I’m a geologist who now works mostly on other worlds, and the one that is keeping me busiest at present is Mercury. This is the closest planet to the Sun, which means that is always much closer to Earth than Jupiter ever gets.

However, it is harder to study because the Sun’s glare makes it difficult to observe with telescopes, and the Sun’s gravity poses an enormous challenge if you want to get a spacecraft into orbit about Mercury.

NASA achieved this with its MESSENGER orbiter (2011-2015), and I’m on the science team for the European Space Agency’s BepiColombo orbiter 2024-2025, due for launch in later 2016.

Code-breaking challenges

Late last year, pupils from St Paul’s Catholic School in Milton Keynes gathered only 3 miles away from Bletchley Park, where Alan Turing famously cracked the Enigma code during the Second World War, to take part in their own code-breaking challenge.

Small teams of Year 9 pupils battled it out in a series of tasks requiring them to decrypt secret messages as quickly as possible.

The event was organised by me and my fellow Open University maths PhD student and STEM Ambassador, David Martí Pete. We were aiming to give pupils a broader sense of what maths is really about: solving problems.
