Bennu from 85 miles
The OSIRIS-REx science team today released a new image of Bennu, taken by the spacecraft from only 85 miles on November 16, two weeks ago Its contrast has been increased to bring out the details.
The asteroid continues to remind me of Ryugu, a rubble pile of boulders with few smooth spots. I suspect the OSIRIS-REx engineers are going to struggle as much as the Hayabusa-2 engineers are in an effort to find a safe spot to grab a sample. The advantage however for OSIRIS-REx is that the main body of the spacecraft doesn’t have to get as close to the surface as with Hayabusa-2. They will come down only close enough for the robot arm to touch down.
Rendezvous is set for December 3.
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. from any other book seller, or direct from my ebook publisher, ebookit.
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
