For decades, scientists have pondered the mystery of the moon’s ancient magnetism. Based on analyses of lunar samples, its now-deceased magnetic field may have been active for more than 1.5 […]
To prepare for exploring the Moon during NASA’s Artemis campaign, the agency is conducting a week-long field test in the lunar-like landscape of San Francisco Volcanic Field near Flagstaff, Arizona […]
Astronauts Charles Conrad Jr. and Alan L. Bean train for their upcoming Apollo 12 lunar landing mission. Here they are entering a simulated lunar surface area near Flagstaff, Arizona.
NASA engineers, managers, and flight directors recently traded their cubicles and conference rooms for an ancient volcanic field in the northern Arizona desert to participate in a field geology course […]
Geoconservation is an increasingly widely adopted theoretical, practical and administrative approach to the protection of geological and geomorphological features of special scientific, functional, historic, cultural, aesthetic, or ecological value.
Hadean zircons provide a potential record of Earth’s earliest subduction 4.3 billion years ago. It remains enigmatic how subduction could be initiated so soon after the presumably Moon-forming giant impact […]
Editor’s note: Our world is more or less a double planet. Our large Moon creates significant tidal forces that drive much of the way that our oceans circulate and mix. […]
One of the unique aspects of Earth is that it has a fractionally large Moon, which is thought to have formed from a Moon-forming disk generated by a giant impact.
Planets are expected to conclude their growth through a series of giant impacts: energetic, global events that significantly alter planetary composition and evolution.
Zircons are found in extraterrestrial rocks from the Moon, Mars, and some differentiated meteorite parent-bodies. These zircons are rare, often of small size, and have been affected by neutron capture […]
