Featured Presentations Wednesday, October 4, 2017 – Coordinated by Starship Century Pete Worden, Executive Director, Breakthrough Initiatives Are We Alone?–Searching For Life in the Universe Dr. Worden will lead a talk on the work the Breakthrough Foundation is doing to help humanity investigate the possibility of life forms on other planets, and how scientists can get involved. The Star Shot initiative—a plan to send a spacecraft to another star system in the next 25 years—will be the main topic of the presentation. Dr. Worden will also discuss the foundation’s other major initiatives: Listen and Watch. Listen is the search for extraterrestrial intelligence using RF (1 GHz to 30Ghz) and visible light. Watch is the search for earth-sized planets in the habitable zone of nearby stars. Bio: Brig. Gen. Worden is the chairman for the Breakthrough Prize Foundation, where he runs the Breakthrough Initiatives. Previously, he has been Director of NASA’s Ames Research Center at Moffett Field, California, has held several positions in the United States Air Force and was research professor of astronomy at the University of Arizona, Tucson. He is a recognized expert on space issues – both civil and military. Worden has authored or co-authored more than 150 scientific papers in astrophysics, space sciences, and strategic studies.

He was named the 2009 Federal Laboratory Consortium Laboratory Director of the Year. Kevin L. G. Parkin, Parkin Research LLC Breakthrough Star Shot System Model and Trade Studies A constraint-based system model has been built to represent beam-driven relativistic sails. The model is solved by inference engine and uses 1-DOF RK45 trajectory integration nested within several bisection and golden section solvers in order to minimize the capital cost of the beam director while holding fixed the sail velocity at beam cutoff. A Goubau beam is assumed, the energy spillage of which is recalculated on every integration step, forming the core of the key tradeoff between beam director effective diameter vs. transmit power vs. sail diameter vs. beam duration. This key tradeoff is driven by user-provided technology figures of merit for beam director areal cost ($/m^2), transmit power cost ($/Watt) and energy storage cost ($/kWh) as well as sail areal density (g/m^2) and optical properties. Since March 2016, the system model has been used to conduct parametric trade studies for a 0.2c mission to Alpha Centauri, a 0.01c precursor mission to a closer objective and a 70 km/s ground-based vacuum tunnel test facility. The results from these trade studies are presented. Bio: Dr. Parkin is the Systems Director of Breakthrough Star Shot, founder of Parkin Research LLC and the inventor of the microwave thermal rocket. In 2005 he was awarded the Korolev Medal by the Russian Federation of Astronautics and Cosmonautics for his ground-breaking work in microwave thermal propulsion. In 2007, Dr. Parkin founded the Mission Design Center (MDC) at NASA Ames. From 2009 to 2015, he was a Research Faculty member at Carnegie Mellon Silicon Valley. In this role, he served as Principal Investigator of a $5M NASA-funded project to conduct innovative research to implement a sustainable and extensible vision for space exploration in the long term. From 2012-2014 he additionally served as Principal Investigator and Chief Engineer of a $3M DARPA-instigated project to build a small millimeter-wave thermal rocket and launch it. This resulted in the first millimeter-wave absorbent refractory heat exchanger, the first millimeter-wave thermal rocket, and the first high power cooperative target millimeter-wave beam director. These elements were combined to achieve the first millimeter-wave thermal rocket launch in early 2014. He is a member of the Institute of Physics (IOP) and holds an M.Phys. from the University of Leicester (1999), an M.S. from Caltech (2001) and a Ph.D. from Caltech (2006). Robert Fugate The Star Shot Propulsion System The key concept for going to the stars in the Star Shot Project is to minimize the mass of the spacecraft by leaving the apparatus that propels the spacecraft on Earth. The force that accelerates the payload is light pressure generated by a laser system producing a controllable, coherent beam of light having an average power of the order of 100 GW. A 1-gram mass payload would experience an acceleration about 60,000 gees when subjected to the radiation pressure from this system (assuming imperfections). This talk addresses the many challenges confronting us in conceiving, designing, building, and operating such a propulsion system. Chief among these are developing a plan to coherently combine many millions of laser beams at the sail target in the presence of laser phase noise, large optical path length differences, and atmospheric refractive index fluctuations caused by turbulence, while maintaining a specified irradiance profile on the sail with sub nanoradian pointing jitter as it travels from high earth orbit to a distance equivalent to ten times the range to the Moon, all in a few hundred seconds. Bio: Dr. Robert Q. Fugate is internationally recognized as the first to demonstrate the concept of laser guide star adaptive optics and to develop and apply needed technologies to make the concept practical on large ground-based telescopes. This technology allows researchers to overcome the limitations on image resolution set by the Earth’s atmosphere. Dr Fugate spent over 35 years in the Air Force Research Laboratory and retired as the Senior Scientist for Atmospheric Compensation in 2006. He created the Starfire Optical Range as the premier research organization in the DoD for correcting atmospheric effects on the propagation of light. He championed the transition of this technology from DoD to the astronomy community. From early 2006, he was the Senior Technical Advisor on the staff of New Mexico Tech and retired with Emeritus status at the end of 2011. He now serves as a part-time consultant, speaker, and advisor to the Air Force and other US Government agencies and private organizations. His latest endeavor is serving on the advisory board for Breakthrough Star Shot and as Chairman of the Laser Subcommittee. He is a member of the National Academy of Engineering, has published over 100 papers and book chapters, presented dozens of invited talks, served on numerous international astronomy and telescope committees, and has received many honors. James Benford, Microwave Sciences Our First Starships: Sails & Payloads for Star Shot Star Shot reduces the sail mass down to about a gram and sail scale to a few meters. The acceleration is driven by lasers with total power of 10-100 GW; accelerations are 10,000 100,000 gravities. Acceleration times are about 1-10 minutes. Constructing a laser light sail sufficient to propel a one-gram class spacecraft to 0.2c within a few decades using a laser beam director of approximately one-kilometer scale with a beam power of 10’s of GW requires thin and light-weight materials, perhaps metamaterials, meaning fabrication of meter-scale sails no more than a few hundred atoms thick. The material must be light enough yet highly reflective. Properties that influence material choice and fabrication, are its reflectance, absorptance and transmittance, tensile strength and areal density. Stability of he sail on the beam is influenced by sail shape, beam shape and the distribution of mass, such as payload, on the sail. The laser system interacts with the sail through its power density distribution on the sail, duration of the beam, width of the beam, pointing error of the beam as well as its pointing jitter.

