NASA’s Voyager-2 has been traveling through space for 43 years (and almost two years in interstellar space) and was completely alone since the last eight months in which contact was lost.
Fortunately, last week, some commands were sent to the spacecraft during a test and, after 34 hours and 48 minutes, the team received a greeting from deep space. Voyager 2 was still alive! The spaceship is perfectly and is capable of executing commands 18.8 billion kilometers from Earth.
The DSS4 antenna, Deep Space Station 43, is located in Canberra, Australia, and is part of NASA’s Deep Space Network, the collection of radio antennas used to communicate with spacecraft beyond the orbit of the Moon. The other two facilities are in Goldstone, California and in Madrid, Spain.
