Boeing X-37 Mystery Mission

The U.S. Air Force's unmanned space plane X-37 is one of the most mysterious spacecraft ever. It is known as the Orbital Test Vehicle and its primary objective is to test advanced spacecraft technologies. The program is classified, therefore it remains a secret what the tested technologies are. The X-37B was launched on 20 May 2015, this is the fourth X-37 mission and it is still in progress. The X-37B space plane has been in orbit for almost two years now and broke an orbital record when it hit 675 days in orbit around Earth on March 25th 2017.

NASA’s EO-1 Retires After 17 Years

Earth Observing-1 (EO-1), one of NASA’s pathfinder Earth satellites, was launched back in 2000 as part of their New Millennium Program. Its original mission was designed to last one year and it was designed to operate for about 1.5 times that duration. Seventeen years later, we can safely say that it has far exceeded expectations. Now EO-1 is finally set to retire on March 30, 2017. Some of its achievements include being the first to map active lava flows, track re-growth in the Amazon and measure a methane leak at a facility from space. During its operation, more than 1500 papers were published based on EO-1 research.

Endless runways: The future?

If you think that everything you can think of has already been invented, you are wrong. Recently BBC News posted a film [1] presenting the idea of circular runways. The Endless Runway is a project run by the NLR in the Netherlands. The principle of The Endless Runway is that aircraft take-off and land on a circular runway. The circular runway will allow aircraft to take-off in any direction and land in any direction, making it possible for the aircraft to always land and take-off in the most desirable direction with respect to the wind: headwind. The possibility for aircraft to land and take-off without experiencing crosswind at all times is not the only advantage to the concept of circular runways. In low wind conditions, it would be possible to shorten the landing and take-off intervals....
