Robert Lightfoot

President of LSINC Corporation, Former Acting NASA Administrator
Topic: Becoming a Risk Leader

Abstract: In today’s ever changing world with new technology, how do we adjust our risk acceptance thinking?  Striking the appropriate balance between “we’ve always done it that way”, which often came from a hard earned lesson, and embracing something new, along with the associated risk it may bring, takes leadership. Understanding the key aspects of  “risk management” and “risk leadership” will help decision makers as they face the opportunities and challenges associated with using new technology within their current risk environment

Marshall Smith

Director Cross-Program Systems Integration, Exploration Systems Division, NASA
Topic: NASA’s Human Exploration Systems – SLS, Orion, EGS and Gateway

Abstract: Space Policy Directive 1, released in December 2017, calls for NASA to lead an innovative and sustainable program of exploration with commercial and international partners to enable human expansion across the solar system, including the return of humans to the Moon for long-term exploration and utilization followed by human missions to Mars and other destinations. NASA’s implementation of SPD-1 focuses on eight Strategic Principles, including fiscal realism, leveraging commercial and international partnerships, architectural openness, and continuity of human spaceflight. These principles inform a synergistic path back to the lunar surface, leveraging research and sustainable capabilities demonstrated on the International Space Station, the results from robotic lunar orbiters, an evolving robotic lunar surface capability leading to human-class landers, crew and large exploration payload access to cislunar space using the Space Launch System and Orion spacecraft, and building sustainable infrastructure around the Moon in the form of the Gateway. Gateway will serve as an exploration and science outpost in a novel near-rectilinear halo orbit around the Moon, composed of modules and services provided by U.S. industry and domestic commercial and international partners, and assembled using the SLS and Orion spacecraft. The first module, a Power and Propulsion Element, scheduled for launch on a partner-provided commercial rocket in 2022, will provide 50 kilowatts of power, communications, and attitude control using scaled up, commercially-proven xenon propellant technology. U.S. habitation development will build on partnerships already underway as part of the NASA NextSTEP initiative. Ultimately, Gateway will serve as a node for sustainable exploration of the area around the Moon and across all the lunar surface, in preparations for ambitious human missions to Mars and beyond.

Roy H. Olsson III

Program Manager, Microsystems Technology Office (MTO), DARPA
Topic: Zero and Near-Zero Power Sensors and RF Receivers for Persistent Sensing and Communication in Energy Starved Environments

Abstract: The DARPA Near Zero Power RF and Sensor Operations (N-ZERO) program seeks to overcome the power limitations of persistent sensing by developing wireless, event-driven sensing capabilities that allow physical, electromagnetic, and chemical sensors to remain dormant—effectively asleep yet aware—until an event of interest awakens them. State-of-the-art (SOA) sensors use active electronics to monitor the environment for such external triggers.  The power consumed by these electronic circuits either limits the sensor lifetime to unacceptable levels, often as short as days, or requires large batteries to maintain operational persistence. In contrast, N-ZERO seeks to exploit the energy in signal signatures to detect and classify attention-worthy events, such as the presence of a particular machinery type or radio communications protocol, while rejecting noise and interference.  This presentation will discuss the components, architectures and classification performance of wake-up sensors and radio receivers developed under the N-ZERO program.  The discussion will include both Zero power sensors for the processing and detection of acoustic, inertial, seismic, infrared and chemical signatures and sub-20 nW sensors for the processing and detection of RF waveforms and more complex, time-varying acoustic events.  N-ZERO technology is predicted to extend the lifetime of wireless sensors operating from small batteries from days to years under many operational scenarios.  The Zero power sensors emerging from the program, which are readily interfaced with passive wireless antennas and can intelligently sense without a battery, are likely to find crossover use in harsh environment applications that experience high levels of temperature, shock, and radiation that inhibit the use of conventional batteries and electronics.

