Memorandum from Thomas Gold to F Drake and F A Long Regarding a telephone conversation with G Mulders. Says that he talked to Mulders who is keen to take on Arecibo [Ionospheric Observatory] contracting. Also says that he thinks that the NSF [National Science Foundation] will respond positively if they can persuade ARPA [Advanced Research Projects Agency] to ask the NSF to take over the operation of the contract. Says that they should press ARPA to make this change. Thinks that the present time is a good time to do so because ARPA are trying to find a way of decreasing their commitment to them.
