Image 1 of 50 (Image credit: SpaceX) Starship and Super Heavy Elon Musk founded SpaceX in 2002 primarily to help humanity settle Mars. Here's a look at the gear the company is developing to do just that — a giant rocket called Super Heavy and a 100-passenger vehicle called Starship. Above, a still from a SpaceX animation shows Starship launching on a Super Heavy rocket. Video: See SpaceX Starship Launch in New Animation

Image 2 of 50 (Image credit: Elon Musk/SpaceX) "BFR" in 2018 Starship and Super Heavy have gone by several names. When first unveiled in 2017, the duo was known as the Interplanetary Transport System. A year later, Musk changed the name to BFR, short for "Big Falcon Rocket" (or "Big F***ing Rocket). In November 2018, it was renamed again to "Starship."

Image 9 of 50 (Image credit: SpaceX) In-Orbit Refueling One of the key elements of SpaceX's Starship plan is the ability to refuel the spacecraft in orbit. After launching, Starship will rendezvous with a tanker in orbit and refuel before heading out to Mars or other deep-space destinations. You can see how it's done in this SpaceX animation.

Image 30 of 50 (Image credit: SpaceX) Starship and Super Heavy Ascent Before it was Starship, it was called the BFR, or "Big Falcon Rocket." SpaceX's 2018 BFR design showcased a sleek, sci-fi looking spaceship and its 1st stage booster as shown in this image unveiled by Elon Musk on Sept. 17, 2018.

Image 31 of 50 (Image credit: SpaceX) At the Moon On Sept. 13, 2018, SpaceX announced it had signed the 1st private passenger for a moon trip on BFR. This image released with that announcement offered the first glimpse of BFR's design changes since the 2017 ITS version (which fill much of this gallery).

Image 42 of 50 (Image credit: SpaceX) A Big Rocket SpaceX's envisioned BFR is much bigger and far more powerful than the company’s other rockets.

Image 43 of 50 (Image credit: SpaceX) Big BFR The BFR iteration was designed to be 387 feet (118 meters) tall, with the ability to carry payloads up to 100 metric tons all the way to the surface of Mars.

Image 44 of 50 (Image credit: SpaceX) A Spacious Spaceship The BFR's design was more spacious inside, fitting more than 35,000 cubic feet (1,000 cubic meters) of pressurized space inside. The payload section measured 180 feet (55 meters) long. That's more than 10 times the size of the space shuttle's living quarters.

Image 45 of 50 (Image credit: SpaceX) Steering the BFR The 2018 BFR design had two actuated forward fins and three in the rear. (Elon Musk also referred to these features as "wings" or "fins.")