Habib Rashvand

University of Warwick, U.K.
Topic: Smart Sensor Networking for Extreme Environments from Underground to Space: Properties, Challenges, and Industrial Paradigms

Abstract: Today’s sensor technology stemmed from a few centuries old development of crude measurement devices, which we have used them then enabling our systems to reveal the unknown or changing properties of a medium, a field, or an environment. As we were moving beyond the second global technological revolution the sensor technology began to thrive upon the energy requirements of the physical world, and automation into new electronic systems when we saw the rise of ‘transducers’ converting one form of energy to another.  Then, a few decades ago with the advent of information technology we found some form of using, handling, and manipulating some information at the tip of every device signaling the abundance of information and data processing when we celebrated rise of the smart sensors where an ultimate conversion capability that any form of energy associated with the observing activities and properties being translated into usable data.

At the turn of century, a new magical moment of mobility highlighted more effective use of smart sensing as the low cost wireless technology began to spread to every corner of the earth and beyond. This raised greater hopes for finding much better engineering solutions and interactive applications in all aspects of life and associated industrial activities far greater than ever before promising many new adventures including a better quality of life, adopting lightweight robotics, and promoting advanced automation and miniaturization across the industries towards higher productivity, greener world, and saving lives through a better understanding of the natural and man made disasters.

It did not take long to develop useful variants of wireless sensor networks (WSN) for higher impacts and creation of smart environments (accessible, communicative, and somehow intelligent) enabling ad hoc style energy efficient, agile, and dynamic clustering and networking capabilities. Unfortunately, this was not the end of the story for smart sensors. Being mostly concentrated in the convenient areas over the surface of the earth also known as terrestrial environments, also called conventional environments, we have been enjoying an easy ride.  It has been progressive and encouraging but not sufficiently enough challenging.  That is, when we move away from our terrestrial comfort zone towards the challenging extreme environments such as space, underwater, and underground, or harsh environments such as organic, industrial, and transportation then the scale of penetration for revealing the unknown properties of such environments we then realize the deployment of smart sensors requires a very different scale of challenges.

In such places not only we do not have an easy access to our devices our systems also behave differently with different requirements and new limitations even for the very basic operational functions such as cost, energy, connectivity, and maintenance.  In some cases we may need to go beyond the conventional wireless (FSO, acoustic, magnetic, seismic) and adopt mixed and more complex technologies (e.g., surface, guided, fiber, and power-line). We need to adopt specific topological configurations using advanced platforms, agent technologies, and new generations of unmanned automated vehicles (UAV).

We also may need to adopt more dynamic operations, where: (a) an interactive deployment may cater higher success rates and stronger sustainability; (b) use of interactive robotics and intelligent devices to empower a better manipulation of the environment; and (c) new generation of ‘platform’ for adopting the decentralized control under creation of higher trust for enabling more local functions for higher penetration and lower maintenance requirements.

This presentation carries a powerful message: ‘with every challenging achievement steps in the extreme environments comes a potential/prospect of initiating a new historical trend and to trigger a whole new technological paradigm’.

Amitabh Mishra

US Army CERDEC / University of Delaware
Topic: Communication in Extreme Environments – Recent Advances

Abstract: Early examples of extreme wireless communications are DARPA’s next generation Internet initiative known as InterPlanetary Network (IPNs) in 1998 created with the aim to define a communication system together with Internet like services across Inter Planetary distances in support of deep space exploration which led to its subsequent generalization as Delay Tolerant Networks (DTN) by Internet Engineering Task Force (IETF) in 2002. DTN is an overlay network that supports interoperability among networks by accommodating long disruptions and delays within and in-between. Even tough DTN was developed for IPNs it saw more relevance on earth where disruption tolerance was and continues to be a critical need. DTN architecture consists of network of internets each characterized by Internet like connectivity within but with provisions for occasional communication opportunities among them. Occasional communication opportunities concept blossomed into a new networking area known as “Opportunistic Networks (ON)” which found successful applications in wild-life monitoring, sensor networks, DakNet and others.

Store and Forward is the underlying theme for assured communication in IPNs, DTNs, and ONs which ensures reliable delivery of messages in the network, but with unbounded delays. However, there have been recent advances in reducing the network latencies, and several techniques have emerged that allow for faster recovery from disconnections, graceful disruption tolerance, and reliability enhancements by controlled losses. In this talk, I will talk about these emerging techniques such as selective redundancy for improved delivery over lossy links, braided back pressure forwarding, link adaptation and route management algorithms and others.

