Building model rockets and counting down to launch, 3…2…1…<br/></p><img alt="" src="/news/PublishingImages/Liz%20with%20Dream%20Chaser.JPG?RenditionID=1" style="BORDER:0px solid;" /><div id="__publishingReusableFragmentIdSection"><a href="/ReusableContent/36_.000">a</a></div><p>Liz Antognoli made her dreams real. After earning her bachelor's degree in mechanical engineering at Washington University in St. Louis in 1997, her career lifted off at NASA's Johnson Space Center in Houston. Now, following a dozen years as a flight controller, she is helping develop a new generation of vehicles to deliver people and payloads into orbit.</p><p>Antognoli, 42, is a systems engineer for NASA contractor Sierra Nevada Corp. in Louisville, Colo. The company is building the Dream Chaser, a reusable, autonomous spacecraft capable of being launched into low-Earth orbit atop an Atlas V rocket. One version — Antognoli's — will deliver cargo to and from the International Space Station (ISS). The vehicle resembles a mini space shuttle and is about one quarter of the size of the venerable spacecraft retired by NASA in 2011.</p><p>Dream Chaser is scheduled to make at least six cargo service missions between 2019 and 2024. Antognoli is at the heart of that effort, responsible for the integration of NASA's diverse cargo needs with the design, processes and operations Sierra Nevada engineers are developing to meet them.</p><blockquote>"Since I was six years old I wanted to be part of the space program," she says, "and I still find it challenging and inspiring."</blockquote><p>Growing up outside Chicago in Wheeling, Ill., Antognoli was fascinated with science. Physics class captivated her during high school, and guidance counselors suggested she pursue engineering.</p><p>"My dad took me around the country visiting colleges, and I fell in love with the WashU campus," Antognoli says. "I wanted to have opportunities to be well rounded and found them. I learned a lot about myself while I was there. It was the best place to allow essential elements of my personality blossom and come together."</p><div style="width: 100%; font-size: 0.9em; font-style: italic; color: #555555; padding: 0px 10px 10px 0px;"><div style="text-align: center;"> <img src="/news/PublishingImages/Wash%20U%20Move%20in%20Liz%20Antognoli.jpg?RenditionID=1" alt=""/> </div><div style="text-align: center;">Liz Antognoli, 1993<br/></div></div><p>Upon graduation, Antognoli began her career with NASA contractor United Space Alliance at Johnson Space Center. She served as a mission planner and flight controller while also remotely earning a master of science degree in space operations from the University of Colorado at Colorado Springs. NASA later became her direct employer, but all the while Antognoli was responsible for essential elements of space shuttle missions and ISS assembly. Highlights included the integration of the station's robotic arm and various cargo transportation and retrieval missions.</p><p>"On those missions I spoke directly to (shuttle and ISS) crew members every day to discuss cargo transfers and answer questions," Antognoli says. "That was one of my favorite things I've done in my career."</p><p>Antognoli found her way to Sierra Nevada and Dream Chaser when the space shuttle program wound down. She also began a side venture called Mission Control Education LLC, developing manuals and lesson plans to assist teachers in recreating NASA mission control centers in their classrooms to inspire future engineers.</p><p>Antognoli's study of the physical world has coincided with a complementary exploration of her inner self. Early in her NASA career, she found herself feeling angry and judgmental about herself and others. </p><p>"I had checked a lot of boxes that are supposed to represent success and happiness, but my inner life was not as joyful," she says.<br/></p><blockquote>She began searching within herself, and credits Fr. Gary Braun, director of WashU's Catholic Student Center, with sowing seeds of introspection during her college days.</blockquote><p>"He helped me examine approaches to spirituality and the questioning of beliefs," Antognoli said. </p><p>That process led to an introduction to yoga and the study of eastern philosophy. Her practice became so life-changing that for the past 14 years she has complemented her space operations career by teaching yoga and leading Ayurvedic workshops.</p><p>At home, Antognoli and her wife, Jen, are also busy raising their one-year-old son, Luca, and chasing around their dog, Mowgli.</p><p>Antognoli encourages today's WashU students to try new things, even if that means following a nonlinear path. </p><p>"Trust your interests and the things that provide you with inspiration and passion," Antognoli says. "If something is working, keep going. If it's not, change it."<br/></p> <SPAN ID="__publishingReusableFragment"></SPAN> <p> <br/> </p><span> <div class="cstm-section"><h3>WashU Women & Engineering</h3><div> <strong></strong></div><div style="text-align: center;">Women & Engineering was established as an organization for engineering alumnae from Washington University in St. Louis to support each other; inspire and mentor our women students; and help shape the School of Engineering & Applied Science.</div><div style="text-align: center;"> <br/> </div><div style="text-align: center;"> <span style="font-size: 1em;"> <a href="/alumni/programs-events/Pages/women-engineering.aspx">>> Read more & get involved</a></span></div></div></span> Liz AntognoliChristopher Tritto2017-10-16T05:00:00ZNASA veteran Liz Antognoli, EN '97, is helping develop a new generation of spacecraft to deliver payloads into orbit.<p>​NASA veteran Liz Antognoli is helping develop a new generation of spacecraft to deliver payloads into orbit<br/></p> First 40: Tim Tague recorded a second of video a day<p>Meet Tim Tague — Washington University in St. Louis Class of 2021.<br/></p><p>Back in August, we asked these first-year students to record one second of video every day for their first 40 or so days on campus.

