NASA has delivered a specialized weather cover to the Kennedy Space Center in Florida, designed to protect the core stage of the Space Launch System (SLS) rocket. Transported via the barge Pegasus, the circular, saucer-like component will shield the massive rocket stage from Florida’s volatile coastal weather as teams assemble the hardware for the upcoming Artemis 3 mission.
Why is NASA using a “flying saucer” component for the SLS?
While the circular, flattened shape of the new weather cover has drawn visual comparisons to a “flying saucer,” NASA confirms the object is strictly a functional piece of aerospace infrastructure. According to agency reports, the component acts as an environmental barrier to safeguard the core stage of the Space Launch System from moisture, wind, and debris. The hardware arrived at the Kennedy Space Center earlier this week, arriving on the same Pegasus barge previously used to transport the Nancy Grace Roman Space Telescope, which will be launched at the end of August.
The Pegasus barge, which delivered the weather cover, serves as a critical logistics link for NASA. It is frequently tasked with moving large-scale hardware, including the Nancy Grace Roman Space Telescope, which is scheduled for launch in late August.
How does the SLS assembly process work for Artemis 3?
Assembly of the Artemis 3 rocket is currently underway inside the Vehicle Assembly Building (VAB) at the Kennedy Space Center. NASA began the integration process several weeks ago, following the arrival of the core stage in April. Workers began the complex task of stacking the massive structure in May. The SLS stands nearly 100 meters tall and serves as the primary launch vehicle for the Orion crewed spacecraft.
What is the current status of the Artemis lunar program?
NASA has shifted the timeline for its lunar landing goals to account for technical testing. While the agency originally targeted 2027 for a human return to the Moon via Artemis 3, mission parameters have evolved. NASA now plans to conduct orbital tests near Earth, including docking procedures between the Orion spacecraft and lunar landers, before attempting a lunar surface mission. These tests are now slated to occur ahead of the Artemis 4 mission. To date, the SLS has flown twice: during the Artemis 1 and 2 missions, the latter of which saw astronauts return to the vicinity of the Moon for the first time in over 50 years.

Frequently Asked Questions
What is the circular object delivered to the Kennedy Space Center?
It is a weather cover designed to protect the core stage of the Space Launch System (SLS) rocket from Florida’s harsh environmental conditions during assembly.
Is the SLS rocket currently being built for Artemis 3?
Yes. NASA began assembling the SLS for Artemis 3 in May at the Vehicle Assembly Building following the arrival of the core stage in April.
Why was the Artemis 3 lunar landing date changed?
NASA adjusted the program to prioritize orbital testing of docking systems between the Orion spacecraft and lunar landers, moving the crewed lunar surface landing to the Artemis 4 mission.
How tall is the Space Launch System rocket?
The SLS is an immense structure, standing nearly 100 meters in height.
