“…For reasonable values E ≈ 2 · 10 8 J (if Р ≈ 10 MPa and volume V ≈ 20 m 3 ) and ρ ~ 10 −10 kg/m 3 , we find that the shock wave speed is about 2 ⋅ 10 3 ⋅ t − 3/5 m/s. Therefore, if the number of solid particles is not too large (i.e., the shock wave energy is considerably larger than kinetic energy of the dispersed particles), they can be accelerated up to a speed of the order of 2 · 10 3 m/s in the first seconds of the expansion [ Platov et al , ]. This estimate corresponds well to the observed speed of the void expansion [ Spell , ].…”

“…The Russian military missile “Bulava” is a three‐stage solid propellant 36 metric tons ballistic rocket. Its solid fuel contains aluminum [ Platov et al , ], while such solid propellants also include an oxidizer (e.g., ammonium perchlorate, NH 4 ClO 4 ) and a binder‐like polyurethane [ Silant'yev , ]. On 9 December 2009, a test launch was performed from a submarine located in the White Sea (see map in Figure ).…”

“…Optical observations of the missile explosion [ Platov et al , ] showed a distinctive turquoise color, which was caused by the molecular resonant sunlight scattering at the aluminum monoxide molecules (AlO). In the context of meteor ablation and metal ions chemistry [ Brasseur and Solomon , ; Plane , ], ionization of these molecules and their products by sunlight, and other quick reactions, occur.…”

We report on ionosonde and meteor radar observations made in Sodankylä Geophysical Observatory (SGO, 67°22′N, 26°38′E, Finland) on 9 December 2009, during a test launch of the Russian solid propellant military missile. Due to a technical problem, the missile was self-destroyed around 07 UT at an ionospheric height (near 200 km altitude) over the Kola Peninsula (Russia), at a distance about 500 km to east from the observatory. Products of the explosion were spread into a large area and reached the region of SGO meteor radar observations in about 2 h (around 09 UT). After about 3 h (around 10 UT), a sporadic E layer presumably composed of the remains including long-lived metallic (aluminum and its oxides) ions, was observed near the zenith of the SGO ionosonde. We discuss possible mechanisms accounting for transport of the remains. (1) Since the event occurred during a long-lasting period of extremely low solar and magnetic activity, the ionospheric electric field was unlikely to play a substantial role in the transport of the remains and sporadic E layer formation. (2) The horizontal transport of the remains cannot be explained by the neutral winds based on empirical models. (3) Theoretical estimations suggest that the observed transport could be due to thermospheric turbulence.

“…The luminosity of a thin, expanding spherical layer can be caused by not only sunlight scattering by the dispersed component but also by a temperature jump at the shock front (Platov et al, 2013). At distances reaching several tens of kilometers from an explosion center, the temperature at the shock front will be higher than ~1000 K, which is sufficient to excite luminosity in the optical band.…”

The velocity of spherical gas-dust cloud expansion in the situation when the stages of solid propellant rocket separate in the upper atmosphere have been determined. The measured velocity vary from 2.5 to 7.5 km/s. The dispersed component accelerates at the front of a shock that develops at engine thrust shutdown. The model calculations of the gas-dust cloud luminosity intensity qualitatively coincide with the photometric profiles of object images. Such formations can vary from almost homogeneous ball shaped clouds to rather thin spherical shells depending on the gas-dust cloud mass and the matter distribution within this cloud.

On 9 December 2009 at about 07 UT a solid propellant 36.8 t ballistic rocket was self‐destroyed at an altitude of 170–260 km, at a distance of about 500 km to the east of Sodankylä Geophysical Observatory (SGO, 67°22′N, 26°38′E, Finland). After 2–3 h the SGO meteor radar (operating at a frequency 36.9 MHz) received unusual echoes, which indicate turbulence of ionospheric plasma (irregularities of electron density) with a temporal scale on the order of 0.1 s and a spatial scale of a few to tens of meters. The turbulence occurred at a height of about 80 km and was localized in several areas of about 60 km in horizontal scale. Line‐of‐sight velocity of the irregularities was up to a few tens of meters per second toward the radar. The event occurred in the winter high‐latitude mesosphere during extremely low solar and geomagnetic activity. Aerosol particles caused by the missile explosion played a key role in producing the electron density irregularities. As a possible explanation, we suggest that sedimented by gravity and, hence, moving with respect to the air, charged aerosol particles (presumably composed of aluminum oxide) might produce meter‐scale irregularities (electrostatic waves) via dissipative instability, which is a mechanism analogous to that of the resistive beam‐plasma instability.
