And in more familiar colours. This is the central peak of an unnamed crater, to the north of Syrtis Major.pic.twitter.com/X5fitjKp6Q

What an image - this is Mars! Near-infrared data from CRISM instrument, showing different compositions at the surface. In this case, yellow = analcime (a zeolite).pic.twitter.com/D9PLgCGUI8

Interested in doing a planetary science PhD about space, rocks, and space rocks, in this amazing building? Then have a look at our
@STFC_matters projects that have just gone up! https://www.nhm.ac.uk/our-science/courses-and-students.html …pic.twitter.com/tryhhh4XRM

Still got a massive grant to help finish writing, so I obviously just animated our

This is my wife’s favourite face rock. She can’t look at it without cracking up for 10 minutes. She’s a professional geologist. https://twitter.com/huw_groucutt/status/1220781593645764608 …pic.twitter.com/rEkDCjLviv

A friend is working in South Georgia for 5 months this austral summer - got giddy seeing this letter arrive! Also, was the postage really only £1.30?!pic.twitter.com/4KSnOP07VA

Grains of martian sand blown by a thin wind on the rim of a crater. Just 5 years of change, imagine what would happen in 5, 50, 500 million years.pic.twitter.com/UE8YEutA6D

When giving a serious science talk, it’s important to dress appropriately. Finally on my way to

And comparing CTX (before) with HiRISE (after). As of yet, I think that we haven't been lucky enough to get a HiRISE before. Anyone know of any?!pic.twitter.com/CwbzpYR0SS

Often,
@HiRISE will then image them at higher resolution and in colour. And the results are spectacular! These craters are only about 3-4 m in diameter, but lots of dust is blasted away. Full image here https://www.uahirise.org/ESP_053653_1850 pic.twitter.com/SJDaf2DAK5

Several hundred impact craters have been seen to form on Mars over the last 15 years or so. Here's 2 that formed together, sometime between 9 March 2014 and 7 January 2016. As seen by CTX instrument on MRO.pic.twitter.com/nNBLRDirsA

And from a different gully in Hale. Lots of boulders moving or being obscured by other material.pic.twitter.com/ceyCEay80U

Mars isn't a dead planet, part 257. Here's one of many active gullies in Hale Crater.

Ok, who’s with me? Having both NASA logos together is wrong. Almost as wrong as charging 80 quid for a hoodie. Also, is that why he’s so angry?pic.twitter.com/gXbYniUMyx

“WHOOOOOSH!” The sound Mars Express makes* as it passes Mars’ north polar cap. AND The sounds my deadlines make* while I mess about with raw images. *no sound really – they are in the vacuum of space or my head, respectivelypic.twitter.com/EzAUFw9Ebh
