J2X Engine Test Concepts

NASA conducted a critical test of the J2X engine at the Stennis Space Center in Mississippi. The test aimed to fire the engine for 500 seconds, twice as long as previous tests, to ensure it can safely maneuver outside Earth's orbit. The engine successfully fired for the required duration, demonstrating its capability to generate 290,000 pounds of thrust and burn a large amount of fuel. The test, costing $350,000, was crucial for ensuring astronaut safety in deep space missions. Observers noted the intense vibrations and noise produced by the engine, which could be felt miles away.

What is the primary purpose of the J2X power pack test?

• To determine the fuel efficiency of the engine

• To measure the noise level of the engine

• To calculate the cost of space missions

• To test the engine's ability to fire for 500 seconds

Why is the test considered expensive?
