AB: Electric field and potential perturbation measurements were successfully conducted during two rocket flights from Andoya, Norway in August 2007. The MASS rockets were launched through small to moderate noctilucent cloud and polar mesospheric summer echo events. The identical electric field instruments on each of the MASS rockets included two pairs of booms, forward and aft in the same plane, with two high impedance probes on each boom for a total of eight probes per rocket. Double Langmuir probe measurements were made between all pairs of probes, and involved probe separations from 0.65m to 3.0m both perpendicular and parallel to the rocket axis. After deployment, and below the NLC the electric field probes detected the expected VxB electric field in the rocket frame of reference. Initial analysis indicates that significant voltage perturbations were detected on the first flight during a separated, lower NLC layer, and during a larger, higher altitude PMSE layer. The second flight found similar perturbations during encounter with a PMSE layer. During the PMSE traversal of flight 1 it appears that the rocket became positively charged by about one Volt relative to the external probes, coincident with the aerosol particles.
