ARLA/CLUSTER: Voyager 1 e 2: Ainda estão operando após 40 anos nas profundezas do espaço

[João Costa > CT1FBF]

Space 1977

Voyager 1 and 2: Still operating after 40 years in the depths of space.

Voyager 1 is currently some 20 billion kilometres from Earth
travelling at 15.5 kilometres a second. It takes 19 hours for a signal
from the spacecraft's 20 watt transmitter to reach home.

Voyager 2 is 17 billion kilometres away and will soon leave the Solar System.

Launched in 1977, the twin spacecrafts have explored the giant planets
and their strange moons, investigated the boundary of the Solar System
and changed how we see our place in the Universe. The probes even
carry a message for aliens in the form of a golden record.

Retired NASA astronaut Ron Garan meets many of the original team still
working on the mission, nursing the twin spacecraft through their
final years.
