This discussion delves into the contrasting approaches of human presence and telepresence in space exploration. We examine the compelling rationales behind human exploration, the overarching goal of potential colonization, and the methods best suited for these objectives. While human exploration is feasible over short terrestrial distances, robotic exploration offers extensive capabilities across the Solar System and beyond. Automated instruments have evolved, becoming more cost-effective and capable, leading the charge in current and future missions. What does the future hold for humans in space?

Human Presence vs. Telepresence • Exactly what are we doing in space? • Compelling rationales are necessary. Is colonization the overarching goal? • What methods serve the objective(s) best? • Human exploration: possible for very short (terrestrial planet distances) distances. • Robotic exploration: possible for Solar System, and possibly beyond. • All serious near-term human spaceflight scenarios seem to end with Mars. • Automated instruments are less expensive and have become increasingly capable. • Robotic surrogates have undertaken the majority of all space exploration missions.
