SpaceX has released footage recorded on a rocket’s nosecone as it plummeted back to earth from space last month.
The company posted a video on Twitter, saying the neon-blue light is caused by friction heating up particles in the atmosphere during a high-speed descent.
This descent was particularly important for SpaceX.
It was the first time after a launch that the company has successfully recovered a piece of the rocket’s nosecone, which is also called a fairing.
The fairings split into two once a rocket enters space.
The pieces then fall back to earth and crash into the ocean.
This fairing-half guided itself into a giant net hoisted up by a crew boat.
It’s an important step toward SpaceX’s goal of re-using as much of its hardware as possible to drive down launch costs.
CEO Elon Musk has said SpaceX fairings cost about $6 Million.
