The US space agency
has spent a long, long time designing, developing, building, and testing the Space Launch System rocket.
When NASA created the
rocket program in 2010, US legislators said the SLS booster should be ready to launch in 2016.
NASA and its litany of
contractors are very close to declaring the 111-meter tall rocket ready for its debut launch.
On June 20, NASA
successfully counted the rocket down to T-29 seconds during a pre-launch fueling test.
Although they did not reach
T-9 seconds, as was the original goal, the agency's engineers collected enough data to satisfy the requisite information
During a pair of news
conferences last week, NASA officials declined to set a launch target for the mission.
In Tuesday interview
Jim Free, said the agency is working toward a launch window of August 23 to September 6.
