How do NASA scientists use geometry and measurement to predict the behavior of dangerous solar storms?
On Earth we experience extreme storms and other weather events. We have hurricanes, earthquakes, tornadoes and even tsunamis. Did you know the sun experiences storms so extreme that they can affect us on Earth, 150,000,000 kilometers (93 million miles) from the sun?
In these problems, students analyze images of a solar tsunami and use geometry and measurement skills to find the speed of the wave. They step into the shoes of a NASA scientist and use geometry to find the speed of a coronal mass ejection, or CME, also known as a solar storm. CMEs can have hazardous effects on the International Space Station and astronauts.
