Apollo 13 more immediate and visible warnings of anomalies. Because Apollo 13 followed the free-return trajectory, its altitude over the lunar far side was approximately greater than the orbital altitude on the remaining Apollo lunar missions. The Moon was almost at apogee during the mission (as it also was during the flights of Apollo 10 and Apollo 15), which also increased the distance from the Earth. The combination of the two effects ensures that Apollo 13 holds the absolute altitude record for a manned spacecraft, reaching a distance of from Earth on 7:21 pm EST, April 14, 1970.

Apollo program That was one of the biggest investment of the US in science, research and development, and employed thousands of American scientists. A single Saturn V launch in 1969 cost up to $375 million, compared to the National Science Foundation's fiscal year 1970 budget of $440 million. In 2009, NASA held a symposium on project costs which presented an estimate of the Apollo program costs in 2005 dollars as roughly $170 billion ($ in dollars). This included all research and development costs; the procurement of 15 Saturn V rockets, 16 command and service modules, 12 lunar modules, plus program support and
