Robert Kennedy spoke on "Interstellar Flight This Century" at Oak Ridge League lunch. He is presenting a paper at a D.C.

There has been huge progress on laser pushed sails. Laser pushed sails appear to be a path to sending probes up to 20% of the speed of light when we can make 1 gram sails that are one to two meters on ...

Quick: what’s the most successful, stable, one-design dinghy class in world history? Answer: the Laser, of course, now rolling past 200,000 boats worldwide. In fact, in celebration of this milestone, ...

The universe is big, staggeringly, mind-bendingly big. There are trillions and trillions of stars in the observable universe but traveling to even the closest one with our best rockets would take tens ...

Greg Matloff and his wife, C Bangs, have researched the use of holographic films for solar and laser pushed space sails. Matloff’s work is described at Centauri Dreams. Greg Matloff is on the ...

An interstellar mission to a black hole may sound impossibly bold, yet a new concept by astrophysicist Cosimo Bambi of Fudan University outlines how a tiny, laser‑propelled probe could make the trip ...

If you have been dreaming of traveling to another star system, researchers say you may need to use a sail. Penn Engineering and UCLA researchers show that light sails could provide interstellar ...

At the 2007 Laser Masters Worlds in Roses, Spain, International Laser Class president Tracy Usher started discussions about creating a new sail that would last longer than the existing sail, designed ...

Over the last two decades, Les Johnson and his team of engineers have quietly been pushing NASA into a new era of space exploration while nobody was paying attention. As an engineer at the legendary ...

Imagine a place like our solar system. A place with a ‘central’ star orbited by planets but light years away. There might be a planet there with water and living organisms. Now imagine if you could ...

The International Laser Class Association was established in 1972 to provide leadership for its membership, but that all ...
