The spacecraft Cassini–Huygens, launched in 1997, contains two identical flight recorders, each of which contains 2.5 gigabits of memory in the form of arrays of commercial DRAM chips.
Near Huygens, especially just to the east are a number of narrow ridges which appear to be the remnants of dikes, like the ones around Shiprock, New Mexico.
This same RTG power technology has been used in spacecraft such as Voyager 1 and 2, Cassini–Huygens and New Horizons, and in other devices, such as the Mars Science Laboratory,
The fundamental principle seems to be documented even before Huygens by the Jesuit philosopher, Christopher Scheiner, in Austria.

GPHSs of this, or very similar, design were used in the GPHS-RTGs of Cassini-Huygens, New Horizons, the Galileo probe, and the Ulysses probe.
By 1715-1720, he wrote his "Traité d'astronomie physique" using the Cartesian method, commenting on the nature of gravity and the movement of planets and drawing on sources such as Jean-Baptiste du Hamel and Huygens.
Besides the Huygens mission, he is also working with the Rosetta comet probe and its Plasma Consortium Experiment, and the Venus Express space probe.
He also participated in analysis of Cassini data being returned from Saturn’s magnetosphere, taught graduate-level courses as an adjoint professor of U.T. San Antonio, and led the science operations center for the TWINS mission.
On 15 October 1997, Cassini-Huygens was successfully launched from Cape Canaveral.
Previous searches for gravitational waves in space were conducted for short periods by planetary missions that had other primary science objectives (such as Cassini–Huygens), using microwave Doppler tracking to monitor fluctuations in the Earth-spacecraft distance.
It can be shown (see Fourier optics, Huygens-Fresnel principle, Fraunhofer diffraction) that the field radiated by a planar object (or, by reciprocity, the field converging onto a planar image) is related to its corresponding source (or image) plane distribution via a Fourier transform (FT) relation.
It proposes some new missions, such as a cometary mission, an extended Cassini mission (including three probes; one for the study of the atmosphere of Saturn, one atmospheric Titan probe and one to land on Titan) and a Mars sample return mission.
Spacecraft can be used to observe the solar eclipses on Jupiter, these include Pioneer 10 and Pioneer 11 (1973 and 1974), Voyager 1 and Voyager 2 (1979), Galileo orbiter (1995-2003), Cassini-Huygens (2000) and New Horizons (2007) observed the transits of their moons and its shadows.
In 1989 the Voyager 2 spacecraft observed cryovolcanoes (ice volcanoes) on Triton, a moon of Neptune, and in 2005 the Cassini–Huygens probe photographed fountains of frozen particles erupting from Enceladus, a moon of Saturn.
