ESA: Ariane-6’s launch systems tests “progressing well”
According to a press release today from the European Space Agency (ESA), tests of the launch systems for its new Ariane-6 rocket are “progressing well”, though this particular test program was unable to finish its launch countdown rehearsal on July 18th with an actual static fire engine test of the rocket’s first stage engine.
The launch simulation included the removal of the mobile gantry, the chill-down of ground and launcher fluidic systems, the filling of the upper and core stage tanks with liquid hydrogen (–253°C) and liquid oxygen (–183°C), and at the end of the test, the successful completion of a launch chronology up to the ignition of the Vulcain 2.1 engine thrust chamber by the ground system.
During the 26-hour exercise, the teams successfully tested many degraded and contingency modes, demonstrating that the launcher and the launch base fit correctly. Operational procedures, lower and upper stages, avionics, software, launch base and control bench worked correctly together, and the performance of the full launch system was measured with excellent results.
The last part of the test – a short ignition of the Vulcain 2.1 engine – had to be postponed to the next test session as time ran out. The teams are now working towards continuing the exercise, in preparation for a long duration hot firing test later this summer. [emphasis mine]
The highlighted words imply a certain leisureliness on ESA’s part, an impression that might be wrong but it is the impression this language gives out. One wonders why the launch countdown could not have been completed to that static fire engine burst. “Time running out” seems a very lame reason, especially since ESA no longer has the Ariane-5 rocket and the Ariane-6 to replace it is years behind schedule.
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 print edition can be purchased at Amazon or from any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. 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

Bob, it’s Europe, and it is unreasonable to deny the workers the right to a little break to drink a little wine and eat a little cheese just because they have no strategic space launch capability anymore. That would be uncivilized and American behavior which they simply cannot countenance!
MDN: Heh.
