In September 2019, Elon Musk unveiled the first iteration of his next-generation vehicle Starship.

SpaceX continues to push the limits and this next endeavour may be its most ambitious yet.

The company was founded with the intention of one day creating a human colony on Mars,

and Elon Musk hopes that Starship and the Super Heavy rocket will be the way to get

First things first, let’s clear up the names. Over the years, the transportation system

has had multiple name changes starting with Interplanetary Transport System to BFR a.k.a.

Big Falcon Rocket, although allegedly Elon uses the "F" in a very different way, and finally, Starship.

Built to carry 100 passengers, Starship will

serve as the spacecraft to shuttle both people and cargo to Earth’s orbit and beyond.

At 50 meters, Starship was initially supposed to be built with carbon fiber, but in January

2019, the team made the switch to stainless steel. The material is denser and has greater

thermal properties allowing it to better withstand the heat during re-entry. It’s also cheaper,

and of course, it looks awesome. The spacecraft is powered by six Raptor engines,

three for its time in the atmosphere, and the rest for propulsion in space. Each Raptor

engine is fueled with cryogenic methane and liquid oxygen.

While Starship has its six raptors, the real

power behind this transportation system comes from the Super Heavy rocket. Standing at 68

meters high and with 72 meganewtons of thrust at liftoff, the Super Heavy can carry more

than 100 metric tons. That’s because this rocket has thirty-seven Raptor engines.

In its final iteration, the combined Starship and Super Heavy will be the world’s most

powerful launch vehicle ever developed. Once it reaches Earth’s orbit, the booster and

spacecraft will detach. Starship will continue on its way to its destination, while Super

Heavy will return to Earth, landing vertically like previous Falcons. As for Starship, when

it returns from its galactic voyages, this behemoth of a spacecraft will re-orientate

itself and re-enter the upper atmosphere at around at a 60-degree angle. Then, as it nears

just a few hundred meters from the ground, the ship will turn its engines on to adjust

itself for a swift vertical landing. Needless to say, this will make for a nail-biting,

And SpaceX is working fast to bring this project to life. In the spirit of healthy intra-company

competition, the company is building multiple Starship prototypes at different locations:

The Mark 1 in Boca Chica, Texas and Mark 2 in Cape Canaveral, Florida. Other versions

are planned, however the lucky version that will fly,  will most likely be a later iteration

At this point, you may be wondering, how on Earth is SpaceX going to pay for all this?

Well, by building one ship and one booster, SpaceX envisions that this system will allow

it to pool its resources to focus on just one fully reusable system instead funding

multiple like the Falcon 9, Falcon Heavy, and Dragon capsule. Starship would continue

to run re-supply missions to the ISS, with the added bonus of being able to shuttle both

crewmembers and cargo at a relatively lower cost than the Falcon vehicles.

SpaceX would continue to launch satellites, and thanks to Starship’s massive 9m diameter

forward payload section, it would be capable of delivering payloads even larger than the

James Webb Space Telescope into Earth’s orbit. Finally, there’s also the lofty idea

of using Starship as a new, high speed way of commercial travel, transforming the 14

hour plane ride from New York to Tokyo to just under an hour.

But it might be awhile before we take those types of flights. As for the final Starship,

Musk envisions its uncrewed orbital test flight could happen by spring of 2020. So until then,

it seems that Musk may be one step closer to his vision of getting humans to the red
