What Does New-Found Water on Mars Mean for life?

  • What Does New-Found Water on Mars Mean for life?

    5:18

    Life, as we know it on Earth, needs liquid water to survive. In 2015, NASA scientists announced the historic discovery stating that, under certain circumstances, liquid water was found on Mars.

    The discovery could not have been possible without a rover called Curiosity that landed on Mars in 2012, and it has since found building blocks of life in an ancient lake bed.

    DCODE the continuing journey of Curiosity and the hunt for life on the red planet.

  • Scientists find lake of liquid water on Mars

    9:47

    There's a lake on Mars, it's been revealed today. It's not very big, but it is described as a proper body of liquid water probably around 22 metres wide and at least a metre deep. Scientists from the National Institute for Astrophysics say it's the first conclusive proof that H2O exists there currently, even though there's evidence of it having been there in the past. Water, of course, is a prerequisite for life as we know it.. Ed Howker has the details, and we talk to astrobiologist Manish Patel and Tom Kerss, an astronomer based at the Royal Observatory Greenwich.

  • For 10 Years NASA Has Been Capturing Images of Mars and They Now Reveal the Planets Amazing Beauty

    5:41

    On August 12, 2005, NASA launched an unmanned spacecraft. The idea was for them to capture photos of the unexplored planet. Mars is also known as the Red Planet. This is because the planet has a reddish hue when observed in the night sky. It is the fourth closest planet to the sun, right beside Earth, which is the third. Mars is just over half the size of Earth. It has just about 38 percent of the surface gravity than Earth does. Mars has water; however, because of the low atmospheric pressure on Mars, it has only 1 percent of the water that Earth does.

    On Mars, there is a lot of water ice. Scientists believe that the Mars polar caps contain a great deal of ice. They believe that if all of the ice at the south pole of Mars were to melt, it would cover the whole planet in 36 feet of water. In 1610, a scientist was able to examine Mars through a telescope. It was then that the Italian astronomer Galileo made his breakthrough. In 1659, a Dutch scientist named Christiaan Huygens was the first scientist to identify a Martian feature, the volcanic plain of Syrtis Major. It was then determined that the length of a day on Mars was 24 hours and 30 minutes.

    We couldn't wait to get spaceships to Mars to explore. This started the Cold War Space Race between the USA and the USSR. The Soviets were the first to launch a probe to Mars in 1961, but the Americans were the first to find success with Mars-bound spaceships. The Soviet Union launched five missions to Mars between 1960 and 1962, but all of them failed. The US sent their first ship to Mars in 1964, but that one failed also. Later in 1964, the US spaceship, Mariner 4, made it to Mars. They had a successful flyby in July 1965. When the craft returned to Earth, it had detailed pictures of the surface of the planet.

    After the first flyby of Mars, more and more missions were sent to the planet. With technology, the missions were more successful. Regardless of the success, two out of three missions failed. In 1971, Mariner 7 managed to orbit around the whole planet. In 1976, Viking 1 and 2 were able to land on the surface of Mars. Viking 1 managed to get the first ever, color photo of the planet's surface.

    In 1966, the Mars Global Surveyor spaceship was sent to space for a mapping exercise. It wasn't going to land on Mars, but it was going to find optimal spots for spacecraft to land in the future. Finally, in 2008, the American spacecraft Phoenix landed in the northern pole of Mars. It was a robotic vehicle that had a probing arm. It was then that we confirmed that there is water on Mars in the form of ice.

    This spacecraft launched from Cape Canaveral, Florida in August 2005, and it cost $720 million to build. The spaceship was 21-feet tall, and it contained a radio antenna dish that was 10-feet in diameter. It was also fitted with 220 square feet of solar panels. It weighed 4,800 pounds when it was launched, and half of that was fuel to power the necessary 20 thrust engines.

    When the Orbiter was launched, it took seven months to get to Mars. The operation lasted for five months. The main objective of the Orbiter was to find out more about the past levels of water n Mars. Scientists knew that the water ran across the surface of the planet earlier. Now they wanted to know if there was still water present, allowing for living organisms to thrive on the planet for long periods of time.

    The purpose of the mission was to measure the weather trends on the Red Planet. They wanted to know more about the seasonal changes and the makeup of the polar ice fields. They also wanted to search for dangerous landing areas, such as protruding rocks.

