Another interesting part of news that has happened recently is NASA has
landed the Mars Curiosity rover and is now headed a quarter-mile away from its
first drill target, at a place called Glenelg Intrigue. This journey will take
weeks but will be worth it because Curiosity will be used to
investigate what brings different types of rocky material together. The rover has taken many photos of the terrain and craters. Scientists
believe they have discovered some of Mars early history and even some aspects
that make up life.
This week in class we went over the Earths internal structure, such as the mantle, crust, and core. We discussed what the core, mantle, and crust was also made of and how they help our planets gravity. We also went over the age of planet Earth and other planets as well. I learned the Big Bang theory of how chemical elements created systems prior to our own. I also learned that dust creates planets, particularly our own planet.
