NASA Awards Advance 3D Printing, Quantum Tech for Climate Research
New technology is a key to helping NASA advance its long-term exploration goals for the benefit of all. To support its effort, the agency announced Thursday it will create two new institutes to develop technology in critical areas for engineering and climate research.
Two new Space Technology Research Institutes (STRIs) will leverage teams led by U.S. universities to create multidisciplinary research and technology development programs critical to NASA’s future. By bringing together science, engineering, and other disciplines from universities, industry, and non-profits, the institutes aim to impact future aerospace capabilities through investments in early-stage technology.
One of the research institutes will focus on quantum sensing technology in support of climate research. The other will work to improve understanding and help enable rapid certification of metal parts created using advanced manufacturing techniques.
“We’re thrilled to draw on the expertise of these multi-university teams to create technology for some of our most pressing needs,” said Jim Reuter, associate administrator for the agency’s Space Technology Mission Directorate at NASA Headquarters in Washington. “Their work will enable next-generation science for studying our home planet and broaden the use of 3D-printed metal parts for spaceflight with state-of-the-art modeling.”
Each institute will receive up to $15 million over five years.
Quantum Pathways Institute
The University of Texas at Austin will lead the Quantum Pathways Institute, focused on advancing quantum sensing technology for next-generation Earth science applications. Such technology would enable new understanding of our planet and the effects of climate change.
Quantum sensors use quantum physics principles to potentially collect more precise data and enable unprecedented science measurements. These sensors could be particularly useful for satellites in orbit around Earth to collect mass change data – a type of measurement that can tell scientists about how ice, oceans, and land water are moving and changing. Though the basic physics and technology for quantum sensors have been proven in concept, work is required to develop quantum sensors at the precisions necessary for next-generation science needs during spaceflight missions.
“Quantum sensing methods have shown a great deal of promise in computing, communications, and now for Earth science remote sensing applications,” said Dr. Srinivas Bettadpur, principal investigator for the institute and professor of aerospace engineering and engineering mechanics at the University of Texas at Austin. “Our intent is to advance this technology and get it ready for space as soon as we can.”
The institute will work to further advance the physics underlying quantum sensors, design how these sensors could be built for space missions and understand how mission design and systems engineering would need to adapt to accommodate this new technology.
Partners on the institute include University of Colorado Boulder; University of California, Santa Barbara; California Institute of Technology; and the National Institute of Standards and Technology.
Institute for Model-Based Qualification & Certification of Additive Manufacturing (IMQCAM)
Carnegie Mellon University in Pittsburgh will lead Institute for Model-based Qualification & Certification of Additive Manufacturing (IMQCAM) aiming to improve computer models of 3D-printed – also called additively manufactured – metal parts and expand their utility in spaceflight applications. The institute will be co-led by Johns Hopkins University in Baltimore.
Metal parts 3D-printed are made from powdered metals, which are melted in specific ways and shaped into useful parts. Such parts could be useful for things like rocket engines – giving more flexibility to create new parts when designs change – or as part of a human outpost on the Moon, where bringing pre-fabricated parts would be expensive and limiting. However, efficient certification and use of such parts requires high-accuracy predictions of their characteristics.
“The internal structure of this type of part is much different than what’s produced by any other method,” said Tony Rollett, principal investigator for the institute and US Steel professor of metallurgical engineering and materials science at Carnegie Mellon University. “The institute will focus on creating the models NASA and others in industry would need to use these parts on a daily basis.”
Detailed computer models, known as digital twins, will allow engineers to understand the parts’ capabilities and limitations – such as how much stress the parts can take before breaking. Such models will provide the predictability of part properties based on their processing that is key for certifying the parts for use. The institute will develop digital twins for 3D-printed parts made from spaceflight materials that are commonly used for 3D printing, as well as evaluating and modeling new materials.
Somnath Ghosh, the Michael G. Callas professor in civil and systems engineering at Johns Hopkins University’s Whiting School of Engineering, will serve as the co-principal investigator and will co-direct the institute, along with Rollett. Additional partners on the institute include Vanderbilt University, University of Texas at San Antonio, University of Virginia, Case Western Reserve University, Johns Hopkins University Applied Physics Laboratory, Southwest Research Institute, and Pratt & Whitney.

