"The millimeter-sized orbital debris objects represent the highest penetration risk to the majority of operational spacecraft in low Earth orbit (LEO). The SDS mission will serve two purposes. First, the SDS will collect useful data on small debris at the ISS altitude. Second, the mission will demonstrate the capabilities of the SDS and enable NASA to seek mission opportunities to collect direct measurement data on millimeter-sized debris at higher LEO altitudes in the future – data that will be needed for reliable orbital debris impact risk assessments and cost-effective mitigation measures to better protect future space missions in LEO."
