方玄昌有关 Saturn V／Shuttle 载重量的描述有很多误点。

He compared Saturn V and Shuttle's capacity and stated that the Saturn V's capacity had been 47000 kg, and the Shuttle's had been more than that. That is inaccurate. First, the 47000 kg is the payload delivered to the lunar orbit. The capacity for LEO orbit is 118,000 kg. Where shuttle's capacity is only 24000 kg.

Of course, if the shuttle orbiter itself is counted as payload, then, the apollo spacecraft should also be counted. That means the third stage of Saturn V should be counted as payload, and we have around 141,000 kg LEO capacity, still bigger than the shuttle system's 112,000 kg.

Saturn V is a big big rocket, and there has not been many use of it since the day of Apollo project. Just like people don't use an 18-wheeler to do pickup's job, Saturn V is rarely used.
