A cover, called a “spider” is attached to the SLS (Space Launch System) rocket core stage for NASA’s Artemis II mission inside the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida on Monday, Oct. 28, 2024. Teams with Exploration Ground Systems will use a crane to attach to the spider cover to raise the core stage vertically. 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.

Teams with NASA’s Exploration Ground Systems Program lift the agency’s SLS (Space Launch System) core stage for the Artemis II mission from horizonal to vertical inside the transfer aisle at the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida on Tuesday, Dec. 10, 2024. The one-of-a kind lifting beam is designed to move the core stage from the transfer aisle to High Bay 2 where it will remain while teams stack the two solid rocket boosters for the SLS core stage.

Teams with Exploration Ground Systems prepare to attach a cover, called a “spider” to the top of the SLS (Space Launch System) rocket core stage for NASA’s Artemis II mission on Friday, Oct. 25, 2024, at NASA’s Kennedy Space Center in Florida. Once connected, a crane will attach to the spider cover to raise the core stage vertically. 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.
