Suborbital Science Program Manager
How is the Earth changing and what are the consequences of life on Earth?
A Comprehensive Global Observing System
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
Aircraft & UAV Programs
Higher altitude rockets with high resolution instruments opened the door to a whole new class of auroral physics phenomena.
New PhysicsNew Capabilities on Sounding Rockets Enabled New Studies of Auroral Physics
Discovered the source of auroral light is due to keV electron beams
Explored auroral optical emissions, Ionosphere fields, currents, effects, etc.
GH = Global Hawk
Pr = Proteus
L = Lear Jet
Newman & Schoeberl, GSFC
Payload is proportional to font size (truncated at 2000 lb. and 600 lb.)
Bold indicates payload greater than 2000 lb.
Multiple requirements for cloud data
Vertical resolution data through atmosphere & into ocean
Almost universal OTH requirements
Real-time data to the scientist on the ground, at least for QA
Many, many missions with multiple, coordinated platforms
Interesting combinations of mother/daughter platforms, sondes
Intelligent, autonomous tracking of events or phenomena
Synergy with satellite activities.
Interagency Workshop for UAV Collaboration: 11 Proposals to Demonstrate UAV Enhancement of Science Objectives. 3 areas identified as high-value demonstration missions
High Impact Events
