official news from : https://bit.ly/2QkyIbY 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 itsContinue reading “NASA’s Perseverance Rover Reaches Top of Jezero Crater Rim”

official news from : https://bit.ly/2QkyIbY 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 ofContinue reading “2024 NESC Technical Update”

official news from : https://bit.ly/2QkyIbY 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 ifContinue reading “Considerations for Using Autonomous Flight Termination Softwarein Crewed Launch Vehicles”

official news from : https://bit.ly/2QkyIbY 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 aContinue reading “NASA Gives The World a Brake”

official news from : https://bit.ly/2QkyIbY 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 oceanContinue reading “NASA’s Juno Mission Uncovers Heart of Jovian Moon’s Volcanic Rage”

official news from : https://bit.ly/2QkyIbY 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 areContinue reading “Sols 4391-4392: Rounding the Bend”

official news from : https://bit.ly/2QkyIbY 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-3Continue reading “Material Compatibility of Common Aerospace Metals in MMH/MON-3”

official news from : https://bit.ly/2QkyIbY 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,Continue reading “Helium Conservation by Diffusion Limited Purging of Liquid Hydrogen Tanks”

official news from : https://bit.ly/2QkyIbY 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 theContinue reading “NASA Successfully Integrates Roman Mission’s Telescope, Instruments”

official news from : https://bit.ly/2QkyIbY Earth planning date: Monday, Dec. 9, 2024 We are continuing to edge our way around the large “Texoli” butte. Much of the bedrock we have been traversing recently looks pretty similar — paler-colored laminated bedrock — but today’s workspace had some interesting features, as did the “drive direction” image, whichContinue reading “Sols 4389-4390: A Wealth of Ripples, Nodules and Veins”
