The NASA robotic in-space assembly teams at Langley and Ames have come together to sponsor the "Robotic Assembly and Outfitting for NASA Space Missions" challenge on GrabCAD! I want to get the word out so that anyone interested can share their ideas with us, help shape NASA's future in-space assembly work, and receive a cash prize for top tier ideas. Please take a look and share with your network! We're interested in anything concepts relating to building structures from modules or components in space or on the surface of the Moon and Mars. The sort of structures we'd like to build and outfit on the Lunar surface would focus on wide and tall infrastructure for launch and landing facilities, habitat shielding, surface transportation, power generation, and communication. Orbital assembly infrastructure would include solar arrays, assembled radiators, backbone trusses for observatories, and habitats (I could probably think of more). Take a look at our NASA projects including the Tall Lunar Tower, Armadas, and Precision Assembled Space Structure for the direction we have gone so far.

Chinese Satellite Successfully Tests 3D-Printed Storage Tank in Orbit   The China Aerospace Science and Technology Corporation (CASC) has achieved a significant milestone with the successful in-orbit operation of a pioneering 3D-printed storage tank on the Tiandu-2 satellite. This event marks the first time a 3D-printed component of this kind has been used aboard a Chinese satellite, underscoring a major advancement in aerospace technology. The innovative cold propulsion system equipped on Tiandu-2 played a critical role by providing high-precision orbital attitude control during its mission in lunar orbit. This system is especially notable as it represents the first operational deployment of the liquid ammonia cold air micro-propulsion system designed for deep-space exploration tasks. The design and implementation of the storage tank as a key component of the satellite's propulsion system were paramount. It required high precision in its formation to ensure no leaks and durability to withstand the rigors of space. Its successful application is credited to the advanced 3D printing technology that allowed the CASC development team to intricately connect internal components, significantly cutting down the development cycle and associated costs. Moreover, the implications of this technological feat extend beyond immediate mission successes. The use of 3D printing in satellite construction presents a transformative approach for manufacturing in space, where the ability to produce complex components on demand could revolutionize future missions and space habitation. The launch of Tiandu-2, along with Tiandu-1 and the new relay satellite Queqiao-2 on March 20, represents a comprehensive expansion of China's capabilities in space communication and navigation technology. These satellites play a crucial role in China's broader strategy to enhance its infrastructure in space, ensuring robust communication links and precise navigation support for various missions. As the aerospace community continues to observe the performance of these newly deployed technologies, the success of the 3D-printed storage tank offers promising prospects for future applications in space exploration and satellite technology.

RS-25 engines certified for future Artemis missions after long testing program. by Clarence Oxford - Los Angeles CA (SPX) L3Harris Technologies and Aerojet Rocketdyne have concluded a comprehensive series of development and certification tests for the RS-25 engine, confirming its readiness for upcoming Artemis missions, starting with Artemis V. These tests were carried out at NASA's Stennis Space Center, involving a total of 45 development tests and 24 certification tests. The RS-25 engines, crucial for the propulsion of NASA's Space Launch System (SLS), have undergone significant upgrades to meet the needs of future Artemis missions. Originally used in NASA's Space Shuttle Program, these engines are being repurposed with modern enhancements for the SLS. The first four SLS missions will use refurbished RS-25 engines, while subsequent missions will incorporate newly built engines. Mike Lauer, RS-25 program director at Aerojet Rocketdyne, shared insights on the transition: "At the end of the Space Shuttle Program, NASA had 16 engines remaining, sufficient for four SLS flights. For subsequent missions, our objective was to modernize the RS-25 to enhance affordability and performance without compromising its proven reliability." The modernized RS-25 engines will operate at 111% of their rated thrust level, an increase from the 104.5% during the shuttle era and 109% for the initial Artemis missions. This enhancement reflects significant advancements in engine design and manufacturing. Significant improvements include the adoption of 3D printing techniques, specifically in the production of the Pogo Accumulator Assembly-a vital component for stabilizing the rocket during flight. This method has reduced system welds by 78%, demonstrating the viability of 3D printing for other engine parts. Currently, over 30 components of the new RS-25 engines utilize 3D printing technology. Another major advancement is in the Main Combustion Chambers (MCC), where Hot Isostatic Pressing (HIP) has been employed. This technique uses high pressure and heat to create durable bonds between engine components, capable of withstanding extreme temperatures and pressures. This process not only improves the durability and reliability of the engines but also significantly reduces both cost and production time. https://lnkd.in/dw885_TP

CHEAPER SPACE FLIGHTS DRIVING SPACE COMMERCIALIZATION 🚀 💰 Insightful graphic from the Center for Strategic and International Studies (CSIS) , showing the "The Cost of Space Flight" between 1960 to the present, where costs have dropped from about $51,000/kg (Space Shuttle) to around $2720/kg (Falcon Heavy). Clearly, SpaceX has been at the forefront of innovation to rethink the technology, reusability (over ten times reuse per rocket), and refurbishment of rockets. Now with SpaceX's recent #Mechazilla (grabbing the rocket as it returns to its launch pad), the drive towards the full commercialization is ON. Other advancements driving the costs of space flight include: 👉 Advanced Materials & Manufacturing: stronger, lighter materials (such as carbon fibre composites), and advanced aluminium-lithium alloys have reduced spacecraft weight. 3D printing has also helped to create cheaper rocket parts quyicker, especially for more complex designs. 👉 Vertical Integration: SpaceX design, manufacture their own rockets and spacecraft, eliminating third-party contractors and increasing control of their supply chains. 👉 Standardization, modularization and mass production of rocket parts have allowed for better economies of scale. 👉 Improved launch cadence through optimized ground operations allows for better utilization of launch infrastructure and personnel, reducing costs per launch. 👉 Automation: automated systems for launch sequence management, payload integration, and pre-flight checks reduce the need for manual labor and potential human error, leading to faster launch timelines. 👉Advanced data analysis tools to monitor rocket health, identify potential issues before they become critical, and optimize maintenance schedules can prevent costly delays and repairs 👉 Advancements in Propulsion Technologies: more efficient fuel types, better engines, and better reliability.
