It also occasionally relays measurements from Spirit & Opportunity to NASA. Indeed the lessons learned from building and operating Mars Express spawned a sister ship, Venus Express that also still operates in Venusian orbit.

A new study now reveals the extent of underground water on ancient Mars that was previously only predicted by models. Notes for editors"Geological evidence of planet-wide groundwater system on Mars" by Salese, F., Pondrelli, M., Neeseman, A., Schmidt, G., and Ori, G. G. is published in Journal of Geophysical Research – Planets.

ESA’s Mars Express spacecraft has discovered several ponds of liquid water buried under the ice in the south polar region of Mars.

2003 was a great year for Mars exploration as it also saw the dual liftoffs of NASA’s now legendary rovers Spirit & Opportunity from Cape Canaveral in Florida. Salese and colleagues explored 24 deep, enclosed craters in the northern hemisphere of Mars, with floors lying roughly 4000 m below martian ‘sea level’ (a level that, given the planet’s lack of seas, is arbitrarily defined on Mars based on elevation and atmospheric pressure).

While the ExoMars Trace Gas Orbiter is already studying Mars from above, the next mission will launch next year. Keep up with the latest scitech news via email or social media. This series of five maps shows near-global coverage of key minerals that help plot the history of Mars. The techniques used to analyze the radar data on Mars are similar to those used in investigations of subglacial lakes in Antarctica, Canada and Greenland.

#9. Estimation of the current rate of atmospheric escape, helps researchers explain how Mars changed from a warm, wet place to the cold, dry place it is today. Study the martian atmosphere and climate, the planet's structure, its mineralogy and its geology, and to search for traces of water from orbit. Our Book is out! #2. It carried the first ever radar sounder (MARSIS) to orbit another planet and has discovered vast caches of subsurface water ice. But thats a good question to follow up, Join our 836 patrons! The finding adds weight to the idea that these basins on Mars may once have had the ingredients to host life. And More…, Episode 688: Remnants From the Early Universe. Initially, Mars Express also carried a small lander called Beagle 2, named for the ship in which Charles Darwin set sail to explore unchartered areas of the Earth in 1831. “We think that this ocean may have connected to a system of underground lakes that spread across the entire planet,” adds co-author Gian Gabriele Ori, director of the Università D’Annunzio’s International Research School of Planetary Sciences, Italy.

27:03 OSIRIS-REx update Mars was once warmer and wetter with water flowing across the surface, much like early Earth. #3. 54:47 Have any black holes evaporated yet? A digital terrain model was used based on data from the HRSC and NASA’s Mars Orbiter Laser Altimeter. Unambiguous detection of carbon dioxide clouds. MEX also played a significant role as a data relay satellite for transmissions during the landings of NASA’s Phoenix lander and Curiosity rover. Unprecedented probing of the Martian moon Phobos – which could be a target for future landers and human missions. ESA Science Programme Communication Officer While it is not possible for water to remain stable on the surface today the new result opens the possibility that an entire system of ancient lakes might exist underground, perhaps millions or even billions of years old. https://www.amazon.com/Universe-Today-Ultimate-Viewing-Cosmos/dp/1624145442/, Audio Podcast version:
