Late Saturday night, technicians at Kennedy Space Center in Florida moved the core stage for NASA\u2019s second Space Launch System rocket into position between the vehicle\u2019s two solid-fueled boosters.<\/p>\n

Working inside the iconic 52-story-tall Vehicle Assembly Building, ground teams used heavy-duty cranes to first lift the butterscotch orange core stage from its cradle in the VAB\u2019s cavernous transfer aisle, the central passageway between the building\u2019s four rocket assembly bays. The cranes then rotated the structure vertically, allowing workers to disconnect one of the cranes from the bottom of the rocket.<\/p>\n

That left the rocket hanging on a 325-ton overhead crane, which would lift it over the transom into the building\u2019s northeast high bay. The Boeing-built core stage weighs about 94 tons (85 metric tons), measures about 212 feet (65 meters) tall, and will contain 730,000 gallons of cryogenic propellant at liftoff. It is the single largest element for NASA\u2019s Artemis II mission, which is slated to ferry a crew of astronauts around the far side of the Moon as soon as next year.<\/p>\n

Finally, ground crews lowered the rocket between the Space Launch System\u2019s twin solid rocket boosters already stacked on a mobile launch platform inside High Bay 3, where NASA assembled Space Shuttles and Saturn V rockets for Apollo lunar missions.<\/p>\n

On Sunday, teams inside the VAB connected the core stage to each booster at forward and aft load-bearing attach points. After completing electrical and data connections, engineers will stack a cone-shaped adapter on top of the core stage, followed by the rocket\u2019s upper stage, another adapter ring, and finally the Orion spacecraft that will be home to the four-person Artemis II crew for their 10-day journey through deep space.<\/p>\n

Through the motions<\/h2>\n

This will be the first crewed flight of NASA\u2019s Artemis program, which aims to land astronauts on the lunar south pole and eventually build a sustainable human presence on the Moon, with an eye toward future expeditions to Mars. The program\u2019s first crewed lunar landing is penciled in for the Artemis III mission, again using SLS and Orion, but adding a new piece: SpaceX\u2019s enormous Starship rocket will be used as a human-rated lunar lander. Artemis II won\u2019t land, but it will carry people to the vicinity of the Moon for the first time since 1972.<\/p>\n

,<\/p>\n

The core stage for Artemis II arrived from its factory in Louisiana last year, and NASA started stacking the SLS solid rocket boosters in November. Other recent accomplishments on the path toward Artemis II include the installation of the Orion spacecraft\u2019s solar panels and closeouts of the craft\u2019s service module at Kennedy Space Center, with aerodynamic panels that will jettison during launch.<\/p>\n

As soon as next month, the Orion spacecraft will travel to a different facility at Kennedy for fueling, then to another building to meet its Launch Abort System before moving to the VAB for stacking atop the Space Launch System. Ahead of the uncrewed Artemis I mission in 2022, it took around eight months to complete these activities before delivering Orion to the VAB, so it\u2019s fair to be skeptical of NASA\u2019s target launch date for Artemis II in April 2026, which is already running years behind schedule.<\/p>\n

However, the slow march toward launch continues. A few months ago, some well-informed people in the space community thought there was a real possibility the Trump administration could quickly cancel NASA\u2019s Space Launch System, the high-priced heavy-lifter designed to send astronauts from the Earth to the Moon. The most immediate possibility involved terminating the SLS program before it flies with Artemis II.<\/p>\n

This possibility appears to have been overcome by circumstances. The rockets most often mentioned as stand-ins for the Space Launch System\u2014SpaceX\u2019s Starship and Blue Origin\u2019s New Glenn\u2014aren\u2019t likely to be cleared for crew missions for at least several years.<\/p>\n

The fully reusable Starship holds immense long-term promise to be significantly cheaper and more capable than the Space Launch System, but it suffered back-to-back failures to start the year, raising questions about SpaceX\u2019s upgraded Starship design, known as \u201cVersion 2\u201d or \u201cBlock 2.\u201d Once SpaceX irons out the design issues, it must prove it can recover and reuse Starships and test the vehicle\u2019s in-orbit refueling capabilities. Blue Origin\u2019s New Glenn had a successful debut flight in January, but its next flight is likely six or more months away.<\/p>\n

,<\/p>\n

NASA\u2019s existing architecture still has a limited shelf life, and the agency will probably have multiple options for transporting astronauts to and from the Moon in the 2030s. A decision on the long-term future of SLS and Orion isn\u2019t expected until the Trump administration\u2019s nominee for NASA administrator, Jared Isaacman, takes office after confirmation by the Senate.<\/p>\n

So what is the plan for SLS?<\/h2>\n

There are different degrees of cancellation options. The most draconian would be an immediate order to stop work on Artemis II preparations. This is looking less likely than it did a few months ago and would come with its own costs. It would cost untold millions of dollars to disassemble and dispose of parts of Artemis II\u2019s SLS rocket and Orion spacecraft. Canceling multibillion-dollar contracts with Boeing, Northrop Grumman, and Lockheed Martin would put NASA on the hook for significant termination costs.<\/p>\n

Of course, these liabilities would be less than the $4.1 billion NASA\u2019s inspector general estimates each of the first four Artemis missions will cost. Most of that money has already been spent for Artemis II, but if NASA spends several billion dollars on each Artemis mission, there won\u2019t be much money left over to do other cool things.<\/p>\n

Other options for NASA might be to set a transition point when the Artemis program would move off of the Space Launch System rocket, and perhaps even the Orion spacecraft, and switch to new vehicles.<\/p>\n

Another possibility, which seems to be low-hanging fruit for Artemis decision-makers, could be to cancel the development of a larger Exploration Upper Stage for the SLS rocket. If there are a finite number of SLS flights on NASA\u2019s schedule, it\u2019s difficult to justify the projected $5.7 billion cost of developing the upgraded Block 1B version of the Space Launch System. There are commercial options available to replace the rocket\u2019s Boeing-built Exploration Upper Stage, as my colleague Eric Berger aptly described in a feature story last year.<\/p>\n

For now, it looks like NASA\u2019s orange behemoth has a little life left in it. All the hardware for the Artemis II mission has arrived at the launch site in Florida.<\/p>\n

The Trump administration will release its fiscal-year 2026 budget request in the coming weeks. Maybe NASA will also have a permanent administrator by then, and the veil will lift over the White House\u2019s plans for Artemis.<\/p>\n","protected":false},"excerpt":{"rendered":"
