Using the Dwingeloo radio telescope (which predates spaceflight!) we are tracking the carrier frequency of #Artemis II. Maneuvers cause slight changes in that frequency. We annotated the timestamps of Day 1's proximity operations demonstration and we are measuring velocity changes of just a few m/s!
Ships engineer on oceangoing tugs in my past career and now working as maritime technical lecturer and instructor at a University of applied science on Terschelling, the Netherlands.
