BOCA CHICA VILLAGE, Texas — As Elon Musk, the founder and chief government of SpaceX, says repeatedly, he created a rocket firm as a result of he needed to colonize Mars. His fervent argument is that humanity should unfold to a second planet as insurance coverage for long-term survival.

On Saturday, Mr. Musk will give a progress report on Starship, an enormous rocket that’s the centerpiece of these ambitions, at SpaceX’s launch website close to the southern tip of Texas.

The replace is anticipated to start at eight p.m. Eastern time. You can watch it at SpaceX’s website.

Starship is the most recent identify for the higher stage of what Mr. Musk had been calling B.F.R. The “B” stood for Big, the “R” stood for Rocket, and Mr. Musk by no means publicly acknowledged the which means of “F.”

SpaceX at present flies two rockets: the Falcon 9 and the Falcon Heavy, which is basically a Falcon 9 with two further Falcon 9 boosters connected to the aspect. The present-day Falcons are too small for sending individuals to Mars.

Mr. Musk and SpaceX have lengthy envisioned a a lot bigger rocket. For some time, Mr. Musk referred to it because the “Mars Colonial Transporter.” But when he finally revealed a design on the International Astronautical Congress in Guadalajara, Mexico, in 2016, he known as it the “Interplanetary Transport System.”

This spaceship was gargantuan, with a diameter of almost 40 toes, and the capability to take 100 individuals to Mars.

A yr later in Australia, Mr. Musk mentioned the rocket had been scaled down by one-quarter, to a diameter of 30 toes. This was the B.F.R. The second stage was sleek-looking spacecraft that will return to Earth in a single piece, and land vertically.

Last November, SpaceX introduced the Starship identify; the primary stage of B.F.R. is now generally known as the Super Heavy booster. In current days, Mr. Musk has been posting updates because the prototypes come collectively.

Starship with the Super Heavy booster is basically a rocket as highly effective as a Saturn 5, which took NASA’s Apollo astronauts to the moon 50 years in the past, however it’s totally reusable. For Apollo, every part however the small capsule on high, the place the astronauts sat, was discarded alongside the way in which, and even the capsule may solely be used as soon as.

Experts say Starship is throughout the realm of the potential, with out requiring not possible physics or unlikely technological leaps. Indeed, Starship employs concepts that had been studied a long time in the past however by no means constructed. The largest innovation is maybe that SpaceX and Mr. Musk have utilized the accelerated research-and-development strategy of Silicon Valley, constructing quick and fixing failures quick.

Two competing groups at SpaceX are each building prototypes of Starship. One is in Florida, close to Cape Canaveral; the opposite is at Boca Chica in Texas.

While most rockets as of late have extra utilitarian appearances, SpaceX’s prototype resembles one thing from an outdated sci-fi film of the 1950s.

In half, that’s as a result of in its rush to get the prototypes to the launchpad, SpaceX has not bothered with such aesthetic niceties as paint. But there are also good engineering causes for the selection of fabric.

Mr. Musk initially had deliberate to use high-tech carbon fiber, however switched to stainless-steel. Steel is heavier than carbon fiber and aluminum, one other frequent materials used for rockets, however it’s also cheaper and has the next melting temperature that may extra simply stand up to the warmth of re-entry into Earth’s environment.

In August, SpaceX examined a easy prototype that it known as Starhopper, with a single engine, which Mr. Musk earlier compared to a flying water tower. It lifted to an altitude of 500 toes, flew sideways after which set down at a distinct spot.

The flight lasted 57 seconds. A shorter July flight went 65 toes within the air.

At Saturday’s presentation, Mr. Musk is probably going to present up to date schedules for the following part of take a look at launches, which is able to begin with suborbital flights earlier than heading to orbit. SpaceX officers have mentioned {that a} cargo model of Starship may begin launching satellites as early as 2021.

A Japanese billionaire, Yusaku Maezawa, has bought an around-the-moon journey on a Starship that’s to take off in 2023.

Mr. Musk, nevertheless, has a historical past of overly optimistic predictions. In Guadalajara in 2016, for instance, he mentioned the goal was to ship the primary cargo flight to Mars in 2022 and the primary individuals there two years later. Those dates are unlikely to be met.

On Friday, NASA Administrator Jim Bridenstine reminded Mr. Musk that NASA, SpaceX’s largest and most necessary buyer, was awaiting the supply of one other huge SpaceX challenge: taking NASA astronauts to the International Space Station within the firm’s Crew Dragon capsules.

Neither SpaceX nor Boeing, which additionally acquired a contract for offering transportation for NASA astronauts, seems to be on monitor to launch crews this yr. When the contracts had been awarded in 2014, NASA hoped that the flights would start as early as 2017.

While specialists discover Starship to be technologically possible, they do query how SpaceX could make sufficient cash with it. Without a worthwhile enterprise, SpaceX couldn’t finance its costly Mars ambitions, that are unlikely to become profitable anytime quickly.

Mr. Musk has talked of the Starship changing each Falcon 9 and Falcon Heavy. But the rocket is way larger than wanted: Think of taking a semitrailer truck to go grocery buying.

A cargo Starship may conceivably take up a number of satellites without delay, however satellites sometimes circle Earth in numerous orbits, and coordinating launches amongst completely different prospects is tough.

SpaceX officers have additionally talked about how Starship may shuttle individuals internationally at speeds a lot sooner than airplanes; a flight from New York to Tokyo may take lower than an hour. Still, the query stays: How many individuals are keen to pay at nice expense for a sooner journey?

NASA is working by itself huge rocket, known as the Space Launch System, that can initially have the opportunity to carry about 70 metric tons; a later, upgraded model is to carry 130 metric tons. (Starship with Super Heavy will carry greater than 100 metric tons.)

But whereas SpaceX’s Starship and Super Heavy make the most of cutting-edge applied sciences and are totally reusable, S.L.S. is basically a remix of elements from the retired house shuttles.

It can also be not reusable; estimates are that it’ll price $1 billion per launch, and launch not more than every year.

NASA additionally already spent billions on S.L.S., first introduced in 2011, and Orion, the crew-carrying capsule. The first S.L.S. flight has been delayed for years; it isn’t anticipated to carry off till 2021. The first moon touchdown by astronauts is to happen on the third launch of S.L.S.

The delays and value overruns of S.L.S. frustrate many house aficionados, in addition to NASA’s inspector common and the United States Government Accountability Office. Some contend NASA may get locations faster and extra cheaply if it took higher benefit of business developments like Starship.

However, to date, Congress, which decides NASA’s finances and priorities, has continued to finance work on S.L.S. and Orion.
