The Best 10 Days of the Year

Raj Rajkumar helps roll out the Flagstaff Festival of Science as he offers a glimpse into the near future of fully automated cars.

Friday, Sept. 21 • 7 p.m. W. L. Gore & Associates Keynote Presentation:

Self-Driving Vehicles: Accelerating into the Future Raj Rajkumar, Ph.D., Professor of Electrical/Computer Engineering

The power of artificial intelligence will likely take the driver’s seat in the very near future. World-renowned driverless car technology expert Raj Rajkumar will propel us down the road to a tomorrow of driverless vehicles as he shares the latest innovations from his General Motors-Carnegie Mellon Autonomous Driving Collaborative Research Lab. The presentation follows an interpretive dance performance by the NAU Community Dance Academy.

Accelerating into the Future with Driverless Cars Raj Rajkumar imagines a future where guardian angel robots help wheelchair-bound humans get in and out of bed, where companion robots keep the elderly and others living alone company, and where chauffeur robots become eyes for the blind as they escort them from Point A to Point B. “The field of Artificial Intelligence (AI) has been an exciting place to be,” says Rajkumar, a professor of electrical and computer engineering at Carnegie Mellon University. Especially since 2006. That’s when the U.S. military announced a contest to build a driverless car. Rajkumar was all in. “I’ve been working with General Motors since 2004. Then, our focus was on looking to make cars more intelligent, that they would at least help the human driver. That is what I was working on.” But DARPA, the Defense Advanced Research Projects 2

Agency, the research arm of the U.S. military, revved up the country’s automotive innovations with a driverless vehicle competition. In the DARPA Urban Challenge, teams were required to build an autonomous vehicle that could drive in traffic, merge, pass, park and maneuver through intersections for 55 miles. Four hours after the race began at the former George Air Force Base in Victorville, Calif., in November 2007, a car called, “Boss” was first to cross the finish line. Boss was the creation of Rajkumar and the Carnegie Mellon Team, Tartan Racing. That was the first time driverless vehicles mingled with both manned and unmanned traffic in an urban setting. “This launched the sequence of events in history leading us up to today,” he says. As the director of the General Motors-Carnegie Mellon

Autonomous Driving Collaborative Research Lab, Rajkumar has been working in advanced automotive technology for 15 years. He says the knowledge and the possibilities have raced far beyond that early competition. “When vehicles can drive themselves, accidents, injuries and fatalities can go down significantly;

one can be productive during commutes and when stuck in traffic; the elderly and the disabled will regain mobility options and their quality of life will up go up dramatically. That, he says, “is the potential of driverless vehicle technology.” Cameras and sensors, including radar and LIDAR, help driverless

cars navigate roadways and prevent collisions with other vehicles, buildings and pets. Rajkumar predicts fully automated cars in the U.S. are about 10 years away. “But, for specific locations like inside downtown Manhattan or countries like India or Vietnam, where traffic is very different, it’s going to take much longer than that.” Over time, he says, the social and economic benefits of driverless cars are enormous; however, he cautions that we aren’t there yet. “The market for driverless vehicles will be huge, perhaps several trillion dollars, that’s with a ‘t,’ every year. Therefore, there’s a lot of financial incentive for companies to create the perception that they are the leaders in the market. Meanwhile, the challenges are very real. It’s going to take more time to make sure the technology is reliable, so we as consumers need to remain cautious about the marketing campaigns and the hype created, and understand that this is a transformation, an evolution, and try not to adopt this too early, thinking the technology is more reliable today that it actually is.” Rajkumar grew up in South India, admiring science giants like Isaac Newton, Einstein, Charles Darwin and Thomas Edison. He came to the United States in 1984, when he was 21. Now, a giant himself in the world of advanced automotive technology, Rajkumar is rolling out the awardwinning Flagstaff Festival of Science as the W. L. Gore & Associates Keynote Presenter. His talk, “SelfDriving Vehicles: Accelerating into the Future,” is scheduled for 7 p.m., Friday, Sept. 21, in Northern Arizona University’s Ardrey Auditorium. The event is free; however, tickets are required and can be picked up ahead of time on a first-come, first-served basis at the NAU Central Ticket Office (nau.edu/cto; 928-523-5661).

