Voyager 2’s three surviving instruments are part of humanity’s only direct scientific presence in interstellar space—and with no approved successor under development, engineers remotely reconfigured the 49-year-old probe’s power system in July 2026, completing a delicate operation across a 39-hour command-and-response delay that should preserve its science for at least another year.
JPL's management contract is suddenly up for grabs for the first time since the 1930s, and NASA's own language shows why this is more than a routine procurement fight
Voyager 2 is nearly 50 years old, losing about 4 watts of power every year as its plutonium power source fades — and NASA just bought it at least another year of science with an all-at-once power-system swap engineers called the “Big Bang,” performed on a spacecraft with razor-thin power margins and no possibility of physical repair.
Scientists thought Titan was hiding a global ocean beneath its frozen crust. But a 2025 reanalysis of Cassini data points to something stranger instead — a roughly 380-kilometre-thick layer of slushy ice, close to melting and likely threaded with pockets of liquid water that could reach 20°C near the rocky interior.
