TL;DR: In this paper, a diode laser system optimized for laser cooling and atom interferometry with ultra-cold rubidium atoms aboard sounding rockets is presented as an important milestone toward space-borne quantum sensors.
Abstract: We present a diode laser system optimized for laser cooling and atom interferometry with ultra-cold rubidium atoms aboard sounding rockets as an important milestone toward space-borne quantum sensors. Design, assembly and qualification of the system, combing micro-integrated distributed feedback (DFB) diode laser modules and free space optical bench technology, is presented in the context of the MAIUS (Matter-wave Interferometry in Microgravity) mission. This laser system, with a volume of 21 l and total mass of 27 kg, passed all qualification tests for operation on sounding rockets and is currently used in the integrated MAIUS flight system producing Bose–Einstein condensates and performing atom interferometry based on Bragg diffraction. The MAIUS payload is being prepared for launch in fall 2016. We further report on a reference laser system, comprising a rubidium stabilized DFB laser, which was operated successfully on the TEXUS 51 mission in April 2015. The system demonstrated a high level of technological maturity by remaining frequency stabilized throughout the mission including the rocket’s boost phase.

TL;DR: In this article, high-resolution electric field and particle data, obtained by the S23L1 rocket crossing over a discrete prebreakup arc in January 1979, are studied in coordination with ground observations (Scandinavian Magnetometer Array, TV and all-sky cameras) in order to clarify the electrodynamics of the arc and its surroundings.

TL;DR: In this paper, the use of hydrides as additives in hybrid fuels and solid propellants was investigated and a comparative analysis of theoretical performance of gravimetric and volumetric specific impulse, propellant average density, adiabatic flame features, and preliminary estimate of exhaust products was conducted.

TL;DR: A search for X-ray emission from galactic objects on April 29, 1963, disclosed two localized sources, one of which appeared in Scorpius and the other in the direction of the Crab Nebula as discussed by the authors.
Abstract: A SEARCH for X-ray emission from galactic objects on April 29, 1963, disclosed two localized sources, one of which appeared in Scorpius and the other in the direction of the Crab Nebula. The observations were made with a proportional counter flown in an Aerobee rocket from White Sands, New Mexico.
