There is global space race among countries to build Moon bases, harness it’s mineral resources and helium-3, fuel for future nuclear fusion power plants. Space agencies in US, China, Japan, Europe, Russia, Iran , Canada and a few private companies all hope to send people to the moon by as …
Read More »Recently many companies have launched large constellations of satellites to deliver broadband Internet to serve nearly 2 billion people around the world that live in areas that lack mobile coverage, mostly far from major cities, which makes building a network of terrestrial cell towers to connect them prohibitively expensive. These …

The ground station system coordinates the communication process with satellites in space. A communications satellite is an artificial satellite that relays and amplifies radio telecommunications signals via a transponder; it creates a communication …

Multiple countries are developing the ability to mine in space, specifically on the moon and on asteroids. The moon stands out as a nearby example of what will soon be the site of regular operations. The moon is home to hundreds of billions of dollars-worth of natural resources, including helium-3, …

Quantum technology (QT) applies quantum mechanical properties such as quantum entanglement, quantum superposition, and No-cloning theorem to quantum systems such as atoms, ions, electrons, photons, or molecules. Quantum technologies are already revolutionizing life on Earth. But they also have the potential to change the way we operate in space. …

They utilize frequency reuse and multiple spot beams to deliver vast throughput for the same amount of allocated orbital spectrum. The increase in capacity typically ranges from 2 …
Read More »Traditionally, the satellite industry has relied on geosynchronous earth orbit (GEO) satellites that take years to build and require very expensive launches to deliver them to orbit. Satellite networks using geosynchronous equatorial orbit (GEO) are effective at providing stationary coverage to a specific area, however, Latency issues due to the …

There has been an exponential growth of space objects, including orbital debris that has increased the in-orbit collision risk. NASA estimates there are 21,000 objects orbiting Earth that are larger than 10 cm, 500,000 between 1 and 10 cm, and more than 100 million that are less than 1 cm. …
