-This strategy requires a thruster firing solution which creates this desired :math:`{}^{\mathcal{B}}{\Delta}\boldsymbol H` over the duration of the momentum dumping.  The goal of the RW momentum management module is to simply compute if a :math:`{}^{\mathcal{B}}{\Delta}\boldsymbol H` is required, or set it equal to zero if the RW momentum is too small.  Not that this module will only compute :math:`{}^{\mathcal{B}}{\Delta}\boldsymbol H` once.  Either it is zero or non-zero.
