A long-awaited moment in the ExoMars mission will be when ESA’s Rosalind Franklin rover leaves the landing platform, Kazachok, and drives onto the martian soil for the first time. The egress is a carefully choreographed move that engineers are rehearsing on Earth.

Rosalind’s twin on Earth, known as Amalia, has successfully left the platform in a Mars terrain simulator at the ALTEC premises in Turin. The test model borrows its name from renowned astrophysicist Professor Amalia Ercoli Finzi. Amalia was  the first woman to graduate in aeronautical engineering in Italy, and she strongly pushed for the development of the ExoMars drill already 20 years ago.

While the driving during these exercises takes about 15 minutes, the whole egress is a long and crucial operation that will last a few martian days. After landing, the rover will be busy for over a week unfolding its wheels and deploying the mast, among other checkouts.  

The landing platform has two exit ramps: one at the front and another one at the back. Rosalind is designed to negotiate steep inclines on the ramps, but it is up to ground control on Earth to decide which is the safest way to drive off.

Engineers are using the Amalia rover to recreate different scenarios and help them take decisions that will keep Rosalind safe in the challenging environment of Mars. The model is fully representative of what the rover will be able to do on the Red Planet.

Amalia has so far demonstrated drilling soil samples down to 1.7 metres and operate all the instruments while sending scientific data to the Rover Operations Control Centre (ROCC), the operational hub that will orchestrate the roaming of the European-built rover on Mars.
