Dawn’s chief engineer gives us a detailed update
Link here. Chief engineer Marc Rayman loves to write about Dawn, and his posts on the Dawn blog are probably the most information-packed of any spacecraft blog I have ever read. Key quote this time:
Dawn’s extensive photographic coverage of the sunlit terrain in early May will include these bright spots. They will not be in view, however, when Dawn spies the thin crescent of Ceres in its next optical navigation session, scheduled for April 10.
The orientation of the spacecraft and asteroid now are such that there is no point taking pictures, as most of the asteroid is in darkness.
Read it all, however. He gives a masterful overview of what is going to happen in the coming months.
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 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

He has a wonderful way of writing about the spacecraft as a living thing. Thank you for the link.
