Synopsis
Here is a summary of the key points from the paper:
Overview
- The paper discusses the emerging in-space economy, including activities like space mining, manufacturing, tourism, and infrastructure. It was presented at the International Astronautical Congress in 2023.
In-Space Mining
- Asteroids and the Moon contain valuable resources like water, precious metals, and rare earth elements that could be mined and used for in-space manufacturing and life support.
- Companies like Planetary Resources and Deep Space Industries are developing technologies for prospecting and mining asteroids.
In-Space Manufacturing
- Manufacturing products in space from extracted resources could enable self-sustaining human presence and decrease costs of space activities.
- Products like spacecraft components, fuels, metals, and plastics could be manufactured.
- In-space manufacturing could also enable mega-structures like solar power satellites and space settlements.
Space Tourism
- Suborbital and orbital space tourism is a growing industry with companies like Blue Origin, Virgin Galactic, and SpaceX.
- In the future, space hotels, private space stations, and trips around the Moon could become available.
Space Infrastructure
- An in-space transportation infrastructure needs to be developed including refueling depots, space tugs, and orbital transfer vehicles.
- On-orbit satellite servicing is also an emerging capability for inspection, repair, upgrade, and assembly of satellites.
Challenges
- Technical challenges for in-space resource utilization and manufacturing need to be solved.
- A supportive legal/policy framework needs to be developed by international treaties.
- Sustainability guidelines are needed to ensure responsible use of space resources.
