Mission payload
STS-119 delivered the S6 solar arrays to the space station , completing the construction of the Integrated Truss Structure . [ 8 ] STS-119 also carried several experiments , including the Shuttle Ionospheric Modification with Pulsed Local EXhaust ( SIMPLEX ) , Shuttle Exhaust Ion Turbulence Experiments ( SEITE ) , and Maui Analysis of Upper Atmospheric Injections ( MAUI ) . STS-119 was also used for the `` Boundary Layer Transition Detailed Test Objective '' experiment . One tile of the thermal protection system was raised 0.25 inches ( 6.4 mm ) above the others so that , at about Mach 15 during reentry , a boundary layer transition would be initiated . [ 9 ] This experiment was repeated during STS-128 with the tile raised to 0.35 inches ( 8.9 mm ) , tripping at Mach 18 to produce more heat .
STS-119 (ISS assembly flight 15A) was a Space Shuttle mission to the International Space Station (ISS) which was flown by Template:OV-103 during March 2009. It delivered and assembled the fourth starboard Integrated Truss Segment (S6), and the fourth set of solar arrays and batteries to the station. The launch took place on 15 March 2009, at 19:43 EDT. Discovery successfully landed on 28 March 2009, at 15:13 pm EDT.
