NASA lost contact with Voyager 2 on July 21, after certain commands changed the spacecraft's orientation, causing its antenna to point two degrees away from Earth. As a result, its signals couldn't reach ground systems and operators couldn't send signals to reposition the spacecraft. Fortunately, on July 31, NASA detected a faint "carrier signal" from Voyager 2, confirming it is still operating.
