Iridium launches might use reused Falcon 9 first stages


A quick holiday fund-raising campaign for Behind the Black!
 
Scroll down to read this post.
 
In past years I have managed to avoid asking for donations for Behind the Black during the holiday season. My finances however now compel me to do a short one-week fund-raiser, from November 11 to November 17.
 
I do not use Twitter for ethical reasons, which I have been told cuts down on traffic to the website. So be it. Furthermore, Facebook has clearly acted in the past two years to limit traffic to Behind the Black, almost certainly for political reasons. So be this as well. Finally, I do not post outside ads, as I have found them annoying to my readers and not that profitable to me.

 

Therefore, I need to ask for the direct support from my readers. If you like what I do here, please consider contributing, either by making a one-time donation or a monthly subscription, as indicated in the tip jar below.


 

Regular readers can support Behind The Black with a contribution via paypal:

Or with a subscription with regular donations from your Paypal or credit card account:


If Paypal doesn't work for you, you can support Behind The Black directly by sending your donation by check, payable to Robert Zimmerman, to

Or you could consider purchasing one of my books, as indicated in the boxes scattered throughout the website. My histories of space exploration are award-winning and are aimed for the general public. All are page-turners, and all not only tell the story of the beginning of the human exploration of space, they also help explain why we are where we are today. And I also have a science fiction book available, Pioneer, which tells its own exciting story while trying to predict what life in space will be like two hundred years in the future.

 

Note that for this week only I am also having a sale on the purchase of the last 20 hardbacks of Leaving Earth. (Click on the link for more information about the book, which was endorsed by Arthur C. Clarke himself!) This award-winning out-of-print book is now only available as an ebook, but I still have a handful of hardbacks available, normally for sale for $70 plus $5 shipping. For this week only you can buy them, personally autographed by me, for $50 plus $5 shipping! Just send me a check, payable to Robert Zimmerman, to the address above, with a note saying that the money is for the Leaving Earth hardback.

 

Please consider donating. Your help will make it possible for me to continue to be an independent reporter in the field of space, science, technology, and culture.

Capitalism in space: Iridium is considering using Falcon 9 previously flown first stages for its later already contracted launches with SpaceX.

Iridium is launching 75 of its 81 second-generation Iridium Next satellites using eight Falcon 9 launches, the first of which took place Jan. 14. In a conference call with reporters June 19, Desch said Iridium’s original contract with SpaceX calls for new Falcon 9s for each mission, but if SpaceX can improve its launch schedule with pre-flown stages, Iridium would consider them for missions in 2018. “While we are currently flying first flown launches, I’m open to previously flown launches, particularly for the second half of our launch schedule,” said Desch.

Desch said there are three criterion by which Iridium would decide whether to use a pre-flown rocket: schedule, cost and reliability — of which schedule is the most important. “Would [pre-flown rockets] improve the current launch plan that I have with brand-new rockets that I’ve basically contracted for a number of years ago and have budgeted for and have paid for?” Desch asked. “That’s the first thing: will they improve my schedule, because schedule to me is very very important.”

I think this tells us that Iridium is waiting to see if this week’s launch of a Bulgarian satellite on a reused first stage is successful. The article also also notes that they are still negotiating over price for using “flight proven” first stages.

    If I recall correctly SpaceX doesn’t plan to give a substantial discount on “flight proven” boosters until the ~$1 billion in development costs (for the ability to recover the first stage) have been recouped. I can’t wait until they have the ability to reuse the fairings in addition to the first stage and can offer prices accordingly.

    As far as India’s competitive prices, that’s only one aspect that the market looks at. Reliability and schedule assurance are also important considerations and it remains to be seen if the GSLV is going to be a reliable vehicle. According to Wikipedia the GSLV mk 1 has had two successes, three failures, and one partial failure. The mk 2 is a little better with four successes and one failure.

    I’m admittedly partial to the home team, but SpaceX’s record is markedly better considering the innovation and rate of launches. Compare that to ISRO’s launch vehicles which, to this lamen, appear lower tech. Sorry Robert, I know those are your peeps, but SpaceX will wipe the floor with em! :)
