MSC forwarded a plan for the Apollo 15 Lunar Surface Science Project to NASA Hq.

The plan provided for replacement of the ALSEP Array A-2 central station and lunar geological equipment, along with rework of the Passive Seismic Experiment. Total cost of the project was estimated at $6.7 million excluding the cost of surveying instrument and instrument staff. With a May 15 go-ahead, delivery could be made by one year from that date. Apollo Program Director Samuel C. Phillips in a message to MSC Director Robert R. Gilruth approved the plan, saying that a June 1, 1970, delivery of the array would be acceptable and requesting procurement action leading to a definitive Bendix contract be submitted by June 20, 1969.
