NASA-created illustration of the trajectory and orbit of the <a href="https://en.wikipedia.org/wiki/Wilkinson_Microwave_Anisotropy_Probe" class="extiw" title="en:Wilkinson Microwave Anisotropy Probe">Wilkinson Microwave Anisotropy Probe</a>. "This diagram shows the WMAP trajectory and orbit pattern around the second Lagrange Point (L2). The travel time to L2 for WMAP was 3 months, including a month of phasing loops around the Earth to allow a lunar gravity-assisted boost."
