Starship Prototype Unveiled (space.com)

Article summary

SpaceX has unveiled its Starship prototype, a reusable launch system designed to carry up to 100 people to the moon, Mars, and other destinations. The Starship is made of stainless steel, which was chosen for its strength, durability, and cost-effectiveness. Elon Musk expects the Starship to be able to reach orbit in less than six months and to start carrying people within the next year or so. The Starship is a key part of SpaceX's goal to make humanity a multiplanet species.

What commenters say

• The welding process for the Starship's steel construction is a complex and highly skilled task, requiring great precision and attention to detail. Some commenters believe that the use of steel for the Starship's construction is a cost-effective and practical choice, while others think it may not be the best material for a spacecraft. The production of the Raptor engines is seen as a bottleneck in the development of the Starship, with a goal of producing one engine per day. The use of a helical weld or a single seam weld is discussed as a potential method for reducing the number of welds and improving the structural integrity of the Starship. The construction of the Starship is compared to other industrial welding tasks, such as building water towers, but with much higher precision and safety requirements. Some commenters are skeptical about the feasibility of the Starship's development timeline and the ability to reach orbit in less than six months. The choice of steel over other materials, such as carbon fiber, is defended as a pragmatic decision based on cost and availability.
