An old man drives up to the
Parkes Radio Telescope to admire the dish. A technician gently cautions him that he has driven in through "the old entrance" and is therefore trespassing. Requesting that the man leave immediately, the technician encourages him to visit the observatory's nearby visitor centre and take the tour, as the dish has seen some amazing times. The old man thoughtfully agrees. The movie flashes back to July 1969, days before the launch of
Apollo 11.
NASA anticipates using the dish as a primary receiving
antenna for the video transmission of
Neil Armstrong's
historic first steps on the Moon. The dish's staff, Mitch, Glenn, and their boss, Cliff (the old man from the prologue) have been assigned a liaison by NASA, Al Burnett. Mitch resents Al, as he feels that Al is condescending; and that his presence likewise reflects a wider perception among NASA that the Australians are incompetent and unreliable. Cliff chastises Mitch for his hostility, explaining that Al's presence is justified, and that he and NASA merely want to ensure that the
Moon landing proceeds as smoothly as possible. The major role that the dish is set to play in the Moon landing draws great interest upon the sleepy town of
Parkes from major dignitaries, including
the U.S. Ambassador and
the Prime Minister. Parkes mayor, Bob, is delighted, as he played a key role in securing the dish's construction at Parkes, and thus the dish's prominent role in the Moon landing will be a boon to his political career. A power cut strikes Parkes. The dish's backup generator fails, as Mitch had previously conducted a maintenance procedure on it incorrectly. When the mains power returns, the station's tracking computers have been wiped of all their programming, and the dish can no longer locate
Command Module Columbias signal in space.
Houston notices that they are no longer receiving any information from the Parkes station and queries them about the problem. Fearing that NASA may demote the team's role in the Moon landing if it learns of the mistake, Cliff falsely responds that the dish is receiving a clear signal from the spacecraft. Al reluctantly corroborates the lie. Mitch confesses his own culpability to Al, who immediately forgives him, mending their strained relationship. The four men work together to try to relocate Apollo 11's signal. After several hours and mishaps, they are able to lock on to the spacecraft's signal with minutes to spare before their scheduled shift as Apollo 11's main receiver begins, thus ensuring their mistake has gone undiscovered. After the
Lunar Module Eagle makes a successful landing upon the Moon, Cliff notes with concern that the wind seems unusually strong. Regulations state that if the wind reaches 30 knots, the dish must be "stowed", meaning it can not be pointed at the Moon, and thus will not be able to receive
Eagles video broadcasts. Events conspire such that the Parkes dish becomes the only antenna on Earth capable of receiving the historic video footage of Armstrong's first steps upon the Moon. The wind reaches and exceeds 30 knots. Despite risking the total collapse of the dish, and therefore, their own lives, all four members of the dish team opt to keep the dish pointed at the Moon, adamant that allowing the world to witness and record the first moonwalk is worth the risk. The world watches in silent awe as man sets foot upon the Moon. As the Prime Minister, the ambassador, and Parkes dignitaries watch the moonwalk together, Bob is informed that the video feed is coming from the dish. Everybody is delighted, and the Prime Minister toasts Parkes. As the moonwalk concludes, the dish staff congratulate one another. Back in the present day, the technician once again insists that Cliff must leave. Cliff solemnly takes one last look at the dish before returning to his car. Before he leaves, the technician remarks that Cliff seems familiar, suggesting that Cliff's legacy is immortalized within the observatory's visitor centre. A title card explains that the dish withstood winds of over 60 mph (52 knots) to deliver the video footage of man walking on the Moon. ==Cast==
