On April 10, 2024, the Artemis II Orion spacecraft is seen inside the west altitude chamber in the Operations and Checkout Building at NASA's Kennedy Space Center in Florida, where it will undergo electromagnetic interference and compatibility testing.

Technicians install four solar array wings on NASA’s Artemis II Orion spacecraft inside the Neil A. Armstrong Operations and Checkout Building at NASA’s Kennedy Space Center in Florida on Monday, March 3, 2025. Each solar array is nearly 23 feet long and can turn on two axes to remain aligned with the Sun for maximum power. Orion’s solar arrays, manufactured and installed by ESA (European Space Agency) and its contractor Airbus, will deliver power to the service module that provides propulsion, thermal control, and electrical power to the spacecraft, as well as air and water for the crew.

Teams with NASA and Lockheed Martin prepare to conduct testing on NASA’s Orion spacecraft on Thursday, Nov. 7, 2024, in the altitude chamber inside the Neil A. Armstrong Operations and Checkout building at NASA’s Kennedy Space Center in Florida. The altitude chamber simulates deep space vacuum conditions, and the testing will provide additional data to augment data gained during testing earlier this summer. The Orion spacecraft will carry NASA astronauts Victor Glover, Christina Koch, and Reid Wiseman, as well as CSA (Canadian Space Agency) astronaut Jeremy Hansen, on a 10-day journey around the Moon and back for the Artemis II test flight.

The Artemis II Orion spacecraft sits in the transfer aisle in the Neil A. Armstrong Operations and Checkout Building at NASA’s Kennedy Space Center in Florida in preparation for the installation of three spacecraft adapter jettison fairings on Tuesday, March 11, 2025. The fairings encapsulate the service module and protect the solar array wings, shielding them from the heat, wind, and acoustics of launch and ascent, plus help redistribute the load between Orion and the massive thrust of the SLS (Space Launch System) rocket during liftoff and ascent. Once the spacecraft is above the atmosphere, the three fairing panels will separate from the service module reducing the mass of the spacecraft.
