Marikh (Mars) : Misi, Eksplorasi & Penemuan

ibnur

Saya pun ader soalan. Kenapa Al-Quran tidak boleh dikatakan makhluk walaupun Al-Quran itu sendiri dari Allah (hence, in my understanding, still a creation of Allah)?

Ini fahaman muktazilah.

cuba search al-quran + makhluk + muktazilah ...

yaminz

Yup, rasa nyer benda nei da dsanggah dulu... Para ulama skrg mgatakan Al-Qur'an bukan makhluk sbab nyer, Al-Qur'an tidak mmiliki ciri2 yg bole danggap sbgi makhluk... Al-Qur'an adalah kalammullah...

yaminz

Walaupon Al-Qur'an tu ciptaan Allah, tp xsmesti nyer Al-Qur'an tu adalah makhluk... Stiap ciptaan Allah, tdiri bgai2 jenis tidak kira makhluk dan bukan makhluk dan jgn anggap Allah hanya cipta makhluk... Contoh nyer, Syurga adalah ciptaan Allah tp bukan makhluk...

December 21st 2012, tarikh terakhir calendar Mayan....aku pun tak sure ape akan jadi pastu, or pad hari tersebut, some says that planets will change their course, some says that something will happen, tatau la yg baek atau burok, hopefully yg baek sebab aku nak idop lagik sehhh, hahah

kesian Mars, stand the chance untuk asteroid impact....bahaye tuh

tapi december 21st 2012 ni maseh menghantui aku, sbb ade scientific agenda di sebalek tarikh tu, i've heard about Apophis...scary sak....

kalau btol jadi mende tu, hopefully bukan kiamat la....apophis akan hentam straight masuk laut pasific utara slightly atas Jepun, near the Bearing Sea, pastu cam biasa la.......mega tsunami 1-2 batu tinggi, sudden earthquakes, massive firestorm, n cemacam agi....aku rase singapore hancor sekelip mata je, huhu...mampos aku! wahrhrhrhhr

p/s God still love us.........amin!

oh baru teringat, yg kuta belajaq all those carbon cycles, nitrogen cycles, etc..hmmm...true true it makes perfect sense now as to why the planet itself must be alive. But Mars contains Co2 anyway though, same as what we called as the planet of greenhouse effect. It 's quite close to the sun

haiiiiiiiiiiiiiiiii..long time no see.. you ..miss you..


okay yep mmg mars ade banyak unsur ferum- ferum (II) ? ferum ( III) oxide?

The scoop on Phoenix Mars Lander's robotic arm carries Martian soil for sampling, with one of the lander's solar arrays in the foreground. This image was taken June 10 by Phoenix's Surface Stereo Imager

NASA's Phoenix Mars Lander got its first (very) close-up look at Martian soil, scientists said Friday.

Phoenix used its robotic arm scoop to deliver a sample of the soil around the landing site to its optical microscope, which can zoom in on soil particles as small as 2 microns across (the size of some bacteria) — the smallest scale ever seen on Mars.

"This is the highest resolution image of the soil of Mars," said the mission's geology team leader, Tom Pike of University College London. "This is the first time we've reached down to this level."


The microscope images show a wide variety of particle sizes, colors and types in the soil. One of the particles viewed through the microscope is just 50 microns across, a little less than diameter of human hair. It is greenish in one part, which Pike says could be olivine, a mineral seen elsewhere on Mars. The other part of the particles "the very characteristic orange color" of the Martian soil as a whole, Pike said.

Another particle is black, glassy and more rounded in its shape. "This may very well be a volcanic glass," Pike said.

The microscope images also showed that the clumpy tendencies of the soil go right down to the microscopic level. The green-and-orange particle is actually "a clump of even finer particles," Pike said.

"It's obviously a very sticky material right down to the finest scale," he added.

The tendency of the soil particles to stick together has caused some problems for the mission. When the first soil sample was delivered to the Thermal and Evolved-Gas Analyzer (TEGA) on June 6, it got stuck behind the screened entrance to the instrument. After using a vibrator on the machine, the soil eventually loosened and fell into TEGA. Results from TEGA's first analysis should be sent back to mission scientists next week.

