    4. tes due to their particularly large collision cross-sectional area. Because of their small diameter, tethers of a normal design may have a high probability of being severed by impacts with relatively small meteoroids and orbital debris. The resulting tether remnants may pose additional risks to operating spacecraft.


    5. Therefore, according to Forward and Hoyt [16], the criterion to evaluate the effectiveness of a de-orbit technique is not just whether it reduces orbital lifetime compared to atmospheric drag decay, but whether it reduces the product of orbital lifetime and collision cross-sectional area of the spacecraft, namely the ATP. As a matter of fact, Forward and Hoyt also demonstrated that the Terminator TetherTM can significantly reduce the ATP value for most LEO orbit

      good source for the same comment

    6. the orbital decay rate is large enough to compensate for the first effect and to greatly reduce the risk of the tethered system colliding with other spacecraft.

    9. However, although the performances of long tethers are attractive, the cost in terms of mass penalty, risk of arching and space debris impact might be too high for reliable operations.
