Today marks one year since the Air Force's X-37B secret robotic space plane last launched into space, as Spaceflight Now notes. It is still there, doing the secret things a robot space plane does. Things like test a new ion engine and maybe track other space stations. It's spent 15 months and longer in orbit before, doing secret space stuff, so we can expect it to spend some more time there doing secret space things secretly. Because this is the world we live in, now.

The conference's details remain a secret -- Amazon hasn't even confirmed it yet. But Bloomberg says the guests attended seminars, including one that talked about giving robots human values. Amazon focused on these particular fields, most likely because they're all relevant to its interests. It has robots working in its warehouses, and it even held a robotics challenge last year to develop machines that can find items and fulfill orders. Its Amazon Echo speakers come with Alexa, its voice assistant that can read ebooks aloud, control the lights and give you election updates.
