K2 Tuesdays is a semi-regular series on the development of KySat-2, the latest spacecraft from Kentucky Space. Prior installments are here, here, here, here, here, here, here, here, here and here.

On Friday March 29th the students at the Space Systems Lab at the University of Kentucky held their second “code-pocalypse”. This session, like the first, was done to allow the students to work unencumbered for a few hours and code the different portions of the flight software while in the same room. This was the first event using the software team's new flight model command and data handling (C&DH) system (below, right) as opposed to the previous development version of the hardware.

The chief accomplishment of the event was that the C&DH successfully received instructions from the radio to take a picture, then carried them out and stored the data on its (the C&DH’s) native storage.

Attached is a screenshot showing our code running.  In it, our "gather beacon" command runs every seven seconds to update the telemetry contents of our beacons (electrical power system telemetry, temperatures, mission time, etc.).  Then, at 19 seconds, we sent a radio command to take a photo, scheduled to execute at 30 seconds. At 30 seconds, you can see that the command to take the photo was sent.

As mentioned in the recent video update, the KySat-2 team is building the "flatsat" version of KySat-2 with the 3D printed model of the spacecraft. We expect the aluminum structure to arrive in the next 10 days or so. All the physical components are coming together nicely.

Morehead State Students will be heading to the UK campus this week for thermal vacuum testing of some equipment they’ve build for a different mission. More on that testing and the flatsat in the upcoming K2 Tuesdays.
