Launch of second ExoMars postponed to 2022
P
aris-based European Space Agency (ESA) and the Roscosmos Space Corporation have decided to postpone the launch of the second ExoMars mission to study the Red Planet to 2022.
The joint ESA-Roscosmos project team evaluated all the activities needed for an authorisation to launch in order to analyse the risks and schedule.
With due consideration of the recommendations provided by European and Russian Inspectors General, ExoMars experts have concluded that tests necessary to make all components of the spacecraft fit for the Mars adventure need more time to complete.
The primary goal of the mission is to determine if there has ever been life on Mars and to better understand the history of water on the planet.
The ExoMars rover, named Rosalind Franklin, includes a drill to access the sub-surface of Mars as well as a miniature life-search laboratory kept within an ultra-clean zone.
In the frame of a dedicated meeting, ESA and Roscosmos head Jan Worner and Dmitry Rogozin agreed that further tests to the spacecraft with the final hardware and software are needed.
In addition, the parties had to recognise that the final phase of ExoMars activities is compromised by the general aggravation of the epidemiological situation in European countries.
"We have made a difficult but well-weighted decision to postpone the launch to 2022. It is driven primarily by the need to maximise the robustness of all ExoMars systems as well as force majeure circumstances related to exacerbation of the epidemiological situation in Europe which left our experts practically no possibility to proceed with travels to partner industries," said Roscosmos Director General Dmitry Rogozin.
"I am confident that the steps that we and our European colleagues are taking to ensure mission success will be justified and will unquestionably bring solely positive results for the mission implementation," added Rogozin.
"We want to make ourselves 100 pc sure of a successful mission. We cannot allow ourselves any margin of error. More verification activities will ensure a safe trip and the best scientific results on Mars," said ESA Director General Jan Worner.
"I want to thank the teams in the industry that have been working around the clock for nearly a year to complete assembly and environmental testing of the whole spacecraft. We are very much satisfied with the work that has gone into making a unique project a reality and we have a solid body of knowledge to complete the remaining work as quickly as possible," said Worner.
To date, all flight hardware needed for the launch of ExoMars has been integrated into the spacecraft. The Kazachok landing platform is fully equipped with thirteen scientific instruments, and the Rosalind Franklin rover with its nine instruments recently passed final thermal and vacuum tests in France.
The latest ExoMars parachutes dynamic extraction tests have been completed successfully at NASA's Jet Propulsion Laboratory, and the main parachutes are ready for the two final high-altitude drop tests in March in Oregon, US.
The descent module has been undergoing propulsion system qualification in the past month. The ExoMars descent module and landing platform have been undergoing environmental testing in Cannes, France, to confirm the spacecraft is ready to endure the harsh conditions of space on its journey to Mars.
The new schedule foresees a launch between August and October 2022. Celestial mechanics define that only relatively short launch windows (10 days each) every two years exist in which Mars can be reached from Earth.
ExoMars will be the first mission to search for signs of life at depths up to two metres below the martian surface, where biological signatures of life may be uniquely well preserved.
