Nobody can build a kilogram-scale inertial balance of sufficient absolute precision. If we knew how, we'd be doing it. Also, the ISS is a tricky place to work

Nobody can build a kilogram-scale inertial balance of sufficient absolute precision. If we knew how, we'd be doing it.
Also, the ISS is a tricky place to work for a precision measurement. It's electrically, seismically, and gravitationally noisy (and huge gradients). Precision gravitational measurements are generally carried out in dedicated spacecraft with careful attention to those concerns, if they can't be done on the ground.
- rmrfrmrf 13y agoServes me right for acting like a know-it-all. Kinda glad I did, though, because you gave me a lot of good information. Thanks!
- CamperBob2 13y agoMost people don't realize that the gravity on ISS is almost as strong as it is on the surface of the Earth. They're continuously falling toward Earth, going just fast enough to miss the ground.
- ronaldx 13y agoGravitational acceleration is approx 10% less? Based on the radius of the earth and the radial distance of the ISS.
