We've had a productive first two days at the Canadian Space Agency testing our methane-hunting scenario. The rover drove to many locations on the Mars Emulation Terrain and gathered measurements from an active spectrometer, which bounces a laser off retroreflectors, to try to locate a hidden source of methane. Tomorrow we'll switch over to a passive spectrometer scenario where we'll be using the sun as a light source (instead of bouncing a laser off a retroreflector).
