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

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

The study appears in the journal Nature Geoscience.

The budget increase is on top of the initial $US21 billion ($30.19 billion) budget request from NASA to accelerate the return to the lunar surface. These are cliffs caused by the Moon's surface shearing away from itself, thanks to long-term shrinking and contracting of the surface. Apparently, the moon is aging the same way. This was close enough for the team to conclude that the faults likely caused the quakes.

The researchers found that moonquakes - first observed by Apollo astronauts over 50 years ago - tend to happen when the Moon is at or near its apogee, the point in the Moon's orbit when it is farthest from Earth.

Unlike Earth, the moon doesn't have tectonic plates. Tectonic pushing and pulling of the moon's crust also resulted in lobate scarps (curved hills) and graben (shallow trenches).

Realizing more about the enterprise involving where the moon's surface is still active could assist scientists to discern where and where not to land subsequent spacecraft.

The Moon is shrinking as it becomes cooler from the inside, according to latest research conducted by the National Aeronautical and Space Administration (NASA).

It turns out these faults keep the moon tectonically active, generating relatively strong quakes up to about a magnitude 5 on the Richter scale.

"Fifty years after Apollo, the Artemis program will carry the next man and first woman to the moon", said Bridenstine during a press call.

Watters hopes the LRO team will be able to re-analyse fault scarps imaged by the orbiter since 2009 to find evidence of movement-that would be a smoking gun signature, he said.

Additionally, one of the revised moonquake epicenters is just 13 kilometers (8 miles) from the Lee-Lincoln scarp traversed by the Apollo 17 astronauts.

The scientist took the data from the seismometers (a device that responds to ground motions, such as caused by earthquakes, volcanic eruptions, and explosions) which was placed on the Moon during the Apollo 11, 12, 14, 15, and 16 missions. "You don't often get to see active tectonics anywhere but Earth, so it's very exciting to think these faults may still be producing moonquakes". Researchers re-calculated the epicentres of these quakes and found that eight of them occurred near small cliffs produced along fault lines. These images show that there are boulders at the bottom of bright patches on the slopes of the faults. Impact craters, another common lunar feature, can help geologists better date these "wrinkle ridges" and their importance in the moon's cooling and shrinking activity.

NASA has flip-flopped between the moon and Mars, a victim of changing presidential administrations. The innermost planet Mercury boasts numerous thrust faults.

At the time, NASA Administrator Jim Bridenstine assured Pence that NASA would work hard to meet the deadline, expressing confidence that the SLS, or Space Launch System, would be ready for the job.
