SpaceX’s Starship rocket has become central to Elon Musk’s ambitions for the company, with its technological and commercial success underpinning a roughly $2 trillion valuation for SpaceX, Bloomberg reports.
Originally conceived as a vehicle to transport people to Mars, Starship is now expected to support multiple business ventures, including expanding the Starlink satellite network, potentially deploying up to 1 million spacecraft as artificial intelligence data centers and carrying astronauts to the moon and eventually Mars.
However, several major engineering challenges remain before the rocket can fulfill those goals. SpaceX must demonstrate that Starship can be fully and rapidly reused, withstand the extreme heat of atmospheric reentry, safely land both its upper spacecraft and booster and accommodate a wider range of commercial satellites and cargo through a redesigned deployment system.
Longer missions will also require unprecedented in-orbit refueling operations, potentially involving dozens of launches and the transfer of thousands of tons of supercooled liquid oxygen and methane, which must be kept cold to prevent fuel loss through evaporation. Although Starship has reached orbit, deployed batches of satellites and successfully returned its booster to Earth using its launch-tower catching system, SpaceX has yet to demonstrate a successful landing of the upper spacecraft or prove that its heat shield can withstand repeated flights with minimal repairs.
These milestones are critical as SpaceX lays the groundwork to eventually retire its Falcon 9 workhorse rocket. Musk has projected Starship launch costs could fall to $2 million to $10 million per flight, significantly below Falcon 9’s starting cost of $74 million. However, industry experts question whether those cost targets are achievable, even if SpaceX establishes a reliable, rapidly reusable launch system.
