MUMBAI (TIP): Curiosity has resumed science investigations and returned to active status following two days in a precautionary standby status, “safe mode,” Nasa announced on Wednesday. The next steps will include checking the rover’s active B-side computer, by commanding a preliminary free-space move of the arm. The B-side computer was provided information last week about the position of the robotic arm, which was last moved by the redundant A-side. The rover was switched from the A-side to the B-side on February 28 in response to a memory glitch.
