Sustainability

By Suman Dutta, Research And Insights The aviation industry remains a central pillar of global connectivity and economic development, supporting more than 65 million jobs worldwide and contributing approximately 3.5% to global GDP. At the same time, it faces mounting pressure to reduce its environmental footprint and align its growth trajectory with the United Nations Sustainable Development Goals (SDGs). Commercial aviation accounts for roughly 0.9 billion tonnes of CO₂ emis

By Shreeja Dutta, Btech Biotechnology (Amity University) As the global aerospace industry grapples with the urgent need to decarbonize, the focus has traditionally remained on propulsion – how we burn fuel. However, any holistic approach to this nuanced problem requires an overview of the physical body of the aircraft itself. Conventional aerospace manufacturing is a high-waste, high-energy endeavor that relies on carbon-intensive materials and procedures. To truly build a s

By - Krishna, 10th class Priyadarshani Sen. Sec. School “The Universe is infinite But space has its limits… Space junk we’ve got.” — S. Thuy Nguyen-Onstott(NASA) One may ask, “What is orbital debris?” Even though we cannot see it from the ground, space junk is real and it is filling the Low Earth Orbit (LEO). LEO is now like an orbital junkyard, with millions of pieces of debris flying around Earth. Most orbital debris is human-made. It includes broken parts of spacecraft, us

By Archaic space missions relied on expendable launch vehicles, where rocket stages were single use entities. While effective, this approach resulted in high capital expenditure and limited launch frequency. Modern aerospace engineering has therefore, gradually veered towards reusable rockets and long-life spacecraft – enabling more sustainable and economical access to space. Reusable rockets are designed to recover and reuse key components. Achieving reusability requires

By Space sustainability refers to the effort to preserve Earth’s orbital environment so that space can remain accessible for exploration, scientific discovery, and technological development for generations to come. It is not merely a technical challenge but also an ethical responsibility. Outer space has long been regarded as the shared domain of humankind, and maintaining its accessibility requires careful stewardship rather than unchecked exploitation. In recent decades, hu

by Sanskriti Sinha, College of Vocational Studies (DU) The outer space is an expanse that has proved to be hostile to life forms and machines alike. Negative temperatures and harsh solar radiation invite careful consideration and special measures towards all who attempt to navigate it. Yet some spacecraft continue to travel, send messages, and serve humanity decades after launch. These long-life spacecraft are not just machines — they are enduring companions in our journey t

By Chetan Parshuramka, 1st year, Amity Institute of Aerospace Engineering There existed a time when space was a vast expanse, untouched by human activity and openly hostile to it. When Sputnik-1 rose as the first successful human attempt to breach this frontier, it did not merely usher in an age of exploration—it marked the expansion of the scientific frontier itself. In the decades that followed, satellites were added to orbit at an accelerating pace, justified by the capabi