Kīlauea Calls to Flagstaff Volcanologists

The ‘once-in-a-generation’ event has scientists studying glowing lava fountains, ash explosions and red hot rivers of molten rock By Greg Vaughan, Ph.D. Kīlauea Volcano, on the Big Island of Hawai’i, has been erupting continuously since 1983. But in the beginning of May 2018, a new eruptive episode began – in the middle of a neighborhood – and rapidly expanded into a flurry of volcanic activity. After several days of warning signs – buckling landscape, earthquakes, and steam escaping from new cracks in the ground – a new eruption commenced on May 3, in the Leilani Estates subdivision along Kīlauea’s Lower East Rift Zone (LERZ). Steaming cracks turned into fissures of erupting lava, cutting across roads and backyards. In the following days and weeks, what was once a boiling lava lake at Kīlauea’s summit drained away and transformed into a conduit for explosive eruptions, sending ash and toxic gases tens of thousands of feet into the air. Along the LERZ, dozens of fissures opened up and coalesced into an impassable barrier of lava more than eight kilometers (five miles) long. Minor lava spattering from fissures turned into roiling lava fountains hundreds of feet tall, sending rivers of molten lava burning across the landscape all the way to the ocean. Thousands of people were evacuated and hundreds of homes and other structures were consumed by lava. The Hawaiian Volcano Observatory (HVO), part of the U.S. Geological Survey’s Volcano Hazards Program, is tasked with


monitoring, investigating, and assessing hazards from active volcanoes and earthquakes in Hawai’i. Volcanologists communicate the findings to the public, emergency managers, and scientists. During an event such as this, HVO staff members go into 24/7 crisis response mode. They provide regular updates on the current volcano alert level, the aviation alert color code, explosive activity, ash fall, earthquakes, hazardous volcanic gas emissions, and the ever-changing locations of ground cracks, active fissures, and lava flows. During these times of volcanic crisis, volcano observatories call upon the greater USGS volcano science community for help. Whether it’s responding to media requests, or analyzing the abundance of satellite remote sensing data used for assessing and mapping volcanic hazards, or rotating in for on-site field work, scientists and technicians from all over the USGS – including Flagstaff – come together to help. USGS Flagstaff volcanologist and lava flow expert Elise Rumpf, Ph.D., is one of the field researchers who worked the night shift to keep track of the fierce activity. “It’s such an incredible experience. Studying volcanology,

you see videos of eruptions and you hear people’s account of them, but to actually be there and see lava that’s erupting, fountaining and going 100 or 150 feet into the sky is just remarkable,” she said. “There is just kind of a constant roar that comes from these fountains and, in some places, there are these steam bursts that were very, very loud. You could hear them for miles.” Rumpf has been studying Kīlauea’s Pu'u'Ō'ō Eruption for many years. She says it has taken a slow, steady journey to the sea, which is easy for researchers to access and study, much different from the latest activity. As a USGS Flagstaff volcanologist, I was also immersed in this eruption response by collecting and analyzing a firehose spray of images coming from remote sensing satellites and airborne platforms. In addition to NASA and USGS satellites, like ASTER and

Landsat 8, commercial satellite companies, such as DigitalGlobe, and foreign space agencies, such as the European Space Agency, also provide remote sensing resources that help us locate hazards and keep people safe. Kīlauea’s fierce 2018 activity is a once-in-a-generation scale event. For scientists like Elise and me, it is an incredible opportunity to make observations and measurements that will boost our understanding of volcanic processes and hazards, and help us learn more about the physics of how lava flows work: where they form, how they advance, how they interact with textures on the ground, and where magma is moving underneath. All the while, the human side of us tempers our scientific excitement with compassion and empathy for those who have been displaced, many of whom have lost their homes.

Hear the latest about the volcanic event from Greg and Elise at the Flagstaff Festival of Science special presentation, Kīlauea Eruption!, 3 - 5 p.m., Sunday, Sept. 23, at the Museum of Northern Arizona. Greg Vaughan is a Festival Board Member and USGS Volcanologist.

