In this episode of the Case for Mars, we look at the recently discovered lake on Mars, and how it was discovered. We discuss the MARSIS experiment, that is able to use Ground Penetrating Radar to detect changes in minerals, ice, or liquids underground. We also discuss what NASA thinks about this discovery, and whether or not life could exist in this lake. Thanks for watching! And consider subscribing if you enjoyed this video!

Researchers at the Italian Space Agency announced July 25 they have detected a large body of water almost a mile below Mars’ southern ice cap

A lake of liquid water has been detected by radar beneath the southern polar ice cap of Mars, according to a new study by Italian researchers from the Italian Space Agency, published in the journal Science. Evidence was gathered by the Mars Advanced Radar for Subsurface and Ionosphere Sounding instrument, also known as MARSIS, on the European Space Agency's Mars Express spacecraft. Between May 2012 and December 2015, MARSIS was used to survey the Planum Australe region, which is in the southern ice cap of Mars. It sent radar pulses through the surface and polar ice caps and measured how the radio waves reflected back to Mars Express.

Scientists think they've detected a sub-glacial lake around one of Mars' polar caps, but nobody's actually seen it yet.

One upside of recognizing and noting this ice is that future astronauts will have plenty of drinking water. (Audio: www.tregibbs.com. Black and white images are 5 km across; enhanced color images are 1 km.) https://uahirise.org/ESP_053642_2225

This impact crater looks amusingly like a tadpole because of the valley that was carved by water that used to fill it. When the water level inside the crater increased, it breached the crater wall, flowed outward and formed a valley. Sometimes, the water may flow in the opposite direction, like from a channel into a crater. It is often difficult to differentiate between inlet and outlet channels, but water always flows downhill. In this particular case, we can infer that water is flowing outward because we have the necessary terrain-height information. When studying these images in detail, scientists can gain a better understanding of the strength of the flooding water that carved the channels, and better understand the history of water activity in this region of Mars.

Saturn's rings are a celestial river flowing above the clouds of their planet. Here is the story of how we learned that.

NASA’s Mars Reconnaissance Orbiter recently discovered an easily accessible water source on the Red Planet, suggesting that future missions would be able to attain drinking water and make rocket fuel. NASA issued a statement saying that the MRO had discovered “eight sites where thick deposits of ice beneath Mars’ surface are exposed in faces of eroding slopes." These ice deposits could help scientists gather more information about underground ice sheets which were previously undetected. https://www.digitaltrends.com/cool-tech/nasa-water-mars/ http://www.wochit.com This video was produced by YT Wochit News using http://wochit.com

The quest to find water on Mars continues as researchers report the likely presence of ice sheets on the Red Planet. Data from two orbiting spacecraft revealed ice cliffs at least 100 meters (328 feet) thick, which may provide information about Mars’ past climate. “They might even be a useful source of water for future human exploration of the Red Planet,” Colin Dundas, research geologist with the U.S. Geological Survey, said. ;/It was Dundas who spotted a pale band of blue peeking out from the globe’s rusty complexion in high-resolution photos, taken a few years ago by the Mars Reconnaissance Orbiter. The spacecraft takes detailed pictures of the Martian surface suing the High-Resolution Imaging Science Experiment (HiRISE) shooter. https://www.geek.com/news/martian-glaciers-could-help-unlock-planets-history-1727768/?source http://www.wochit.com This video was produced by YT Wochit News using http://wochit.com

Forget rocky worlds like Earth and Mars. New discoveries about icy worlds like Europa and Enceladus make them the ideal candidates for the search for life in the Universe. In fact there could be hundreds, or even thousands of times more worlds out there with ability to support life. Of course, there’s a problem, how do we search for life when it’s hidden beneath kilometers of ice?

