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.  A flight test aboard a suborbital rocket system that will simulate lunar gravity is…

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…

The camera is facing west from a location nicknamed “Lookout Hill.”NASA/JPL-Caltech NASA’s Perseverance Mars rover captured this scene showing the slippery terrain that’s made its climb up to the rim of Jezero Crater challenging. Rover tracks can be seen trailing off into the distance, back toward the crater’s floor.NASA/JPL-Caltech The road ahead will be even more scientifically…

The telescope and instruments for NASA’s Nancy Grace Roman Space Telescope were recently integrated together on the observatory’s instrument carrier at the agency’s Goddard Space Flight Center in Greenbelt, Md. Next, the entire system will be joined to the Roman spacecraft. NASA/Chris Gunn NASA’s Nancy Grace Roman Space Telescope team has successfully integrated the mission’s telescope and two instruments onto the instrument carrier, marking the completion of the Roman payload. Now the team at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, will begin joining the payload to the spacecraft. “We’re in the middle of an exciting stage of mission…

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. BackgroundIn 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…

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 adding unique…

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 for all tested product forms, fluids, and durations…

Data from recent flybys is helping scientists understand Io’s interior. Image data: NASA/JPL-Caltech/SwRI/MSSSImage 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…
