Stratolaunch shifts to the small sat marketThe competition heats up: Even as Vulcan Aerospace, the company building the Stratolaunch air-launch system, considers its options for the second stage rocket that it will use, it has decided to shift its focus towards the small satellite market, including cubesats.
In a sense, they are now aiming at the same cubesat/smallsat market that Virgin Galactic wants with its LauncherOne air-launched rocket. Whether they can build a system cheap enough for these small satellites to afford, however, remains the big question. Their shifting focus, like Virgin Galactic’s, does not bode well for them.
Stratolaunch of Huntsville, Alabama, has already gone through two earlier iterations of its launch vehicle. When Stratolaunch unveiled its plans in December 2011, it planned on using a variant of SpaceX’s Falcon 9 rocket. Less than a year later, though, Stratolaunch announced it was ending that agreement because SpaceX wanted to focus on the standard version of its Falcon 9.
Stratolaunch then teamed with Orbital Sciences Corp., now Orbital ATK, to develop a launch vehicle. That rocket, called Thunderbolt, featured two solid-fuel stages provided by ATK and an upper stage powered by RL-10 engines from Aerojet Rocketdyne. Like the earlier SpaceX design, Thunderbolt was designed to launch medium-class payloads.

Stratolaunch, though, has set that design aside as it seeks to launch smaller satellites, where the company sees a burgeoning market.
One wonders if the cost of building Stratolaunch will be more than this smallsat market can bear.
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
