Tomorrow is a big day for Elon Musk: his company SpaceX will be launching the new Falcon Heavy rocket from NASA’s Kennedy Space Center in Cape Canaveral, Florida, seven years after the vehicle was first announced. It will be a demonstration mission, meant to test if the rocket can send a payload into orbit. And that payload will be Musk’s red Tesla Roadster... driven by a dummy, perhaps.

Musk, being the teasing entrepreneur that he is, just posted three photos to Instagram showing that very Roadster with a noteworthy passenger behind the wheel: a dummy wearing the new SpaceX space suit. The images show the dummy sitting in the car that’s mounted on a dome structure with what looks like cameras attached to the front section.

Some eagle-eyed Reddit users have also spotted a very meta and very small figurine of the astronaut in the red Roadster on the dashboard of the vehicle.

It’s not clear if the dummy is actually going up inside the car on Tuesday, but seeing as how SpaceX is launching a car in the first place, anything seems possible. Musk initially teased photos of those space suits last year. They’re designed for people traveling inside the Crew Dragon, a vehicle SpaceX is building to transport NASA astronauts to and from the International Space Station. If the spacecraft experiences sudden depressurizing, the suits will keep the astronauts alive until they’re able to reach safety.
