NASA Astronauts Risked Their Lives to Capture Indonesia's Stray Palapa Satellite

Living in outer space is no simple feat. Astronauts are constantly faced with significant risks that can threaten their lives, ranging from limited oxygen and physiological changes due to zero-gravity environments to various other hazards originating from deep space. These risks escalate when unexpected events occur, as was the case for two NASA astronauts, Dale Gardner and Joseph Allen, in 1984. At that time, the American astronauts received news from Earth that two communication satellites had drifted out of orbit.

One of these was Indonesia’s Palapa communication satellite. Eight years earlier, in 1976, Indonesia launched its first communication satellite from Cape Canaveral, Florida, USA. The satellite successfully unified communication lines across the Indonesian archipelago. Unfortunately, several years after its initial launch, the satellite drifted from its intended orbit. This occurred because the rocket failed to push the satellite into the correct orbital path. Such a situation necessitated that the satellite be returned to its proper trajectory, one way or another.

The only solution was to capture the satellite manually using human effort. According to IFL Science, astronauts had to don specialised spacesuits and exit their spacecraft to capture the satellite before it returned to Earth. This meant the astronauts had to traverse the pitch-black void of space to reach the location of the Palapa satellite. The decision to exit the spacecraft was extremely high-risk, as the darkness of space holds many threats, from solar radiation to other cosmic hazards. Nevertheless, the mission had to proceed, and Dale Gardner and Joseph Allen were tasked with the mission to capture Palapa.

“Allen and Gardner eventually exited into zero gravity to begin the spacewalk portion of the satellite capture,” NASA stated. Allen exited the spacecraft using a specialised suit equipped with tethers to the vehicle. He then floated towards the Palapa satellite, which was at risk of drifting aimlessly. Upon arrival, he attached a type of cable connected to the spacecraft. Meanwhile, Gardner remained on the spacecraft, waiting for the satellite’s arrival. His role was to ensure the satellite was locked and positioned precisely within the payload bay. Both worked under the supervision of another astronaut remaining inside the vehicle.

ortunately, after 5 hours and 42 minutes, both astronauts successfully completed the task. The operation proceeded without major hindrance, and both Allen and Gardner emerged safe. The Palapa satellite was ultimately able to be brought back into a controlled state.
