Update 2: Ares I-X launch video:

Update 1: NASA has issued the following press release regarding the launch or Ares I-X

Today at 15:30 UTC, NASA launched Ares I-X from launch pad 39-B at Kennedy Space Center in Florida. Ares I-X is the first test flight of the Ares I launch system – part of NASA’s Constellation program to developer spacecraft and booster vehicles to replace the Space Shuttle and send astronauts back to the Moon and possibly to Mars.

The first launch attempt yesterday was scrubbed due to weather rule violations and, at one moment, a cargo ship which ventured into the splash down and debris fallout area. The weather today was not much better at first, with what seemed to be a never-ending violation of the triboelectrification rule, but about 15:20 UTC, NASA launch weather officer, Kathy Winters, declared the weather green for the launch attempt at 15:30.

STS-128 is the first spaceflight for the shuttle pilot Kevin Ford, the flight engineer for launch and landing Jose Hernandez and the flight engineer for Expedition 20 and 21  Nicole Stott who will take the place of Astronaut Time Kopra aboard the station until her return home in November aboard STS-129.

The STS-128 mission will deliver to the station the Multi-Purpose Experiment Support Structure Carrier and the Multi-Purpose Logistics Module (Leonardo), whose main purpose is to assist with establishing a six-man crew capacity by providing extra supplies and equipment to the station, and the Lightweight Multi-Purpose Experiment Support Structure Carrier (LMC) with Ammonia Tank Assembly (ATA).

The Combined Operational Load Bearing External Resistance Treadmill, so named for comedian Stephen Colbert, will be transferred to the station on flight day 5 and set up after Discovery undocks from the station. Stephen Colbert himself, recorded a message for NASA (watch the video below)…

Every mission carries out Detailed Test Objectives (DTO’s). STS-128 has 5 planned DTO’s. One of them, the Boundary Transition Layer, will be the second phase of an experiment commenced on STS-119 in March this year.

Boundary Layer Transition is a process occurring during the shuttle re-entry as the smooth air flow along the shuttle’s heat shield becomes turbulent. The experiment will measure the heat difference between the air flow using sensors (thermometers) installed in particular tiles on the shield. A protuberance tile with a quarter inch (0.9cm) “speed bump” has been installed on Discovery’s heat shield. The tile will intentionally disrupt the smooth air flow and allow data gathering at Mach 18 during the re-entry.
