DSS43 is part of the larger Deep Space Network that ensures all spacecraft outside the Moon can communicate with each other as long as there is a line of sight towards Earth. However, this dish is the only dish that can communicate with Voyager 2. The craft is so far (11.6 billion miles) that the Northern Hemisphere antenna can not communicate, and DSS43 is the hemisphere dish that is enough only for the South strong. strong to send orders.
Upgrades will be crucial to not only the Voyager 2 when the dish officially returns in February 2021. NASA hopes their Perseverance aircraft will land on Mars on February 18 and DSS43 has can play an important role in that mission. It could also be important for upcoming missions on the Moon and ultimately crew trips to Mars. The money NASA invested now could easily pay dividends for decades of future space exploration.
