Computational study on nitronium squarate - potential oxidizers for solid rocket propulsion?
Ammonium perchlorate combustion, nitronium squaric acid oxidizers
2010/12/29
The enthalpies of formation for solid ionic nitronium squarate, [NO2]2[C4O4], and covalent squaric acid dinitrate ester, O2N-C4O4-NO2, were calculated using the complete basis set (CBS-4M) method of P...

A quick test of the WEP enabled by a sounding rocket
WEP, EP equivalence principle general relativity sounding rocket
2010/12/20
We describe SR-POEM, a Galilean test of the weak equivalence principle, which is to be
conducted during the free fall portion of a sounding rocket flight. This test of a single pair of substances is ...

We describe a Galilean test of the weak equivalence principle, to be conducted during the free fall portion of a sounding rocket flight. The test of a single pair of substances is aimed at a measureme...
Rocket fuel research celebrated on anniversary of moon landing
rocket fuel moon landing Apollo
2009/7/20
When the lunar module took off from the surface of the moon 40 years ago Neil Armstrong and Buzz Aldrin were relying on 4 cubic tonnes of N2O4 — one of the most important rocket propellants ever devel...
The Auroral Turbulence II sounding rocket was launched into a moderately active night-side
aurora from the Poker Flat Research Range, Alaska, US. This unique three payload rocket experiment contained...
Generation of Magnetic Noise Bursts During Distant Rocket Launches
modification of the ionosphere Pc1 pulsations rocket-induced disturbances ionospheric MHD waveguide
2009/6/9
Bursts of hydromagnetic noises in the frequency range around 1 Hz after distant rocket launches have been detected at remote ground-based observatories. Theoretical model is suggested which interprets...

Rocket measurements positive ions polar mesosphere winter echo conditions
2009/1/21
On 18 January 2005, two small, instrumented rockets were launched from Andøya Rocket Range (69.3° N, 16° E) during conditions with Polar Mesosphere Winter Echoes (PMWE). Each of the rockets was...

rocket-borne particle mesosphere
2008/12/15
Meteoric smoke particles have been proposed as a key player in the formation and evolution of mesospheric phenomena. Despite their apparent importance still very little is known about these particles....
Low-frequency electrostatic waves in the ionospheric E-region: a comparison of rocket observations and numerical simulations
Ionosphere Space plasma physics
2017/3/22
Low frequency electrostatic waves in the lower
parts of the ionosphere are studied by a comparison of observations
by instrumented rockets and of results from numerical
simulations. Particular atte...
