Update on Superheavy/Starship: Both ships doing final static fire testing
Link here. The report includes a lot of very interesting information about how SpaceX is evolving its launch platforms and the tank farms that fuel the stages in order to make them operate more efficiently. For example:
In the past, on Pad 1, SpaceX had only four Liquid Oxygen (LOX) Pumps and six subcoolers, and three Liquid Methane (LCH4) Pumps with three subcoolers. This setup allowed SpaceX to start booster load at T-41:15 on Flight 11.
On Pad 2, SpaceX has five pumps and about 10 subcoolers worth of capacity on the LOX side, and four pumps alongside about six subcoolers worth of capacity on the LCH4 side. With these upgrades, along with larger supply lines, SpaceX can now load a full booster within 30 minutes, and each LOX ring takes only about 90 seconds to load. This now means SpaceX can load the Superheavy booster faster than a Falcon 9 and carry over 10 times the propellant. [emphasis mine]
Many of the tests have been more to prove out the fueling systems and launchpad than to test Superheavy.
Other tests however have been to prove out the new Raptor-3 engine. The company have increased the number of engines step by step so that the next test will be the first to test all 33 engines. I suspect that test will also be the full dress rehearsal countdown prior to launch.
Starship meanwhile is undergoing testing on the company’s nearby Massey test stand, the one that I think was rebuilt after an explosion last year.
Stay tuned. It appears the next and 12th orbital test flight will not be long in coming.
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

Everything okay?
“Similarly Starship…”
I hope you didn’t fall.
No word on the impact of popping a V3 engine at McGreggor last week? Cheers –
Jeff Wright: Forgot to clean up some earlier writing. Fixed. Thanks.
