White House Briefed On Potential For Mars Life

Recommended Posts

http://www.aviationweek.com/aw/generic/sto...p;channel=space

The White House has been alerted by NASA about plans to make an announcement soon on major new Phoenix lander discoveries concerning the "potential for life" on Mars, scientists tell Aviation Week & Space Technology.

Sources say the new data do not indicate the discovery of existing or past life on Mars. Rather the data relate to habitability--the "potential" for Mars to support life--at the Phoenix arctic landing site, sources say.

The data are much more complex than results related NASA's July 31 announcement that Phoenix has confirmed the presence of water ice at the site.

International news media trumpeted the water ice confirmation, which was not a surprise to any of the Phoenix researchers. "They have discovered water on Mars for the third or fourth time," one senior Mars scientists joked about the hubbub around the water ice announcement.

The other data not discussed openly yet are far more "provocative," Phoenix officials say.

In fact, the Jet Propulsion Laboratory science team for the MECA wet-chemistry instrument that made the findings was kept out of a July 31 news conference at the University of Arizona Phoenix control center. The goal was to prevent them from being asked any questions that could reveal information before NASA is ready to make an announcement, sources say.

The Bush Administration's Presidential Science Advisor's office, however, has been briefed on the new information that NASA hopes to release as early as mid August. It is possible an announcement would not come until September, to allow for additional analysis. That will depend upon the latest results still being analyzed from the spacecraft's organic oven and soil chemistry laboratories.

Phoenix scientists have said from the start that neither the TEGA organic chemistry lab nor the MECA wet chemistry system could detect current or past life.

MECA's two microscopes do, however, have the resolution to detect bacteria--which would be life. Sources, however, say the microscopes have not detected bacteria.

The Phoenix scoop was successful in delivery of a soil/ice mixture to TEGA this week after the material stuck in the scoop on two tries. The analysis of that sample is under way. The sample contains about 1% ice and 99% soil.

As expected, the instrument immediately detected hydrogen and oxygen atoms indicating water. Its electricity load also increased initially, a positive sign that water ice was being melted by the system.

The fact TEGA is starting to process some ice samples "had champagne corks popping" here, says William Boynton TEGA principal investigator from the University of Arizona. "We have tasted the water and it tastes great," he said.

Before launch, some website literature by the TEGA team indicated it possibly could find organic evidence of "past" life. Both Boynton and Peter Smith, who heads the mission now, say that is not the case, although TEGA organic data could start major new arguments about life.

It has yet to find organics, but still has several sample ovens available to make such a discovery. An electrical short that earlier threatened TEGA operations has resolved itself, Boynton says.

News media cited the water ice finding as a major discovery, but it was totally expected by the science team. The different MECA data combined with TEGA is increasingly compelling as another piece in the puzzle of life.

The key is in the soil and water, and how the two behave together at that site on Mars, not the expected confirmation of water ice at this stage in the mission, Mars investigators told Aviation Week.

The MECA instrument, in its first of four wet chemistry runs a month ago, found soil chemistry that is "Earth-like" and capable of supporting life, researchers said then.

It is intriguing that MECA could have found anything more positive than that, but NASA and the University of Arizona are taking steps to prevent word from leaking out on the nature of the discovery made during MECA's second soil test, in which water from Earth was automatically stirred with Martian soil.

What have they found after confirming water ?

Petroleum? (biological)

"Petroleum, or oil, forms from the remains of plants and animals that lived in the ocean between 10 to 160 million years ago. When organisms died and sank to the bottom, they were covered in mud, sand, and other mineral deposits. This rapid burial prevented immediate decay, which would normally occur if organisms remained exposed on the sea floor.

The lack of oxygen in the sedimentary layers caused organisms to slowly decay into carbon-rich compounds. These compounds mixed with surrounding sediments and formed source rock, which is a type of fine-grained shale. As more layers were deposited on top of one another, pressure and heat acting on the source rock compressed the organic material into crude oil."

And according to the pope the aliens are coming.

Please google IRON MOUNTAIN.

...and watch the video.

you can see where all this is heading.

Downloaded it, took ages, but it wouldn`t stream without stopping, after all that I couldn`t watch because of all the religion.

It should come with a " contains god bothering " warning label

Is there life on Mars?

Yeah i just watched it, you have to ignore all the bible references.

Sadly my job involves bible references a lot (Deut. 23:15* and the like).

Try setting an entire index full of that stuff. Bleh!!

A laser instrument aboard the craft designed to gather information about how the planet's atmosphere and surface interact detected snow from clouds about 2.5 miles above where the lander touched down on the planet's northern plains.

Data sent back to Earth shows the snow turning into vapour before reaching the ground.

"Nothing like this view has ever been seen on Mars," said Jim Whiteway, lead scientist for Phoenix's meteorological station. "We'll be looking for signs that the snow may even reach the ground."

In addition, soil experiments conducted by the lander have provided the first evidence that water could once have been present at this arid, northerly latitude.

Tests by the lander's robotic laboratory revealed the presence of minerals that on Earth usually only form in the presence of liquid water- calcium carbonate, found in limestone and chalk, and particles thought to be clay.

Phoenix landed in the Martian arctic plains in May on a 90-day mission to probe the Red Planet's permafrost for "habitable zones" and evidence of organic compounds that could indicate an ability to support basic microbial life.

In July, mission researchers confirmed the long-held belief that frozen water was buried beneath the northern plains with proof that a hard subsurface layer at the lander's site contains water-ice. Tests meanwhile showed the soil was slightly alkaline and contained important nutrients and minerals.

Scientists believe there could once have been standing water at the arctic site or that the ice melted and interacted with the minerals.

"Is this a habitable zone on Mars? I think we're approaching that hypothesis," said the mission's lead scientist Peter Smith, of the University of Arizona. "We understand, though, that Mars has many surprises for us and we have not finished our investigation."

Phoenix has now been operating for nearly five months and on Monday Nasa extended the mission, saying the solar-powered lander would continue to operate until it dies amid the freezing, pitch black Martian winter.

At present the sun disappears for more than four hours every night and the output from the solar panels is decreasing. Scientists are racing to use the remaining four of Phoenix's eight tiny test ovens to analyse soil samples before the craft dies.

Experiments so far have failed to turn up definitive evidence of carbon-based compounds, considered the building blocks of life

Before the lander's power runs out, the Phoenix team will also attempt to activate a microphone on the craft to capture sounds on Mars.

I wonder why Mars Bars are called Mars?

From the Mars bar wikipedia page:

In 1932, Forrest Mars, estranged son of American candy maker Frank Mars, rented a factory in Slough and with a staff of twelve people began manufacturing a kind of chocolate bar that had not been seen before in the UK.

Dear Anorthosite- thank you for that- My ex girlfriend lived in Slough, and I missed my chance to go round the factory- maybe one day..
