ULA delays Delta 4 and Atlas 5 launches for same reason
Because of a concern about the same component used on both its Atlas 5 and Delta 4 rockets, ULA has now delayed the upcoming launches of both rockets.
Concerns over an unspecified part flying on the upper stages of United Launch Alliance’s rockets have delayed the launch of a GPS satellite on a Delta 4 booster from July 25 to no earlier than Aug. 22.
The same issue has also delayed an Atlas 5 launch.
The delays are related to engineers’ concerns over a common component that flies on the upper stages of the Atlas 5 and Delta 4 rockets, a ULA spokesperson said Wednesday.
Both rockets use the same Aeroject Rocketdyne engine in their upper stages, but an official from that companY said that its engine is not the issue. The upper stages also use the same avionics systems.

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
