Designation: Apollo S1 L AS(B)-2
Description: 2nd Apollo Saturn C-1 boilerplate CM orbital

Decay Date: 1964-09-22
USAF Sat Cat: 883
COSPAR: 1964-057A
Apogee: 215 km (133 mi)
Perigee: 181 km (112 mi)
Inclination: 31.7000 deg
Period: 88.50 min

The mission was intended to demonstrate:

  1. spacecraft launch vehicle compatibility,
  2. launch and exit parameters to verify design, and
  3. the alternate mode of escape-tower jettison (i.e., using the launch escape and pitch control motors).

The launch azimuth was again 105 degrees. The S-1 stage shut down at T+147.4 seconds, only 0.7 second later than planned. The S-1 and S-IV stages separated at T+148.2 seconds, and the S-IV stage ignited 1.7 seconds after that. The launch escape tower was jettisoned at T+160.2 seconds. S-IV cutoff took place at T+621.1 seconds, burning l.3 seconds longer than anticipated. The spacecraft and S-IV were inserted into orbit at 631.1 seconds (2.0 seconds late), at a velocity of 7,810.05 meters (25,623.54 feet) per second. The spacecraft weight at insertion was 7,815.9 kilograms (17,231 pounds). Orbital parameters were 212.66 and 226.50 kilometers (114.85 and 122.37 nautical miles), and the period 88.64 minutes.

All spacecraft test objectives were met. Satisfactory engineering data verified the launch and exit design criteria. The launch escape and pitch control motors moved the launch escape system safely out of the path of the spacecraft. The Manned Space Flight Network obtained telemetry data into the fifth orbit, at which time the transponders stopped working, but several stations continued to track the vehicle until it reentered over the Indian Ocean on its 59th journey around the earth. As with BP-13, no recovery of the spacecraft was planned.
