Small spacecraft big in space research

PASO ROBLES — The Paso Robles City Library invites the public to learn about the CubeSats — a class of research spacecraft called nanosatellites — invented at Cal Poly in the late 1990s that have become an international design standard.

CubeSats can be carried aboard rockets that launch vertically or aboard next-generation vehicles called “spaceplanes” that launch horizontally from airport runways. Once in space, the CubeSats are released into Low Earth Orbit (LEO), where they autonomously position and orient themselves for their mission in the weightless environment using tiny rocket engines about the size of a person’s thumb.


“Having this CubeSat display available in the City Library is a wonderful opportunity for people to come see an example of what modern satellites look like and see how small they actually are, as well as learn more about modern space technology and the key role Cal Poly plays in it,” said Paul Sloan, Economic Development Manager for the City of Paso Robles. 

City Librarian Angelica Fortin adds, “National Library Week is a great time to recognize the variety of ways libraries ignite discovery and learning in our community.”

Originally created for academic research, today most CubeSat launches are for commercial purposes. Some CubeSats have become many countries’ first-ever satellites.

The library is open Monday thru Friday 9 a.m. to 7 p.m. and Saturday 9 a.m. to 4 p.m. Curbside service is available during open hours. Call the library at (805) 237-3870 or visit and the library Facebook and Instagram sites for more information.
