At this point, the spacecraft was 83 million kilometers (52 million miles) from Jupiter, but 664 million kilometers (413 × 10 ^ 6 mi) from Earth, and telemetry from the spacecraft, transmitted at the speed of light, took 37 minutes to reach JPL. A tiny frequency change in the radio signal indicated that the separation had been accomplished.
Jupiter might have shaped the Solar System on its grand tack. In planetary astronomy, the grand tack hypothesis proposes that Jupiter formed at a distance of 3.5 AU from the Sun, then migrated inward to 1.5 AU, before reversing course due to capturing Saturn in an orbital resonance, eventually halting near its current orbit at 5.2 AU.
Galileo did both. One section of the spacecraft rotated at 3 revolutions per minute, keeping Galileo stable and holding six instruments that gathered data from many different directions, including the fields and particles instruments. Galileo was intentionally destroyed in Jupiter's atmosphere on September 21
Galileo arrived at Jupiter on December 7, 1995, after a six-year journey from Earth during which it used gravity assists with Venus and Earth to boost its orbit out to Jupiter. Shortly before Galileo ' s Jupiter Orbit Insertion maneuver, the spacecraft performed the only targeted flyby of Io of its nominal mission.
The trip from Earth to Jupiter, the probe's exploration of the Jovian atmosphere, and an orbiter tour consisting of 11 orbits of Jupiter constituted Galileo ' s primary mission. On Jupiter Arrival Day (7 December 1995), the Galileo spacecraft was given a gravity-assist from Io and then subjected to the Jupiter orbit insertion (JOI) maneuver ...
If successful, it will put JUICE on course to reach Jupiter and its three large ocean-bearing moons - Callisto, Europa and Ganymede - in 2031 with the help of three further single gravity assists ...
The European Space Agency’s Juice mission to study Jupiter’s icy moons conducted a daring double flyby of Earth and the moon to help it reach the largest planet in our solar system.
The closest in the past 1,000 years was in 1761, when Mars and Jupiter appeared to the naked eye as a single bright object, according to Giorgini. Looking ahead, the year 2348 will be almost as close.