Gore recently launched new Gore® Automotive Vents that protect these sensitive electronic components from the elements. Gore automotive vents prevent buildup of heat and hazardous gases and protect against condensation, which can extend the reliability of related electronics.

W. L. Gore & Associates Technology Fuels Automotive Advancements By Jana Kettering

Flagstaff is a hub for Gore’s Medical Products Division — a place where the company engineers and manufactures medical devices that treat such complex conditions as aortic aneurysms, peripheral artery disease and heart defects. But did you know that Gore’s products also explore the depths of outer space, protect first responders from the elements, clean the air we breathe and ensure the performance of mobile electronics? Since its founding in 1958, the materials science company has created and launched innovations aimed at improving lives and industries. This year, as the Festival of Science gears up for the W. L. Gore & Associate Keynote Presentation with Raj Rajkumar, Ph.D., a leading expert in driverless vehicles, let’s take a closer look at how Gore is fueling ePTFE advancements in the automotive industry. 4

“In today’s vehicles, technology is taking the driver’s seat,” says Global Market Growth Leader from Gore’s Performance Solutions Division Mark Weier. “Gore helps the auto industry prepare for the future with solutions found anywhere from a car’s headlamp to the tail pipe.” Lately, there’s been particular buzz around autonomous driving, a concept that’s no longer science fiction. A variety of automotive components are moving us closer to this reality; for example, warning us if we veer out of a lane or come too close to another car. To meet the growing demands for this technology, Gore recently launched new Gore® Automotive Vents that protect these sensitive electronic components from the elements. Gore automotive vents prevent buildup of heat and hazardous gases and protect against condensation, which can extend the reliability of related electronics.

Gore’s vents are highly effective at blocking water, condensation and dirt — not just during sprays and splashes, but even during deeper roadway flooding. Although the vents are engineered specifically for use in smaller spaces, the airflow performance equals that of larger vents thanks to recent advances in GORE™ Membrane technology. “Our new vents address multiple challenges that arise in developing and sustaining advanced driving system components that are paving the way toward the future of driverless vehicles,” adds Weier. This future state of driving also became more tangible at the 2018 Olympic Winter Games in PyeongChang, where the South Korean Hyundai Motor Group showcased its latest autonomous vehicle, NEXO, which chauffeured international guests between the sports facilities. The SUV is not only a proof point for advanced

autonomous driving, but also for clean fuel cell technology. The non-autonomous version officially launched in Korea in March and features fuel cell technology from Gore, enabling the hydrogen powered vehicle to offer a yet unmatched driving range of 370 miles. The fuel cell creates electricity to power the vehicle and adds range when paired with a lithium ion battery. Gore’s technology facilitates a chemical reaction between hydrogen fuel and oxygen to power fuel cell electric vehicles and enable them to run without emitting pollutants. Gore’s technology facilitates a chemical reaction between hydrogen fuel and oxygen to provide the vehicle’s electric power. The only emission is water. Today, you can find GORESELECT® Membranes in a number of leading fuel cell cars. But Gore began developing fuel cell technologies more than 20 years ago — well before the commercialization of such vehicles. Gore Automotive Business leader Laura Keough describes this as a prime example of Gore’s commitment to taking a long-term view. “The fuel cell market has been in a research and development phase for a long time,” she says. “And, because we have been heavily involved in this phase, we have built up the knowledge, the technology, the expertise and the relationships needed to be successful as the industry evolves.” To learn more about Gore’s automotive technologies, explore the interactive map online at https:// www.gore.com/products/interactivecar or https://www.gore.com/ venting-applications

