Section News Hello? Is This Outer Space?
On 9 June, students at Leeds Elementary School in Elkton, MD, made the ultimate long distance phone call to a human-occupied outpost orbiting 250 miles above Earth. Audience members sat spellbound as astronaut Col. Jack “2Fish” Fischer on the International Space Station (ISS) squeezed three brown coffee balls out of a straw and caught them deftly in his mouth as he was watched by members of the AIAA Delaware Section, Orbital ATK, and the students and staff at Leeds Elementary. This In-Flight Education Downlink allowed students and educators to interact with an astronaut aboard the ISS during a live question-and-answer session. Downlinks provide the opportunity to learn first-hand from space explorers what it is like to live and work in space. NASA Johnson Space Center’s (JSC) Office of Education facilitates these events, which are designed to enhance student learning, performance, and interest in STEM. The downlink at Leeds Elementary was made possible through partnership between the AIAA Delaware Section, Orbital ATK Missile Defense & Controls Division, and Cecil County Public Schools (CCPS).
Planning for the event began back in January 2016 when the AIAA Delaware Section applied for a downlink during Expedition 49/50. A committee evaluated their application and selected them, but due to mission constraints, NASA could not accommodate the section’s event on their schedule. The Delaware Section began the process again in fall 2016 for Expedition 51/52 . . . and . . . success! The section and school were notified in January 2017 that the ISS was scheduled to conduct a downlink with the school in late spring 2017.
Immediately, the Delaware Section, Orbital ATK, and Leeds Elementary School began to prepare for the event. Orbital ATK contributed by sponsoring a Franklin Institute (Philadelphia, PA) traveling science show assembly at the school that presented the subject of “Life in Space” where the students embarked on a trip to space and explored the scientific and engineering challenges of getting to space, living and working in orbit, and safely returning to Earth. The AIAA Delaware Section participated with classroom presentations on human space exploration and guiding the students through astronaut training and launching sodium bicarbonate rockets. In the weeks leading up to the downlink, students followed 2Fish on social media and watched his spacewalks via NASA TV. Art classes were used for students to design their own planets, and teachers integrated discussions about space station life into their curriculum. “There’s a lot of planning that goes into this event,” said Tim Dominick, Public Policy Chair with the Delaware Section and lead organizer of the event. “We wanted to help prepare the students, get them excited, and give them as much background as possible to interact well with the astronaut.”
On the day of the event, many local, state, and federal elected officials attended. The event began with the Leeds Elementary band playing the theme from Star Wars and the school chorus entertained everyone by singing “I.S.S. (Is Somebody Singing)” written by retired Canadian astronaut Chris Hadfield and Ed Robertson (Bare Naked Ladies). Leeds Elementary Principal Nikole MacDowell made the opening radio call with Jack Fischer, and Cecil County Executive Dr. Alan McCarthy welcomed Col. Fischer to Cecil County. Then 20 students, preselected by their teachers, each asked 2Fish a question ranging from “What is your favorite thing to eat in space?” (coffee balls!) to “What tools are you using to study the effects of microgravity on bones?”. The questions were generated by each classroom and had been sent to NASA JSC’s Office of Education ahead of time to ensure that the astronaut was prepared and in case audio difficulties prevented him from hearing the students’ questions. Throughout the downlink, the 400 kids sat quietly while listening to his answers and watching him perform “Astronaut Tricks” on the large screen. The downlink wrapped up with Vice Principal Allyson Veasey thanking 2Fish for sharing this experience with the students.
Leeds Elementary School is the second school in Maryland to host a downlink with astronauts on the ISS, and it was the sixth downlink ever to occur in Maryland. Four of the previous downlinks were hosted by either NASA Goddard Space Flight Center or the Maryland Science Center. The number of in-flight education downlinks varies each year based on mission operations, but on an average year, NASA conducts around 12 to 14 with educational organizations across the country. Downlinks have been performed continually on the ISS since Expedition 1.
Two days after the downlink, the ISS made a pass over Elkton. The AIAA Delaware Section made posts on social media with viewing information to alert students and families to go outside to watch the ISS pass and wave “hi” to 2Fish. It was inspiring to see the connection the students made between just having had the downlink and now seeing the ISS pass overhead.

