STAY OR GO

I have a simple doubt. If it was the "future"Cooper who was sending those signals, ( both NASA coordinate details and STAY message); What does he actually want from the farmer Cooper- STAY at home or GO to NASA and start the mission? If he wanted Cooper (the Farmer) to “STAYâ€, then why is he also sending the coordinate details of NASA? If he really wanted Cooper (the Farmer) to STAY, the easiest way was to not sent those details about NASA location coordinates. And if he wanted Cooper (the Farmer) to GO with the mission, why did he sent a message to STAY? Please clear my doubt, because of this i feel like the Future Cooper is playing with the past, present and future of our poor Farmer Cooper. :) Thanks, Paul Varghese
