The deflecting asteroid by dusting (DAD) mission addresses the challenges of deflecting a potentially hazardous asteroid (PHA) that has a large probability of impacting Earth. It is an innovative and mass-minimalist approach to exploit PHAs by using the dusting deflection method. This conceptual design is developed based on an asteroid space duster, which is a space miner that is equipped with dust mining equipment, path-finding systems, and robotic capabilities, that converts available materials into mining prospects. It also stores energy to power the space miner and produces thrust to deflect the asteroid. The primary goals of DAD are to use the dust-to-thrust dusting technique on a PHA and to characterize and measure the deflection caused by the dusting. The 99942 Apophis is used as the reference asteroid in the dust-to-thrust study to test the feasibility of using the approach for deflecting PHAs. There are currently no methods that continuously use the dust-to-thrust approach from an asteroid mining perspective in comparison to the existing deflecting asteroid concepts. This unsolved problem is the focus of the DAD-related study.

偏向小行星的除尘（DAD）任务解决了偏向具有很大可能性撞击地球的潜在危险小行星（PHA）的挑战。这是一种创新的，极简主义的方法，即通过使用粉尘偏转方法来开发PHA。此概念设计是基于小行星太空除尘器开发的，该除尘器是一种太空采矿器，配备了粉尘开采设备，寻路系统和机器人功能，可将可用的材料转换为采矿前景。它还存储能量为太空采矿者提供动力，并产生使小行星偏转的推力。DAD的主要目标是在PHA上使用灰尘推力除尘技术，并表征和测量由灰尘引起的变形。99942 Apophis在粉尘-推力研究中被用作参考小行星，以测试使用该方法偏转PHA的可行性。从小行星开采的角度来看，与现有的偏转小行星概念相比，目前没有方法可以连续使用尘土推力方法。这个未解决的问题是DAD相关研究的重点。
