A satellite in Earth Orbit

How Do Satellites Stay in Orbit? A Quick and Easy Guide

Gravity is the fundamental principle of orbits and Universe itself. But is it enough to explain the beautiful behavior of the celestial bodies? This article explains the fundamental principles of gravity, centripetal force and how they work together to keep satellites in orbit. Using clear, beginner-friendly language, it breaks down how Earth’s gravity pulls satellites inward while their forward motion creates a balanced centripetal force—resulting in stable orbits.

Mars colonization represented by a robot on Mars' surface

Mars Colonization: How Close Are We?

Humanity has long dreamed of setting foot on Mars—and staying there. In recent years, that dream has moved closer to reality, with major space agencies and private companies developing the technologies needed to send humans to the Red Planet. But while milestones like NASA’s Perseverance rover and SpaceX’s Starship prototype mark real progress, colonizing Mars remains a monumental challenge. From surviving deadly radiation to producing food and oxygen on a distant world, the path to a self-sustaining Martian settlement is still filled with technical, biological, and logistical hurdles. So, how close are we, really?

Why do Planets keep spinning?

Have you ever wondered why planets keep spinning and orbiting endlessly through space?
In this article, we uncover the cosmic forces set in motion billions of years ago — from the swirling birth of the solar system to the invisible rules of physics that still govern planetary motion today.
Discover the hidden principle that keeps worlds turning, the elegant simplicity behind their endless dance.

Artemis I

Artemis: the Future of Space Engineering Exploration

NASA’s Artemis program aims to return humans to the Moon and prepare for future missions to Mars. Using the Space Launch System (SLS) rocket and Orion capsule, Artemis will land the first woman and the next man on the lunar surface. Artemis is not just about revisiting the Moon—it’s about building a sustainable presence and paving the way for deep space exploration.
