In-Space Manufacturing with CubeSats

Two new in-space manufacturing research missions were recently deployed into low Earth orbit. The missions, MakerSat-1 and Orbital Factory 2, are each housed in 1U CubeSats (10x10x10cm). MakerSat-1 is studying the degradation of common 3D printer plastics in space, and Orbital Factory 2 is demonstrating 3D printing of conductive material, simulating a solder joint repair on a solar array while in microgravity.

Deorbit Tethers Promise Great Utility to Minimize Space Debris

A new deorbit tether will be tested by Aurora Propulsion Technologies in December 2020. The 1.5U CubeSat test will ride to space on a SpaceX Falcon 9 rocket, after which it will be propelled to a sun-synchronous orbit via Momentus Space Vigoride. In addition to the tether, Aurora will test and utilize their new water thrusters for cubesat control.

ESA Lunar Ice Drill and Lab

Planned to land on the Moon in 2025, the Roscosmos Luna 27 will carry an ESA designed robotic drill and laboratory dedicated to collecting and processing volatiles from regolith. While we know ice exists within permanently shadowed regions (PSRs) at the lunar poles, little is known about the exact composition and structure. In-situ sampling is therefore essential for understanding this ice, allowing engineers to build better ice processing systems.

In-Space Robotic Assembly by Maxar Technologies

NASA’s upcoming Restore-L mission will seek to service a low-Earth orbit satellite, bringing it closer to its original state. The spacecraft is planned to launch in 2023, where it will demonstrate autonomous rendezvous, refueling, repairing, and manufacturing tasks. NASA has used public-private partnerships to procure technology payloads for this mission in order to promote industry innovation at low cost.

Studying a NEA with the M-ARGO CubeSat

ESA and their partners are pushing CubeSats further than they’ve ever been before. The M-ARGO (Miniaturised Asteroid Remote Geophysical Observer) mission is a 12U CubeSat that will be launched on a rideshare mission before using it’s own propulsion to visit a sub-100 meter wide asteroid. This mission will demonstrate a cost effective way to explore near-Earth asteroids (NEAs).

The Space Resource Report: 2020

China dominates. Asteroid mining dies but attends its own funeral. Reusable rockets lower the cost and increase access to space. The Moon, Mars, and asteroids all get new survey maps for water resources. Water-based thrusters perform well in orbit. Asteroids are blasted and samples collected. Space mining gets more legal scaffolding. The Moon gets one new rover and two new craters.
