Credit: NASA NASA, on behalf of the National Oceanic and Atmospheric Administration (NOAA), has awarded a delivery order to BAE Systems Space & Mission Systems Inc. of Boulder, Colorado, to build spacecraft for the Lagrange 1 Series project as a part of NOAA’s Space Weather Next program.
The award made under the Rapid Spacecraft Acquisition IV contract, has a total value of approximately $230.6 million with the period of performance running from February 2025 to February 2035. The work will take place at the awardee’s facility in Boulder.
The firm-fixed-price delivery order covers all phases of the Lagrange 1 Series project operations including developing up to two spacecraft, instrument integration, satellite-level testing, training and support for the spacecraft flight operations team, and mission operations support. Rapid IV contracts serve as a fast and flexible means for the government to acquire spacecraft and related components, equipment, and services in support of NASA missions and other federal government agencies.
The Space Weather Next program will maintain and extend space weather observations from various orbitally stable points such as Lagrange 1, which is about a million miles from Earth. The first Space Weather Next Lagrange 1 Series launch, planned in 2029, will be the first observatory under the program and will provide continuity of real-time coronal imagery and upstream solar wind measurements. Space Weather Next will provide uninterrupted data continuity when NOAA’s Space Weather Follow On Lagrange 1 mission comes to its end of operations.
Observations of the Sun and the near-Earth space environment are important to protecting our technological infrastructure both on the ground and in space. The spacecraft will provide critical data to NOAA’s Space Weather Prediction Center which issues forecasts, warnings and alerts that help mitigate space weather impacts, including electric power outages and interruption to communications and navigation systems.
NASA and NOAA oversee the development, launch, testing, and operation of all the satellites in the Lagrange 1 Series project. NOAA is the program owner providing the requirements and funding along with managing the program, operations, data products, and dissemination to users. NASA and its commercial partners develop and build the instruments, spacecraft, and provide launch services on behalf of NOAA.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA’s Sustainable Flight Demonstrator project concluded wind tunnel testing in the fall of 2024. Tests on a Boeing-built X-66 model were completed at NASA’s Ames Research Center in California’s Silicon Valley in its 11-Foot Transonic Unitary Plan Facility. The model underwent tests representing expected flight conditions to obtain engineering information to influence design of the wing and provide data for flight simulators.NASA/Brandon Torres Navarrete NASA’s Sustainable Flight Demonstrator (SFD) project recently concluded wind tunnel tests of its X-66 semi-span model in partnership with Boeing. The model, designed to represent half the aircraft, allows the research team to generate high-quality data about the aerodynamic forces that would affect the actual X-66.
Test results will help researchers identify areas where they can refine the X-66 design – potentially reducing drag, enhancing fuel efficiency, or adjusting the vehicle shape for better flying qualities.

Tests on a Boeing-built X-66 model were completed at NASA’s Ames Research Center in California’s Silicon Valley in its 11-Foot Transonic Unitary Plan Facility. Pressure points, which are drilled holes with data sensors attached, are installed along the edge of the wing and allow engineers to understand the characteristics of airflow and will influence the final design of the wing.NASA/Brandon Torres Navarrete Semi-span tests take advantage of symmetry. The forces and behaviors on a model of half an aircraft mirror those on the other half. By using a larger half of the model, engineers increase the number of surface pressure measurements. Various sensors were placed on the wing to measure forces and movements to calculate lift, drag, stability, and other important characteristics.
The semi-span tests follow earlier wind tunnel work at NASA’s Langley Research Center in Hampton, Virginia, using a smaller model of the entire aircraft. Engineers will study the data from all of the X-66 wind tunnel tests to determine any design changes that should be made before fabrication begins on the wing that will be used on the X-66 itself.
The SFD project is NASA’s effort to develop more efficient aircraft configurations as the nation moves toward aviation that’s more economically, societally, and environmentally sustainable. The project seeks to provide information to inform the next generation of single-aisle airliners, the most common aircraft in commercial aviation fleets around the world. Boeing and NASA are partnering to develop the X-66 experimental demonstrator aircraft.

Climate change presents one of the most urgent crises of our time, with increasing threats to life, infrastructure, economies, and ecosystems worldwide. Climate change is no longer a distant concern; its effects are being felt now and are projected to intensify if emissions continue unabated. The consequences are severe and irreversible for people today, with rapidly shrinking glaciers and ice sheets, rising sea levels, and more intense heat waves already occurring. Scientists predict even more profound impacts, such as an increase in the frequency and intensity of wildfires, extended drought periods, and stronger tropical cyclones. By 2100, sea levels could rise by up to 6.5 feet1, displacing coastal communities and disrupting ecosystems. In the U.S., the effects vary by region—wildfires in the West have doubled in area burned, and rising sea levels threaten infrastructure in the Southeast. Innovative, data-driven solutions are essential to mitigate these growing risks. From the unique vantage point in space, NASA collects critical long-term observations of our changing planet. NASA produces vast amounts of Earth system science data from satellites, radars, and ships, as well as model outputs, offering a wealth of opportunities for innovative thinkers to leverage these sources. The Sustainable Business Model Challenge is designed to identify and foster sustainable business models built around NASA’s Earth system science data. This challenge invites entrepreneurs, researchers, startups, and innovators to use NASA’s publicly available climate and Earth system data sources to create sustainable business models to address climate challenges.

