  3. Layered Sensing System Approach Ranging, Orbit & Spin Determination Surface & Structural Characterization Proximity Operation & Capture Long-Range Imaging Ground Penetrating RADAR LADAR Cubesat Flybys CubesatImpactors 1,000km 100km 10km 1km 100m 10m Strawman Mission: Orbit Condition 1, H mag 28.5, diameter, mass, spin rate and binary status unknown Our suite of overlapping sensors characterizes the target asteroid during approach while minimizing risk to the main craft

  4. 10,000 to 1,000 km: Long-Range Imaging • Critical to discover the Asteroid early in the approach • Early maneuvers preserve fuel • Extends available time for staged approach to the asteroid • Visible and Near IR best bands for detection at long-range • Comparison of visible and IR data leads to preliminary size and mass information • High resolution imaging leads to preliminary spin state determination • Multi wavelength and hyper-spectral data yield clues on volatiles and surface composition Image credit: NASA/JPL-Caltech Early detection and characterization of target asteroid reduces mission risk

  5. 100 to 10 km: Ground Penetrating Radar MRO SHARAD Antenna Image credit: NASA Mars Express MARSIS Antenna Image credit: NASA / ESA / JPL-Caltech / U. of Rome / Washington U. in St. Louis Image credit: ESA We offer extensive experience in developing space borne radar systems

  6. 50 km: LADAR LADAR Data • High resolution 3D surface model with surface resolution to 10 cm • Spin state determination to 1 % • NGAS LADAR System • Single-photon sensitive focal plane array • Highly efficient fiber laser • Tested in air applications Pulsed fiber laser Photon counting IPD Our ground tested LADAR system enables highly resolved 3D topographic models

  7. 10 to 1km: Cubesat Flyby Image credit: NASA/JPL-Caltech/Montana State University Radar: Range 4km • NG’s Plymouth Cubesat supports Camera/RADAR & LIDAR instruments and can be launched from a safe distance for the main craft (1-10 km) towards the target • The 3-Axis stabilized CubeSat platform allows maneuvering around asteroid for 4 weeks • Gravitational field can be determined by monitoring main craft to CubeSat separation 40° 6° 10° Ladar: Range 1km Camera: 4 megapixels Our CubeSat bus offers close quarters characterization without risk to the main craft

  8. 100 m: CubeSatImpactor • Ames Research Center and Northrop Grumman have developed low speed impactors based on CubeSat technology • Multiple spherical thumper impacts at 1-5m/s provide detailed acceleration information & internal structure • 1U impactors use multiple cameras to provide before & after impact close up images Image credit: HONEYBEE Robotics Multiple thumpers can test the surface properties of the asteroid while the primary vehicle remains at a safe distance

  9. Summary • Northrop Grumman offers a complete suite of proven sensor systems to support Asteroid Characterization, proximity operation and capture • High performance CubeSats offer the essential capability to probe the target asteroid without risk to the main spacecraft • Cubesat concepts can be space proven in LEO for relatively low cost. • Due to the high TRL level of the elements, our integrated sensor system is ready to support a 2017 launch date
