Apparatus and methods for orbital debris removal

摘要

An orbital debris interception vehicle includes a satellite bus and a debris interception module releasably coupled to the satellite bus. The debris interception module includes a debris impact pad, such as a pancake-shaped Whipple shield. A plurality of such vehicles can be deployed into an equatorial orbit and maneuvered to intercept orbital debris as it passes through the equatorial plane. In particular, the satellite bus can release the debris interception module before an intercept and reconnect to it after the intercept.

1. A method of intercepting orbital debris, comprising:
communicating with a satellite constellation including a plurality of orbital debris interception vehicles in an equatorial orbit, each orbital debris interception vehicle comprising:
a satellite bus; anda debris interception module releasably coupled to the satellite bus, wherein the debris interception module comprises a debris impact pad; wherein communicating with the satellite constellation further comprises:
receiving equatorial crossing data for a debris object and an active spacecraft;identifying a closest orbital debris interception vehicle to an equatorial crossing point of the debris object;commanding at least one of the satellite bus and the debris interception module of the closest orbital debris interception vehicle to the equatorial crossing point of the debris object to maneuver such that the debris impact pad of the debris interception module of the closest debris interception vehicle to the equatorial crossing point of the debris object is at the equatorial crossing point of the debris object;commanding the closest orbital debris interception vehicle to the equatorial crossing point of the debris object to release the debris interception module;after the debris object has collided with the debris interception module, commanding the closest orbital debris interception vehicle to the equatorial crossing point of the debris object to reattach to the debris interception module;identifying a closest orbital debris interception vehicle to an equatorial crossing point of the active spacecraft; andcommanding at least one of the satellite bus and the debris interception module of the closest orbital debris interception vehicle to the equatorial crossing point of the active spacecraft to maneuver such that the active spacecraft will not collide therewith.
