  • I think the most surprising part of all of this is that it hit over 20* positive pitch, that seems like a lot and a bit risky?

    I believe it’s well inside the design tilt limits, however I’m unable to locate the actual reference at this time. The highest end-of-drive pitch by Curiosity was on Sol 2692, the pitch was +28.51°, which provided a maximum tilt of +29.12°. IIRC that tilt was exceeded mid drive when it was climbing onto a ridge earlier in the mission. Tilt fault protection is enabled by default during each drive, and the nominal flight tilt limit is 30°. However, the tilt limit is typically lowered by the Rover Planners for each drive or drive segment, based on the maximum predicted tilt experienced in the simulation of the planned drive. If I can find the reference docs, I’ll add another reply.
