With not too much fanfare, December saw the Mars Express mission operations team at ESOC bringing the VMC back online, again. You'll recall that VMC went offline in late 2011 when Mars Express suffered problems with the mass memory storage. The spacecraft and instruments were fully back in routine operation by January 2012, meaning that the team could then devote some 'time-available' time to recommissioning VMC. In addition to getting the camera itself running (marked by the first symbolic data transmission of a VMC image via Malargüe station), we also set up a new blog channel and a dedicated Flickr page to host the images (and the Twitter account – @esamarswebcam – is still running).

Following the first downlink over Malargüe tonight, we will consider the Flickr page to be open for business. Unfortunately, due to the upcoming solar conjunction and associated low bit-rate season, we're unlikely to get any downlink slots for VMC for a few months, but once the Mars Webcam is taking pictures again, the images will be published for the world to see within seconds of them being received on Earth. The low priority of VMC images means that their downlink to Earth can be some time after the observation.
An image of the enigmatic Red Planet acquired by ESA’s Mars Express on 15 December 2012 was downloaded via ESA’s new tracking station in Malargüe, Argentina, symbolising ‘first data’ and recognising formal inauguration.

On 18 December 2012, the station downloaded a VMC image from Mars Express orbiting some 328 million kilometres from Earth to mark the station's formal inauguration and the symbolic transmission of 'first data'. The image was received at ESA's European Space Operations Centre, Darmstadt, Germany, and processed by the Mars Express mission operations team.

This is the first image of Mars to be acquired by the VMC camera on board Mars Express since the spacecraft was recovered from a major system fault in autumn 2011. This test image was acquired on 6 May 2012 at 00:45:28 UT. The VMC is now being recommissioned and tested, and is expected to be back in routine service by mid-2012.
