NASA Earth Science UAS Mission Requirements
Don Sullivan
NASA Ames Research Center
Suborbital Science Program
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.
Add to the understanding and prediction of the Earth system. Suborbital observations fill time and space gap between surface observing networks and orbital platforms.

Earth Science Mission Types
• Atmospheric Composition and Chemistry
• Carbon Cycle and Ecosystems
• Climate Change• Water and Energy• Weather• Earth Surface and Interior
UAS System Capabilities
• High altitude, low altitude, stacked• Long range, long endurance• Varied payloads: remote sensing and in situ sampling• Global missions: poles, equator, remote• Over-the-horizon communications• Collaborative planning, scheduling and tracking,especially for
multiple aircraft operationsBeyond Line of Sight

What we did this weekend
When we should have been working on this presentation
Bandwidth and Spectrum Summary
• HALE == Commercial Ku/Ka• MALE == License, arer wide• LAME == Commercial Iridium or equiv• Mixed need all…• NOBODY needs more Ch4 “notes”
