The 29 October, NASA has confirmed mission operators could send a series of commands to the Voyager spacecraft 2 who has been exploring space since 43 years. Voyager 2 was offline since March, while the only radio antenna capable of sending commands to the spacecraft was down during upgrades. The branch is located in Canterbury, in Australia, and is known as the Deep Space Station 43.

The antenna measures 70 meters wide and has been offline for repairs and upgrades since mid-March. After sending the signal on 29 October, Voyager 2 returned a signal to confirm that it had received the signal and executed the commands without problem. The call sent to Voyager 2 was a test of new hardware recently installed on Deep Space Station 43.eval(ez_write_tag([[250,250],’troyes_obs_fr-box-3′,'ezslot_0′,131,’0′,’0′]));

The satellite is part of the NASA Deep Space Network, a collection of radio antennas from around the world used to communicate with spacecraft operating beyond the moon. Since the massive antenna was offline, mission operators were able to receive health updates and scientific data from Voyager 2, but were not able to send commands to the probe.

Voyager 2 was launched in 1977 and has traveled billions of miles so far. Among the antenna updates are two new radio transmitters. One of these transmitters is used to talk to Voyager 2 and had not been replaced for over 47 years. Engineers also upgraded the heating and cooling equipment, power supply equipment and other electronic components required to operate the new transmitter.

NASA says the successful call to Voyager 2 indicates that the disc will be back online in February 2021. The DSN project manager, Brad Arnold, says that what made the upgrade task unique, is that the work has been done at all levels of the antenna from the pedestal. down to the feed cones suspended above the dish.
