One launch today by SpaceX, while ULA scrubs for the second time in two days
SpaceX today successfully launched another 28 Starlink satellites, its Falcon 9 rocket lifting off from Vandenberg Space Force Base in California.
The first stage completed its 8th flight, landing on a drone ship in the Atlantic.
ULA for the second day in a row was forced to scrub a launch of a Viasat communications satellite due to “a reoccurrence of the issue with the Atlas V booster liquid oxygen tank vent valve.” No new launch data has as yet been announced.
The contrast between these two rocket companies here is truly striking. In the past two days SpaceX’s reusable Falcon 9 has launched twice, like clockwork, while ULA can’t get off the ground because of a valve issue, the kind of niggling problem that routinely scrubs its launches. It is thus rare that ULA launches on time, on schedule, as planned.
SpaceX’s launch however sets a new record for successfully launches in a single year by the entire world, 257, breaking the record set last year. These numbers are two to five times what the global launch industry managed annually for most of the space age, and signal the renaissance in rocketry brought on by Elon Musk and SpaceX. Nor I think have we reached peak numbers. Not even close.
The leaders in the 2025 launch race:
145 SpaceX (a new record)
67 China
14 Rocket Lab
13 Russia
SpaceX now leads the rest of the world in successful launches, 145 to 112.
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
