Hello, I'm trying to complete a contract in which I need to measure the gravitational forces above 17,100 meters, 18,500 meters, and a couple places on the surface. I haven't tried to measure them on the surface yet because I wanna do the ones up high before I land. Anyway I believe the equipment to measure this is the GRAVMAX negative graviolie detector thing but when I go to log gravity data at altitude it says that that is unavailable at this time. When I click on it again the bubble for running the test has disappeared so it seems it has been cycled and I can still reset if I want but it doesn't count it towards the contract. I can't figure out how to fulfill this part of the contracts. I'm assuming I won't have a problem running the test on the ground while I'm stationary but I haven't tried yet. If anyone has some ideas or knows what I'm talking about advice would be helpful. Thanks. I'll try to get the name of the contract in a bit. I'm still cruising around finishing up other contracts now since I already flew to this side of the earth. Haha:)
