How can you make a bigger crater on a comet? NASA needs to figure this out for the Deep Impact Project. They'll need to know the four steps in crater formation. NASA also needs to know about the tree types of craters. Also, what are comets made of? You need to know about comets and craters to solve this problem.
NASA needs to know the four steps in crater formation. The excavation step is the first step. The impactor hit and ejecta goes out into the air. The modification and continuation steps are the second and third. The walls collapse and ejecta settles. The final structure step is the last step. The central uplift of the crater stabilizes. Those are the four steps of crater formation.
The three kinds of crater is also important for NASA. The first crater is the simple crater. They are six feet wide to every one foot deep and they are less than fifteen kilometers. The complex crater is the next one. They are ten to twenty feet wide for every one foot deep and they are greater than fifteen kilometers. Lastly, we get to the impact basin. This one is more than three hundred kilometers. The impact basin also makes secondary craters. They need to know about these kinds of craters.
Lastly, NASA needs to know tons about comets. The composition of them can affect the size of the crater. They are made of dusts, gases, and ices. The parts are also important. The parts of a comet are the nucleus, coma, and the tails. Finally, the elliptical orbits of comets. They originate from beyond Pluto and get close to the sun. All of these things can affect the size of a crater.
NASA must learn about craters and comets before planning the deep impact project. The four steps in crater formation so they know the steps and how to make a bigger crater. The three types of craters, to know which one to try to make. Lastly comets, to know the composure of them. Making a crater on a comet could be lots of fun and teach us what's inside a comet.
