Aurora programme

Lore & Background

The Aurora programme was a response to Europe's Strategy for space, endorsed by the European Union Council of Research and the ESA Council. That strategy had three main points: explore the solar system and the Universe, stimulate new technology, and inspire young Europeans in science and technology. A foundational principle of Aurora was recognizing the interdependence of technology and exploration.

Member states committed to participation for five-year periods, after which they could change their level of participation or pull out entirely. The programme planned flagship missions and arrow missions for key technology demonstrations, such as an Earth re-entry vehicle and a Mars aerocapture demonstrator. Although human spaceflight remained a long-term goal beyond 2030, the thrust was on implementing the ExoMars mission and preparing for an international Mars sample return mission.

The only mission launched under Aurora was the ExoMars Trace Gas Orbiter and Schiaparelli lander, an uncrewed Mars orbiter and lander launched jointly with Russia's Roscosmos in 2016 on a Proton rocket with Fregat upper stage. Other flagship missions considered included the Rosalind Franklin rover (originally part of the Aurora programme's ExoMars mission before cooperation was cancelled in 2022 after the Russian invasion of Ukraine, launch scheduled for 2028 under Terrae Novae), a robotic Mars sample return mission by the mid-2020s, and a human space mission as a long-term goal with no fixed date. No arrow mission was launched.

Reader's Guide

The Aurora programme represents a key phase in European space exploration, bridging early robotic missions toward eventual human spaceflight. Though it never achieved its full roadmap—including human missions to Mars in the 2030s—it laid groundwork through the ExoMars mission, which launched in 2016 and continues under the Terrae Novae programme. The programme's emphasis on technology demonstration, such as Earth re-entry vehicles and Mars aerocapture, informed later efforts. Its cancellation and absorption into Terrae Novae reflects the shifting priorities and international partnerships in space exploration, particularly the end of cooperation with Russia after 2022. Aurora's legacy includes advancing European capabilities in Mars exploration and maintaining a long-term vision for human deep-space missions.

Did You Know?

• The Aurora programme was formally approved by the ESA Council in November 2001 and officially began in 2002.
• Its only launched mission was the ExoMars Trace Gas Orbiter and Schiaparelli lander, launched in 2016 with Russia's Roscosmos; Schiaparelli crashed on Mars and did not operate successfully.
• No Arrow mission was ever launched under the programme.
• The programme's human spaceflight goal was a long-term ambition beyond 2030, with no fixed date for a human Mars mission.