David Israel

NASA Goddard Space Flight Center’s Exploration & Space Communications Projects Division Architect
Topic: A Space Mobile Network

Abstract: The Space Mobile Network (SMN) is an architectural framework that shifts the traditional spacecraft communications focus from point-to-point links to a network user and provider model. The key features of SMN include standard network-layer services supported by high-availability access links, high-performance access links, and responsive service scheduling. The space communications user’s requirements differ from those of the traditional terrestrial network user. SMN allows for the phased implementation of a provider network, meeting those requirements while providing spacecraft users with an interconnectedness and link access experience analogous to that of a terrestrial mobile network user.

Simone D’Amico

Space Rendezvous Laboratory, Stanford University
Topic: Advances in Autonomous Guidance, Navigation and Control for Miniaturized Distributed Space Systems

Abstract: Two key trends are revolutionizing the way humans conduct spaceflight, namely, the miniaturization of satellites (e.g., micro- and nano-satellites) and the distribution of payload tasks among multiple coordinated units (e.g., formation-flying, on-orbit servicing, fractionation, swarms). The combination of these approaches promises breakthroughs in space science (e.g., imaging of earth-like planets, characterization of gravitational waves), remote sensing (e.g., synthetic aperture radar interferometry, aeronomy, gravimetry), and space exploration (e.g., lifetime extension, assembly of structures, space debris removal).

Irrespective of the specific application, future miniature distributed space missions require a high level of autonomy to maintain and reconfigure the relative motion of the participating vehicles within the prescribed accuracy and range of operations. Especially on small spacecraft, these requirements are hard to meet due to the limited resources, and the chief goal of current research and development is to pave the way for the autonomous Guidance, Navigation, & Control (GN&C) of “self-driving nanosatellites”.

Leveraging the author’s contributions to the most recent satellite formation-flying and rendezvous missions in low earth orbit (TanDEM-X, PRISMA, BIROS), this presentation addresses the astrodynamics and GN&C algorithms under developments to enable a new class of space instruments. A novel low-cost mission concept developed by the author is introduced, the so-called miniaturized Distributed Occulter/Telescope (mDOT). mDOT consists of two small formationflying satellites precisely positioned in high elliptical orbit to directly image exozodiacal dust and exoplanets. Finally, the high-fidelity hardware-in-the-loop virtual reality and physical testbed under development at Stanford for the verification of the new GN&C algorithms is presented.

Biography: Simone D’Amico is an Assistant Professor of Aeronautics and Astronautics at Stanford University. He is founder and director of the Space Rendezvous Laboratory (SLAB). He is a Terman Faculty Fellow of the School of Engineering and Satellite Advisor of the Student Space Initiative (SSI), the largest Stanford’s undergraduate organization. He holds a Ph.D. in aerospace engineering from the Technical University of Delft (The Netherlands) and received his B.S. and M.S. degrees from Politecnico di Milano (Italy).

Prior to joining Stanford in 2014, Dr. D’Amico was at the German Space Operations Center (GSOC) for 11 years. He gave key contributions to the design, development, and operations of spacecraft formation-flying and rendezvous missions such as GRACE (USA/Germany), TanDEMX (Germany), and PRISMA (Sweden/Germany/France) for which he received several awards. Also, he contributed to the design of the DEOS (Germany), PROBA-3 (Europe), and FireBird (Germany) formation-flying and rendezvous missions. D’Amico’s research aims at enabling future miniature distributed space systems for unprecedented science and exploration. His efforts lie at the intersection of advanced astrodynamics, GN&C, and space system engineering to meet the tight requirements posed by these novel space architectures. The most recent mission concept developed by Dr. D’Amico is a miniaturized distributed occulter/telescope (mDOT) system for direct imaging of exozodiacal dust and exoplanets. Dr. D’Amico is spearheading a gravitational space science and exploration program at Stanford based on multiple drag-free micro-satellites (MDSS).
