The objective of this observation is to determine the nature of a group of mounds, some of which have small pits at their summits. These features may be caused by ground ice melting and possibly turning into steam. They are barely visible in Context Camera image, so our camera’s resolution can help us to determine how they were formed.

NASA's Mars Perseverance rover acquired this image using its onboard Left Navigation Camera (Navcam). The camera is located high on the rover's mast and aids in driving.

This image was acquired on Oct. 5, 2026 (Sol 2000) at the local mean solar time of 10:03:40.

​SUPER Conditions as Southern California's dry heatwave continues and brings with it some amazing seeing even at less than 40 degrees up. I was determined to get this shot and it was not easy but I pulled it off. If the target was higher I think it could have been more clear. I resized this image to 2500x2500 from roughly 300x300.

.

​HOW I DID THIS IMAGE:

Keeping my histogram at 30%. This keeps the Moons from blowing out. I focus the Moons. FPS 250 I shot consecutively 30 second shots and this is the maximum shot. You can appreciate how Io is in fact moving fast against Ganymede's surface background. This is because Io orbits much faster. On this capture, Io would appear to be the only one moving and both moons are moving in opposite directions.

Watching the sun is watching a magnetic field in action. Those fun science experiments we did in school with iron filings and a magnet is basically what we are seeing on the sun, but with more complexity.

The sun does not have one single north south magnetic poles, but many different ones scattered all over at varying strengths.

We can see how magnetism governs the churning atmosphere known as the chromosphere. A relatively thin layer where hydrogen alpha particles can be seen interacting with the fields being generated.
