On February 13, , Italian philosopher, astronomer and mathematician Galileo Galilei arrives in Rome to face charges of heresy for advocating Copernican theory, which holds that the Earth revolves around the Sun. Galileo officially faced the Roman Inquisition in April of that same year and agreed to plead guilty in exchange for a lighter sentence. Galileo, the son of a musician, was born February 15, , in Pisa, in what is today known as Italy. He entered the University of Pisa planning to study medicine, but shifted his focus to philosophy and mathematics. In , he became a professor at Pisa for several years, during which time he demonstrated that the speed of a falling object is not proportional to its weight, as Aristotle had believed. According to some reports, Galileo conducted his research by dropping objects of different weights from the Leaning Tower of Pisa.
He constructed a telescope with which he studied lunar craters, and discovered four moons revolving around Jupiter and espoused the Copernican cause. View ten larger pictures. Vincenzo, who was born in Florence in , was a teacher of music and a fine lute player.

Like the famed astronomer for which it was named, Galileo would study the King of Planets over an extended period, in finer detail than was ever possible before. Galileo changed the way we look at our solar system. When the spacecraft plunged into Jupiter’s crushing atmosphere on Sept. The spacecraft was the first to fly past an asteroid, Gaspra, and the first to discover a moon of an asteroid, tiny Dactyl orbiting Ida.
It provided the only direct observations of a comet colliding with a planet, when it witnessed Shoemaker-Levy 9 impact Jupiter. The Galileo spacecraft logged quite a few other firsts during its year mission to Jupiter. Among its discoveries: an intense radiation belt above Jupiter’s cloud tops, helium in about the same concentration as the Sun, extensive and rapid resurfacing of the moon Io because of volcanism and a magnetic field at Ganymede.
The orbiter carried a small probe that became the first to sample the atmosphere of a gas planet. The probe measured temperature, pressure, chemical composition, cloud characteristics, sunlight and energy internal to the planet, and lightning. The Galileo mission is also an example of innovative problem solving. Despite exhaustive efforts to free the ribs, the antenna would not deploy.
From to , extensive new flight and ground software was developed, and ground stations of NASA’s Deep Space Network were enhanced in order to perform the mission using the spacecraft’s low-gain antennas. Launch : Oct. Earth flybys: Dec.
This study aims to show that the experimental confirmation of his conjectural ideas was a constant concern for Galileo from the very beginning of his scientific activity. In order to support my view, I shall quote his early experimental work and first show the extent to which he was able to analyse his results in depth by himself. Then I shall give evidence that he discussed his results with other scientists to help confirm his initial intuitive ideas.

Equinome scientists have found that horses with the C:C genotype have an optimum race distance less than or equal to 1 mile. The Equinome Speed Gene Test was launched in January following the publication by Dr Emmeline Hill, a leading equine genomics researcher in University College Dublin and Chief Scientific Officer of Plusvital, of a scientific paper which revealed the association of a gene related to muscle development with optimum racing distance in Thoroughbred racehorses.
Since then, more than twenty scientific publications, including studies by separate independent international research groups in the US, Italy and Japan, have further validated this study and investigated the effect of the gene in other horse breeds. Clients include some of the top 5 global racing and breeding organisations as well as owners and breeders with considerably smaller operations.
The most significant recent development was the merger between Plusvital and Equinome announced in December , which has led to the creation of a broader equine science company which will be headquartered in Dublin with offices worldwide.

The Galileo Signal-In-Space data channels transmit different messages type according to the general contents identified in the following table. The following table indicates the signal component associated to each navigation message type.
The complete navigation message data are transmitted on each data component as a sequence of frames. A frame is composed of several sub-frames, and each sub-frame is composed of several pages. The page is the basic structure for building the navigation message. The general structure of the navigation messages are common but the number of sub-frames and pages as well as the duration of each page are not the same, as represented in the following table.
This arrangement allows accomplishing the three different main categories of data to be transmitted at different rates:. In addition both navigation messages transmit a CRC data field in order to detect corrupted data.

Galileo’s Inclined Plane Experiment. Main Concept. Galileo Galilei is considered to be one of the fathers of modern science due to his extensive research in astronomy and physics. Galileo hypothesized that a falling object would gain equal amounts of velocity in equal amounts of time, which meant that its speed increased at a constant rate as it fell. There was one problem, however, in testing this hypothesis: Galileo could not observe the object’s free falling motion and at the time, technology was unable to record such high speeds.
As a result, Galileo tried to decelerate its motion by replacing the falling object with a ball rolling down an inclined plane. Since free falling is essentially equivalent to a completely vertical ramp, he assumed that a ball rolling down a ramp would speed up in the exact same way as a falling ball would. The Conclusion. Using a water clock, Galileo measured the time it took for the ball to roll a known distance down the inclined plane.
After many trials, he observed that the amount of time it took for the ball to roll down the entire length of the ramp was equal to double the amount of time it took for the same ball to only roll a quarter of the distance.

Galileo studied speed and velocity , gravity and free fall , the principle of relativity , inertia , projectile motion and also worked in applied science and technology, describing the properties of pendulums and ” hydrostatic balances”, inventing the thermoscope and various military compasses , and using the telescope for scientific observations of celestial objects. His contributions to observational astronomy include the telescopic confirmation of the phases of Venus , the observation of the four largest satellites of Jupiter , the observation of Saturn’s rings , and the analysis of sunspots.
Galileo’s championing of heliocentrism and Copernicanism met with opposition from within the Catholic Church and from some astronomers. The matter was investigated by the Roman Inquisition in , which concluded that heliocentrism was “foolish and absurd in philosophy, and formally heretical since it explicitly contradicts in many places the sense of Holy Scripture”.

The complete system consists of:. The first two IOV satellites were launched on Oct. It includes an initial operational capability phase of 18 operational satellites. The full system will consist of 30 satellites, control centers located in Europe and a network of sensor stations and uplink stations installed around the globe.
Political decisions made by the European Parliament and the Council in resulted in the allocation of a budget for the European satellite navigation programs EGNOS and Galileo and provided for an agreement on the governance structure of the programs. This framework provides for the deployment of the FOC Full Operational Capability of Galileo under a public procurement scheme, entirely financed out of the European Community budget.
The procurement initiated includes six WPs Work Packages. In this setup, ESA functions in its role as the designated procurement agent on behalf of the European Union: 1. On Oct.

Between and , the Italian scientist Galileo Galilei is said to have dropped two Aristotle’s theory of gravity (which states that objects fall at speed proportional to their mass). Some contemporary sources speculate about the exact date; e.g. Rachel Hilliam gives (Galileo Galilei: Father of Modern Science.
Electronic music, written by Tom Rowlands of Chemical Brothers fame, blares through the speakers as the actors dance around, pumping up the audience. A short puppet show sets the stage and we find Galileo in his house discussing with Andrea, his housekeeper’s son and trusted student, Copernicus’s heliocentric system.
