The Centennial Experimental Farm's Biodome*

In 1966 NASA, the Canadian National Science Research Establishment, and the Centennial Experimental Farm agreed to build a biodome test facility on the farm's grounds to simulate growing exotic tropical plants on the Moon. It was believed that if these plants could thrive throughout an Ottawa winter, the Moon would pose no difficulties. If successful, lunar construction of such a facility was slated to begin with NASA's Apollo 30 mission. 

Funding ran out in 1970, and the project was scrubbed from Apollo 30's manifest. However, the facility was revived in 1977 in anticipation of the creation of the ExoBioLab facility for the then in development Space Transportation System.
