Ricardo Peralta y Fabi (15 August 1950 â 16 October 2016) was a Mexican mechanical engineer and former astronaut trainee who was a backup for astronaut Rodolfo Neri Vela on STS-61-B. Peralta was one of three people selected among 400 applicants to the Mexican space program.
Peralta was the alternate of the first Mexican astronaut Rodolfo Neri Vela at the time of the ultralight accident (bought as remuneration for astronaut training), in which he was seriously injured. He was unable to complete astronaut training and training at Indiana University. He left the corps of astronauts on 3 December 1985.
He taught at the National Autonomous University of Mexico (UNAM) for many years after his astronaut career and died in 2016.
