The Space Internet: Space Bacon-DARPA

DARPA’s  Space-Based Adaptive Communications Node (Space-BACN) would allow seamless communication between various constellations of satellites that currently cannot talk to each other.

“There could be tens of thousands of small satellites launched into Low Earth Orbit over the next decade as the demand around the world for affordable space-based capabilities grows,” said Greg Kuperman, Space-BACN program manager in DARPA’s Strategic Technology Office. “The problem with this growth is that optical communications links are currently engineered to only connect satellites within a given constellation – they can’t dynamically adapt waveforms to communicate with satellites in other constellations. This lack of standardization results in a fragmented, stove-piped ‘Wild West’ space domain with new satellite constellations that can’t interoperate, government satellites that can’t communicate between one another, and government satellites unable to take advantage of emerging commercial communications capabilities.”

Space-BACN envisions an adaptable communications terminal that could be reconfigured on-orbit to talk across different standards, presenting a leap in technology from the current state of the art. Space-BACN will involve inter alia a novel cross-constellation command and control approach to automate interactions between government and commercial satellites

Space-BACN has significant military and civilian uses.

Building Factories in Space: DARPA

DARPA announced on February 5, 2021  its Novel Orbital and Moon Manufacturing, Materials and Mass-efficient Design (NOM4D) program. The effort, pronounced “NOMAD,” seeks to pioneer technologies for adaptive, off-earth manufacturing to produce large space and lunar structures,  “NOM4D’s vision is to develop foundational materials, processes, and designs needed to realize in-space manufacturing of large, precise, and resilient Defense Department systems,” said Bill Carter, program manager in DARPA’s Defense Sciences Office. “We will also explore the unique features of in-situ resources obtained from the moon’s surface as they apply to future defense missions.” 

Concerning mass-efficient designs, the vision is for completely new concepts that could only be manufactured in space….In order to take the next step, we’ve got to go about materials, manufacturing, and design in a completely new way.
