Refueling in orbit is redefining the economics and possibilities of space. What Are Orbital Tugs?Orbital tugs are autonomous spacecraft that maneuver, service, or transport other space assets. Increasingly, one of their most valuable roles is refueling satellites and spacecraft mid-mission—directly in space. This isn’t science fiction. It’s operational reality. By enabling spacecraft to replenish fuel […]
A new class of orbital infrastructure is transforming how we operate in space. What Is a Space Tugboat?Space tugboats are autonomous spacecraft designed to maneuver other objects in orbit. Just as maritime tugboats move larger vessels through ports, space tugs reposition satellites, deliver cargo, and perform in-space servicing like refueling and repairs. These vehicles don’t
Resource extraction in space doesn’t begin with a shovel—it begins with a fuel plan. Mining Requires a Logistics Backbone No infrastructure, no industry Space mining—on the Moon or from asteroids—isn’t just about finding resources. It’s about moving them. And none of that is possible without fuel logistics: a system of cryogenic storage, refueling depots, and
The Moon may not just power missions—it may power markets. From Destination to Distribution Hub The Moon’s role is evolving—from target to enabler Most current plans treat the Moon as a place to explore or mine. But a more strategic view sees it as a logistics node—a platform for fueling outbound missions across the solar
If you can’t move the material, the mine doesn’t matter. Mining Requires Movement, Not Just Extraction Digging is step one—delivery is what matters Mining is never just about removing material from the ground. It’s about moving it—efficiently, safely, and profitably. This is especially true off-Earth, where lunar and asteroid mining efforts face an unforgiving truth:
Mining the Moon or asteroids starts with a single question: how much energy does it take to get there—and back? What Is Delta-V? Think of it as the currency of movement in space Delta-v (Δv) stands for “change in velocity.” In spaceflight, it’s the amount of speed change a spacecraft needs to reach a target,
