The vibrational temperature (T v ), the rotational (T r ) and the number density of atmospheric molecular nitrogen (N 2 ) were measured in situ by a sounding rocket S-310-30 in order to study the dynamics and energetics in the lower thermosphere. Atmospheric N 2 was ionized and excited using an electron gun and the emission from N 2 + 1st negative (1N) bands was measured by a sentive spectrometer. T v and T r were determined by fitting the improvements of the instrument and the preliminary results of the measurement are presented.
