Lockheed Martin team tests Orionís protective panels

LM-Orion1
Testing at the Lockheed Martin Sunnyvale facility in California using a series of precisely-timed, explosive charges and mechanisms, proved the Orion spacecraft can successfully jettison its protective fairing panels.

The Orion spacecraft has three fairings that protect the service module radiators and solar arrays from heat, wind and acoustics during ascent. This test was the second in a series of fairing separation testsóthis time adding a thermal element. Engineers used strip heaters to heat one of the fairings to 200 degrees Fahrenheit, simulating the temperature the spacecraft will experience during its climb to orbit.

The testing revealed there was a successful separation of all three fairings while under flight-like thermal and structural conditions. The separation velocity and trajectory of each panel were within the Lockheed Martin predicted tolerances. The test data provides a high level of confidence that the panels will jettison as expected during the launch vehicle ascent.

This successful test provides the Orion team with the needed data to certify this new fairing design for Exploration Flight Test-1 (EFT-1) next year. The test also provides significant risk reduction for the fairing separation on future Orion manned missions, said Lance Lininger, engineering lead for Lockheed Martinís Orion mechanism systems.

Unique to Orion, the spacecraftís fairings support half the weight of the crew module and the launch abort system during launch and ascent. This is a new design that improves performance, saves mass, and maximizes the size and capability of the spacecraft.

The Orion Multi-Purpose Crew Vehicle is NASAís first spacecraft designed for long-duration, human-rated, deep space exploration. Orion will transport humans to interplanetary destinations beyond low Earth orbit, such as asteroids, the moon and eventually Mars, and return them safely back to Earth.

Lockheed Martin is the prime contractor to NASA for Orion, and is responsible for the design, build, testing, launch processing and mission operations of the spacecraft.

In September 2014, Orion will complete its first high orbital mission. EFT-1 will launch an uncrewed spacecraft from NASAís Kennedy Space Center 3,600 miles beyond low Earth orbit. On the same day, Orion will return to Earth at a speed of approximately 20,000 mph for a splashdown in the Pacific Ocean. EFT-1 will provide engineers with critical data about Orionís heat shield, flight systems and capabilities to validate designs of the spacecraft before it begins carrying humans to new destinations in the solar system.
