 The Gamma-ray Large Area Space Telescope keeps running into problems getting off the ground, quite literally. Originally slated to launch today (and before that, on May 16, then June 3rd, then the 5th), GLAST is now targeted for a June 11th launch. The gamma ray observing telescope has been mounted atop its Delta II rocket since May waiting to head into orbit.

 When it comes to getting into space, there’s no such thing as too many options. At least, that’s what NASA is trying to convince the European Space Agency to start thinking. With the US space shuttle fleet due to retire in just over two years, the world will suddenly be limited to using Russian spacecraft to get humans into space. China has developed the technology, but due to their go-it-alone approach, they aren’t apt to start playing nice and sharing seats into orbit.

 Launch Complex 39A, the primary launch pad for NASA’s space shuttle fleet at the Kennedy Space Center, suffered serious damage during last weekend’s launch of the space shuttle Discovery. Regularly inspected after launches, the north flame trench, which is designed to catch and redirect the flames that shoot out from the shuttles’ external booster rockets, was found to have an unprecedented amount of damage. Brick and mortar debris blasted from the trench was found all the way up to the perimeter fence, some 450 meters from the pad.

 Weighing in at three Earth masses (that’s 19,756,000,000,000,000,000,000,000,000 tons), the lightest extrasolar planet we’ve yet discovered is a mere 3,000 light-years away. The so-called “super Earth” orbits the star MOA-2007-BLG-192L; tack a “b” onto the end of that and you’ve got the planet. MOA-2007-BLG-192L is estimated to be about six percent of our sun’s mass, which is just below the mass needed to trigger and sustain nuclear fusion in its core, making it a brown dwarf. However, the margin of error with the estimate could have it ranging up to eight percent, which would just barely be enough to start a fusion reaction.

 Astronomers have revised their map of our Milky Way galaxy yet again, and this time we’re in for more big changes. As you may recall, version 2.0 of our galactic understanding replaced what we thought to be the giant central spheroid bulge of our galaxy with a giant bar of similar composition and four spiraling arms. The latest iteration of the galactic map has reduced our galaxy to two major arms and two minor arms that are spurs off of the larger two.

 On Monday the space shuttle Discovery docked with the International Space Station, carrying with it a massive new Japanese lab, a new crewmember, and a replacement toilet pump. The two orbital craft met 335 km over the Pacific Ocean, where Discovery performed a slow back flip so that the ISS crew could take hundreds of detailed photos of the shuttle’s heat tiled belly for transmission back to the surface for analysis.

 Mission operators as the University of Arizona have been sure to get plenty of practice operating Phoenix from afar before they dig in, literally. Throughout this week the operators of NASA’s $420 million Mars lander have been touching the soil at the probe’s arctic landing site and performing “dig and dump” maneuvers, which are very much what they sound like.

 To infinity and beyond, indeed. As part of a partnership between Disney and NASA, a 12-inch figure of Buzz Lightyear of Toy Story fame signed up as an eighth astronaut aboard Discovery, seeking to expand and invigorate childhood space, science, and math education. Back in the cargo hold of Discovery was the Japanese Experiment Module of JAXA’s Kibo Laboratory - this massive module is the size of a touring bus and fills the entire cargo hold of the space shuttle.

NASA’s Phoenix Mars Lander is stretching out. Working from Earth, operators have managed to successfully unfold the lander’s eight-foot-long arm. The arm was manipulated so that the camera at its end could look underneath the lander, a blind spot for the top-mounted stereo camera. The images showed an area where the lander’s rocket motor had blown away the overlying soil, exposing tabular formations that appear to be either ice or rock.

 Of all the expensive complicated things that could have broken on the International Space Station, it had to be the toilet. For the rest of us Earth-bound humans, having one commode for three people is no big problem. If it breaks, you can use the neighbors and call the plumber to fix it for a few dollars. In space, however, nobody can hear you scream inside the bathroom. There is one toilet on the ISS, inside the Russian-built Zvezda module, and in recent days it’s started to act up.
