Launch Abort System Installed for Orion Flight Test

NASA – The launch abort system for the Orion Flight Test is lowered by crane for installation on the Orion spacecraft inside the Launch Abort System Facility, or LASF, at NASA’s Kennedy Space Center in Florida. The completed crew and service modules will be tested and verified together with the launch abort system. Orion will remain inside the LASF until mid-November, when the United Launch Alliance Delta IV Heavy rocket is ready for integration with the spacecraft.

Orion is the exploration spacecraft designed to carry astronauts to destinations not yet explored by humans, including an asteroid and Mars.

It will have emergency abort capability, sustain the crew during space travel and provide safe re-entry from deep space return velocities.

The first unpiloted test flight of the Orion is scheduled to launch in December atop the Delta IV Heavy rocket from Cape Canaveral Air Force Station in Florida to an altitude of 3,600 miles above the Earth’s surface. The two-orbit, four-hour flight test will help engineers evaluate the systems critical to crew safety including the heat shield, parachute system and launch abort system.

Rocket Boosters Prepared For Orion Spacecraft’s First Flight

NASA – Engineers took another step forward in preparations for the first test flight of NASA’s new Orion spacecraft in December. At the United Launch Alliance (ULA) Horizontal Integration Facility (HIF), at Cape Canaveral Air Force Station, Florida, the three primary core elements of the ULA Delta IV Heavy rocket recently were integrated, forming the first stage of the launch vehicle that will send Orion far from Earth to allow NASA to evaluate the spacecraft’s performance in space.

The three common booster cores are 134 feet in length and 17 feet in diameter. Each has an RS-68 engine that uses liquid hydrogen and liquid oxygen propellant producing 656,000 pounds of thrust. All totaled, the three Delta IV boosters collectively generate 1.96 million pounds of thrust.

The upcoming flight test will use the Delta IV Heavy to launch the Orion and send it 3,600 miles in altitude beyond the Earth’s surface. During the two-orbit, four-hour mission, engineers will evaluate the systems critical to crew safety, the launch abort system, the heat shield and the parachute system. The data gathered during the mission will influence design decisions and validate existing computer models. The flight also will reduce overall mission risks and costs for later Orion flights.
