Can you be-leaf it’s fall? We sure can — especially with help from NASA’s PACE satellite! 🍂 As temperatures drop and the days get shorter in the fall, many plants stop making as much chlorophyll, a green pigment used for photosynthesis. This shift reveals more of the yellow and orange pigments in plants, causing the leaves to change color. The PACE satellite has a hyperspectral sensor that can detect subtle shifts in leaf color that our eyes can’t see. With PACE data, scientists can track chang

The sensation of free fall varies greatly between Earth, Mars, and the Moon because of their differing gravitational forces. On Earth, gravity accelerates objects downward at approximately 9.8 meters per second squared, creating a strong pulling sensation that we perceive as weight during a fall. On Mars, where gravity is only about 38% of Earth's, the acceleration in free fall drops to roughly 3.7 meters per second squared. This weaker force would make you feel significantly lighter, and your d

Fall is here (at least in the Northern Hemisphere) 🍂 Today is the autumnal equinox, where both day and night are almost exactly 12 hours long (with a few exceptions). Meanwhile, the Southern Hemisphere is welcoming the start of spring. Learn more: go.nasa.gov/3KgwAgT | NASA Jet Propulsion Laboratory
