Artist’s concept of Voyager I (Source: NASA)<\/p><\/div>\n

Yesterday, while listening to the BBC World Service, I heard this fascinating documentary focusing on the Voyager I and II spacecraft. It absolutely blows my mind that both of these spacecraft have been operating for 40 years and continue to send signals back to Earth. Talk about weak signal DX!<\/p>\n

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\u00a0the spacecraft’s 20 watt transmitter to reach home. Voyager 2 is 17 billion kilometres away and will soon leave the Solar System.<\/span><\/span><\/p>\n

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.<\/p>\n

Retired NASA astronaut Ron Garan meets many of the original team still working on the mission, nursing the twin spacecraft through their final years.<\/p>\n<\/blockquote>\n
