    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 ...

    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.

    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 ...

  1. 2014 NASA Astrobiology MIRS Fellows


    Please join us in welcoming four new fellows to the NASA Astrobiology Minority Institution Research Support (MIRS) Program!

    The goal of the NAI MIRS Program is to help train a new generation of researchers in astrobiology and to increase diversity within the astrobiology community. Over the past ten years, the program has provided opportunities for faculty members and students from minority-serving institutions to partner with astrobiology investigators.

    One of the program’s main objectives is to engage more faculty from under-represented schools in astrobiology research and increase the number of students pursuing careers in astrobiology.

    The four newest MIRS partnerships ...

    In 2011, Jennifer Glass joined a scientific cruise to study a methane seep off of Oregon’s coast. In these cold, dark depths, microbes buried in the sediment feast on methane that seeps through the seafloor.

    A product of their metabolism, bicarbonate, reacts with calcium in seawater to form tall rocky deposits. The chemical energy these organisms extract from methane supports a vibrant underworld — an eclectic blanket of microbial mats, clam fields and tube worms.

    “It’s such a beautiful landscape,” says Glass, an alumnus of NASA’s Astrobiology post-doctoral ...

    Scientists supported by the Astrobiology Technology for Exploring Planets (ASTEP) and Astrobiology Instrument Development Programs (ASTID) have outlined the proposed 'Icebreaker’ mission to Mars in a recent paper in the Journal of Field Robotics.

    Icebreaker would send a robotic lander to the same region of Mars visited by the Phoenix mission in 2007. After landing at Mars’ polar latitudes, Icebreaker would use its tools to penetrate the surface and excavate samples. The goal is to see what is hiding beneath the ice caps, and whether or not Icebreaker ...
