Abstract: Mars represents an important planetary environment for investigating habitability, environmental processes, and potential bio-signatures associated with extraterrestrial life. This theoretical study proposes a conceptual eco-friendly satellite designed to support the investigation of Martian atmospheric conditions, subsurface-water chemistry, and potential biological indicators. The proposed satellite integrates sustainable aerospace design with astrobiological exploration through a range of scientific and observational instruments, including imaging systems, spectrometers, atmospheric sensors, sounders, and navigation cameras.
