To the right is one of three lightning protection towers that surround the pad and protect the SLS and Orion from lightning strikes. Artemis I is the first integrated test of the SLS and Orion spacecraft. In future Artemis missions, NASA will land the first woman and the first person of color on the surface of the Moon, paving the way for a long-term lunar presence and serving as a steppingstone on the way to Mars.

Construction is complete on the main flame deflector in the flame trench at Launch Complex 39B at NASA's Kennedy Space Center in Florida. The flame deflector will safely deflect the plume exhaust from NASA's Space Launch System rocket during launch. It will divert the rocket's exhaust, pressure and intense heat to the north at liftoff. The Exploration Ground Systems Program at Kennedy is refurbishing the pad to support the launch of the SLS rocket and Orion on Exploration Mission-1, and helping to transform the space center into a multi-user spaceport.

A lightning strike was recorded at Launch Complex 39B at NASA’s Kennedy Space Center in Florida on June 10, 2022. NASA’s Space Launch System (SLS) and Orion spacecraft atop the mobile launcher are on the launch pad in preparation for the Artemis I mission. The lightning strike was recorded by cameras stationed at the pad and mobile launcher using a special filter called a “clear day frame,” which provides an overlay of the raw frame on a reference image. Artemis I will be the first integrated test of the SLS and Orion spacecraft. In later missions, NASA will land the first woman and the first woman of color on the surface of the Moon, paving the way for a long-term lunar presence and serving as a steppingstone on the way to Mars.

Artemis II backup crew member, CSA (Canadian Space Agency) astronaut Jenni Gibbons, participates in the Artemis II emergency egress demonstration, which is one of the integrated system verification and validation tests taking place at Launch Complex 39B at the agency’s Kennedy Space Center in Florida on Thursday, Aug. 8, 2024. The baskets, similar to gondolas on ski lifts, are used in the case of a pad abort emergency to enable astronauts and other pad personnel a way to quickly escape away from the mobile launcher to the base of the pad and where waiting emergency transport vehicles will then drive them away.

Crawler-transporter 2 (CT-2) makes its way along the crawlerway to Launch Complex 39B at NASA’s Kennedy Space Center in Florida on April 21, 2022. In view atop the mobile launcher on the pad are the Artemis I Space Launch System (SLS) and Orion spacecraft. The SLS and Orion atop the mobile launcher were transported to the pad on CT-2 for a prelaunch test called a wet dress rehearsal. Artemis I will be the first integrated test of the SLS and Orion spacecraft. In future Artemis missions, NASA will land the first woman and the first person of color on the surface of the Moon, paving the way for a long-term lunar presence and serving as a steppingstone on the way to Mars.

A view of Launch Complex 39B at NASA’s Kennedy Space Center in Florida on Oct. 23, 2020. The mobile launcher for Artemis I is at the pad. The nearly 400-foot-tall mobile launcher is at the pad while engineers with Exploration Ground Systems and Jacobs complete several tasks, including a timing test to validate the launch team’s countdown timeline, and a thorough, top-to-bottom wash down of the mobile launcher to remove any debris remaining from construction and installation of the umbilical arms. Artemis I will test the Orion spacecraft and Space Launch System as an integrated system ahead of crewed flights to the Moon. Under the Artemis program, NASA will land the first woman and the next man on the Moon in 2024.

Crawler-transporter 2 (CT-2) arrives on the surface of Launch Pad 39B for a fit check on May 22, 2018, at NASA's Kennedy Space Center in Florida. The test drive to the pad confirms that all of the recent modifications to CT-2 and Pad 39B are operational to support the launch of the agency's Space Launch System rocket and Orion spacecraft on Exploration Mission-1. In view, at left, is one of three lightning protection towers positioned around Pad 39B. Exploration Ground Systems managed the modifications and upgrades to CT-2 and Pad 39B to prepare for EM-1 and deep space exploration missions.

A close-up view of the flame trench and flame deflector at Launch Pad 39B at NASA's Kennedy Space Center in Florida on July 26, 2018. The launch pad has undergone upgrades and modifications to accommodate NASA's Space Launch System and Orion spacecraft for Exploration Mission-1 and other deep space missions. New heat-resistant bricks have been installed on the walls and a new flame deflector is in place. The clean pad concept is designed to support NASA and commercial launch providers at the multi-user spaceport.

About 450,000 gallons of water flow at high speed from a holding tank through new and modified piping and valves, the flame trench, flame deflector nozzles and mobile launcher interface risers during a wet flow test on May 24, 2018, at Launch Pad 39B at NASA's Kennedy Space Center in Florida. At peak flow, the water reached about 100 feet in the air above the pad surface. The test was performed by Exploration Ground Systems to confirm the performance of the Ignition Overpressure/Sound Suppression system. During launch of NASA's Space Launch System rocket and Orion spacecraft, the high-speed water flow will help protect the vehicle from the extreme acoustic and temperature environment during ignition and liftoff.

In view is the south side of the flame trench and the south side of the recently installed new main flame deflector. Exploration Ground Systems managed the modifications and upgrades to CT-2 and Pad 39B to prepare for EM-1 and deep space exploration missions.

About 450,000 gallons of water flow at high speed from a holding tank through new and modified piping and valves, the flame trench, flame deflector nozzles and mobile launcher interface risers during a wet flow test on May 24, 2018, at Launch Pad 39B at NASA's Kennedy Space Center in Florida. At peak flow, the water reached about 100 feet in the air above the pad surface. The test was performed by Exploration Ground Systems to confirm the performance of the Ignition Overpressure/Sound Suppression system. During launch of NASA's Space Launch System rocket and Orion spacecraft, the high-speed water flow will help protect the vehicle from the extreme acoustic and temperature environment during ignition and liftoff.

An aerial view shows workers preparing the surface of one of the three lightning protection system towers for painting at Exploration Ground Systems’ Launch Complex 39B at NASA’s Kennedy Space Center in Florida on May 30, 2019. The old paint was removed by the most recent hurricane. Pad 39B is the site of future launches of the agency’s Space Launch System rocket with the Orion spacecraft on Artemis missions. The 600-foot-tall lightning towers will help prevent lightning strikes at the pad during prelaunch and launch activities.

Teams at NASA’s Kennedy Space Center in Florida practice the Artemis mission emergency procedures during a series of integrated system verification and validation tests at Launch Pad 39B on Friday, Aug. 9, 2024. Members of the closeout crew, pad rescue team, and the Exploration Ground Systems Program practiced the process of getting inside and out of the emergency egress baskets. While the crew and other personnel will ride the emergency egress baskets to the terminus area in a real emergency, no one rode the baskets for this test. Instead, teams tested the baskets during separate occasions by using water tanks filled to different levels to replicate simulate the weight of passengers.

A portion of the mobile launcher and umbilical connections are in view, as well as the crew access arm. The SLS and Orion atop the mobile launcher were transported to the pad on crawler-transporter 2 for a prelaunch test called a wet dress rehearsal. Artemis I will be the first integrated test of the SLS and Orion spacecraft. In future Artemis missions, NASA will land the first woman and the first person of color on the surface of the Moon, paving the way for a long-term lunar presence and serving as a steppingstone on the way to Mars.
