November 2011: Life in the Astro-Blogosphere.

A “Warhol Moon!” (Photo mosaic by Author).

Wow, can you believe that 2011 is coming to a close? It seems that it was only yesterday that we where installing Windows 98 and fretting about Y2K, and now we have a decade plus of the 21st century under our belts… this month brings a pair of launches headed towards the Red Planet, a partial solar eclipse for distant lands, and a Tweetup for one of the aforementioned launches: [Read more...]

  NASA engineers directed the Stardust spacecraft to fire its rockets briefly on the of 17th of February, putting it on course for a new mission; a flyby of comet Tempel 1 February 14th of next year. If that comet sounds familiar, it should be; Tempel 1 was smacked by an impactor released from the Deep Impact space probe in 2005. The pass will allow scientists to see how the impact crater has evolved, as well as mark the first mission to re-visit a comet. Launched on February 7th, 1999, Stardust also returned a first ever sample of a comet. This sample has been the subject of much scrutiny by Earth-bound scientists, including that favorite obsessive/compulsive-creating crowd-sourcing project, Stardust@home. Hey, I’m still in the top 100, last time I checked…  NASA has also rechristened the spacecraft as Stardust NExT, or the New Exploration of Tempel. Not only will next years’ passage provide close-ups of the nucleus, but expect to see high resolution images of the coma and key insight into just how these Jupiter-class family of comets formed and evolved.
