Tuesday, February 28, 2017: Ten years ago today, NASA's New Horizons spacecraft flew by Jupiter and captured this photo of the gas giant with its volcanic moon, Io. Jupiter's strong gravity gave the spacecraft a 9,000-mile per hour (14,484 km/h) speed boost en route to Pluto, cutting the spacecraft's total travel time by three years. — Hanneke Weitering
