The Visual Monitoring Camera (VMC), also known as the Video Monitoring Camera and Mars Webcam, is a small camera mounted on "Mars Express" spacecraft. It is operated by the Mars Express Flight Control Team at ESOC in Darmstadt, Germany. Originally, VMC was a technical camera to monitor the separation of the Beagle 2 lander, but after a few years, it was repurposed into Mars Webcam, streaming its data to the web and even being used for science.
