Predicting emissions under rarified flow conditions remains a challenge. Two rocket experiments (at 3.5 and 5 km/s) obtained the UV data under flight conditions using onboard instruments; the greatest discrepancies in the predictions occurred at the

A rocket‐borne system to measure air density by detecting Rayleigh‐scattered light from an onboard light source is described. The system utilized a high intensity mercury arc lamp to produce a modulated light beam. Light scattered from air molecu

The report is primarily concerned with the instrumentation of a Paiute-Tomahawk rocket which was launched to measure the magnitude and direction of electric fields in and over an auroral arc. In addition, other instruments aboard made measurements of

A completely automatic chemiluminescent instrument has been developed for in situ measurements of NO in the stratosphere. Signal intensity is linear in NO. Typical responsivity at 21.3 km is 1860 counts/sec ppbv. With a 1 sec measuring time constant,
Six instrumented rockets were used to probe three separate ion clouds that resulted from F-region barium releases, and measure electron density structure within the clouds. Two probes were launched into each of the three ion clouds, and each probe sh
