Material cited and its limits
USGS LIMA orbital coverage statement — This product-specific 82.5°S coverage limit cannot be generalized to all imagery.
Research context
Original Landsat LIMA coverage stops at 82.5°S because of its orbital coverage. That product-specific limit does not describe every satellite or establish censorship in a particular Google Earth patch.
Read the cited research contextThe USGS research publication describes LIMA scenes acquired primarily during 1999–2003, combined and processed into a mosaic. Publication date and observation date are different.

NASA/JPL-Caltech/UC Irvine / Ice-shelf context / Context image—not proof of the broader claim.
Image rights and evidence limits
Image existence does not prove a linked claim. Consult image-specific captions and reuse conditions.
Sources and what they support
Links document the record, the claim’s circulation, an assessment, or reuse terms as labeled. A source link is not automatically corroboration.
