SPACE IN THE NEWS- PHILAE LANDING ON COMET
After about more than 10 years of journey, the robotic lander which is Philae landed on the surface of the comet 67P/Churyumov-Gerasimenko on November 12th 2014. Philae and the mother spacecraft, Rosetta were roughly about 500 million kilometers away from Earth. Numerous spacecraft had spent several hours interpreting, and observing comet from above. However, until Philae’s landing, no one had ever placed researching lander on to a comet. The robotic lander has been sending back various photos of the comet to the European Space Agency’s Science and Technology Center in Noordwijk, the Netherlands. While Philae is snapping many images from the comet 67P, Rosetta is also orbiting the comet, and snapping many images from above. Scientists have planned to make Rosetta stay on the tiny celestial rock, until at least December 2015. But, the scientists are not expecting for Philae to stay for more than about four months because when the comet 67P gets near the sun, the comet will heat up heavenly. At the same time, the robotic lander will essentially get fried.
Comets and asteroids are thought to be the oldest relics of the solar system. People can’t go back to the past billions of years in time to see how the solar system was made. Therefore, comets and asteroids are the best option to see how the solar system changed and how it was created. I think that this has a relationship with the Big Bang Theory. Big Bang Theory is a very famous theory that talks about how the solar system was formed in 13.7 billion years ago. Well, in the theory, it also described about that asteroids and comets are formed from the leftovers when making the planets.
From the article, it also suggested that the comet 67P’s water could be the same type that make up the Earth’s ocean. The scientists noticed that most of the comets-they have studied-has a large amount of deuterium than Earth does. If the comet 67P do have the same thing, that would argue that comets are mostly made out of Earthly water. However, some people might instead argue that asteroids were the main source of Earthly water. Scientists have found an asteroid called Ceres that contained Earthly water. This asteroid is in the asteroid belt (which is between Mars and Jupiter). Some scientists think that it is big enough to be a dwarf planet. This asteroid actually condenses water just like a comet.
Rosetta and Philae are making more observations on the mysterious celestial matter.
The science in the article will affect the world socially because it will make the other countries to learn how earths made and what does comets and asteroids consists. Astronomy laboratories from around the world will communicate with this astronomy laboratory that is researching about comets and asteroids to help there to do this discovery more quicker. Having more people together working will make the exploration process go quicker, and there will be more ideas to use.
The science in the article can be beneficial or harmful to people and the planet. The science in the article can be beneficial because in the article it explained that comets, and the asteroids are the best way for learning how the universe evolved, which means that if we use Philae and Rosetta, we can find about a lot of information, and evidences to find out how actually the universe was created! We can have more information, and evidences to prove that the Big Bang Theory is correct nor incorrect. On the other hand, it can be harmful because it costs a large amount of money to do this exploring, and robotic landers are very easy to burn when it go near the sun. Robotic landers doesn’t last for a very long time.
KEY VOCABULARIES IN THE ARTICLE:
Relic: A relic is something that is leftover from a long time ago.
Condensation: if the water, which is vapored is cooled, it changes to water. It’s the change of gas to liquid. This process is called condensation.
Coalesce: Coalesce means to force and to join together many small elements to form combined mass.
Deuterium: Deuterium is one of the isotopes(one of the possible different forms of an atom of a particular element) of hydrogen. It has one proton, one neutral and one electron.
