The primary simulation of the ExoMars rover driving off its touchdown platform closed out an unbelievable 12 months of preparations because the mission now marches with confidence in the direction of a September launch.
ESA’s Rosalind Franklin rover begins the 12 months with months of profitable upkeep and useful exams behind it. All its devices are go for flight, with some minor tuning left to finish this month.
“The rover is prepared, and along with the current drop check success for the parachutes, we're optimistic to be in time for the September launch date,” says Pietro Baglioni, ESA’s ExoMars rover staff chief.

Solely as soon as each two years and for about ten days, celestial mechanics would enable the spacecraft to achieve Mars from Earth within the shortest attainable time – round 9 months.
Rosalind now sits in an ultra-clean room on the Thales Alenia Area premises in Turin, Italy, proper by its touring companion, the Kazachok touchdown platform. Following a last overview on the finish of March, all of the elements of the spacecraft – rover, descent module, touchdown platform, and provider – will transfer to the launch website in Baikonur, Kazakhstan, to organize for lift-off.
“Simply earlier than that final journey on Earth, we are going to add the ultimate model of the software program that may enable the rover to scout Mars autonomously,” explains Pietro.
First martian strikes
Following the nerve-wracking descent to the floor of Mars, a long-awaited second within the ExoMars mission will likely be when Rosalind leaves the touchdown platform and drives onto the martian soil for the primary time. The egress from Kazachok is a fastidiously choreographed transfer that engineers are rehearsing on Earth.
The dual of ESA’s Rosalind Franklin rover has efficiently left the platform throughout current exams in a Mars terrain simulator on the ALTEC premises in Turin.
Whereas the driving throughout these workout routines takes about quarter-hour, the entire course of will final a couple of martian days. After touchdown, the rover will likely be busy for over every week unfolding its wheels and deploying the mast, amongst different checkouts.
“The egress is an extended and essential operation. We should be light and run it in a really gradual movement for additional security,” explains Andrea Merlo, ExoMars head of robotics from Thales Alenia Area.

The touchdown platform has two exit ramps: one on the entrance and one other one on the again. Rosalind is designed to barter steep inclines on the ramps, however it's as much as floor management on Earth to determine which is the most secure strategy to drive off.
“As soon as the six wheels hit the martian floor, will probably be the start of the story for this rover on Mars. We really feel prepared and are actually wanting ahead to the actual mission,” says Andrea.
Amalia and Rosalind
The ExoMars twin rover, till now dryly often called the Floor Take a look at Mannequin, has a brand new identify: Amalia. This check mannequin borrows its identify from Professor Amalia Ercoli Finzi, a famend astrophysicist with broad expertise in spaceflight dynamics.

Amalia was the primary lady to graduate in aeronautical engineering in Italy, and apart from serving as a scientific advisor for ESA and NASA, she designed the drill on Rosetta’s lander Philae and strongly pushed for the event of the ExoMars drill already 20 years in the past.
“I'm flattered and honored to have this important ingredient of the ExoMars mission named after me. Mars is ready for us,” stated Amalia after receiving the information.
Engineers are utilizing the Amalia rover to recreate totally different situations and assist them take selections that may maintain Rosalind protected within the difficult surroundings of Mars. The mannequin is absolutely consultant of what the rover will have the ability to do on the Purple Planet.
“The enjoyable has began. We are going to use Amalia to run dangerous operations, from driving round martian slopes in search of the very best path for science operations to drilling and analyzing rocks,” explains Andrea.
The reproduction ExoMars rover – the Floor Take a look at Mannequin (GTM), also referred to as Amalia – that will likely be used within the Rover Operations Management Centre to assist mission coaching and operations has accomplished its first drive across the Mars Terrain Simulator.

Amalia has to date demonstrated drilling soil samples right down to 1.7 meters and working all of the devices whereas sending scientific knowledge to the Rover Operations Management Centre (ROCC), the operational hub that may orchestrate the roaming of the European-built rover on Mars.
It takes a staff
The trouble to reach on the beginning line in time has been extraordinary, with double shifts and no time for breaks in 2021 amidst COVID -19 pandemic disruptions.
“The cooperation between European and Russian business, the coordination between house companies and the work of the technical groups have been outstanding,” praises Pietro.

Groups have solved essential points working in parallel, such because the parachute system and the descent module electronics, with sufficient margin for a launch in September 2022. Preparations for launch have began in Baikonur, and a devoted assist staff is in place at ESOC heart in Darmstadt, Germany.
The ESA-Roscosmos Hint Gasoline Orbiter is ready for the arrival of ExoMars to the Purple Planet. Along with its personal science mission, the orbiter relays knowledge from NASA’s Perseverance rover. Additionally on the martian floor since 2021 is China’s Zhurong rover.
“It’s not lengthy to go earlier than the European rover can lastly be part of the opposite martian drivers in 2023 with a prime class scientific laboratory on board,” says Pietro.

The ESA-Roscosmos ExoMars 2022 mission will launch on a Proton-M rocket with a Breeze-M higher stage from Baikonur, Kazakhstan, within the 20 September – 1 October 2022 launch window. A provider module will transport the descent module with the Rosalind Franklin rover and Kazachok floor science platform inside, to Mars. As soon as landed safely within the Oxia Planum area of Mars on 10 June 2023, the rover will drive off the floor platform, in search of out geologically attention-grabbing websites to drill beneath the floor, to find out if life ever existed on our neighbor planet. The ExoMars program additionally contains the Hint Gasoline Orbiter, which has been orbiting Mars since 2016. In addition to its personal science mission, Hint Gasoline Orbiter will present important knowledge relay providers for the floor mission.
In Europe, the rover is a three way partnership between Thales Alenia Area and Leonardo. Thales is the commercial prime, Leonardo offering the drill, OHB the advanced laboratory mechanisms and 9 totally different instrument groups from ESA Member States, NASA/JPL and IKI/Roscosmos offering the payload. Airbus UK is accountable for the rover automobile.
