‘Impossible’ Space Engine May Work: NASA

A controversial and puzzling engine design that could potentially make space travel much cheaper and faster may actually work, a new NASA study suggests.

The experimental propulsion system known as the EmDrive, which seems to violate the laws of physics, generated small amounts of thrust in a lab test, researchers said. The EmDrive, which was developed by British researcher Roger Shawyer over 10 years ago, generates thrust by bouncing microwaves around inside a cone-shaped chamber. 

According to Newton’s third law of motion — for every action, there is an equal and opposite reaction —  this should not work, because there is no exhaust expelled out of the EmDrive system.

However, researchers led by Harold White from NASA’s Johnson Space Centre in Houston, did measure some thrust. Their EmDrive variant produced about 1.2 millinewtons of force per kilowatt of energy, ‘Space.com’ reported. That is about 100 times more thrust than solar-sailing spacecraft — which harness the momentum of photons streaming from the Sun —  are able to achieve, researchers said.

Like solar sails, the EmDrive requires no propellant; a spacecraft equipped with this propulsion system could generate all the microwaves it needs using solar panels. It is believed that the EmDrive could make space travel much cheaper and faster, theoretically opening up the heavens to greater exploration.

However, the study is just a proof of concept and further testing is needed to definitively rule out all possible sources of experimental error, White said. PTI

Yet another example and the proof that we are developing in the field of science and technology at a very fast rate. I am feeling glad that we have developed such a space jet propulsion system. This will help us in future voyages across space.

  • About Us

Times Newspaper in Education (Times NIE) is a novel program that helps students ‘Stay Ahead’ and aims at making ‘Learning Fun’. It introduces concepts that help individual growth and development beyond school curriculum.

A brainchild of The Times of India, the world’s leading English newspapers, Times NIE nurtures progress and innovation. Adapted from the international concept, Times Newspaper in Education program (Times NIE) was initiated in India in 1985.

Today we have over 3000 schools and over 9 lac students subscribing to the programme, spanning 16 cities viz. Delhi, Mumbai, Pune, Bangalore, Kolkata, Chennai, Hyderabad, Ahmedabad, Kochi, Lucknow, Coimbatore, Chandigarh, Dehradun, Vijayawada, Visakhapatnam, and Jaipur.

The Times of India Student edition, a customized student newspaper exclusively for the students, packs a powerful punch in terms of content that leads to a smarter and superior learning experience. The information is crafted such that it finds use in classroom discussions, thus making it relevant and current. It truly gives education a new dimension by fostering the simple habit of reading which in turn paves the way for a confident, informed and aware individual. A newspaper that inspires young minds and equips them to face challenges of today’s world, making way for global citizens.

Empowering students with new cutting-edge knowledge through various educative and informative activities is a commitment and tradition of Times NIE. The programme serves as a catalyst of education and interaction, as well as a window into the minds of the quintessential Indian youth. On a significant scale Times NIE comprises diverse interesting activities and events that boost the child’s passion for learning, while revealing hidden talent.

While you are aware that The Times of India is among the leading English Newspapers across the world, it has consummated its position as an everlasting winner. With several international awards and recognitions to its credit, The Times of India and Times NIE have validated an enduring tradition of setting the highest benchmarks in every respect. We have been awarded with the two most prestigious awards, Times NIE - World’s No.1 NIE program and The Times of India, Student Edition - World’s No.1 Newspaper for the youth in 2006 by the celebrated World Association of Newspapers (WAN). In 2008 we were honoured by the International Newspaper Marketing Association (INMA), yet another international recognition for ‘Youth Audience Development’. In 2013 we were again honoured by the celebrated World Association of Newspapers (WAN) as the ‘Times NIE - World’s Best Youth Engagement Program’.

Times NIE has grown remarkably over the last three and a half decades, touching millions of children across more than 16 Indian cities. Our absolute commitment towards the fledgling generation remains undiluted and our greatest strength lies in the school partnership and commitment.
