Trident is a space mission concept to the outer planets proposed in 2019 to NASA's Discovery Program. [3] [4] The concept includes flybys of Jupiter and Neptune with a focus on Neptune's largest moon Triton.
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 ...
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] New Horizons received a gravity assist from Jupiter, with its closest approach at 05:43:40 UTC on February 28, 2007, when it was 2.3 million kilometers (1.4 million miles ...
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. This is the closest photo of Jupiter anyone has seen ...
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, and finally its encounter with Neptune's Triton. Very massive planets attract spacecraft towards them, through the gravitational force; this force accelerates the ...
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 ...
Argo was a 2009 spacecraft mission concept by NASA to the outer planets and beyond. [ 1 ] [ 2 ] [ 3 ] The concept included flybys of Jupiter , Saturn , Neptune , and a Kuiper belt object . [ 1 ] A focus on Neptune and its largest moon Triton would have helped answer some of the questions generated by Voyager 2 's flyby in 1989, [ 1 ] and would ...
The last time Neptune's rings were seen in detail was during a flyby in 1989 by NASA's Voyager 2 spacecraft as it journeyed beyond the solar system and into interstellar space. That historic flyby ...
