Chang Díaz was honored with the Liberty Medal in 1986 by President Ronald Reagan and was a four-time recipient of NASA’s Distinguished Service Medal, the highest honor awarded by the agency. He currently is leading Costa Rica’s "Strategy for the XXI Century,” a countrywide initiative aimed at transforming Costa Rica into a fully developed nation over the next 40 years.
