ESA embarks on 'galactic archaeology mission' with Austria

The European Space Agency (ESA) has given the green light to a new space mission, Arrakihs, which is being described as a "galactic archaeology mission." This designation highlights the probe's objective: to delve into the mysteries of dark matter and unravel the historical evolution of galaxies.

Arrakihs is part of ESA's "Cosmic Vision" program and has been classified as a FAST-class (Fleet of Agile Small Telescopes) mission. This classification signifies a streamlined development process, allowing the project to move from its selection in 2022 to its launch in under a decade. The mission's formal acceptance by the ESA's science program committee marks a significant step forward.

The probe's scientific goals are ambitious. It aims to analyze the faint structures surrounding galaxies, often referred to as halos, which are thought to contain significant amounts of dark matter. By studying these remnants, scientists hope to gain a deeper understanding of how galaxies formed and evolved over cosmic time.

Austria is noted as a partner in this endeavor, indicating international collaboration in advancing space science. The mission's rapid timeline underscores ESA's commitment to accelerating scientific discovery and exploring the universe's fundamental components, such as dark matter and galactic history.
