Welcome to Europe, Kazachok
 

EXOMARS LANDING PLATFORM ARRIVES IN EUROPE WITH A NAME


The platform destined to land on the Red Planet as part of the next ExoMars mission has arrived in Europe for final assembly and testing – and been given a name.

An announcement was made by the Russian State Space Corporation Roscosmos of its new name: ‘Kazachok’.

The ExoMars programme is a joint endeavour between ESA and Roscosmos and comprises two missions. The Trace Gas Orbiter is already circling Mars examining the planet’s atmosphere, while the second mission – comprising a surface science platform and a rover – is foreseen for launch in 2020.

Last month, the rover was named ‘Rosalind Franklin’ after the prominent scientist behind the discovery of the structure of DNA. Now the surface platform also has a name. Kazachock literally means little Cossack, and it is a lively folk dance. 

Once on the martian surface, Rosalind the rover will drive off the Kazachok platform to perform scientific investigations. Kazachok will remain stationary to investigate the climate, atmosphere, radiation and possible presence of subsurface water in the landing site. 

Welcome to Europe

Kazachok left Russia after being carefully packed to meet planetary protection requirements, making sure to not bring terrestrial biological contamination to Mars. It was shipped to Turin, Italy, on an Antonov plane along with ground support equipment and other structural elements.

Packed for Europe

The Italian division of Thales Alenia Space will perform final assembly and testing of the mission in close cooperation with ESA and the Russian Lavochkin Association, the developer and manufacturer of the descent module including the landing platform.

There will be more components arriving to Italy throughout the year, including avionics equipment, the carrier and rover modules and thermal protection systems for the landing platform.

Several test campaigns with ExoMars models are running in parallel in preparation for launch and landing.

Recent shock tests in Russia have successfully proved the mechanical compatibility between the spacecraft and the adapter for the Proton-M rocket that will set ExoMars on its way to Mars.

The ExoMars teams have also just completed the egress and locomotion tests with a full-sized model of the rover in Zurich, Switzerland.

There the rover drove off ramps and through all the terrain conditions that it might encounter on Mars: different types of soil, various obstacle shapes and sizes and all kind of slopes.

“We have now a very challenging schedule of deliveries and tests both in Italy and France. The coordination between the Russian and European teams is key to timely reach the Baikonur cosmodrome in 2020,” says François Spoto, ESA’s ExoMars team leader.

EXOMARS CARRIER MODULE PREPARES FOR FINAL PRE-LAUNCH TESTING

ExoMars carrier module

The module that will carry the ExoMars rover and surface science platform from Earth to Mars has arrived in Italy for final integration preparations.

The module, along with electrical ground support equipment, shipped from OHB System in Bremen, Germany, arrived on 2 April at Thales Alenia Space in Turin, Italy.

The mission is the second in the joint ESA-Roscosmos ExoMars programme that is exploring the possibility of whether life has ever existed on Mars.

The Trace Gas Orbiter is already at Mars, analysing the planet’s atmosphere, and mapping subsurface water. It will also act as a data relay for the next mission, which is scheduled to launch in July 2020, delivering a rover and surface science platform to the Red Planet in March 2021.

The carrier module also provides the communication link between Earth and the spacecraft, and will support navigation with star trackers and Sun sensors. It also carries propellant required for attitude control and manoeuvres through its 16 20-N thrusters that will use up to 136 kg of hydrazine propellant.

To the test

The landing platform, named Kazachok, also recently arrived in Europe from Russia, while the rover, named after Rosalind Franklin, is being fitted out with its scientific instruments at Airbus in Stevenage, UK.

“This is an important milestone, as the carrier module is the ‘vessel’ that will take Rosalind Franklin all the way to Mars,” says Thierry Blancquaert, ESA ExoMars spacecraft systems engineering team leader.

During the nine-month interplanetary journey, the 800-kg carrier module will transport Kazachok and Rosalind the rover within a single, 2-tonne descent module, providing electrical power via a solar array.

The solar panels will generate about 2 kW of power, up to 400W of which can be provided to the descent module; energy is stored in a 24,4-kg battery.

“During the cruise to Mars, the Carrier Module provides all resources to the descent module and rover,” says Stéphane Langlois, ExoMars spacecraft systems engineer at ESA.

“Upon approach to the Red Planet, the carrier module plays a critical role to ensure that the descent module is delivered in the best possible conditions for a successful entry.”

ExoMars separation

Telemetry and data will be stored and transmitted via the onboard computer located in the descent module.

The descent module, which does not produce any power by itself during launch and transfer, will separate from the carrier module shortly before reaching the martian atmosphere. The descent module will deliver the rover and platform safely to the surface while the carrier module will burn up in the atmosphere.

In the coming months, the carrier module will be mated with the descent module.

The resulting composite spacecraft will then undergo further testing to ensure it is ‘qualified’ for its launch into the space environment.

“We are thrilled to see all components finally coming together and we are looking forward to the next phase of testing ahead of launch next year,” says François Spoto, ESA’s ExoMars team leader.
