In-space manufacturing and assembly are vital to NASA’s long-term exploration goals, especially for the Moon and Mars missions. Deploying welding technology in space enables the assembly and repair of structures, reducing logistical burdens and supply needs from Earth. The unique challenges and extreme conditions of space–high thermal variations, microgravity, and vacuum–require advanced welding techniques and computational tools to ensure reliability, repeatability, safety, and structural integrity in one-shot weld scenarios. For the first time, this project investigates these challenges by focusing on three key factors: (1) Very low temperatures in space degrade the weldability of high thermal conductivity materials, like aluminum alloys, making it harder to achieve strong, defect-free welds. (2) The extreme vacuum in space lowers the boiling points of alloying elements, altering the keyhole geometry during welding. This selective vaporization changes the weld’s final chemical composition, affecting its microstructure and properties. (3) Microgravity nearly eliminates buoyancy-driven flow of liquid metal inside the molten pool, preventing gas bubbles from escaping, which leads to porosity and defects in the welds. By examining these critical factors using multi-scale multi-physics models integrated with physics-informed machine learning, and forward/inverse uncertainty quantification techniques, this project provides the first-ever real-time digital twin platform to evaluate welding processes under extreme space/lunar conditions. The models are validated through Earth-based experiments, parabolic flight tests, and publicly available data from different databases and agencies worldwide. Moreover, the established models will facilitate extendibility to support in-situ resource utilization on the Moon, including construction and repair using locally sourced materials like regolith. The established fundamental scientific knowledge will minimize trial-and-error, enable high-quality one-shot welds in space, and reduce the need for reworks, significantly reducing the costs and time needed for space missions.

The Colares UFO incidents refer to a series of unusual sightings and encounters that took place in 1977 on the Brazilian island of Colares. During this period, numerous residents from the Amazon River community of Colares reported being attacked by UFOs.
These mysterious objects allegedly descended from the sky, and in some cases, emerged from the water, emitting intense beams of light. The beams caused physical harm, including burn marks, puncture wounds, fatigue, and memory loss, affecting as many as 2,000 people.
In response to the alarming situation, the Brazilian Air Force initiated a thorough investigation. Years later, their findings were made public, revealing details of this bizarre chapter in UFO history.
Weaponized hosts Jeremy and George speak with Thiago Ticchetti, Brazil's leading UFO investigator and author, to discuss the Colares case and the once-classified military files.
According to Thiago, the Brazilian military captured remarkably clear film footage and photographs of the UFOs. However, he claims that this evidence was sent to the U.S. and has never been released to the public.
In this episode, they also explores various conspiracy theories and recent debunking efforts surrounding the topic of unidentified aerial phenomena (UAP).
The discussion on the Colares UFO incidents begins at the 37-minute mark in the video.

NASA Summer Camp Inspires Future Climate Leaders
From July 15-19, 2024, the Coastal Equity and Resilience Hub at the Georgia Institute of Technology collaborated with the University of Georgia (UGA) Marine Extension and Georgia Sea Grant to host a week-long NASA Sea Level Changemakers Summer Camp. The camp introduced 14 rising 7th-8th graders to how coastal areas are changing due to sea level rise. Set at the UGA Marine Education Center and Aquarium on Skidaway Island, the camp offered students hands-on activities and outdoor educational experiences, where they analyzed real data collected by NASA scientists and learned about community adaptations to flooding. Students interacted with experts from NASA’s Jet Propulsion Laboratory, UGA, and Georgia Tech, gaining insights into satellite observations, green infrastructure, environmental sensors, and careers related to sea level rise. The camp also included a visit to the Pin Point Heritage Museum, where students engaged with leaders from the historic Gullah Geechee community of Pin Point. The camp concluded with a boat trip to Wassaw Island, where students observed the effects of sea level rise on an undeveloped barrier island and compared these observations with earlier findings from urban environments. Funding from the NASA’s Science Activation Program and its Sea Level Education, Awareness, and Literacy (SEAL) team ensured that the camp was accessible to all students, eliminating financial barriers for groups traditionally underrepresented in STEM education.
“This investment from NASA has provided an amazing opportunity for youth in coastal Georgia to utilize NASA data and resources on a critical issue affecting their communities,” said Jill Gambill, executive director of the Coastal Equity and Resilience (CEAR) Hub at Georgia Tech. “They have more confidence now in their knowledge of sea level rise and potential solutions.”
The Sea Level Education, Awareness, and Literacy (SEAL) team is supported by NASA under cooperative agreement award number NNH21ZDA001N-SCIACT and is part of NASA’s Science Activation Portfolio.

“Some people [may say], ‘You have too many cooks in the kitchen,’ but I think there’s a line. It’s good to have a lot of input because people bring many different perspectives that you would never even consider if you just pushed an idea forward with one person. This is especially true in the area we work in with digital [communications], which is changing so frequently; you constantly have to innovate, so including diverse voices and thoughts is important.
“I’m an older sister, and I don’t know if some of that [leadership style] comes from when we were kids, always making sure that I involved her and ensuring people could understand what she wanted or needed. And maybe that translated into who I am, making sure people have voices and are heard [at NASA]…I’ve achieved a lot that I didn’t even know I wanted to accomplish because I couldn’t have imagined this career progression for myself.
“But now that I’m here, I would like to achieve more in terms of what NASA looks like internally, especially after getting involved with the NASA Science IDEA working group and diversity efforts. I would love to one, help people outside of NASA realize that they could work here and two, push people internally to the forefront so that they can be considered for higher-level things and progress.”
