Voyager 2 Gets a Power Boost to Keep Exploring

Topic: Space

NASA engineers found a way to save power on Voyager 2, allowing it to continue its scientific work for longer. The effort, called the 'Big Bang,' was led by engineers at NASA's Jet Propulsion Laboratory. This will give the spacecraft more time to explore space.

NASA engineers have found a solution to help Voyager 2 conserve power and keep working. The team at NASA's Jet Propulsion Laboratory came up with an idea called the 'Big Bang.' They shut down some parts of the spacecraft that used too much energy and replaced them with more efficient ones.

Voyager 2 relies on a special device called a radioisotope thermoelectric generator (RTG) to produce electricity. This device uses heat from decaying plutonium to generate power. However, as the plutonium supply decreases, Voyager 2 loses about 4 watts of power every year. After nearly 50 years in space, the spacecraft has very little power left.

To save energy, mission controllers had to turn off some science instruments on Voyager 2 and its twin, Voyager 1. The team was able to switch off two more instruments on each spacecraft since 2024. Without the 'Big Bang' effort, they would have had to shut down another instrument on Voyager 2 by the end of 2026.

Why It Matters

This achievement is important for India because it shows how scientists can work together to solve complex problems and extend the life of spacecraft that are helping us learn more about our universe. It also highlights the importance of space exploration in understanding our place in the world.

Key Facts