He is an IEEE Fellow and an EMP Fellow. David Messerschmitt, Professor Emeritus of Electrical Engineering and Computer Sciences, UC Berkeley Data Return from Star Shot Probes: Live from Alpha Centauri! Returning scientific data from a Star Shot mission will be challenging due to many factors, including limited available energy, transmit and receive antennas, pointing accuracy, and speed. This talk examines an optical downlink communicating image data. Available energy has to be beneficially allocated among attitude control, processing, and communications functions. The profile of the available power varies widely during and after an encounter. Especially relevant is the rapidly changing distance to a target star, and the impact of this distance on available solar energy. Based on known fundamental limits, the maximum total returned data is estimated for a set of alternative assumptions. For best-available coding algorithms, energy-balance tradeoffs between processing for source and channel coding and transmitted optical power are considered. For the benefit of audience members not well versed in communications theory, we include a brief tutorial on the fundamental limits to image coding and communications. This talk reports on joint work with Philip Lubin of the University of California at Santa Barbara and Ian Morrison of Swinburne University Australia, and draws heavily on near-Earth optical communications research at Jet Propulsions Laboratory and elsewhere.

TED Talk: Rocket Scientist: Making Space Pay and Having Fun Doing It Friday, October 6, 2017 – Coordinated by TVIW Slava Turyshev, NASA Jet Propulsion Laboratory Direct Miltipixel Imaging of an Exo-Earth with a Solar Gravitational Lens Telescope Nature has presented us with a very powerful “instrument” that we have yet to explore and learn to use. This instrument is the Solar Gravitational Lens (SGL), which results from the ability of the gravity field of the Sun to focus light from faint, distant targets. In the near future, a modest telescope could operate on the focal line of the SGL and, using the enormous magnification power of the Lens, could provide high-resolution images and spectroscopy of a habitable exoplanet. We discuss the imaging properties of the SGL, when the image occupies many pixels in the region near the optical axis. We discuss a mission to the SGL focal region that could provide us with direct, multi-pixel, high-resolution images and spectroscopy of a potentially habitable Earth-like exoplanet. Based on our initial studies, we find that such a mission could produce (1,000×1,000) pixels images of “Earth 2.0” at distances up to 30pc with spatial resolution of ~10 km on its surface, enough to see its surface features. We address some aspects of mission design and spacecraft requirements, as well as capabilities needed to fly this mission in the next two decades.

Congressman John Culberson, R-TX Washington Perspectives on Interstellar Research Bio: As Chair of the House Commerce, Justice, Science, and Related Agencies (CJS) Appropriations Subcommittee, which funds NASA, the Congressman is focused on ensuring that NASA receives the funding and guidance necessary to maintain US leadership in space. He supports additional funding for NASA and believes it is crucial for the agency to have a clear vision that is driven by science and inspires our young people to study science and mathematics. The Space Launch System heavy-lift rocket and Orion multi-purpose crew vehicle will be critical components of our capability to return to the moon or lunar orbit, to reach Mars, and to go beyond. He authored the Space Leadership Preservation Act to make NASA more professional and less political by establishing a long-term NASA Administrator who overlaps presidential administrations, creating a board to drive the vision for NASA exploration, and allowing NASA to develop spacecraft using long term contracts. Congressman Mo Brooks, R-AL Washington Perspectives on Interstellar Research Bio: As the Representative for Alabama’s 5th Congressional District the Congressman represents the people of North Alabama (including the greater Huntsville aerospace community) and serves on three important committees: Armed Services, Science, Space, and Technology, and Foreign Affairs. After many years of White House neglect, Congressman Brooks has a renewed sense of optimism for the space program under the current Administration. Congressman Brooks strives to ensure that these programs remain on a steady path to success. He was excited to see the Trump Administration prioritize deep space exploration in its first year budget request, demonstrating that he has the full intention of challenging America’s space program to reach farther into space than ever before through the use of vehicles like the Space Launch System and Orion. Congressman Brooks knows that there is more work to do to ensure the preeminence of our nation’s space program. That is why he is committed to doing whatever is necessary to promote our nation’s space objectives via Congressional hearings, meetings, and letters to key appropriators, and will continue to monitor NASA’s progress on these critical programs.
