Scientists have selected Oxia Planum, a shallow basin connected to dried up channels carved by ancient water flows, as the prime landing site for Europe’s first Mars rover set for launch in 2018.

Arianespace chief executive Stephane Israel announced an anomaly occurred during Thursday’s flight of an Ariane 5 rocket from Kourou, French Guiana, shortly after the launcher’s second stage engine ignited.
