Antares Engine Problems Were Not News

Before explosion, NASA knew aging Soviet engines posed risks, LA Times

"Years before an unmanned rocket erupted in a fireball in October, NASA officials knew the metal in its 50-year-old Soviet-made engines could crack, causing fuel to leak and ignite, government documents show. As early as 2008, a NASA committee warned about the "substantial" risk of using the decades-old engines, and a fire during a 2011 engine test in Mississippi heightened the agency's concern. The engines had a "fundamental flaw in the materials," said a top manager for NASA's contracted rocket builder, Orbital Sciences, in a 2013 interview with an agency historian. The Soviet engines were built in the 1960s and 1970s in a failed attempt to take cosmonauts to the moon."
