I'm assuming live telemetry from a satellite. The part I was curious about is, in the message emulator, sending the message seems to take a really long time for a round trip. So it looks like it must be pretty far away from Earth.

Little search shows that that it's a probe sent to an asteroid to collect samples and bring them back to Earth. It was sent in 2014, arrived this year, and will fly back in 2019 and arrive in 2020.

EDIT: Looks like it just landed on the asteroid, hence this being posted [0]

Appears to be communications from an asteroid probe to grab samples and return those samples to earth. [1]
