Levitation
The first electrostatic levitator was invented by Dr. Won-Kyu Rhim at NASA's JPL lab in 1993. A charged sample of 2 mm in diameter can be levitated in a vacuum chamber between two electrodes positioned vertically with an electrostatic field in between. The field is controlled through a feed back system to keep the levitated sample at a predetermined position. Several copies of this system have been made in JAXA and NASA, and the original system has been transferred to Callifornia Institute of Technology with an upgraded setup of tetrahedra four beam laser heating system.
On the Moon the photoelectric effect and electrons in the solar wind charges fine layers of moon dust on the surface forming an atmosphere of dust floating in "fountains" over the surface of the moon.