To get around the clumping problem, scientists are now using a "sprinkle" technique to deliver samples. The scoop on the robotic arm is tilted forward, and then a rasp at the end (designed for scraping up hard ice) is run to dribble the soil into the instrument, like a salt shaker. This was the technique used to deliver the sample to the microscope.

Phoenix's microscope hasn't been the only busy instrument aboard the lander. The craft's stereoscopic imager has continued taking high-resolution, color images of the area around the landing site (these will eventually be stitched together into a 360-degree panorama).

The robotic arm continued digging into its first two trenches, Dodo and Baby Bear, revealing more of the unidentified white material seen under the surface layer of regolith. Mission scientists are still debating whether the white material is ice, or a layer of salt minerals that could have formed above the ice layer.

To find out what the material is, "we need to gather a sample of it and put it in our instruments," said Phoenix principal investigator Peter Smith of the University of Arizona. "We have just the right instruments on the surface here to answer those questions."

Phoenix lander confirms presence of ice on Mars




Exhaust from the lander's descent engine revealed a patch
of ice or rock beneath the Mars dirt.


May 25: A portion of the Martian landscape as seen from the
Phoenix Mars Lander after it landed on the Red Planet.

Sharp new images received Saturday from the Phoenix lander largely convinced scientists that the spacecraft's thrusters had uncovered a large patch of ice just below the Martian surface, team members said.


Scientists rejoiced after the Phoenix Mars lander confirmed their long-held belief that ice is hiding under the surface in the Red Planet's northern region.

When the lander took new photographs of the trench four days later on Thursday, the material had vanished, settling the debate about whether it was salt or ice.

Scientists at the Jet Propulsion Laboratory in Pasadena, California concluded that the material was frozen water that evaporated when exposed to the sun. Salt would not have reacted that way, scientists said.

"We found what we were looking for," Phoenix science team member Mark Lemmon said in a news conference. "We came to this site because we were expected to find water ice."

Scientists believed that a vast sheet of ice was hiding in the planet's North pole after NASA's Mars Odyssey surveyed it in 2002.

"If you had a big broom and swept this area off, we are on an icesheet," said Phoenix Principal Investigator Peter Smith of the University of Arizona, Tucson.

"We have found the proof that we have been seeking that showed that this bright material really is water ice, and not another substance," Smith said.

"Now we know for sure that we are on an icy surface and we can really meet the science goal of our mission at the highest level," he said.

Besides evidence of water, the three-month Phoenix mission is also hoping to find life-supporting organic minerals in the polar region.

The probe is equipped with oven-like instruments that can melt any ice collected by the robotic arm and analyze the water.

The trick, Smith said, is for Phoenix to move ice samples fast enough from the ground into one of the lander's eight ovens within 30 minutes before it evaporates in the atmosphere.

"Just the fact that there's ice there doesn't tell you if it's habitable," he said.

"With ice and no food it's not a habitable zone. We don't eat rocks. We have to have carbon chain materials that we ingest into our bodies to create new cells and give us energy. That's what we eat and that's what has to be there if you're going to have a habitable zone on Mars."

Water filtered down on Mars may have left its mark on surrounding minerals, and impurities in the ice could tell a great deal about the climactic history of this region of the planet.

Mars is currently too cold for liquid water but it is possible that in some distant past the polar regions were warmer, scientists posit.

Water is a main ingredient for life and the polar region at some point may have been habitable: that is a puzzle Phoenix is exploring.

Phoenix's robotic arm made contact in another trench Thursday with a hard surface scientists believe could be an icy layer.

"We have dug a trench and uncovered a hard layer at the same depth as the ice layer in our other trench," said Ray Arvidson of Washington University in St. Louis, co-investigator for the robotic arm.

After trying to crack further into it, the arm became immobilized, which is the expected programmed reaction for when it hits a hard surface.

possible ice. cuz mars is much  colder than earth..
but then no food and no sign of habitable area...

cluesan

its not about habitable area, but scientist wants at least finding an alien micro organism.

dexa

not sure even whether they gonna find those, clue..
when we cant even send a human to seek for it -

NASA spacecraft finds ice on Mars
By Dan Whitcomb

LOS ANGELES (Reuters) - The Mars Phoenix Lander has found ice on the surface of the Red Planet, triumphant NASA scientists said on Thursday, a key discovery for the spacecraft as it searches for water and signs of life on Earth's closet planetary neighbour.

