Quick look: NASA Orion’s critical test mission

NASA will this week launch Orion, which is destined to fly humans to the moon, asteroids and Mars.

The mission

Orion is the first spacecraft built for astronauts destined for deep space since the Apollo missions and ultimately it is destined for deep space travel -- but this week the spaceship went out for a short jaunt outside Earth. NASA says Orion’s unmanned test flight – slated for launch Thursday, is intended to test many of the riskiest elements of leaving Earth and returning home in the spacecraft including the jettison of the launch abort system; the separation of the Orion crew module from its service module ahead of its reentry though Earth’s atmosphere; the heat shield, which will experience temperatures near 4,000 degrees Fahrenheit and how Orion’s computers handle the radiation from the Van Allen Belt.

The capsule

The Orion capsule is moved at Kennedy Space Center in Florida Nov. 11, 2014. The NASA spacecraft designed to one day fly astronauts to Mars rolled out of its processing hangar at the U.S. space agency's Kennedy Space Center in Florida to be prepared for a December test flight.

The rocket

The Orion spacecraft is seen atop a United Launch Alliance Delta IV Heavy rocket at Kennedy Space Center, Fla. Orion will travel 3,600 miles (5,794 kms) in altitude above Earth. The spacecraft will re-enter the atmosphere 4 1/2 hours later at 20,000 mph (32,187 kph) and splash down in the Pacific Ocean, according to NASA.

New safety system

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.

Heat hot

Technicians work on the heat shield of NASA's Orion space capsule at Kennedy Space Center. Measuring 16.5 feet in diameter, the heat shield is made from a single seamless piece of Avcoat ablator.

Watching the event

A new countdown display has been constructed in the place of the former analog countdown clock at the Press Site at NASA's Kennedy Space Center in Florida. The display is a modern, digital LED display akin to stadium monitors. It allows television images to be shown along with numbers.

Paying tribute

An oxygen hose like those used by space-suited Apollo astronauts will soar into space aboard Orion during the first flight test. Orion also holding a tiny sample of lunar soil that will be used to inspire students toward science and engineering fields. A prehistoric fossil from a Tyrannosaurus Rex from the Denver Science Museum will make the flight as a reminder of how much life the Earth has seen during its existence. And a microchip with the names of more than a million people who submitted their names to be part of NASA’s exploration efforts will make the trip, as well.
