Artist's depiction of Pioneer 10, the first spacecraft to visit Jupiter. The exploration of Jupiter has been conducted via close observations by automated spacecraft.It began with the arrival of Pioneer 10 into the Jovian system in 1973, and, as of 2024, has continued with eight further spacecraft missions in the vicinity of Jupiter and two more en route.
The spacecraft was designed to orbit Jupiter 37 times over the course of its mission. This was originally planned to take 20 months. [4] [5] Juno 's trajectory used a gravity assist speed boost from Earth, accomplished by an Earth flyby in October 2013, two years after its launch on August 5, 2011. [21]
From the planetary frame of reference, the ship's speed will appear to be limited by the speed of light — it can approach the speed of light, but never reach it. If a ship is using 1 g constant acceleration, it will appear to get near the speed of light in about a year, and have traveled about half a light year in distance. For the middle of ...
To get to Jupiter, the Clipper will first fly past Mars on March 1, using the red planet's gravity to boost its speed and bend the trajectory to send the probe back toward Earth for another ...
Jupiter is the fifth planet from ... Rupert Wildt identified absorption bands of ammonia and methane in the spectra of Jupiter. [163] Three long-lived anticyclonic ...
New Horizons used LORRI to take its first photographs of Jupiter on September 4, 2006, from a distance of 291 million kilometers (181 million miles). [105] More detailed exploration of the system began in January 2007 with an infrared image of the moon Callisto , as well as several black-and-white images of Jupiter itself. [ 106 ]
Catch Jupiter and Mars close together while you can These cosmic pairings don't happen very often, so catch a glimpse while you can. Since the year 2000, Jupiter and Mars have been in conjunction ...
The bow shock of Jupiter's magnetosphere was reached on November 16, as indicated by a drop in the velocity of the solar wind from 451 km/s (280 mi/s) to 225 km/s (140 mi/s). The magnetopause was passed through a day later. The spacecraft instruments confirmed that the magnetic field of Jupiter was inverted compared to that of Earth.
