Primary sources It is information that is shown for the first time or original materials on which other research is based.
Secondary sources These sources offer an analysis or restatement of primary sources. They often try to describe or explain primary sources.
Tertiary sources These are sources that index, abstract, organize, compile, or digest other sources. Some reference materials and textbooks are considered tertiary sources when their chief purpose is to list, summarize or simply repackage ideas or other information.
2.The Perseverance rover is designed to study the rock record to reveal more about the geologic processes that created and modified the Martian crust and surface through time. Each layer of rock on the Martian surface contains a record of the environment in which it was formed.
3.Also aboard Perseverance is a weather station called MEDA, as well as MOXIE, a car battery-size device that will extract carbon dioxide from Mars' atmosphere and produce oxygen, just like a tree on Earth.
4.The spacecraft's self-guided descent and landing during a complex series of maneuvers that NASA dubbed "the seven minutes of terror" stands as the most elaborate and challenging feat in the annals of robotic spaceflight.
