Viking Results Revisited
Image from the Viking 2 lander site. Credit: NASA
Experiments prompted by a 2008 surprise result from NASA’s Phoenix Mars Lander suggest that soil examined by NASA’s Viking Mars landers in 1976 may have contained carbon-based chemical building blocks of life. The findings could make a difference in how astrobiologists search for signs of past or present life on the red planet. The only organic chemicals identified when the Viking landers heated samples of Martian soil were chlorine compounds interpreted as contaminants from cleaning fluids. But those chemicals are exactly what researchers found when adding perchlorate (the surprise finding from Phoenix) to desert soil from Chile.Source: [astrobio.net]

Drilling Down into Mars
NASA’s Phoenix lander revealed water ice mere inches beneath the martian surface, and chemical evidence from the landing site strongly hints that the region is habitable. But learning whether there is life in martian ice will require drilling — and drilling on Mars will be anything but easy.
As part of the IceBite Project, funded by NASA’s ASTEP program, a company in Brooklyn, NY, is designing and testing a series of drills to determine the optimum configuration for boring into subsurface martian ice.Source: [astrobio.net]

IceBite Blog: Learning to Respect the Weather
NASA’s IceBite project will spend three austral summers in Antarctica testing ice-penetrating drills for a future mission to Mars. A team of seven scientists is in Antarctica now for the first field season, installing scientific probes in the ice and frozen ground, and scouting for sites where the drills will be tested the following year. Team member, Margarita Marinova, is writing a blog of the team’s activities. In this first set of entries, she describes preparations for deployment to the field. In addition, readers can now send questions directly to the scientists as they explore Antarctica’s McMurdo Dry Valleys.

Taking a Bite of Antarctic Ice
University Valley, Antarctica.
Members of NASA’s IceBite team will spend the next six weeks studying the only place on Earth where the terrain resembles that of the Phoenix landing site on Mars. The place: a mile above sea level in Antarctica’s McMurdo Dry Valleys. The ultimate goal: to test ice-penetrating drills for a future mission to the martian polar north. Astrobio.net will be providing a direct link to scientists involved in the expedition, so now you can ask the scientists questions while they’re in the field.Source: [astrobio.net]

Phoenix Results Point to Climate Cycles
The first major peer-reviewed reports on the finding of NASA’s Phoenix Mars Mission have been published in the journal Science. The reports show how favorable chemistry and episodes of liquid water could have made the Phoenix landing site habitable for microbes in Mars’ past. In fact, it is possible that the site could become habitable again in Mars’ future according to Phoenix Principal Investigator, Peter Smith (ASU).Source: [astrobio.net]

A New Way to Keep Clean
It is almost impossible to get a spacecraft completely clean before launch. Therefore, missions to other planets carry some risk of forward contamination – where microorganisms from Earth travel along with the spacecraft to its destination. This is a big problem in the search for life on planets like Mars, because you don’t want to contaminate the site you’re going to be studying. To help combat this problem, a team of scientists funded by a NASA ASTEP award have developed a new cleaning protocol that could be used for future missions to Mars and beyond.

Water May Have Shaped Solar System's Tallest Mountain
Using computer modeling, researchers have determined that Mars’ Olympus Mons volcano – the tallest mountain in the solar system – may have formed on a bed of clay and sediments. The researchers believe that pockets of ancient water may still be trapped beneath the mountain, potentially creating an environment suitable for life.Source: [Astrobiology Magazine]

Carbonate Conundrum
NASA’s Phoenix lander mission is now over, and scientists are analyzing the data collected from its various experiments. Phoenix’s discovery of carbonates in the frozen northern soil of Mars indicates the area once could have had liquid water. However, there is no way to tell if the carbonates formed locally, or if they came from somewhere else on the planet and blew in with the wind.Source: [Astrobiology Magazine]

NASA Mars Lander Sees Falling Snow, Soil Data Suggest Liquid Past
NASA’s Phoenix Mars Lander has detected snow falling from Martian clouds. Spacecraft soil experiments also have provided evidence of past interaction between minerals and liquid water, processes that occur on Earth.
A laser instrument designed to gather knowledge of how the atmosphere and surface interact on Mars has detected snow from clouds about 4 kilometers (2.5 miles) above the spacecraft’s landing site. Data show the snow vaporizing before reaching the ground.
“Nothing like this view has ever been seen on Mars,” said Jim Whiteway, of York University, Toronto, lead scientist for the Canadian-supplied Meteorological Station on Phoenix. “We’ll be looking for...

Liquid Water in the Martian North? Maybe.
Perchlorate. Never heard of it? Join the club. But NASA’s Phoenix spacecraft has found it in the soil in the icy northern plains of Mars. And now that it’s been found, scientists are scrambling to explain how it got there, and what, if anything, its presence means about the habitability of the martian north.
Phoenix didn’t go to Mars to find perchlorate. It went looking for evidence of liquid water. From orbit, NASA’s Mars Odyssey in 2002 discovered water ice in the martian north, lying just inches beneath...

Phoenix Scrapes 'Almost Perfect' Icy Soil For Analysis
NASA’s Phoenix Mars Lander enlarged the “Snow White” trench and scraped up little piles of icy soil on Saturday, June 28, the 33rd Martian day, or sol, of the mission. Scientists say that the scrapings are ideal for the lander’s analytical instruments.
The robotic arm on Phoenix used the blade on its scoop to make 50 scrapes in the icy layer buried under subsurface soil. The robotic arm then heaped the scrapings into a few 10- to 20-cubic centimeter piles, or piles each containing between two and four teaspoonfuls. Scraping created a grid about...

Bright Chunks At Phoenix Lander's Mars Site Must Have Been Ice
Dice-size crumbs of bright material have vanished from inside a trench where they were photographed by NASA’s Phoenix Mars Lander four days ago, convincing scientists that the material was frozen water that vaporized after digging exposed it.
“It must be ice,” said Phoenix Principal Investigator Peter Smith of the University of Arizona, Tucson. “These little clumps completely disappearing over the course of a few days, that is perfect evidence that it’s ice. There had been some question whether the bright material was salt. Salt can’t do that.”
The chunks were left at the bottom of a trench informally called “Dodo-Goldilocks” when...

NASA's Phoenix Lander Has an Oven Full of Martian Soil
NASA’s Phoenix Mars Lander has filled its first oven with Martian soil.
“We have an oven full,” Phoenix co-investigator Bill Boynton of the University of Arizona, Tucson, said today. “It took 10 seconds to fill the oven. The ground moved.”
Boynton leads the Thermal and Evolved-Gas Analyzer instrument, or TEGA, for Phoenix. The instrument has eight separate tiny ovens to bake and sniff the soil to assess its volatile ingredients, such as water.
The lander’s Robotic Arm delivered a partial scoopful of clumpy soil from a trench informally called “Baby Bear” to the number 4 oven on TEGA last Friday,...

Rendezvous with Mars
NASA’s Phoenix lander is less than a week from touch down in the frozen northern wastes of Mars, where it will search for signs that, in the planet’s recent past, the region may have been habitable.
Phoenix is the first mission to target Mars’ northern polar region. NASA’s Mars Polar Lander (MPL), launched in 1999 toward the planet’s southern pole, crashed upon landing.
The two Vikings missions, Pathfinder, Opportunity and Spirit all landed “in the dry regions of the equatorial zone,” said Peter Smith, a research scientist at the University of Arizona in Tucson and principal investigator for the Phoenix mission....
