During a "Powering Exploration Mission-1" ceremony in the Neil Armstrong Operations and Checkout Building high bay at NASA's Kennedy Space Center on Nov. 16, 2018, Amy Marasia, Orion Crew Module assembly lead for Exploration Mission-1 (EM-1), explains the next steps in processing Orion and the European Service Module (ESM). The event was held to mark a major milestone, the arrival of the European Service Module for Orion's Exploration Mission-1. The service module, built by the European Space Agency, will supply the main propulsion system and power to the Orion spacecraft during EM-1, a mission to the Moon. The ESM also will house air and water for astronauts on future missions. EM-1 will be an uncrewed flight test that will provide a foundation for human deep space exploration to destinations beyond Earth orbit. EM-1 will be the first integrated test of NASA's Space Launch System, Orion and the ground systems at Kennedy.

A view of Firing Room 1 in the Launch Control Center (LCC) at NASA's Kennedy Space Center in Florida. The Apollo and shuttle-era firing rooms in the LCC have been upgraded. The upper deck includes a work station in development for the EM-1 launch director. Exploration Ground Systems upgraded Firing Room 1 to support the launch of NASA's Space Launch System rocket and Orion spacecraft on Exploration Mission-1 and deep space missions.

A brilliant sunrise serves as the backdrop in this panoramic view of the mobile launcher at NASA's Kennedy Space Center in Florida. The mobile launcher is equipped with a number of lines, called umbilicals, which will connect to NASA's Space Launch System (SLS) and Orion spacecraft. Exploration Ground Systems is preparing the mobile launcher and ground systems necessary to process and launch the SLS and Orion spacecraft on Exploration Mission-1 and deep space missions.

From left, Jeremy Graeber, chief NASA test director; Jessica Parsons, technical assistant to the launch director; and Charlie Blackwell-Thompson, Exploration Mission-1 (EM-1) launch director, participate in a countdown demonstration event of cryogenic propellant loading April 12, 2019, inside Firing Room 2 in the Launch Control Center at NASA’s Kennedy Space Center in Florida. The practice simulation involved loading of liquid hydrogen and liquid oxygen into the Space Launch System rocket’s core and upper stages to prepare for Exploration Mission-1 (EM-1). During the tanking exercise, the team worked through surprise issues in real-time. The practice countdown events are training opportunities coordinated by Blackwell-Thompson with Exploration Ground Systems.

The European Service Module (ESM) is unpacked inside the Neil Armstrong Operations and Checkout Building high bay on Nov. 7, 2018, at NASA's Kennedy Space Center in Florida. The ESM is provided by the European Space Agency, and built by ESA contractor Airbus Defence and Space. It will supply the main propulsion system and power to the Orion spacecraft for Exploration Mission-1 (EM-1), a mission around the Moon. The ESM also will house air and water for astronauts on future missions. EM-1 will be an uncrewed flight test that will provide a foundation for human deep space exploration to destinations beyond Earth orbit. EM-1 will be the first integrated test of NASA's Space Launch System, Orion and the ground systems at Kennedy.

Mark Tripp, center, monitors his console in Firing Room 1 in the Launch Control Center at NASA’s Kennedy Space Center in Florida, during a terminal countdown demonstration for Exploration Mission 1, or EM-1, on Dec. 14, 2018. The launch will be the first integrated test of the Space Launch System rocket and Orion spacecraft that will eventually take astronauts beyond low-Earth orbit to destinations such as the Moon and Mars. The countdown demonstration was intended to validate the launch team's capability to perform an EM-1 countdown and respond to challenges put into the system for practice.
