 A Multifunctional Paintball Cloud (MPC) method for asteroid deflection

 *

 *ABSTRACT:*

 There is an increasing interest in studying near-Earth asteroids (NEAs),
to minimize their threats to the Earth as well as to make use of their
potentially useful resources. There have been several asteroid flybys near
the Earth and a meteor blast in Russia; on the other hand, two U.S. firms,
Planetary Resources and Deep Space Industries, have announced their plans
to send private missions to mine asteroids.

The Multifunctional Paintball Cloud (MPC) method tries to alter an
asteroid’s trajectory by combining two kinds of traditional asteroid
deflection methods: short-term momentum transfer (kinetic impact) and
long-term momentum transfer. The paintballs containing white paint powder
first transfers their momentum upon the impact, and the released paint
alters the albedo of the asteroid’s surface, increasing solar radiation
pressure and deflecting the asteroid’s path over a long time.

 This idea has been submitted to the 2013 NASA Innovative Advanced Concept
(NIAC) solicitation, and a Step B proposal is currently being drafted. The
presentation will discuss the mission concept, possible applications, and
experiment plans.
