NASA/Steve Freeman On Oct. 22, 2024, the latest iteration of an atmospheric probe developed by researchers at NASA’s Armstrong Flight Research Center in Edwards, California, successfully completed a test flight. Building on NASA 1960s research on lifting body aircraft, which use the aircraft’s shape for lift instead of wings, the concept could offer future scientists a potentially better and more economical way to collect data on other planets. Testing demonstrated the shape of the probe works. The atmospheric probe flew after release from a quad-rotor remotely piloted aircraft above Rogers Dry Lake, a flight area adjacent to NASA Armstrong. “I’m ecstatic,” said Joh…

5 Min Read NASA Technologies Aim to Solve Housekeeping’s Biggest Issue – Dust This artist rendering of Electrostatic Dust Lofting (EDL) examines the lofting of lunar dust when electrostatic charging occurs after exposure to ultraviolet light. If you thought the dust bunnies under your sofa were an issue, imagine trying to combat dust on the Moon. Dust is a significant challenge for astronauts living and working on the lunar surface. So, NASA is developing technologies that mitigate dust buildup enabling a safer, sustainable presence on the Moon. …

An artist’s concept of the Earth, Moon, and Mars.Credit: NASA As NASA develops a blueprint for space exploration throughout the solar system for the benefit of humanity, the agency released several new documents Friday updating its Moon to Mars architecture. The roadmap sets NASA on course for long-term lunar exploration under the Artemis campaign in preparation for future crewed missions to Mars. Following an Architecture Concept Review, the 2024 updates include a revision of NASA’s Architecture Definition Document which details technical approaches and processes of the agency’s exploration plans, an executive overview, and 12 new white papers on key Moon to Mars…

ESA/Hubble & NASA, R. Windhorst, W. Keel This NASA/ESA Hubble Space Telescope image features a spiral galaxy, named UGC 10043. We don’t see the galaxy’s spiral arms because we are seeing it from the side. Located roughly 150 million light-years from Earth in the constellation Serpens, UGC 10043 is one of the somewhat rare spiral galaxies that we see edge-on. This edge-on viewpoint makes the galaxy’s disk appear as a sharp line through space, with its prominent dust lanes forming thick bands of clouds that obscure our view of the galaxy’s glow. If we could fly above the galaxy, viewing it from the top down, we would see this dust scattered across UGC 10043, possi…

This article is from the 2024 Technical Update. Multiple human spaceflight programs are underway at NASA including Orion, Space Launch System, Gateway, Human Landing System, and EVA and Lunar Surface Mobility programs. Achieving success in these programs requires NASA to collaborate with a variety of commercial partners, including both new spaceflight companies and robotic spaceflight companies pursuing crewed spaceflight for the first time. It is not always clear to these organizations how to show their systems are safe for human spaceflight. This is particularly true for avionics systems, which are responsible for performing some of a crewed spacecraft’s most c…

This article is from the 2024 Technical Update. In 2015, the NESC released benchmark Earth-based check-cases for well specified, rigid-body, six-degree-of-freedom (6DOF) aero/spacecraft models to promote consistent and accurate flight simulations across multiple Agency tools and facilities. Recently, the NESC expanded upon that effort to add Lunar-based check-cases to support new lunar exploration initiatives. This study produced a smaller, focused set of cases that exercise new and unique features of missions in the lunar environment in comparison with 8 high-fidelity NASA simulation tools and provides a measure of validation for simulations supporting Human Lan…

This article is from the 2024 Technical Update. The NASA Engineering and Safety Center (NESC) has developed an analytical model that predicts diffusion between two gases during piston purging of liquid hydrogen (LH2) tanks. This model helps explain dramatic helium savings seen in a recent Kennedy Space Center (KSC) purge, shows that undesired turbulent mixing occurred in Space Shuttle External Tank purges, and is applicable to future helium purges of the Space Launch System Core Stage LH2 tanks. Background In 2023, work was completed on a new 1.3-million-gallon (174,000 standard cubic feet (scf)) liquid hydrogen tank at KSC in support of the Space Launch Sys…

This article is from the 2024 Technical Update Autonomous flight termination systems (AFTS) are being progressively employed onboard launch vehicles to replace ground personnel and infrastructure needed to terminate flight or destruct the vehicle should an anomaly occur. This automation uses on-board real-time data and encoded logic to determine if the flight should be self-terminated. For uncrewed launch vehicles, FTS systems are required to protect the public and governed by the United States Space Force (USSF). For crewed missions, NASA must augment range AFTS requirements for crew safety and certify each flight according to human rating standards, thus addin…

This article is from the 2024 Technical Update. The NESC evaluated material compatibility of some common aerospace metals in monomethylhydrazine (MMH) and nitrogen tetroxide (MON-3). Previous work had identified a lack of quantitative compatibility data for nickel alloy 718, 300 series stainless steel, and titanium Ti-6Al-4V in MMH and MON-3 to support the use of zero-failure-tolerant, thin-walled pressure barriers in these propellants. Static (i.e., not flowing) general corrosion and electrochemistry testing was conducted, evaluating varied processing forms and heat treatment of the metals, water content of propellant, and exposure duration. Corrosion-rate data …

5 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) The north polar region of Jupiter’s volcanic moon Io was captured by NASA’s Juno during spacecraft’s 57th close pass of the gas giant on Dec. 30, 2023. Data from recent flybys is helping scientists understand Io’s interior. Image data: NASA/JPL-Caltech/SwRI/MSSS Image processing by Gerald Eichstädt A new study points to why, and how, Io became the most volcanic body in the solar system. Scientists with NASA’s Juno mission to Jupiter have discovered that the volcanoes on Jupiter’s moon Io are each likely powered by their own chamber of roiling hot magma rather than an ocean of magma. The…
