ESA has published new photos of the region on planet Mars called Nili Fossae taken by its Mars Express space probe’s High Resolution Stereo Camera (HRSC). The Nili Fossae are a group of tectonic depressions called graben that show signs not only of geological activity but also of erosion by winds and especially by water that dug the shapes still visible today.

New images captured by ESA’s Mars Express space probe’s High Resolution Stereo Camera (HRSC) show Greeley Crater on Mars. Its name was officially approved in 2015 by the International Astronomical Union (IAU) to honor geologist Ronald Greeley, who passed away in 2011 after having worked on various Mars missions, also being part of the team that manages the HRSC instrument.
A few hours ago the two space probes of ESA and JAXA’s BepiColombo mission blasted off on an Ariane 5 ECA rocket from the Kourou base in French Guiana. Almost 27 minutes after launch, the spacecraft regularly separated from the rocket’s last stage along with the Mercury Transfer Module (MTM), which will provide the propulsion through its ion engines to transport the probes to the planet Mercury.
ESA has published photos taken by its Mars Express space probe of the Cerberus Fossae, fractures that run almost parallel for more than 1,000 kilometers in the area near the equator of the planet Mars. They’re part of a large volcanic complex called Elysium Planitia, where traces suggest that lava flows date back a few million years ago, recent in geological terms compared to the bulk of volcanic activity. The Cerberus Fossae were also formed relatively recently, less than 10 million years ago, probably originated from faults that stretched the upper layers of the surface apart.
A few hours ago the Aeolus satellite was launched on a Vega rocket from the Kourou base in French Guiana. After almost 55 minutes it successfully separated from the rocket’s last stage and entered its Sun-synchronous orbit at an altitude of 320 kilometers (about 200 miles), from where it will study winds globally.
