KaBOOM’s Primary Goals
Build a high power, high resolution
radar system for:
• Precision tracking and
characterization of near Earth
objects to…
– Save the Earth from asteroid
impacts.
– Select asteroids for human
exploration.
• Tracking orbital debris…
– Down to 5cm at GEO.
– Protect astronauts on the ISS and
satellites up to GEO.

Ka-Band First Step: KaBOOM
Demonstrate coherent uplink arraying with real time atmospheric phase fluctuation compensation at Ka band, operationally
demonstrating a low life cycle cost, self calibrating, stand alone system.
21
• Real time atmospheric twinkling compensation at Ka-band.
• A phased array of widely separated (60m) antennas
• Leading to a high power, high resolution radar system
At NASA Kennedy Space Center
KaBOOM builds on previous successfully demonstrated concepts, technologies and
methods to prove the final steps towards an operational coherent array radar capability.

Objectives Completed
UAS flights at Craters of the Moon, Idaho, were the first in the
country approved by the NPS after June 2014 ban went into effect.
Successfully completed 41 UAS flights over lava flows at Kings
Bowl, Inferno Chasm, and near Craters of the Moon visitor center’
Demonstrated the types of data sUAS’s could provide as part of
SSERVI FINESSE proposed work. Data included detailed image
overlays, DEM models, remote terrain inspection, and 3D models.
This is year 1 of a 5 year SSERVI project, utilized as a checkout of
the capabilities and data processing tools.

Moon Summary
NASA Airworthiness / Pilot Certification
• Multi-rotor vehicles approved via NASA and KSC airworthiness
processes.
• KSC pilots and observers trained per NPR 7900.3C (NASA’s Aircraft
Operations Management
Manual) requirements.
• Flew UAS missions under
NASA/FAA COA advisory
system with NOTAM’s issued
out of Salt Lake City (SLC).
