Sweet (Two Thousand and) Sixteen

Is it really only a month or so since I last wrote?! Christmas break aside, so much has happened that I thought it must have been a lot longer! Time is sprinting faster and faster as iMars and Mars in Motion grow. Since I last updated you, the European Geosciences Union has published a blog post I wrote for them that I point you to here for continuity. Some of it might have repeated what I have already said here, but I am happy and grateful for having had the opportunity to introduce myself to a different, but no less potentially interested, audience.

December started with the Geological Remote Sensing Group meeting  at the European Space Agency (ESA)‘s European Space Research Institute in Frascati, Italy. I was especially happy to be reunited with some of my friends from University College London. I was also grateful to present my talk early in the meeting so that I could relax for the rest of my time there and those there recognised me as ‘Miss Mars’ and I didn’t spend the week explaining myself! A superb range of presentations allowed me to play a very successful round of ‘Buzzword Bingo‘ with Change Detection, Big Data and Crowd-sourcing; presentations that struck a chord included those by Alex Gow from DigitalGlobe who recounted the use of Tomnod for voluntary validation and extraction of features on the ground in remote sensing imagery to inform relief efforts in the aftermath of the Nepal Earthquake, and Alex Tewkesbury who talked about his paper on the detection of change of change in remote sensing imagery. It was a far more international affair than I had anticipated, and I made some valuable connections with people I would have otherwise never met.

Immediately on my return I was on iMars duty for the second round of experiments. We’re already getting insights into the challenges we will have to overcome to present a change detection task with the crowd sourcing approach, in a way that makes sense to the crowd and the scientists. Somebody asked me in Frascati how I would assess the success of this project and, although the experiments focus on the design of the user interface and task, my dream is still that the crowd-sourced data will produce new insights into the Martian environment, to enhance our knowledge as well as informing missions, and one day train a computer algorithm sufficiently well to detect surface changes automatically. This is the ambition, so it will be interesting to reflect on that this time next year.

We didn’t break for Christmas until we had showcased the project to school children attending the University of Nottingham’s Engineering Faculty Christmas Lecture on the theme of “Light and Sound.” It proved a surprisingly useful opportunity to observe our designs’ impact on fresh eyes, without the silence and unavoidable pressure that experimental conditions can impose. Our potential planetary scientists were keen to work together, rather than on their own, so we engaged in discussions that would ordinarily take place online on forums. For our table’s visitors it became a game of ‘Change or no change?‘ They asked and raised some fantastic questions, which were far more difficult to answer than those at ESA! The difficulty of distinguishing between changes in lighting or image quality and those actually happening on the surface are becoming increasingly clear. It was all worth jumping the last minute technological hurdles that seem sent not only to try us but amuse us on such occasions. The irony of struggling to connect to a network or WiFi to see images that have come all the way from Mars is not lost on us!

Full steam ahead for 2016, during which I intend to write papers rather than do any more space travel. I have a few papers outlined in my head based on what we’ve learned so far and I am just grateful that after my thesis I won’t be writing the papers alone. I also take some comfort and confidence from the prospect of contributing to two upcoming special issues of journals, which suggest I am not alone in my excitement about the potential for my area of research.

But for now, on my agenda for the first working week of the new year? Addressing the final amendments requested to Nottingham’s mid-project reports (against which we are evaluated by the European Commission at the end of the project); preliminary perusal of the responses and comments that participants in our first and second experiments provided, and preparation for the presentation I will give to the rest of the iMars team in Lausanne, Switzerland next week. For now I wish you (and myself!) all the very best for 2016. I will leave you with the belated Christmas present of these images that I recently found for the benefit of our experiment participants, simply because they are too beautiful to keep to myself. They exemplify just some of the features in which the iMars project is looking for changes.
