The European Space Agency (ESA) has officially adopted ARRAKIHS as a scientific mission, setting a target launch date of 2030. The initiative aims to investigate the low surface brightness universe, focusing on dark matter and other faint cosmic structures that have eluded detailed observation.
ARRAKIHS is expected to provide unprecedented insights into the dark components of the cosmos, which make up most of the universe's mass but remain poorly understood. The mission's focus on low surface brightness phenomena could help answer fundamental questions about galaxy formation and evolution.
Matthieu Schaller, a member of the science team, expressed enthusiasm about the project. "I look forward to learning more about the dark part of our cosmos," he said. The mission's adoption marks a significant milestone in ESA's long-term science program.
With launch still four years away, the agency will now proceed with detailed design and construction phases. The mission's success could redefine our understanding of dark matter and its role in shaping the universe we observe today.
Some astronomers caution that observing low surface brightness features is technically challenging, and the mission's instruments must achieve extremely high sensitivity to avoid background noise.
