The LESS would be equipped with a flashing light and VHF radio beacon to simplify tracking from the CSM. On reaching the rendezvous point the CSM pilot would dock with the LESS using the same docking probe that was used to dock with the LM, and a special attachment on the front of the LESS. This would require some skilled flying on the part of the pilot, as any use of the front-facing RCS jets could present a serious hazard to the astronauts on the LESS if the hot exhaust gases hit them.
