I wish I hadn't made this - it's grim. STFC Ernest Rutherford Fellowship success rates over time. I found conflicting data on the STFC website, so there could be a mistake, but last year the success rate was <4%
A plot showing 3 lines, over the time period of 2014 to 2025. Applications have risen from 166 to 186. Funded applications has decreased from 12 to 7. And so success rates have decreased from 7.2 to 3.8%.

My talk at #BPSC2026 is showing our study of active dust devils at the ESA Rosalind Franklin rover landing site. Take home message: although they are difficult to see, we found 37 active dust devils. But... We predict a clearing event once every ~4000 sols. Which, er, isn't great for solar power!

I’ve worked at @nhm-london.bsky.social for a while now, and yet still have my mind blown on a regular basis. Today, 2 rocks from the collection: Fulgurite (created by a lightning strike) collected by Charles Darwin. Fossil leaf collected by Robert Falcon Scott (on the Terra Nova expedition).
Photo of a plastic case containing small samples of a few small grey rocks, which have linear-like structures. An old sample label reads “Fuglurite (lightning tube). Maldonado, Uruguay. Collected by Charles Darwin and described by him in ‘A Naturalist’s Voyage’”.Photo of a grey rock with some dark, almost black features, which are the remains of a now fossilised plant leaf.

The atmosphere of Mars is too thin to effectively shield it from small meteors hitting the surface. Here, a new, small (10 m) impact crater formed some time between 2010 and 2019. Although the crater is small, the effects are widespread, with the seismic energy triggering lots of dust falls!

Some parts of Mars really do change a lot between images. Here are 2 CTX images of exactly the same region taken about 7 years apart (Dec 2007 - Jan 2015). Lots of dust devil tracks, and wind streaks. But also, a new impact crater.

Mars is a colourful planet part 73... Here is part of Oxia Planum (landing site for ExoMars Rosalind Franklin rover) seen by CTX (1 band) and CaSSIS (4 bands) cameras. The image is 'false colour', as it is not how our eyes would see it. But the colour is really useful as a proxy for composition.
