NASA Spacecraft Detects Aurora and Mysterious Dust Cloud around Mars

NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft has observed two unexpected phenomena in the Martian atmosphere: an unexplained high-altitude dust cloud and aurora that reaches deep into the Martian atmosphere. The presence of the dust at orbital altitudes from about 93 miles (150 kilometers) to 190 miles (300 kilometers)…

NASA’s Hubble Observations Suggest Underground Ocean on Jupiter’s Largest Moon

NASA’s Hubble Space Telescope has the best evidence yet for an underground saltwater ocean on Ganymede, Jupiter’s largest moon. The subterranean ocean is thought to have more water than all the water on Earth’s surface. Identifying liquid water is crucial in the search for habitable worlds beyond Earth and for…

NASA’s Space Launch System Booster Passes Major Ground Test

The largest, most powerful rocket booster ever built successfully fired up Wednesday for a major-milestone ground test in preparation for future missions to help propel NASA’s Space Launch System (SLS) rocket and Orion spacecraft to deep space destinations, including an asteroid and Mars. The booster fired for two minutes, the…

Spacecraft Data Suggest Saturn Moon’s Ocean May Harbor Hydrothermal Activity

NASA’s Cassini spacecraft has provided scientists the first clear evidence that Saturn’s moon Enceladus exhibits signs of present-day hydrothermal activity which may resemble that seen in the deep oceans on Earth. The implications of such activity on a world other than our planet open up unprecedented scientific possibilities. “These findings…
