Topic: Washington University in St. LouisWritten by Guy Webster
The scene includes a broad notch in the crest of the crater’s rim, which may have been a spillway where water or ice or wind flowed over the rim and into the crater. Wheel tracks visible in the area of the notch were left by Opportunity as the rover studied the ground there and took images into the valley below for use in planning its route. ![]() This June 2017 view from the Pancam on NASA’s Opportunity Mars rover shows the area just above “Perseverance Valley” on a large crater’s rim. A broad notch in the crest of the rim, at right, might have been a spillway for a fluid that carved the valley, out of sight on the other side of the rim.

NASA’s Mars Opportunity Rover leaves Cape Tribulation heading for Perseverance Valley on MarsWritten by Guy Webster
The rover team plans observations in the valley to determine what type of fluid activity carved it billions of years ago: water, wind, or flowing debris lubricated by water. A color panorama of a ridge called “Rocheport” provides both a parting souvenir of Cape Tribulation and also possible help for understanding the valley ahead. The view was assembled from multiple images taken by Opportunity’s panoramic camera. ![]() A grooved ridge called “Rocheport” on the rim of Mars’ Endeavour Crater spans this scene from the Pancam on NASA’s Mars rover Opportunity.

NASA’s New Horizons spacecraft shows activity on the surface of PlutoNASA Headquarters
Transmitted to Earth on December 24th, this image from the Long Range Reconnaissance Imager (LORRI) extends New Horizons’ highest-resolution views of Pluto to the very center of Sputnik Planum, the informally named icy plain that forms the left side of Pluto’s “heart” feature. ![]() Transmitted to Earth on Dec. 24, 2015, this image from the Long Range Reconnaissance Imager (LORRI) extends New Horizons’ highest-resolution swath of Pluto to the center of Sputnik Planum, the informally named plain that forms the left side of Pluto’s “heart.” Mission scientists believe the pattern of the cells stems from the slow thermal convection of the nitrogen-dominated ices.

NASA’s New Horizons spacecraft finds active Ice Flows on PlutoNASA Headquarters
“We’ve only seen surfaces like this on active worlds like Earth and Mars,” said mission co-investigator John Spencer of SwRI. “I’m really smiling.” ![]() New Horizons discovers flowing ices in Pluto’s heart-shaped feature. In the northern region of Pluto’s Sputnik Planum (Sputnik Plain), swirl-shaped patterns of light and dark suggest that a surface layer of exotic ices has flowed around obstacles and into depressions, much like glaciers on Earth.
