NASA Administrator Bill Nelson and NASA Exploration Ground Systems Program Deputy Manager Jeremy Parsons visit the agency’s SLS (Space Launch System) rocket core stage for the Artemis II mission inside NASA’s Kennedy Space Center in Florida on Thursday, Aug. 29, 2024. In the coming months, teams will integrate the rocket core stage atop the mobile launcher with the additional Artemis II flight hardware, including the twin solid rocket boosters, launch vehicle stage adapter, and the Orion spacecraft.

NASA Administrator Bill Nelson visits the agency’s Europa Clipper spacecraft inside the Payload Hazardous Servicing Facility at NASA’s Kennedy Space Center in Florida on Thursday, Aug. 29, 2024. Scheduled to launch later this year, Europa Clipper will embark on a 1.8-billion-mile (2.6-billion-kilometer) journey to Jupiter. It is the largest spacecraft NASA has developed for a planetary mission. Set to arrive in April 2030, it will study the gas giant’s icy moon, Europa, to determine its potential to support life.

NASA Administrator Bill Nelson visits Kennedy Space Center’s Launch Pad 39B in Florida, following the Space Launch System (SLS) rocket’s arrival at the pad on March 18, 2022. The rocket, with the Orion spacecraft atop, was carried from the Vehicle Assembly Building to the pad – a 4.2-mile journey that took nearly 11 hours to complete – by the agency’s crawler-transporter 2 for a wet dress rehearsal ahead of the uncrewed Artemis I launch. Artemis I will test SLS and Orion as an integrated system prior to crewed flights to the Moon. Through Artemis, NASA will land the first woman and the first person of color on the lunar surface, paving the way for a long-term lunar presence and serving as a steppingstone on the way to Mars.
