Cassini Huygena
The Cassini spacecraft, launched in October 1997, traveled approximately 3.5 billion kilometers (2.2 billion miles) to reach Saturn. Its average speed varied throughout the journey due to gravitational assists and orbital maneuvers, but it generally averaged around 21,000 kilometers per hour (about 13,000 miles per hour). The spacecraft entered Saturn's orbit in July 2004 after a nearly seven-year journey.
There have been four spacecraft that have visited Saturn. The first was 'Pioneer 11', which was launched on April 5th, 1973. In August of 1977, 'Voyager One' and 'Voyager Two' were both launched to begin their mission to Saturn. 'Voyager One' flew by Saturn on November 1980 and, 'Voyager Two' reached Saturn in the summer of 1981. On October 15, 1997, a European spacecraft, called the Cassini-Huygens was the last to explore Saturn. A fifth spacecraft will be launched from the Cassini called the Huygens probe. This smaller probe was sent to to explore Saturn's largest moon, Titan.
In 2000, the ECM (Electromagnetic Cassini Magnetometer) was part of the Cassini spacecraft, which was launched to study Saturn and its moons. During its mission, Cassini entered orbit around Saturn in July 2004, allowing it to closely investigate the planet's magnetic field and other phenomena. By 2000, however, the spacecraft was still in its early development and preparation stages, as it had not yet launched.
It was launched on October 15, 1997 and entered into orbit around Saturn on July 1, 2004.
The Cassini spacecraft is the only spacecraft to have visited Saturn. It orbited the planet from 2004 to 2017, providing valuable data and images of Saturn and its moons.
Saturn was last visited by NASA's Cassini spacecraft, which entered the planet's orbit in 2004 and conducted extensive observations until its mission concluded in September 2017. During its time at Saturn, Cassini provided invaluable data about the planet, its rings, and its moons. The spacecraft's final act was a deliberate plunge into Saturn's atmosphere to protect its moons from potential contamination.
According to the NASA Jet Propulsion Laboratory website (refer to the link, below), the Cassini-Huygens spacecraft was launched from Florida on October 15, 1997 (EST) and reached Saturn on June 30, 2004 (PDT), which means that it took the spacecraft 6 years, 8 months, 16 days (including the arrival date).
The Cassini probe arrived in orbit around Saturn in July 2004 and, as of October 2016, continues to send information. Its mission is planned to end in September 2017 when it will enter Saturn's atmosphere.
Saturn has not been visited by any humans, only by spacecrafts and probes.The person who discovered it was Galileo.No humans have gone to Saturn, the furthest travellers have been is to the moon. We have sent a few probes to Saturn though, which have sent back detailed pictures and data.
As of October 2023, four man-made spacecraft have orbited Saturn: Pioneer 11, Voyager 1, Voyager 2, and Cassini. Cassini, which had a long and detailed mission from 2004 to 2017, provided extensive data about Saturn and its moons. The other missions contributed valuable initial observations and flybys. No other spacecraft have been specifically designed to orbit Saturn since Cassini's mission ended.
The robots that were sent to Saturn are the Voyager spacecraft, specifically Voyager 1 and Voyager 2. Launched in 1977, these spacecraft provided the first detailed images and data of Saturn and its moons during their flybys in the early 1980s. Additionally, the Cassini spacecraft, which orbited Saturn from 2004 to 2017, conducted extensive studies of the planet, its rings, and its moons.
A spacecraft visited in 2011, not 2012. There is currently one spacecraft in orbit around Mercury. NASA's MErcury Surface, Space ENvironment, GEochemistry and Ranging (MESSENGER) probe.It was launched on August 3, 2004 and entered orbit on March 18, 2011. NASA has announced that it will extend the mission longer in the harsh environments of Mercury.For more information check the MESSENGER wikipedia article.
