BREAKING: A robot developed by Caltech and funded by DARPA has successfully built part of a structure in orbit without astronauts, marking what researchers describe as the first autonomous construction of a structure in space.
The experiment, called ASTRA, uses a robotic arm to retrieve individual structural tubes and connecting joints, then assemble them into sections of a larger framework directly in orbit.
Launched aboard a SpaceX Falcon 9 in March, the system has spent approximately six months in space testing the technology.
The robot successfully constructed a new section of a truss structure, demonstrating that spacecraft could eventually assemble large structures from smaller components rather than launching them fully assembled.
The experiment is part of DARPA's NOM4D program, which aims to enable construction of enormous structures in orbit, potentially hundreds of meters or even kilometers across.
Potential applications include:
> Giant space telescopes
> Large satellite communications antennas
> Orbital solar power stations
>Future space infrastructure too large to fit inside conventional rockets
The demonstration did not complete the full planned antenna, but establishes an important proof of concept for autonomous orbital construction.
The technology could eventually allow the size of structures built in space to exceed the physical limits of the rockets used to launch their components.

Putting enforcement outside the agent’s reach is a serious step.
Here’s the test I’d want to run:
Agent A delegates to B. B delegates to C.
You revoke A’s authority.
Can C still spend money or execute a queued action?
Every handoff needs a verifiable chain of authority. Every action needs a check that the permission still holds.
That’s a problem we’re working on at Only Then Labs.
Revocation has to travel as far as delegation.
We’ve launched NVIDIA Open Agent Safety Platform to help people control what AI agents can access and do.
Agents can write code, use tools, and work on complex tasks for hours or days. That work requires access to data and systems, along with clear limits on how they’re used.
NVIDIA OpenShell enforces permissions around the agent’s work. BlueField-4 and DOCA add independent monitoring and security controls in the infrastructure, outside the agent’s reach. Vera CPUs power the work itself.
Together, these technologies give teams a foundation for putting agents to work with defined permissions, oversight, and protection.

AGI has arrived. Now comes the inheritance problem.
What state is allowed to become truth?
Who had authority to change it?
What survives the handoff?
What is the next intelligence actually permitted to trust and act on?
A signature proves who signed. Provenance proves what happened. Neither proves the transition was legitimate.
We’ve been building the admission, authority, continuity, revocation and witness layer for exactly this.
400K GPUs can scale intelligence. They cannot scale legitimate authority.
