Zuma Non-Update Update

Lost in space? Questions mount over fate of secret satellite as SpaceX pushes ahead, Washington Post

"U.S. Rep. John Garamendi (D-Calif.), who said he received a "preliminary briefing," had two concerns about the possible loss of the satellite. "One is the loss of the intelligence that would have been available," he said. "The second concern is the reliability of the delivery systems. And that issue is being debated between the contractors, SpaceX and the satellite manufacturer, Northrop." While he said he did not know who was to blame, he indicated that the dispute might lead to litigation. "Those two companies are going to have a long and, I suspect, very expensive discussion," he said."

"A network of amateur satellite trackers are on the lookout for Zuma in case it is still in orbit, but they are working off an estimate of its expected location, and it could take weeks to find the spacecraft, assuming it is still in space and is orbiting where predicted."

Pentagon: Ask SpaceX about Zuma. SpaceX: That's not our story to tell, Ars Technica

"Sources familiar with discussions behind closed doors have told Ars there are two primary working theories about what may have gone wrong with Zuma and caused it to burn up in Earth's atmosphere. One idea, in contradiction to SpaceX's official statements, is that the rocket's upper stage underperformed and caused the problem. However, at this time, it seems more likely that the mechanism built by Northrop Grumman to release the satellite failed to operate properly."
