Page "STS-34" Paragraph 20

The mission's primary task was to deploy the Galileo spacecraft with its attached IUS booster.

Deployment occurred on schedule at 19: 15 EDT on 18 October, slightly more than six hours after launch, and the IUS successfully boosted Galileo toward Venus on the first leg of its six-year journey to Jupiter.

The spacecraft was injected on a Venus transfer orbit at 20: 20 EDT, and separated from the IUS 47 minutes later.
