On June 30, 2015, Richard joined a panel discussion on the Milt Rosenberg Show to talk about the history and future of space exploration.
Other guests were Bill Melberg, a former aviation executive and now editor of AmericasUncommonsense.com, professional speaker and frequent writer on aerospace topics, and Dr. Paul Spudis, an astrogeologist and moon expert who is senior staff scientist at the Lunar and Planetary Institute in Houston, Texas.

Milt Rosenberg welcomes Bill Melberg and Richard Easton to the WCGO studio. On the desk in front of them sits a prototype model of the camera used on Surveyor I, the first unmanned lunar soft-lander.
On March 1, Richard Easton and Eric Frazier joined Dr. David Livingston, host of The Space Show, for a discussion about GPS modernization. Topics included new capabilities, schedule delays, cost overruns, international competition and potential threats to the system–a concern shared by many listeners, as evidenced by questions posed by email and callers.

Keely Grasser, author of “From Duct Tape to Drones: Military Inventions That Impact our World,” in the Winter 2015 edition of Phoenix Patriot Magazine, interviewed Richard Easton and Eric Frazier for background information on GPS, one of eight innovations covered in the article. The key point she makes: GPS technology has spread throughout so many military, commercial and consumer industries that economists now find it impossible to accurately put a dollar figure on its overall worldwide impact.
Business Insider recently spoke with Richard Easton for input on its article, How Does GPS Work?
Richard noted that while GPS costs about $1 billion a year to maintain and replenish, it produces perhaps $100 billion per year in economic benefits, quite a “bang for our buck.”
Applications for GPS continue to expand, owing largely to a decision made at the beginning–to make the system passive. GPS satellites broadcast one-way signals, like a radio station, meaning an unlimited number of users can share them without transmitting anything back to the satellite, which would saturate the system and limit its use.

Public Lecture Series feat. Richard Easton – May 5, 2014 from The Explorers Club on Vimeo.
From Harrison to GPS – This lecture traces the development of navigation from the 18th century longitude problem to the invention of the Global Positioning System. Easton will describe the two major proposed solutions to the longitude problem: accurate clocks as developed by John Harrison and observations of celestial objects such as lunars and the Jovian moons. He will then trace the history of satellite navigation proposals culminating in GPS which combines the two 18th century proposals, putting accurate synchronized clocks in satellites which are artificial celestial objects.
