The moon’s gravitational pull is also the force behind ocean tides and partly why our planet has a 24-hour day. Geologist and astronaut Harrison Schmitt used an adjustable sampling scoop to retrieve lunar samples during the Apollo 17 mission in 1972. Zircon crystals formed as the moon cooled 4.46 billion years ago, and a new analysis traced them in the Apollo 17 samples. NASAAn ancient landscape has been discovered beneath the East Antarctic ice sheet, thanks to ice-penetrating radar. Understanding the hidden, well-preserved landscape could help scientists predict the evolution of the ice sheet and how it may fare as temperatures warm in the climate crisis.

A half century later, crystals of the mineral zircon inside a coarse-grained igneous rock fragment collected by Schmitt are giving scientists a deeper understanding about the moon's formation and the precise age of Earth's celestial partner. This blasted magma - molten rock - into space, forming a debris disk that orbited Earth and coalesced into the moon. "I love the fact that this study was done on a sample that was collected and brought to Earth 51 years ago. "Interestingly, all the oldest minerals found on Earth, Mars and the moon are zircon crystals. The new study used atom probe tomography to determine there were no complications involving the lead atoms, confirming the age of the crystals.

CNN —Lunar dust collected by Apollo 17 astronauts in the 1970s has revealed that the moon is 40 million years older than previously believed. After landing on the moon on December 11, 1972, NASA astronauts Eugene Cernan and Harrison Schmitt collected rocks and dust from the lunar surface. A new analysis of that sample detected zircon crystals and dated them to 4.46 billion years old. “When the surface was molten like that, zircon crystals couldn’t form and survive. A lunar zircon grain is shown under a microscope.

The 50th anniversary of the last Apollo astronaut moonwalk is Wednesday. NASA astronauts say it's taking so long to return to the moon because of politics and money. But NASA built Orion to send astronauts back into lunar orbit and, as early as 2025, link up with SpaceX's Starship to land astronauts on the moon.

CNN —December’s full moon, also known as the “cold moon,” will shine bright in the night sky this Wednesday, peaking at 11:08 p.m. December 7 also marks the 50th anniversary of NASA’s Apollo 17 mission launch — the last time humans set foot on the moon. Moon observingThe full moon will make its way across the sky starting at sunset. It was the final mission of NASA’s Apollo program and brought the number of humans who have walked on the moon to a grand total of 12. Apollo 17 was the final lunar landing mission in NASA's Apollo program.

NASA is about to launch its new Space Launch System toward the moon for the first time. The rocket is designed to return astronauts to the lunar surface for the first time in more than 50 years. NASA astronauts say it's taking so long to return to the moon because of politics and money. It's not just that the Space Launch System is giant, standing taller than the Statue of Liberty. NASA/Kim ShiflettAs early as 2004, former President George Bush was setting goals to return astronauts to the moon.
