Artemis I is the first integrated test of NASA’s deep space exploration systems: the Orion spacecraft, Space Launch System (SLS) rocket and the ground systems at the agency’s Kennedy Space Center in Florida. The first in a series of increasingly complex missions, Artemis I is an uncrewed flight test that will provide a foundation for human deep space exploration and demonstrate our commitment and capability to return humans to the Moon and extend beyond.
Launch site: Launch Pad 39B at NASA’s Kennedy Space Center in Florida
Launch date: Aug. 29, 2022
Launch window: 8:33 a.m. EDT to 10:33 a.m.
Mission Duration: 42 days, 3 hours, 20 minutes
Destination: distant retrograde orbit around the Moon
Total mission miles: approximately 1.3 million miles (2.1 million kilometers)
Targeted splashdown site: Pacific Ocean, off the coast of San Diego
Return speed: Up to 25,000 mph (40,000 kph)
Splashdown: Oct. 10, 2022
During this flight, Orion will launch atop the most powerful rocket in the world and fly farther than any spacecraft built for humans has ever flown. Over the course of the mission, it will travel 280,000 miles (450,000 kilometers) from Earth and 40,000 miles (64,000 kilometers) beyond the far side of the Moon. Orion will stay in space longer than any human spacecraft has without docking to a space station and return home faster and hotter than ever before.
This first Artemis mission will demonstrate the performance of both Orion and the SLS rocket and test our capabilities to orbit the Moon and return to Earth. The flight will pave the way for future missions to the lunar vicinity, including landing the first woman and first person of color on the surface of the Moon.
With Artemis I, NASA sets the stage for human exploration into deep space, where astronauts will build and begin testing the systems near the Moon needed for lunar surface missions and exploration to other destinations farther from Earth, including Mars. With Artemis, NASA will collaborate with industry and international partners to establish long-term exploration for the first time.
SLS and Orion will blast off from Launch Pad 39B at NASA’s modernized spaceport at Kennedy. Propelled by a pair of five-segment boosters and four RS-25 engines, the rocket will reach the period of greatest atmospheric force within 90 seconds. The solid rocket boosters will burn through their propellant and separate after approximately two minutes, and the core stage and RS-25s will deplete propellant after approximately eight minutes. After jettisoning the boosters, service module panels, and launch abort system, the core stage engines will shut down and the core stage will separate from the spacecraft, leaving Orion attached to the interim cryogenic propulsion stage (ICPS) that will propel it toward the Moon.
As the spacecraft makes an orbit of Earth and deploys its solar arrays, the ICPS will give Orion the big push it needs to leave Earth’s orbit and travel toward the Moon. This maneuver, known as the trans-lunar injection, precisely targets a point about the Moon that will guide Orion close enough to be captured by the Moon’s gravity
Orion will separate from the ICPS approximately two hours after launch. The ICPS will then deploy ten small satellites, known as CubeSats, along the way to study the Moon or head father out to deep space destinations. As Orion continues on its path from Earth orbit to the Moon, it will be propelled by a service module provided by ESA (European Space Agency) that will course-correct as needed along the way. The service module supplies the spacecraft’s main propulsion system and power.
The outbound trip to the Moon will take several days, during which time engineers will evaluate the spacecraft’s systems. Orion will fly about 60 miles (97 kilometers) above the surface of the Moon at its closest approach, and then use the Moon’s gravitational force to propel Orion into a distant retrograde orbit, traveling about 40,000 miles (64,000 kilometers) past the Moon. This distance is 30,000 miles (48,000 kilometers) farther than the previous record set during Apollo 13 and the farthest in space any spacecraft built for humans has flown.
For its return trip to Earth, Orion will get another gravity assist from the Moon as it does a second close flyby, firing engines at precisely the right time to harness the Moon’s gravity and accelerate back toward Earth, setting itself on a trajectory to re-enter our planet’s atmosphere.
The mission will end with a test of Orion’s capability to return safely to Earth. Orion will enter Earth’s atmosphere traveling at about 25,000 mph (40,000 kph). Earth’s atmosphere will slow the spacecraft down to a speed of about 300 mph (480 kph), producing temperatures of approximately 5,000 degrees Fahrenheit (2,800 degrees Celsius) and testing the heat shield’s performance.
Once the spacecraft has passed this extreme heating phase of flight, the forward bay cover that protects its parachutes will be jettisoned. Orion’s two drogue parachutes deploy first, at 25,000 feet (7,600 meters), and within a minute slow Orion to about 100 mph (160 kph) before being released. They are followed by three pilot parachutes that pull out the three main parachutes which will slow Orion’s descent to less than 20 mph (32 kph). The spacecraft will make a precise landing within eyesight of the recovery ship off the coast of San Diego.
The Landing and Recovery Team, led by NASA’s Exploration Ground Systems program at Kennedy, will be responsible for safely recovering the capsule after splashdown. The interagency landing and recovery team consists of personnel and assets from the U.S. Department of Defense, including Navy amphibious specialists and Air Force weather specialists, and engineers and technicians from Kennedy, Johnson Space Center in Houston, and Lockheed Martin Space Operations.
Before splashdown, the team will head out to sea in a Navy ship. At the direction of the NASA Recovery Director, Navy divers and other team members in several inflatable boats will be cleared to approach Orion. Divers will then attach a cable to the spacecraft and pull it by winch into a specially designed cradle inside the ship’s well deck. The vessel will transport the spacecraft and other hardware to a pier at U.S. Naval Base San Diego for transport to Kennedy.
Open water personnel will also work to recover Orion’s forward bay cover and three main parachutes. If teams are able to recover the jettisoned cover and parachutes, engineers will inspect the hardware and gather additional performance data.

