Members of the media get an up-close look at the integrated twin SLS (Space Launch System) solid rocket boosters for Artemis II inside the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida during Artemis Media Day on Friday, March 7, 2025. The twin solid boosters will help support the remaining rocket components and the Orion spacecraft during final assembly of the Artemis II Moon rocket and provide more than 75 percent of the total SLS thrust during liftoff from NASA Kennedy’s Launch Pad 39B.

Members of the media get an up-close look at the SLS (Space Launch System) rocket core stage for Artemis II inside the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida during Artemis Media Day on Friday, March 7, 2025. The core stage has two giant propellant tanks that collectively hold more than 733,000 gallons of super cold liquid propellant to feed the stage’s four RS-25 engines to help send astronauts inside NASA’s Orion spacecraft to venture around the Moon for Artemis II.
