Abstract
In 1995 during the Zeolite Meeting' 95 in Sofia, Bulgaria, Ivanova et al., entitled their paper on the use of natural zeolites in space applications as “Zeolite Gardens in Space”. This Chapter presents the subject of natural zeolites in space applications and occurrence in extraterrestrial environments. The Chapter is dedicated to Frederick A. Mumpton and Robert S. Bowman whom I had the luck and the honor to meet in Thessaloniki, Greece in 2002 during the 6th International Conference on the Occurrence, Properties and Utilization of Natural Zeolites. I hope the gardens in space to be wide open to them.
Keywords: Natural zeolites, space applications, extraterrestrial environment, Mars, life support systems, hydroponics.
