The Mars Exploration Rover Opportunity gives us this “selfie”. Okay, so it’s the rover’s shadow, it still counts if you are on Mars because there’s no mirrors.
The image was taken on the 3,609th day on the surface of Mars! That would be 20 March 2014 here on Earth.
Here’s the press release – you can get larger versions at the link too:
NASA’s Mars Exploration Rover Opportunity caught its own silhouette in this late-afternoon image taken by the rover’s rear hazard avoidance camera. This camera is mounted low on the rover and has a wide-angle lens.
The image was taken looking eastward shortly before sunset on the 3,609th Martian day, or sol, of Opportunity’s work on Mars (March 20, 2014). The rover’s shadow falls across a slope called the McClure-Beverlin Escarpment on the western rim of Endeavour Crater, where Opportunity is investigating rock layers for evidence about ancient environments. The scene includes a glimpse into the distance across the 14-mile-wide (22-kilometer-wide) crater.
I was having a look at the ESA Space in Images page and they had this image of the stormy atmosphere of Saturn. We tend to be more used to seeing this sort of activity in the atmospheric bands of Jupiter, Saturn shares similar storm processes (and banding) although the colors tend to be more muted. The image colors were enhanced to tease out the visual details as explained below in the ESA caption.
Like a swirl from a paintbrush being dipped in water, this image from the Cassini orbiter shows the progress of a massive storm on Saturn. The storm first developed in December 2010, and this mosaic captures how it appeared on 6 March 2011.
The head of the storm is towards the left of the image, where the most turbulent activity is shown in white, but towards the centre you can also see the trace of a spinning vortex in the wake of the storm.
This image, centred at about 0º longitude and 35º N latitude, has had its colours enhanced to help reveal the complex processes in Saturn’s weather. The white corresponds to the highest cloud tops, but to the human eye the storm would appear more as a bright area against a yellow background. Continue reading →
