Two Types of Balloons

Zero-Pressure (ZP) Balloon changes volume due to radiative input

• Used for Conventional Flights and Polar LDB Flights

Super Pressure Balloon maintains nearly constant volume – under development

Allows Ultra Long Duration Balloon (ULDB) Flights

Provides stable altitude Long Duration Balloon (LDB) flights at mid-latitudes

Super Pressure Development

Several science groups are requesting a suspended weight of 5,500

pounds on the 18.8 MCF; therefore, some future test flights will have higher

suspended weights when appropriate.

• The NASA SPB is being developed to provide a stable platform at constant

density altitude for extended duration science investigations at polar and

mid-latitudes

• An incremental approach has been applied to the development.

Environmental Considerations

• WFF Completed a Biological Evaluation

and Environmental Assessment for SPB

(ULDB) Program Southern Hemisphere

Flight Operations covering Antarctica

and New Zealand-launched SPBs.

• The Program received a Finding Of No

Significant Impact and has received

approval from NASA and concurrence

from NOAA and NSF to proceed with

Operations.

• The stratospheric anticyclone over

Antarctica provides a stable balloon

trajectory, once the anticyclone breaks

down trajectories are highly variable.

• Increased operational area (more

northern latitudes) for 2017 mission.

• In the event of ocean

termination, the entire balloon

system will be valve downed to

the water surface and

submerged.

Safety Considerations

• Trajectory Analysis Pre-Launch

• Airport Closed During Launch

Operations

• Roadblocks

• Go-No Go prior to Land Mass

• Go-No Go ~ every 24 hour when

over land

• Wanaka team will monitor and

support flight from launch pre-

ops to end of LOS

• Palestine Operations Control

Center will be online at launch

and take over after leaving LOS

capabilities in Wanaka

• SPB team will monitor the entire

flight remotely

• Palestine Operations Control

Center will be manned 24 hours

from launch until termination

• Science typically monitors from

home institution
