New study suggests Moon is still tectonically active

The video covers moon landing efforts, but also the concept of an orbital Deep Space Gateway as a stepping stone to Mars. These faults resemble small stair-shaped cliffs, or scarps, when seen from the. Meteor strikes, like those that caused the Moon's most distinctive features, still rain down today, so astronomers couldn't be sure whether the Moon was shaking itself, or being shaken by external forces. We conclude that the proximity of moonquakes to the young thrust faults together with evidence of regolith disturbance and boulder movements on and near the fault scarps strongly suggest the Moon is tectonically active.

Unlike Earth, the moon doesn't have tectonic plates. It isn't volcanic like Io or Venus (Venus is not known to be volcanically active at present, but the planet contains more volcanoes than any other location in the solar system).

Trump stated: "Under my Administration, we are restoring NASA to greatness and we are going back to the Moon, then Mars".

Over time, the lunar surface darkens due to weathering and radiation, so bright spots are areas where recent activity has exposed areas on the lunar surface.

Although we're familiar with active tectonics causing new land to be formed on Earth, such as the Krakatoa Archipelago, in the case of the Moon it's a contraction, not an expansion that's at play.

He acted in numerous television dramas and movies, including a role in the Hollywood film The Mortal Instruments: City of Bones. Some have also suggested that the producers of " Chase Me " should be held responsible for the incident.

A handful of similar examples were noted in photographs taken from Apollo craft as they orbited near the moon's equator, but it was not until 2010 that the Lunar Reconniassance Orbiter Camera, capable of recording details less than a metre across, revealed that such scarps can be found scattered across the whole globe. This is where additional tidal stress from Earth's gravity causes a peak in the total stress on the moon's crust, making slippage along the thrust faults more likely.

NASA could have humans back on the moon within the next five years under the latest orders from the Trump administration. "Such a young age raises the intriguing possibility that these thrust faults are now active", says Watters and colleagues in their paper.

Over the last several hundred million years the moon's interior has cooled, causing the surface to wrinkle as it shrinks. The instruments were retired in 1977, but in the seven years that they were active, they recorded 28 moonquakes, ranging from about magnitude 1.5 to 5 on the Richter scale-at the upper end, enough to damage a nearby spacecraft or moonbase.

Much as a grape wrinkles as it dries to become a raisin, the moon also wrinkles as its interior cools and shrinks.

"It's really remarkable to see how data from almost 50 years ago and from the [orbiter] mission has been combined to advance our understanding of the Moon while suggesting where future missions intent on studying the Moon's interior processes should go", said John Keller in a statement, study author and Lunar Reconnaissance Orbiter project scientist at NASA's Goddard Space Flight Center. These findings suggest moonquake surveys should absolutely be part of any long-term planning, to avoid any associated risks.
