We got a nice treat today, over at Launch Complex 39B. Our Space Coast Live cameras caught an SLS Emergency Egress System test! Should crew need to get out of there in a hurry, they would just take the slidewire basket system down to a safe distance! (video is in real time) Keep tabs on everybody's favorite big orange rocket using our 24/7 livestream, linked in the comments below. 👇 | NASASpaceflight.com

The SLS mega-rocket has reached the launch pad as NASA gears up for Artemis II, the first astronaut-crewed flight of the Artemis program. This mission will fly a crew around the Moon to validate spacecraft systems and clear the way for long-duration lunar and deep-space exploration. | Interesting Engineering
