Muons are subatomic particles that behave a lot like electrons but are around 200 times heavier. As the US Department of Energy explains, “Muons created in the atmosphere constantly hit every inch of the Earth’s surface and pass through almost any substance.”   Many scientists have noted that measuring the …

The first space age is considered to be started in 1957. The 20th-century space race between the USA and the USSR was primarily a military technological competition. Each strove to be the first to launch satellites or land on the Moon, while the rest of the world looked on. In …

There has been an exponential growth of space objects, including orbital debris that has increased the in-orbit collision risk. In the year 2019 alone, 385 smallsats were launched reaching a value close to 2900 in mid-2020 and still rapidly increasing. Moreover, taking into account all the applications filed by satellite …

Most spacecraft propulsion concepts can be classified into two categories: chemical and electric. Chemical propulsion relies on chemical reactions and can produce high thrust, but requires a large amount of fuel. Electric propulsion uses electromagnetic fields to accelerate ionized gases and is very fuel-efficient, but produces small amounts of thrust …

The definition, management, and control of interfaces are crucial to successful programs or projects. Interface management is a process to assist in controlling product development when efforts are divided among parties (e.g., Government, contractors, geographically diverse technical teams, etc.) and/or to define and maintain compliance among the products that should …

Mechanical engineering is an engineering branch that combines engineering physics and mathematics principles with materials science, to design, analyze, manufacture, and maintain mechanical systems It is one of the oldest and broadest of the engineering branches.   “Mechanical Engineering takes in all built structures and moving parts flown in space, …

There is growing utilization of miniaturized satellites for military and defense applications.  Defense organizations have been launching communication nanosatellites and microsatellites to provide communication signals to soldiers stationed in remote locations or in dense forests. The military needs more data bandwidth and reliable communications infrastructure for its UAVs, which can …

Wire harnesses are bundled assemblies of cables and connectors, that are used to transmit signals and power between components. If we could compare a satellite to the human body, the electrical harness would represent the blood vessels conveying the power and the nervous network transmitting the commands and sensor information …
