      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      2024 intro: As NASA’s Ames Research Center in California’s Silicon Valley enters its 85th year since its founding, join us as we take a look back at some of our highlights of science, engineering, research, and innovation from 2024.
      Ames Arc Jets Play Key Role in Artemis I Orion Spacecraft Heat Shield Findings 
      A block of Avcoat undergoes testing inside an arc jet test chamber at NASA Ames. The test article, configured with both permeable (upper) and non-permeable (lower) Avcoat sections for comparison, helped to confirm understanding of the root cause of the loss of charred Avcoat material that engineers saw on the Orion spacecraft after the Artemis I test flight beyond the Moon. NASA Researchers at Ames were part of the team tasked to better understand and identify the root cause of the unexpected char loss across the Artemis I Orion spacecraft’s heat shield. Using Avcoat material response data from Artemis I, the investigation team was able to replicate the Artemis I entry trajectory environment — a key part of understanding the cause of the issue — inside the arc jet facilities at NASA Ames.

      Video: 00:11:10 In 2024, ESA continued to drive Europe’s innovation and excellence in space, equipping the continent with advanced tools and knowledge to address global and local challenges. The year saw pioneering missions, cutting-edge satellites and the pivotal restoration of Europe’s independent access to space. 
      The first Ariane 6 launch was perhaps ‘the’ highlight of the year but it was only one of many achievements. We saw the last Vega launch and then the return to flight of Vega-C, the more powerful, upgraded version carrying Sentinel-1C.
      Far away in our Solar System, the ESA/JAXA BepiColombo spacecraft performed twoMercury flybys in 2024, needed so that it can enter orbit around Mercury in 2026. Juice also performed a crucial gravity assist, this time becoming the first spacecraft to conduct a Moon-Earth double flyby on its way to Jupiter. 
      Twenty years after ESA’s Rosetta was launched and 10 years since its historic arrival at the comet 67P/Churyumov-Gerasimenko, we launched another spacecraft to a small body, the Hera planetary defence mission to investigate asteroid Dimorphos.
      2024 was an important year for Europe’s Galileo constellation which continued to expand with the launch of four new satellites and an updated Galileo ground system. The year also saw the launch of ESA’s Proba-3 mission: two precision formation-flying satellites forming a solar coronagraph to study the Sun’s faint corona. 
      In human spaceflight, Europe continues to contribute to science from the ISS as Andreas Mogensen’s Huginn mission continued into 2024. Andreas even met up in space with ESA project astronaut Marcus Wandt who was launched on his Muninn mission, making it the first time two Scandinavians were in space together. 
      Meanwhile the latest class of ESA astronauts completed basic training and graduated in April. Two of them, Sophie and Raphaël, were then assigned to long-duration missions to the ISS in 2026.
      We made crucial steps for Europe in gaining access to the Moon: the inauguration of our LUNA facility with DLR, and the delivery of a third European Service Module for NASA’s Orion spacecraft as part of the Artemis programme.
      Europe is also contributing to the international Lunar Gateway and developing and ESA lunar lander called Argonaut. These landers will rely on ESA Moonlight, the programme to establish Europe’s first dedicated satellite constellation for lunar communication and navigation.
      As 2024 draws to a close, ESA’s achievements this year have reinforced Europe’s role in space. ESA’s journey continues to explore new frontiers, shaping the space landscape for generations to come.

      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 requirements for reuse of software originally intended for uncrewed missions. This bulletin summarizes new information relating to AFTS to raise awareness of key distinctions, summarize considerations and outline best practices for incorporating AFTS into human-rated systems.
      Key Distinctions – Crewed v. Uncrewed
      There are inherent behavioral differences between uncrewed and crewed AFTS related to design philosophy and fault tolerance. Uncrewed AFTS generally favor fault tolerance against failure-to-destruct over failing silent
      in the presence of faults. This tenet permeates the design, even downto the software unit level. Uncrewed AFTS become zero-fault-to-destruct tolerant to many unrecoverable AFTS errors, whereas general single fault
      tolerance against vehicle destruct is required for crewed missions. Additionally, unique needs to delay destruction for crew escape, provide abort options and special rules, and assess human-in-the-loop insight, command, and/or override throughout a launch sequence must be considered and introduces additional requirements and integration complexities.

      AFTS Software Architecture Components and Best-Practice Use Guidelines
      A detailed study of the sole AFTS currently approved by USSF and utilized/planned for several launch vehicles was conducted to understand its characteristics, and any unique risk and mitigation techniques for effective human-rating reuse. While alternate software systems may be designed in the future, this summary focuses on an architecture employing the Core Autonomous Safety Software (CASS). Considerations herein are intended for extrapolation to future systems. Components of the AFTS software architecture are shown, consisting of the CASS, “Wrapper”, and Mission Data Load (MDL) along with key characteristics and use guidelines. A more comprehensive description of each and recommendations for developmental use is found in Ref. 1.
      Best Practices Certifying AFTS Software
      Below are non-exhaustive guidelines to help achieve a human-rating
      certification for an AFTS.
