There are many wonderful places we’d like to visit in the universe, and probably untold numbers more that we haven’t even seen or heard of yet. Unfortunately…they’re all so darn far away. A ...

A new study suggests laser-driven interstellar lightsails may face a hidden efficiency problem as the very light pushing them ...

Adapting the concept of interstellar laser sailing for Earth orbital maneuvering and solar system exploration, researchers propose that the fundamental advantages of laser propulsion are manifested at ...

Spacecraft could fly to distant stars using sails with surfaces similar to those of CDs and DVDs to help them stay centered on laser beams, a new study finds. Conventional rockets driven by chemical ...

But wait! Is that the rumble of revolution I hear growing louder with each passing sailing day? Why are there so many Laser sailors out there on the water with crisp, new sails that—gasp!—aren’t made ...

It is feasible but very difficult to make a laser pushed sail reach 20% of the speed of light. The general parameters are for an array of lasers with 100 Gigawatts of power to push a 1 gram solar sail ...

Talia Hamlin has specific goals this week as she competes in her first ILCA (International Laser Class Association) North American Championship. She wants good starts, to sail through the waves with ...
