Question:
Terence Joseph "Terry" Nation (8 August 1930 - 9 March 1997) was a Welsh television writer and novelist. Nation first made his name as a comedy writer before becoming a prolific writer for drama, working on many of the most popular British series of the 1960s and 1970s. He made a significant contribution to the long-running BBC science-fiction series Doctor Who from its outset, creating the villainous Daleks which established its early popularity and later devising the recurring character of Davros.
Having returned to writing for Doctor Who, the BBC commissioned Nation to create a new science-fiction drama series. First broadcast in 1975, Survivors is the post-apocalyptic story of the last humans on Earth after the world's population has been devastated by plague. Although the series was well received, Nation's creative vision conflicted with that of producer Terence Dudley, and the final two seasons were produced without Nation's involvement. Meanwhile, screenwriter Brian Clemens claimed that he had related the concept for Survivors to Nation in the late 1960s, having registered it with the Writers' Guild of Great Britain in 1965; Nation denied the allegations. Although the case was ultimately brought before the High Court, both sides withdrew from the proceedings after their legal costs mounted. The production of Nation's next BBC creation, Blake's 7, experienced fewer problems. This series follows a group of criminals and political prisoners who are on the run from the evil "Terran Federation", piloting a stolen spaceship of unknown origin. Running for four seasons from 1978 to 1981, Blake's 7 acquired a worldwide fan following, and proved especially popular in Britain. Although Nation scripted the whole of the first season of Blake's 7, his creative influence subsequently declined in the following two seasons despite writing some key episodes, as script editor Chris Boucher exerted a greater influence on those seasons. Nation didn't write any episodes in the fourth season of Blake's 7. In the 1980s, Nation attempted, without success, to secure funding for a fifth season of Blake's 7. During the 1970s, Nation wrote a children's novel for his daughter Rebecca (after whom he named the character of Rebec in the 1973 Doctor Who serial Planet of the Daleks) titled Rebecca's World: Journey to the Forbidden Planet, as well as a novel based on Survivors.

Answer the question at the end by quoting:

Ferdinand Magellan ( or ; Portuguese: Fernao de Magalhaes, IPA: [fir'naw di maga'yajS]; Spanish: Fernando de Magallanes, IPA: [fer'nando de maga'yanes]; c. 1480 - 27 April 1521) was a Portuguese explorer who organised the Spanish expedition to the East Indies from 1519 to 1522, resulting in the first circumnavigation of the Earth, completed by Juan Sebastian Elcano. Born into a Portuguese noble family in around 1480, Magellan became a skilled sailor and naval officer and was eventually selected by King Charles I of Spain to search for a westward route to the Maluku Islands (the "Spice Islands"). Commanding a fleet of five vessels, he headed south through the Atlantic Ocean to Patagonia, passing through the Strait of Magellan into a body of water he named the "peaceful sea" (the modern Pacific Ocean).
Magellan was born in northern Portugal in around 1480, either at Vila Nova de Gaia, near Porto, in Douro Litoral Province, or at Sabrosa, near Vila Real, in Tras-os-Montes e Alto Douro Province. He was the son of Rodrigo de Magalhaes, Alcaide-Mor of Aveiro (1433-1500, son of Pedro Afonso de Magalhaes and wife Quinta de Sousa) and wife Alda de Mesquita and brother of Leonor or Genebra de Magalhaes, wife with issue of Joao Fernandes Barbosa. In March 1505 at the age of 25, Magellan enlisted in the fleet of 22 ships sent to host D. Francisco de Almeida as the first viceroy of Portuguese India. Although his name does not appear in the chronicles, it is known that he remained there eight years, in Goa, Cochin and Quilon. He participated in several battles, including the battle of Cannanore in 1506, where he was wounded. In 1509 he fought in the battle of Diu. He later sailed under Diogo Lopes de Sequeira in the first Portuguese embassy to Malacca, with Francisco Serrao, his friend and possibly cousin. In September, after arriving at Malacca, the expedition fell victim to a conspiracy ending in retreat. Magellan had a crucial role, warning Sequeira and saving Francisco Serrao, who had landed. In 1511, under the new governor Afonso de Albuquerque, Magellan and Serrao participated in the conquest of Malacca. After the conquest their ways parted: Magellan was promoted, with a rich plunder and, in the company of a Malay he had indentured and baptized Enrique of Malacca, he returned to Portugal in 1512. Serrao departed in the first expedition sent to find the "Spice Islands" in the Moluccas, where he remained. He married a woman from Amboina and became a military advisor to the Sultan of Ternate, Bayan Sirrullah. His letters to Magellan would prove decisive, giving information about the spice-producing territories. After taking a leave without permission, Magellan fell out of favour. Serving in Morocco, he was wounded, resulting in a permanent limp. He was accused of trading illegally with the Moors. The accusations were proved false, but he received no further offers of employment after 15 May 1514. Later on in 1515, he got an employment offer as a crew member on a Portuguese ship, but rejected this. In 1517 after a quarrel with King Manuel I, who denied his persistent demands to lead an expedition to reach the spice islands from the east (i.e., while sailing westwards, seeking to avoid the need to sail around the tip of Africa), he left for Spain. In Seville he befriended his countryman Diogo Barbosa and soon married the daughter of Diogo's second wife, Maria Caldera Beatriz Barbosa. They had two children: Rodrigo de Magalhaes and Carlos de Magalhaes, both of whom died at a young age. His wife died in Seville around 1521. Meanwhile, Magellan devoted himself to studying the most recent charts, investigating, in partnership with cosmographer Rui Faleiro, a gateway from the Atlantic to the South Pacific and the possibility of the Moluccas being Spanish according to the demarcation of the Treaty of Tordesillas.

When did Magellan first travel?
In March 1505 at the age of 25, Magellan enlisted in the fleet of 22 ships sent to host D. Francisco de Almeida as the first viceroy of Portuguese India.
