=== Mars exploration ===
The 1990s and 2000s saw a resurgence in [[Mars]] exploration, driven by JPL's [[Mars Pathfinder]] and [[Mars Exploration Rover]] missions.<ref>{{Cite book |last1=Wright |first1=J. |last2=Trebi-Ollennu |first2=A. |last3=Hartman |first3=F. |last4=Cooper |first4=B. |last5=Maxwell |first5=S. |last6=Jeng Yen |last7=Morrison |first7=J. |title=2005 IEEE International Conference on Systems, Man and Cybernetics |chapter=Terrain Modelling for In-situ Activity Planning and Rehearsal for the Mars Exploration Rovers |date=2005 |volume=2 |pages=1372–1377 |chapter-url=http://dx.doi.org/10.1109/icsmc.2005.1571338 |publisher=IEEE |doi=10.1109/icsmc.2005.1571338 |isbn=0-7803-9298-1 |s2cid=11275990 |access-date=August 5, 2023 |archive-date=May 23, 2024 |archive-url=https://web.archive.org/web/20240523065252/https://ieeexplore.ieee.org/document/1571338/ |url-status=live }}</ref> In 1997, the Mars Pathfinder mission deployed the first successful Mars rover, ''[[Sojourner (rover)|Sojourner]]'', demonstrating the feasibility of mobile exploration on the Martian surface. In 2004, the Mars Exploration Rovers, ''[[Spirit (rover)|Spirit]]'' and ''[[Opportunity rover|Opportunity]]'', landed on Mars. ''Opportunity'' outlived its expected lifespan by 14 years, providing a wealth of scientific data and setting the stage for future Mars missions.<ref>{{Cite journal |last1=Konopliv |first1=Alex S. |last2=Park |first2=Ryan S. |last3=Folkner |first3=William M. |date=2016 |title=An improved JPL Mars gravity field and orientation from Mars orbiter and lander tracking data |url=http://dx.doi.org/10.1016/j.icarus.2016.02.052 |journal=Icarus |volume=274 |pages=253–260 |doi=10.1016/j.icarus.2016.02.052 |bibcode=2016Icar..274..253K |issn=0019-1035 |access-date=August 5, 2023 |archive-date=May 23, 2024 |archive-url=https://web.archive.org/web/20240523065311/https://www.sciencedirect.com/science/article/abs/pii/S0019103516001305?via%3Dihub |url-status=live }}</ref>
