Stratolaunch airplane 40% complete
The competition heats up: Stratolaunch has revealed that construction of the gigantic airplane — the largest ever to fly — that will take its rockets into the air is now about 40% complete.
The first flight is still scheduled for 2016. The article also includes some good analysis which indicates the competitive problems Stratolaunch faces:
Its Orbital Sciences-supplied solid-fuel rocket will be able to carry 15,000 pounds to low Earth orbit. But this is about half the lift of the competing SpaceX Falcon 9 and just 30 percent that of a Boeing-built Delta IV. Stratolaunch will be able to orbit only smaller satellites.
Nonetheless, watching this mother-ship take off will be quite breath-taking.
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. from any other book seller, or direct from my ebook publisher, ebookit.
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

The differences between them and SpaceX matter only in terms of the size of the average satellite and the relative cost to launch one. I haven’t done the analysis but they could be competitive for the size of satellite that they can launch.
