Future NASA architectures have baselined cryogenic propulsion systems to support lunar missions and ultimately future missions to Mars. NASA has been investing in maturing CFM active and passive storage, transfer, and gauging technologies over the last decade plus primarily focused on ground development with a few small- scale microgravity fluid experiments. Recently, NASA created a Cryogenic Fluid Management (CFM) Technology Roadmap identifying the critical gaps requiring further development to reach a technology readiness level (TRL) of 6 prior to infusion to flight applications. To address the technology gaps the Space Technology Mission Directorate (STMD) strategically plans to invest in a diversified CFM portfolio approach through ground and flight demonstrations, collaborating with international partners, and leveraging Public Private Partnerships (PPPs) opportunities with US industry through Downloaded by Michele Dominiak on December 23, 2020 | http://arc.aiaa.org DOI: 10.2514/6.2020-4000 the Tipping Point and Announcement of Collaborative Opportunities (ACO) solicitations.

E-mail: [email protected] ABSTRACT Selecting liquid methane as fuel is a prevailing trend for recent rocket engine developments around the world, triggered by its affordability, reusability, storability for deep space exploration, and prospect for in-situ resource utilization. Given years of time required for acquiring a new rocket engine, a national-level R&D program to develop a methane engine is highly desirable at the earliest opportunity in order to catch up with this worldwide trend towards reusing launch vehicles for competitiveness and mission flexibility. In light of the monumental cost associated with development, fabrication, and testing of a booster stage engine, it is strategically a prudent choice to start with a low-thrust engine and build up space application cases. -
ESPA Ring Datasheet
PAYLOAD ADAPTERS | ESPA ESPA THE EVOLVED SECONDARY PAYLOAD ADAPTER ESPA mounts to the standard NSSL (formerly EELV) interface bolt pattern (Atlas V, Falcon 9, Delta IV, OmegA, Vulcan, Courtesy of Lockheed Martin New Glenn) and is a drop-in component in the launch stack. Small payloads mount to ESPA ports featuring either a Ø15-inch bolt circle with 24 fasteners or a 4-point mount with pads at each corner of a 15-inch square; both of these interfaces have become small satellite standards. ESPA is qualified to carry 567 lbs (257 kg), and a Heavy interface Courtesy of NASA (with Ø5/16” fastener hardware) has been introduced with a capacity of 991 lbs (450 kg). All small satellite mass capabilities require the center of gravity (CG) to be within 20 inches (50.8 cm) of the ESPA port surface. Alternative configurations can be accommodated. ESPA GRANDE ESPA Grande is a more capable version of ESPA with Ø24-inch ports; the ring height is typically 42 inches. The Ø24-inch port has been qualified by test to Courtesy of ORBCOMM & Sierra Nevada Corp. carry small satellites up to 1543 lb (700 kg). ESPA ESPA IS ADAPTABLE TO UNIQUE MISSION REQUIREMENTS • The Air Force’s STP-1 mission delivered multiple small satellites on an Atlas V. • NASA’s Lunar Crater Observation and Sensing Satellite (LCROSS): ESPA was the spacecraft hub for the LCROSS shepherding satellite in 2009. • ORBCOMM Generation 2 (OG2) launched stacks of two and three ESPA Grandes on two different Falcon 9 missions and in total deployed 17 satellites. -

Hi-Rel Solutions for Space Launch Vehicles a Single Network for All
© Airbus Safran Launchers 2016 © A Single Network for All Data Traffic Hi-Rel Solutions for Space Launch Vehicles www.tttech.com/space We are delighted that our network solution based on Deterministic Ethernet is providing a very powerful platform “ simplifying the electronic architectures of launch vehicles worldwide! Georg Kopetz, Member of the Executive Board, TTTech Computertechnik AG ” Over the last 25 years, space launch vehicle designs have utilized several different solutions for their on-board data handling. For the safety-critical command and control data, the very robust MIL-1553 bus served as a standard solution, originally designed as a military avionic data bus. For redundancy purposes, this widespread standard enforces two MIL-1553 buses running in parallel. This fact creates the first challenge, namely managing redundant fieldbuses in software and in parallel separate channels for additional data, e.g. telemetry. The second challenge arises from increasing data rates: MIL-1553 is limited to 1 Mbit/s, while there actually is both a need for higher control data rates and an interest in new types of sensors like video cameras. Adding more field buses would be possible, but would increase both weight and software complexity as well as qualification efforts. Finally, despite the need for higher bandwidth and a simplified network, no system cost increase can be tolerated, as in recent years the market for launch vehicles has become extremely competitive. This has led launch vehicle manufacturers worldwide to look for automotive or industrial solutions in order to reduce the cost of the electronics used throughout their vehicles. © Airbus Safran Launchers 2015 After several years of research funded by the ► French space agency (CNES) and afterwards by PROJECT ▼ the European Space Agency (ESA), architectures Launcher avionics A GLANCE AT based on TTEthernet are considered a great fit ► CHALLENGE for launch vehicles. -

Askeri Lojistikte Uzay Çağı Başlıyor Mu?
Askeri Lojistikte Uzay Çağı Başlıyor mu? zay alanında 60 yıldan fazla zamandır süren insan faaliyetleri, dünyadaki yaşam kalitesini artıran toplumsal faydalar üretti. Uzay araştırmalarının zorlukları, yeni bilimsel ve teknolojik bilgileri ateşleyerek, inovasyonun temel kaynaklarından biri oldu. Uzay araştırmaları, malzeme, enerji üretimi Uve enerji depolama, geri dönüşüm ve atık yönetimi, gelişmiş robotik, tıp ve medikal teknolojiler, ulaşım, mühendislik, bilgi işlem ve yazılım gibi alanlarda dünyaya anında fayda sağladı ve sağlamaya devam edecek. Bu alanlardan biri de roket teknolojisi… Uzay ekonomisinin lokomotifi olan fırlatma sektöründe son yıllarda büyük bir değişim yaşanıyor. Yerden fırlatmalı katı yakıtlı roketlerin maliyetini azaltma arayışları, yeniden kullanılabilir fırlatıcı sistemlerinin geliştirilmesine kapı araladı. Özel uzay şirketlerinin geliştirdiği yeniden kullanılabilir roketler, uzay çalışmalarının maliyetlerini azaltıp daha fazla oyuncunun uzayın olanaklarından yararlanmasının önünü açıyor. Yakın gelecekte yeniden kullanılabilir roketler yeryüzünde de bir ulaşım aracı hâline gelebilir. Örneğin ABD Hava Kuvvetleri, bu roketleri çatışma alanlarına veya insani yardım ihtiyacı duyulan bölgelere lojistik destek sağlamakta kullanmak için harekete geçti. ABD Uzay Kuvvetleri ile birlikte yürütülen Roket Kargo (Rocket Cargo) projesi1, geleneksel askeri kargo uçakları ile saatler hatta günler alabilecek 30 ila 100 ton arasındaki sevkiyatları yeniden kullanılabilir roketlerle 90 dakika2 içinde Dünya’nın herhangi bir noktasına -
