The Aerospace Corporation will be hosting an information session from 11:00 am – 12:00 pm in ARMS B071 on Thursday, February 24^th.  They are primarily looking for BS/MS/PhD students graduating in May, August, or December 2022.  If you are interested, follow the registration link and upload your resume.  Representatives will review resumes and contact those they would like to interview the afternoon of the 24^th.  Please see the attached flyer for details.

A research seminar will be from 3:00 – 4:00 pm in ARMS 2008 or via Webex.  Drs. Chris Ranieri and George Pollock will be presenting a seminar titled “Al Yah 3 Recovery”.  Additional information is included in the attached flyer.   

More Information About the Information Session and Seminar

Al Yah 3 Recovery

After an Ariane 5 ECA launch anomaly, the Al Yah 3 spacecraft required significantly more fuel to reach its desired GEO mission orbit slot.

Northrop Grumman Innovation Systems and The Aerospace Corporation partnered to design an orbit transfer recovery sequence that maximized the achievable mission life. Using specialized trajectory optimization tools, a recovery sequence was found that maximized the performance of three different propulsion systems. The use of a tool to optimize

the end-to-end transfer was critical and will be highlighted with comparisons to recovery options designed using experience and intuition. A mission life of >8 years was salvaged.

Dr. Chris Ranieri is the Associate Director of the Trajectory Design and Optimization Department and head of The Aerospace

Dr. Ranieri supports these organizations from the Colorado Springs corporate location and helps manage a team located in El Segundo, CA, Colorado Springs, CO, and Albuquerque, NM. Dr. Ranieri brings expertise and insight to the trajectory optimization of maneuvering spacecraft, launch vehicles, and reentry vehicles. This work covers conceptual design and continues through on-orbit operations, at a wide range of analysis fidelity. Dr. Ranieri has spent his entire 15 year career at Aerospace in this department. He has served as a member of the AIAA Astrodynamics Technical Committee and presented to the Under Secretary of Defense (Research and Engineering), the Defense Science Board, and USSF/SSC, SSDP, and DARPA senior leadership. He has also authored or coauthored more than 10 conference and journal papers while at Aerospace. Dr. Ranieri received his B.S. in Aerospace Engineering from Pennsylvania State University and a M.S. and Ph.D. in Aerospace Engineering from The University of Texas at Austin.

Dr. George E. Pollock IV is the director of the Astrodynamics Department at The Aerospace Corporation

Dr. Pollock holds a bachelor’s degree in aeronautical and astronautical engineering, a master’s degree in aeronautics and astronautics, and a doctoral degree in aeronautical and astronautical engineering, all from Purdue University. In over a decade of professional engineering practice, Dr. Pollock has directly contributed to national security space through innovative mission design, system concept analysis, and architecture studies. At Aerospace, he leads a team of analysts providing space domain awareness and advanced space mission analyses for the U.S. Space Force, NASA, and other customers.
