current deserts. This stands in stark contrast to theories that the networks of valleys were the result of short-lived catastrophic flooding that lasted from a few centuries to a few millennia. The latest models indicate that wet periods on Mars could have lasted longer than 10,000 years.

 Two days later than originally planned, the space shuttle Atlantis rolled out to is launch pad on the Atlantic Coast on Thursday. The move to Launch Complex 39A, the primary shuttle launching platform, was delayed by Tropical Storm Hanna, which skirted by Florida’s coast earlier in the week before charging up the eastern United States seaboard. The storm dealt no damage to the Kennedy Space Center in Cape Canaveral, Florida. The two-day delay will ripple through the mission timeline, pushing back the launch to service the Hubble Space Telescope to no earlier than October 8, 2008.

 In the past week both Russia’s Progress cargo ship and the ESA’s Jules Verne ATV undocked from the International Space Station. Both of the unmanned cargo spaceships are on their way towards a fiery destructive reentry over the Pacific Ocean. Progress 29 undocked on Monday and the Jules Verne ATV on Friday, though both will remain in orbit for several more days to conduct further tests.

 Faced with a growing chorus of legislators from around the country calling for NASA to reexamine its plans to retire the remaining three space shuttles in 2010, the US space agency has commissioned an internal study to examine the ramifications of delaying certain shuttle flights or extending the retirement deadline in favor of more launches. The decision was spurred by international concerns over Russia’s soon-to-be monopoly on human transport to the International Space Station, as their Soyuz capsule is the only other manned craft capable of docking with the orbital outpost.

In orbit of our blue marble are at least 10,000 bits of space litter, ranging from functioning satellites to discarded rocket segments to the remains of satellites obliterated by ground based rockets. Also up there are satellites that have simply died and are circling our planet until their orbit decays and they fall out of the sky. Either way, most of the 10,000 tracked pieces of debris would pose a threat to any craft in their path, be it a space shuttle or the International Space Station with its massive sweeping solar panels. Such a threat arose this week for the ISS with its path coming uncomfortably close to that of Object #33246 - the remains of a defunct Russian satellite.

 Inexplicably, a computer virus designed to steal the passwords of online gamers has appeared on laptop computers in use aboard the International Space Station. Deemed a low risk, the virus was detected late last month, and according to NASA, does not pose a threat to the space station. The virus several laptop computers used to tabulate data for minor experiments and for personal use by the three astronauts aboard the ISS. There are 71 laptops aboard the orbital outpost, though not all of them are vulnerable to the Windows-based virus, many lack basic virus protection.

 US Senator and Republican presidential candidate John McCain (R-Arizona) has added his voice to the growing congressional chorus calling for more money for more shuttle flights. In the face of an increasingly tense relationship with Russia - the only other nation capable of delivering humans to the International Space Station - McCain and two other senators have written to President George W. Bush, imploring the president to direct NASA to hold off for at least one year any actions that would prevent space shuttle flights beyond 2010.

 Having successfully survived another southern hemisphere Martian winter, the solar-powered Mars rovers are back at work, with Opportunity again stealing the spotlight. Having rolled down into Victoria Crater nearly a year ago, NASA mission controllers at the Jet Propulsion Laboratory in Pasadena, CA, have accomplished everything they set out to do when they went into the crater, and are now taking the same route back out. Their efforts could be stymied by a potential wheel failure, though - Opportunity experienced an unsettling power spike in its left front wheel motor, a similar electrical current spike spelled doom for the right front wheel of the rover’s twin Spirit in 2006.
