Since the Voyager space probes were launched in 1977, significant advancements in space exploration include the development of more sophisticated spacecraft, such as the Mars rovers (like Curiosity and Perseverance), which have conducted extensive geological and biological research on the Martian surface. The Hubble Space Telescope has provided unprecedented views of distant galaxies and cosmic phenomena, enhancing our understanding of the universe. Additionally, missions like New Horizons, which flew by Pluto in 2015, and the ongoing Artemis program aim to return humans to the Moon and eventually reach Mars, showcasing our growing capabilities in deep space exploration.
Almost nothing, weight is a force exerted due to gravity and since Voyager 1 is well outside the solar system there will be almost no gravitational force acting upon it.
The furthest satellite from Earth is the Voyager 1 spacecraft, launched by NASA in 1977. As of now, it is over 14 billion miles away and continues to transmit data back to Earth from interstellar space. Voyager 1 was originally designed for a mission to explore the outer planets but has since become a significant probe into the boundaries of our solar system.
Since 1969, there have been numerous advancements in space exploration, including the development of reusable spacecraft like the Space Shuttle, the launch of rovers to explore Mars, the construction and operation of the International Space Station, the landing of probes on asteroids and comets, and the successful flyby and exploration of Pluto by the New Horizons spacecraft. Additionally, private companies like SpaceX have emerged as key players in the industry, revolutionizing space travel with innovations such as reusable rocket technology.
Some notable space probes and achievements include: Voyager 1 and 2, which have left our solar system and are now in interstellar space. The Mars Curiosity rover, which has been exploring the surface of Mars since 2012. The New Horizons probe, which provided the first close-up images of Pluto and its moons. The Cassini spacecraft, which studied Saturn and its moons for over a decade before plunging into the planet's atmosphere.
It is also cheaper in many ways, since a human crew needs many things to stay alive including food, water, air, and bathroom and sleeping facilities. All of these require making a spacecraft bigger and heavier and therefore harder to get into space. You also do not have to have a return trip for an unmanned probe. A probe can be made to stay in space or on another planet and collect data until it stops working.
Voyager 1 holds the record for the space probe that has sent data back to Earth for the longest period. Launched in 1977, it is still communicating with Earth over 40 years later as it continues to journey into interstellar space.

Voyager is a spacecraft probe. It is not a satellite. NASA's twin Voyager spacecraft launched in August and September 1977. Voyager 1 focused on Jupiter and Saturn., while Voyager 2 flew past Jupiter, Saturn, Uranus and Neptune.
The most well-known probe to explore Jupiter is the Juno spacecraft, which has been studying the planet since 2016. Other past probes that have collected data on Jupiter include Pioneer 10, Pioneer 11, Voyager 1, Voyager 2, and Galileo.
The Cassini-Huygens probe is there now (Cassini orbiting Saturn since 2004, Huygens lander now inoperative, landed on the moon Titan). Earlier fly-bys of the planet were by Pioneer 11 (1979), Voyager 1 (1980), and Voyager 2 (1981).
Well, Voyager is now well beyond much useful gravitational influence of any of the solar system's planets. What we have learned is that planetary gravity wells can be used to provide a boost to passing spacecraft. Since Voyager most spacecraft to the outer planets spend some time in the inner system first, performing slingshots from one planet to the next to increase velocity. Each of these maneuvers robs a wee bit of the planet's angular momentum.
The Voyager 2 spacecraft is the only man-made object to have visited Neptune. It flew by Neptune in 1989, capturing close-up images and data about the planet and its moons. No other satellites or robots have been sent close to Neptune since then.

No, we have never sent any kind of probe to land on Saturn. This isn't possible, because the planet doesn't really have a solid crust for anything to sit on; thus the categorization 'gas giant'. Essentially, it is just a huge gas cloud surrounding a very dense metal core on the innermost part of the planet. However, there were several probes that did flybys of the planet and took pictures of it. Cassini was one of the more recent ones that took beautifully clear images of Saturn's rings; before that came Voyager, which was sent out of the solar system. Before we lost clear contact with the probe, it passed by and sent us information about the planet. But the Huygens probe has landed on Saturn's moon, Titan
