San Marco In 1962 NASA signed an agreement with the Centro Ricerche Aerospaziali at the University of Rome creating the San Marco program. The purpose of the program was to place an Italian satellite in orbit and to create an Italian equatorial launch site for the Scout rocket. Permission was obtained from Kenya to emplace two modified oil platforms off their coast, on the equator. The Santa Rita platform would serve as a launch control center and would also be used for launch of sounding rockets. The San Marco platform would be dedicated to launch of Scout rockets to orbit.
