As of May 2021, there are about 4,300 active artificial satellites currently orbit Earth. We rely so much on satellites for so many things in our lives, and we count on them to be durable and reliable. When satellites don’t work properly, they can severely impact our lives. That’s why …

Satellite communication is a technology that is used to transfer the signals from the transmitter to a receiver with the help of satellites. Communications via satellite have the unique characteristic of the ability to cover the globe with a flexibility that cannot be duplicated with terrestrial links. Mobile satellite service …

The modern space industry is witnessing exponential growth in small satellite and nanosatellite areas. Nanosatellite and microsatellite refer to miniaturized satellites in terms of size and weight, in the range of 1-10 Kg and 10-100 kg, respectively. ‘CubeSat’ is one of the most popular types of miniaturized satellites. These are …

Two out of three missions to the red planet have failed. One reason there have been so many losses is that there have been so many attempts. “Mars is a favorite target,” says Dr. Firouz Naderi, manager of the Mars Program Office at the Jet Propulsion Laboratory. To get there, …

The UK has a thriving space industry that generates an income of £14.8 billion [$20.57 billion] each year. The UK Space Agency’s aim is to drive growth into the UK economy by supporting the development of space technology and skills, as embodied in the UK Space, Innovation and Growth Strategy (Space …

As the space domain has become more congested, the potential for intentional and unintentional threats to space system assets has increased.