Mysterious Lights Over Oregon: Pilots Report Unusual Aerial Phenomena
This past weekend, the skies of Oregon became the backdrop for an extraordinary event that has both puzzled and dazzled observers. At least four commercial pilots reported encountering unexplained bright lights displaying incredible speeds and erratic movements, renewing interest and debate about aerial phenomena.
The Encounter Details
The first report came from a pilot operating an air ambulance who described a startling experience. A bright, red light zoomed towards his Life Flight plane, only to reverse direction and head back towards the Pacific Ocean at bewildering speeds. The event left the pilot and his crew astounded by the light’s velocity and abrupt maneuvers.
Meanwhile, the pilot of a United Airlines flight over Eugene also reported seeing multiple mysterious objects. These unidentified lights moved vertically and horizontally in patterns that defied easy explanation, with no evidence of military activity in the area at the time.
Adding to the intrigue, the Life Flight pilot noted that one of the lights engaged in a corkscrew pattern, an observation that was corroborated by the aircraft’s collision avoidance system. Air traffic control, maintaining a cautious approach, authorized the pilot to maneuver as necessary to maintain safety.

Visual Evidence and Continued Sightings
Throughout these encounters, several pilots managed to capture brief video clips. These clips, although hard to discern due to the dark conditions, show glimpses of the unusual red, circular lights. Another report from two Horizon Airlines pilots further confirmed that whatever was out there wasn’t isolated to a single incident or observer.
Experts Weigh In: Possible Explanations
In the wake of these mystifying sightings, experts have been quick to offer explanations. Douglas Buettner, a scientist who has researched similar incidents, suggests that these lights could likely be flares from Starlink satellites. Starlink, a constellation designed by SpaceX to provide global broadband coverage, has been known to produce vivid optical flares when its panels reflect sunlight.
Buettner’s research, which includes previous pilot reports and observations, supports the idea that this natural reflection of sunlight could explain the phenomena observed. However, he also admits the current data is insufficient to conclusively rule out other possibilities.
Government and Public Response
Following these reports, the Federal Aviation Administration (FAA) confirmed the sighting of unidentified lights by a pilot, although they have not commented further. In a recent Senate hearing, the Pentagon’s director overseeing unidentified anomalous phenomena indicated a spike in such reports since the launch of satellite constellations like Starlink, underscoring the growing interest and concern regarding these observations.
The Broader Implications
While the most likely explanation for these mysterious lights points to satellite flares, the repeated occurrences of such phenomena continue to stir the public’s imagination and scientific curiosity. As we advance in our technological capabilities, the skies above us grow increasingly populated with human-made objects that can sometimes return to us as bewildering spectacles.
In either case, these events serve as a reminder of the vast and unexplored frontiers above us and the ever-present human quest for understanding the mysteries of our universe. Whether they turn out to be mundane or truly otherworldly, the skies over Oregon this weekend have given us all something to ponder and marvel at.

New Jersey Drone Sightings: Unraveling the Mystery
In recent weeks, New Jersey has increasingly found itself under the watchful eye of mysterious drones. These sightings have captivated residents and officials alike, leading to widespread speculation and calls for action. Below is a comprehensive update on the current situation regarding drone sightings in the Garden State, including insights from government officials and community reactions.
The Surge of Sightings
Reports of large drones—up to six feet in diameter—flying over various regions of New Jersey have surged since mid-November. Assemblywoman Dawn Fantasia highlighted the unusual characteristics of these drones, often flying with their lights off and evading detection by traditional methods. Though the origin and purpose of these drones remain unclear, many are convinced that they are not the product of hobbyists.
Notably, many sightings have been concentrated near sensitive locations such as the Picatinny Arsenal, a U.S. military research facility, and Trump National Golf Club in Bedminster. Concerns have only intensified since these drones seem to be operating outside the realm of normal commercial or recreational use.
Government Investigations and Assurances
Federal and state law enforcement agencies, including the FBI and the Department of Homeland Security (DHS), have become actively involved in investigating these sightings. Despite receiving over 5,000 tips, officials state that there is currently no evidence suggesting that these drones pose a threat to national security or public safety. Instead, authorities believe that many of the reported sightings can be attributed to legal drones and other aerial phenomena, including misidentified manned aircraft and even celestial bodies like stars.
Governor Phil Murphy has reinforced this perspective, emphasizing that while drone sightings have raised valid concerns, there’s no immediate threat to public safety. The governor has called for federal assistance in the investigation and urged Congress to empower states with more authority to manage drone activities.
