This is a step forward on a subkject I have long been urging needs more attention. No one nation can afford to do everything it wants to in space.
Global Exploration Roadmap was developed by the ISECG and is the culmination of work by 12 space agencies, including NASA, over the past year to advance coordinated space exploration.
The roadmap begins with the International Space Station and expands human presence throughout the solar system, leading ultimately to human missions to explore the surface of Mars. The first iteration of the roadmap flows from this strategy and identifies two potential pathways: "Asteroid Next" and "Moon Next." Each pathway represents a mission scenario over a 25-year period, describing a logical sequence of robotic and human missions. Both pathways were deemed practical approaches addressing common high-level exploration goals developed by the participating agencies — serving to inform individual agency decisions related to exploration preparatory activities.
The following space agencies participated in developing the GER (in alphabetical order): ASI (Italy), CNES (France), CSA (Canada), DLR (Germany), ESA (European Space Agency), ISRO (India), JAXA (Japan), (KARI (Republic of Korea), NASA (United States of America), NSAU (Ukraine), Roscosmos (Russia), UKSA (United Kingdom).
