With Mars colonisation becoming a reality for the near future, it is of importance to analyse how crew and cargo can be transported between Earth colony on Mars. This article feasibility design study launch vehicle whose mission shuttle from Low Orbit Martian surface. A single-stage reusable rocket has been selected fulfil this mission, code-named Charon. The profile such was created, leading M...
Future reusable launch vehicles will depend on new propulsion technologies to lower system operational costs while maintaining adequate performance. Recently, a number of vehicle systems utilizing rocket-based combinedcycle (RBCC) propulsion have been proposed as possible low-cost space launch solutions. Vehicles using RBCC propulsion have the potential to combine the best aspects of airbreathi...
A numerical dynamic-aerodynamic interface for simulating the separation dynamics of constrained strap-on boosters jettisoned in the atmosphere is presented. A 6-DOF multi body dynamic solver ،using Constraint Force Equation Methodology is coupled with a numerical time dependent Euler flow solver. An automatic dynamic mesh updating procedure is employed using smoothing and l...
Pea forms symbiotic nodules with Rhizobium leguminosarum sv. viciae (Rlv). In the field, pea roots can be exposed to multiple compatible Rlv strains. Little is known about the mechanisms underlying the competitiveness for nodulation of Rlv strains and the ability of pea to choose between diverse compatible Rlv strains. The variability of pea-Rlv partner choice was investigated by co-inoculation...
The NASA Exploration Systems Architecture Study (ESAS) produced a transportation architecture for returning humans to the moon affordably and safely. ESAS determined that the best lunar exploration strategy was to separate the launch of crew from the launch of cargo, thereby requiring two launches per lunar mission. An alternate concept for the cargo launch vehicle is a side mounted Shuttle-der...
The United States Air Force and Orbital Sciences Corporation (Orbital) completed development and demonstration of a new low cost space launch vehicle for launching small satellites using surplus Minuteman II rocket motors melded with commercial launch vehicle technology. The Orbital Suborbital Program Space Launch Vehicle (OSPSLV, aka OSP Minotaur) successfully achieved all mission objectives w...
