March 9th in stamps Amerigo Vespucci, Space Shuttle Discovery final landing after 39 flights

Here are some events that happened on March 9th. It could be an event or a person that died or was born on that day

1454 Born: Amerigo Vespucci, Italian cartographer and explorer (d. 1512)

Amerigo Vespucci (March 9, 1454 – February 22, 1512) was an Italian explorer, financier, navigator, and cartographer from the Republic of Florence. Sailing for Portugal around 1501–1502, Vespucci demonstrated that Brazil and the West Indies were not Asia's eastern outskirts (as initially conjectured from Columbus' voyages) but a separate continent described as the "New World". In 1507, the new continent was named America after the Latin version of Vespucci's first name.  Vespucci then became a citizen of the Crown of Castile and died in Seville (1512).

1851 Died: Hans Christian Ørsted, Danish physicist and chemist (b. 1777)

Hans Christian Ørsted (often rendered Oersted in English; 14 August 1777 – 9 March 1851) was a Danish physicist and chemist who discovered that electric currents create magnetic fields, which was the first connection found between electricity and magnetism. Oersted's law and the oersted (Oe) are named after him.

On 21 April 1820, Ørsted published his discovery that a compass needle was deflected from magnetic north by a nearby electric current, confirming a direct relationship between electricity and magnetism. The often reported story that Ørsted made this discovery incidentally during a lecture is a myth. He had, in fact, been looking for a connection between electricity and magnetism since 1818, but was quite confused by the results he was obtaining. 

His initial interpretation was that magnetic effects radiate from all sides of a wire carrying an electric current, as do light and heat. Three months later, he began more intensive investigations and soon thereafter published his findings, showing that an electric current produces a circular magnetic field as it flows through a wire.  For his discovery, the Royal Society of London awarded Ørsted the Copley Medal in 1820 and the French Academy granted him 3,000 francs.

Ørsted's findings stirred much research into electrodynamics throughout the scientific community, influencing French physicist André-Marie Ampère's developments of a single mathematical formula to represent the magnetic forces between current-carrying conductors. Ørsted's work also represented a major step toward a unified concept of energy.

A leader of the Danish Golden Age, Ørsted was a close friend of Hans Christian Andersen and the brother of politician and jurist Anders Sandøe Ørsted, who served as Prime Minister of Denmark from 1853 to 1854.

2011 – Space Shuttle Discovery makes its final landing after 39 flights.

Space Shuttle Discovery (Orbiter Vehicle Designation: OV-103) is one of the orbiters from NASA's Space Shuttle program and the third of five fully operational orbiters to be built. Its first mission, STS-41-D, flew from August 30 to September 5, 1984. Over 27 years of service it launched and landed 39 times, gathering more spaceflights than any other spacecraft to date. Like other shuttles, the shuttle has three main components: the Space Shuttle orbiter, a central fuel tank, and two rocket boosters. Nearly 25,000 heat resistant tiles cover the orbiter to protect it from high temperatures on re-entry.

Discovery became the third operational orbiter to enter service, preceded by Columbia and Challenger. It embarked on its last mission, STS-133, on February 24, 2011 and touched down for the final time at Kennedy Space Center on March 9

The mission launched at 4:53 pm EST on February 24, was carrying the Permanent Multipurpose Module (PMM) Leonardo, the ELC-4 and Robonaut 2 to the ISS. Final flight of Discovery.

Discovery was decommissioned on March 9, 2011.
