| Zusammenfassung |
| Three sounding rockets were launched from Andøya Rocket Range in the ECOMA
campaign in December 2010. The aim was to study the evolution of meteoric
smoke particles during a major meteor shower. Of the various instruments
onboard the rocket payload, this paper presents the data from a multi-Needle
Langmuir Probe (m-NLP) and a charged dust detector. The payload floating
potential, as observed using the m-NLP instrument, shows charging events on
two of the three flights. These charging events cannot be explained using a
simple charging model, and have implications towards the use of fixed bias
Langmuir probes on sounding rockets investigating mesospheric altitudes. We
show that for a reliable use of a single fixed bias Langmuir probe as a high
spatial resolution relative density measurement, each payload should also
carry an additional instrument to measure payload floating potential, and an
instrument that is immune to spacecraft charging and measures absolute plasma
density. |
