Has NASA's Mars Curiosity Rover found something important on the surface of the Red Planet - perhaps even traces of life?
For years, NASA's Curiosity rover has patiently gathered samples on the surface of Mars. That leaves open the possibility that microorganisms once populated our planetary neighbour and still might.
NASA is remaining characteristically tight-lipped, but has confirmed the announcement will feature "new science results from NASA's Mars Curiosity Rover". "Curiosity has shown that Gale Crater was habitable around 3.5 billion years ago, with conditions comparable to those on the early Earth, where life evolved around that time".
The two studies build on and advance smaller detections of atmospheric methane and ancient organic compounds on Mars.
The surface of Mars may be inhospitable today, but there is strong evidence that the Martian climate once accommodated liquid water - which, as most of you will know, is one of the key components to life - to pool at the surface.
Methane, the simplest organic molecule, ranges "between 0.24 to 0.65 parts per billion, peaking near the end of summer in the Northern hemisphere", said the report, based on three years of data.
"Both these findings are breakthroughs in astrobiology", wrote Inge Loes ten Kate, of the University of Tübingen in Germany, in an accompanying commentary in Science. "We can find organic matter preserved in mudstones that are more than three billion years old", Siebach said.
Organic molecules are the building blocks of life, though they can also be produced by chemical reactions unrelated to life.
Future testing of the carbon isotopes in the methane could make the picture clearer, but for now we can't get too carried away - although the new results are a massive step towards discovering even more.
"This is the first time we've seen something repeatable in the methane story, so it offers us a handle in understanding it", Chris Webster of NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, said.
NASA's Curiosity Mars Rover drilled this hole to collect sample material from a rock target called "Buckskin" on July 30, 2015, during the 1060th Martian day, or sol, of the rover's work on Mars.
As with methane, there could well be non-biological explanations for the presence of carbon-containing molecules on Mars, such as geologic processes or impacts by asteroids, comet, meteors and interplanetary dust.
There is a seasonal variation to the methane that repeats, which means the methane is being released from the Martian surface or from reservoirs beneath the surface.
The scientists hope to find better preserved organic compounds with Curiosity or other rovers that would allow them to check for chemical signatures of life.
"With this new data, we again can not rule out microbial activity as a potential source", Webster said. The twin Vikings came up pretty much empty.
"We have greatly expanded our search for organic compounds, which is fundamental in the search for life", said Paul Mahaffy, study author and director of the Solar System Exploration Division at NASA's Goddard Space Flight Center.
However, they have become a more consistent side at the turn of the millenium, qualifying for all World Cups since the year 2006. I wish that Daniel will make Australia proud of him and that he'll make the soccer family proud of him too".
Some people might think the War of 1812 inspired the famous "1812 Overture" by the Russian composer Pyotr Ilyich Tchaikovsky. Rebuffing the criticism down the line, Mr Trump reportedly shot back: " Didn't you guys burn down the White House? ".
As you'd expect, the KEY2's many enhancements have resulted in a steeper price tag compared to last year's model. BlackBerry has also added in portrait mode so that you can add a blurry background to your photos if you'd like.
That is the revelation made by Lyon president Jean-Michel Aulas following reports that the Reds were closing in on the playmaker. However, Fekir has never started a competitive match for France so is unlikely to be a key player at the 2018 World Cup.
She had also worked for the social development ministry in Buenos Aires province and at a United Nations office in Panama. Her father Jorge Zorreguieta, Argentina's former agriculture minister, died a year ago .
Rovera was deeply sceptical over the coalition's claim that it had taken the necessary precaution to avoid civilian casualties. Amnesty wants to know if the RAAF has investigated the possibility of any civilian casualties as part of the Raqqa offensive.
And that allowed Kevin Durant to conserve some energy en route to a stunning game-high 43 points on 65.2 percent shooting. In his series debut, Iguodala had eight points on three-for-four shooting, two rebounds, one assist - and one scare.
The phone will be backed by a 4GB of RAM and 64GB of internal storage, which can be further expanded via microSD card slot. While the former model comes in Black and White colour variants, the latter is available in Black and Blue colour models.
Therefore, Game 3 might depend on whether or not he can provide offense for Cleveland alongside James, Love and company. That gives all of us a lot of confidence that he can come in and make an impact".

Media figures piled on Bee for the remark. "I talk fast, but you'll be fine", she said. "I hate that this distracted from them". She added that she would "anything" to help the kids in detention centers and apologized for the distraction.
While it's believed that Kaala will also help boost Rajinikanth's political career now that it's finally begun. The film, however, will have its full-fledged release in the state on Friday, The New Indian Express reported.
Warriors Are Halfway To Third NBA Title In 4 Years
Stephen Curry was the chief architect scoring 16 of his 33 points in the final quarter to ensure a commanding victory. But during Sunday's Game 2 win, the Warriors weren't happy with one incident involving Cleveland's Kendrick Perkins.
NASA Curiosity rover analysing Mars rocks again
The problem kept the robotic vehicle from extracting and analyzing Martian rock samples and severely affected the mission. The Curiosity Rover launched from Earth in November 2011 and landed on Martian soil on August 6, 2012.
