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.
