Successful launch of student-built satellite a momentous milestone for students and alumni
A small, student-built satellite, representing six years of collaboration between the Department of Aerospace Engineering Sciences (AES) and the Colorado Space Grant Consortium, launched successfully on Sept. 29 aboard a SpaceX Falcon 9 rocket from Vandenberg Air Force Base. About the size of a small beach ball, the satellite, known as the Drag and Atmospheric Neutral Density Explorer (DANDE), will investigate the varying density of the Earth's thermosphere at altitudes from about 200 to 300 miles above Earth. First contact with DANDE was established the day after launch, and data has continued to stream with all systems performing flawlessly. Since 2007, more than 150 CU students have worked on the project under principal investigator Chris Koehler of Space Grant and AES professors Scott Palo and Jeff Forbes.
Seven CU AES students make "Twenty 20s" list of engineering leaders

Penton's Aviation Week, in partnership with Raytheon, created the new "Tomorrow's Engineering Leaders: The Twenty20s" awards program to recognize top engineering, math, science and technology students. More than a third of the 20 students chosen from institutions across the nation for the 2013 award are CU-Boulder AES undergraduate and graduate students.

Former astronaut and AES senior instructor Joe Tanner accompanied the students to Phoenix, where they were honored during Aviation Week's Aerospace and Defense Programs Conference on Nov. 14. The winning students, pictured above (left to right), are: Kirstyn Johnson, Brad Cheetham, Dan Lubey, Mike Lotto, Jake Gamsky, Paul Anderson, and Erin Griggs.

Student Spotlight: Erin Griggs
A PhD candidate in the CU-Boulder AES graduate program, Erin Griggs is engaged in research to build the next generation of GPS receivers. Working with Professor Dennis Akos, Griggs aims to reduce the size and power needs and improve signal processing of GPS receivers. She is one of the seven CU winners of Aviation Week's "Twenty20s" Awards, and was also recently honored by the Achievement Rewards for College Scientists Foundation.

"CU-AES has provided me with the tools and knowledge to tackle any sort of problem for any phase of an aerospace project, whether it involves high-level conceptual design, hardware implementation, or data analysis from existing missions," says Erin. "The faculty and students are very passionate about space research and technology, which makes it a very fun and exciting place to get your education."

Griggs, who received her undergraduate degree in mathematical and computer sciences from the Colorado School of Mines, enjoys keeping her body as active as her mind. She was a gymnast growing up, and currently volunteers teaching children's gymnastics classes several times a week at a Denver YMCA. She also manages and plays on a non-profit women's ice hockey team that competes all over the state.
AES Alumni Profile: David Goldstein
Colonel David Goldstein (PhD AeroEngr '00, CCAR) is truly an exceptional CU-Boulder aerospace alumnus. Currently the director of the Air Force Research Laboratory's Space Vehicles Directorate and commander of the Phillips Research Site, he is responsible for an annual budget of $300 million and leads more than 800 individuals involved in critical USAF missions including the Air Force space mission communications, position navigation and timing, missile warning, space situational awareness, and defensive counter space. In his current position, he is developing technology to improve the performance and affordability of the next generation of spacecraft bus and payloads.

His PhD advisor, George Born, proudly notes that throughout his career of leadership positions in the Air Force, Goldstein has had a profound impact on the capabilities of our country. Particularly noteworthy are his contributions as GPS Chief Engineer, where he was responsible for improvements to GPS capabilities through redistributing satellites within the constellation to enhance coverage, reallocating signal power onboard newer satellites to provide more robust military capabilities in the presence of jamming, analyzing the compatibility of the European Galileo system with GPS, and in identifying the root cause of an anomaly with SVN49 - openly explaining the anomaly and gathering input from the international GPS user community as he sought to determine the best course of action for future operation.

Deputy Assistant Secretary of Defense for Space Policy Douglas L. Loverro says of Goldstein, "Leaders across the DoD relied on Dave's technical judgment, from Gen. Kevin Chilton, the Commander of US Strategic Command, to Dr. Brad Parkinson, father of GPS, who said he was among the best chief engineers the GPS program had ever had." He has the ability to recognize and resolve thorny technical issues, both making individual contributions to the solution and bringing together teams of military personnel, contracts, and leading experts in the field.

Despite these significant accomplishments and responsibilities, Goldstein remains a down-to-earth engineer, quick to give much credit for his success to mentors like George Born and to the excellent education he received as a graduate student here at CU.
Alumni Class Notes
Jeremy Stober (AeroEngr '92) is the missions operations manager for Kepler, a NASA mission launched in 2009 to find Earth-like planets. Stober, who works for Ball Aerospace & Technologies in Boulder, was the featured lecturer at the Estes Valley Astronomical Society's October meeting.

David Riley (AeroEngr '97) and Julie Bartsch Riley (AppMath '97), along with daughter Avery, are happy to announce the arrival of Cooper Jackson Riley in June 2013. The family lives in Arlington, Va.

Matt Vellone (AeroEngr '02, MS '05) is a project engineer at Wi, Inc. Medical Device Equipment. He joined the CU Engineering Graduates of the Last Decade (GOLD) Board this fall, along with Erin Watson (AeroEngr '06), who works as a spacecraft systems engineer at Ball Aerospace Technologies Corporation.

Shivali Bidaiah (AeroEngr '09) - a systems engineer on the Space Based Infrared System Program at Northrop Grumman Electron Systems - also joined the GOLD Board this fall. She has worked in multiple roles in flight operations, providing engineering support in the Command Products, Operations and Support, and System Test groups. She is currently a technical lead for SBIRS System Test. Bidaiah is pursuing her master's degree in systems engineering at Johns Hopkins University and recently ran her first marathon.

Note from the Chair, Penny Axelrad
This has
been a very
exciting fall
continues to
with 462 undergraduates and 223 grad students. Sophomore classes are bursting at the seams, so we've split into three lab sections. Senior projects is now running 10 projects, ranging from climbing rovers to engine design, autonomous UAVs, and a helio-gyro sail. Graduate projects have expanded to seven, with 67 students from aerospace, electrical engineering, and computer science. We are now also offering 15 of our regular graduate courses via CU's CAETE distance learning program, which allows working professionals to take individual courses in areas of interest or to complete an MS degree entirely online.

We also welcomed three tenure-track faculty. John Evans is an assistant professor specializing in computational fluid dynamics. He comes to us from the University of Texas, where he worked on high-order and structure-preserving methods for computational fluid dynamics, as well as fluid-structure interaction. John is teaching the introductory graduate fluids course. Jim Nabity is an associate professor in bioastronautics. He joins us after 14 years in industry, where he developed life support system components including spacecraft thermal control, emergency oxygen generation, and waste management. A hands-on person, Jim shares his expertise teaching both senior and graduate projects. Jeff Parker is an assistant professor in astrodynamics, returning to CU after working at the NASA Jet Propulsion Laboratory. This fall he teaches intro graduate astrodynamics, and will teach the spacecraft portion of Aerospace Vehicle Design and Performance in the spring.

Just to make sure everyone gets a break once in a while, AES hosted a movie night – inviting students, faculty, and staff to the blockbuster "Gravity." There was plenty of suspension of disbelief, followed by analysis of errors in depicting orbital mechanics, momentum transfer, and the merits of selecting a medical doctor for circuit board replacement, as well an extensive debrief with our resident Hubble repair specialist, faculty member and former astronaut Joe Tanner.

As always, I'd love to get your feedback on what we are doing and updates on your own activities - please email or stop by. Let us know how you'd like to get involved!
