The Evolution of Aerospace Engineering: From Wright Brothers to Mars Rovers Link to heading

Aerospace engineering has come a long way since the Wright brothers first took to the skies in 1903. From those humble beginnings, we have reached the astounding capability of landing rovers on Mars and sending spacecraft beyond our solar system. This post takes you on a journey through the significant milestones in aerospace engineering, highlighting the technological advancements that have shaped our understanding of flight and space exploration.

The Wright Brothers: Pioneers of Aviation Link to heading

On December 17, 1903, Orville and Wilbur Wright achieved the first powered, controlled flight with their aircraft, the Wright Flyer. This monumental event marked the beginning of modern aviation and set the stage for future innovations. The Wright brothers' success was due to their meticulous approach to understanding aerodynamics, control, and propulsion.