Native Students Picture Themselves as Astronomers By Todd Gonzales Lowell Observatory astronomers who have visited Navajo and Hopi schools have learned that a majority of the students perceive scientists to be male and not of their own Native culture. The observatory’s NavajoHopi Astronomy Outreach Program is designed to change that. The program began in 1996, through the efforts of Deidre Hunter, Ph.D., and her team. It seeks to connect an astronomer with a fourth through eighth grade class on the Hopi or Navajo nations. The astronomer visits the class several times a year to lead lessons and star parties. The culmination of the year is when the students come to Flagstaff to spend a night with the research telescopes at Lowell Observatory. The science lessons the astronomers would lead in the classroom are usually hands-on and not purposely aligned to any of the state and tribal standards. In early 2016, the Navajo-Hopi program took a different direction when Hunter asked some of the veteran teachers in the program to meet up and give Lowell Observatory

insights on improving the program. What came out of that meeting was a unanimous request to include multiple academic disciplines in a project based unit. The new curriculum would tie in reading, writing, math and culture with the science. To accomplish this new task, Lowell Observatory hired a certified teacher to begin curriculum development on the new multi-disciplinary lessons for fifth graders. The first unit was based on characteristics of the planets, which is a fifth-grade science standard. However, to include the students’ culture and other academic disciplines, students were tasked with creating an informational poster describing how life would be different living on another planet. It is hoped that this program is making a difference in how Native youth view themselves and their future in science education and careers.

Todd Gonzales is the master teacher at Lowell Observatory.

Local Youth Hope to Benefit Others in their STEM Careers

Flagstaff’s STEM City recently honored two local 18-year-olds who are pursuing higher education and careers in science and hope to make a difference in the lives of others: Wyatt Clark, a recent graduate of Flagstaff Arts and Leadership Academy; and, Sisilia Sinaga, a recent graduate of BASIS Flagstaff. Clark says he is grateful for the work of engineers, educators, programmers and scientists of all

sorts who developed technology that helped make learning easier for himself and others who are dyslexic. “That is why I love science, and that is why I dedicate every moment of my professional life to Science Technology Engineering Art and Mathematics (STEAM), because I know that the work I do, whatever that may be, will impact thousands of people who I will never know and will never know me. I am greatly humbled to have received the Flagstaff STEM Student of The Year award, the significance of which does not end at a trophy to place on my shelf, but acts as a constant reminder that for every advance in technology, a generation of people are given opportunities once thought impossible.” Clark has experience in robotics and an interest in rockets, telescopes, prosthetics, automated farming and renewable energy. He

By Bonnie Stevens

has worked as an intern for the U.S. Naval Observatory and is attending Northern Arizona University this fall as a mechanical engineering student in the honors program. Sinaga has always loved and been actively involved in STEM, especially math, computer science, and physics. “I love that science is complicated and full of unanswered questions, but there is nothing more satisfying than the process of solving a difficult problem and finding a solution, and even when one problem is solved, there are still so many other questions to learn about and solve.” Some of her favorite STEM activities during high school included competing with her school’s robotics club, writing code for artificial neural networks at the USGS, volunteering through STEM City to expose younger students to computer science, and programming on her own for fun. She is a freshman at

Northwestern University this fall, majoring in computer science. She hopes to use computer science to pursue robotics in graduate school and, along with her interest in business and entrepreneurship, create her own robotics startup that will benefit people. She is honored to receive the STEM Student of the Year award, and hopes that her activities and accomplishments can inspire other students to pursue STEM.

Retracing the Steps of Moonwalkers By Kevin Schindler

About 210 million people have visited the Grand Canyon since it was designated a national park nearly a century ago. While there, these pilgrims typically have found inspiration in the resplendent layers of rock. In the mid-1960s, local geologists realized that they could draw on such revelations to stimulate a group of jet pilots to want to learn about geological principles, information they could use on future flights. But these flights wouldn’t visit foreign cities or countries, but a foreign world. The pilots were Apollo astronauts, and, under the guidance of the geologists that were working on behalf of NASA, they hiked into the Grand Canyon in preparation for their missions to the Moon. In fact, all 12 of the astronauts who flew around the Moon, and 11 of the 12 who set foot on the lunar surface, participated in 14

these training exercises. The one Moonwalker not accounted for? That would be Harrison “Jack” Schmitt, who was a geologist by trade and so didn’t need further training in the Grand Canyon. Schmitt was the only scientist to walk on the Moon and, in fact, was working at the United States Geological Survey in Flagstaff when he was chosen to be one of NASA’s scientist-astronauts. This astronaut training transpired over three trips. The first was on March 5-6, 1964, and consisted of 18 astronauts, including future Moonwalkers Neil Armstrong, Buzz Aldrin, Alan Bean, Alan Shepard, Dave Scott and Gene Cernan. A week later, future Moonwalkers Pete Conrad and John Young were part of a group of 11 to visit. Finally, on June 2-3, 1966, a group of 19 that included future Moon walkers