Congressional Response and Public Sentiment
The situation has sparked a debate among lawmakers, with some calling for stricter regulations or even a temporary ban on drone flights in New Jersey. Notably, two congressional representatives have gone so far as to request that the military intervene, highlighting the urgency felt by some constituents. U.S. Rep. Jeff Van Drew even suggested that a foreign entity could be behind the sightings, a theory that has been categorically denied by federal officials.
Public sentiment varies significantly, with many residents expressing concerns about the unknown nature of these drones. James Edwards from Succasunna has pointed out the anxiety gripping the community, noting, “There’s so much that’s unknown,” and calling for a measured response to the sightings.
The View from Washington
At the national level, President Joe Biden has responded to the growing unease, asserting that there is nothing nefarious behind the drone sightings. He emphasized the lawful presence of over one million registered drones operating across the country and assured the public that the situation is being closely monitored.
John Kirby, the White House National Security Advisor, reiterated that the majority of drone sightings do not indicate a coordinated threat and stem from common commercial, hobbyist, or law enforcement operations.
What Lies Ahead?
As investigations continue, officials stress the importance of discerning legitimate threats from unwarranted fears. The situation remains fluid, with ongoing dialogues both in Trenton and Washington to address public concerns and craft appropriate regulatory responses.
While the mystery of the New Jersey drones deepens, it’s vital for residents to remain calm and informed. As the investigation unravels the truths behind these sightings, a collective effort from the community, lawmakers, and federal agencies can help ensure safety and transparency in the skies above New Jersey.
Stay tuned for updates as this story continues to evolve, and be sure to report any new sightings or information to the appropriate authorities. Together, we can navigate the complexities of drone activity in our airspace while embracing this new technological frontier.

Learning from Voices of War: Honoring the 80th anniversary of World War II’s final major battle
(Family Features) The Ardennes Offensive, commonly known as the “Battle of the Bulge,” stands as the single bloodiest battle fought by the United States during World War II. Waged in the bitter cold of mid-December 1944, it took the Allies a month to secure victory. The cost was staggering: nearly 20,000 Americans were killed in action, close to 50,000 wounded and another 20,000 captured.
In honor of the 80th anniversary of this pivotal battle, the Library of Congress Veterans History Project has launched an online exhibit to commemorate the milestone. While the battle itself is etched in the annals of history, the personal stories from those who endured it remain one of the most powerful testaments to its impact.
The online exhibit, “Serving Our Voices,” features accounts from 12 Battle of the Bulge survivors, part of the thousands of narratives preserved by the project. These stories ensure future generations can gain deeper understanding of veterans’ service and sacrifice.
One such story includes Eliot Annable, a 20-year-old radio operator serving with the Army’s 106th Infantry Division. Just days after arriving at the western front, Annable found himself under German artillery barrages on. Dec. 16, 1944. He recalled the assault in his oral history, describing the intensity as “almost enough to knock you on the floor.”
The following five days became the most harrowing days of Annable’s military service. While on a communications mission, he became stranded behind enemy lines and spent nearly a week evading the enemy in the Ardennes Forest without food, shelter or appropriate winter clothing. After traveling more than 30 miles, he eventually safely rejoined the remnants of his unit.
Back home, Annable’s parents were gripped by uncertainty. On Dec. 31, 1944, his father wrote a letter expressing the family’s anguish and love for their son, regardless of what happened. The moving letter, coupled with Annable’s oral history, provides an intimate view into one soldier’s Battle of the Bulge experience.
Another featured veteran in the exhibit, Guy Martin Stephens, also served with the 106th Infantry Division. Unlike Annable, Stephens was captured by the Germans during battle. In his oral history, he recounted the surreal feeling of combat, the relentless hunger he endured as a prisoner of war and the lingering effects of his time in captivity.
“It’s hard,” Stephens said. “It’s something you can’t ever … your mind is just like a video, or camcorder, I guess. You put it in there. You get busy and get married. You get home, and you get an education, and get a job, and raise your family and everything like that. You can kind of gloss it over or try to push it back, but it’s always there, you know?”
Veterans who served during the 20th or 21st centuries are invited to establish a collection, including interviews (video or audio), letters and original photographs, even if they did not see combat. Families can also submit collections posthumously to honor their loved ones. To explore more veterans’ stories and learn how you can contribute to the program, visit loc.gov/vets.
