The competition heats up: SpaceX has revised the schedule for its next three launches, pushing back two weeks so engineers can review issues with the Falcon 9 upper stage engine.
The debut launch of the upgraded Falcon 9 successfully deployed Canada’s Cassiope spacecraft into orbit on September 29. However, after safely deploying its payloads, the upper stage was then set to restart its Merlin VacD engine for a second burn related to SpaceX’s ambitions to create a fully reusable launch system. An anomaly with the restart held no mission impact, but the company’s CEO and chief designer, Elon Musk, did note they expected to implement corrective actions ahead of the next launch. “In the case of the upper stage relight, we initiated relight and the system encountered an anomaly and did not complete the relight. We believe understand what that issue is and should have it addressed in time for the next flight of Falcon 9,” he noted. “We essentially saw the engine initiate ignition. get up to about 400 psi and then it encountered a condition that it didn’t like. We have all of the data from the restart, so I am confident that we will be able to sort it out and address it before the next flight. We just have to iron out some slight differences of it operating in vacuum.”
I find Musk’s vague terminology about the engine issue to be interesting. I wonder if the “condition” the engine “didn’t like” was when the engine exploded, as some have suggested. (I personally am skeptical the engine exploded, however, as such a failure would probably require a much longer delay to deal with.)
Either way, the next few months should be a busy time for commercial space. Not only does SpaceX have two major commercial launches and a Dragon mission to ISS, Orbital Sciences has its next Cygnus cargo mission and Virgin Galactic claims it will be ready to fly SpaceShipTwo with passengers.

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
