AeroAstro & emerging tech | contact


Cozy Dark emerging technology began work in 2010 as a skunkworks-style engineering firm and is registered with CCR and NSPIRES.

Our early engineering & design efforts have focused on orbital debris solutions and electrodynamic tether technology.

Zach Urbina founded Cozy Dark with the cooperation of technical, research, and academic colleagues in the Southern California AeroAstro community.

We also have a growing library of space science talks featuring Apollo astronaut Buzz Aldrin, astrophysicist Sean Carroll and more.

Earth Must Have Another Moon, Say Astronomers | A study of the way our planet temporarily captures asteroids suggests that Earth should have at least one extra moon at any one time Back in 2006, the Catalina Sky Survey in Arizona noticed that a mysterious body had begun orbiting the Earth. This object had a spectrum that was remarkably similar to the titanium white paint used on Saturn V rocket stages and, indeed, a number of rocket stages are known to orbit the Sun close to Earth. But this was not an object of ours. Instead, 2006 RH120, as it became known, turned out to be a tiny asteroid just a few metres across—a natural satellite like the Moon. It was captured by Earth’s gravity in September 2006 and orbited us until June 2007 when it wandered off into the Solar System in search of a more interesting neighbour. 2006 RH120 was the first reliably documented example of a temporary moon. But there should be many more examples, say Mikael Granvik and buddies at the University of Hawaii in Honolulu. Today these guys say they have modelled the way the Earth-Moon system captures these objects to understand how frequently we can expect to have additional moons and how long they should stay in orbit. continue reading
