Anatomy Of Empirical Transit Spectra Of Mars Based On TGO/NOMAD
Transit spectroscopy is a powerful tool for probing atmospheric structures of exoplanets. Accurately accounting for the effects of aerosols is key to reconstructing atmospheric properties from transit spectra, yet this […]

A 3D Model Simulation Of Hydrogen Chloride Photochemistry On Mars: Comparison With Satellite Data
HCl was detected in the Martian atmosphere by the NOMAD and ACS spectrometers aboard the ExoMars TGO. Photochemical models show that using gas-phase chemistry alone is insufficient to reproduce these […]

ExoMars Observes Water Frost On The Caldera Floor of the Ceraunius Tholus Volcano
Researchers have discovered frost atop volcanoes near Mars’s equator for the first time – a part of the planet where it was thought impossible for frost to form. The finding […]

Newfound Frost Atop The Martian Volcano Olympus Mons
This high-resolution image shows newly discovered frost at the top of Olympus Mons, the tallest volcano not only on Mars but in the entire Solar System. The frost appears blue […]
