NASA and SpaceX are exploring ways to make lunar landings faster and safer. Recently, SpaceX mentioned a “simplified” version of its Starship system to help NASA return humans to the Moon more quickly. This idea could change how we approach lunar missions, but it raises questions about what exactly a pared-down plan would look like.

Right now, NASA is working with SpaceX and Blue Origin to develop lunar landers. NASA’s interim leader, Sean Duffy, said they’re asking these companies for more flexible, faster plans. SpaceX responded by sharing their thoughts on a simplified mission architecture that could speed up the process while keeping crew safety high. But what does “simplified” really mean?

To understand, it’s helpful to set some ground rules. First, any new plan shouldn’t involve major changes to existing hardware. That rules out creating a tiny, stubby version of Starship, which would need a complete redesign. Instead, the focus is on using existing Starship parts as they are, just rearranged or used differently.

Second, SpaceX would likely stick with the same contractors involved in Artemis III. That means no big new partnerships, just tweaks to what’s already in place. With these rules, there are two main ideas being discussed: using expendable Starships for fuel missions and a concept called “Enter the Dragon.”

Using Expendable Starships to Cut Costs and Time

One big challenge in the current plan is fueling Starship in orbit. SpaceX needs to launch a fuel depot into space, then send several tanker Starships to fill it up before the lunar Starship can take off. This process involves multiple launches and can be slow and expensive. Experts estimate it could take anywhere from a dozen to 40 tanker launches to fully fuel the lunar Starship, depending on the design and efficiency.

A way to speed this up is to use expendable Starships for fueling, rather than reusing them. This means launching fuel tanks that are only used once, which could save weight and complexity. SpaceX could remove parts like grid fins and heat shields that aren’t needed for these fuel-only missions, reducing mass and increasing payload capacity.

Using expendable tankers might cut the number of launches needed by about half. However, this approach has drawbacks. It would increase costs since the rockets aren’t reused. It also conflicts with SpaceX’s big vision of rapid reuse and high launch frequency. Elon Musk and other leaders see Starship as a game-changer that will launch many times a month, making expendable rockets less appealing.

Relying Fully on SpaceX Hardware for Moon Landings

Another idea is to skip NASA’s traditional Orion and SLS system altogether. Instead, SpaceX could develop a simplified lunar mission using only its Starship spacecraft. This approach would involve launching Starship into orbit, fueling it with depots, and then landing astronauts on the Moon.

In this scenario, SpaceX would send two fuel depots into orbit—possibly requiring three to five launches each—and then transfer fuel to the lunar Starship. A crew of four astronauts would launch on Crew Dragon, dock with the lunar Starship, and make the trip to the Moon. After their surface stay, the Starship would refuel in lunar orbit from one of the depots, then return to Earth.

This plan sounds complicated, but it might actually be simpler than NASA’s Orion-based mission. It avoids the need for long loiter times and complex rendezvous in high orbits. However, it raises safety concerns, especially about fueling with crew onboard in lunar orbit. NASA officials have historically been cautious about fueling rockets with astronauts still on board, citing safety risks.

In summary, a simplified Starship plan could help NASA achieve its Moon goals faster and more efficiently. Whether through using expendable fuel ships or relying solely on SpaceX hardware, these ideas aim to cut down on time, cost, and complexity. But each approach has trade-offs that must be carefully considered before moving forward.
