Cutting Open a Heatsink Heatpipe To See Inside

Cutting Open a Heatsink Heatpipe To See Inside:


An anonymous reader writes "Frostytech gets to the heart of Zalman's CNPS11X heatsink by cutting a section of heatpipe from the CPU cooler to inspect its inner composite heatpipe wick structure. Now that's an in-depth heatsink review! Interesting photos of the dissected heatpipe's composite wick — sintered copper powder on top and axial groove wick below — that you're unlikely to see elsewhere. In the late 1960s the first commercial heatpipes were used by NASA to stabilize satellite temperatures; now they stabilize multi-core processors."

Russian space caves on the Moon

Russian space caves on the Moon: Some Russian scientists want to build a space colony inside a network of caves on the Moon. No, really. It's hard to tell, from the Reuters story, how much support this plan actually has from the people who hold the purse strings.



By the light of the super full moon

By the light of the super full moon:


This photo was taken last March 19 in Cordoba, Spain. Photographer Paco Bellido captured a particularly special full moon—it appeared larger than any full moon had in 20 years. NASA explains:

Full Moons vary in size because of the oval shape of the Moon's orbit. It is an ellipse with one side (perigee) about 50,000 km closer to Earth than the other (apogee). Nearby perigee moons are about 14% bigger and 30% brighter than lesser moons that occur on the apogee side of the Moon's orbit. The full Moon of March 19th occurs less than one hour away from perigee--a near-perfect coincidence1 that happens only 18 years or so.

NASA Charters Flights Aboard Virgin's SpaceShipTwo

NASA Charters Flights Aboard Virgin's SpaceShipTwo: Zothecula writes "Although Virgin Galactic is generally known as a space tourism company, it sees research experiments as a future mission segment and significant business opportunity. To this end, the company has signed a contract with NASA to provide up to three charter flights on its SpaceShipTwo suborbital spaceplane. The deal follows the curtain closing on the Space Shuttle program earlier this year and is part of NASA's Flight Opportunities Program, which is charged with providing reduced-gravity environments for research experiments while encouraging the emerging commercial space industry."
In related news, a 68,000-sq. ft. facility has opened in California that will assist in the assembly of SpaceShipTwo spaceplanes.

NASA Game Lets You Build Complex Space Networks

NASA Game Lets You Build Complex Space Networks: gregg writes "According to this article, a new game called NetworKing, developed at NASA's Ames Research Center, 'lets players build fast and efficient communication networks by first setting up command stations around the world and then linking them to orbiting satellites and space telescopes. Resources are earned throughout the game as players continue to acquire more clients.' The game is available for play through an internet browser, and also has downloadable versions for Windows and OS X."

Why Mars Is Not the Best Place To Look For Life

Why Mars Is Not the Best Place To Look For Life: EccentricAnomaly writes "A story over at Science News quotes Alan Stern (former head of NASA Science missions) as saying: 'The three strongest candidates [for extraterrestrial life] are all in the outer solar system.' He's referring to Europa, Titan, and Enceladus. So why is NASA spending $2.5B on the next Mars Rover and planning to spend over $6B more on a Mars sample return when it can't find the money for much cheaper missions to Europa or Enceladus?"

NASA Sues Apollo Astronaut To Return Moon Camera

NASA Sues Apollo Astronaut To Return Moon Camera: Hugh Pickens writes "The US government has brought a lawsuit against astronaut Edgar Mitchell, the sixth man on the moon, after discovering that Mitchell had approached a NY auction house trying to sell a 16-millimeter data acquisition camera that was supposed to have been left in the lunar module. Mitchell argues that too many years have gone by for the government to pursue the camera as stolen and besides, it was given to the now 80-year-old moonwalker as a gift in line with NASA's then-policies governing spent equipment. However, the government contends it has no record of the camera being given to Mitchell who elected to remove it from the lunar module before parting ways with the spacecraft and returning to Earth, and the judge has ruled that the government is not bound by the statute of limitations denying Mitchell's motion to dismiss the lawsuit. The Apollo 14 astronauts were not the only crewmates to salvage parts of their lunar module as mementos: Astronauts aboard Apollo 12 and Apollo 15 ripped off parts of their moonwalking suits' life support backpacks before they were discarded onto the lunar surface. But what makes Mitchell's case different is that other astronauts asked their bosses before each mission for permission and provided a list of items they planned to keep while apparently Mitchell didn't. 'They give me a list of things they're going to bring back,' said Deke Slayton, head of NASA's astronaut corps, who died in 1993. 'I give it to the program office and they bring 'em back.' For his part, Mitchell does not seem ready to give up the camera as the case prepares to go to trial next year. "

Apollo 11 customs form

Apollo 11 customs form:

 Images I 4460 I02 Apollo-11-Immigration-02


Do you have anything to declare? Yes, moon dust and moon rock. This is the customs form filed by NASA for the astronauts entering Honolulu after departing from the moon. The Atlantic recently posted it but Space.com has the full story in this 2008 article. Apparently, it was done more as a fun ritual than any governmental requirement. Still, a fascinating artifact!