    In 2008, the Phoenix that had been launched in August 2007 and it had a successful soft landing on Mars. They managed to get a photo of Phoenix as it parachuted down to Mars. The area where it landed looked a lot like the Earth's polar regions that are covered with permafrost. The robotic arm was dropped to take samples of the soil on Mars. These samples confirmed that there was ice just below the surface.

    During the mission, the spacecraft was able to capture 2,054 images of the Red Planet. The photos told them a lot about the planet. There are pictures of the areas where there was once water. There are a few frozen spots on the planet that are sheltered from the sun's rays by deep folds of dunes. There is a photo that was taken in May, which is the Martian spring, where snow and ice on the ground are actually frozen carbon dioxide, also known as dry ice. For Ten Years NASA Has Been Capturing Images Of Mars – And They Reveal The Planet's Amazing Beauty.

    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.

    New Discovery Of Water On Mars Could Help Future Missions To The Planet | Mach | NBC News

  • Life on Mars? | Dr Matt Balme

    44:21

    “...we want to understand the geological history of the area and look for signs of life”
    - Dr Matt Balme (Open Univeristy, ExoMars Rover Science Operations Working Group member)

    ExoMars is a European Space Agency mission to address the question of whether life has ever existed on Mars.

    In March 2021 the Rosalind Franklin rover will land on the surface of Mars, seeking out geologically interesting sites to drill below the surface, to determine if life ever existed on our neighbour planet.

    Speaking at the UCD School of Geography's 'Shaping the Future' seminar series, Dr Matt Balme, planetary scientist and ExoMars Rover Pan-Cam camera operator, spoke on the question of life at mars and the purpose of the mission.

    In this lecture he presents examples of both modern and ancient martian landscapes, and states the evidence for liquid water having modified the surface over the past few millions or tens of million years.

    He is a senior lecturer at Open University, working in the OU Planetary Environments research group - in the OU School of Physical Sciences. His main research interest is to understand the recent geological history of Mars and how climate has shaped the surface.

    At the end of the 19th century, scientists assumed that there was a developed civilization on Mars, similar to ours. Giovanni Schiaparelli from Italy noticed straight, long lines on the surface of the Red Planet through a telescope and thought they were man-made channels. Later, the astronomer Percival Lowell suggested that a Martian civilization had built an extensive network of aqueducts to deliver water to its settlements from the polar caps of the planet. It is no wonder that, given such a point of view by science, the radio adaptation of H.G.Wells' War of the Worlds, in which the author describes how Martians conquer Earth, caused a real panic among many listeners in the US. They seriously thought that Mars was attacking!

  • Liquid water lake found on Mars, What does this mean for life?

