00:00:07,371 --> 00:00:10,239
in the Navy's second attempt to place a satellite into orbit.

In its nose, a grapefruit-sized metal sphere.

00:00:13,234 --> 00:00:17,445
The huge rocket, three stages of liquid fuel components, is actually

00:00:17,445 --> 00:00:21,518
still experimental. For Vanguard, every flight is a test flight!

00:00:32,350 --> 00:00:37,487
Takeoff is flawless. December 6th, Vanguard 1 lost thrust only four feet off the pad

00:00:55,250 --> 00:01:00,144
cameras record a pinwheel of fire. Another disaster for Project Vanguard!
