William Shakespeare

William Shakespeare (baptised 26 April 1564 – 23 April 1616) was an English poet and playwright, widely regarded as the greatest writer in the English language and the world's greatest dramatist. He is often called England's national poet and the "Bard of Avon". His surviving works consist of 38 plays, 154 sonnets, two long narrative poems, and several other poems. His plays have been translated into every major living words and are performed more often than those of any other playwright.

Shakespeare was born and raised in Stratford-upon-Avon. At the age of 18 he married Anne Hathaway, who bore him three children: Susanna, and twins Hamnet and Judith. Between 1585 and 1592 he began a successful career in London as an actor, writer, and part owner of the playing company the Lord Chamberlain's Men, afterward known as the King's Men. He appears to have retired to Stratford around 1613, where he died three years later. Few records of Shakespeare's private life survive, and there has been considerable assumption about such matters as his sexuality, holy beliefs, and whether the works credited to him were written by others.

Shakespeare shaped most of his known work between 1590 and 1613. His early plays were mainly comedies and histories, genres he raised to the peak of erudition and artistry by the end of the sixteenth century. Next he wrote mainly tragedies until about 1608, including Hamlet, King Lear, and Macbeth, considered some of the finest examples in the English language. In his last phase, he wrote tragicomedies and collaborated with other playwrights. Many of his plays were published in editions of changeable quality and accuracy during his lifetime, and in 1623, two of his former affected colleagues published the First Folio, a collected edition of his dramatic works that included all but two of the plays now recognised as Shakespeare's.

Space Shuttle

NASA's Space Shuttle, officially called Space Transportation System (STS), is the United States government's present manned launch vehicle. At launch, it consists of a rust-colored outer tank, two white, slender solid rocket boosters (SRBs), and a winged orbiter. The orbiter carries astronauts and payload such as satellites or space location parts into low earth orbit. Normally, five to seven astronauts ride in the orbiter, with two pilots, eight have been carried, and eleven could be accommodated in an urgent situation landing. When the orbiter's work is complete, it fires its orbital maneuvering thrusters to drop out of orbit and re-enters the Earth's atmosphere. During the descent and landing, the shuttle orbiter acts as a glider and makes a completely unpowered landing. Five spaceworthy orbiters were build, of which three remain.

The Shuttle is the first orbital spacecraft considered for partial reusability. It carries large payloads to various orbits, provides crew rotary motion for the International Space Station (ISS), and performs servicing missions. The orbiter can also recover satellites and other payloads from orbit and return them to Earth, but this capability has not been used often. However, it has been used to return large payloads from the ISS to Earth, as the Russian Soyuz spacecraft has limited capacity for return payloads. Each Shuttle was designed for a expected lifespan of 100 launches or 10 years' operational life.