Sometimes I’ll pause, look around and take a video. It’s made me realize how lucky I am to be in this place. So much has happened in these past 40 days. I can only imagine what will happen in the next four years.”</p><h3>Why did you pick Washington University?<br/></h3><p>If you were to ask me my favorite sport, I would answer football in the fall and baseball in the spring. I couldn’t imagine giving either one up, and WashU gave me the opportunity to play both. And, of course, it’s a really good school. That combination of academic and athletic excellence drew me here.<br/></p><h3>What’s dorm life like?<br/></h3><p>I live in a six-person suite. We all play either football or baseball, and one guy plays both like me. We play a lot of “Rocket League,” and we eat together. Whenever someone gets hungry, they shout out “BD” and we all go together. Some of my friends from home talk about all of the free time they have in college, but it seems like I always have work to do or practice to go to. However, I am really enjoying all the time I spend doing this work and the hours spent at practice, so the days go by very quickly. It would be nice to sit on the bed for one day and take a nap, but I guess that’s what break is for.<br/></p><h3>Have you joined any clubs?</h3><p>I’ve joined the Bear Cubs Running Team, which is a running club for kids on the autism spectrum. Annie Marggraff (AB 2017), who started the program, lives one town over from me and started a chapter back home that my sister, Nicole, joined. My sister has a rare genetic condition and faces so many challenges, but when she runs — something a lot of us complain about — she always has the biggest smile on her face. She is so positive and happy. I wanted to meet kids in similar situations and learn from them the way I’ve learned from Nicole.<br/></p><p><br/>​</p> <span> <div class="cstm-section"><h3>Tim Tague<br/></h3><div> <strong></strong></div><div><strong>Hometown:</strong><span style="color: #3c3d3d; font-family: 'source sans pro', 'helvetica neue', helvetica, arial, sans-serif;"> Orinda, Calif.<br/></span><br style="box-sizing: inherit; color: #3c3d3d; font-family: 'source sans pro', 'helvetica neue', helvetica, arial, sans-serif;"/><strong>Major:</strong><span style="color: #3c3d3d; font-family: 'source sans pro', 'helvetica neue', helvetica, arial, sans-serif;"> Mechanical engineering </span></div></div></span>Tim Tague Diane Toroian Keaggy Tim Tague — Washington University in St. Louis Class of 2021. Makerspace will foster innovation and entrepreneurship<p>​“I believe making things with your hands is essential to being a truly well-rounded engineer,” says Washington University Trustee Donald Jubel, BS ’73, chief executive officer of Spartan Light Metal Products. “You can learn the nuances of using different materials. You also learn to have respect for the people who actually make products. I have designed things that have turned out to be almost impossible to make. Learning from your mistakes is a great teacher.”<br/></p><img alt="" src="/news/PublishingImages/Spartan-Light-Metal-Products-Maker-SpaceFINAL-1aj0guj.jpg?RenditionID=1" style="BORDER:0px solid;" /><p>​To give Washington University students enhanced opportunities to learn by working with their hands, Spartan has pledged $1 million to create the Spartan Light Metal Products Maker Space. The cutting-edge facility will be centrally located on the ground floor of <a href="">Henry A. and Elvira H. Jubel Hall</a>, which was named in 2013 with a substantial commitment from the Jubel family through the Henry A. Jubel Foundation. Jubel Hall, part of the university’s east end transformation project, will be completed in 2019 and will house the Department of Mechanical Engineering & Materials Science in the School of Engineering & Applied Science.<br/></p><p>The Spartan Makerspace will transform the way students and faculty members interact with their subject matter in many areas of study. Its state-of-the-art resources will include 3D printers and scanners, plasma cutters, computer-controlled milling machines, and lathes for cutting metal. Such tools can be used to create everything from tech products and biomedical devices to sculptures and architectural mock-ups.</p><blockquote>“The makerspace will accelerate innovation and entrepreneurship across Washington University,” says<a href="/Profiles/Pages/Philip-Bayly.aspx"> Philip Bayly</a>, chair of mechanical engineering and the Lilyan and E. Lisle Hughes Professor. “It will provide a place where innovators can bring to life designs for addressing society’s challenges.</blockquote> <p>“For entrepreneurs, working prototypes are a huge help in demonstrating an idea in order to obtain patent protection, convince investors, and attract customers,” he adds. “The Spartan Makerspace will provide students and faculty with sophisticated fabrication capabilities that will allow them to have an even greater impact on our world.”</p><p>In 1961, Donald Jubel’s father, Henry Jubel, BS ’40, founded Spartan Light Metal Products, which has become an industry leader in the design and manufacture of aluminum and magnesium custom diecasting products and assemblies. He attributed his success to his Washington University education. Beginning with Henry, three generations of the Jubel family have earned degrees in mechanical engineering at the university, including Donald and his daughter Lindsey, BS ’09, MS ’09.</p><p>For decades, the Jubel family has provided extraordinary support and leadership for Washington University. The family and its foundation have directed significant gifts and annual support to scholarships and programs in the engineering school and to the Alvin J. Siteman Cancer Center. Among his many roles, Donald is a member of the engineering school’s national council and the university’s Alumni Board of Governors. His daughter Melissa Markwort, EMBA ’14, is a member of the LEAD Initiative committee for the engineering school and the Family Business Steering Committee for Olin Business School. She also serves as chair of the Fellows Committee for the William Greenleaf Eliot Society.</p><p>“The Jubels have championed both education and manufacturing in our region and beyond,” Professor Bayly says. “It means a great deal to the university for the maker space to bear the Spartan name.”<br/></p><br/><br/><br/> <span> <div class="cstm-section"><h3>Henry A. and Elvira H.
