A glimpse at China’s unmanned cargo freighter
The competition heats up: A Chinese state media report just released included footage showing China’s unmanned cargo freighter, Tianzhou-1, as engineers prepare it for its April launch to their test space station module, Tiangong-2.
Two important take-aways from this report. First, note in the simulation showing the docking of the freighter to Tiangong-2 the size comparison. The two craft are almost the same size, showing that Tiangong-2 really is nothing more than a test module, not large enough for long sustained space station operations. The freighter meanwhile is quite substantial.
Second, the report says they are aiming for a 2018 launch of the first module of their full size station.
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
