SpaceX Dragonfly test vehicle arrives in Texas
The competition heats up: Dragonfly, SpaceX’s test capsule for testing vertical rocket landings, has arrived at their facility in McGregor, Texas.
DragonFly will be attached to a large crane, ahead of a series of test firings of its SuperDraco thrusters to set the stage towards the eventual goal of propulsive landings. The first test is set to take place in the next few weeks to kick start around two years of incremental testing.
Similar in concept to Grasshopper, Dragonfly is not an actual Dragon capsule, but a testbed for figuring out how to do vertical landings with a capsule, using thrusters.
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
