Lili Villarreal fell in love with space exploration from an early age when she and her family visited the Kennedy Space Center Visitor Complex in Florida. So, it should come as no surprise that when the opportunity came for her to start working on NASA’s Artemis missions to explore the Moon and build the foundation for the first crewed mission to Mars, she jumped at it.
I was like, ‘Wow, we're going back to the Moon. I mean, how cool would it be to be at the beginning stages of that?'
Liliana Villareal
Artemis Landing & Recovery Director
She currently serves as the Artemis Landing and Recovery Director, helping retrieve the astronauts and Orion spacecraft after they splash down in the Pacific Ocean following their mission in space.
Originally from Cartagena, Colombia, Villarreal moved to Miami, Florida, when she was 10 years old with the goal of one day entering the aerospace industry. In 2007, her dream came true, and she became a part of the NASA team.
Prior to becoming the landing and recovery director, Villarreal served as the deputy flow director for the Artemis I mission, responsible for the integration, stacking, and testing of the SLS (Space Launch System) rocket and Orion spacecraft inside the Vehicle Assembly Building at the agency’s Kennedy Space Center.

“I kind of came in about a couple of years before we started processing Artemis I,” Villarreal said. “It took a while to get to the good parts of operations where it’s like, ‘Oh my god, we have everything here, and we’re starting to put everything together. And every day is a different day. Every day we have to figure out, ‘OK, what happened? How are we going to solve it?’ That’s the fun part about being an engineer out here.”
Throughout her NASA career, she’s also had the opportunity to work in the operations division for the International Space Station Program.
Every day I work on the Artemis missions, I imagine how the people who worked on Apollo felt because we are where they were back then.
Liliana Villareal
Artemis Landing & Recovery Director
Currently, she and the team are training for Artemis II – the first crewed mission under Artemis to send four astronauts around the Moon and back. Part of the training includes rehearsing the steps and procedures to make sure they’re ready for crewed flights. This includes conducting underway recovery tests where NASA and U.S. Navy teams practice retrieving astronauts from a representative version of Orion at sea and bringing them and the spacecraft back to the ship.
“I think it’s an amazing thing what we’re doing for humanity,” Villarreal said. “It’s going to better humanity, and it’s a steppingstone to eventually us living in other worlds. And I get to be part of that. You get to be part of that. How cool is that?”
Teams responsible for preparing and launching Artemis II at NASA’s Kennedy Space Center in Florida are set to begin a series of integrated tests to get ready for the mission. With the upper stage of the agency’s SLS (Space Launch System) integrated with other elements of the rocket, engineers are set to start the tests to confirm rocket and ground systems are working and communicating as planned.
While similar to the integrated testing campaign conducted for NASA’s uncrewed Artemis I test flight, engineers have added tests ahead of Artemis II to prepare for NASA’s first crewed flight under the Artemis campaign – an approximately 10-day journey by four astronauts around the Moon and back. The mission is another step toward missions on the lunar surface and helping the agency prepare for future astronaut missions to Mars.
Interface Verification Testing
