It’s not often that a single Washington signature might decide how fast a 5,000-ton stainless steel rocket gets to the Moon. But President Donald Trump’s new executive order, intended to remove layers of federal review for commercial rocket launches, has the potential to do just that speeding up, or derailing, the most ambitious spacecraft program in recent aerospace history: SpaceX’s Starship.
The order instructs the U.S. transportation secretary to “eliminate or expedite” environmental assessments for launch and reentry permits regulated by the Federal Aviation Administration, and to remove “outdated, redundant or overly restrictive rules” governing commercial spaceflight. Practically speaking, this is aimed at the FAA’s environmental impact analyses, post-flight accident investigations, and licensing reviews processes that have consistently slowed Starship’s test pace at SpaceX’s South Texas Starbase.
SpaceX’s engineering culture is based on quick iteration, flying prototypes to destruction and reassembling them in weeks. But that methodology has run headlong into the FAA’s requirement to protect the public and environment. Following two Starship explosions early this year sprayed debris across the Caribbean and caused dozens of airliners to make detours, the FAA grounded flights for almost two months, subsequently expanding hazard areas along launch flight paths. Musk has described such delays as an innovation brake, especially for a vehicle that serves as the basis for his vision for Mars as well as NASA’s Artemis lunar mission.
The stakes are high. Starship is not simply another rocket it is NASA’s selected Human Landing System for Artemis 3 and Artemis 4, intended to carry astronauts to the south pole of the Moon. The architecture of this vehicle is unprecedented: a two-stage, 33 Raptor-powered methane-fueled system on the Super Heavy booster and six on the Starship upper stage. Lunar missions will see the Starship HLS variant jettison Earth reentry hardware, install five deployable solar panels, and use high-mounted thrusters for final descent to prevent blasting regolith into lethal clouds.
Putting that lander into lunar orbit will involve a sophisticated chain of orbital refueling. A depot Starship will launch first, then as many as 20 tanker flights carrying 2 million pounds of cryogenic methane and oxygen. Then and only then can the crew-rated HLS Starship refuel for its translunar injection. This choreography relies on high launch cadence precisely what Trump’s order attempts to facilitate by relaxing FAA regulation and simplifying Part 450 licensing rules, which were themselves designed to make approvals easier but have been found to be ill-suited for fast-changing vehicles like Starship.
The FAA’s licensing procedure is not light. It needs to verify compliance with U.S. national interests, environmental regulations, and public safety. Launch pads such as Boca Chica are located close to sensitive environments; Starship’s April 2023 launch destroyed its pad, shooting concrete six miles, starting a grass fire, and burning up wildlife nests. Environmentalists contend that skipping National Environmental Policy Act reviews jeopardizes repeating such events at increased frequency. Jared Margolis of the Center for Biological Diversity cautioned, This irresponsible order threatens people and wildlife with private companies firing huge rockets that frequently explode and cause destruction on the ground around them.
From the engineering perspective, the pressure is evident. The Artemis timeline at NASA is already stressed by Starship development delays, heat shield wear on Orion, and Axiom’s AxEMU spacesuit work. Officially, Artemis 3 is targeted for mid-2027, but NASA internal baselines are for February 2028 or beyond. Super Heavy’s current payload-to-orbit capability approximately 50 tons as opposed to its 100-ton goal could double the frequency of tanker flights and extend refueling schedules to six months, jeopardizing mission feasibility.
The March 14 integrated flight test of Super Heavy and Starship was a step forward. The booster’s 33 Raptors powered the stacks out of Starbase, hot-staged upper-stage separation, and Starship executed a full-duration ascent burn. A milestone was the in-orbit transfer of thousands of pounds of cryogenic propellant between internal tanks a first-of-its-kind demonstration vital for lunar and Mars missions. Cryogenic propellant storage and transfer in space has never been done at this kind of scale, noted Jeremy Kenny, manager of NASA’s Cryogenic Fluid Management Portfolio. But this is game-changing technology that needs to be developed and matured.
Trump’s directive extends beyond Starship, too. Blue Origin’s Blue Moon lunar lander, targeted for Artemis 5, may benefit from accelerated licensing, as might spaceport expansions at Cape Canaveral, Vandenberg, and Wallops. The order even promotes the Office of Space Commerce to regulate “novel space activities” like in-orbit production and asteroid mining. Transportation Secretary and Acting Administrator of NASA Sean Duffy presented it as opening up “the next wave of innovation” by eliminating “red tape holding up spaceport construction” and allowing launches “at scale.”
For aerospace engineers and policy analysts, the math is complicated. Deregulation may shorten development cycles for aircraft that require high rates of flight to develop. However, it also places responsibility for managing risk on operators’ shoulders, with implications for environmental management, public protection, and the robustness of national aspirations in space in case one operator fails. When it comes to the competition to the Moon and ultimately Mars the equation for speed vs. safety is now being rewritten at the most senior levels of government.