The proof came in a series of pictures sent back by Phoenix of a trench it dug with its robotic arm at the arctic circle of Mars, showing dice-sized chunks of white material that are seen to melt away over the course of several days.

"It is with great pride and a lot of joy today that I announce we've found the proof we've been seeking that this really is water ice and not some other material," mission principal investigator Peter Smith, of the University of Arizona, said at a press conference.

The presence of water on Mars is crucial because it is a key to the question of whether life, even in the form of mere microbes, exists or has ever existed on Mars. On Earth, water is a necessary ingredient for life.

Scientists first discovered what they believed was a vast sheet of ice under the barren surface of the Martian north pole in 2002, when the Mars Odyssey Orbiter detected it through a hydrogen analysis while circling the planet.

Phoenix landed on May 25 and uncovered the white chunks when it dug a trench a few inches into the soil but NASA was at first cautious in pronouncing it ice because of the possibility that it could be salt.

'NO ARGUMENT'

But the sequence of photographs showed about eight dice-sized chunks slowly vanishing, confirming for the scientific team at about noon PDT (1900 GMT) on Thursday that it was water ice.

"It was just so incredibly convincing," Smith said of seeing the images for the first time. "There was no argument to be made anymore and we all just kind of applauded."

Though the scientists pronounced themselves "thrilled" with the discovery, it is only the first step in the primary mission of Phoenix to determine whether water has flowed on Mars and if life exists on the planet at any level.

"Now we know for sure that we are on an icy surface and can really meet the science goals our mission," Smith said. "I am just sitting on the edge of my chair, really, waiting to find out what (our instruments) can tell us."

Over the next several weeks the science team will analyze the ice and soil to determine its geologic history and look for organic material.

"The fact that there's ice there doesn't tell you anything about whether it抯 habitable," Smith said. "The ice may be always in a frozen state and with ice in a frozen state and no food, thats not a habitable zone.

"It抯 really the modern history of these plains we're here to unravel," he said.

The $420 million lander spent 10 months journeying from Earth to Mars and has already analyzed soil samples scraped from the surface and put into its onboard laboratory.

The Mars Lander’s mission on the fourth planet from the Sun is a dream come true for many scientists who have been trying for decades to prove that there is indeed water on Mars, and that where there’s water, there could be life.

NASA’s Phoenix lander recently discovered chunks of bright materials near the surface of the planet, which at a first glance appeared to be ice. Mission investigators were convinced: could it be anything else?

At the time, the answer would have been yes, as some feared those could have been in fact salt deposits. However, their complete disappearance in just days after they had been uncovered made it clear: it was water ice, as scientists confirmed last week.

Phoenix Principal Investigator Peter Smith of the University of Arizona, Tucson explained that their disappearance was a confirmation that the images sent by the Mars Lander depicted ice: “salt can’t do that.”

The phenomenon couldn’t be clearer, and sublimation (the transition from a solid phase to a gas phase with no intermediate liquid phase) is the key word here: scientists explained that the chunks of ice evaporated after coming in direct contact with the Martian atmosphere.

As Phoenix’s robotic arm continues its digging, preparing us for a possible encounter with another icy layer, the science team in charge of the mission has a lot to do. Finding water (in solid phase) on Mars is just one of the elements that could answer the big question: has life on Mars ever been possible?

With the help of the instruments onboard, scientists will try to establish through detailed analysis whether the environment below the surface of the planet is or has even been favorable to microbial life.

So far, Phoenix’s Mars mission gave hope to scientists and enthusiasts likewise in their mission to discover life somewhere in the Solar System.

The key evidence brought to light in the first month of the lander’s mission is a sign that Phoenix is on the right track, and that what some reject as pure wishful thinking could be in fact as close to reality as it gets: we’ve got water, let’s find life!
