<ul><li>The Orbital Debris Program Office (ODPO) logo includes a symbolic representation of two satellites colliding in low Earth orbit. The International Space Station appears at the bottom of the figure as it orbits the Earth. The NASA ODPO has taken the international lead in conducting measurements of the environment and in developing the technical consensus for adopting mitigation measures to protect users of the orbital environment.</li></ul>
