Near Earth Asteroids (NEAs) pose as great of a threat as ever. This thesis looks into one innovative way of mitigating such threats through painting the surface of an asteroid such as Apophis using triboelectric dispensers, i.e. a space powder tube. Through the change of surface reflectivity from painting the surface white or black, the thermal distribution on the surface is thus changed which incurs a change in photon momentum radiation. This effectively creates a force which pushes the asteroid in a direction that alters its orbit to miss an Earth collision trajectory, i.e. altering the…mehr

Produktbeschreibung
Near Earth Asteroids (NEAs) pose as great of a threat as ever. This thesis looks into one innovative way of mitigating such threats through painting the surface of an asteroid such as Apophis using triboelectric dispensers, i.e. a space powder tube. Through the change of surface reflectivity from painting the surface white or black, the thermal distribution on the surface is thus changed which incurs a change in photon momentum radiation. This effectively creates a force which pushes the asteroid in a direction that alters its orbit to miss an Earth collision trajectory, i.e. altering the Yarkovsky effect. This thesis looks into the experiments and simulations necessary for constructing such a payload. The first mission implementing this design will be launched by 2020 to the NEA Apophis as the first test of this payload while a flight test in low earth orbit (LEO) will be conducted before then to confirm the operational status of the payload.
Autorenporträt
Shen Ge received his Masters in aerospace engineering from Texas A&M University in 2011 August and received his undergraduate with a dual major in aerospace engineering and physics with Magna Cum Laude in 2008 December from Georgia Institute of Technology. His background is in space design, space simulations, and experimental design.
