The threat of an asteroid colliding with Earth is a real and potentially catastrophic danger. While the probability of a large asteroid impact in our lifetimes is low, the consequences could be devastating, causing widespread destruction and loss of life. Fortunately, scientists and engineers are developing a range of planetary defense strategies to detect and deflect hazardous asteroids before they reach Earth. This article explores the various methods being researched and tested to protect our planet from asteroid impacts ..read more

Spaceports are the critical infrastructure that enable access to space, serving as the gateway for launching satellites, spacecraft, and humans into the final frontier. As the commercial space industry continues to grow and evolve, the need for well-planned and efficiently developed spaceports has become increasingly important. Spaceport master planning is a comprehensive process that involves defining the long-term vision, goals, and strategies for the development and operation of a spaceport. This article explores the key elements of spaceport master planning and the phased approach to devel ..read more

Magnetic fields are ubiquitous in the universe, permeating planets, stars, galaxies and the vast expanses of intergalactic space. Among the most fascinating and extreme examples of magnetic phenomena are the magnetic stars. These stellar objects possess powerful magnetic fields that shape their evolution, appearance, and interactions with their surroundings. From the relatively calm and stable magnetic fields of main sequence stars like our Sun, to the mind-bogglingly intense fields of exotic magnetars, magnetic stars come in a wide variety of types. Understanding these stars provides key insi ..read more

The H-R diagram was independently created around 1910 by Ejnar Hertzsprung and Henry Norris Russell, plotting stars' absolute magnitudes or luminosities against their colors or temperatures. It shows that stellar properties are not random but follow distinct patterns ..read more

The Boeing CST-100 Starliner represents a significant shift in the approach to spacecraft recovery upon returning from orbit. Unlike many previous crewed spacecraft that relied on ocean splashdowns, the Starliner is designed to touch down on solid ground. This innovative decision stems from a combination of factors, including safety considerations, logistical advantages, and a desire to streamline the post-mission recovery process ..read more

The Boeing CST-100 Starliner is a next-generation crew capsule designed to transport astronauts to and from low Earth orbit destinations such as the International Space Station (ISS). Developed in partnership with NASA's Commercial Crew Program, the Starliner represents a major milestone in the commercialization of human spaceflight. With its innovative design, advanced technologies, and focus on crew safety and comfort, the Starliner aims to usher in a new era of reliable, cost-effective access to space ..read more

The universe is vast, a tapestry of stars, galaxies, and untold numbers of planets. Driven by a profound curiosity, humanity has long asked the question, "Are we alone?" As our technology advances and our understanding of the cosmos deepens, it seems increasingly plausible that the answer could be no. But what might extraterrestrial life look like ..read more

For centuries, humanity has gazed upon the night sky with wonder and curiosity. The stars have guided our journeys, inspired our art, and fueled our scientific discoveries. However, the pristine beauty and clarity of the celestial sphere are increasingly threatened by a modern marvel of technology: Low Earth Orbit (LEO) satellite mega-constellations ..read more

Millions of Americans still don’t have access to high-speed internet. Christopher Ali, a professor of telecommunications at Penn State University, discusses who lacks access to broadband and how the federal government – with a US$65 billion commitment – is trying to bring more people online ..read more

The Industrial and Technological Benefits (ITB) Policy is a powerful tool designed to leverage Canada's defence and security procurement to drive economic growth, create jobs, and foster innovation across the country. This policy requires companies awarded major defence contracts to undertake business activities in Canada equal to the value of their contracts, ensuring that the nation receives substantial economic benefits from its investments in defence and security ..read more
