US: College football team given 120 lasers to "make a point"

In a motivational tactic, 120 University of Houston football players were each given a laser pointer during a team meeting during the last week of October 2015. The lights went out, and Carl Lewis Auditorium was filled with 120 red lights, each pointed in a different direction. The coach, Tom Herman, then told the players to focus on a sign at the front of the room.

Herman was later quoted as saying “When you can see all these lasers everywhere, it just kind of represents everything that goes on in the lives of 18- to 22-year olds. We needed everybody to shut all that out and bring all that into one common focus.”

The tactic may have helped; the Houston Cougars went on to beat the Vanderbilt Commodores 34-0 on October 31 2015.

US: Amateur astronomers illuminate International Space Station with spotlights and 1-watt laser

On March 4, 2012, amateur astronomers from San Antonio and Austin were able to flash the International Space Station with two 800 million lumen white spotlights and a 1-watt blue laser, aimed from the Lozano Observatory in Spring Branch, Texas. This appears to be the first time that astronauts have seen civilian light beams aimed at them.

The spotlights were flashed at the ISS by holding plywood sheets in front of the lights every two seconds. This procedure can be seen in the video below.

The animated GIF above shows a bright blue light alternating with a dim light. The bright light is almost certainly from the spotlights. The bluish tint may be an artifact of oversaturating the camera’s sensor. Astronaut Don Pettit reported that the bright light appeared white, and the dim light appeared blue. He wrote “We could only see the laser when the white light was off and not all the time.” (E.g., the white spotlights overpowered the blue laser.) He added, “It was like there were tracking issues with the laser to keep it on target.”

The dim light in the animated GIF may be the laser only, or it may be light from the spotlights that wasn’t fully blocked by the plywood sheets. The astronomers will be working with Pettit, trying to pin down exactly how visible the laser light was.
