NASA On Air: NASA’s Curiosity Sees Blue Sunset On Mars (5/21/2015)
LEAD: NASA’s Curiosity rover captured its first Mars sunset in color and indicates the sky is blue.
1. This Martian sunset sequence was captured over seven minutes on April 15, 2015.
2. Why is it blue?
3. On Earth our sunsets are red because the molecules in the atmosphere scatter or filter out the blue wavelength light.
4. On Mars the Martian dust particles permit blue light to penetrate the atmosphere more efficiently than light that is red in color.
TAG: Dust in the Martian atmosphere is common during its spring season.