AIAA Program AIAA Leadership Takes Part in NASA Langley Centennial Symposium
By Hannah Thoreson
From 12 to 14 July, a symposium was held at Hampton Roads Convention Center as part of the celebration of NASA Langley Research Center’s 100 years of technical excellence. Tom Irvine, managing director of Content Development at AIAA, moderated a panel titled, “Aeronautics Research Partnerships: Celebrating the First 100 Years and Looking Forward to the Future.” Irvine said, “The contributions and the research and the work done at Langley, either as government research or as cooperation and collaboration with U.S. industry, has truly been a success story that makes aviation what it is today.” Robert D. Gregg III, Tom L. Wood, Dr. Robert H. Liebeck, and Dr. Mark Lewis also discussed advancements in aeronautics.
AIAA Executive Director Dr. Sandra Magnus also moderated a panel at the symposium: “Future of Aerospace in the Next 20–30 Years.” She explained that projecting out maybe 100 years is a purely creative problem, but that a more narrow focus, like 20 or 30 years out, has constraints that are a bit easier to understand. Magnus added, “20 or 30 years is long enough and far enough into the future that there are still going to be some curveballs that come at us from outside the community as well as breakthroughs that come out within the community.” Panelists Gregory Williams, Stephen G. Jurczyk, Dennis Andrucyk, and Robert A. Pearce spoke about the innovations to come in the next decades.

STEM Activities AIAA Tucson Section Helps Scouts Fly High at Raytheon Scouts Day
The K–12 STEM Outreach Committee would like to recognize outstanding STEM events in each section. Each month we will highlight an outstanding K–12 STEM activity; if your section would like to be featured, please contact Elishka Jepson (firstname.lastname@example.org).
On 2 February, Raytheon Missile Systems held its 8th annual Scouts Day, an event where engineers volunteer their time to assist nearly 300 scouts in their quest to acquire a STEM-related merit badge. Volunteers developed lessons and activities that cover all of the requirements for specific merit badges. This year, 13 different badges were offered, ranging from robotics to space exploration. The AIAA Tucson Section was pleased to offer the Aviation merit badge as a part of this program.
In 2011, several Tucson section members volunteered at the second Raytheon Scouts Day. They were so impressed by the event, and the positive impact on the scouts, that they decided to develop their own merit badge curriculum. They decided on the Aviation merit badge, a logical fit for AIAA. The Tucson Section held its own Aviation merit badge day later in 2011. With a developed curriculum in hand, and some experience under their belt, the section approached the Raytheon Scouts Day organizers about adding the Aviation merit badge to their event. AIAA was welcomed enthusiastically, and has participated in every Raytheon Scouts Day since 2012.
During the day, Aviation merit badge participants gain a variety of aerospace knowledge. They start with a lesson on how an aircraft flies, then move on to the fundamental aircraft flight instruments and how to read them. Scouts then rotate through a series of activities, including foam glider construction, and taking the controls of a Cessna 172 flight simulator. The section also provides career speakers for the scouts. One of the long-time aviation merit badge volunteers, Tom Mouch, is an engineer and former Air Force Academy instructor; the scouts always learn a lot from his experience and career path.
If you are interested in hosting an Aviation merit badge day in your section, please contact Elishka Jepson at email@example.com. The Tucson Section would be more than happy to share their slides, handouts, and activities, and offer any assistance in helping you start your own program.

Juno’s Magnetometer is MAG-nificent
By Taylor Honeycutt
How It Works:
Juno spacecraft’s magnetometer, also known as MAG, is an instrument that measures the magnetic field of Jupiter. It consists of two components: the Fluxgate Magnetometer (FGM) and the Advanced Stellar Compass (ASC). The FGM measures the strength and direction of Jupiter’s magnetic field, and the ASC measures the orientation of the spacecraft. Both sets of the MAG instruments are positioned away from the rest of the spacecraft on a boom to isolate it from the spacecraft’s magnetic effects caused by Juno’s other instruments. Juno circles Jupiter in a polar orbit which allows MAG to measure the strongest and weakest magnetic fields. This orbit also provides Juno access a larger fraction of the surface than are permitted by other orbits.
Why It Helps:
Jupiter’s surface is divided into bands, which includes the famous Great Red Spot and other, smaller storms. A limited number of previous missions to Jupiter measured its magnetic fields. Few probes have penetrated the surface of Jupiter; the ones that have were frozen and crushed by the planet’s pressure, and thus did not live to tell the tale. Because no probe has been able to measure the inside of a gas giant planet, we don’t understand the insides of gas giant planets’ well. Studying Jupiter’s magnetic field via MAG will allow us to learn more about this topic and help us better understand other gas giant planets.
