The European Space Agency (ESA) operates Mars Express and ExoMars Trace Gas Orbiter in Mars orbit.
The ExoMars Trace Gas Orbiter delivers high-quality images and comprehensive mapping of atmospheric gases and surface water sites.
A feature image captured by the ExoMars Trace Gas Orbiter covers nearly six square kilometers and was taken on December 24, 2023, at 7.1 degrees south latitude and 173.4 degrees east longitude.
The ExoMars Trace Gas Orbiter continues to monitor Mars to study its ancient past and potential habitability.
The ExoMars Trace Gas Orbiter imaged 3I/ATLAS and detected a coma as the icy object outgassed.
The ExoMars Trace Gas Orbiter has delivered striking surface images of Mars.
Since beginning operations in 2018, the ExoMars Trace Gas Orbiter has mapped water-rich sites and catalogued atmospheric gases.
The new limb observations from the CaSSIS camera add another dimension to the contributions of the ExoMars Trace Gas Orbiter.
The ExoMars Trace Gas Orbiter used its Color and Stereo Surface Imaging System to take a series of digital images of the 3L/ATLAS interstellar object.
The ExoMars Trace Gas Orbiter and Mars Express had the closest view of comet 3I/ATLAS of all spacecraft.
On 3 October, the ExoMars Trace Gas Orbiter turned its camera towards interstellar comet 3I/ATLAS as it passed close to Mars.
The ExoMars Trace Gas Orbiter observed the comet from just 30 million km away during its closest approach to Mars.
Mars Express and ExoMars Trace Gas Orbiter will observe the comet 3I/ATLAS around its closest approach to Mars on 3 October 2025.
Olsen uses ESA's ExoMars Trace Gas Orbiter and its Atmospheric Chemistry Suite to probe Mars's atmosphere.
ESA’s ExoMars Trace Gas Orbiter used aerobraking operationally in 2017 to lower its orbit around Mars over an 11-month period.
