The space vehicle for this mission was tall, but had a stubby appearance since it had neither a CSM nor a launch escape system. Instead, the LM was housed within the spacecraft-lunar module adapter (SLA) at the top of the vehicle stack. The SLA, numbered as SLA-7, was just below the nose cap in the stack, and had four panels that would open once the nose cap was jettisoned in orbit, allowing the LM room to separate and move away.
