New Horizons completes third course change engine burn
New Horizons has successfully completed the third of four engine burns required to adjust its course to fly past Kuiper Belt object 2014 MU69 in 2019.
This burn lasted 30 minutes, and having exceeding the second burn on Sunday is now the longest engine burn that New Horizons has done since launch.
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

Reflect for a moment on the robustness of machines that operate in a hostile environment for years. Sure, they’re expensive, but the engineering and manufacture are breathtaking.
Agree, I was a fan of Pioneer 10 growing up, especially after it left the Solar System and was till sending back observations 30 years after launch! Incredible.
Voyagers 1 and 2, Viking 1 and 2, Spirit and Opportunity, the list of Spacecraft that have exceeded expectations is impressive and tends to get forgotten by the public.
