Analysis of tethered balloon, ceilometer and class sounding data taken on San Nicolas Island during the FIRE project

During the FIRE Marine Stratocumulus Program on San Nicolas Island, Colorado State University (CSU) and the British Meteorological Office (BMO) operated separate instrument packages on the NASA tethered balloon. The CSU package contained instrumentation for the measurement of temperature, pressure, humidity, cloud droplet concentration, and long and short wave radiation. Eight research flights, performed between July 7 and July 14, are summarized. An analysis priority to the July 7, 8 and 11 flights was assigned for the purposes of comparing the CSU and BMO data. Results are presented. In addition, CSU operated a laser ceilometer for the determination of cloud base, and a CLASS radiosonde site which launched 69 sondes. Data from all of the above systems are being analyzed.

Project Fire photographic summary and record of reentry phenomena at hyperbolic velocities

Project Fire was undertaken by the National Aeronautics and Space Administration to measure the total and radiative heating experienced by a blunt body reentering the earth's atmosphere at 11 300 meters per second. This report presents a photographic record of the Fire II spacecraft during its reentry. The photographs were clear enough to establish the times of major events, and they show that adequate-separation was maintained between the reentry package and the spent Antares. This report also identifies operational problems encountered in spacecraft reentry at hyperbolic velocities and presents the solutions satisfactorily employed.
