SailDrone makes wind powered + solar powered ocean drones to understand planetary systems affecting humanity. The company designs, manufactures, and operates their global fleet sail-drones — monitoring the state of the planet in real time. Their data sets can be used by commercial enterprise, research institutions, or private groups on specific missions.
SailDrone is making world history by offering high resolution, ocean data collection at-scale. Their sail-drone is 20 feet long, 18 feet high above the water, weighs 600 pounds. It can operate indefinitely: the wind is propulsion that pushes it along, a solar power panel charges the batteries that run the on-board computers + communications equipment.

Aiming a laser beam at an aircraft isn’t a harmless prank: The sudden flash of bright light can incapacitate the pilot, risking the lives of passengers and crew. But because attacks can happen with different colored lasers, such as red, green or even blue, scientists have had a difficult time developing a single method to impede all wavelengths of laser light. Today, researchers report liquid crystals that could someday be incorporated into aircraft windshields to block any color of bright, focused light.

The Event Horizon Telescope (EHT), a network of eight radio observatories spanning the globe, has set its sights on a pair of behemoths: Sagittarius A*, the supermassive black hole at the Milky Way’s center, and an even more massive black hole 53.5 million light-years away in galaxy M87. In April 2017, the observatories teamed up to observe the black holes’ event horizons, the boundary beyond which gravity is so extreme that even light can’t escape. After almost two years of rendering the data, scientists are gearing up to release the first images in April, 2019.
