Astrobiology at Goddard Space Flight Center

Astrobiology at GSFC stretches across all four of the divisions in the Science and Exploration Directorate: Earth, Astrophysics, Heliophysics, and Planetary Science. This is one of the strengths of Goddard, as it approaches this interdisciplinary endeavor with the full breadth of NASA science expertise.

GSFC personnel are involved at just about every level of every major astrobiology endeavor, from the incorporation of astrobiology into spaceflight missions and instrumentation, to the leadership of agency-level astrobiology initiatives, to leadership in international astrobiology organizations, to leadership of and participation in multiple successful peer-reviewed awards for research projects large and small.

GSFC has numerous groups, laboratories, and individuals conducting astrobiology research. Numerous opportunities for post-doctoral fellowships and some for internships exist.

Missions & Flight Instruments

A number of missions and flight instruments have a strong astrobiology component and are GSFC-led or have significant GSFC participation. Explore some of these missions and instruments below.

In Operation

Hubble Space Telescope
The Hubble Space Telescope (HST), managed by GSFC, makes observations to provide clues about how planets form from dust and debris around stars, search for exoplanets, and observe bodies within the Solar System to investigate life’s potential in the Solar System.

MAVEN
The Mars Atmosphere and Volatile EvolutioN (MAVEN) mission, managed by GSFC, explores Mars’ upper atmosphere, ionosphere and interactions with the sun and solar wind. An important aspect of the MAVEN mission is studying early Mars' atmospheric loss, which may have been partially responsible for its transition from a planet capable of supporting liquid surface water to the dry, desert world we know today.

OSIRIS-REx
The Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx), managed by GSFC, will return a sample from the near-Earth asteroid Bennu. Bennu is a carbon-rich asteroid that records the earliest history of our Solar System which may contain the molecular precursors to the origin of life and the Earth’s oceans.

TESS
The Transiting Exoplanet Survey Satellite (TESS), managed by GSFC, identifies and characterizes planets ranging from Earth-sized to gas giants, orbiting a wide range of stellar types and orbital distances. Characterizing the atmospheres of small planets is a key step in determining the potential habitability of extrasolar worlds that orbit distant stars.

Curiosity
Curiosity is focused on determining the past habitability of Mars. The Sample Analysis at Mars (SAM) instrument is supplied by GSFC performs chemical analysis of minerals, gases, and organic compounds on Mars.

ExoMars Trace Gas Orbiter
The ESA ExoMars Trace Gas Orbiter (TGO) mission’s United States data center is managed at GSFC. TGO is orbiting Mars with the purpose of searching for trace gases-- methane, hydrocarbons, and their isotopes--important for astrobiology.

In Development

James Webb
The James Webb Space Telescope (JWST), managed by GSFC, will make observations on the composition of fait object in the Solar System and study the formation and evolution of habitable worlds, to improve our understanding processes that have shaped habitability in the Solar System.

Roman Space Telescope
The Nancy Grace Roman Space Telescope, managed by GSFC, will make observations that could contribute to the discovery of new worlds beyond our solar system and advance the search for extrasolar planets that could be suitable for life.

ExoMars
The ESA Rosalind Franklin ExoMars Rover has a GSFC supplied component which will study organic compounds from the subsurface of Mars.

Dragonfly
Dragonfly is co-led by a GSFC Deputy PI with GSFC supplied science instruments and components will explore diverse locations to characterize the habitability of Titan’s environment, to investigate how far prebiotic chemistry has progressed.

Mars Sample Return
The Mars Sample Return campaign contains the Capture/Containment and Return System, managed by GSFC, which will return samples from the surface of Mars for study on Earth to search for evidence of past or present life.

Comet Interceptor
The ESA Comet Interceptor missions, with the US Co-PI at GSFC, consists of 3 spacecraft working together to perform the first close encounter to a long period comet in 2028-2032. One spacecraft will make remote observations of the comet from afar, while two other spacecraft will venture closer to the target with complementary instrument payloads.

Nexus for Exoplanet System Science
The goals of NExSS are to investigate the diversity of exoplanets and to learn how their history, geology, and climate interact to create the conditions for life. NExSS will accelerate the discovery and characterization of other potentially life-bearing worlds in the galaxy, using a systems science approach.

Network for Ocean Worlds
NASA has formed the Network for Ocean Worlds (NOW) to advance comparative studies to characterize Earth and other ocean worlds across their interiors, oceans, and cryospheres; to investigate their habitability; to search for biosignatures; and to understand life—in relevant ocean world analogues and beyond.

Research Consortia

Goddard Center for Astrobiology (GCA)

GCA, a member of PCE3, uses a combination of laboratory experiments, observations, and models to investigate returned samples and to enable us to learn about abiotic organic chemical evolution and guide the search for biosignatures.

Principal Investigator

Laboratory for Agnostic Biosignatures (LAB)

LAB, a member of NFoLD, focuses on four features of life that do not presuppose a specific biochemistry, using these concepts to begin to build a framework for looking for life “as we don’t know it.” These features include patterns of surface complexity, elemental accumulation, and evidence of energy transfer.
