// the signal · what the data says
Humanity has a handful of active deep-space probes. The Voyagers, in interstellar space since 2012/2018, are the farthest human objects and are slowly losing power. The current science frontier is ocean worlds — Europa Clipper (2024) and JUICE are en route to Jupiter. Positions can be read live from JPL Horizons.
