PARIS (ESA PR) — A new map of Mars is changing the way we think about the planet’s watery past, and showing where we should land in the future.

The map shows mineral deposits across the planet and has been painstakingly created over the last decade using data from ESA’s Mars Express Observatoire pour la Mineralogie, l’Eau, les Glaces et l’Activité (OMEGA) instrument and NASA’s Mars Reconnaissance Orbiter Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) instrument.

Satellites Improve National Reporting of Greenhouse Gases

PARIS (ESA PR) — With the climate crisis continuing to tighten its grip, nations around the world are making efforts to reduce emissions of climate warming gases. To track action, countries report their greenhouse gas emissions to the UNFCCC – the body responsible for driving global action to combat climate change. While accurate and consistent reporting is crucial, very few countries exploit Earth observation satellite data to check and improve their estimates. Scientists have now devised new ways of comparing national greenhouse gas inventories with independent measurements taken from space.