The Sun goes through an 11-year cycle, and Jupiter’s magnetic fields are strongly affected by the Solar wind. This Solar wind has a big impact on the overall “space weather”. The measurements which Juno makes likely measure the planet in conditions never measured before.
The orbit of Jupiter’s innermost seven moons (including Io, Europa, Ganymede, and Callisto) are all within the magnetosphere. The upcoming mission to Jupiter’s icy moon, Europa, is currently being designed, and the launch is being planned for 2022. It would be immensely helpful to have a better grasp on the magnetosphere of Jupiter so we can ensure the spacecraft is designed to survive the mission. An example of this is the fact that sometimes Jupiter releases bursts of its trapped particles in the form of cosmic rays, the most energetic particles in nature. The speed of these particles is close to the speed of light. Having some of these cosmic rays released when the Europa mission spacecraft is near could be disastrous. It would be good to understand these effects in order to better design the Europa spacecraft.
The Juno mission may help improve models of star formation for the smallest stars that are only a few times more massive than Jupiter itself. This may help us answer questions raised by the discovery of solar systems like Trappist-1, a collection of planets surrounding a very small star similar to Jupiter that was discovered recently. While the Sun is one thousand times larger than Jupiter, the Trappist-1 star is only 80 times more massive than Jupiter. The magnetic field of the Trappist-1 star may be much closer to Jupiter’s than it is to the Sun’s, so the Juno mission might be able to help us better understand other solar systems. Perhaps Juno will be able to help us answer some of mankind’s oldest questions.

Juno Instrument: The “JEDI” on Flight
By Nikhil Keer
Anyone interested in Roman mythology, is probably familiar with the myth related to the king of gods, Jupiter and his wife, Juno, the goddess of marriage. It is believed that to conceal his affairs, Jupiter hid himself behind a veil of clouds, but Juno peeked through the clouds and unveiled his true nature. With about 67 moons orbiting it, the largest planet Jupiter bears resemblance to the Roman god, and spacecraft Juno that entered Jupiter’s orbit on July 4, 2016, has reached beneath its clouds to unlock its secrets. Certainly no misbehavior is expected there, but the mission will definitely shed light on Jupiter’s origin and evolution and in turn enhance our understanding of the history of the solar system.
Built by Lockheed Martin and operated by NASA’s Jet Propulsion Laboratory, spinning spacecraft Juno was launched on August 5, 2011 aboard an Atlas V551 rocket from Cape Canaveral, Florida. With this ninth mission, Juno is closer to the gas giant than any other spacecraft in the past. Powered by the sun, this environmentally friendly spacecraft is the first to make the farthest solar-powered trip in the history of space expeditions. Juno, unlike the previous Galileo spacecraft that faced major radiation problems as it orbited around Jupiter’s equator and had to be terminated, Juno will orbit elliptically over Jupiter’s poles at least 37 times, avoiding its densest radiation belts while observing and collecting information about its gravity and magnetic fields, atmospheric dynamics and composition, and evolution.
Although Juno is unmanned, there are some special guests hitchhiking a ride aboard the spacecraft, the three mini aluminum Lego toy figurines, that of the Roman god Jupiter, his wife Juno, and Galileo, who made several important discoveries about Jupiter. But along with these celebrities, gracing the spacecraft with its powerful presence is a shoe-box size JEDI, The Jupiter Energetic Particle Detector Instrument. The JEDI is one of the nine scientific instruments that Juno is carrying to study the planet, namely, Gravity Science Experiment, Magnetometer (MAG), Microwave Radiometer (MWR), Jovian Auroral Distributions Experiment (JADE), Waves, Ultraviolet Imaging Spectrograph (UVS), Jovian Infrared Auroral Mapper (JIRAM), and JunoCam, each performing an important task. The Gravity Science Experiment and Magnetometers study Jupiter’s deep structure by mapping the planet’s gravity field and magnetic field. The Microwave Radiometer probes Jupiter’s deep atmosphere and measures how much water is there. The JEDI, JADE and Waves test electric fields, plasma waves and particles around Jupiter to determine how the magnetic field is connected to the atmosphere, and especially the auroras. The UVS and JIRAM use ultraviolet and infrared cameras to take images of the atmosphere and auroras, including chemical fingerprints of the gases present and JunoCam takes spectacular, first ever, close-up, color images of Jupiter.