The primary objectives of the Artemis I flight test are to demonstrate the Orion heat shield at lunar return re-entry conditions, demonstrate operations and facilities during all mission phases, and retrieve the spacecraft after splashdown. In the course of completing these goals, the team aims to successfully demonstrate the SLS rocket’s capability, carry out the mission as planned, and ensure a safe return prior to the first flight with crew on Artemis II. Additional secondary objectives will be accomplished as possible throughout the mission that may support future development or mission planning efforts. These objectives will enable NASA to evaluate the performance of Orion, SLS, and the supporting ground systems for certification of the respective systems that will support future crewed missions.
Demonstrate Orion’s heat shield can withstand the high speed and high heat conditions when returning through Earth’s atmosphere from lunar velocities When Orion returns from the Moon, it will be traveling nearly 25,000 mph (40,000 kph) and experience temperatures up to 5,000 degrees Fahrenheit (2,800 degrees Celsius) as it enters Earth’s atmosphere, much faster and hotter than a return from low-Earth orbit. While the heat shield has undergone extensive testing on Earth and was demonstrated on Exploration Flight Test-1 in 2014, no aerodynamic or aerothermal test facility can recreate the conditions the heat shield will experience returning at lunar return speeds. Validating heat shield performance is required before crews fly in Orion.
Demonstrate operations and facilities during all mission phases From launch countdown through recovery of Orion from the Pacific Ocean at the end of its mission, Artemis I provides an opportunity to test many aspects of NASA’s launch facilities and ground-based infrastructure, SLS operations, including separation events during ascent, Orion operations in space, and recovery procedures. During the flight, engineers will verify systems such as the spacecraft’s communications, propulsion, and navigation systems. Operating Orion in space will give engineers further confidence the spacecraft can tolerate the extreme thermal environment of deep space and successfully pass through the Van Allen Radiation Belt, that Orion’s main engine and solar array wings work as designed, and the flight operations teams can successfully manage and execute the mission, as well as demonstrate the performance of support systems for NASA facilities needed during the flight.
Retrieve Orion after splashdown While engineers will receive data throughout the flight, retrieving the crew module after splashdown will provide information to engineers to inform future missions. Once returned to Kennedy after the mission, technicians will conduct detailed inspections of Orion, retrieve data recorded on board during the flight, reuse components such as avionics systems, and retrieve information from payloads. It will also allow NASA to demonstrate its recovery techniques and procedures, which are critical to the safe return of future crews.
Accomplish additional flight test objectives A number of additional objectives will demonstrate other capabilities and aspects of the rocket, spacecraft, integrated systems, and recovery plans. Some of these flight test objectives include certifying Orion’s optical navigation system, deploying the 10 CubeSats riding inside the Orion stage adapter, operating the technology and biology payloads onboard Orion, and collecting imagery throughout the mission.

