Unmanned Mission
Apollo 6 (21)

Pad 39-A (2) 
Saturn-V AS-502 (2) 
High Bay 3 
MLP 2 
Firing Room 2 

Mission Objective

Demonstrate structure and thermal integrity and compatibility of launch vehicle and spacecraft; confirm launch loads and dynamic characteristics (Achieved)
Demonstrate separation of launch vehicle stages
(Achieved). 
Evaluate performance of emergency detection system in closed-loop configuration
(Achieved). Verify operation of Saturn V propulsion, guidance and control, and electrical systems. (Not Achieved. Due to early cutoff of two S-II stage J-2 engines and failure of S-IVB J-2 engine to restart.) 
Demonstrate performance of mission support facilities
(Achieved). 

Launch

April 4, 1968, 07:00:01 a.m. EST.
Launch Complex 37B, Eastern Test Range, Cape Canaveral FL. 

Orbit

Altitude: 222km Apogee, 163km Perigee
Inclination: xxx degrees 
Orbits: (orbital) 
Duration: Days, hours, min, seconds 
Distance

Landing

April 4, 1968, 05:23pm EST. Exact landing point unknown, first visual sighting at 27deg 40min North and 157deg 59min West. Capsule recovered by U.S.S. Okinawa and on board at 10:55 p.m. EST.

Mission Highlights

Apogee, 367 kilometers; perigee, 178 kilometers (nearly circular orbit intended, but early cutoff of S-II engines and overburn of S-IVB engine caused unplanned orbital parameters); after S-IVB engine failed to reignite, a 422-second burn of the SPS engine sent the spacecraft to an altitude of 22, 209 kilometers.
