Book excerpt: Future perspectives on space-borne/ground-based state-of-the-art scientific instruments, exploration space missions, and advanced modeling/simulation methods, are intensively discussed from multilateral viewpoints regarding solar-terrestrial physics, space plasma, upper atmospheric observations for the Earth and planets. In addition to innovative technologies, international collaborations have been getting more essential and crucial factors in the space observations/missions. The novel concept, strategy, and promotion in these international collaborations are also main subjects of this conference.
