Diagnostic activities performed by Spirit on Thursday, Jan. 29 narrowed the range of factors that may have contributed to its unexpected behavior earlier in the week. No clear explanation has been established yet. Spirit is healthy and responding to commands. It recorded and returned images of nearby scientific targets. The rover team plans further diagnostics on Friday of Spirit’s inertial measurement unit — a combined gyroscope-and-accelerometer device that measures rover movements and attitude. Spirit may resume driving over the weekend.
