NASA Revives Voyager 1’s Roll Thruster After Long Silence

NAVSA has successfully revitalized the Roll Thruster aboard the Voyager 1 spacecraft, a component that had been inactive for nearly two decades. It’s quite surprising, considering it was thought to have failed back in 2004.

The significance of this revival is heightened by concerns that the primary thrusters on Voyager may be developing some buildup that could lead to clogs, potentially causing them to fail by the fall of 2025.

Recently, NASA astronauts faced a challenge while attempting to dock a Boeing Starliner with the International Space Station, which could add some context to the intricacies of space missions.

On another note, NASA keeps its Earth antennas, crucial for communicating with both Voyager 1 and its sibling Voyager 2, offline for several months. The Australia-based Deep Space Station 43, which boasts a 230-foot-wide dish, will remain inactive until February 2026 due to necessary upgrades.

Despite the upgrades, the inability to communicate with these twin probes raises some concerns within the scientific community.

Suzanne Dodd, who manages the Voyager Project at NASA’s Jet Propulsion Laboratory in California, notes the importance of these upgrades not just for Voyager but for future lunar missions as well. She mentioned that enhancing communication with deep-space missions is partly built on insights gained from Voyager’s journey.

Each Voyager spacecraft is equipped with primary thrusters that allow for multidirectional movement, along with a smaller roll control thruster. This smaller thruster plays a critical role in maintaining orientation so that the antennas can remain targeted toward Earth.

Voyager already reported bringing another set of thrusters online in 2018 and 2019. However, if Voyager were to lose its communication link with Earth, reestablishing that connection could be nearly impossible.

Launched in 1977, Voyager 1 has traveled almost 15 billion miles and is now traversing interstellar space, far beyond our solar system. Its findings have included landmark discoveries, such as identifying a thin ring around Jupiter and observing previously unrecorded moons orbiting the massive planet. Voyager has also expanded our understanding of Saturn by discovering new moons and rings.
