The Delft University of Technology in the Netherlands successfully launched and deployed a 3U Cubesat called "Delfi-C3", into polar low-Earth orbit. Because it carries no batteries, it only operates when not in eclipse. We on the West coast of the United States, and those in Alaska, were the first ones able to hear it. I was unable to hear it on its first pass at around 0455 UTC (2155 local), but they encouraged me to try again for the second pass, at around 0631 UTC. I finally heard it at 06:39:08 (give or take a second or two). (Pictures of the satellite.)
I had almost given up, when I remembered to try the backup frequency, and voilà! There it was! I was able record audio (received by an ICOM IC-R1500 connected to my Mac via USB, recording into QuickTime Player at the device-native format) and send it to the team.
And I just got off the phone with Wouter! He called me to thank me for sending them the audio file, and to tell me that it was, in fact, Delfi-C3, and that I am the first person to hear it. He says this confirms that it is operating in Science mode on the backup frequency. Sadly, it appears that my recording was too noisy to allow any telemetry to be decoded.
What a rush! I'm so thrilled for those guys, and thrilled to have suddenly been a real, if small, part. Wouter tells me they are all very happy to hear that their satellite is alive and well.
Congrats, guys!
