Honeysuckle for the first few minutes of the moonwalk but the signal from Parkes was used for the reminder of the moonwalk. The role Parkes and Bolton played in the Apollo 11 moon landing was dramatised in the movie The Dish. Bolton would ensure Parkes would be involved in tracking for all the Apollo missions. Later years at Parkes and awards Bolton stepped down as Parkes director in 1971 to ease his administrative workload. While stepping down as director, Bolton continued pursuing science. For the remainder of his scientific career, he would focus on optical identifications of radio sources that were being surveyed by Parkes at 2.7 GHz. One significant result from this survey, when combined with previous low-frequency surveys, was Bolton's discovery of the peaked-spectrum source PKS B1934-638. Bolton was elected to the Royal Society of London and vice-president of the International Astronomical Union in 1973. Furthermore, he was awarded the Royal Astronomical Society Gold Medal in 1977 for his contributions to optical and radio astronomy. After a series of heart attacks, Bolton passed away in 1993.

The role of the director of the observatory (Cliff Buxton, played by Sam Neill) is based on John Bolton. Bolton had the asteroid 12140 Johnbolton named in his honour.
