European Mars missions on track

ESA's mission to Mars in 2016 has entered the final stage of construction with the signing of a contract with aerospace company Thales Alenia Space.

ExoMars will fly two missions, in 2016 and 2018, in a partnership between ESA and the Russian space agency, Roscosmos. Its main goal is to answer one of the outstanding scientific questions of our time: has life ever existed on Mars?

In addition, ExoMars will develop new European technical capabilities in landing, roving, drilling and preparing samples to pave the way for a future Mars sample-return mission in the 2020s.

The first mission will be launched in 2016 and will include the Trace Gas Orbiter (TGO) to search for evidence of methane and other atmospheric gases that could be signs of active biological or geological processes.

It will also deliver the Entry, Descent and Landing Demonstrator Module (EDM) to the surface of Mars, to demonstrate key technologies needed for the 2018 mission and future landing missions.

The 2018 mission will land a rover on Mars – the first with the capability of drilling to depths of 2m to collect samples that have been shielded from the harsh conditions on the surface, where radiation and oxidants can destroy organic materials.

In addition, the 2018 mission carries a Surface Platform with scientific instruments to investigate the martian environment.

The agreement, signed in the ESA pavilion at the Paris Air & Space Show, marks a major milestone for the mission and for Thales Alenia Space, the industrial prime contractor on ExoMars.

"The award of this contract provides continuity to the work of the industrial team members of Thales Alenia Space on this complex mission, and will ensure that it remains on track for launch in January 2016," noted Alvaro Giménez, ESA's Director of Science and Robotic Exploration.

For the 2016 mission, Thales Alenia Space Italy is building the EDM, which is currently completing structural tests at the company's laboratories in Turin. TGO's orbiter is being built at Thales Alenia Space's site in Cannes, France.

The first mission will be launched in January 2016, arriving at Mars nine months later. The second mission is scheduled for launch in May 2018, arriving at the planet in early 2019.
