Apollo (spacecraft) Surface Experiment Packages ALSEP, the modularized equipment transporter (MET) (a hand-pulled equipment cart used on Apollo 14), the Lunar Rover (Apollo 15, 16 and 17), a surface television camera, surface tools, and lunar sample collection boxes. The ascent stage contained the crew cabin, instrument panels, overhead hatch/docking port, forward hatch, optical and electronic guidance systems, reaction control system, radar and communications antennas, ascent rocket engine and propellant to return to lunar orbit and rendezvous with the Apollo Command and Service Modules. The spacecraft–LM adapter (SLA), built by North American Aviation (Rockwell), was a conical aluminum structure which supported the service
Apollo 6 spacecraft only entered the atmosphere at a speed of instead of the planned of a lunar return. However, this had been demonstrated on Apollo 4. Ten hours after launch, it landed from the planned touchdown point in the North Pacific Ocean north of Hawaii, and was lifted on board the USS "Okinawa". The S-IVB's orbit decayed three weeks later, and it reentered the atmosphere on April 25, 1968. Although Apollo 6 did not reach full translunar velocities in either direction, it was considered successful enough to fly astronauts on the next Saturn V, which in addition was tasked to send
