Despite being more than 47 years old, NASA’s Voyager 1 and Voyager 2 probes continue their historic mission in interstellar space. However, with dwindling power reserves, NASA engineers have made the challenging decision to deactivate the Cosmic Ray Subsystem (CRS) experiment on both spacecraft.
This strategic move aims to conserve energy, ensuring other critical instruments can remain operational.The CRS on Voyager 1 was deactivated on Feb. 25, 2025. Voyager 2’s CRS was deactivated on March 24, 2025.The probes have traveled approximately 29 billion kilometers from Earth, making them the most distant human-made objects in space.
According to NASA, Voyager 1 is now fully operational, with all four science instruments returning usable data to Earth after a period of technical challenges. The agency had previously turned off Voyager 1’s plasma science instrument years ago as of degraded performance.
The cosmic ray subsystem that was shut down on Voyager 1 is a suite of three telescopes designed to study cosmic rays, including protons from the galaxy and the Sun, by measuring their energy and flux.
Voyager Probes: Continuing Exploration Despite Power Challenges
Introduction
NASA’s Voyager 1 and Voyager 2 probes, launched over four decades ago, continue their historic journey into interstellar space. A critical challenge facing these distant spacecraft is the dwindling power supply. this Q&A article explores the Voyager missions, the impact of power constraints, and their ongoing scientific contributions.
Key Questions and Answers
How old are the Voyager probes, and how far have they traveled?
The Voyager 1 and Voyager 2 probes were launched in 1977, making them over 47 years old as of 2025.They have traveled approximately 29 billion kilometers from Earth, making them the most distant human-made objects in space.

Why are the Voyager probes shutting down instruments?
The Voyager probes are shutting down scientific instruments to conserve power. As the probes age, their power sources, radioisotope thermoelectric generators (RTGs), naturally produce less power. Deactivating instruments allows engineers to prioritize the operation of other critical components and extend the mission’s lifespan.

What is the Cosmic Ray Subsystem (CRS), and what does it study?
The Cosmic Ray Subsystem (CRS) is a suite of three telescopes designed to study cosmic rays. The CRS measures the energy and flux of cosmic rays, including protons from the galaxy and the sun. This data helps scientists understand the composition and origin of cosmic rays and the interstellar surroundings.

What are the Voyager probes’ primary mission objectives?
The Voyager missions were originally designed to explore the outer planets of our solar system: Jupiter, Saturn, Uranus, and Neptune. After completing these planetary flybys, the probes continued their journey, eventually entering interstellar space—the region between the stars.

how do the Voyager probes communicate with Earth?
The Voyager probes communicate with Earth using radio signals. Though, the vast distances involved mean that the signals are extremely weak and take a considerable amount of time to travel.
Summary Table
| Probe | Launched | Distance from Earth (approx.) | Current Status | Instrument Shut Downs |
|————–|———-|——————————–|————————————————————————————–|——————————–|
| Voyager 1 | 1977 | 29 billion km | Fully operational, 4 instruments active. | CRS (Feb. 25, 2025) |
| Voyager 2 | 1977 | 29 billion km | Continued its journey in interstellar space.| CRS (March 24,2025) |
Conclusion
The Voyager probes’ continued operation is a testament to the ingenuity of NASA engineers and the enduring human desire to explore the unknown. While power constraints present a meaningful challenge, the probes’ ongoing data collection continues to provide invaluable insights into the nature of interstellar space.