Before the Artemis I mission launches on its way around the Moon, the launch team at Kennedy and supporting teams across the country will begin the launch countdown about two days before liftoff.
The launch countdown contains "L Minus” and "T Minus" times. "L minus" indicates how far away liftoff is in hours and minutes and does not include built-in holds. “T minus” time is a sequence of events that are built into the launch countdown where counting and holds are inserted.
Pauses in the countdown, or "holds," are built into the countdown to allow the launch team to target a precise launch window, and to provide a cushion of time for certain tasks and procedures without impacting the overall schedule. For the Artemis I countdown, planned built-in holds vary in length and occur at the following times: L-8 hours 40 minutes, and L-40 minutes.
These key events will take place during the countdown.

The weather guidelines for Artemis I identify each condition that must be met to safely roll out to the pad and launch.
These guidelines include criteria for various meteorological conditions. Weather teams refer to these criteria while monitoring the elements and implement constraints when conditions could affect rollout or liftoff.
If other potential weather hazards exist beyond those in the guidelines, the launch weather team will report the hazardous condition to the launch director, who will determine whether launching would expose Artemis I to a weather hazard.
BASIC WEATHER CRITERIA FOR ROLL TO THE PAD
Do not roll to launch pad if the lightning forecast is greater than 10% within 20 nautical miles of the launch area during rollout.
Do not roll to launch pad if there is greater than a 5% chance of hail forecast in the launch area during rollout.
Do not roll to launch pad if the peak winds exceed 40 knots in the launch area during rollout.
Do not roll to launch pad if temperature is less than 40 degrees Fahrenheit or exceeds 95 degrees Fahrenheit at the launch area during rollout.
BASIC WEATHER LAUNCH CRITERIA AT THE PAD FOR LIFTOFF

Do not launch if the temperature at both 132.5 feet and 257.5 feet drops below a defined temperature constraint for 30 consecutive minutes. The temperature constraints range from 38 degrees Fahrenheit to 49 degrees Fahrenheit, depending upon the wind and relative humidity. Higher wind and relative humidity result in a colder temperature constraint.
Do not launch if the peak liftoff winds exceed a range of 29 knots through 39 knots between 132.5 feet and 457.5 feet, respectively.
Do not launch through upper-level wind conditions that could lead to control problems for the launch vehicle.

Artemis I will carry several payloads aboard SLS and Orion, including a number of technology demonstrations and science investigations, as well as mementos to be returned to Earth in Orion.
Small, low-cost science and technology experiments called CubeSats will deploy into deep space from the Orion stage adapter attached to the ICPS. These CubeSats are not much larger than a shoebox, weigh about 25 pounds (11 kilograms) each, and contain science and technology that may help pave the way for future human exploration in deep space. International space agency partners and universities are involved with several of the CubeSats.
Artemis I CubeSats are listed below with their provider, area of exploration:
Lunar IceCube – Morehead State University, Morehead, Kentucky Searching for water in all forms and other volatiles with an infrared spectrometer
LunaH-Map – Arizona State University, Tempe, Arizona Creating higher-fidelity maps of near-surface hydrogen in craters and other permanently shadowed regions of the lunar South Pole with neutron spectrometers
LunIR – Lockheed Martin, Denver, Colorado Performing advanced infrared imaging of the lunar surface
OMOTENASHI – JAXA, Japan Developing the world’s smallest lunar lander and studying the lunar environment
CuSP – Southwest Research Institute, San Antonio, Texas Measuring particles and magnetic fields as a space weather station

