Who We Are.

The Science Directorate at NASA’s Langley Research Center provides essential science leadership to NASA with decades of intellectual expertise in the areas of Atmospheric Composition, Air Quality, Earth’s Energy Budget and Lidar Remote Sensing that supports Earth science, planetary science and heliophysics.

Langley has built a capability in suborbital and ground-based research that has been in high demand since the Science Directorate’s initiation in the late 1960s.

SD Flight Projects enable ground-breaking science through spaceflight platforms with a 100% instrument success rate for on-orbit operations.

What We Do.

We are committed to delivering science that is balanced between Research & Analysis, technology development, airborne science and flight development.​

We study atmospheres using active and passive remote sensing and in-situ measurements. Through our ground and flight hardware development, we infuse technology and gather science observations that produce knowledge, information and insight that informs policy and serves society. We create essential, global data records utilized by the international science community. 

We provide and maintain capabilities to ensure effective and affordable delivery of that knowledge.

2021 Earth Science Highlights
  • We delivered a key part of the CLARREO Pathfinder payload, the Power Converter Unit (PCU), to the Laboratory for Atmospheric and Space Physics (LASP) in Boulder, CO. We designed, built, and tested the PCU, which will serve as the power interface between CPF and the ISS, ensuring that the right level of power is delivered to the CLARREO Pathfinder payload. CLARREO Pathfinder will launch to the ISS in late 2023, where it will take measurements to help us better understand Earth’s changing climate. + Learn More

2021 Applied Sciences Highlights
  • In 2021, with the support of the U.S. Department of State, DEVELOP continued its contribution to NASA’s multiyear effort to strengthen STEM foundations in Bhutan. The effort, titled “Advancing Science, Technology, Engineering, and Math in Bhutan through Increased Earth Observation Capacity,” saw DEVELOP conduct five projects in 2021 that provided 21 opportunities for Bhutanese scholars to build analytical skills through the use of NASA Earth observations, as well as supported their professional development. These projects explored how satellite data could be applied to conservation, forest management, and crop monitoring.


An interdisciplinary team of educators, scientists, technology experts and communication specialists collaborate with the education community to bring authentic Earth science practices and real-world data into the classroom.

Goddard Award in Outreach for exceptional innovation reaching families and the public at home during the COVID-19 pandemic. The award was given to team members and scientists involved in the GLOBE (Global Learning and Observations to benefit the Environment Program) Program's GLOBE Observer app. The app allows citizen scientists to submit observations that benefit scientists who study different facets of Earth's environment, including clouds, mosquito habitats, land cover and trees. GLOBE Observer Clouds, which ran a community cloud challenge in 2020, is led out of Langley. Winners from Langley are Kristopher Bedka, Brant Dodson, Tina Harte, Ali Omar, Angela Rizzi, Tina Rogerson, Jessica Taylor, Patrick Taylor and Marilé Colón Robles. + Learn More
Beyond Earth

Our atmospheric research also contributes to planetary science, heliophysics & astrophysics through the design, development, modeling and simulation of Entry, Descent and Landing (EDL) systems for Earth and planetary bodies, and also through our research on space weather and atmospheres of Terrestrial Type Exoplanets and planets.

2021 Beyond Earth Highlights
  • The critical issues of long-term change in the geospace environment evident in the SABER data were highlighted in this article, “An Observational Gap at the Edge of Space", that appeared in Eos, the periodical of the American Geophysical Union as the issue cover story and the lead discussion topic in the Editor’s introduction. The article also calls attention to the looming gap in satellite observations of the geospace environment and the need for continued observations to understand the extent and consequences of the long-term cooling of the upper atmosphere. Coincidentally, this issue also discusses a new type of aurora, known as the ‘dune’ aurora. SABER contributed to the analysis of the cause of these aurorae with the in a publication titled, “Large-Scale Dune Aurora Event Investigation Combining Citizen Scientists' Photographs and Spacecraft Observations.”

Air Quality Highlights

At any given time, there is a fire burning somewhere on Earth. NASA Langley’s Dr. Amber Soja joined NASA experts to take a closer look at how fires are part of our changing planet during a NASA ScienceLive episode titled, “A World of Fires.” As the climate warms, it has directly affected the way fires occur, with longer fire seasons and more extreme fires that are harder to suppress. With a fleet of satellites orbiting Earth, NASA has a unique perspective to keep an eye on these fires, the impact they have on ecosystems, and how smoke degrades air quality for local communities and populations downwind from biomass burning.

Watch: NASA Science Live: A World of Fires

A joint campaign led by NASA and the National Oceanic and Atmospheric Administration (NOAA), Fire Influence on Regional to Global Environments and Air Quality (FIREX-AQ) is targeting broad questions about the chemical and physical properties of fire smoke, how it is measured and how it changes from the moment of combustion to its final fate hundreds or thousands of miles downwind. All of these have implications for public health. In 2019, NASA Langley contributed mission science leadership. The NASA Langley National Airborne Sounder Testbed - Interferometer (NAST-I) sensor was included as part of the aircraft payload for the ER-2 component. On the ground, the NASA Langley Aerosol Research Group Experiment (LARGE) operated a van full of instruments to catch the smoke as it settled.

Most of us don’t think twice about breathing. In fact, the average adult takes around 20,000 breaths per day. Understanding the air we breathe is essential to life on Earth. In 2019, NASA Langley’s Dr. Patrick Taylor and Dr. Jim Crawford were interviewed for a Health Journal article titled, “The Air Out There: Understanding Air Pollution.”

For the past four years an international research team sponsored by NASA and the Indian Space Research Organization (ISRO) has been studying the Asian Tropopause Aerosol Layer (ATAL), an area of enhanced aerosol particles that appears in the summertime. Using balloon-lofted instruments, the Balloon measurement campaign of the Asian Tropopause Aerosol Layer (BATAL) has collected data to better understand this seasonal atmospheric phenomenon and its potential impact on water resources, ozone, weather and climate. In 2019, the team collected data on trace gases and the properties of aerosols and ice crystals. NASA Langley Research Center scientists deployed to India to understand how pollution in Asia is transported into the stratosphere during the active summer monsoon, an annual phenomenon that brings humid weather and torrential rainfall to India and Southeast Asia.
