Engine problems on a Delta 4 rocket launch two weeks ago could delay the launch of the Atlas 5 rocket scheduled to lift the X-37B on its next mission.
Engine problems on a Delta 4 rocket launch two weeks ago could delay the launch of the Atlas 5 rocket scheduled to lift the X-37B on its next mission.
Don’t ask me why the military would delay an Atlas 5 launch because of problems on a Delta 4. It seems to be left over caution from the 1960s, when no rocket was reliable and they were trying to figure out how to do it. Now, it simply seems silly.
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

Both the Delta IV and the Atlas V use variants of the RL-10 engine in their upper stages. Given that both variants are produced by the same company (and I assume in the same plant) it would seem prudent to at least look into the issue to make sure it’s not common to both engine variants.
Patrick,
An excellent point. I hadn’t realized they used a variant of the same engine.
