Comet landing site confirmedEuropean engineers have finalized the landing site on Comet 67P/C-G for Rosetta’s Philae lander.
The link includes much detail about what Philae will do both on the way down as well as after it lands. November 12 will be quite exciting.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon or from any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

It will be, indeed. One question: The news release states that Rosetta will accompany the comet through their closest approach to the Sun next August and onward to the outer Solar System. Will Rosetta require guidance from the ground to stay with the comet as they move away from the vicinity of Earth, or will this be a natural process?
With objects as small as the nucleus of Comet 67P/C-G, it requires significant engineering skill to keep Rosetta close by and in “orbit.” In truth, the spacecraft really isn’t in an orbit. Instead the two objects are orbiting the Sun in tandem with each other.
At some point, when Rosetta’s fuel supplies run low, a decision will have to be made. Either they can send it on its own path, or they can try to bring it down on the surface, as NASA engineers did with NEAR when it was traveling with the asteroid Eros.
That’s interesting. Thanks for the clarification, Bob. I wasn’t aware of the NEAR mission when it took place.
