The shuttle was launched out of Earth's gravity and into space by 3 rocket engines on the back of the orbiter along with help from 2 long white Solid Rocket Boosters (also called SRBs) Fuel for the shuttle was stored in the large, usually orange, External Fuel Tank (also called ET). Before the shuttle reached orbit, the SRBs were released and fell into the Atlantic Ocean where they were towed back to shore for reuse. The ET was also released but broke up and fell into the Indian Ocean and was not reused.
Orbiter had a payload bay for various missions rather than deploying satellites. They were the following:
The US space shuttles were:
A '†' next to a name means that the Shuttle was destroyed.
There was a Russian Shuttle called Buran. It flew one unmanned flight before being retired. The Buran was destroyed in a hangar collapse in 2002.
The shuttle was created in 1973. It replaced the Apollo capsules. The first flight was a test of the landing and maneuvering abilities of the shuttle. This flight used Space Shuttle Enterprise. The first shuttle flight in space was on April 12, 1981. It used Space Shuttle Columbia.
On January 28, 1986 the Space Shuttle Challenger destroyed 73 seconds into the flight of STS-51-L. It caused a year long stall in space flight.
In the 1990s the Shuttle began working on the International Space Station (ISS). This was its main job of the shuttle since then.
Also in the 1990s, the Space Shuttle launched the Hubble telescope into space. Shuttle missions returned 5 times to repair and improve cameras and scientific instruments on the telescope.
On February 1, 2003, the Space Shuttle Columbia broke up while returning STS-107 to Earth over Texas. The accident was caused by damage to the heat-shield which protects it from the heat of reentry into the Earth's atmosphere. It again caused a long delay until the next shuttle flight.
In 2010, NASA shut down the Space Shuttle program. They were more expensive to use than other launch vehicles.
Currently, the United States has no manned spacecraft capabilities. Both SpaceX with the Crew Dragon and Boeing with their Starliner capsule, are planning to provide crewed missions to the ISS. NASA is developing the Orion capsule for beyond Earth orbit missions.
The remaining shuttles are now on display at the following museums:
Thor
Thor (Old Norse: "Þórr") is the god of thunder and lightning in Norse mythology, associated with strength, storms, hallowing and fertility. He is the son of Odin and Jörð, the personification of the Earth, and is the strongest of the Æsir.
Thor is described as being fierce eyed, with red hair and a full beard, and he is quick to anger and has an enormous appetite.
The champion of Asgard, Thor is said to protect both it and Midgard from the likes of the jǫtnar, a race of beings native to Jötunheimr. He is known in Old English as Þunor ("Thunor") and in Old High German as Donar (runic "þonar" ᚦᛟᚾᚨᚱ), all of which stem from the Proto-Germanic "*Þunraz," meaning "thunder".
The modern English weekday Thursday (from Old English "Þūnresdæg", “Thunor’s [Thor’s] day”) bears the god's name...
Thor is the son of Odin, chief of the Æsir, and Jörð, the living personification of the Earth. He is the eldest of Odin's sons and is the half-brother of Baldr, Höðr, Víðarr, and Váli.
He is married to the golden-haired goddess Sif, with whom he has a daughter, Þrúðr. With his jötunn lover Járnsaxa, Thor has two sons, Móði and Magni. He has a stepson, Ullr, who is Sif's son by a previous marriage.
Thor was believed to travel in a chariot drawn by two goats named Tanngrisnir and Tanngnjóstr. According to writings known as sagas, Thor wielded a short-handled war hammer, Mjolnir.
It was fashioned for him by the dwarven brothers Eitri and Brokkr, and is said to be the most powerful weapon in all the Nine Worlds, capable of crushing even mountains. When Thor threw the hammer, it magically returned to the god's hand.
Other attributes of Thor include a pair of gauntlets known as Járngreipr, which he is required to wear in order to wield Mjölnir, a belt, Megingjörð, which doubles his strength when he wears it, and a staff, Gríðarvölr, which, along with Járngreipr, was given to him by the jötunn Gríðr.
Thor is a character in Marvel Comics, his full name being Thor Odinson; son of Odin and Frigga, he is the god of thunder and a founding member of the "Avengers". His archenemy is Loki, god of trickery and mischief as well as Thor's younger adopted brother. In the Marvel Cinematic Universe, Australian actor Chris Hemsworth plays the role of Thor. Hemsworth played Thor in “Thor” (2011), “The Avengers” (2012), “Thor: The Dark World” (2013), “Avengers: Age of Ultron” (2015), “Thor: Ragnarok” (2017), “Avengers: Infinity War” (2018), and “Avengers: Endgame,” which was released in April 2019. He will return as the Odinson in “Thor: Love and Thunder” (tentative release date), and is also scheduled to be in the next 'Guardians of the Galaxy' film by Marvel, scheduled for release in 2021, but may be delayed due to covid_19 restrictions.

Blood cell
A blood cell is any cell of any type found in blood. There are three main types of blood cells in mammals:
Windsurfing
Windsurfing is a water sport invented in the U.K. by Peter Chilvers in 1958 on Hayling Island, Hampshire. It is performed on a board with a sail. The sail both empowers the board and helps the board change directions. The sport is a combination of surfing and sailing. Windsurfers can travel on either flat or rough water, as long as there is wind. Windsurfing is done mostly in the summer and spring.
Windsurfing competitions can be freestyle or racing around buoys and it features in the Olympics.
Windsurfing sails come in many different sizes. The larger the sails are, the more human strength is needed to control them, but the more power is given to go faster. The different sizes of board affect the speed. Again, the thinner the board, the faster you will go. The range of thickness depends on the materials used.
Another sport similar to windsurfing is kite surfing. All these sports have boards that range in size and price, but all need much practice to be done well. There are many sporting places around the world that people travel to just to go surfing. Some of the best places are in the west coast of the United States, Hawaii, Australia, and Indonesia.
Thoroughbred
Thoroughbred is a breed of horse. They are mainly used for racing.
Their pedigree is known and recorded. For each horse there is a chart showing its ancestry.
Horses in general have been used for many years, for farm, racing, harness work and so forth. Horses were the fastest way for people to travel on land before cars were invented. They were the only way to travel long distances in a reasonable amount of time.
Most horse breeds have been bred for a specific reason; the thoroughbred racehorse was bred to run. Thoroughbreds originate from the Arabian breed, and all thoroughbreds can be traced back to three original sires (fathers): The Byerley Turk, The Darley Arabian, and The Godolphin Arabian. Thoroughbreds are known for their speed, and also for their jumping ability, used in steeplechases and in show jumping and other horse activities. Although thoroughbreds generally are slightly temperamental, they are very trainable and loyal.
Thoroughbreds are generally tall and sleek, with long legs to help carry them along the race track. Thoroughbreds can be many colors, including bay (a colour which is brown with a black mane and tail), chestnut (red-brown), black, and gray.
