Cool stuff - though they seem to be talking about silicon substrates (eventually), not thinned silicon chips on aluminum.

 * First sprites, 10g 3.8 cm square (1.5 inch)
  * 6.88 kg/m^2^ ( 5 gram thinsats, 0.028m^2^, 0.18 kg/m^2^)
 
 * Dr. Peck speculates:  eventually 20μm thick and 7.5mg, 60μm/s^2^
  * 4.5e-10 Newtons
  * Light pressure is 1367W/m^2^ / 2.998e8 m/s -> 4.56e-6 N/m^2^
  * approx 1e-4 m^2^ -> 2e-9 m^3^ -> 3750 kg/m^3^  
  * ballistic coeff 0.0375 kg/m^2^

 * Lorentz force, charging the chipsats then deflecting in magnetic field
