A-Z of space exploration.

Here is a quick information guide of space exploration.

A- astronauts. Astronauts are the people who go up to space to either explore for new information or to check that everything is working efficiently.

B- black hole. A black hole isn't necessarily to do with space exploration but it is very important in space. It is the core of a collapsed star. Its gravity is so strong that not even light can escape. Basically, a black hole could swallow up the whole of Earth.

C-Calipso satellite. The Calipso Satellite provides information for the role that clouds and atmospheric aerosols play in regulating Earth's weather, climate, and air quality. It is very important for the modern days as it will help us to solve the evergrowing problem of Climate Change.

D- Discoverer 13 . The Discoverer was launched in 1960 and it was the first recovery of a payload from Earth's orbit. It was launched by the U.S.

E- ESA. European Space Agency. European Space Agency. A group of fifteen European countries which design, develop and launch satellites and probes into space. ESA's most notable missions are Mars Express and Venus Express. The ESA works with other space agencies around the world, like NASA and the Russian Space Agency, and has Canada as a cooperating state. The nations which make up the ESA are Austria, Belgium, Denmark, Finland, France, Germany, Ireland, Italy, the Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.

F- Flyby. Mission involving a spacecraft flying past a planet, moon, comet or asteroid to take pictures and make observations of it. They were fairly common in the early years of space exploration before scientists were able to get crafts to land on objects or place them into orbits. They are also used if a spacecraft passes by an object of interest en route to another destination or is visiting multiple destinations as part of its mission (for example, Voyager 2 flew by the four Gas Giants and sent back images of all of them and some of their moons).

G- Galaxy. A large group of stars, bound together by gravity. Quite often, the galaxy will form a swirly shape. Our galaxy is the Milky Way.

H- Holidays. Richard Branson is currently in the process of developing a way to get people holidays in space

I-ISS. The ISS (or International Space Station) is where astronauts stay during their time in space. Many people stay for a long period of time while doing there research.

J- John F Kennedy. J.F.K was the president of the USA who started the Space Race. The space race was between the Soviet Union and the USA to see who could do more toward space exploration.

K- Komarov. Vladimir Komarov was the first human to die during a space mission. This is important to Space Exploration as it shows that the system is flawed.

L- Laika. Laika was the first dog to be launched into space. It was a big moment in space exploration.

M-Moon. Although the moon is obvioua, it is also extremely important to space exploration.

N-Neil Armstrong. He was the first person to step on the moon. It was a monumental moment in Space Exploration. A famous quote of his is " One small step for man, one giant leap for mankind."

O-osteopenia. This is one of the negative effects of space exploration.Venturing into the environment of space can have negative effects on the human body. Significant adverse effects of long-term weightlessness include muscle atrophy and deterioration of the skeleton.

P-Pluto. Pluto is important as a lot of exploration and research has been done into deciding whether it is a planet. It has now been declared as a Dwarf planet.

Q- Quiet. In space, it is quiet as there is a vacuum that sucks out all air and you need air to make noise.

R-Rovers. Rovers are robots that explore other planets.

S- Sputnik. This was the first satellite to be launched into space.

T-TIROS. This was the first application satellite to be launched in 1960.

U-Undiscovered. This would be a good word to describe space because there is so much of the universe that we have not seen and are very unlikely to see.

V- Vacuum. Space is a vacuum as there is no air in the atmosphere.

W- William Shepherd. He was one of the first resident crew members on board the ISS.

Y- Yuri Gagarin. He was the first person to enter space in April 1961.

Z- Zodiac. Although this does not really have an effect on the space exploration, I wanted to make sure people understood where the origin of zodiac signs come from. The Zodiac is the part of the sky that contains the constellations that are situated along the ecliptic, the path that the Sun appears to take across the sky as a year passes (in reality, it is Earth's changing position throughout the year as it orbits the Sun that causes the Sun to move through the constellations). The constellations, or signs of the Zodiac, are Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Saggitarius, Capricorn, Aquarius and Pisces. The constellation that the Sun was passing through when you were born is what determines your star sign. Astrologers believe that a person's destiny is based on their star sign and the changing positions of the objects in the night sky.
