19. Sojourner

20. According to NASA, Sojourner landed on Mars on 4 July 1997 and lost communications on 27 September 1997. The rover weighed 10.6 kilograms and carried instruments for scientific observations and technology demonstrations. It traveled just over 100 meters before communications ended. NASA records that observations from Mars Pathfinder and Sojourner suggested that ancient Mars had been warm and wet. NASA states that rounded pebbles and cobbles observed by Pathfinder suggested that they had formed in running water during a warmer period. NASA managed Sojourner through its Jet Propulsion Laboratory.

Opportunity drove 45.16 kilometers, although it was designed for 90 Martian days, and operated for more than 15 years. NASA records that it found evidence that liquid water had existed on ancient Mars, and its findings indicated that Meridiani Planum may have been habitable during part of Mars's history. NASA also reported that Opportunity returned more than 217,000 images, exposed the surfaces of 52 rocks, and brushed 72 additional targets.

31. NASA reported on 10 September 2025 that the Sapphire Canyon sample collected by Perseverance contained potential biosignatures that required further study before conclusions about life could be reached. Spots in the Cheyava Falls rock carried signatures of vivianite and greigite. NASA stated that these minerals could also form without biological processes, while reporting that abiotic explanations were less likely but could not be ruled out for the Bright Angel formation. Perseverance had collected 27 rock cores by 10 September 2025.

Sources give different dates for the event: one source reports 20 May 2022, while another reports 18 May 2022. A 2023 report stated that dust on its solar panels had prevented sufficient energy from reaching the rover for a restart. CNSA scientists had not received a signal from Zhurong by January 2023, and the rover had not changed position between September 2022 and 21 February 2023.

    With a sandstorm and the Martian winter approaching, Zhurong entered hibernation in May 2022. Sources disagree on the date: one gives 20 May 2022, another 18 May 2022. A 2023 report said dust on its solar panels had kept enough energy from reaching the rover for it to restart. CNSA scientists had received no signal from Zhurong by January 2023, and the rover had not changed position between September 2022 and 21 February 2023. In April 2023, mission designer Zhang Rongqiao said Zhurong's dust accumulation had exceeded expectations and the rover might remain permanently inactive.
