Florez is one of the NASA test directors for the Exploration Ground Systems Program. The test directors are a group of 20 engineers at the agency’s Kennedy Space Center in Florida who plan and execute integrated testing for Artemis missions. Their work includes developing timelines and procedures for launch countdown, propellant loading, emergency egress, pad and launch abort scenarios, recovery operations, and more. They help lead the ground systems team in all areas of testing.
At the time of Artemis I launch, Florez and his fellow test directors had already developed the launch countdown timelines for Artemis II.

With Artemis II, we’re going to have to do all that again, but in the middle of that, we’re going to have to embed the crew timeline to get the crew safely inside the spacecraft, get all the systems checked out, a …
