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.
"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
From June 23 to July 3, the UWE-4 cubesat fired its NanoFEEP thrusters several times to reduce its altitude by more than 100 meters. By comparison, natural orbital decay would lower the altitude 21 meters in the same timeframe, according to a University of Wuerzburg news release.
One July 2, as the UWE-4 cubesat was lowering its altitude, the University received a warning from the U.S. Air Force’s 18th Space Control Squadron of a July 5 conjunction with a retired Iridium satellite. When UWE-4 mission operations personnel analyzed the conjunction, they determined the UWE-4 cubesat would not collide with the Iridium satellite because it would be orbiting at a lower altitude. As a result of the analysis, UWE-4 mission operations personnel continued firing thrusters to lower the cubesat’s altitude. They received no further conjunction messages.
The thrusters were built by Morpheus Space. Incorporating thrusters onto a cubesat, the size of which fits on the palm of your hand, is quite amazing, and illustrates the growing capability of these tiny satellites.
