NASA fixed a remote link to the 46-year-old Voyager 1 space probe on Monday, according to an update from the agency.

The probe had been sending “gibberish” code back to NASA because of a broken chip, according to a report by the Guardian. Given the distance, NASA was not able to repair the chip but rearranged the probe’s code so that it could send usable data, a challenge given the spacecraft’s limited 70-kilobyte memory.
