NASA in 2017 will run test flights of its new Space Launch System, which uses rocket motors made by defense and aerospace contractor Alliant Techsystems. The move is positive news for ATK, which previously made motors for the now-shelved space shuttles. "We are absolutely on schedule and have our next ground test for the five-segment booster scheduled for next summer. And just three weeks ago we completed a major avionics test for the system," said George Torres of ATK.
