How the 14 ASCII characters per node are encoded into the record groove.

Each message frame begins with an 8-bit Barker sequence [11100010] for frame synchronization.
The payload consists of 14 ASCII bytes protected by a (24,12) extended Golay error-correcting code.

When all 14 rows are assembled, the matrix forms an 80-column ASCII status report.

The song wasn't written around the lyrics. The lyrics were timed to match the telemetry packet duration!

Netscape 1.1 crashes when loading large preformatted text. Stick to rn or tin!
