Apollo 4 - Space launch mission detailed information
Apollo 4 4
9 NOV 1967
National Aeronautics and Space Administration
Launch Complex 39A
Apollo 4 was an "all-up" test, meaning all rocket stages and spacecraft were fully functional on the initial flight, a first for NASA. It was the first time the S-IC first stage and S-II second stage flew. It also demonstrated the S-IVB third stage's first in-flight restart. The mission used a Block I Command Service Module (CSM) modified to test several key Block II revisions, including its heat shield at simulated lunar-return velocity and angle.
The Saturn V was a human-rated expendable rocket used by NASA between 1967 and 1973. Most notably, the Saturn V took the Apollo program to the Moon. It still remains the world's tallest, heaviest, and most powerful rocket ever brought to operational status and is the only launch vehicle to take humans beyond LEO.
