4. The Failure of the Soviet Zond Program and the Decision to Gamble on Apollo 8. Bob Zimmerman discusses the fierce moon race with the Soviet Union's Roscosmos, which utilized the Zond capsule for circumlunar missions. Zond 5 and 6, launched in late 1968, suffered critical failures (guidance system and atmosphere loss, respectively), forcing the Soviets to cancel their planned manned December flight. Watching this, NASA manager George Low realized the Lunar Module (LM) for Apollo 8 was behind schedule. To maintain the initiative and potentially win the space race, Low and Sam Phillips made the aggressive decision to send Apollo 8 to the moon without the LM "lifeboat." They informed NASA boss James Webb after the decision was finalized. Webb, though initially upset, accepted the decision, betting that the engineering was sound enough to risk the mission in order to prove the US was superior.
