Falcon 9 upper stage has issue preventing de-orbit burn; SpaceX pauses launches
According to a SpaceX tweet yesterday afternoon, the upper stage of the Falcon 9 rocket that successfully launched 25 Starlink satellites “experienced an off-nominal condition” when it was preparing to do its final de-orbit engine burn.
During today’s Falcon 9 launch of @Starlink satellites, the second stage experienced an off-nominal condition during preparation for the deorbit burn. The vehicle then performed as designed to successfully passivate the stage. The first two MVac burns were nominal and safely deployed all 25 Starlink satellites to their intended orbit.
Teams are reviewing data to determine root cause and corrective actions before returning to flight
It appears that SpaceX has temporarily paused its launch schedule while it reviews this incident, shifting a launch that was supposed to occur last night back three days to February 5th. While the launch itself was successful, the company likely wants to get a handle on what went wrong before resuming launches.
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