Verifies the functionality and interoperability of interfaces across elements and systems. Teams will conduct this test from the firing room in the Launch Control Center and perform health and status checks of various systems and interfaces between the SLS core stage, the solid rocket boosters, and the ground systems. It will ensure different systems, including core stage engines and booster thrust control, work as planned. Teams also will perform the same series of tests with the interim cryogenic propulsion stage and Orion before conducting a final interface test with all segments.
Program Specific Engineering Test
Teams will conduct separate engineering tests for the core stage, rocket boosters, and upper stage following the interface verification tests for each part of the rocket.
End-to-End Communications Testing
Integrated test of SLS core and upper stages, and Orion command and telemetry radio frequencies with mission control at NASA’s Johnson Space Center in Houston to demonstrate flight controllers’ ability to communicate with the ground systems and infrastructure. This test uses a radio frequency antenna in the Vehicle Assembly Building (VAB), another near the launch pad that will cover the first few minutes of launch, as well as a radio frequency that use the Tracking Data Relay Satellite and the Deep Space Network. Teams will do two versions of this test – one with the ground equipment communicating with a radio and telemetry station for checkouts, and one with all the hardware and equipment communicating with communications infrastructure like it will on launch day.
Countdown Demonstration Test
Teams will conduct a launch day demonstration with the Artemis II astronauts to test launch countdown procedures and make any final necessary adjustments ahead of launch. This test will be divided into two parts. The first will be conducted while SLS and Orion are in the VAB and include the Artemis II crew departing their crew quarters after suiting up at the Neil A. Armstrong Operations and Checkout Building and driving to the VAB where they will enter Orion like they will on launch day and practice getting strapped in. Part two will be completed once the rocket is at the launch pad and will allow the astronauts and Artemis launch team to practice how to use the emergency egress system, which would be used in the event of an unlikely emergency at the launch pad during launch countdown.
Flight Termination System End-to-End Test
Test to ensure the rocket’s flight termination system can be activated in the event of an emergency. For public safety, all rockets are required to have a flight termination system. This test will be divided into two parts inside the VAB. The first will take place ahead of Orion getting stacked atop SLS and the second will occur before the rocket and spacecraft roll out to the launch pad.
Wet Dress Rehearsal
Teams will practice loading cryogenic liquid propellant inside SLS once it’s at the launch pad and run through the launch countdown sequences just prior to engine ignition. The rehearsal will run the Artemis II launch team through operations to load liquid hydrogen and liquid oxygen into the rocket’s tanks, conduct a full launch countdown, demonstrate the ability to recycle the countdown clock, and also drain the tanks to give them an opportunity to practice the timelines and procedures they will use for launch.
Teams will load more than 700,000 gallons of cryogenic, or super cold, propellants into the rocket at the launch pad on the mobile launcher according to the detailed timeline they will use on the actual launch day. They will practice every phase of the countdown, including weather briefings, pre-planned holds in the countdown, conditioning and replenishing the propellants as needed, and validation checks. The Artemis II crew will not participate in the rehearsal.

