The 64 meter (210 foot) antenna in Goldstone, California received its first signals from Mariner 4 on March 18, 1966. Mariner 4 was the first spacecraft to get a close look at Mars. Nicknamed the Mars station, the Deep Space Station (DSS) – 14 was upgraded to a 70 meter antenna in May 1988 in time to receive the very faint signals from Voyager-2’s encounter with Neptune. DSS-14 continues to receive signals from missions like Voyager 1, which entered into interstellar space in August 2012, about 12 billion miles away from the sun.
