Context examples:
In some of the years when no orbiter was observing Mars up close, Mars was poorly positioned for Earth-based telescopic detection of dust storms during the Martian season when global storms are most likely.
(Study Predicts Next Global Dust Storm on Mars, NASA)
A link between the presence of water vapor in Mars' middle atmosphere — roughly 30 to 60 miles (50 to 100 kilometers) high — and escape of hydrogen from the top of the atmosphere has been detected by NASA's Hubble Space Telescope and the European Space Agency's Mars Express orbiter, but mainly in years without the dramatic changes produced in a global dust storm.
(Dust Storms Linked to Gas Escape from Mars Atmosphere, NASA)
A set of three observations with the orbiter's High Resolution Imaging Science Experiment (HiRISE) camera shows Beagle 2 partially deployed on the surface of the planet, ending the mystery of what happened to the mission more than a decade ago.

Composed of an orbiter and lander, Rosetta's objectives upon arrival at comet 67P/Churyumov-Gerasimenko in August are to study the celestial object up close in unprecedented detail, prepare for landing a probe on the comet's nucleus in November, and track its changes as it sweeps past the sun.

Even with more detailed studies of Martian meteorites coupled with thermal imaging of Mars taken from orbiters, and rock samples analyzed by rovers traversing the planet's surface, the best evidence of Mars' water history would be an actual Martian rock taken from the planet and transported back to Earth, intact, for detailed studies.
(New Evidence for A Water-Rich History on Mars, The Titi Tudorancea Bulletin)
The authors of the new paper make use of data from two of those spacecraft, NASA's Mars Reconnaissance Orbiter (MRO) and Mars Odyssey orbiter, to locate water ice that could potentially be within reach of astronauts on the Red Planet.
(NASA's Treasure Map for Water Ice on Mars, NASA)
Scientists taking a new look at older data from NASA's longest-operating Mars orbiter have discovered evidence of significant hydration near the Martian equator — a mysterious signature in a region of the Red Planet where planetary scientists figure ice shouldn't exist.
(A Fresh Look at Older Data Yields a Surprise Near the Martian Equator, NASA)
For instance: Opportunity, as a solar powered rover, would have to hunker down to save energy; the upcoming InSight lander's parameters would need to be adjusted for safe entry, descent and landing in November; and all the cameras on rovers and orbiters would need to deal with low visibility.
