The concrete foundation placed Dec. 18 (foreground) for Stennis Space Center's future A-3 Test Stand has almost completely cured by early January, according to Bo Clarke, NASA's contracting officer technical representative for the foundation contract. By late December, construction on foundations for many of the test stand's support structures - diffuser, liquid oxygen, isopropyl alcohol and water tanks and gaseous nitrogen bottle battery - had begun with the installation of (background) `mud slabs.' The slabs provide a working surface for the reinforcing steel and foundation forms.
