abstract
- Astrobiology, while traditionally focused on understanding the origin of life on Earth and the potential for life elsewhere, offers powerful tools and insights for addressing urgent challenges on our planet. We call for a deliberate integration of astrobiological research with applied science. Knowledge gained from biological systems and study sites on Earth that guide investigation of planetary bodies in our solar system can inform strategies for carbon capture, low-carbon energy production, waste remediation, and biotechnology. Therefore, we argue that astrobiology must evolve to become a bidirectional science that not only explores the cosmos but also supports sustainable life on Earth.
