New Autonomy Upgrades Boost Curiosity Rover’s Mars Exploration

Through task consolidation plus autonomous shutdowns, Curiosity stretches its fading nuclear power to probe ancient boxwork formations for signs of past habitability.

Overview

  • Curiosity now performs driving, data relay to orbiters and robotic arm operations simultaneously under new autonomy protocols.
  • An autonomous napping mode lets the rover power down early when tasks finish ahead of schedule, conserving energy for future activities.
  • Engineers have deployed software fixes for wheel wear, a drill rework and a camera filter workaround to counter mechanical degradation.
  • The rover is actively studying boxwork ridges on Mount Sharp, which formed from ancient groundwater and could reveal former subsurface microbial habitats.
  • These upgrades optimize output from the multi-mission radioisotope thermoelectric generator, extending Curiosity’s mission into a 13th year of scientific exploration.
