About 47 years ago, Harrison Schmitt became the only scientist to ever walk on the moon. Now, the geologist and professor is studying an extensive landslide on Mars, almost 250 miles wide, that formed about 400 million years ago.
A human hasn't landed on the moon since 1972, but NASA's Artemis program aims to land the first woman and the next man on the lunar surface by 2024. Part of that process involves upgrading the classic spacesuits worn by Apollo-era astronauts in the 1960s and 70s.
The return of humans to the moon, as well as ongoing robotic missions, may require using resources already on the lunar surface. The moon's south pole is of particular interest because of ice deposits in craters there.

India has located the lander from its Chandrayaan-2 mission to soft land a rover on the moon but has not yet been able to establish communication, India's space agency said.
India's historic attempt to soft land a rover on the moon may have ended in failure moments before landing and scientists scrambled to analyze the final communication from Chandrayaan-2.
When it comes to brightness, it's hard to outshine the sun. But in new NASA images, the moon sparkles brighter thanks to a telescope that can detect high-energy radiation.
The night skies in August are full of celestial wonders, including bright planets and a meteor shower.
You've heard of men on the moon -- but what about moss piglets?

Fifty years after humans first stepped onto the moon during the Apollo 11 mission, NASA has created a goal of landing the first woman and next man on the moon's South Pole by 2024. NASA has dubbed this path back to the moon Artemis, after Apollo's twin sister in Greek mythology.
India has successfully launched a mission to soft land a rover on the moon, in a landmark moment for a nation trying to become a space superpower.
Saturday is the anniversary of what many consider to be the greatest achievement of the 20th century.
