| Summary/Abstract |
This article analyzes the main motivations behind manned interstellar exploration. There is a wide range of justifications for manned interstellar exploration. Some observers contend that the main reasons are the survival of the human species and the spreading of life in the universe. I argue that the survival of the human species is a very long-term threat and, as such, it is not the main driver for interstellar exploration within a reasonable time horizon. The discovery of habitable planets within 5 to 15 light years from Earth and the possibility that Earth will no longer define the limit of growth constitute stronger motivations. I argue that manned interstellar exploration will be achieved through the mobilization of both public and private resources, as in the past opening of new frontiers, with governments providing initial support in exploration and science, in advancing critical technologies, and in building space infrastructure. The private sector would then take the lead in creating new markets and in expanding humanity's presence in space.

| Summary/Abstract |
The development of off-world sources of critical minerals is creating an opportunity to transform space activity from a consumer of resources into sources of value. This article provides an overview of the rationale for and the feasibility of asteroid mining, based on current technology and information. It concludes that the mining of asteroids is a medium-term to long-term project (20 to 30 years) that requires a stepwise approach. An important step in the development of asteroid mining is the confirmation, through exploration, of the minerals’ abundance on the asteroids. A mission capturing and returning to lunar orbit a single 10-meter-diameter asteroid or a rock off the surface of a larger asteroid accomplishes this goal. This mission would also allow the testing of automated mining and processing equipment, reducing the risks of future large-scale asteroid mining operations. Suggested herein is that asteroids’ exploration be carried out through a partnership between space agencies and private space companies, whereby the two partners can achieve their strategic interests.
