New Moon: LRO Discovers Evidence of Young Lunar Volcanism

A series of surface features called irregular mare patches that have been recently discovered on the Moon, are thought to be remnants of small basaltic eruptions that are indicative of lunar volcanic activity as recent as several million years ago. This image by the Lunar Reconnaissance Orbiter shows one such feature, called Maskelyne. Image […]

NASA Releases First Interactive Mosaic of Lunar North Pole

A new interactive mosaic from NASA’s Lunar Reconnaissance Orbiter covers the north pole of the moon from 60 to 90 degrees north latitude at a resolution of 6-1/2 feet (2 meters) per pixel.

Next month, the Centennial, Colo.-based United Launch Alliance (ULA) will hit a milestone by launching its 75th mission since the company was formed in December 2006. Already deep into processing, the Atlas V vehicle for the scheduled late September mission will deliver the U.S. Air Force’s third Advanced Extremely […]

The Moon and Sun

Two or three times a year, NASA’s Solar Dynamics Observatory observes the Moon traveling across the Sun, blocking its view. While this obscures solar observations for a short while, it offers the chance for an interesting view of the shadow of the Moon. The Moon’s crisp horizon can be seen up […]

The Lunar Atmosphere and Dust Environment Explorer (LADEE) is due for launch in September 2013 from the Mid-Atlantic Regional Spaceport. LADEE will study the composition and structure of the tenuous lunar atmosphere, including dust that may be lofted up from […]

LRO Finds GRAIL's Lunar Impact Sites

In this image, both of the impact sites of the mirror-image GRAIL spacecraft can be seen. The final resting spots of these two spacecraft were imaged by the Lunar Reconnaissance Orbiter. Image Credit: NASA/GSFC/Arizona State University

NASA’s Lunar Reconnaissance Orbiter (LRO) has found the impacts made by its cousin(s), the Gravity Recovery and Interior […]
