Six hours after SpaceX launched its new Falcon Heavy rocket on its first test flight yesterday (Feb. 6), unsuspecting skywatchers in the western U.S. caught a glimpse of the rocket's second stage firing up one last time as it blasted out of Earth's orbit and off into the solar system.
Riding on the rocket's second stage was Elon Musk's Tesla Roadster, an electric vehicle with a dummy named "Starman" behind the wheel. After the launch, the car and its passenger spent nearly 6 hours orbiting the Earth on the rocket's second stage, or the upper portion of the rocket that is designed to deliver payloads into orbit.

At about 9:45 p.m. EST (0245 GMT), the rocket performed its third and final burn, which was supposed to send this dummy payload cruising by Mars in an elliptical orbit around the sun. (However, the rocket overshot its target and ended up on a path toward the asteroid belt instead.)
Shortly after the second stage initiated this burn, people in the western U.S. began reporting rocket sightings in the evening sky. While SpaceX has not officially confirmed that the images or videos on social media were of the Falcon Heavy, it was the only rocket scheduled to be flying over the Earth at that time and place, so it seems highly unlikely these spectators saw anything else.

While many of the witnesses reported seeing the rocket by chance when they just happened to look up, at least one telescope — the MMT Observatory (MMTO) in Mount Hopkins, Arizona — spotted the Falcon Heavy during routine night-sky observations.
"The big, fast-moving blob is the exhaust from the Falcon Heavy's burn," Timothy Pickering, a staff scientist at MMTO, said in a tweet. "There's also a plane heading north at the beginning and a small satellite at the end."
Another Twitter user, Brittany Brelle, shared a photo of the rocket taken from Southern California, tweeting, "Moral of the story: Always look up and follow the moving thing in the sky."
