1st IAA Conference on Space Situational Awareness

Nov. 13-15, 2017

Orlando, FL

Keynote Presenters

Moriba K. Jah 
Associate Professor, University of Texas Austin
Aerospace Engineer and Astrodynamicist

Moriba Jah, Associate Professor at the University of Texas Austin, brings to bear his experience -- navigating for NASA Mars missions and working for the Air Force in situational awareness -- as he steers UT Austin to being a world center of research and discovery on how objects behave in outer space.

Jah has led research programs in space object behavior assessment and prediction for the Air Force Research Laboratory since 2007. He directed the Air Force’s Advanced Sciences and Technology Research Institute for Astronautics, or ASTRIA, on Maui, Hawaii, for eight years, and for the last two years has headed the space situational awareness program at Kirtland Air Force Base in Albuquerque, New Mexico.

As a spacecraft navigator (a title he shares with few people) for the NASA/Jet Propulsion Laboratory from 1999 to 2006, Jah charted courses for the Mars Global Surveyor, Mars Odyssey, Mars Exploration Rovers and Mars Reconnaissance Orbiter. He also has participated in missions to the red planet for the European Space Agency, or ESA, and to asteroid Itokawa with the Japanese space agency, JAXA.

Jah, UT Associate Professor of Aerospace Engineering and Engineering Mechanics, received his bachelor’s degree in aerospace engineering from Embry-Riddle Aeronautical University in Prescott, Arizona, in 1999 and his master’s and doctoral degrees in aerospace engineering sciences from the University of Colorado, Boulder, in 2001 and 2005.

He is a fellow in the American Astronautical Society, the Air Force Research Laboratory and the Royal Astronomical Society, an associate fellow in the American Institute of Aeronautics and Astronautics. He is now an Associate Editor for the Journal on Advances in Space Research, official journal of the Committee On Space Research (COSPAR) in the areas of Astrodynamics and Space Debris. He has authored or co-authored more than 75 articles in astrodynamics, engineering and other professional peer-reviewed journals and is a popular speaker on the topic of spacecraft debris, which he calls "the unknown iceberg equivalent in space."

From 2005-2009, Dr. Horack had an impressive career at NASA’s Marshall Space Flight Center (MSFC) having achieved the level of Senior Executive Service. His last position at NASA was as manager of the Science and Mission Systems Office, where he was responsible for advanced, complex science and exploration research and nearly 400 civil service personnel and contractors. He held several titles while at MSFC, including assistant manager of the Science and Mission Systems Office, assistant director of the Space Transportation Programs and Projects Office, assistant director for science communications in the Space Sciences Laboratory, and assistant mission scientist for the Astro-2 payload that flew on the Space Shuttle Endeavour.

Dr. Horack earned a B.A. in Physics and Astronomy from Northwestern University, and an M.A. and Ph.D. in Physics from UA-Huntsville in 1992 and 1993, respectively. He has authored or co-authored more than 100 papers and conference presentations.  He has spoken at numerous universities, research institutes, and industrial organizations. He is also a member of the American Association for the Advancement of Science, the American Astronomical Society, the American Institute for Aeronautics and Astronautics, and serves as Co-Chair of the International Astronautical Federation’s Space Transportation Congress. In addition, Dr. Horack is an FAA licensed private pilot with instrument and commercial pilot ratings, and an FAA flight instructor.


Dr. George C. Nield
Associate Administrator for Commercial Space Transportation, FAA

Dr. George C. Nield serves as the Associate Administrator for Commercial Space Transportation at the FAA. He has over 30 years of aerospace experience with the Air Force, at NASA, and in private industry.  Dr. Nield came to the FAA from the Orbital Sciences Corporation, where he served as Senior Scientist for the Advanced Programs Group. His previous assignments include working as an Astronautical Engineer at the Space and Missile Systems Organization, a Flight Test Engineer at the Air Force Flight Test Center, and an Assistant Professor and Research Director at the USAF Academy.  He was the Manager of the Flight Integration Office for the Space Shuttle Program at the NASA Johnson Space Center, and later worked on both the Shuttle/Mir Program and the International Space Station Program. He is currently a member of the Aerospace Safety Advisory Panel, which provides support and advice to the NASA Administrator.  A graduate of the United States Air Force Academy, he holds an M.S. and Ph.D. in Aeronautics and Astronautics from Stanford University, and an MBA from George Washington University.  He is also a Flight Test Engineering graduate of the USAF Test Pilot School.  Dr. Nield is a registered Professional Engineer and a Fellow of the American Institute of Aeronautics and Astronautics.


 Dr. Hogler Krag

Dr. Holger Krag has been a Space Debris Analyst in the Space Debris Office of ESA/ESOC located in Darmstadt, Germany, since 2006. He has worked on the operational conjunction event analysis for various ESA missions, debris risk assessment, mitigation analysis and the Surveillance and Tracking Segment of the European SSA system. Since 2014, he is head of the Space Debris Office. He represents ESA in the IADC (Inter Agency Debris Coordination Committee) and is co-leading the SST segment of ESA’s SSA program. He has also become ESA’s lead engineer for the implementation of the telescope network for the Spanish Surveillance System that will form part of the EU SST system.
