Phobos,
Is this the experiment where they use a special laser, firing a series of rapid pulses under a saucer-like shape, propelling it upwards? I remember the idea was to eventually design a model that could attain an orbital altitude. Could perhaps lead to sending payloads into orbit more cheaply than rockets.

The laser used for the first tests (with miniature spinning metallic models), was originally designed for the "Star Wars" defense project.