This artist’s illustration represents the results from a new study that examines the effects of X-ray and other high-energy radiation unleashed on potential exoplanets from Wolf 359, a nearby red dwarf star. Researchers used Chandra and XMM-Newton to study the impact of steady X-ray and energetic ultraviolet radiation from Wolf 359 on the atmospheres of planets that might be orbiting the star. They found that only a planet with greenhouse gases like carbon dioxide in its atmosphere and at a relatively large distance away from Wolf 359 would have a chance to support life as we know it.X-ray: NASA/CXC/SAO/S.Wolk, et al.; Illustration: NASA/CXC/SAO/M.Weiss; Image processing: NASA/CXC/SAO/N. Wolk Planets around other stars need to be prepared for extreme weather conditions, according to a new study from NASA’s Chandra X-ray Observatory and ESA’s (European Space Agency’s) XMM-Newton that examined the effects of X-rays on potential planets around the most common type of stars.
Astronomers found that only a planet with greenhouse gases in its atmosphere like Earth and at a relatively large distance away from the star they studied would have a chance to support life as we know it around a nearby star.
Wolf 359 is a red dwarf with a mass about a tenth that of the Sun. Red dwarf stars are the most common stars in the universe and live for billions of years, providing ample time for life to develop. At a distance of only 7.8 light-years away, Wolf 359 is also one of the closest stars to the solar system.
“Wolf 359 can help us unlock the secrets around stars and habitability,” said Scott Wolk of the Center for Astrophysics | Harvard & Smithsonian (CfA), who led the study. “It’s so close and it belongs to such an important class of stars – it’s a great combination.”
Because red dwarfs are the most prevalent types of stars, astronomers have looked hard to find exoplanets around them. Astronomers have found some evidence for two planets in orbit around Wolf 359 using optical telescopes, but those conclusions have been challenged by other scientists.
“While we don’t have proof of planets around Wolf 359 yet, it seems very possible that it hosts multiple planets,” Wolk added. “This makes it an excellent test bed to look at what planets would experience around this kind of star.”
Wolk and his colleagues used Chandra and XMM to study the amounts of steady X-rays and extreme ultraviolet (UV) radiation – the most energetic type of UV radiation – that Wolf 359 would unleash on the possible planets around it.
They found that Wolf 359 is producing enough damaging radiation that only a planet with greenhouse gases like carbon dioxide in its atmosphere – and located at a relatively large distance from the star – would likely be able to sustain life.
“Just being far enough away from the star’s harmful radiation wouldn’t be enough to make it habitable,” said co-author Vinay Kashyap, also of CfA. “A planet around Wolf 359 would also need to be blanketed in greenhouse gases like Earth is.”
To study the effects of energetic radiation on the habitability of the planet candidates, the team considered the star’s habitable zone – the region around a star where liquid water could exist on a planet’s surface.
The outer limit of the habitable zone for Wolf 359 is about 15% of the distance between Earth and the Sun, because the red dwarf is much less bright than the Sun. Neither of the planet candidates for this system is located in Wolf 359’s habitable zone, with one too close to the star and the other too far out.
“If the inner planet is there, the X-ray and extreme UV radiation it is subjected to would destroy the atmosphere of this planet in only about a million years,” said co-author Ignazio Pillitteri of CfA and the National Institute for Astrophysics in Palermo, Italy.
The team also considered the effects of radiation on as-yet undetected planets within the habitable zone. They concluded that a planet like the Earth in the middle of the habitable zone should be able to sustain an atmosphere for almost two billion years, while one near the outer edge could last indefinitely, helped by the warming effects of greenhouse gases.
Another big danger for planets orbiting stars like Wolf 359 is from X-ray flares, or occasional bright bursts of X-rays, on top of the steady, everyday output from the star. Combining observations made with Chandra and XMM-Newton resulted in the discovery of 18 X-ray flares from Wolf 359 over 3.5 days.
Extrapolating from these observed flares, the team expects that much more powerful and damaging flares would occur over longer periods of time. The combined effects of the steady X-ray and UV radiation and the flares mean that any planet located in the habitable zone is unlikely to have a significant atmosphere long enough for multicellular life, as we know it on Earth, to form and survive. The exception is the habitable zone’s outer edge if the planet has a significant greenhouse effect.
These results were presented at the 245th meeting of the American Astronomical Society in National Harbor, Maryland, and are being prepared for publication in a journal. NASA’s Marshall Space Flight Center in Huntsville, Alabama, manages the Chandra program. The Smithsonian Astrophysical Observatory’s Chandra X-ray Center controls science operations from Cambridge, Massachusetts, and flight operations from Burlington, Massachusetts.
