NASA Stennis Releases First Open-Source Software

Editor’s Note: The following is one of three related articles about the NASA Data Acquisition System and related efforts. Please visit Stennis News – NASA to access accompanying articles.

NASA’s Stennis Space Center near Bay St. Louis, Mississippi, has released its first-ever open-source software, a peer review tool to facilitate more efficient and collaborative creation of systems applications, such as those used in its frontline government and commercial propulsion test work.

“Everyone knows NASA Stennis as the nation’s premier rocket propulsion test site,” said David Carver, acting chief of the Office of Test Data and Information Management. “We also are engaged in a range of key technology efforts. This latest open-source tool is an exciting example of that work, and one we anticipate will have a positive and widespread impact.”

The new NASA Data Acquisition System Peer Review Tool was developed over several years, built on lessons learned as site developers and engineers created software tools for use across the center’s sprawling test complex. It is designed to simplify and amplify the collaborative review process, allowing developers to build better and more effective software applications.

The new NASA Stennis Peer Review tool was developed using the same software processes that built NDAS. As center engineers and developers created software to monitor and analyze data from rocket propulsion tests, they collaborated with peers to optimize system efficiency. What began as an internal review process ultimately evolved into the open-source code now available to the public.

“We refined it (the peer review tool) over a period of time, and it has improved our process significantly,” said Brandon Carver (no relation), a NASA Stennis software engineer. “In early efforts, we were doing reviews manually, now our tool handles some of these steps for us. It has allowed us to focus more on reviewing key items in our software.”

Developers can improve time, efficiency, and address issues earlier when conducting software code reviews. The result is a better, more productive product.

The NASA Stennis tool is part of the larger NASA Data Acquisition System created at the center to help monitor and collect propulsion test data. It is designed to work with National Instruments LabVIEW, which is widely used by systems engineers and scientists to design applications. LabVIEW is unique in using graphics (visible icon objects) instead of a text-based programming language to create applications. The graphical approach makes it more challenging to compare codes in a review process.

“You cannot compare your code in the same way you do with a text-based language,” Brandon Carver said. “Our tool offers a process that allows developers to review these LabVIEW-developed programs and to focus more time on reviewing actual code updates.”

LabVIEW features a comparison tool, but NASA Stennis engineers identified ways they could improve the process, including by automating certain steps. The NASA Stennis tool makes it easier to post comments, pictures, and other elements in an online peer review to make discussions more effective.  

The result is what NASA Stennis developers hope is a more streamlined, efficient process. “It really optimizes your time and provides everything you need to focus on right in front of you,” Brandon Carver said. “That’s why we wanted to open source this because when we were building the tool, we did not see anything like it, or we did not see anything that had features that we have.”

“By providing it to the open-source community, they can take our tool, find better ways of handling things, and refine it,” Brandon Carver said. “We want to allow those groups to modify it and become a community around the tool, so it is continuously improved. Ultimately, a peer review is to make stronger software or a stronger product and that is also true for this peer review tool.

“It is a good feeling to be part of the process and to see something created at the center now out in the larger world across the agency,” Brandon Carver said. “It is pretty exciting to be able to say that you can go get this software we have written and used,” he acknowledged. “NASA engineers have done this. I hope we continue to do it.”

Key Portion of NASA’s Roman Space Telescope Clears Thermal Vacuum Test

One half of NASA’s nearly complete Nancy Grace Roman Space Telescope just passed a lengthy test to ensure it will function properly in the space environment.

“This milestone tees us up to attach the flight solar array sun shield to the outer barrel assembly, and deployable aperture cover, which we’ll begin this month,” said Jack Marshall, who leads integration and testing for these elements at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “Then we’ll complete remaining environmental tests for the flight assembly before moving on to connect Roman’s two major assemblies and run the full observatory through testing, and then we’ll be ready to launch!”

Prior to this thermal testing, technicians integrated Roman’s deployable aperture cover, a visor-like sunshade, to the outer barrel assembly, which will house the telescope and instruments, in January, then added test solar panels in March. They moved this whole structure into the Space Environment Simulator test chamber at NASA Goddard in April.

There, it was subjected to the hot and cold temperatures it will experience in space. Next, technicians will join Roman’s flight solar panels to the outer barrel assembly and sunshade. Then the structure will undergo a suite of assessments, including a shake test to ensure it can withstand the vibrations experienced during launch.

