NASA researchers have successfully tested laser communications in space by streaming 4K video footage originating from an airplane in the sky to the International Space Station and back.
The feat demonstrates that the space agency could provide live coverage of a Moon landing during the Artemis missions and bodes well for the development of optical communications that could connect humans to Mars and beyond. NASA normally uses radio waves to send data and talk between the surface to space but says that laser communications using infrared light can transmit data 10 to 100 times faster than radios.
