Earlier this month, SpaceX’s Falcon Heavy emerged out of earth’s atmosphere and delivered a cherry red Tesla Roadster into space. The launch was televised, photographed, and, for a few hours at least, live streamed from a camera mounted on the hood of the car, which as of February 16 was tumbling through space at speeds upwards of 75,000 mph.
But despite the mass coverage, one man wanted a different kind of shot of the Roadster.
“...once footage of the car and Starman started to arrive and people wondered if it could be observed from Earth, there was just one thing in my mind: to find the answer to that question and if yes, to try take a picture – better yet, a video – of it,” wrote astrophotographer Rogelio Bernal Andreo on his blog Deep Sky Colors.
Two days after the launch, Andreo started tracking down the Roadster’s ephemeris, which is basically an astronomical itinerary that gives the precise locations of space objects over time.
Andreo mapped out the ephemeris on a software application he uses to control his telescope rig, which consists of three telescopes, electronic equipment, two cameras, and an ultra-sensitive mount that’s able to move the rig with “hair-thin precision.”
Late on the night of February 9, Andreo set up his rig in a field outside of his hometown of Sunnyvale, California in an attempt to photograph the Roadster, which then was about 500,000 miles away from earth. But by 5:15 a.m. he had seen nothing. He packed and left.
After a nap, he checked his data again. Still nothing. Then he realized he had made a mistake – after all, amateur astrophotography might not be rocket science, but it’s still pretty complicated.
“Then it hit me!! When I created the ephemeris from the JPL's website, I did not enter my coordinates!! I went with the default, whatever that might be! Since the Roadster is still fairly close to us, parallax is significant, meaning, different locations on Earth will see Starman at slightly different coordinates. I quickly recalculate, get the new coordinates, go to my images and thanks to the wide field captured by my telescopes... boom!! There it was!! Impossible to miss!! It had been right there all along, I just never noticed!”
Here’s the raw footage of what he captured.
And a polished version.
Andreo wrote that astrophotography has many different applications.
“I utilize technology that allows me to capture ancient photons so that I can later process and create my own interpretation of the data captured, effectively blending art and science like not many other disciplines do, but I don't usually track "small pixels in space" (aka comets, asteroids and yes, even spacecraft) as some of my peers do. Yet, surely enough, comes the day when someone decides to launch a cool red car "driven" by a dummy in an astronaut costume, I had but to go for it! Yeah, red sports cars make even tiny pixels look cool!”
