Starship: a Space Flight Company to Test a Rocket for the First Mars Orbit, and How to Refuel the Atmosphere
In South Texas, a commercial spaceflight company is preparing to test a rocket. The machine could one day carry humans to the moon, Mars and beyond.
Again, the decision to use such a large number of engines is a trade-off, according to Lozano. It allows the rocket to produce an enormous amount of thrust, which it needs to get off the ground. It’s actually difficult having that many rocket engines firing at the same time. I think that’s going to be one of the biggest challenges.”
“Eventually the Sun will expand and destroy all life,” Musk said, standing before the giant rocket about a year ago. “It is very important – essential in the long-term – that we become a multi-planet species.”
Musk hopes Starship will provide a critical step to becoming multiplanetary, by allowing large payloads to be carried into orbit for cheap. His goal is for Starship to someday transport the first people to Mars.
Development of Starship has been based at SpaceX’s privately held spaceport about 40 minutes outside Brownsville, Texas, on the US-Mexico border. Testing started with short “hop tests” of early prototypes. The company began with brief flights that lifted a few dozen feet off the ground before evolving to high-altitude flights, most of which resulted in dramatic explosions as the company attempted to land them upright.
Standing at nearly 400 feet tall, Starship is made of gleaming stainless steel, an unusual choice in a business where every pound of weight matters. Musk told the Space Studies Board of the National Academies that he started out looking at advanced, lightweight materials for Starship. But he quickly realized that steel was cheap, abundant, and most importantly, incredibly tough. It can tolerate the heat of re-entry better than other materials, and it can hold cryogenic rocket fuel.
Methane is an unconventional fuel choice for the rocket. H2O is lightweight and efficient, so it’s often used for fuel in high-powered rockets.
Methane is easier to produce and handles hydrogen more effectively, and it has trace amounts of methane in the atmosphere of Mars. It means a future mission to the red planet may be able to refuel by drawing methane from the atmosphere.
SpaceX is Getting Ready to Set Off Itself: A Spaceship to Launch the Most Powerful Aeronaut Ever Flyn to the Moon
To make up for its extra weight, Starship depends on powerful engines called Raptors. The spaceship uses six Raptors to fly, but the booster that will put it in space uses 33 of the same engines.
The Soviet Union tried to get to the moon at the end of the 1960s. It used 30 engines to launch the N1, which was the first stage. However, even a single engine failure was enough to cause the rocket to explode, and four prototypes were destroyed before the Soviets eventually abandoned the program. By contrast, America used five enormous engines for the first stage of the Saturn V rocket. The rocket could carry astronauts to the moon.
Musk thinks that the cheap,durable design of it will make it a workhorse for getting things into space. Speaking last year, Musk said he hopes the booster can be recycled six to eight hours per day.
In the near term, it won’t be carrying interplanetary missions. Instead, SpaceX needs it to transport satellites into orbit for its satellite-based Internet service known as Starlink. Users have been interested in Starlink, which is a major revenue-maker for the company. But the Starlink system is limited in how many subscribers it can support, says telecoms consultant Tim Farrar.
It would take many more satellites to build a system big enough to handle demand. Smaller rockets that are operated by the company can only be launched a few dozen at a time. The company can use bigger and more heavy satellites to increase profitability.
NASA is also paying SpaceX around a billion dollars to develop a version of Starship to visit the moon, though that mission is likely still several years away.
Just a few months after NASA introduced the world to the most powerful rocket ever flown to orbit, Elon Musk’s SpaceX is prepared to set off its own creation — which could pack nearly twice the power of anything flown before.
“I guess I’d like to just set expectations low,” SpaceX CEO Elon Musk said during a Twitter “Spaces” event for his subscribers Sunday evening. “If we get far enough away from launch pad before something goes wrong, then I think I would consider that to be a success. Just don’t blow the pad.
The inaugural flight test won’t complete a full circle around Earth. If successful, however, it will travel about 150 miles above Earth’s surface, well into altitudes deemed to be outer space.
Less than three minutes after takeoff, it’s expected to expend its fuel and separate from the Starship spacecraft, leaving the booster to be discarded in the ocean. The Starship will have its own engines that can run for more than six minutes.
The vehicle will then return to the Earth’s atmosphere near Hawaii. It’s expected to splash down off the coast about an hour and a half after liftoff.

The consequences of Starship’s ultimate success or failure are immense. Not only is it crucial to SpaceX’s future as a company — it also underpins the United States government’s ambitions for human exploration.
But it’s not all riding on this inaugural test flight. There have been mistakes and explosions in the name of refining the design of the spaceships created by Space Exploration Technologies.
In the lead-up to the first launch of the company’s Falcon Heavy rocket in 2018, which held the title of most powerful rocket before NASA’s SLS took flight last year, Musk foresaw only a 50-50 chance of success.
According to Musk, people from all around the world are coming to see what will either be a great rocket launch or the best fireworks display they have ever seen.
Since then, we have also been busy with preparation for the Super Heavy booster flight. The company’s Raptor engines are in the large, 230-foot-tall cylinder.
The company and federal regulators have faced opposition from the local community, including environmental groups, about the risks of certifying SpaceX launches.
The Federal Aviation Administration granted a request by the company to conduct an uncrewed test flight of the rocket out of South Texas.
The FAA has been looking at the compliance of SpaceX as the company prepares for the launch, according to an official who spoke with reporters last week.
NASA and SpaceX have been working for a year on a work flow. The two organization had to iron out in previous projects how to use each other and how to give each other a fair shake.
NASA is not, however, involved in planning the flight profile for this test flight or directing SpaceX on what to do, according to Lisa Hammond, NASA’s associate program manager of the Human Landing System at Johnson Space Center in Houston.
There will be a single uncrewed test flight on the Artemis II mission before humans get to ride on the SLS rocket, she said.
It’s not clear, however, if 2025 is feasible. The inspector general for NASA thinks it is not. The inspector general states that delays might be related to Starship.
NASA’s current timeline targets 2025 for the first lunar landing mission, which will see astronauts transfer from their Orion capsule, which will launch atop a NASA Space Launch System rocket, and into a Starship spacecraft already in lunar orbit. The crew will beferried down to the moon by the Starship vehicle.
