What followed was not at all what was expected, as problems turned much of the promise into gloom. What followed, however, was a variety of procedures that led to the mission recovery and returned promise to the program. Here, the authors explain how Galileo satellites 5 and 6, which were almost considered lost, put under test the ingenuity of the many engineers involved in the recovery of this mission demonstrating the technical excellence and collaborations with experts from various institutions, space agencies and industrial partners. Due to a malfunction of Soyuz Fregat upper stage, the satellites were injected into a lower and elliptical orbit instead of the planned circular orbit and with only one out of the two solar array wings deployed on both spacecraft. As a result, the satellites were left in non-nominal orbit leading to exposure to the Van Allen radiation belts, non-nominal operation of the Earth Sensors and insufficient fuel to correct the orbits entirely. The prospects for the mission were gloom to say the least, however very quickly, experts across European institutions, space agencies and industrial partners joined forces to recover the satellites and to investigate possible operational scenarios. What followed was the history of one of the most remarkable successes in the recovery of a failed launch.

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.

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. The size of this field is different in each navigation message.

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. After studying music in Venice he carried out experiments on strings to support his musical theories.

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.

He consulted with them and their advice helped him to come to his final conclusion regarding his insight. For their critical reading and sharp, stimulating suggestions, I would like to thank Michele Camerota, Paolo Galluzzi, Marco Guardo, Massimo Peri and a very careful unknown reviewer. Indeed, this is what Galileo is credited to have done. In fact, Galileo drew the best from the books of Euclid, Archimedes and other ancient mathematicians, 4 whose greatness he could fully appreciate.

In other words, he pushed himself to engineer new experiments that mimicked and explained what he could directly observe in the surrounding world before applying mathematics to their interpretation. Moreover, his statement above also clarifies the fact that he felt a definite separation existed between the simple observation of natural events through sight and the understanding thereof conceived in and by the brain.

Valuable results could only be achieved when scientific observation and technological experience were directly combined. There, he met some of the best mathematicians, natural scientists and technologists of late Italian Renaissance and became confident in considering nature as just one of the two means chosen by God to display his immense power.

Galileo Galilei (1564-1642)

British Broadcasting Corporation Home. Galileo Galilei was born on 15 February near Pisa, the son of a musician. He began to study medicine at the University of Pisa but changed to philosophy and mathematics. In , he became professor of mathematics at Pisa.

Galileo di Vincenzo Bonaiuti de’ Galilei was an Italian astronomer, physicist and engineer, Galileo studied speed and velocity, gravity and free fall, the principle of relativity, inertia, projectile motion and The earliest known written account of the legend dates to a century after his death, but Stillman Drake writes “there is.

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.

Theatre: Galileo on speed

We know that inappropriate speed kills. Conversely, lower speeds contribute significantly to greater road safety and a reduction in road deaths. Governments, through policy, public awareness and effective enforcement, have played a role in increasing road safety and reducing average road speeds. Yet, even in the face of such high-profile campaigns, drivers remain reluctant to change behaviour.

From a set of almost 1, Group/Listed race winners tested to date, less than one percent of C:C horses in Europe have demonstrated their optimum trip at a mile.

Yet, at the time he published the Dialogue , he lacked, or at least did not have in usable form, a terrestrial mechanics that could integrate these data within a systematic structure. Earlier his experimental genius and his skill at developing measuring techniques had stood him in good stead when he had considered not the motions of the heavens but those of bodies close at hand. As his manuscript fragments now show, in the period before his discoveries with the telescope he had remarkable success laying foundations for a new science of local motion based on experiment.

That probably explains why, after the humiliating defeat he had suffered at the hands of Urban VIII, he returned to his earlier interests and resumed work on the manuscript that was to become the Two New Sciences.

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.
