When you think of NASA, disasters such as hurricanes may not be the first thing to come to mind, but several NASA programs are building tools and advancing science to help communities make more informed decisions for disaster planning.
Empowered by NASA’s commitment to open science, the NASA Disasters Program supports disaster risk reduction, response, and recovery. A core element of the Disasters Program is providing trusted, timely, and actionable data to aid organizations actively responding to disasters.
Hurricane Ida made landfall in Louisiana Aug. 21, 2021, as a category 4 hurricane, one of the deadliest and most destructive hurricanes in the continental United States on record. The effects of the storm were widespread, causing devastating damage and affecting the lives of millions of people.
During Hurricane Ida, while first responders and other organizations addressed the storm’s impacts from the ground, the NASA Disasters program was able to provide a multitude of remotely sensed products. Some of the products and models included information on changes in soil moisture, changes in vegetation, precipitation accumulations, flood detection, and nighttime lights to help identify areas of power outages.
Image Before/After The NASA team shared the data with its partners on the NASA Disasters Mapping Portal and began participating in cross-agency coordination calls to determine how to further aid response efforts. To further connect and collaborate using open science efforts, NASA Disasters overlaid publicly uploaded photos on their Damage Proxy Maps to provide situational awareness of on-the-ground conditions before, during, and after the storm.
Immediate post-storm response is critical to saving lives; just as making informed, long- term response decisions are critical to providing equitable recovery solutions for all. One example of how this data can be used is blue tarp detection in the aftermath of Hurricane Ida.
Using artificial intelligence (AI) with NASA satellite images, the Interagency Implementation and Advanced Concepts Team (IMPACT), based at NASA’s Marshall Space Flight Center in Huntsville, Alabama, conducted a study to detect the number of blue tarps on rooftops in the aftermath of hurricanes, such as Ida, as a way of characterizing the severity of damage in local communities.
An aerial photograph shows damaged roofs from Hurricane Maria in 2017 in Barrio Obrero, Puerto Rico. In the wake of the hurricane, the Federal Emergency Management Agency (FEMA) and United States Army Corps of Engineers distributed 126,000 blue tarps and nearly 60,000 temporary blue roofs to people awaiting repairs on damaged homes. NASA While disasters cannot be avoided altogether, timely and accessible information helps communities worldwide reduce risk, improve response, hasten recovery, and build disaster resilience.
Through an initiative led by NASA’s Office of the Chief Science Data Officer, NASA and IBM are developing five open-source artificial intelligence foundation models trained on NASA’s expansive satellite repositories. This effort will help make NASA’s vast, ever-growing amounts of data more accessible and usable. Leveraging NASA’s AI expertise allows users to make faster, more informed decisions. User applications of the Prithvi Earth Foundation Models could range from identifying flood risks and predicting crop yields to forecasting long range atmospheric weather patterns.
“NASA is dedicated to ensuring that our scientific data are accessible and beneficial to all. Our AI foundation models are scientifically validated and adaptable to new data, designed to maximize efficiency and lower technical barriers. This ensures that even in the face of challenging disasters, response teams can be swift and effective,” said Kevin Murphy, NASA’s chief science data officer. “Through these efforts, we’re not only advancing scientific frontiers, but also delivering tangible societal benefits, providing data that can safeguard lives and improve resilience against future threats.”

Outpost Technologies completed a high-altitude flight test of its Cargo Ferry, a reusable cargo transportation vehicle. The company dropped a full-scale prototype from 82,000 feet via weather balloon to test its recovery system and range capabilities. The key innovation is a robotic paraglider that guides the vehicle to a precise landing. The paraglider deployed at a record-setting altitude of 65,000 feet, marking the highest flight ever for such a system.
During the test, the vehicle autonomously flew 165 miles before it was safely recovered at the landing site, demonstrating the system’s reliability. The company’s low-mass re-entry system can protect payload mass and volume for future space cargo return missions and point-to-point delivery.

Internal defects are always formed in laser welding process due to the keyhole instability, molten pool collapse, and rapid solidification. The extreme lunar environment complicates the reliable implementation of welding, thereby enhancing the welding defects formation. The welding defects are critical material barriers preventing the metal components from Moon exploration. Professor Wei Li’s team will establish an integrated computational materials modelling framework to study the process-structure-property linkage of laser welding under the lunar conditions. The research is emphasized on modelling the internal defects (void, lack of fusion) formed in the lunar laser welding by fully considering the reduced gravity, large temperature change, and extreme vacuum on the Moon surface, and predicting the influence of internal defects on the material and mechanical properties of welding joint.

NASA NASA astronaut Alan Bean steps off the lunar module ladder in this photo from Nov. 19, 1969, joining astronaut Charles Conrad Jr. on the Moon in the area called the Ocean of Storms. The two would then complete two spacewalks on the lunar surface, deploying science instruments, collecting geology samples, and inspecting the Surveyor 3 spacecraft, which had landed in the same area. While Bean and Conrad worked on the Moon, astronaut Richard F. Gordon completed science from lunar orbit.
