Cislunar Economy: Tugs, Depots, and Lunar ISRU
The cislunar economy refers to commercial and logistical activities occurring between Earth and the Moon. "Tugs" are spacecraft designed to transport cargo and vehicles across cislunar space. "Depots" serve as storage and refueling stations for propellant and supplies, enabling longer missions. "Lunar ISRU" (In-Situ Resource Utilization) involves extracting and using lunar resources, such as water and minerals, to support operations and reduce reliance on Earth-based supplies, making sustained lunar activities feasible.

💡 Key Takeaways
- Define the cislunar economy and name its core components: tugs, depots, and lunar ISRU.
- Explain how cislunar tugs move cargo and vehicles between Earth and the Moon, enabling logistics in space.
- Describe the role of depots as storage and refueling hubs that extend range and mission duration in cislunar operations.
- Understand lunar In-Situ Resource Utilization (ISRU) and how extracting Moon resources can support propellant, life support, and construction needs for sustained missions.
❓ Frequently Asked Questions
What is the cislunar economy?
The network of commercial and logistical activities between Earth and the Moon, including transportation, storage, refueling, and resource utilization.
What are tugs in cislunar space?
Tugs are spacecraft designed to move cargo and vehicles across cislunar space, connecting Earth orbit, depots, and the lunar vicinity.
What are depots and why are they important?
Depots are storage and refueling stations that hold propellant and supplies, enabling longer, more flexible missions by reducing the need for constant Earth resupply.
What is Lunar ISRU?
Lunar ISRU (in-situ resource utilization) means extracting usable materials from the Moon, such as water ice or oxygen, to support fuel, life support, and construction on-site.
How do tugs, depots, and ISRU enable a sustainable cislunar economy?
Together, they lower mission costs, reduce reliance on Earth resupply, enable longer and more frequent missions, and create a scalable transport and support network for exploration and commercial activity.
