NASA Posts Global Exploration Roadmap
The GER begins with the International Space Station and expands human presence throughout the solar system, leading ultimately to crewed missions to explore the surface of Mars.
The roadmap identifies two potential pathways: "Asteroid Next" and "Moon Next." Each pathway represents a mission scenario that covers a 25-year period with a logical sequence of robotic and human missions. Both pathways were deemed practical approaches to address common high-level exploration goals developed by the participating agencies, recognizing that individual preferences among them may vary.
