Clever comms
When I first read about the new downlink capability I first thought that it would be a) hard and b) limited to when they were in range of the ground stations - given the every-90 minute orbit, that's probably quite frequent. Then discovered that it was even more impressive - the antenna isn't broadcasting down to earth, it's broadcasting *up* to the geostationary EDRS satellites instead. I continue to be blown away by science and our ability to come up with ingenious solutions.
