With the rocket engine tied to the earth, where does all that thrust go? |

Based on the engine's orientation with regards to the Sun, appears the impulse is added to the Earth's spin precession.  |

I think that is Scott's way of saying the thrust is reacted into the hold down fixture that is inturn reacted into the earth. |

NASA TV will carry the test live on its television channel and streamed through its website. |

Has there or will there be any "special" commemoratives offered to celebrate the test such as artifacts, rocket glass, or first day covers? |

Since SLS will fly only once a year, its SRBs would not be collected, refurbished and reused. Is this to keep costs down as it would be cheaper to build a whole new SRB, than to pay the costs of collection and refurbishments for re-use? |

The driving factor was cost savings, yes. Orbital ATK has a sufficient supply of case parts left over from the shuttle to support SLS until an advanced booster is adopted. |
