I was going to post a snarcy comment along the lines of so they've hooked a fax to an acoustic coupler and invented Radio-Fax but thought I should perhaps do 5 or 6 seconds of research first.
It seems from the 1930's to 1970's there was a system called "Radio-Fax" which was indeed the precursor of SSTV.
Anyway always good to see stuff from space anybody can access.
