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.
Space debris: Tracking active and inactive satellites and space debris to better understand the debris environment; providing data, analysis and advice to spacecraft engineers to perform collision avoidance manoeuvres as well as developing a system of automated collision avoidance. The space debris office also works with the international ...
Galileo 's prime mission was a two-year study of the Jovian system, but on March 26, 1993, while it was en route, astronomers Carolyn S. Shoemaker, Eugene M. Shoemaker and David H. Levy discovered fragments of a comet orbiting Jupiter, the remains of a comet that had passed within Jupiter's Roche limit and had been torn apart by tidal forces.
Observation of the spacecraft communications as it passed behind Jupiter would allow measurements of the planetary atmosphere, while tracking data would improve estimates of the mass of Jupiter and its moons. [6] NASA Ames Research Center, rather than Goddard, was selected to manage the project as part of the Pioneer program. [10]
NASA's Juno spacecraft captured this view of Jupiter during the mission's 54th close flyby of the giant planet Sept. 7, 2023.
The trajectories that enabled the Voyager spacecraft to visit the outer planets and achieve velocity to escape the Solar System Plot of Voyager 2 ' s heliocentric velocity against its distance from the Sun, illustrating the use of gravity assist to accelerate the spacecraft by Jupiter, Saturn and Uranus.
[needs update] After entry into the Jupiter system, Europa Clipper will perform a flyby of Ganymede at an altitude of 500 km (310 mi), which will reduce the spacecraft velocity by ~400 m/s (890 mph). This will be followed by firing the main engine at a distance of 11 Rj (Jovian radii), to provide a further ~840 m/s (1,900 mph) of delta-V ...
