The US space agency NASA had launched the Voyager 2 spacecraft in 1977. It remains one of the agency’s well-traveled spacecraft into space. It has, however, been unable to communicate with Earth since March this year. The spacecraft is believed to be wandering some 11.6 billion miles away from Earth. It entered interstellar space in 2018. Scientists for months upgraded the Deep Space Station 43 with the hope to re-establish communication with Voyager 2. According to NASA, scientists on October 30 sent commands to the spacecraft again. The agency claimed that after 34 hours and 48 minutes of round trip, a ‘hello’ came back.

Voyager 2 is the second spacecraft by NASA that has entered interstellar space. It is wandering between the stars and collecting data. Earlier, Voyager 1 was the only man-made object to enter into the region that is filled with gases, and elements. The Deep Space Station 43 is located in Australia. It is the only radio antenna available that can communicate with the Voyager 2. The station was being upgraded by NASA for the last eight months. It replaced some transmitters on DSS43 with powerful ones. The communication team then sent radio signals to check the hardware. Since the spacecraft is so far from the Earth, the team had to wait for over 34 hours for a reply.

Voyager 2 receiving and sending back a ‘hello’ brought cheer to the face of the team members. The communication means that the spacecraft has developed no problems and could send data back to Earth. The space agency uses the Deep Space Network to communicate with spacecraft and rovers in space. It has three huge telescopes. These telescopes are located in the United States, Australia, and Spain. According to NASA, the telescopes in the US and Spain are unable to communicate with Voyager 2. The telescope in Australia matches the spacecraft’s trajectory. The latest feat has bolstered the confidence of scientists that the hardware developed by them still can communicate with deep space probes.
