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
This engine is still a test article and is not yet flight-worthy.
“The engine delivered is the first pathfinder engine to be mated with the Vulcan Centaur and will support ULA’s testing,” a Blue Origin spokesperson told SpaceNews. “We are planning on delivering the second engine in July.” A pathfinder is a development engine. Blue Origin has not said when a flight-qualified engine will be delivered.
…ULA set a 2021 target to fly its first Vulcan Centaur mission and needs two production-quality engines to build the launch vehicle for that mission. Flying Vulcan Centaur in 2021 is an imperative for ULA as it tries to win one of two contracts that the U.S. Space Force will award this summer to launch dozens of national security satellites between 2022 and 2027.
According to sources, frustration has been mounting at ULA as the company’s future is tied to the success of Vulcan Centaur and there is no room for error when it comes to the main engine.
I empathize with ULA’s frustration. The pace of development at Blue Origin has seemed incredibly slow in the past two years. They had begun static fire tests in 2018, and then — beginning with ULA’s decision to buy the BE-4 for Vulcan in May 2018 — for more than a year there was no news. It wasn’t until August 2019 that they announced completion of the first full power test. Even then, it took another whole year before they got to this point now, where they were willing to deliver a first test engine to ULA.
Building a new rocket engine is not simple, so these delays could be entirely reasonable. At the same time, the company’s overall pace in accomplishing anything has been glacial. For example, in the past three years it has repeatedly not delivered on its promises to start flying humans on its New Shepard suborbital capsule. Four months ago, in their most recent promise, they said they would need three more unmanned test flights of New Shepard before they’d put humans on it, and that all those flights (including the manned one) would occur this year. Yet nothing has happened since.
While I truly want Blue Origin to succeed, one must cast a cold eye on what is really happening. If they wish to really compete with SpaceX they have got to pick up their pace.