Edgar Mitchell, Charlie Duke and Jim Irwin made the trek into the Canyon. All three hikes followed the same plan. The astronauts flew into Flagstaff and then drove with geologists to the Canyon. After a briefing at the Yavapai Geology Museum, the group headed to the trailhead of South Kaibab Trail and made broad-scale observations of the Canyon. They then broke up into small groups, with two or three astronauts and a geologist in each group, and began hiking down, studying the general superposition of rock layers, as well as more detailed features such as the fossils of the Kaibab Limestone and cross bedding in the Coconino Sandstone. While the geologists knew these particular types of rocks,

not to mention the fossils, would not be on the Moon, they nevertheless found their characteristics useful in teaching largescale geological processes. Plus, they had the undivided attention of the astronauts; teaching geology to a group of pilots with limited interest in geology was much easier to do in the grandeur of the Grand Canyon than in a classroom. The hikes turned into crash courses in geology, with the astronauts each carrying and using geology hammers, hand lenses, compasses, field notebooks and other tools of the trade. The groups slowly descended the South Kaibab, periodically stopping to examine rock crystals or study rock charts. They finally made it to the bottom and Phantom Ranch, where they had to survive the annoyance of skunks and rustic sleeping conditions. The next morning, they hiked up Bright Angel Trail, with the astronauts recalling what they had learned the previous day. Many rode mules out from Indian Gardens, though some of the more driven astronauts, including the hypercompetitive Alan Shepard, insisted on hiking out. The Grand Canyon experience proved beneficial for the astronauts, helping them gain an appreciation for the vastness of geologic time and the magnificent forces involved with forming and, eons later, exposing rocks.

On September 29 at 7 p.m., Schindler, Lowell Observatory historian, will give a presentation at Riordan Mansion about these long forgotten training hikes at the Grand Canyon. To put this program together, he retraced the path the astronauts took, re-photographing many of the sites within the Canyon that they visited. The presentation will thus be part overview of training activity, part comparison of how the Canyon looks today versus during the astronaut training more than 50 years ago. For instance, a dead tree at the base of O’Neill Butte— evident in a picture from one of the 1964 training hikes—still lies in the same place today. On the other hand, the Colorado River has changed color from the preGlen Canyon Dam days of the astronaut training to today.

Spiders Helped Discover Pluto Spiders hold a place among the world’s top five fears. However spiders have become a hotbed for research. Scientists are studying the usefulness of their silk and the potential medicinal properties of their venom. Spiders also have helped astronomers get precise measurements of astronomical bodies for more thana century! To understand the role of spiders in astronomy, we must first be introduced to the filar micrometer. Micrometers are used to measure very small and precise distances. The word “filar” has its Latin roots to the words thread or filament. Filar micrometers use two threads that can be adjusted to measure the angular distance of two objects viewed with a telescope. Using trigonometry, astronomers can measure the distance between objects in space with

By Todd Gonzales

a filar micrometer. However, for a long time, fine translucent filaments were hard to come by and extremely expensive. It became increasingly popular for astronomers to keep spiders and use their silk as the needed filament. At the time Pluto was discovered in Flagstaff, it is likely the reticle used to aim the Pluto Telescope used spider silk. So, even though it was a detail not important enough to log in the observation log, it is extremely likely that spiders share in the discovery of Pluto, by a thread. The reticle used to aim the Pluto Telescope. Currently, it is seen here with fine steel thread used in the 1980’s. Spider silk was more than likely used throughout most of the telescopes operation.
