Some considerations in support of solid propulsion for space debris disposal.

Some considerations on the use of solid rocket motors for space debris disposal are presented. From the synthesis of a de-orbit sample mission and a tradeoff study on costs and benefits, a solid propellant unit for end-of-life missions and debris in-space disposal missions is evaluated. The enhanced operation flexibility, the propellant development and an advanced ignition concept granting multiple and independent firing capability of a new solid propulsion concept are discussed.
