TL;DR
NASA’s Jet Propulsion Laboratory is successfully maintaining the Curiosity rover on Mars after 13 years through continuous software updates and engineering efforts. The rover remains scientifically productive despite aging hardware and wear.
NASA’s Jet Propulsion Laboratory (JPL) continues to operate the Mars rover Curiosity after 13 years, using software updates and engineering strategies to sustain its mission despite hardware aging and environmental challenges.
Curiosity landed on Mars in August 2010 and has since traveled nearly 37 kilometers, drilled into 42 rocks, and captured over 763,000 images. Despite its age, the rover remains active and productive, thanks to ongoing software updates, careful hardware management, and innovative problem-solving by JPL engineers.
Alexandra Holloway, assistant team chief for engineering operations at JPL, explained that the longevity of Curiosity results from continuous efforts to maintain and adapt its systems. Notably, the team has performed complex software fixes, such as reconfiguring onboard computers and managing memory anomalies, to keep the rover operational. The rover’s hardware, including its RAD 750 processor, has proven remarkably durable, though wheel wear and decreasing power output from its nuclear RTG are ongoing concerns.
Despite these challenges, JPL engineers have kept Curiosity functioning, with some modifications allowing it to perform science and driving tasks. The team is also applying lessons learned from Curiosity to newer missions, like Perseverance, which benefits from more advanced onboard autonomy and hardware improvements.
Sustaining Long-Term Mars Missions Through Engineering
The ability to keep Curiosity operational after 13 years demonstrates the success of engineering strategies in extending the lifespan of robotic explorers in harsh environments. This achievement provides valuable insights for future planetary missions, emphasizing the importance of software flexibility, hardware resilience, and adaptive problem-solving in space exploration.
Moreover, Curiosity’s continued scientific work enriches our understanding of Mars’ geology and climate, contributing to ongoing efforts to assess the planet’s habitability and search for signs of past life. Its longevity also showcases the potential for cost-effective, long-term robotic missions that can adapt and evolve over time, maximizing scientific return.

Development and Maintenance of Curiosity Over the Years
Launched in 2011 and landing on Mars in August 2012, Curiosity was built with robust hardware designed for a two-year primary mission. Over time, it has exceeded expectations, traveling nearly 37 km and conducting extensive scientific investigations. The rover’s longevity is partly due to the use of a RAD 750 processor, similar to those in older aerospace systems, which has proven reliable in the Martian environment.
JPL engineers have faced challenges such as wheel wear from sharp rocks and decreasing power from the nuclear RTG, which diminishes output over time. They have responded with software updates, hardware reconfigurations, and operational changes, such as driving backwards to reduce wheel damage. The team also performed a notable software fix called “R-Hope,” repurposing memory to keep the rover functioning with limited resources.
This ongoing maintenance has allowed Curiosity to continue its science mission, providing data that informs NASA’s broader exploration goals, including preparing for crewed missions to Mars.
“The longevity of Curiosity comes from continuous effort—software updates, hardware management, and problem-solving. It’s astonishing how resilient this rover has been.”
— Alexandra Holloway, JPL engineer
