Astrobiologists studying ecological changes in shallow lakes on the North Slope of Alaska have discovered diverse sources of methane in lake sediments. The study shows that methane can arise from sources deep in the Earth or from biological communities that inhabit sediments on the lake floor.
Importantly, the research also reveals that rising global temperatures may result in increasing production of this potential greenhouse gas by methane-generating microbes. The results of the five-year study are an important ...April 7, 2015 / Posted by: Aaron Gronstal

A new study is helping astrobiologists understand whether or not the decomposition of oxalic acid could act as a source of C-O-H in petrologic experiments. The team studied how oxalic acid decomposes in oxidizing, reducing and unbuffered solutions at temperatures up to 800 °C.
The paper, “In-situ characterization of oxalic acid breakdown at elevated P and T: Implications for organic C-O-H fluid sources ...April 3, 2015 / Written by: Aaron Gronstal

Researchers supported by the Astrobiology Science & Technology for Exploring Planets (ASTEP) element of the Astrobiology Program have published a field report on the Planetary Lake Lander (PLL) probe. The report describes the design and operation of the PLL as well as its ground data systems.
The PLL is designed to study physical, chemical, and biological processes in a high-altitude lake, and how these processes are being affected by deglaciation. The PLL also provides an opportunity to test technologies that could be used on a future mission to Saturn’s moon Titan.
Check out the Planetary Lake Lander Project Video Series here.
The study, “Planetary Lake Lander—A Robotic Sentinel to Monitor Remote Lakes,” was published in the Journal of Field Robotics.

On the radio program Big Picture Science, David Grinspoon recently joined a discussion about the impacts of humankind on planet Earth. Right now, the Earth is in a geological epoch known as the Holocene. However, some scientists believe we have moved into a new epoch dubbed the 'Anthropocene,’ or the age of man.

Baruch S. “Barry” Blumberg, recipient of the 1976 Nobel Prize in Physiology or Medicine, was the founding director of the NASA Astrobiology Institute (NAI). When Blumberg passed away suddenly of a heart attack at age 85 on April 5, 2011, it was a huge loss for the astrobiology community.
This month, the journal Astrobiology features a tribute to Barry Blumberg written by current NAI Director, Carl Piltcher. The article is freely available on the journal’s website, and provides a background of Blumberg’s remarkable life ...January 9, 2015 / Written by: Aaron Gronstal

A careful study of images taken by the NASA rover Curiosity has revealed intriguing similarities between ancient sedimentary rocks on Mars and structures shaped by microbes on Earth. The findings suggest, but do not prove, that life may have existed earlier on the Red Planet. The photos were taken as Curiosity drove through the Gillespie Lake outcrop in Yellowknife Bay.
The study was supported ...

Curiosity celebrated two years on Mars on August 5, 2014, and is continuing its progress across the surface of the planet. In a tweet on September 2, 2014, Curiosity shared its view of the path ahead and proclaimed, “Head for the hills! I’m driving towards these hills on Mars to do geology work & also search for clouds.”
In this news post from astrobio.net, Dr. Robert M. Haberle, Planetary Scientist at NASA Ames and a team member for the Rover Environmental Monitoring Station (REMS), explains why clouds on Mars are relevant to Curiosity’s astrobiology goals.Curiosity tweeted this image from the surface of Mars on Sept 2, 2014.

REMS is an environmental monitoring station and was contributed to the Mars Science Laboratory (MSL) mission by the Centro de Astrobiologia (CAB) in Spain, one of the NASA Astrobiology Institute’s international partners.
