The Moon Changes: It’s Getting Smaller, Cooler, And Has Moonquakes, NASA Says

He said the money is required to finish development of the agency's SLS rocket, fund a new lunar lander to get astronaut to the surface and design new space suits for moon-walkers.

Over the past several hundred million years, it was found by NASA scientists that the moon reduced its size by 50 meters due to a cooling interior and it's still tectonically active.

A team of American researchers designed an algorithm to analyze seismic data recorded by NASA's Apollo missions in 1960s and 1970s which provided epicenter locations of 28 quakes on the Moon from 1969 to 1977. The American space agency has named it Artemis, after the Greek Moon goddess who was also the twin sister of the Apollo. Researchers believe that these quakes would have measured between 2 and 5 in the "Moment Magnitude scale" if they had been on earth. In March, Vice President Pence gave a speech at the National Space Council and said the return to the Moon would happen with or without NASA and called on it to become more efficient or risk being replaced. Tectonic activity makes moonquakes a regular occurrence, according to a paper in Nature Geoscience.

By tracing the moonquakes both in time and location to places where the Moon's surface is most likely to be in motion, scientists are more certain than ever that the Moon is not dead yet, and is in fact still settling its own surface, and its interactions with its closest neighbor - our own Earth. As a result, it has acquired thousands of small surface wrinkles in the form of surface features called thrust fault scarps. Astronauts maneuvered their lunar rover up and over the fault scarp. Unlike our planet, the Moon doesn't have tectonic plates; instead, its tectonic activity occurs as it slowly loses heat from when it was formed 4.5 billion years ago. Just five years from now, NASA will send one woman and one man back to the moon, landing on the lunar body's south pole.

NASA's Lunar Reconnaissance Orbiter spacecraft took this photo of the Taurus-Littrow valley, which was explored in 1972 by the Apollo 17 mission.

The instruments were placed on the lunar surface during the Apollo 11, 12, 14, 15, and 16 missions.

Nasa's next mission to the Moon will be called Artemis, the United States space agency announced Monday, though it's still looking for the money to make the journey happen by its accelerated 2024 deadline. Unlike the flexible skin on a grape, however, the lunar crust is brittle, causing it to break as the interior shrinks.

"Under my Administration, we are restoring @NASA to greatness and we are going back to the Moon, then Mars", he wrote. LRO is managed by NASA Goddard for the Science Mission Directorate at NASA headquarters in Washington.
