 Long Lived In-situ Solar System Explorer

The Long Lived In-situ Solar System Explorer (LLISSE) is a proposed spacecraft mission concept aimed at exploring the solar system, particularly focusing on planets and celestial bodies like Mars, Venus, and other locations within the inner solar system. The primary goal of LLISSE is to conduct long-duration, in-situ scientific investigations, which would involve long-term studies of the environments and conditions on these celestial bodies.