The Jupiter Energetic Particle Detector Instrument was developed by the investigation team led by Barry Mauk at the Johns Hopkins Applied Physics Laboratory (APL). Its measurement techniques are based on technologies used by the previous Galileo mission and New Horizons Pluto Energetic Particle Spectrometer Science Investigation (PEPSSI). In January 2016, even before Juno reached Jupiter, the JEDI was turned on to perform science operations to investigate the space that lead up to Jupiter. The JEDI is located on the spacecraft’s upper deck and consists of three identical, fast processing shoebox-sized detectors with six ion and six electron views. These detectors are placed every 120 degrees producing a continuous 360-degree view of the space around Juno. Being the largest planet, Jupiter has an enormous magnetic field (second most intense in the solar system) which traps clouds of charged particles (electrons and ions) within its space environment called the magnetosphere. These high speed energetic particles (the electrons, proton (hydrogen) ions, helium ions, sulfur ions, oxygen ions, and neutral atoms) come under the influence of the magnetic field, and get drawn towards Jupiter’s poles. The detectors use microchannel plates and foil layers to detect the energy, angle and types of ion within a certain range. They measure electrons in the energy range of 25 kilo electron Volt (keV) to 800 keV and ions in the energy range of 10 keV to 8000 keV. The JEDI measures the high energy component of the ions and electrons in conjunction with the JADE instrument that measures the lower energy components (below 30 keV). The JEDI detectors measure these particles by the amount of energy they carry, their type and the direction in which they are moving around Jupiter. An important feature of these detectors is that they can measure particles coming from many different directions, all at the same time. They also study these particles’ interactions with Jupiter’s atmosphere, which create its brilliant and enormous polar auroras (the bright northern and southern lights), the most powerful ones in the entire solar system. This data captured by the JEDI will help scientists answer questions like where the particles come from, how they are energized, and what triggers the release of energy from these particles into brilliant auroras. The JEDI works in conjunction with the other instruments, JADE and Waves, and collectively they contribute to Juno’s overall mission to learn more about Jupiter’s origin, structure, atmosphere and magnetic field.
Just like all good things must come to an end, after over more than a year in orbit, sometime in 2018, Juno’s mission will be complete and it’ll dive into Jupiter’s atmosphere, disintegrate and burn up like a meteor. But until it deorbits and sacrifices itself, just as the peacekeeping Jedi from Star Wars studied, served, and used the mystical energies of the Force, Juno can rely on the scientific powers of its JEDI that feels the Force of the particles and will ensure successful mission completion. As the end draws closer, NASA scientists eagerly await new discoveries, the rich “Returns from the JEDI” and wish it good luck while bidding goodbye, as a Star Wars Jedi might say….. “May the Force be with you”.
Technical Committees Society and Aerospace Technology Integration and Outreach Committee (SAT IOC)
By Dr. Amir S. Gohardani, SAT IOC, Chair
The Society and Aerospace Technology Integration and Outreach Committee (SAT IOC) marks the new name for the former Society and Aerospace Technology Technical Committee under a new AIAA governance structure. SAT IOC combines different activities linked to AIAA’s mission to inspire and advance the future of aerospace for the benefit of humanity. One of the strengths of this IOC is the diverse interest of its membership ranging between Astrosociology to more traditional perspectives of measuring the societal impact of aerospace activities.
Recent committee endeavors included collaboration with the AIAA Tucson Section for a joint booth at the Phoenix Comic Con. This event was attended by over 100,000 people and exemplifies a new way to enable the members of the general public in gaining unprecedented insight into AIAA activities. During the AIAA forums, SAT IOC generally supports the Space History, Society, and Policy Track examining the history of our time in space, space law and policy, international cooperation, the societal impacts of aerospace technologies and an educated and trained workforce, and the evolution of our spacefaring society.
At a recent event, R. Steve Justice, SAT IOC Past Chair (2015–2017), was recognized for his committee leadership and commitment. “I would like to thank Mr. Justice for his exceptional committee leadership and for his many contributions that have assisted in shaping a diverse and active committee. We will continue pursuing key committee objectives with the same enthusiasm as before,” the new SAT IOC Chair, Dr. Amir S. Gohardani stated. SAT IOC looks forward to collaborating with other AIAA committees.
