Just 5 years after Sputnik, on 18 August 1962, Norway launched the first sounding rocket from Andøya in northern Norway. The establishment of Andøya Rocket Range (ARR), in the Arctic and right in the middle of the night-time auroral zone, gave t

A new rocket range, SvalRak, was opened in November 1997 at Ny-Ålesund (79°N) in the Svalbard archipelago. The first instrumented rocket was launched on 20 November, 1997, at 1730 UT during geomagnetically quiet conditions. The payload was instr

Using a one-dimensional, time-dependent model that solves the coupled continuity and momentum equations for an arbitrary number of charged and neutral particles species, we study how the ambient plasma near the polar summer mesopause responds to the

Exposure to fluorides can induce inflammatory reactions, cell cycle arrest, and apoptosis in different experimental systems. Fluorides are known G-protein activators, but less is known about fluoride effects downstream of G-protein activation. The ai

We report the results from simultaneous radar and rocket measurements of a PMSE event where for the first time the rocket measured dust and plasma within the radar beam. We find very clear correspondence between the measured dust charge density profi

We present a new rocket instrument which measures total atmospheric density with great precision and resolution by Rayleigh scattering of infrared light. Comparison with a ground-based lidar shows: (a) both instruments measure the same physical param

During the ECHO campaign in 1994 neutral and electron density fluctuations were measured together with charged aerosols on the same sounding rocket launched close to a VHF radar detecting polar mesosphere summer echoes (PMSE). For the first time this

Results from the first direct rocket probe measurements of the currents due to impacting mesospheric dust are reported. The observations which are corrected for production of secondary electrons during impact show that dust is a major charge carrier

During the METAL campaign conducted at Andoya Rocket Range in September-October 1991, detailed in situ measurements were performed by means of plasma probes in the TURBO rocket payload. During one of the salvoes (30 September 1991), strong plasma den

Some theories for the observed anomalous radar backscatter during the summer (polar mesospheric summer echoes, or PMSE) and electron bite outs measured by rockets require the presence of charged dust. To investigate this, two dust probes have been la
