Chris Singer

Former NASA Deputy Chief Engineer & Marshall Spaceflight Center Engineering Director
Topic: The Engine of Possibility Accelerating Development

Abstract: As the universe expansion accelerates, the exponential pace of information continues to shrink and connect the globe in unexpected ways. New discoveries in physics, biology, geology, at the macro, micro, and nano level create more questions than answers. So, the confounding question in aerospace systems, why does new capability take twice as long to infuse as 25 years ago? While technology and tools are opening the path for new capability, solving this riddle requires a much deeper look in the mirror. Only a learning culture is able to embrace innovation, uncertainty, and boldly face the risk conundrum, while infusing hard-won experiences without over-controlling. Technologies like wireless sensing and power systems, additive manufacturing, structured light scanning and advanced analytical tools are re-shaping the entire product life cycle, from design, analysis, production, verification, and logistics enabling significant increase in performance and reduction (2-10X) in cost and schedule. Maximizing these technologies requires an open environment, able to temper experienced based rules with creativity, and breaking thru our natural human desire for control with the inspiration of possibility.

Dr. Fassi Kafyeke

Senior Director, Strategic Technology & Innovation, Bombardier Aerospace
Topic: The Growing Use of Sensors in Business and Commercial Jet Aircraft

Abstract: Bombardier is a manufacturer of planes and trains. In aviation, we develop, produce and support airplanes in the business, regional and commercial market. The presentation will discuss the growing impact of sensors technology on our operations and will discuss also our efforts to understand and document the particular environments into which long range high altitude aircraft typically fly. The use of sensors technology in aviation industry keeps growing, because sensors play a vital role in supplying information during flight. Aircraft safety relies on good operation of all systems, in any environment; and sensors have the major role of supplying vital information to the pilot about the flight. The majority of these sensors today are wired to the computers that perform signal analysis. Weight reductions and added flexibility can be achieved with wireless sensors but this can only be done once the integrity of the communication can be completely assured. Recent progress in data analytics and artificial intelligence has also increased the value of information that sensors located on various parts of the aircraft can provide. This can be used for passenger services, flight operations optimization and predictive maintenance of aircraft. At various altitudes, aircraft can be exposed to cosmic radiations coming from external galaxies above the sun. The exposure of electrical and electronic systems can lead to component failures. To further our understanding of this phenomena, Bombardier is conducting a Cosmic radiations flight measurement campaign, as part of a collaborative project with three Canadian universities and other industrial partners. Although this measurement campaign uses wired radiative Sensors, it is an example of a sensor investigation into the environments in which aircraft typically operates.

Dr. Sterling Rooke

Founder Brixon, Inc., & Director-Elect ISA Communications Division (2018-2019)
Topic: Translational Awareness: at the Nexus of Physics and Cyber-in-Space

Abstract: Reliability combined with measurement possibilities highlight ubiquitous wireless sensors as a tantalizing option for total system awareness. However, the ability of sensor systems to translate physical measurements into actionable information becomes even more challenging in extreme environments such as space. While factors such as co-existence in the wireless domain and anomaly rejection, have been presented by others, this presentation focuses on the interplay between physical measurements in an industrial system and cyber as an interlaced consideration. Recently, there was a notional discussion in the United States for creating a 6th military branch that will exclusively focus on the Space Domain, and by extension cyber-in-space itself. Satellites and instruments on orbit well be at the *nexus of physics and cyber-in-space*. Understanding the interplay between physical and cyber sensors is critical for the viability of orbital vehicles of the future.

Dr. Obadiah Kegege

NEN Development Manager, Exploration & Space Communications Projects Division, NASA /GSFC
Topic: User Needs and Advances in Space Wireless Sensing & Communications

Abstract: Decades of space exploration and technology trends for future missions show the need for new approaches in space/planetary sensor networks, observatories, internetworking, and communications/data delivery to Earth.  The “User Needs” to be discussed in this talk include interviews with several scientists and reviews of mission concepts for the next generation of sensors, observatories, and planetary surface missions.  These sensor nodes or instruments are envisioned to operate in extreme space environments, with advanced autonomy, whereby communication to Earth is intermittent and delayed.  In these scenarios, the sensor nodes would require autonomous networking capabilities in order to learn and adapt to the environment, collect science data, internetwork, and communicate.  Also, some use cases require the level of intelligence to manage network functions (either as a host), mobility, security, and interface data to the physical radio/optical layer.  For instance, on a planetary surface, autonomous sensor nodes would create their own ad-hoc network, with some nodes handling communication capabilities between the wireless sensor networks and orbiting relay satellites.   A section of this talk will cover the advances in space communication and internetworking to support future space missions. NASA’s Space Communications and Navigation (SCaN) program continues to evolve with the development of optical communication, a new vision of the integrated network architecture with more capabilities, and the adoption of standardized space internetworking protocols.  Advances in wireless communications hardware and electronics have enabled adaptive (DVB-S2, VCM, ACM, DTN, Ad hoc, etc.) protocols for improved autonomous wireless communication and network management.  Developing technologies to fulfill these user needs for wireless communications, standardized internetworking protocols, and enhanced autonomy will be a huge benefit to future planetary missions, space observatories, and manned missions to other planets.

Dr. Panagiotis Tsiotras

College of Engineering Dean’s Professor, Georgia Institute of Technology, Director of the Dynamics and Control Systems Laboratory, School of Aerospace Engineering, Georgia Institute of Technology
Topic: The Next Frontier: The Challenges in Developing Truly Autonomous Space Robots

Abstract: Several industry and government organizations are currently considering autonomous and semi-autonomous spacecraft robotic proximity operations as an enabling technology for several future space missions, such as on-orbit spacecraft inspection, surveillance, servicing, interferometry, formation flying, and many others. A crucial element of this technology is its ability to reliably perform autonomous relative pose estimation and tracking for robotic systems in orbit. Despite the tremendous recent advances in the field of ground robotics in terms of perception, learning, and control – mostly fueled by new AI algorithms and innovative computer hardware architectures where there are many difficulties that make similar implementations in a space environment much more challenging. These include, for example, harsh and rapidly changing illumination conditions (especially in LEO), long communication delays that limit human intervention in case of an emergency, severe resource (e.g., fuel, energy) constraints, much higher requirements for fail-safe operation, not to mention the physics themselves (Keplerian laws, momentum conservation constraints). The pace of new research to solve these challenges is hindered by the scarcity of suitable experimental platforms and methods to validate novel theories in a realistic space environment. In this talk, we will look at several aspects of these challenges, and offer some suggestions for potential remedies. We will present some results on spacecraft control under actuator and sensor failures and will focus on vision-based relative pose estimation, a fundamental problem in any robotic system. We will investigate both cooperative and non-cooperative vision-based scenarios, and provide experimental validation results using the 5dof spacecraft simulator facility at Georgia Tech.
