T024 // SpaceX’s Production Ambitions

SpaceX, led by Elon Musk, aims to produce one Starship spacecraft per day. Each Starship is designed to carry 150 tons to low Earth orbit (LEO) and has a lifespan of at least 100 launches. This goal represents a significant leap in space transportation capabilities and aims to drastically reduce the cost of sending payloads into space.

Each Starship can launch 15,000 tons of payload into orbit over its operational life. To put this into perspective, this is almost equivalent to the total mass launched into space from 1957 to 2023. A single Starship can double the current man-made mass in space and lift the equivalent of over 30 International Space Stations.

With the planned production rate, SpaceX could potentially place millions of tons into orbit annually. This scale would be enough to launch over 10,000 International Space Stations in one year. Such an increase in launch capacity is expected to lead to a dramatic reduction in launch costs.

According to Wright's Law, which suggests that costs decrease with increased production, the cost per kilogram for launch will significantly drop with cumulative launch mass. The projected cost evolution per kilogram of payload based on Starship production is as follows:

• Unit #1: $1000/kg

• Unit #3: $700/kg

• Unit #7: $490/kg

• Unit #15: $343/kg

• Unit #31: $240/kg

• Unit #63: $168/kg

• Unit #127: $117/kg

• Unit #255: $82/kg

• Unit #511: $57/kg

Musk has indicated that costs could drop as low as $10/kg. Depending on the learning rate, this could be achieved with as few as a dozen units or as many as 15,000 units. Historical precedents, such as cost reductions in shipbuilding during WWII, suggest that such price drops are feasible.

While many Starship launches will be dedicated to refueling missions, enabling payloads to travel further into space, the overall payload capacity and associated cost reductions will still be substantial.

The implications of SpaceX's Starship production plan are profound. Lower launch costs will open up space to a wider range of activities and industries. For example, space-based solar power (SBSP) becomes more viable with reduced launch costs. Currently, at a conservative estimate of 100kW of SBSP per ton of satellite launched, one Starship could place at least 15MW per launch into orbit and 1.5GW over its lifetime. With advancements in solar technology and launch capacity, these figures could increase even further.

This scale of operation can significantly contribute to solving the launch problem for SBSP and other heavy-lift requirements. The potential for cost-effective, frequent, and large-scale access to space paves the way for new space ventures and commercial opportunities, fundamentally altering our approach to space exploration and utilization.

SpaceX's ambitious plan to produce one Starship per day promises to disrupt space transportation, drastically reduce costs, and enable new technologies and industries to thrive in space. The impact of such advancements will be felt across various sectors, highlighting the importance of continued innovation and investment in space capabilities.
