Testing in Arc-heated wind tunnel
We have made significant progress in the development of source particles and have already succeeded in attaining enough brightness to be seen in a city sky under laboratory settings.
An arc-heated wind tunnel is a device that simulates an object entering the atmosphere. Under vacuum, the source particle is subjected to high-pressure, high-energy jet injection, simulating the conditions upon entering the atmosphere. Its brightness is measured as it burns against friction with the atmosphere. We have successfully measured apparent brightness of -0.86 in an experiment performed in winter of 2014.
