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 and a drive. Our primary…

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 occurred in Space Shuttle External…

Material Compatibility of Common Aerospace Metals in MMH/MON-3
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…

Considerations for Using Autonomous Flight Termination Software in 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. For uncrewed launch vehicles, FTS…

NASA Successfully Integrates Roman Mission’s Telescope, Instruments
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 preparation,” said Jody…

NASA’s Juno Mission Uncovers Heart of Jovian Moon’s Volcanic Rage
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 finding solves a 44-year-old mystery about the…

Sols 4389-4390: A Wealth of Ripples, Nodules and Veins
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, which focuses on the future drive path. Close to the rover,…
