2 Suborbital Science Programs Objectives Development of new space sensors and new remote-sensing techniques. Satellite calibration/validation. Targeted observations of ephemeral phenomena with variable temporal and spatial scales. Atmosphere/near-space in-situ observations. Improvement and validation of predictive Earth process models using satellite data. Next-generation scientists with hands- on sensor hardware and field experiment experience. To understand and protect our home planet, we need data from multiple perspectives. Suborbital fills time and space gap between surface observing networks and orbital platforms. Sounding Rocket Program Balloon Program Aircraft & UAV Programs

3 Suborbital (Aircraft/UAVs) Program Catalog Demonstrated or proven platforms from a variety of sources, selected based on 3-5 year science requirements. New Technology Platforms Finite (5-10yr) commitments (e.g. long-term leases) of experimental platforms & enabling technologies, to enable new science from new vantage points. Science Missions & New Sensors Integrated mission & field campaign management for all suborbital earth science missions; potential to include sensor development to accompany new platform capabilities.
