D. Launching Services
During the course of the project balloon .flights were split into·
two general classifications, (a) research and (b) service.
Research flights were made to test balloon contrOls and telemeter-
ing systems developed under the contract.· A .tul.l report of these
research flights has been mac!e 1ft "Technical Report 9.3.02 1),

Service fiights were carried out by New York UniTersit7 personnel
in conjunction with technical personnel from the sponsoring ageney
to test geophysical equipnent deTeloped in Air Force laboratories.
The requirements for these fiights wre launching and tracking
of balloons to float at specified altitudes for short periods of
time (6 to 8 hours). Because of this short .tl.ight ·duration,
simplified plastic balloon STStas wre used. Balloons were
maintained aloft by ,,se of constant fixed ballast now, or ballast
was excluded entirely from the 87Stem. A typical night using
constant ballast flow at a rate slightl7 exceeding leakage losses
is shown as Fig. 8.
