Hidden Ocean Found Deep Inside Earth’s Mantle

Scientists report a vast water reservoir located about 700 kilometres beneath the Earth’s surface. The water is not in liquid form but is chemically bound within the mineral ringwoodite in the mantle’s transition zone. This discovery reshapes understanding of Earth’s deep water cycle and mineral storage. Ringwoodite can hold significant amounts of water under high pressure, altering theories about how Earth’s oceans may have originated and persisted.

Location: about 700 km below surface
Water storage: bound within ringwoodite in mantle
Region: transition zone of mantle
Significance: implications for Earth’s water cycle
Formation: water stored in high-pressure mineral

NASA Artemis 2 set for April 2026 launch; first crewed lunar flyby in decades

NASA's Artemis 2 mission is set for launch on 1 April 2026. The mission will send four astronauts on a 10-day journey around the Moon, marking the first crewed mission to go beyond low Earth orbit since 1972. Artemis 2 will not land on the lunar surface; instead, the crew will perform a lunar flyby and return to Earth. This flight is the first crewed test under NASA's Artemis program, designed to demonstrate long-duration deep-space operations ahead of future surface landings. The mission underscores the United States’ capability for sustained human exploration of cislunar space, and science objectives will include experiments in life support, navigation, and communications.
