Trump Wants an Extra $1.6 Billion for NASA’s Mission to the Moon

Trump Wants an Extra $1.6 Billion for NASA’s Mission to the Moon”

They compared the data with more than 12,000 photos taken by NASA's Lunar Reconnaissance Orbiter (LRO) since 2009 and determined the moon is 164 feet "skinnier" than it was in the early 1970s.

This, in turn, causes its surface to wrinkle, similar to a grape that shrivels into a raisin. In the process, the lunar crust breaks, producing thrust faults - a type of fault where ground from one section of the crust is pushed up over an adjacent section. Instead, as the moon's interior has cooled over the last several hundred million years, it has caused the surface to wrinkle as it shrinks.

For the next wave of lunar missions, the space agency wants its moonwalkers to reflect today's astronauts, thus the name of Apollo's sister. The study was published May 13 in Nature Geoscience.

"I think it is very handsome that 50 years after Apollo, the Artemis program will carry the next man and the first woman to the Moon", NASA administrator Jim Bridenstine said. "I have a daughter who is 11 years old, and I want her to be able to see herself in the same role as the next women that go to the Moon". On Earth, the quakes would have ranged in magnitude from about 2 to 5. They found that at least eight of the moonquakes matched nearly perfectly with scarps, suggesting that they were produced by genuine tectonic activity, rather than processes deep within the moon's interior or from asteroid impacts. This was close enough for the team to conclude that the faults likely caused the quakes. The Moon and Earth always tug on each other, but the stress on the faults is greatest when the Moon is at apogee, its farthest point from Earth. The researchers ran 10,000 simulations to calculate the chance of a coincidence producing that many quakes near the faults at the time of greatest stress. They found it is less than 4 percent.

The researchers started by applying a new algorithm - one that was designed for working with inaccurate data from Earth-based seismic networks with few sensors - in order to re-find the epicentres of the 28 Apollo quakes.

"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. Some of these images show landslides or boulders at the bottom of relatively bright patches on the slopes of fault scarps or nearby terrain.

NASA announced Monday that Trump challenged the agency to land at the south pole of the moon by 2024. Future research can also help scientists understand what is occurring on other celestial bodies like the planet Mercury, which is also shrinking and has thousands of thrust faults. They exist on Mars, and of course they're all over Earth.

The LRO images also revealed surface features that support the theory that the Moon continues to be active.

It would be followed by a version that could bring people to the Moon along the same timeframe as NASA's proposed 2024 return, Mr Bezos said. These faults resemble small stair-shaped cliffs, or scarps, when seen from the lunar surface.

The Moon isn't the only world in our solar system experiencing some shrinkage with age.
