Using reaction control engines (RCEs), the CSM adjusted its alignment so that the top of the CM faced a funnel-shaped device in the LM called a drogue. The LM descent engine fired for 30 seconds at 19:08 UT, putting the craft into a descent orbit with a closest approach 14.5 km above the Moon's surface.
