Unmanned sail prototype prepares for launch
A prototype of an unmanned sailing ship will begin a test voyage this fall.
Although Harbor Wing will operate without a captain and crew by sailing on a pre-programmed course, “the man is always in the loop,” Ott said. An operator, seated at a computer that could be hundreds of miles away, can control the craft with keystrokes that relay commands via satellite. The transmission gap, from order to receipt, is only 18 seconds, which “on the open ocean is not much,” he said, “so you have very close control.”
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

Given how often ships at sea can’t get any connection – that doesn’t reassure me.