    5:44

    Liquid water lake found on Mars,What does this mean for life?
    Researchers have found evidence of an existing body of liquid water on Mars.
    What they believe to be a lake sits under the planet's south polar ice cap,
    and is about 20km across.
    Previous research found possible signs of intermittent liquid water flowing on the martian surface,
    but this is the first sign of a persistent body of water on the planet in the present day.
    Lake beds like those explored by Nasa's Curiosity rover show water was present on the surface of Mars in the past.
    However, the planet's climate has since cooled due to its thin atmosphere,
    leaving most of its water locked up in ice.
    The result is exciting because scientists have long searched for signs of present-day liquid water on Mars,
    but these have come up empty or yielded ambiguous findings.
    It will also interest those studying the possibilities for life beyond Earth - though
    it does not yet raise the stakes in the search for biology.
    The discovery was made using Marsis,
    a radar instrument on board the European Space Agency's Mars Express orbiter.
    It's probably not a very large lake,
    said Prof Roberto Orosei from the Italian National Institute for Astrophysics, who led the study.
    Marsis wasn't able to determine how thick the layer of water might be,
    but the research team estimate that it is a minimum of one metre.
    This really qualifies this as a body of water.
    A lake, not some kind of meltwater filling some space between rock and ice,
    as happens in certain glaciers on Earth, Prof Orosei added.
    How was it found?
    Radar instruments like Marsis examine the surface and immediate subsurface of the planet
    by sending out a signal and examining what is bounced back.
    The continuous white line at the top of the radar results above marks the beginning of the South Polar Layered Deposit;
    a filo pastry-like accumulation of water ice and dust.
    Beneath this, researchers spotted something unusual 1.5km under the ice.
    In light blue you can see where the reflections from the bottom are stronger than surface reflection.
    This is something that is to us the tell tale sign of the presence of water, says Prof Orosei.
    What does this mean for life?
    Nothing definitive. Yet.
    Dr Manish Patel from the Open University explained:
    We have long since known that the surface of Mars is inhospitable to life as we know it,
    so the search for life on Mars is now in the subsurface.
    This is where we get sufficient protection from harmful radiation,
    and the pressure and temperature rise to more favourable levels.
    Most importantly, this allows liquid water, essential for life.
    This principle of following the water is key to astrobiology - the study of potential life beyond Earth.
    So while the findings suggest water is present, they don't confirm anything further.
    We are not closer to actually detecting life, Dr Patel said,
    but what this finding does is give us the location of where to look on Mars.
    It is like a treasure map - except in this case, there will be lots of 'X's marking the spots.
    The water's temperature and chemistry could also pose a problem for any potential martian organisms.
    In order to remain liquid in such cold conditions
    (the research team estimate between -10 and -30 Celsius where it meets the ice above),
    the water likely has a great many salts dissolved in it.
    It's plausible that the water may be an extremely cold, concentrated brine,
    which would be pretty challenging for life,
    explained Dr Claire Cousins, an astrobiologist from the University of St Andrews, UK.
    What next?
    While its existence provides a tantalising prospect for those interested in the possibility of past or present life on Mars,
    the lake's characteristics must first be verified by further research.
    What needs to be done now, explained Dr Matt Balme from the Open University,
    is for the measurements to be repeated elsewhere to look for similar signals, and, if possible,
    for all other explanation to be examined and - hopefully - ruled out.
    Maybe this could even be the trigger for an ambitious new Mars mission to drill into
    this buried water-pocket - like has been done for sub-glacial lakes in Antarctica on Earth, he added.
    Scientists have previously claimed to find bacterial life in the buried depths of Antarctica's Lake Vostok,
    but drilling on Mars would make for an ambitious project indeed.
    Getting there and acquiring the final evidence that this is indeed a lake will not be an easy task, said Prof Orosei.
    It will require flying a robot there which is capable of drilling through 1.5km of ice.
    This will certainly require some technological developments that at the moment are not available.

  • Are We About to Find Life on Mars?

    1:9:07

    Over the past six months, numerous articles have reported weird anomalies in the atmosphere of Mars, from an outburst of methane in June 2019 to patterns in oxygen concentrations that cannot be explained by any known atmospheric or surface processes on the Red Planet. Perhaps more intriguing is the Viking Lander (Viking LR) experiment. In 1976, each of the two Viking landers performed experiments on Martian soil samples. The samples tested positive for metabolism, and researchers recently claimed that like on Earth, this is a sign for the presence of a Martian life. Finally, an Ohio scientist claims to have found photographic proof of insect and reptile-like life on Mars. This controversial result has been discussed at length in the media, even though most scientists rejected it.

    What does this mean? Are we on the verge of announcing the most profound story since humans first wondered about the existence of life elsewhere? Or are these coincidences that can be explained by geological processes, failed experiments or pareidolia?

    We invited two SETI Institute scientists who are experts on Mars to discuss these exciting and out of this world results. Biologist Kathryn Bywaters who has studied life in some of the most extreme environments on Earth and planetary scientist Pascal Lee who focuses on water on Mars and human exploration of the Red Planet. Both scientists will tell us if indeed we are about to discover life on Mars and the consequences of this significant discovery.

  • New Mars Curiosity Rover Pictures

    10:05

    We follow the Curiosity Rover on Mars as it climbs up a Martian mountain named Mount Sharp. We have selected only the clearest footage from Mars to give you a sense of actually being there alongside Curiosity. All the places that NASA has explored have been given nicknames, which you will see in the video. Some of the images have been 'white balanced' by NASA to give geologists a clearer view of the rocks.

    A quick summary of the Journey:

    Landing in the Gale Crater, Curiosity heads towards Yellowknife Bay, taking its first drive over 'Glenelg'. In Yellowknife Bay, Curiosity finds the first evidence that the Gale Crater was once filled with salty water.

