This month has seen missions large and small launch towards Mars, and new results from the Gaia satellite. Meanwhile, astronomers have been using machine learning to address a number of problems \u2013 we discuss a couple of examples which have been published recently. Finally, there have been exciting new signs of plumes from Europa, one of Jupiter\u2019s moons \u2013 something that future missions might be able to explore in more detail.
