Some examples of things that could qualify:

• Project Excalibur.

• The Jewish Space Laser.

• LISA.

Must be a big laser, intended to do something awesome. Someone bringing a laser pointer to the ISS doesn't count. Not does communications technology, that's old news. A ground-based laser also doesn't count, even if it's cool and has something to do with orbit. (If there's an orbiting mirror reflecting it somewhere though, that's awesome enough that I might make an exception.)
