Download PDF: Computational Modeling of Failure at the Fabric Weave Level in Reentry Parachute Energy Modulators Energy modulators (EM) are textile mechanical devices designed to dissipate snatch loads that occur when parachutes are deployed. Although critical for mitigating shock loads, recent flight testing has shown increasing variability in EM behavior, raising concerns about their performance predictability and […]

Ice to Fuel: NASA Tests Technology for Refueling Landers
The farther the destination, the more fuel a rocket needs. The more fuel the rocket carries, the heavier the spacecraft. The heavier the spacecraft, the more fuel it requires to launch. Experts at NASA’s Glenn Research Center in Cleveland are testing technology that could solve this problem. The CryoFILL (Cryogenic Fluid In-Situ Liquefaction for Landers) project could transform the way NASA fuels future space exploration missions, reducing costs and extending the duration of planetary surface operations. “If […]
Expanding the Human Factors Toolbox: An Approach to Balancing Crew and Mission Design Parameters
This article is from the 2025 Technical Update. The human factors TDT looks for and creates opportunities to influence design to leverage human strengths and to protect people and missions. The human factors team has experts with knowledge of human performance in all aspects of NASA missions as well as from other safety-critical industries. The […]
COPV Damage Tolerance Life Demonstration Guidelines
This article is from the 2025 Technical Update. The NESC has invested significant time and resources to better understand composite overwrapped pressure vessels (COPV) performance and more importantly, how these complex, high-pressure storage systems can fail. These vessels, which store high pressure propulsion and life-support system fluids on launch vehicles and spacecraft, are ubiquitous at NASA, and failures have […]
A Technical Resource for the Agency
This article is from the 2025 Technical Update. The NESC’s Thermal Control & Protection Technical Discipline Team (TDT) is a resource providing subject matter expertise in active and passive thermal control as well as ascent and entry thermal protection across the spectrum of agency needs. TDT members led or supported a variety of key activities […]
Celebrating NASA’s Mars Reconnaissance Orbiter’s 20th Anniversary: Crater Near Sirenum Fossae
NASA’s Mars Reconnaissance Orbiter (MRO) captures a detailed view of a relatively fresh crater in this image released on June 3, 2015. The crater has a sharp rim and well-preserved ejecta. The steep inner slopes are carved by gullies and include possible recurring slope lineae on the equator-facing slopes. This crater is monitored for changes […]
NASA Discovers Crash of Extreme Stars in Unexpected Site
A fleet of NASA missions has likely uncovered a collision between two ultradense stars in a tiny galaxy buried in a huge stream of gas. Astronomers have never seen this type of explosive event in an environment like this before — and it may help solve two outstanding cosmic mysteries. A paper describing these results […]
