Voyager
Shortly after the Pioneers made their flybys, the Voyager1 and Voyager 2 probes followed. They made many important discoveries aboutJupiter and Saturn, including rings around Jupiter and the presence ofvolcanism on Jupiter's moon, Io. Voyager went on to make the first flybys ofUranus, where it discovered 10 new moons, and Neptune, where it found thatNeptune actually weighs less than astronomers thought. Both Voyager crafts have enough power to keep transmitting radio signals until at least 2025, and are now exploring the very edge of the solar system and beginning of interstellar space. Voyager 2 is currently the farthest man-made object from Earth, at more than a hundred times the distance from the Earth to the sun, and more than twice as far as Pluto.

However, the other options insist that they are recording data and observing, like you would do when performing an experiment. I hope this helps! :)
