So, 3% memory damaged. Okay fine, so move the affected programs around to avoid that region. The amount of work on the FDS's plate has presumably been dwindling as instruments got shut down, so there's space?
Well, sort-of. First order of business is to relocate and fix the EL-40 program, which assembles engineering data into the low bitrate EL-40 telemetry format, so the team can get a look at what all else is going on.
There's space in the memory to relocate, but not contiguous.

So, the plan turned into: okay, we'll move the EL-40 program to _several_ new regions of memory, and patch up the code so that it all still works right. So, uh, yeah, that's re-linking the binary that tells you if the spacecraft works, while the spacecraft is a little under a light-day away from earth, with a 45 hour round-trip time.
