Moving to Brisbane

You may notice there have been few posts over the past few months, and that is because I have just finished moving to Brisbane, Queensland from Woy Woy, New South Wales.

It wasn't the longest move I ever did. (The longest was moving from America to Australia, which took four months). It wasn't the shortest, either. (We once moved another house on the same block; that move was so short, I carried my own stuff from one house to the other). However, the move was not short; almost 1,500 kilometers between houses, two days on the road, six days with essentially nothing but our sleeping bags, two and a half weeks with everything packed in boxes, and two weeks after moving with bad Internet.

This was the first move of my life I did not want to do. I had been moving on a yearly basis since I was born, and every two years I had moved to a different state or country. Instead of being sick of it, I felt quite comfortable. However, after ten houses and seven changes of postal address, at the age of thirteen feeling good not having moved in three years, I was sick of it. I didn't want to move to Brisbane.

I've changed my mind since then. Brisbane is a very nice place operated by a local government which actually does things. I live next to Mount Coot -- tha, a mountain which breaks up the city sprawl and gives astounding views of Brisbane from its summit. It's about as good as Woy Woy.

The best thing is, I think we just might stay in Brisbane. My father finally has a good job, and mother actually likes Brisbane. Whatever happens, I just don't want to move again...

Explorations of the solar system

For a long time, people have looked at the stars. Ancient civilisations, such as the Greeks and the Romans, have noticed that five objects in the sky move around. The Greeks have named these objects ἀστήρ πλανήτης(aster planetes), "wandering star". They had a name for each of the planets(Stilbon, Phosphoros, Pyroeis, Phaethon and Phainon), and gave each one a god to which it was sacred to(Hermes, Aphrodite, Ares, Cronus, and Zeus), but the Romans merely named these five after their versions of these gods(Mercury, Venus, Mars, Jupiter and Saturn). When Uranus was discovered in the 19th century, it was named after the Greek god of the sky, but Neptune was traditionally named after a Roman god, the Roman version of Poseidon.

The only planet we know that has life on it is Earth, and even though it is right under our feet, it took a long time to discover! The ancient Greeks were probably the first to find that that the world was round, more than 2000 years before Columbus. They called it Gaia.

Apollo 16. Luna 3 was the first spacecraft
 to provide a picture of it.

Earth, as we know, has only one moon, which has a volume of approximately 1/64 of the Earth's. In 1959, the first spacecraft to fly close to the moon, Luna 1, and the first spacecraft to impact the moon, Luna 2, made their missions to the rocky world. A decade later, Neil Armstrong and his crew made the first mission to bring people to the surface of the moon. Two robotic rovers went there in the 1970s.

People have also turned their attention to Mars. The first rover that landed(Sort of, it crashed) on Mars was Mars 2, launched by the USSR in the 1970s. The Viking program was the first to successfully land and operate rovers and landers on Mars. People might be sent there sometime after 2025.

Callisto, one of Jupiter's moons.

The outer planets(Jupiter, Saturn, Uranus and Neptune) have been closely photographed by the Pioneer, Voyager, Cassini and New Horizons probes. The Voyager probes have gathered information from both gas giants(Jupiter and Saturn), and are still functioning. I will not write anything else about the Voyager probes in this post, because it is about the solar system, and they have both crossed the border into interstellar space.

In the 19th century, five new planets were discovered, Vesta, Juno, Ceres, Pallas, and Pluto. They were all named after Roman gods, due to tradition, and the first four are all in between Mars and Jupiter. These bodies were all reclassified by 2006, Vesta, Juno, Ceres and Pallas as asteroids in the Asteroid belt, and Pluto as a dwarf planet.

At July 14, 2015, New Horizons took close-up pictures of Pluto for the first time, after nine years and seven months of travel. I think these will really change peoples' idea of Pluto. The pictures show that it is yellowish in colour, and displays a big heart-shaped impression on its surface.
