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 ...
Abstract submissions for the 2015 Astrobiology Science Conference (AbSciCon) have now closed. For details, visit the AbSciCon 2015 website at: http://www.hou.usra.edu/meetings/abscicon2015/
AbSciCon 2015 is the next in a series of conferences organized by researchers within the interdisciplinary field of astrobiology. Scientists from around the world will gather in Chicago, Illinois, from June 15-19, 2015, to report new research findings and plan for astrobiology’s future. The theme of AbSciCon 2015 is “Habitability, Habitable Worlds, and Life.”

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.

Due to its high iron content, the acidic Río Tinto river flows like red wine through a multicolored and rocky landscape. The Río Tinto has an average pH of 2.3, which is acidic enough to eat metal. Image credit: Leslie Mullen
Astrobiologists have outlined how geochemistry and metabolism are connected in subsurface microbial ecosystems beneath Spain’s Rio Tinto region. The Iberian Pyrite Belt (IPB) in the Río Tinto area is the largest known deposit of sulfide on Earth, and for decades it has been a field-site for scientists studying chemolithotrophic microbes.

Astrobiologists from the United States and Germany have recorded the highest level of UV radiation from the Sun yet known at the Earth’s surface.
You might expect the highest radiation levels of this type on Earth to be somewhere in Antarctica – underneath the hole in Earth’s ozone layer. This layer of Earth’s stratosphere contains higher concentrations of ozone gas (O3) than the rest of the atmosphere, and ...July 11, 2014 / Written by: Aaron Gronstal
Please join us in welcoming a new crop of early career astrobiologists into two of the many community-based programs supported by NASA Astrobiology: the 2014 International Summer School in Astrobiology and the NASA Astrobiology Early Career Collaboration Award.
This year’s theme for the 2014 International Summer School in Astrobiology is “Habitable Environments in the Universe.” The school will provide an interdisciplinary examination of the nature and evaluation of habitability, an environment’s ability to support life. The Astrobiology Early Career Collaboration Award offers research-related travel support for undergraduate, graduate students, postdoctoral fellows and junior scientists.
