The Mil-Aero Command Post

Where great military and aerospace minds meet.

Dreaming of space ... and LEDs

Interesting e-mail today about communicating with the Space Station via light-emitting diode (LED) light bulbs.

As the International Space Station passed overhead in the night sky on 19 Sept., engineering students from the Schulich School of Engineering at the University of Calgary used their skills to communicate to astronaut Schulich graduate Bob Thirsk.


With the use of 1,200 donated LED lights from OSRAM Opto Semiconductors, 600 students gathered in a remote field and arranged the Opto LEDs into a message for Thirsk and the rest of the Space Station crew as they passed 186 miles above Calgary. The illuminated greeting spelled out DREAM.
