The thirteenth paper of the LIFE series (Alei et al. 2024, https://arxiv.org/abs/2406.13037) has recently been accepted on Astronomy and Astrophysics. In this paper, we explore the potential of two upcoming space missions, the Habitable Worlds Observatory (HWO) and the Large Interferometer for Exoplanets (LIFE), in characterizing Earth-like exoplanets. W asesess how these missions, which focus on different spectral ranges (UV/VIS/NIR for HWO and MIR for LIFE), can independently and synergistically enhance our understanding of planetary atmospheres. Our findings suggest that combining data from both missions could significantly improve our ability to detect biosignatures and characterize potentially habitable exoplanets, marking a pivotal advancement in the search for life beyond our solar system.
