Unmanned Air Vehicles (UAVs) and other relatively small airborne platforms are being increasingly pressed into service to perform broadband Intelligence, Surveillance and Reconnaissance (ISR) missions. Typically, these smaller platforms do not have enough space for a dish antenna and gimbal mechanism needed for a high-data-rate telemetry link. This paper presents a unique approach to steering a...

The rank-ordered multifractal analysis (ROMA), a recently developed technique that combines the ideas of parametric rank ordering and one-parameter scaling of monofractals, has the capabilities of deciphering the multifractal characteristics of intermittent fluctuations. The method allows one to understand the multifractal properties through rank-ordered scaling or nonscaling parametric variabl...

Evaporation of a pure liquid into a inert gas is studied theoretically and experimentally. In contrast with the case where the gas phase is made of pure vapor, the thermocapillary (Marangoni) effect strongly destabilizes the system, and results in intensive and often chaotic forms of interfacial convection. Theoretically, a generalized one-sided model is proposed, which allows to solve thermo-h...

Several studies have shown that altered gravity conditions influence mammalian cell growth and differentiation. The molecular mechanisms underlying these effects, however, remain relatively obscure. In this paper we show that microgravity reached in a sounding rocket strongly decreases epidermal growth factor (EGF)-induced expression of the proto-oncogenes c-fos and c-jun, which are both implic...

The Very-high-resolution Advanced ULtraviolet Telescope (VAULT) experiment was successfully launched on 7 May 1999 on a Black Brant sounding rocket vehicle from White Sands Missile Range. The instrument consists of a 30 cm UV diffraction limited telescope followed by a two-grating, zero-dispersion spectroheliograph tuned to isolate the solar Lα emission line. During the flight, the instrument s...

Abstract Bose-Einstein condensates (BECs) in free fall constitute a promising source for space-borne interferometry. Indeed, BECs enjoy slowly expanding wave function, display large spatial coherence and can be engineered probed by optical techniques. Here we explore matter-wave fringes of multiple spinor components BEC released employing light-pulses to drive Bragg processes induce phase impri...

The Meridian Project’s sounding rocket mission uses a mass spectrometer to conduct in-situ atmospheric detection. In order assess the influence of surface material outgassing and attitude control jet on spectrometer’s detection, platform was modeled simulated. Using physical field simulation software COMSOL Monte Carlo method, this study investigated whether gas molecules from two cases could e...

This paper presents Rocket Experiment (REX) that was part of a dual payload rocket campaign for NASA's sounding Black Brant IX with water recovery technology. mission suborbital flight launched and recovered on April 4, 2018 targeted the Vela supernova remnant. The purpose REX to classify Technology Readiness Level onboard devices designed space applications. were two wide-field X-ray telescope...
