ESA Resumes ExoMars Mission: A Detailed Overview
Background of ExoMars Mission:
The ExoMars mission is a collaborative effort between ESA and Roscosmos, the Russian space agency. Its primary goal is to search for evidence of life on Mars, particularly focusing on past microbial life. To achieve this, the mission involves sending a rover, named Rosalind Franklin, to the Martian surface equipped with advanced scientific instruments.
The Setback:
Originally scheduled for a launch in September 2022, the ExoMars mission encountered obstacles following Russia's invasion of Ukraine in February 2022. As a result, ESA suspended its cooperation with Roscosmos on the mission, leading to uncertainties and delays in the project.
The Recent Development:
In a significant move to revive the ExoMars mission, ESA announced on April 9 that it had awarded a contract worth 522 million euros ($567 million) to a consortium led by Thales Alenia Space. This contract aims to restart work on the mission and ensure its continuation despite the previous challenges.
Key Components of the Contract:
The contract entails several critical aspects to move the ExoMars mission forward:
1. Replacement of Russian Contributions: One of the primary tasks under the contract is to replace some of the contributions that Russia was providing to the mission. This includes designing a new landing platform to replace the original Russian design.
2. Involvement of Consortium Members: Thales Alenia Space, serving as the prime contractor, will lead the design of the new landing platform. Airbus Defence and Space, responsible for building the rover, will provide mechanical, thermal, and propulsion systems for the landing platform. Other consortium members include ArianeGroup and OHB, which will contribute to the project with their expertise in specific areas.
3. Development of Entry, Descent, and Landing (EDL) Technologies: A significant focus of the contract is on developing new capabilities in entry, descent, and landing (EDL) technologies. This involves ensuring the safe landing of the rover on the Martian surface, a crucial aspect of the mission's success.
4. Integration of NASA Contributions: In addition to European efforts, the ExoMars mission will incorporate contributions from NASA. These include providing aerobraking engines and radioisotope heating units (RHUs) to keep the spacecraft warm during its journey to Mars.
Future Plans and Launch Schedule:
With the new contract in place, ESA aims to get the ExoMars mission back on track and proceed with its planned objectives. The mission is now scheduled for a launch in the fourth quarter of 2028, with NASA providing the launch vehicle. Although the specific rocket for the launch has not been selected yet, NASA is actively procuring one for the mission.
Challenges and Outlook:
While the contract marks a significant step towards resuming the ExoMars mission, challenges still lie ahead. The complexity of refurbishing and adapting various components for the mission poses ongoing challenges. However, ESA views the contract as a major stabilization of the program, signaling a return to a typical space program trajectory.
Conclusion:
The decision to award the contract for the ExoMars mission represents a significant milestone in ESA's efforts to explore Mars and search for signs of life beyond Earth. Despite past setbacks, the agency remains committed to advancing scientific exploration and unlocking the mysteries of the Red Planet. With renewed momentum and international collaboration, the ExoMars mission is poised to make groundbreaking discoveries in the quest for extraterrestrial life.
