Starship is Still Not Understood (2021)

Starship has evolved into a nearly complete prototype, aiming to reduce launch costs and enable large-scale missions to the Moon and Mars, necessitating a reevaluation of current space mission designs.

Starship is Still Not Understood (2021)

Starship, SpaceX's ambitious rocket project, has made significant progress over the past two years, evolving from a design concept to a nearly complete prototype. Despite this advancement, there remains a lack of understanding within the space community regarding its potential impact. Starship aims to revolutionize space logistics by enabling the transport of over 100 tons of cargo to Low Earth Orbit (LEO) for less than $10 million per launch, with the capability to support thousands of launches annually. This could facilitate large-scale missions to the Moon and Mars, potentially transporting a million tons of cargo to Mars in just ten launch windows. However, the current space mission designs are still constrained by outdated mass limitations, which Starship's capabilities could render obsolete. The Artemis program, for instance, has not been redesigned to fully utilize Starship's potential, reflecting a broader organizational reluctance to adapt to this new paradigm. The author argues that the space industry must begin to prepare for the changes Starship could bring, as ignoring its potential could lead to strategic disadvantages. The future of space exploration could be dramatically altered if Starship succeeds, making it essential for stakeholders to rethink their approaches and embrace the possibilities it offers.

- Starship has progressed from a concept to a nearly complete prototype in two years.

- It aims to reduce launch costs significantly, enabling large-scale missions to the Moon and Mars.

- Current space mission designs are still limited by outdated mass constraints.

- The Artemis program has not been adapted to leverage Starship's capabilities.

- The space industry must prepare for the potential changes Starship could bring to exploration and logistics.

> Starship is intended to be able to transport a million tonnes of cargo to the surface of Mars in just ten launch windows

Again, this is from 2021, one of those set of launches was to be last year. And it was to be 1,000 starships bound for Mars to meet that goal.

Starship is impressive but we need to be realistic about these numbers. We haven’t even technically had a launch with any payload. Additionally they claim that within 2 years of the Artemis mission we could get 1,000 people on the moon (though say this isn’t going to happen at least).

Starship will make Starlink V2 feasible and dozens if not hundreds of missions that would otherwise never be possible. But getting 1 million people to Mars (or even 1,000 people to the Moon) is just fantasy. I will gladly eat crow but none of these capabilities that exist on paper have actually been demonstrated that are necessary to meet these goals. SapceX is the best there is and likely will get to Mars. Just not how Musk describes it.

Tell me why I shouldn't be concerned about thousands of starships launching from Earth and emitting multiple megatons of Carbon Dioxide in the fragile upper atmosphere? Some studies indicate emissions here are significantly more impactful, and can also damage the Ozone layer as well.

Any answers shouldn't consist of "well it's a fraction of what the aviation industry emits" because _the entire point_ of Starship is to scale-up to aviation-like operations.

I thought it was an interesting way to put it that:

the JPL produces things at $1,000,000/kg, and that inside the engineering organization it'll be hard to reconfigure everyone's mindsets and practices to create stuff that doesn't spend so much money / is less concerned with weight.

From an engineering perspective it seems like simply putting less into a finished product would be easy, but his argument is basically that the design parameters for every single thing produced are so fundamentally oriented towards weight (and size maybe?) that it's very hard to turn around. (This is not exactly the government spending / misaligned incentive argument that is made for many government projects- my read was that this is a subtly different problem.)

> aero flaps had never been demonstrated

Does he mean grid fins? Because "flaps" are something else entirely.

Grid fins have been around since the 1950s.

The article say the cost to orbit is/was $10,000/kg.

Anyone know what it is now? What it will/would be with Starship?

Feel's like we're finally conquering the gravity well!
