NASA Open Data Turns Science Into Art
Guests enjoy Beyond the Light, a digital art experience featuring open NASA data, at ARTECHOUSE in Washington, D.C. on September 19, 2023. NASA/Wade Sisler An art display powered by NASA science data topped the Salesforce Tower in San Francisco, CA throughout December 2024. Nightly visitors enjoyed “Synchronicity,” a 20-minute-long video art piece by Greg Niemeyer, which used a year’s worth of open data from NASA satellites and other sources to bring the rhythms of the Bay Area to life.
Data for “Synchronicity” included atmospheric data from NASA and NOAA’s GOES (Geostationary Operational Environmental Satellites), vegetation health data from NASA’s Landsat program, and the Sun’s extreme ultraviolet wavelengths as captured by the NASA and ESA (European Space Agency) satellite SOHO (Solar and Heliospheric Observatory). Chelle Gentemann, the program scientist for the Office of the Chief Science Data Officer within NASA’s Science Mission Directorate, advised Niemeyer on incorporating data into the piece.

Greg Niemeyer’s “Synchronicity” was displayed on Salesforce Tower in San Francisco, CA, in December 2024. A recording of the piece on the tower’s display and the original animation are shown here. The video art piece was created using open NASA data, as well as buoy data from the National Oceanographic and Atmospheric Administration (NOAA). Greg Niemeyer/Emma Strebel “Artists have a lot to contribute to science,” Gentemann said. “Not only can they play a part in the actual scientific process, looking at things in a different way that will lead to new questions, but they’re also critical for getting more people involved in science.”
NASA’s history of engaging with artists goes back to the 1962 launch of the NASA Art Program, which partnered with artists in bringing the agency’s achievements to a broader audience and telling the story of NASA in a different and unexpected way. Artists such as Andy Warhol, Norman Rockwell, and Annie Leibovitz created works inspired by NASA missions. The Art Program was relaunched in September 2024 with a pair of murals evoking the awe of space exploration for the Artemis Generation.
The inaugural murals for the relaunched NASA Art Program appear side-by-side at 350 Hudson Street, Monday, Sept. 23, 2024, in New York City. The murals, titled “To the Moon, and Back,” were created by New York-based artist team Geraluz and WERC and use geometrical patterns to invite deeper reflection on the exploration, creativity, and connection with the cosmos. NASA/Joel Kowsky The use of NASA data in art pieces emerged a few decades after the NASA Art Program first launched. Several in-house agency programs, such as NASA’s Scientific Visualization Studio, create stunning animated works from science data. In the realm of audio, NASA’s Chandra X-ray Observatory runs the Universe of Sound project to convert astronomy data into “sonifications” for the public’s listening pleasure.
Collaborations with external artists help bring NASA data to an even broader audience. NASA’s commitment to open science – making it as easy as possible for the public to access science data – greatly reduces the obstacles for creatives looking to fuse their art with cutting-edge science.

NASA/Wade Sisler Another recent blend of NASA data and art came when digital art gallery ARTECHOUSE created “Beyond the Light,” a 26-minute immersive video experience featuring publicly available images from the James Webb Space Telescope and Hubble Space Telescope. The experience has been running at various ARTECHOUSE locations since September 2023. The massive potential for art to incorporate science data promises to fuel even more of these collaborations between NASA and artists in the future.
“One of the integral values of open science is providing opportunities for more people to participate in science,” Gentemann said. “I think that by getting the public interested in how this art is done, they also are starting to play with scientific data, maybe for the first time. In that way, art has the power to create new scientists.”

6 Min Read NASA Stennis Flashback: Learning About Rocket Engine Smoke for Safe Space Travel
An image shows engineers at an early version of the test stand at the Diagnostic Testbed Facility. From 1988 to the mid-1990s, NASA Stennis engineers operated the facility to conduct rocket engine plume exhaust diagnostics and learn more about the space shuttle main engine combustion process. Credits: NASA/Stennis NASA’s Stennis Space Center near Bay St. Louis, Mississippi, is widely known as the nation’s largest rocket propulsion test site. More than 35 years ago, it also served as a hands-on classroom for NASA engineers seeking to improve the efficiency of space shuttle main engines.
From 1988 to the mid-1990’s, NASA Stennis engineers operated a Diagnostic Test Facility to conduct rocket engine plume exhaust diagnostics and learn more about the space shuttle main engine combustion process. The effort also laid the groundwork for the frontline research-and-development testing conducted at the center today.
“The Diagnostic Test Facility work is just another example of the can-do, will-do attitude of the NASA Stennis team and of its willingness to support the nation’s space exploration program in all ways needed and possible,” said Joe Schuyler, director of the NASA Stennis Engineering and Test Directorate.

Envision a rocket or space vehicle launching into the sky. A trail of bright exhaust, known as the engine plume, follows. As metals wear down in the engines from the intense heat of the combustion process, the flame glows with colors, some visible, such as orange or yellow, and others undetectable by the human eye.
The colors tell a story – about the health and operation of the engine and its components. For space shuttle main engines, which flew on multiple missions, engineers needed to understand that story, much as a doctor needs to understand the condition of a human body during checkup, to ensure future engine operation.
Where better place to study such details than the nation’s premier propulsion test site? Paging NASA Stennis.

