NASA’s InSight robot is fighting against Mars to save a vital instrument

  NASA’s InSight robot is fighting against Mars to save a vital instrument NASA's InSight lander has been resting safely on Mars for nearly a year now, and it's doing some seriously great work. Most of the robot’s suite of sensitive instruments have been working as intended, sending back data and recordings of seismic activity on the dusty planet. However, one of the tools, called the “mole,” has fallen well short of expectations.The instrument is supposed to hammer itself into the surface, pushing itself to a depth of up to 16 feet to gather temperature readings. Unfortunately, the probe has failed to bury itself any deeper than about a foot, but NASA thinks it knows why.

Deep in the South African gold mines that line the Vaal River basin, an international team of scientists, including Belgian biologist Gaetan Borgonie, are looking for what they call extreme life — life where no one believed it could exist.

The gold mines are the deepest man-made holes on earth, and they allow the scientists access to Earth's hidden subterranean world. To get to the bottom of the Moab Khotsong mine, the scientists pile on to an elevator called the cage, jammed in along with the gold miners heading to work. The cage drops slowly at first, then faster and faster, descending 450 stories underground. For comparison, the world's tallest building, Dubai's Burj Khalifa, has only 163 floors.

NASA’s planet-hunting probe joins search for alien life

  NASA’s planet-hunting probe joins search for alien life NASA's newest planet-hunter is taking part in the hunt for intelligent aliens. The space agency's Transiting Exoplanet Survey Satellite (TESS) mission will collaborate with the $100 million Breakthrough Listen project in the search for extraterrestrial intelligence (SETI), the teams announced on Wednesday.

Guided only by the light of their helmet lamps, the scientists walk miles through a vast maze of tunnels, before taking a chairlift even deeper into the Earth. Here, almost two miles underground, they find rock that was formed three billion years ago. Borgonie and his team collect samples of water trapped in the ancient rocks, untouched by humans.

In 2011, they made a break-through discovery: Never-before-seen worms were found living in a pocket of water 5,000 years old. The worms were living without sunlight in unbearable heat. Until that point, no one thought animals could exist that deep in the planet's crust.

It wasn't just worms. Four years later, Borgonie and his colleagues found more animal life in other South African gold mines: an arthropod; a flatworm; and a tiny crustacean, only about one sixty-fourth of an inch. These are among the deepest living creatures ever discovered.

In recent years, Mars has looked more and more like a place where past life might have flourished. Now, some researchers believe the Red To get to the bottom of the Moab Khotsong mine , the scientists pile on to an elevator called the cage, jammed in along with the gold miners heading to work.

The discoveries have important implications for where else extreme life might exist — not just the deep subsurface of Earth, but elsewhere in the solar system. That includes Mars, a planet that has harsh conditions similar to the bottom of the gold mines.

"Because it means if they can do it here, why would they not be able to do it there?" Borgonie told 60 Minutes correspondent Bill Whitaker in a video.

Borgonie said Mars likely doesn't have multicellular organisms, but rather, simple life forms, like bacteria. He also thinks the organisms would most likely live deep underground. Because the atmosphere on Mars has been blown away by solar wind, there is no longer any water above ground. Without an ozone layer, the sun's rays would destroy anything organic. But there is still water underground on Mars, much like the water trapped deep in the rocks at the Moab Khotsong mine.

Landslides on Mars might not be evidence of ice after all

  Landslides on Mars might not be evidence of ice after all When scientists studying Mars discovered a massive landslide on the Red Planet they thought it looked familiar. The cascading material had carved long, curved ridges, and the area was eerily similar to some landslides that have been observed here on Earth. What made that comparison particularly exciting was the fact that on Earth, landslides like this are often associated with the presence of ice beneath the ground. This, researchers believed, was a clue that something similar may have happened on Mars some 400 million years ago when the landslide is thought to have occurred.

Borgonie thinks the chance of finding these simple life forms is much higher than many scientists admit — and NASA has been following their work closely.

"Life always finds a way," Borgonie said. "Make no mistake."

Mars at dawn: This NASA Curiosity rover image will enchant your heart .
The Curiosity rover gifted us with a gorgeous look at a new day dawning far, far away.Mars is barren and dry. Earth is luxuriating in water. Sometimes these two very different planets find common ground under the light of the same sun. NASA's Curiosity rover just captured one of those moments in a stirring new image showing dawn breaking across Gale Crater.
