SpaceX is hoping to launch "Zuma" into orbit via one of the company's Falcon 9 rockets this week after nearly two months of delays. What exactly Zuma is, though, is still a big secret.

Northrop Grumman confirmed to me in November that it had contracted with Elon Musk's commercial space venture to do the launch on behalf of a US government agency, which it didn't name. It provided no other details about the payload.
