Could US Navy's Railgun Help Tap Moon's Resources?

Recent testing of the electromagnetic railgun under Navy auspices had the technology firing a projectile that exceeds Mach 6, approaching a velocity that hearkens back to early ideas of utilizing this machinery on the moon to hurl payloads from the lunar surface.

Mach 6 — six times the speed of sound — is about 4,600 mph (7,400 km/h) at sea level here on Earth. The escape velocity from the relatively small, nearly airless moon is about 5,300 mph (8,530 km/h).

Webmaster's Commentary: 

The trick will be to build a container able to survive the impulse of the railgun, with an onboard rocket to circularize the trajectory into an orbit.
