Lasers Could Send Missions to Mars in Only 45 Days - Universe Today universetoday
For this application, lasers are used to deliver power to photovoltaic arrays on a spacecraft, which is converted to electricity to power a Hall-Effect Thruster . This idea is similar to a system, where a laser array takes the place of a nuclear reactor. As Duplay explained, their concept is related but different:
“[A]rrays of fiber-optic lasers that act as a single optical element, inflatable space structures that can be used to focus the laser beam when it arrives at the spacecraft into the heating chamber, and the development of high-temperature materials that allow the spacecraft to break against the Martian atmosphere upon arrival.”

Lasers Recreate the Conditions Inside Galaxy Clusters - Universe TodayGalaxies don’t exist in a vacuum. Ok, maybe they do (mostly, since even interstellar space has some matter in it). But galaxies aren’t normally solitary objects. Multiple galaxies interacting gravitationally can form clusters. These clusters can interact with each other, forming superclusters. Our own galaxy is part of a group of galaxies called the Local … Continue reading 'Lasers Recreate the Conditions Inside Galaxy Clusters'