Engineers, technicians, mission planners, and the four astronauts set to fly around the Moon next year on Artemis II, NASA’s first crewed Artemis mission, are rapidly progressing toward launch.
At the agency’s Kennedy Space Center in Florida, teams are working around the clock to move into integration and final testing of all SLS (Space Launch System) and Orion spacecraft elements. Recently they completed two key milestones – connecting the SLS upper stage with the rest of the assembled rocket and moving Orion from its assembly facility to be fueled for flight.
“We’re extremely focused on preparing for Artemis II, and the mission is nearly here,” said Lakiesha Hawkins, assistant deputy associate administrator for NASA’s Moon to Mars Program, who also will chair the mission management team during Artemis II. “This crewed test flight, which will send four humans around the Moon, will inform our future missions to the Moon and Mars.”

On May 1, technicians successfully attached the interim cryogenic propulsion stage to the SLS rocket elements already poised atop mobile launcher 1, including its twin solid rocket boosters and core stage, inside the spaceport’s Vehicle Assembly Building (VAB). This portion of the rocket produces 24,750 pounds of thrust for Orion after the rest of the rocket has completed its job. Teams soon will move into a series of integrated tests to ensure all the rocket’s elements are communicating with each other and the Launch Control Center as expected. The tests include verifying interfaces and ensuring SLS systems work properly with the ground systems.
Meanwhile, on May 3, Orion left its metaphorical nest, the Neil Armstrong Operations & Checkout Facility at Kennedy, where it was assembled and underwent initial testing. There the crew module was outfitted with thousands of parts including critical life support systems for flight and integrated with the service module and crew module adapter. Its next stop on the road to the launch pad is the Multi-Payload Processing Facility, where it will be carefully fueled with propellants, high pressure gases, coolant, and other fluids the spacecraft and its crew need to maneuver in space and carry out the mission.
After fueling is complete, the four astronauts flying on the mission around the Moon and back over the course of approximately 10 days, will board the spacecraft in their Orion Crew Survival System spacesuits to test all the equipment interfaces they will need to operate during the mission. This will mark the first time NASA’s Reid Wiseman, Victor Glover, and Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen, will board their actual spacecraft while wearing their spacesuits. After the crewed testing is complete, technicians will move Orion to Kennedy’s Launch Abort System Facility, where the critical escape system will be added. From there, Orion will move to the VAB to be integrated with the fully assembled rocket.
NASA also announced its second agreement with an international space agency to fly a CubeSat on the mission. The collaborations provide opportunities for other countries to work alongside NASA to integrate and fly technology and experiments as part of the agency’s Artemis campaign.
While engineers at Kennedy integrate and test hardware with their eyes on final preparations for the mission, teams responsible for launching and flying the mission have been busy preparing for a variety of scenarios they could face.
The launch team at Kennedy has completed more than 30 simulations across cryogenic propellant loading and terminal countdown scenarios. The crew has been taking part in simulations for mission scenarios, including with teams in mission control. In April, the crew and the flight control team at NASA’s Johnson Space Center in Houston simulated liftoff through a planned manual piloting test together for the first time. The crew also recently conducted long-duration fit checks for their spacesuits and seats, practicing several operations while under various suit pressures.

Teams are heading into a busy summer of mission preparations. While hardware checkouts and integration continue, in coming months the crew, flight controllers, and launch controllers will begin practicing their roles in the mission together as part of integrated simulations. In May, the crew will begin participating pre-launch operations and training for emergency scenarios during launch operations at Kennedy and observe a simulation by the launch control team of the terminal countdown portion of launch. In June, recovery teams will rehearse procedures they would use in the case of a pad or ascent abort off the coast of Florida, with launch and flight control teams supporting. The mission management team, responsible for reviewing mission status and risk assessments for issues that arise and making decisions about them, also will begin practicing their roles in simulations. Later this summer, the Orion stage adapter will arrive at the VAB from NASA’s Marshall Spaceflight Center in Huntsville, Alabama, and stacked on top of the rocket.

Through Artemis, NASA will send astronauts to explore the Moon for scientific discovery, economic benefits, and build the foundation for the first crewed missions to Mars.
You would not expect to see NASA at a car show—but that’s exactly where Johnson Space Center employees were from Jan. 29 to Feb. 2, 2025, driving the future of space exploration forward.
At the Houston AutoBoative Show, a fusion of the auto and boat show, NASA rolled out its Artemis exhibit at NRG Center for the first time, introducing vehicle enthusiasts to the technologies NASA and commercial partners will use to explore more of the lunar surface than ever before.

The Artemis exhibit stood alongside some of the world’s most advanced cars and boats, offering visitors an up-close look at lunar terrain vehicle mockups from Astrolab, Intuitive Machines, and Lunar Outpost. Later this year, NASA will select the rover that will fly to the Moon as humanity prepares for the next giant leap.
In addition to the rovers, the exhibit featured a mockup of JAXA’s (Japan Aerospace Exploration Agency) pressurized rover, designed as a mobile habitat for astronauts, and Axiom Space’s lunar spacesuit, developed for Artemis III astronauts.
These capabilities will allow astronauts to explore, conduct science research, and live and work on the lunar surface.

Johnson Director Vanessa Wyche visited the Artemis exhibit to highlight the importance of these technologies in advancing lunar exploration. Every lesson learned on the Moon will help scientists and engineers develop the strategies, technologies, and experience needed to send astronauts to Mars.
“By bringing the excitement of lunar exploration to the AutoBoative Show, NASA aims to inspire the next generation of explorers to dream bigger, push farther, and help shape humanity’s future in space,” Wyche said.
NASA’s Artemis campaign is setting the stage for long-term human exploration, working with commercial and international partners to establish a sustained presence on the Moon before progressing to Mars.
To make this vision a reality, NASA is developing rockets, spacecraft, landing systems, spacesuits, rovers, habitats, and more.
