Where is the Cassini Spacecraft right now?

The app above shows the position of the Cassini Spacecraft right now - in its orbit about Saturn. You can wind the animation backwards in time to watch its launch and its flybys of Venus, the Earth, Jupiter, and insertion into orbit around Saturn. If you zoom in closer you can just about see where it is in its orbit.

This collage of images from NASA's Cassini spacecraft shows Saturn's northern hemisphere and rings as viewed with four different spectral filters. Each filter is sensitive to different wavelengths of light and reveals clouds and hazes at different altitudes.

The image was taken with the Cassini spacecraft wide-angle camera on Dec. 2, 2016, at a distance of about 400,000 miles (640,000 kilometers) from Saturn.

These images were obtained about two days before its first close pass by the outer edges of Saturn's main rings during its penultimate mission phase. Article

Cassini Getting closer for best ever views of rings and moons

Cassini is getting ready for it's finale when it will crash into Saturn. As a prelude it will start grazing the rings. Article

Cassini perform a last close flyby of Saturn’s Moon Dione on August 17th 2015.

Cassini has been orbiting Saturn since 2004. After a series of close moon flybys in late 2015, the spacecraft will depart Saturn's equatorial plane -- where moon flybys occur most frequently -- to begin a year-long setup of the mission's daring final year. For its grand finale, Cassini will repeatedly dive through the space between Saturn and its rings. Read more here.

Cassini Flight Path

Cassini-Huygens was launched on 15th October 1997. It was comprised of two spacecraft - Cassini to orbit Saturn for many years studying the planet and its moons and rings, and Huygens - an atmospheric probe which successfully landed on Saturn’s largest moon Titan.

The flight path involved 4 gravitational assists with 2 fly-pasts of Venus, one of the earth and a final flypast of Jupiter before the spacecraft eventually reached Saturn. Asteroid 2685 Masursky was also imaged (as a small dot) on the way from a distance of 1.6 million km.

Cassini Orbit Insertion

The insertion into orbit around Saturn was fraught with danger from possible collisions with dust and bigger particles orbiting Saturn. For an in-depth description of the process this article written just before orbit was achieved provides an interesting view of the complex procedures required to reach orbit safely.

Cassini initial Orbits - NASA/JPL

The first orbit of Saturn reached a maximum distance of some 9 million km from the planets centre. Subsequent engine burns reduced that distance to around half or less for most of the rest of the mission. At its closest part of each orbit Cassini generally reaches about 1 million km from the planet.

The Surface of Titan

Surface of Titan

Cassini released the probe Huygens, on the 25th December, 2004 and it entered Titan's atmosphere on the 14th January 2005. It took 2.5 hours for the lander to reach the surface and was able to transmit data for a further 90 minutes which was longer than it was design to do. Huygens remains the furthest any probe has ever landed from earth.

The images Huygens returned appeared to show a shore line with channels leading into a methane sea. After a short bounce after hitting the ground, the probe returned images showing a flat plane strewn with (possibly ice) pebbles. The temperature was -180 degrees C and the atmosphere was high in methane vapour with gentle winds at the surface (after experiencing 400km/hour winds at high altitude).

Cassini Findings

Cassini has undoubtedly found out more about Saturnian system than was ever known before. For an in-depth report (at 1 hour 16 minutes long) with some fantastic imagery, watch the following video.

Cassini Mission End

The initial mission was extended in 2008 as the Cassini Equinox Mission and was then extended again as the current Cassini Solstice Mission. This mission will end with the spacecraft deliberately entering into Saturn's atmosphere in 2017 which will destroy the spacecraft.
