NASA dubs 2024 Moon mission 'Artemis', asks for $1.6 billion

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.

The quakes were quite strong too, some measuring over 5.5 on the Richter scale, an intensity associated with damaged buildings on Earth.

A new analysis of Apollo-era quakes on the Moon reveal that our satellite is probably still tectonically active. He noted that in Greek mythology, Apollo had a twin sister named Artemis, who served as the goddess of the moon.

By looking at the size and location of the tremors, the algorithm estimates the epicenter of the moonquakes.

The study was published on Monday in the journal Nature Geoscience.

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

NASA's Apollo 11 mission successfully landed the first humans on the moon on July 20, 1969.

Six out of the eight tectonically active moonquakes occurred when the Moon was at or close to its apogee, the point where it's most distant from Earth and where the diurnal and recession stresses create the most compression near the tidal axis. It's exactly the type of quake produced by the moon's fault scarps. They found it is less than 4 percent.

Quakes on Earth happen due to a very different reason. It came as a surprise to scientists when NASA's Lunar Reconnaissance Orbiter captured more than 3,500 images of faults on the surface that are younger than 50 million years old.

Astronauts would launch to the gateway and transfer to a lunar orbiter with a descent/ascent vehicle. Some of these images show landslides or boulders at the bottom of relatively bright patches on the slopes of fault scarps or nearby terrain. Because weathering gradually darkens material on the lunar surface, brighter areas indicate regions that are freshly exposed by an event such as a moonquake. "The moon is a three-day journey home, so if something goes wrong, we know we can make it home".

On the one hand, this timetable seems somewhat rushed, especially considering NASA's commercial partners have been experiencing delays with their crew capsules lately. The fault scarps themselves are also a clue. "I think it is very attractive that 50 years after Apollo, the Artemis program will carry the next man and the first woman to the moon".

The moon is not the solar system's only object shrinking with age. The moon, which orbits our planet at a distance of about 239,000 miles (385,000 km), has a diameter of about 2,160 miles (3,475 km), a bit more than a quarter of Earth's diameter.

A national expert familiar with NASA's long history of budget battles agreed that $1.6 billion is enough to move toward a 2024 launch, but in 2019 dollars is a far cry from NASA funding for the first manned moon missions half a century ago. "The President and Vice President's challenge to land on the Moon by 2024 reflects the urgent need for American leadership in space - it's an ambitious challenge but one I fully support and urge the American people to get behind". The agency will establish sustainable missions by 2028, then we'll take what we learn on the Moon, and go to Mars.

In addition to the groundbreaking research, NASA hopes that this new exploration will inspire the next generation of scientists.