The Red Planet is cold, dry and airless today, but it certainly seemed to have liquid water there in the ancient past. Of course, wherever we find liquid water here on Earth, we find life. At the bottom of the ocean, where the crushing pressures would kill us in a moment. In steaming volcanic vents. Beneath glaciers, deep underground, even huddled in nuclear reactor cooling tanks. NASA’s Mars exploration program has been following the story of water. Opportunity and Spirit discovered evidence that Mars had liquid water in the ancient past. And the Curiosity Rover doubled down on that, finding minerals that indicate there was water on the surface of Mars for a long time. But then, long ago, the conditions changed, Mars lost its atmosphere, became cold, dry and inhospitable to life. It’s possible that life could still be there on Mars, huddled underground in salty reserves that prevent the water from freezing or evaporating. But so far, scientists haven’t found it yet. This shows that life on rocky worlds is tenuous at best. Too close to the star, or too far. Not a thick enough atmosphere, or too thick, creates a world that’s inhospitable to life. And even if a world was, briefly a place worth calling home, main sequence stars are constantly putting out more radiation, shifting the habitable zone farther out. Think about how long Earth will be habitable. Life crawled out from the oceans 430 million years ago, and planetary scientists estimate we’ve only got another 500 million to a billion years before the Sun gets too hot and boils the oceans dry. But now we’re discovering there are other places in the Solar System to look for life - water worlds. In fact, the number of these places, and the amount of liquid water on them is difficult to wrap your brain around. The Earth is a desert compared to the amount of liquid water that’s out there in the Solar System. Europa alone has 2-3 times as much water on Earth. And this life could be safe and sound, protected from radiation, meteor impacts and nearby supernovae for billions of years. Long after the Sun has burned out and faded away.

A new study published Nov. 20 in the journal Nature suggests dark streaks on Mars thought to indicated subsurface water may represent dry flows of sand.

The red planet might not actually have liquid water on its surface as scientists previously reported.

ENCELADUS, SATURN — Scientists looking at data pulled from NASA's Cassini spacecraft may have found out how Saturn's ocean moon Enceladus remains geologically active. The research, published in Nature Astronomy, suggests that tidal currents flow through the moon's porous core, where the friction between rocks generate heat that warms the ocean. According to the European Space Agency, this tidal heating is primarily caused by the gravitational pull of Saturn. Writing in 2008, the space agency speculated that the deep sea vent theory could apply to life on Enceladus. When applied to Earth, this suggests life originated from chemical, heat and tidal interactions beneath the seabed. NASA previously said Enceladus has all the ingredients for life, reported CNET, citing the space agency. ----------------------------------------­--------------------- TomoNews is your best source for real news.

A new study based on information gathered by the Cassini spacecraft furthers hope for the habitability of Saturn’s moon Enceladus.

Jupiter's moon Europa may be a habitable world. Galileo spacecraft data suggest that an ocean exists at a relatively shallow depth beneath Europa’s icy surface, and geological activity may permit the 'ingredients' necessary for life to be present within this ocean today. Because of the potential for revolutionizing our understanding of life in the solar system, future exploration of Europa has been deemed an extremely high priority for planetary science. NASA funded the California Institute of Technology Jet Propulsion Laboratory and the Johns Hopkins University Applied Physics Laboratory to perform studies of the design and implementation of several mission concepts to explore Europa. Over the past two years, two concepts were studied in detail: an orbital mission, and a mission in Jupiter orbit that makes multiple Europa flybys that we term the 'Europa Clipper'. The orbiter concept is well suited to perform scientific observations that are best made from orbit, such as geophysical measurements. In comparison, the Clipper concept is best suited to measurements that can be made of local to regional areas distributed across the satellite, such as remote sensing of specific surface features. The Clipper was judged to have the greater scientific breadth and to be the more cost effective for the expected science return. The Clipper would make at least 32 orbits of Jupiter, each time swooping 100 km or closer to Europa. This strategy minimizes the radiation exposure and decouples science acquisition from data downlink, which correspondingly decreases the power needed for the flight system operation. The resulting flight system is a compact design that minimizes radiation shielding and overall system mass while maintaining robust technical margins. Moreover, the flight system would use a modular architecture, simplifying hardware procurements, implementation, and system integration and test. The model payload would consist of a radio subsystem for gravity science, a magnetometer, Langmuir probes, an ice penetrating radar, a shortwave infrared spectrometer, a neutral mass spectrometer, and a stereo camera. In addition, programmatic elements of the payload (a high-resolution camera capable of performing stereo imaging and a thermal imager) would determine surface characteristics of Europa at lander scales, to aid design of a future lander mission to Europa and to inform the potential for safe and scientifically compelling landing sites. It is envisioned that the Clipper mission would be launched in the 2022 timeframe.
