NASA has managed to keep all of Voyager 2's scientific instruments operating until 2026 by using a small reserve of backup power, postponing a shutdown planned for this year. Voyager 2 is the only spacecraft to have visited Uranus and Neptune, and its observations of Jupiter and Saturn were crucial in determining what topics subsequent missions should focus on. The spacecraft's power source is getting fainter, but NASA has managed to maintain enough power to keep the scientific instruments going by progressively switching off heaters, switching to backup thrusters, and shutting down other no-longer-needed systems.
NASA has extended the life of Voyager 2, which launched in 1977, by hacking a backup source of power, keeping the probe alive for another three years until 2026. Voyager 1 and 2 have traveled further than any other spacecraft and are currently in interstellar space. The probes have provided crucial scientific information during their 45 years of spaceflight, and their data is becoming more valuable as they travel further away from the sun. NASA has continually extended their missions, and the probes have exceeded expectations by sailing past the heliosphere.
China has successfully completed the first in-orbit test of a Stirling thermoelectric converter aboard the Tiangong-3 space station. The technology, which converts heat into electrical energy through a series of piston-driven magnets, is being investigated by NASA and is considered a technological solution to the challenges of space exploration. The Stirling power converter was developed by the Lanzhou Institute of Physics at the China Academy of Space Technology and could allow for long-duration stays on the moon and Mars when paired with a nuclear reactor as a power source.
