The Boeing Delta 7326 (3:43) video

A model of the Boeing Delta 7326 is used by Boeing's Kris Walsh to describe the launch vehicle for the Genesis spacecraft. The Boeing Delta 7326 is a three-stage rocket. Kris describes each stage as it relates to the launch of the rocket.

TRANSCRIPTION of THE BOEING DELTA 7326 video:

We'll be flying the Genesis mission on a Delta 7326. And, this is the configuration right here. Genesis is a smaller payload so we only have three solids which are all ground-lit, and we'll have the nine and a half-foot fairing again for a smaller vehicle. At liftoff, all three solids will be lit. In addition, our main engine, which is a liquid engine -- we have fuel of kerosene and liquid oxygen -- they will all be firing at the same time. The ground-lit graphite-epoxy motors burn for approximately 66 seconds and then they will be separated from the vehicle. The main engine fires for approximately four minutes. Then we go through what we call a main engine cut-off, and the main engine will shut down. We'll separate and we will then be flying with another liquid stage, the Aero Jet I-Tip second stage. And just a few seconds later, the fairing will separate. So we'll just have the second stage, the third stage which is the Thiokol Star 37 [Solid Rocket] motor and the Genesis satellite. The second stage has the capability of numerous restarts and cutoffs. We'll get into the proper orientation. Then we will start spinning the third stage. Once the third stage fires, you can't shut it down. It'll continue firing until it burns out. Then we will continue to coast until the satellite's in the proper orbit and then we'll separate the satellite.
