Crossing Phobos 2.0

We received an update from Robert Guilanya, flight dynamics lead for ExoMars/TGO, earlier today.

Four decades of Vilspa

On 1 September 2017, ESA’s VIL-2 antenna and its supporting facilities was formally retired after 36 years’ service.

Crossing Phobos

We did our best to ensure that Phobos would be at the farthest possible point away from TGO when we cross the moon's orbit.

VMC went pro and goes great

The VMC camera on Mars Express is delivering some of the best images ever, showing the Martian surface in excellent detail, colour and contrast.
