Starship mikt op minder dan 270 dollar per kg.

Kortom,bijna 100 keer minder.

Wat Space X gaat vragen per ton kan vanaf $100.000 zijn of vanaf $ 100 per kg, toch volgens deze link.

Operationele kost is ~$ 2 miljoen voor 100 ton, of ~$ 20 per kg...

SpaceX’s Starship could sport a low cost per rocket flight — somewhere in the region of $2 million.

During a fireside chat at the Los Angeles Air Force Base, CEO Elon Musk told Lieutenant General John Thompson, commander of the U.S. Air Force Space and Missile Systems Center, that “we consider our operational costs would probably be around $2 million per flight.” That includes a cost of fuel and oxygen at around $900,000.

It’s an impressively low price, particularly considering the cost per kilogram to normally fly cargo into space. SpaceX’s ultimate goals are aimed at reducing the cost of rocket launches, making them more commonplace, and using that to fund its goals of building bases on the moon, Mars and beyond. While its low costs would likely help reach the first goal, its use of liquid oxygen and methane as fuel means astronauts could conceivably embark on those more ambitious missions and refuel at the planet.

The Starship is designed to transport at least 100 metric tons to Earth orbit. Musk compared it to the Boeing 747, which has a similar payload capacity of over 100 tons, which costs $500,000 to lease for a flight from San Francisco to Sydney and back. Although the rocket is going into space, it would only cost around four times more in terms of operation. Musk attributed this discrepancy, especially considering the cost of previous space technology, to SpaceX’s focus on creating reusable rockets.

“A giant reusable craft costs much less than a small, expendable craft,” Musk said.

SPACEX STARSHIP: HOW IT COMPARES TO CURRENT ROCKETS

The $2 million operational costs are a far cry from the amount SpaceX charges for its current launches, using its semi-reusable series of Falcon vehicles.

For its Falcon 9 rocket, SpaceX charges $62 million to send up 5.5 tons to geosynchronous transfer orbit. For the Falcon Heavy, SpaceX charges $90 million to send up eight tons to geosynchronous transfer orbit. Both of these result in a price of $11.3 million per ton.

Note that these are the final prices offered to buyers rather than the operational costs. When Business Insider asked SpaceX to reveal the profit margins on its Falcon launches, the company refused to answer. However, an April 2016 analysis by investment firm Jefferies International estimated the gross margins at around 40 percent.

That would mean SpaceX pays around $6.8 million for each ton it moves into geostationary transfer orbit using a Falcon vehicle. A Starship, based on Musk’s figures, would cost around $20,000 per ton. Musk didn’t specify what sort of flight this would cover, though — in August 2019, he suggested the cost of sending one ton of cargo to Mars could be around $100,000 at the low end. That would mean his ambitions of building a city with one million tons of cargo would cost $100 billion, although suggested the figure could be as high as $10 trillion.

A fully-reusable Starship, offering much cheaper flight costs, could transform spaceflight. (....)
