He was meeting someone (else) from the train. I was too shellshocked/awkward to do anything but stare dumbfounded.
An image of the surface of Mars, where a landslide deposit runs top to bottom. Streaks of colours (blues, cyans) stretch through the landslide.
Do other people have a favourite landslide?
If not, consider adding this one on Mars. The colour from the CaSSIS instrument is just amazing.

This is what a dust storm on Mars looks like.
As seen by the Curiosity rover in 2018. Images taken over nearly a month, with roughly the same view.

The origins of more than 15,000 mysterious mounds on the red planet have been revealed, having been carved out of the surface by water billions of years ago.

Fantastic news! And so well deserved!
Giulia is an amazing scientist and the best colleague.
It's a commonly-used phrase for an image that is real 'colour', but isn't as the human eye would see it.
In this case, RGB colours correspond to near-infrared (940 nm), red (678 nm), and blue (495 nm) wavelengths.

It was the second largest lake in the country, but is now unlikely to return. Caused by climate change and diversion.

Say hello to the Sol 1034a impact crater, the nearest one to InSight.
It was a tough one to find in images. Only 9 m in diameter, but has made over 900 secondary craters!
NASA has recently released updated websites for data!

Trying to clear up the view a little bit.
Upscaled, stretched colour, sharpened, removed vignette...
Grab your red/blue glasses, and have a look at part of the view in 3D!
Only NavCam images available so far, but this is lovely.
As the Perseverance rover reaches the edge of Jezero crater, and the view beyond begins to open up, these two fantastic websites might help you explore this amazing part of Mars:

I had the different terms drummed into me recently on an umpiring course...
"A cricket pitch consists of the central strip of a cricket field between the two wickets."
Of course, everyone (me included) uses all those terms however they want!