    Curiosity goes on to explore the Bagnold Dunes and crosses through the Naukluft Plateau into Murray Buttes where it begins to ascend Mount Sharp. Climbing on top of 'Vera Rubin Ridge' provides Curiosity with a magnificent view, from where we started in the Gale Crater.

  • Martian Mud: Recent Discovery of Organic Matter on Mars

    55:42

    Jennifer Eigenbrode discussed NASA's Curiosity rover's recent discovery of organic carbon molecules, some of the building blocks of life, in mudstones from a 3-billion-year-old Martian lakebed. She discussed how it might have been preserved and what the source might be.

    - Jennifer Eigenbrode is an interdisciplinary astrobiologist at NASA's Goddard Space Flight Center. She specializes in organic biogeochemistry of Martian and ocean world environments. Eigenbrode received her undergraduate degree in geology at James Madison University, her master's in geological sciences at Indiana University in Bloomington, and her doctorate in geosciences from Penn State. As a sample analysis at Mars Collaborator and participating scientist for the Mars science laboratory mission, she has focused on the in situ detection and preservation of organic molecules in the radiated sediments at the Martian surface. Her work aims to improve planetary mission design, contamination control and instrument measurements that will enable the search for life beyond Earth.

  • Life on Mars? Rock varnish might have an answer

    2:10

    If life exists on Mars, it still hasn’t showed itself, but recent evidence from the red planet increasingly supports the possibility. Life could have developed there. Most of the conditions are right and nothing found so far rules out the possibility, either in the distant past or today.
    If something is or was alive there, it’s probably tiny. Since microbes make up the vast majority of life on Earth, microbes are the most likely thing to find somewhere else. It’s not so easy figuring out what “alive” means on another planet—let alone finding a living microbe.
    The upcoming Mars 2020 mission and its rover-based mobile laboratory will take another giant step toward answering the question. First, though, science needs to answer some questions about life here on Earth. It turns out that the dark, hard manganese oxide in varnish coating cliff faces and rocks throughout the American Southwest and elsewhere has a lot to say about the subject.

  • NASA rover detects high amounts of methane on Mars, which could indicate signs of life

    5:16

    NASA scientists say its Curiosity rover discovered high amounts of methane gas on Mars. On Earth, the gas is typically produced by living things. CBS News space consultant Bill Harwood joined CBSN to discuss if this observation could mean there's life on Mars.

  • Why We May Have Already Found Life On Mars with Dr. Patricia Ann Straat

    42:38

    With the recent findings of seasonal methane blooms on Mars and now unusual readings of unexplained oxygen levels, the question of is there microbiological life on the red planet? goes unanswered. In 1976, NASA sent Viking 1 and Viking 2 with four types of biological experiments. Of these experiments, the Labeled Release Experiment returned positive results on both landers, however the control tests could not confirm the results. Did the Viking landers find life on Mars?

  • Mars has a vast liquid lake beneath its southern pole, scientists believe

    3:10

    It's an extraordinary development in the search for life on Mars.
    Scientists have discovered a giant lake of water beneath ice near the red planet's south pole.
    Using ground-penetrating radar from an orbiting spacecraft, an Italian team picked up signs of a 20km-wide body of liquid water.
    The salt-laden lake is hidden about one-and-a-half kilometres beneath the planet's southern polar plains.
    Whether it's a relic of past oceans or part of a bigger network of lakes remains a mystery.

    “Since its daredevil landing on Mars last summer, NASA’s Curiosity rover has been avidly exploring its new home in Gale Crater. But there’s been one worry that several people have voiced since Curiosity launched — what if the rover contaminates the surface of Mars with Earth life?”

    Microbial stowaways to Mars identified

    “Dozens of microbial species may have accompanied the Curiosity rover to Mars, where it landed in August 2012. The stowaways withstood spacecraft cleaning methods before the rover's launch, although no one knows for sure whether the bacteria survived the inter-planetary ride.”

  • Scientists discover giant liquid water lake on Mars | ITV News

    2:13

    Scientists have discovered a huge 12-mile wide lake beneath the southern ice cap of Mars.

    It is the first time a large stable body of liquid water has been confirmed to exist on the Red Planet.

    Dissolved salts are thought to keep the water fluid, despite having a temperature below freezing point.

    The discovery, which has major implications for the chances of life surviving on Mars, was made by an orbiting European probe using ground-penetrating radar.
