Are there attempts to test MOND on a much smaller scale than observing galaxies? Is it possible to generate and measure such a small acceleration (a0, pic related) on Earth or in the solar system? Is it possible to accelerate a small Asteroid (in the order of 10,000,000,000 kg) with a 1N ion thruster for a long time, let observatories track the trajectory and see if it accelerates slower than predicted by Newton?
