NASA's spinning spacecraft studying the satellites of the solar system's largest celestial body (aside from the sun), may already be switched off, but the space agency won't say.
The Juno probe launched in 2011 and entered orbit around Jupiter in 2016, beginning what was originally planned as a 20-month mission. Nearly a decade later, the spacecraft has delivered unprecedented research of the Jovian system, observing the gas giant, its many moons and faint ring system long past its intended lifespan.
