The spacecraft received a boost in speed of more than 3.9 km/s (8,700 mph), and it was set on a course to Jupiter. [ 34 ] [ 35 ] [ 36 ] The flyby was also used as a rehearsal for the Juno science team to test some instruments and practice certain procedures before the arrival at Jupiter.
It parachuted through 150 km (93 mi) of the atmosphere at a speed of about 2,575 km/h (1,600 mph) [66] and collected data for 57.6 minutes until the spacecraft was destroyed. [180] The Galileo orbiter itself experienced a more rapid version of the same fate when it was deliberately steered into the planet on September 21, 2003.
Jupiter's Great Red Spot rotates counterclockwise, with a period of about 4.5 Earth days, [24] or 11 Jovian days, as of 2008. Measuring 16,350 km (10,160 mi) in width as of 3 April 2017, the Great Red Spot is 1.3 times the diameter of Earth. [21] The cloud-tops of this storm are about 8 km (5 mi) above the surrounding cloud-tops. [25]
The flyby of Earth reduced Juice’s speed by 10,737 miles per hour (4.8 kilometers per second) to set it on the path toward Venus and will save the mission around 220 to 330 pounds (100 to 150 ...
Speed limit sign in the Republic of Ireland, using "km/h.". The SI representations, classified as symbols, are "km/h", "km h −1" and "km·h −1".Several other abbreviations of "kilometres per hour" have been used since the term was introduced and many are still in use today; for example, dictionaries list "kph", [3] [4] [5] "kmph" and "km/hr" [6] as English abbreviations.
During its Jupiter encounter, the probe made measurements of the planet's magnetosphere. [33] Since the probe had no cameras, no images were taken. In February 2004, the probe arrived again at the vicinity of Jupiter. This time the distance from the planet was much greater—about 120 million km (0.8 AU)—but it made further observations of ...
Jupiter’s striking Great Red Spot has puzzled astronomers for years. Now, they think they know just how old it is and how the cyclone formed in Jupiter’s atmosphere.
