Cassini Missions Federico Martinez & Romina Bocchi
Astronautics Astronautics is the science and technology of space flight. Is the branch of aerospace engineering that deals with machines designed to work beyond the Earth's atmosphere. As with aeronautics, the restrictions of mass, temperatures, and external forces require that applications in space survive extreme conditions, that’s why it takes so long to do everySpace launch vehicles. Here we are going to talk about one of the aeronautic missions that the NASA , ESA and ASI threw to space, it's called the Cassini Equinox Mission.
About the mission Cassini–Huygens is a robotic spacecraft mission that is now studying Saturn and its natural satellites. The spacecraft consists of two elements: the Cassini orbiter (named for G.D.Cassini) and the ESA-developed Huygens probe (named for Christiaan Huygens). Cassini was the first space probe to orbit Saturn and the fourth visiting the planet. It was launched on October 1997 and it entered into orbit Saturn´s orbit on July 2004. In December 2004 the probe part was separated from the rest. Then, it reached Saturn's moon Titan on January 2005. In April 2008 the NASA announced an extension of this mission, and it was renamed Cassini Equinox Mission. In February 2010 they decided to extend it again and it will probably continue until 2017
Some biographies Giovanni Cassini Giovanni Domenico Cassini was born on 1625 in the Republic of Genova, Italy. He was a mathematician, astronomer, engineer and astrologer. As an astronomer he started being a professor in the University of Bologna, then he moved to Paris and became the director of the Paris Observatory. He was the first to observe four of Saturn´s moons. He died in Paris in 1712 at the age of 87.
Some biographies Christiaan Huygens Christiaan Huygens was born in 1629 in The Hague, Netherlands. He was a mathematician, astronomer, physicist, horologist and writer. As an astronomer he worked a lot with telescopes, Titan and Saturn´s rings and that's why this mission is called like him. He died in 1695 in Netherlands at the age of 66.
What is it good for? The Cassini-Huygens has as an objective to determinate the 3D structure and dynamic behavior of Saturn´s rings, the composition of the satellite surfaces and the history of each object. Other of its objectives are study the dynamic behavior of Saturn's atmosphere and the time variability of Titan's clouds and hazes, measure the 3D structure and dynamic behavior of the magnetosphere and determinating the nature and origin of the dark material on Iapetus's leading hemisphere
History This project started on 1982, when the European Science Foundation and the American National Academy of Sciences wanted to do something together. NASA and the ESA performed a joint study of the potential mission from 1984 to 1985, but when in 1986 ESA continued the project alone the NASA decided to do the same. After a report that said it was a NASA solo, Len Fisk from the NASA returned to the idea of doing together this project. He said that NASA would commit to the mission as soon as the ESA did. This new spirit of cooperation with Europe was driven by a sense of competition with the Soviet Union, which had begun to cooperate more with the ESA. Cassini–Huygens came under fire politically in 1992 and 1994, but NASA convinsed the U.S. Congress that it would be wrong to stop the project after the ESA had already poured funds in it because it could deteriorate their relationship in other areas. The project continued after 1994, but it wants to be stopped by some people that is affected for its contamination since 1997
Trajectory The initial gravitational-assist trajectory of Cassini is the process Whereby that is a basic study on some of its orbital momentum. The planet loses a very small proportion of its orbital momentum to the space probe. However, due to the space probe's small mass, this momentum transfer gives it a relatively large momentum increase in proportion to its initial momentum, speeding up its travel through outer space. The Cassini–Huygens space probe performed gravitational assist fly-bys at Venus, the Earth and at Jupiter.
Some discoveries - Venus and Earth fly-bys: These fly-bys provided the space probe with enough momentum to travel all the way out to the asteroid belt New moons of Saturn: Using images taken by Cassini, three new moons of Saturn were discovered in 2004. They are very small and their names are Methone, Pallene and Polydeuces.
Some discoveries Orbiting Saturn: On July 1, 2004, the spacecraft flew through the gap between the F and G rings and achieved orbit, after a seven year voyage.It is the first spacecraft to orbit Saturn. Huygens' encounter with Titan: Cassini released the Huygens probe on December 25, 2004. It entered the atmosphere of Titan on January 14, 2005, and after a two-and-a-half-hour descent landed on solid ground with no liquids in view.
