SpaceX sets May 10 for next launch, the first for Falcon 9’s final design

Capitalism in space: After analyzing the data from Friday’s static fire dress rehearsal, SpaceX has now scheduled the launch of Bangabandhu-1, Bangladesh’s first communications satellite, for May 10.

The significance of this launch is that it will be the first of what SpaceX calls the Block 5 version of this Falcon 9 first stage, a final design intended for many reuses and quick turnaround.

The star of the show is the new, unflown first stage core 1046, which is the first “Block 5” Falcon 9 first stage. Block 5 is the final major upgrade to the Falcon 9, the culmination of over 10 years of development and evolution of SpaceX’s workhorse rocket.

Block 5 has numerous advantages over past versions of the Falcon 9, notably including higher thrust engines, improved and more resilient recovery hardware, and the ability to be reflown within 48 hours of landing after a previous mission. Block 5 was also designed to meet – and in some cases exceed – NASA’s strict Commercial Crew Program requirements, which SpaceX must follow in order to be able to fly NASA astronauts, expected to begin in early 2019.

Block 5 cores are also expected to be reused 10 times before undergoing any major refurbishment, and SpaceX hopes to fly each booster up to 100 times before it is retired.

NASA has demanded that SpaceX fly at least seven different launches with the Block 5 stages before it will permit its astronauts on board (unlike SLS, where NASA has even considered flying astronauts on board with no previous test flights). Thus, getting this rocket flying is crucial to getting Americans back in space, on an American-made rocket.

Genesis cover

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 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

    Has NASA demanded they fly 7 new boosters, before human flights. 7 flights of the new configuration. The same booster 7 times?

    That has been unclear for a while.

    I think 7 new boosters in this config is a bit much, since SpaceX is likely to not build too many of them if the plan to spend on BFR/BFS instead of Falcon. And if they get BRF done in their expected decade, 7 booster cores is potentially 700 flights, which probably can bridge them most of the way.

    7 flights of the same booster is probably not likely either, just because they will want to examine/review before reflight so getting one booster to 7 seems unlikely in time.

    7 flights total is more likely, but would be nice to see confirmed.