Meanwhile, Roman’s other major portion — the spacecraft and integrated payload assembly, which consists of the telescope, instrument carrier, and two instruments — will undergo its own shake test, along with additional assessments. Technicians will install the lower instrument sun shade and put this half of the observatory through a thermal vacuum test in the Space Environment Simulator.

“The test verifies the instruments will remain at stable operating temperatures even while the Sun bakes one side of the observatory and the other is exposed to freezing conditions — all in a vacuum, where heat doesn’t flow as readily as it does through air,” said Jeremy Perkins, an astrophysicist serving as Roman’s observatory integration and test scientist at NASA Goddard. Keeping the instrument temperatures stable ensures their readings will be precise and reliable.

Technicians are on track to connect Roman’s two major parts in November, resulting in a complete observatory by the end of the year. Following final tests, Roman is expected to ship to the launch site at NASA’s Kennedy Space Center in Florida for launch preparations in summer 2026. Roman remains on schedule for launch by May 2027, with the team aiming for launch as early as fall 2026.

New Visualization From NASA’s Webb Telescope Explores Cosmic Cliffs

In July 2022, NASA’s James Webb Space Telescope made its public debut with a series of breathtaking images. Among them was an ethereal landscape nicknamed the Cosmic Cliffs. This glittering realm of star birth is the subject of a new 3D visualization derived from the Webb data. The visualization, created by NASA’s Universe of Learning and titled “Exploring the Cosmic Cliffs in 3D,” breathes new life into an iconic Webb image.

It is being presented today at a special event hosted by the International Planetarium Society to commemorate the 100^th anniversary of the first public planetarium in Munich, Germany.

The landscape of “mountains” and “valleys” known as the Cosmic Cliffs is actually a portion of the nebula Gum 31, which contains a young star cluster called NGC 3324. Both Gum 31 and NGC 3324 are part of a vast star-forming region known as the Carina Nebula Complex.

Ultraviolet light and stellar winds from the stars of NGC 3324 have carved a cavernous area within Gum 31. A portion of this giant bubble is seen above the Cosmic Cliffs. (The star cluster itself is outside this field of view.)

The Cliffs display a misty appearance, with “steam” that seems to rise from the celestial mountains. In actuality, the wisps are hot, ionized gas and dust streaming away from the nebula under an onslaught of relentless ultraviolet radiation.

Eagle-eyed viewers may also spot particularly bright, yellow streaks and arcs that represent outflows from young, still-forming stars embedded within the Cosmic Cliffs. The latter part of the visualization sequence swoops past a prominent protostellar jet in the upper right of the image.

Video: Exploring the Cosmic Cliffs in 3D

Produced for NASA by the Space Telescope Science Institute (STScI) with partners at Caltech/IPAC, and developed by the AstroViz Project of NASA’s Universe of Learning, this visualization is part of a longer, narrated video that provides broad audiences, including youth, families, and lifelong learners, with a direct connection to the science and scientists of NASA’s Astrophysics missions. That video enables viewers to explore fundamental questions in science, experience how science is done, and discover the universe for themselves.

“Bringing this amazing Webb image to life helps the public to comprehend the three-dimensional structure inherent in the 2D image, and to develop a better mental model of the universe,” said STScI’s Frank Summers, principal visualization scientist and leader of the AstroViz Project.

More visualizations and connections between the science of nebulas and learners can be explored through other products produced by NASA’s Universe of Learning including a Carina Nebula Complex resource page and ViewSpace, a video exhibit that is currently running at almost 200 museums and planetariums across the United States. Visitors can go beyond video to explore the images produced by space telescopes with interactive tools now available for museums and planetariums.

NASA’s Universe of Learning materials are based upon work supported by NASA under award number NNX16AC65A to the Space Telescope Science Institute, working in partnership with Caltech/IPAC, Center for Astrophysics | Harvard & Smithsonian, and NASA’s Jet Propulsion Laboratory.

The James Webb Space Telescope is the world’s premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and CSA (Canadian Space Agency).

NASA’s Universe of Learning is part of the NASA Science Activation program, from the Science Mission Directorate at NASA Headquarters. The Science Activation program connects NASA science experts, real content and experiences, and community leaders in a way that activates minds and promotes deeper understanding of our world and beyond. Using its direct connection to the science and the experts behind the science, NASA’s Universe of Learning provides resources and experiences that enable youth, families, and lifelong learners to explore fundamental questions in science, experience how science is done, and discover the universe for themselves.
