Apollo 17 and Landsat

A new addition to my exploration of Apollo imagery: Landsat.

The first Landsat satellite was launched in July 1972, and there are several dates in the Apollo 17 mission where image paths taken by it coincide with Apollo 17 photographs of Earth. Landsat images are available via the earthexplorer website https://earthexplorer.usgs.gov/ where you can download kmz files to import into Google Earth, from which you can then download higher resolution imagery. I've compiled the individual tiles into longer paths so that they can be compared with Apollo 17's Earth imagery.

As the Earth becomes increasingly distant the two data sets become difficult to reconcile thanks to Earth being out of focus, at odd angles, photographed many hours after Landsat, or just too distant, but in the early stages of the mission there are some fantastic comparisons to be made.

Here are a few of the best - I particularly like the 'Blue Marble' view of Antarctica :)

AS17-148-22685 - East African Coast



AS17-148-22686 - Eritrea & Ethiopia



AS17-148-22725 - Indian Ocean



Mawson Coast (Antarctica)



AS17-148-22743 - Antarctica



South Africa

I decided to check if any other photographs of Antarctica showed the 'Blue Marble' ice flows in any greater detail and was rewarded with AS17-148-22717:



Everything matches beautifully :)

Yup can also make out the area on AS17-148-22685, but it's at a much more oblique angle.

Doesn't this show Africa?

It does, but there's a sliver of Antarctica in the bottom right corner.

Ok, I enlarged the magnification and do see the ilet of Anartica.
I've said many times, your eyesight is much better at finding those shapes than I.  Cudos.
