| NASA Tracking Air Leak in International Space Station November 29, 2007 7:45am in science |
SPACE.COM reports that NASA is investigating a minor air leak on board the International Space Station. This leak appears to be minor and is little risk to the crew or the upcoming STS-122 mission to be launched early December. NASA is having astronauts inspecting the seals beteern the Destiny Lab and the Harmony Modules as well as the seal between the Harmony Module and the Shuttle Docking Port. The good news is that the tests checking the internal pressure of the ISS are showing no signs of decay. NASA hopes to have this issue resolved although no one on the ground or on the ISS seems to be overly concerned showing seemingly that this possible leak really does show no signs of being a major risk.

| Space Shuttle Discovery Launches Towards International Space Station October 23, 2007 12:16pm in science |
 Space Shuttle Discovery launched today at 11:38 AM on a key mission for the construction of the International Space Station. STS-120, the second shuttle mission to be commanded by a woman, Pamela Melroy, will be delivering the Italian-built Harmony module to the ISS. The mission is scheduled to last 14 days and include 5 spacewalks. Full Story [Space.com] |

| NASA Gives Discovery the Go Ahead for Launch October 17, 2007 12:37pm in science |
 NASA has given Space Shuttle Discovery a green light for launch currently scheduled next week on October 23rd at 11:38 am. Concerned about three of the reinforced carbon carbon, engineers have decided that there is no risk to the mission or Discovery's crew. The STS-120 mission will deliver the Harmony node to the International Space Station. Discovery will also do a crew exchange for the ISS dropping off Daniel Tani and bringing home Clayton Anderson. Assuming weather and any other issues permit, Discovery will launch October 23rd and land November 6th. It's Discovery's first launch since December 2006.

| Astrophysics Lab Replaces Supercomputer with 8 PS3s October 17, 2007 12:19pm in science |
 An astrophysics lab has replaced a supercomputer they use for research with 8 PlayStation 3 consoles. Some reasons behind this include the fact that using the supercomputers cost them $5000 a pop which adds up rather quickly. The whole idea that the PS3 can run Linux is also a plus as it allows the lab to run them the way they want uninhibited.
"The interest in the PS3 really was for two main reasons," explains Khanna, an assistant professor at the University of Massachusetts, Dartmouth who specializes in computational astrophysics. "One of those is that Sony did this remarkable thing of making the PS3 an open platform, so you can in fact run Linux on it and it doesn't control what you do."
The 8 PS3s were donated by Sony and stringing them together with proper otimized code allows them to function very much like a supercomputer. The experiment they're running is to calculate the amount of gravity that would be generated should a black hole swallow a star. This grid has apparently been up for a month and the 8 PS3s apparently generate the processing power of about 200 supercomputer nodes that they used to use.
