Iridium switches two upcoming launches to reused Falcon 9 first stages
Capitalism in space: Iridium has revised its launch agreements for two upcoming launches using the Falcon 9 rocket to have both use previously flown first stages.
While the article provides a lot of good background on SpaceX’s increasing sales of reused first stages, including the fact that 20% of SpaceX’s launches this year might end up using re-used first stages, an amazing number consider this is also the first year they are doing so, this quote from the article however is even more astonishing:
Importantly for Iridium, and for the launch market as a whole, Iridium revealed in its announcement that the cost of insuring the Iridium NEXT-4 and -5 missions did not change with the switch to flight-proven boosters. “Iridium confirmed with its insurers that there is no increase in premium for the launch program as a result of the use of flight-proven Falcon 9 rockets, further supporting Iridium’s conclusion that the risk profile is unchanged,” noted the release.
Overall, this is an excellent sign that the all-important insurance market element of spaceflight continues to see no increased risk with launching atop flight-proven boosters.
One of my sources close to SpaceX says that the company will likely not fly these reused first stages intact more than twice, but will still salvage the engines for additional reuses. Considering the engines are the most expensive component, this makes great sense. Even if SpaceX doesn’t fly a first stage intact, it has developed an efficient and effective method for recovering the engines for reuse.
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

Amusingly, just reusing the engines, will inadvertantly forward the Vulcan business case for ULA. The original plan was to sever the tanks and have the engine complex return for reuse.
(Or Abilene from Arianespace).
Of course, I expect that it will also demonstrate how dumb a model it is, when the other option is recover the entire stage intact for reflight. (Looking at you Block 5!!!)
