NASA spacecraft shuts down to get energy to continue

Anh Vũ |

NASA's Voyager 2 spacecraft has had to turn off some of its scientific equipment to conserve power after 47 years of traveling in space.

NASA has just decided to turn off one of the scientific instruments on the Voyager 2 space probe to save energy.

Voyager 2, launched in 1977, is part of NASA's Voyager program to explore the planets in our solar system and push the boundaries of space. The spacecraft has passed by Jupiter, Saturn, Uranus and Neptune, collecting unprecedented images and data about these planets.

Voyager 2 has now entered interstellar space, the region where the Sun's influence is almost gone. This event is a milestone in the history of space science, with Voyager 2 becoming one of the first two spacecraft to cross this border, along with Voyager 1.

As the power from the RTG (radioactive decay heat generator) system runs out, NASA must plan to shut down each device to extend the life of Voyager 2.

NASA engineers have carefully chosen to shut down less critical equipment, leaving only the essential equipment to continue collecting data. NASA hopes that shutting down this equipment will allow Voyager 2 to maintain a signal with Earth for a few more years.

The spacecraft is now more than 19.9 billion kilometers from Earth, continuing its journey through interstellar space - the furthest region humans have ever explored. Even with its equipment turned off, Voyager 2 can still transmit scientific data back to Earth.

This decision reflects careful calculations to optimize operational time, maintain the historic mission of exploring the universe, and collect data on the remote and unknown space environment.

Voyager 2 continues to send data about the interstellar environment, giving scientists a clearer view of the universe and a deeper understanding of the boundary between the solar system and outer space. This is a long-term mission that not only expands humanity's understanding of the universe but also lays the foundation for future deep space exploration missions.
