Are Old Engines Good For New Rockets?

40-Year-Old Russian Engine at Heart of Rocket Investigation

"The thing to keep in mind in all this is that we don't know what caused the mishap," Cowing cautions. "We all saw the explosion at the bottom of the rocket, but that doesn't mean anything. These investigations take time, and sometimes we don't even end up with all the answers."

"Not that older equipment is necessarily flawed. NASA Watch publisher Keith Cowing, with whom I also spoke on the phone today, says: I don't necessarily have a problem with old stuff, if you maintain it. If it used to work, it still can work. There are DC-3s in Antarctica that have been rebuilt three times that fly people to the South Pole. It's the issue of, does the machinery do a task that you need it to do? Do you understand it well enough that you can maintain it in operating condition, and does it make sense financially?"

"Although investigators are keeping their options open, a prime suspect is expected to be a potential failure mechanism involving the AJ-26, a liquid oxygen/kerosene-powered engine originally developed for the Russian space program as the NK-33. An AJ-26 slated to power an Antares on a mission to the ISS in 2015 experienced a failure during a hot-fire test at NASA's Stennis Space Center in Mississippi on May 22."
