A Concept of Suborbital Scientific Mission and Technology Validation

Abstract

Suborbital platforms are one of alternatives for satellites. They offer cheaper access to space to perform broad range of scientific and technology R&D. One of suborbital platforms are sounding rockets, which are suitable for these applications. A concept of scientific mission utilizing the sounding rocket is presented by author in this paper. The novelty of this mission is the operational responsive launch approach, which presents the example of the mission which responds for payload user needs, not payload contest approach, which is often in scientific community competing for payload space in space agency sounding rocket launch campaigns. The main mission goal is to perform astronomical observation of NEO using IR/VIS telescope. The secondary goal is to qualify the instrument for use on astronomical satellite observatory and raise its technology readiness level from TRL 6 to TRL 8. The expected mission output is to gain scientific data on NEO object and perform new IR/VIS optoelectronic instrument technology validation.

Use of Modern Technology to Develop Investment Housing Projects in Iraq

Abstract

The problem of housing is one of the most important problems in Iraq, especially with the increase in the rate of population growth which is one of the highest rates in the world and after the great destruction that happened in Iraq because of wars and terrorist acts, and here begins to think about the real solutions of this crisis using modern technology and taking into account the feasibility of using modern construction materials compared to the traditional method of construction.

Investors are seriously considering changing the traditional building style and transition to modern building materials to increase quality, win a time, ease of installation and achieve dimensional consistency with ease of internal and external finishing work. The hot weather in Iraq requires real attention to the issue of thermal insulation of buildings and therefore can use the advantage of modern materials to increase thermal insulation and reduce in the energy consumption. This article sheds light on the investment housing projects in Baghdad city.
