I was trying to come up with an idea for a fake patent application for April Fool’s day, like a description of something earth-shaking, and completely unbelievable. I planned to provide a detailed description, and then have a link to the “patent application” that was something completely made up.

I come across a lot of unusual patent applications as I’m searching to find what’s been filed by the search engines, like a method of building a better snowman, or creating a crash warning system for cars that learns how to avoid accidents, or even a simple antigravity device, or carrying informational codes in DNA.

I didn’t expect the folks at the Goddard Space Flight Center to come out with a patent application that sounded more like science fiction than science.

The focus of this patent application is on monitoring spacecraft and determining when one craft amongst a fleet may be experiencing problems and can’t continue with a mission. Here’s a snippet from the patent filing:

In one embodiment, each spacecraft could be a worker in an autonomous space mission. The space mission may be configured as an autonomous nanotechnology swarm (ANTS). Each spacecraft in an ANTS may be assigned a specialized mission, much like ants in an ant colony have a specialized mission. Yet, the HNS architecture of each worker in an ANTS may provide coordination and interaction between each HNS that yields performance of the aggregate of the ANTS that exceeds the performance of a group of generalist workers.

More specifically, the SNBFs within HNS 1200 may have a hierarchical interaction among themselves much as the workers do in the entire ANTS collective. Hence, although many activities of the spacecraft could be controlled by individual SNBFs, a ruler SNBF may coordinate all of the SNBFs to assure that spacecraft objectives are met. Additionally, to have redundancy for the s/c mission, inactive workers and rulers may only participate if a member of their type is lost. Besides, a hierarchical worker node can collapse to a non-hierarchical one, if all of the available sub-rulers for that node are lost.

In one particular application of an ANTS, a prospecting asteroid mission (PAM) may survey a large population or surface area targets, such as main-belt asteroids. The primary objective of a PAM could be an exploration of the asteroid belt in search of resources and material with astrobiological relevant origins and signatures. The PAM may include a swarm of approximately 1000 spacecraft that includes approximately 10 types of specialist workers (e.g. HNS 1200) with a common spacecraft bus that is organized into 10 subswarms of approximately 100 spacecraft each, having approximately 10 specialist HNSs.

In some embodiments, each spacecraft in a PAM may weigh 1 kilogram or less with a one-meter diameter body and 100 meters .sup.2 sails when fully deployed. Each spacecraft may be packaged into a 10 cm.sup.2 sided cube. A swarm of 1000 of these spacecraft may fit into 1 meter.sup.3 weighing 1000 kilograms in deployment. Each spacecraft may also include a solar sail propulsion system that requires no expendable supplies and a small nuclear battery that provides sufficient power to each worker. Thus, the prospecting asteroid mission may be self-directed and can be self-sustaining for tens of years.

If you’re interested, the technology in the patent application appears to be available for licensing. NASA wouldn’t be playing an April Fool’s Day prank on us, would they?
