Spacecraft are man-made machines that operate in space. An orbiting spacecraft is normally referred to as a satellite, although it is manmade as opposed to a natural satellite like our moon. A spacecraft is typically subdivided into two major parts, the payload and the bus.   Where the mission can …

The function of the propulsion system is to produce thrust, which is the force that moves a rocket through air and space. Different propulsion systems generate thrust in different ways, but always through some application of Newton’s third law of motion. In any propulsion system, a working fluid is accelerated …

Introduction: Diminishing Manufacturing Sources and Material Shortages (DMSMS) pose significant challenges for industries worldwide, and the Department of Defense (DoD) is no exception. As a major procurer and user of advanced technologies and equipment, the DoD faces the constant risk of obsolescence and material shortages. However, the DoD has implemented …

Introduction Material science has always been at the forefront of human innovation, driving advancements in various industries. With the emergence of synthetic biology, a new era of material development has begun. By harnessing the power of living organisms and their ability to engineer complex molecular structures, scientists are revolutionizing material …

A photonic integrated circuit (PIC) or integrated optical circuit is a device that integrates multiple (at least two) photonic functions and as such is similar to an electronic integrated circuit. The major difference between the two is that a photonic integrated circuit provides functions for information signals imposed on optical …

Although universal fault-tolerant quantum computers – with millions of physical quantum bits (or qubits) – maybe a decade or two away, quantum computing research continues apace. It has been hypothesized that quantum computers will one day revolutionize information processing across a host of military and civilian applications from pharmaceuticals discovery, …

In the UK, there are some 7,000 people on the list who are in dire need of organ transplants and In the US, the number awaiting transplant is around 120,000, with 20 dying each day for want of an organ. There is a large and growing need for an alternative to …

3D printing or additive manufacturing is ongoing revolution in manufacturing with its potential to fabricate any complex object and is being utilized from aerospace components to human organs, textiles, metals, buildings and even food. Additive manufacturing is defined by ASTM International as the process of joining materials together, layer by …
