Did you know that Seasat collected SAR data as well as radar altimetry in 1978? Available for download at

For many years, the SAR data from Seasat was locked away on tapes and film strips, but it was added to the Alaska Satellite Facility archive on the 35th anniversary of the mission in 2013 and made available online.

Including this image of Mt St Helens less than 2 years before it erupted in 1980.

One more random Seasat find: a print of an artist's conception of Seasat from 1974. I believe the solar panel configuration is different from the final one (or at least all the other diagrams I've seen):
