The Dawn spacecraft just recently entered its lowest and final orbit around the dwarf planet Ceres, providing the closest look ever at the puzzling world. Dawn will, of course, be taking thousands more high-resolution photographs, but what else will it be doing during the remainder […]

New Horizons Conducts Final Course Correction for New Year's Day Flyby of Next KBO in 2019

Near-Earth asteroids, also known as Near Earth Objects (NEOs), are some of the best studied space rocks in the Solar System, primarily due to the fact that […]

'We're Working It, Folks': New Horizons Experiences Communications Loss, Ten Days Out From Pluto

After a 9.5-year voyage across the Solar System, New Horizons is just days away from humanity’s first close-up reconnaissance of the last of the traditionally accepted nine planets. Image Credit: NASA

Less than 10 days and a mere 7.2 million miles (11.6 million km) from its quarry—the dwarf world Pluto, its binary companion Charon, and […]

Atomic Clock project Will Bring Better Navigation, More Data for Exploration Missions
