Voyager 1 Resumes Contact After 48-Hour Communications Gap

Voyager 1 resumed contact with Earth on October 20, 2026, after missing check-ins on October 18 and 19, according to the report.

Key details

• The report says a group of Voyager 1’s thrusters went offline and the spacecraft switched to backup thrusters.
• Engineers had not determined the cause of the communications loss at the time of the report.
• Launched in 1977, Voyager 1 operates in interstellar space.
• The spacecraft was projected to be 16.09 billion miles (25.89 billion kilometers) from Earth on November 18, 2026, nearly one light-day away.
• A power-saving reconfiguration in early September 2026 switched off three devices and replaced them with three lower-power alternatives.

Voyager 1’s signal reappeared on October 20, 2026, after about 48 hours without contact.

Why it matters

Voyager 1’s distance means its signal takes nearly a day to travel one way between the spacecraft and Earth. The reported power-saving changes and use of backup thrusters show how engineers are managing a spacecraft launched nearly five decades ago.
