Longer flights require systems with higher reliability
Unique systems for these longer flights are also required
The long duration Super Pressure flight systems are similar to those provided for the NASA LDB missions
CSBF has developed new systems as well as new unique systems for the long duration Super Pressure Balloon flights
Reliable solar power and charging systems for long flights
Flight control and data storage including redundant flight computers for telemetry, ballast, and terminate
Communication systems for line of sight as well as long duration flight
Other flight systems to support unique needs for Super Pressure Balloon flights including differential pressure measurement, environment measurements, tendon loads and more
Camera systems – smaller, lighter weight, fixed focal length, pan/tilt/zoom systems, and systems to obtain images from over the horizon on very long flights

Flight Trajectory Control
The potential for flight trajectory control will be an enabling technology for long Super Pressure Balloon flights
Typically a balloon floats along with the prevailing winds for the length of its flight
The goal of trajectory control is to slightly modify the balloon flight track over time to be able to steer the system to preferred flight latitudes
This would allow a balloon to be launch from one location and then to be shifted to a latitude band where there will be little population or land to overfly during the mission.
Toward the end of the mission, the balloon would be steered back to a desire location to safely terminate the flight and recover the science instrument.
Flight Trajectory Control is a long term advanced support system desired by the NASA Balloon Program Office
