Hubble Captures an Edge-On Spiral with Curve Appeal
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 […]

NASA Kennedy Top 24 Stories of 2024
From sending crew members to the International Space Station to launching a spacecraft to Jupiter?s icy moon Europa to determine if it could support life, 2024 was a busy record setting year for NASA and its partners at Kennedy Space Center in Florida. JANUARYFirst Lunar Lander Takes Flight The first flight of NASA?s CLPS (Commercial […]

NASA?s Perseverance Rover Reaches Top of Jezero Crater Rim
The road ahead will be even more scientifically intriguing, and probably somewhat easier-going, now that the six-wheeler has completed its long climb to the top. NASA?s Perseverance Mars rover has crested the top of Jezero Crater?s rim at a location the science team calls ?Lookout Hill? and rolling toward its first science stop after the […]

2024 NESC Technical Update
Annual Report of NESC Technical Activities On behalf of the NASA Engineering and Safety Center (NESC), I am pleased to provide you with the 2024 NESC Technical Update. This annual report summarizes the technical work, engineering advancements, and knowledge capture efforts we made in FY24. With support provided by members of our NASA community from across […]

NASA Gives The World a Brake
Just as NASA needs to reduce mass on a spacecraft so it can escape Earth?s gravity, automotive manufacturers work to reduce weight to improve vehicle performance. In the case of brake rotors, lighter is better for a vehicle?s acceleration, reliable stopping, and even gas mileage. Orbis Brakes Inc. licensed a NASA-patented technology to accomplish that […]

Key Considerations When Developing Avionics for Safety-Critical Systems
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 […]

6DOF Check Cases
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 […]

Sols 4391-4392: Rounding the Bend
Earth planning date: Wednesday, Dec. 11, 2024 For planning today, we have a beautiful view of the northern tip of Texoli, as seen in the image foreground. Unfortunately, the rocks that make the view so pretty also made it unsafe to unstow the arm for contact science. Instead we are doing a lot of imaging [?]

Helium Conservation by Diffusion Limited Purging of Liquid Hydrogen Tanks
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 […]

Considerations for Using Autonomous Flight Termination Softwarein Crewed Launch Vehicles
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. […]
