WhoIsAtMarsToday? is a website inspired by How Many People Are In Space Right Now?, listing the robots currently operational on the surface of, and on orbit around, Mars.
A future enhancement will be to automatically update WhoIsAtMarsToday? daily via crowdsourced data. This data will likely be scraped from Wikipedia's List of Missions to Mars, and parsed using wtf_wikipedia.
