This was 8 km (5 mi) higher than predicted, and the time of the closest approach was within a second of the prediction. It was the first time that a deep space probe had returned to Earth from interplanetary space. [62] A second flyby of Earth was at 304 km (189 mi) at 15:09:25 UTC on December 8, 1992. [82]
The first spacecraft to explore Jupiter was Pioneer 10, which flew past the planet in December 1973, followed by Pioneer 11 twelve months later. Pioneer 10 obtained the first close-up images of Jupiter and its Galilean moons; the spacecraft studied the planet's atmosphere, detected its magnetic field, observed its radiation belts and determined ...
First flyby of Jupiter. First spacecraft beyond the Inner Solar System. USA (NASA) Pioneer 10 [33] January 1974 First spacecraft to return data on a long-period comet. USA (NASA) Mariner 10 [34] 5 February 1974: First mission to explore two planets in a single mission (Mercury and Venus). First photograph of Venus from space.
Great conjunctions attracted considerable attention in the past as omens. During the late Middle Ages and Renaissance they were a topic broached by the pre-scientific and transitional astronomer-astrologers of the period up to the time of Tycho Brahe and Johannes Kepler, by scholastic thinkers such as Roger Bacon [3] and Pierre d'Ailly, [4] and they are mentioned in popular and literary works ...
First probe to enter Jupiter's atmosphere. Entered at 22:04 UTC on 7 December 1995 and operated for 57 minutes; main spacecraft entered orbit at 00:27 UTC on 8 December. [13] Spacecraft was deorbited on 21 September 2003, impacting Jupiter's atmosphere at 18:57:18 UTC. [14] – Ulysses: Ulysses: 6 October 1990 [2] Space Shuttle Discovery STS-41 ...
Observations of variations in the brightness of Io as it rotated, made by Joel Stebbins in the 1920s, showed that Io's day was the same length as its orbital period around Jupiter, thus proving that one side always faced Jupiter just as the Moon's near-side always faces the Earth. [27]
NASA's Juno spacecraft recently flew by Jupiter, collecting crucial data -- and the best look we've gotten at the planet in a very long time.
During the opposition period 1503 Mars stood 3 times in conjunction with Jupiter (October 5, 1503, January 19, 1504, and February 8, 1504) and 3 times in conjunction with Saturn (October 14, 1503, December 26, 1503, and March 7, 1504). Jupiter and Saturn stood on May 24, 1504, in close conjunction with an angular separation of 19 arcminutes.