NASA Stennis has long enabled and supported innovative and collaborative work to benefit both the agency and the commercial space industry. When NASA came calling in the late 1980s, site engineers went to work on a plan to study space shuttle main engine rocket exhaust.
The concept for an enabling structure about the size of a home garage was born in October 1987. Five months later, construction began on a Diagnostic Testbed Facility to provide quality research capabilities for studying rocket engine exhaust and learning more about the metals burned off during hot fire.
The completed facility featured a 1,300-square-foot control and data analysis center, as well as a rooftop observation deck. Small-scale infrastructure was located nearby for testing a 1,000-pound-thrust rocket engine that simulated the larger space shuttle main engine. The 1K engine measured about 2 feet in length and six inches in diameter. Using a small-scale engine allowed for greater flexibility and involved less cost than testing the much-larger space shuttle engine.
An image shows Sverdrup Technology’s Robert Norfleet as he preps the dopant injection system for testing at the Diagnostic Testbed Facility. The goal of the facility was to inject known metals and materials in a chemical form and then look at what emissions were given off. During one test, generally a six or 12 second test, operators would inject three known dopants, or substances, and then run distilled water between each test to clean out the system.NASA/Stennis An image shows engineers Stan Gill, Robert Norfleet, and Elizabeth Valenti in the Diagnostic Testbed Facility test control center. NASA/Stennis The Process
Engineers could quickly conduct multiple short-duration hot fires using the smaller engine. A six-second test provided ample time to collect data from engine exhaust that reached as high as 3,900 degrees Fahrenheit.
Chemical solutions simulating engine materials were injected into the engine combustion chamber for each hot fire. The exhaust plume then was analyzed using a remote camera, spectrometer, and microcomputers to determine what colors certain metals and elements emit when burning.
Each material produced a unique profile. By matching the profiles to the exhaust of space shuttle main engine tests conducted at NASA Stennis, determinations could be made about which engine components were undergoing wear and what maintenance was needed.
We learned about purging, ignition, handling propellants, high-pressure gases, and all the components you had to have to make it work…It was a very good learning experience.

NASA Stennis Engineer
The Benefits
The Diagnostic Testbed Facility played a critical safety role for engine operations and also provided a real-time opportunity for NASA Stennis engineers to learn about exhaust diagnostics.
Multiple tests were conducted. The average turnaround time between hot fires was 18 to 20 minutes with the best turnaround from one test to another taking just 12 minutes. By January 1991, the facility had recorded a total of 588 firings for a cumulative 3,452 seconds.
As testing progressed, the facility team evolved into a collection of experts in plume diagnostics. Longtime NASA Stennis engineer Glenn Varner serves as the mechanical operations engineer at the Thad Cochran Test Stand, where he contributed to the successful testing of the first SLS (Space Launch System) core stage onsite.
However, much of Varner’s hands-on experience came at the Diagnostic Test Facility. “We learned about purging, ignition, handling propellants, high-pressure gases, and all the components you had to have to make it work,” he said. “It was a very good learning experience.”

The Impact
The Diagnostic Testbed Facility impacted more than just those engineers involved in the testing. Following the initial research effort, the facility underwent modifications in January 1993. Two months later, facility operators completed a successful series of tests on a small-scale liquid hydrogen turbopump for a California-based aerospace company.
The project marked an early collaboration between the center and a commercial company and helped pave the way for the continued success of the NASA Stennis E Test Complex. Building on Diagnostic Testbed Facility knowledge and equipment, the NASA Stennis complex now supports multiple commercial aerospace projects with its versatile infrastructure and team of propulsion test experts.
“The physical remnants of the Diagnostic Testbed Facility are barely recognizable now,” Schuyler said. “But that spirit and approach embodied by that effort and its teams continues in force at the center.”
Additional Information
NASA Stennis has leveraged hardware and expertise from the Diagnostic Testbed Facility to provide benefit to NASA and industry for two decades and counting.
The facility’s thruster, run tanks, valves, regulators and instrumentation were used in developing the versatile four-stand E Test Complex at NASA Stennis that includes 12 active test cell positions capable of various component, engine, and stage test activities.
“The Diagnostic Testbed Facility was the precursor to that,” said NASA engineer Glenn Varner. “Everything but the structure still in the grass moved to the E-1 Test Stand, Cell 3. Plume diagnostics was part of the first testing there.”
When plume diagnostic testing concluded at E-1, equipment moved to the E-3 Test Stand, where the same rocket engine used for the Diagnostic Testbed Facility has since performed many test projects.
The Diagnostic Testbed Facility thruster also has been used for various projects at E-3, most recently in a project for the exploration upper stage being built for use on future Artemis missions.
In addition to hardware, engineers who worked at the Diagnostic Testbed Facility also moved on to support E Test Complex projects. There, they helped new NASA engineers learn how to handle gaseous hydrogen and liquid hydrogen propellants. Engineers learned about purging, ignition, and handling propellants and all the components needed for a successful test.
“From an engineering perspective, the more knowledge you have of the processes and procedures to make propulsion work, the better off you are,” Varner said. “It applied then and still applies today. The Diagnostic Testbed Facility contributed to the future development of NASA Stennis infrastructure and expertise.”
