MARS: The Next Frontier - NASA's Curiosity Finds Liquid Water Below Mars' Surface!

April 14, 2015 -  MARS - New measurements of Martian weather and soil conditions suggest the soil is damp with liquid brine, which can remain liquid when temperatures drop below freezing. The finding contradicts theories that it’s too arid and cold for water on the Red Planet.

The measurements, based on a full year’s study of the planet’s temperature and humidity by NASA’s Curiosity rover, indicate that conditions at the Gale Crater are “favorable for small quantities of brine to form.” The brine is created when the salt perchlorate absorbs water vapor from the atmosphere and then lowers the freezing point of water. When mixed with calcium perchlorate, liquid water can exist down to around -70 Celsius.

“Liquid water is a requirement for life as we know it, and a target for Mars exploration missions,” said the report’s author, Javier Martin-Torres of the Spanish Research Council, in a statement. “Conditions near the surface of present-day Mars are hardly favorable for microbial life as we know it, but the possibility for liquid brines on Mars has wider implications for habitability and geological water-related processes.”


No foolin'! These mineral veins are more clues to ancient wet environment at Gale crater.

The new measurements suggest that until just after sunrise during winter nights, temperatures and humidity levels are just right for brine to form. Curiosity first detected the salt perchlorate in 2008 but the weather data studies helped scientists understand that conditions would be high enough to produce brine. NASA said that when relative humidity gets above a threshold level, salts can absorb enough water molecules to become dissolved in liquid.

“The soil is porous, so what we are seeing is that the water seeps down through the soil. Over time, other salts may also dissolve in the soil, and now that they are liquid, they can move and precipitate elsewhere under the surface,” Marten Bo Madsen, a senior Mars scientist at the University of Copenhagen, told the Guardian.

The weather data, released under the title “Transient liquid water and water activity at Gale Crater on Mars,” was published on Monday on Nature.com.

“Gale Crater is one of the least likely places on Mars to have conditions for brines to form, compared to sites at higher latitudes or with more shading. So if brines can exist there, that strengthens the case they could form and persist even longer at many other locations,” said co-author of the report, Alfred McEwen, principal investigator of High Resolution Imaging Science Experiment at the University of Arizona, Tucson, in a statement.

The Gale Crater is located just south of Mars’ equator and is 154 kilometers in diameter, with the rim almost five meters high. In the middle of the crater is Mount Sharp, which Curiosity is climbing.

Despite this finding, however, life on Mars is improbable. Scientists say if life existed, it died out about one billion years ago. About four billion years ago, Mars lost the benefit of a thick atmosphere and a magnetic field, like on Earth, that protected the atmosphere from cosmic radiation from the Sun. Radiation now penetrates one meter into the Martian surface and would kill even the most robust microbes known on Earth.

NASA said that since Curiosity landed on Mars a year ago, it has found evidence of ancient streambeds and a lakebed environment that, more than three billion years ago, offered conditions favorable for microbial life. The rover is examining Mount Sharp for evidence of how ancient environmental conditions evolved. - RT.
 



UFO SIGHTINGS: UFOs Or Clouds - Stunning Formations Seen In The Skies Over Ullapool, Scotland?!

Are they clouds of UFOs?

April 14, 2015 -  ULLAPOOL, SCOTLAND - Conspiracy theories have emerged around UFOs after a picture was taken above the west coast of Scotland.

Neil Borthwick captured the pictures of flying-saucer shaped clouds from his home in Ullapool last night after he saw them above Loch Broom.

The 54 year old soon posted them online, prompting conspiracy theories to blossom.

William Topping, from South Shields, wrote on Facebook: “You might be laughing but these exact same cloud formations turned up on several different sites today and were witnessed at over 20 locations in the northern hemisphere, all within 60 minutes of each other.

“And as stated, absolutely identical, carbon copies.

“Now that is spooky…

“So much so, NASA took a whole load of them down within minutes of publishing.”




The reality may be somewhat less interesting.

The rare lenticular clouds, which are rare in the UK, are created in certain conditions when air is pushed upwards by a mountain.

They are one of the most common causes of UFO reports.

Mr Borthwick was less taken in, unwilling to believe aliens would visit Ullapool.

He said: “It was shortly after 8pm, I just happened to glance at the window and I thought, that’s interesting.

“I went out onto the street beyond mine to get a photo. I’d reckon the clouds were in view for up to half an hour.

“There were other people taking photos of the sky – the sunset was spectacular apart from the fact the clouds were there.

He added: “I’m not suggesting for one minute we are being invaded by aliens. If they ever did come I’m not sure they would land in Ullapool anyway.” - Press and Journal

WATCH: Triangle-shaped UFO sighting over Sevilla, Spain - April 11, 2015.

Eye-witness report:
A friend was visiting from San Francisco, California on Wednesday April 8th and 9th, 2015. She took numerous photos during the trip. Once I saw the photos I observed an oval shaped object in the sky. The object was in three different photos. This was not seen by the naked eye while taking the photos, she had no idea about the objects until they were seen in the photos afterwards.