Three “passengers” will fly aboard Orion to test the spacecraft’s systems and collect data to inform future missions with astronauts.
Commander Moonikin CamposA suited manikin named Commander Moonikin Campos during a public contest will occupy the commander’s seat inside Orion to provide data on what crew members may experience in flight.
The manikin’s seat will be outfitted with two sensors – one under the headrest and another behind the seat – to record acceleration and vibration throughout the mission. Five additional accelerometers inside Orion will provide data to compare vibration and acceleration between the upper and lower seats. The Orion Crew Survival System suit – a spacesuit astronauts will wear during launch, entry, and other dynamic phases of their missions – worn by the manikin will also be equipped with two radiation sensors.
Helga and ZoharTwo additional seats in Orion will be occupied by manikin torsos, called phantoms, manufactured from materials that mimic human bones, soft tissues, and organs of an adult female. Named Zohar and Helga, the torsos will be fitted with more than 5,600 passive sensors and 34 active radiation detectors to measure radiation exposure as part of the Matroshka AstroRad Radiation Experiment (MARE), an international effort including the German Aerospace Center, the Israel Space Agency, and NASA.
Zohar will wear a radiation protection vest, called AstroRad, while Helga will not. The study will provide valuable data on radiation levels astronauts may encounter on lunar missions and evaluate the effectiveness of the protective vest that could allow crew to exit the storm shelter and continue working on critical mission activities in spite of a solar storm.
Additional Radiation Sensors
In addition to the CubeSats aboard the SLS rocket and the manikins inside the spacecraft, Orion will carry several additional instruments and investigations to study the radiation environment of deep space that is present for missions to the Moon and beyond.
Radiation Area Monitor (RAM)Radiation sensor technology aboard the spacecraft includes six Radiation Area Monitor (RAM) passive detectors about the size of a matchbox that will record the total radiation dose during the mission. As passive instruments, they require no source of power to collect radiation dose information and will be analyzed after the flight.
Hybrid Electronic Radiation Assessor (HERA)Orion also will be equipped with a radiation detector named the Hybrid Electronic Radiation Assessor (HERA) that will measure charged particles that pass through its sensors. As an active instrument attached to the spacecraft, it will be connected to power and also can send its readings to Earth during the flight. On crewed missions, HERA will be part of the spacecraft’s Caution and Warning System and will sound a warning in the case of a solar energetic particle event, notifying the crew to take shelter. NASA is also testing a similar HERA unit aboard the International Space Station.
ESA Active DosimetersCreated and provided by ESA, five devices each about the size of a deck of cards will be mounted inside the cabin and equipped with multiple sensors that cover a broad range of energies from ionizing radiation in space. Called ESA Active Dosimeters, the devices will record data on the radiation environment inside the spacecraft in real time with a timestamp to allow scientists to see radiation dose rates during various mission phases, as well as total mission dose. Scientists tested a similar ESA active dosimeter on the space station.
Biology Investigations Orion will also carry a payload called Biological Experiment-01 containing four space biology investigations. These investigations will look at the effects of the deep space environment on the nutritional value of seeds, DNA repair of fungi, adaptation of yeast, and gene expression of algae during the journey around the Moon. The experiments will take place inside a container stored within Orion’s crew module for the duration of Artemis I and will be returned to researchers for post-flight analyses after the spacecraft splashes down. The fundamental knowledge gained from these investigations will help us learn how we can better thrive in deep space, for future missions to the Moon and Mars.
Callisto is a technology demonstration developed through a reimbursable space act agreement with Lockheed Martin. Lockheed Martin has partnered with Amazon, and Cisco to bring the Alexa digital assistant and Webex video collaboration aboard Orion’s first flight test in deep space.
Named after a mythological Greek goddess and one of Artemis’ hunting attendants, Callisto is meant to show how commercial technology could assist future astronauts on deep space missions. The payload will demonstrate how astronauts and flight controllers can use human-machine interface technology to make their jobs simpler, safer and more efficient, and advance human exploration in deep space.
The industry-funded payload will be located on Orion’s center console and includes a tablet that will test Webex by Cisco video conferencing software to transmit video and audio from the Mission Control Center at Johnson, and custom-built hardware and software by Lockheed Martin and Amazon that will test Alexa, Amazon’s voice-based virtual assistant, to respond to the transmitted audio.

The Space Launch System rocket, Orion spacecraft, and ground systems at Kennedy Space Center in Florida are critical to NASA’s exploration plans at the Moon and beyond. NASA designed the SLS as the world’s most powerful rocket for safely sending humans on missions to deep space, and Orion is specifically designed to sustain humans hundreds of thousands of miles from home. Exploration Ground Systems (EGS) at Kennedy has the infrastructure to support the systems and facilities necessary to process and launch SLS and Orion. Together, SLS, Orion, and EGS are designed to meet the evolving needs of our nation’s deep space exploration program for decades to come.
OrionThe Orion spacecraft is specifically designed to carry astronauts to deep space and is currently the only spacecraft capable of crewed deep space flight and high-speed return from the vicinity of the Moon. Orion is composed of three main elements and supporting subsystems. The main elements are 1) the crew module, where astronauts live and work; 2) the service module, provided by ESA, which will provide power, propulsion, and thermal control; and 3) the launch abort system, which can pull the spacecraft and crew to safety in the event of an emergency during launch or ascent to orbit.
On deep space missions, both distance and duration dictate the capabilities and advanced technologies needed. Artemis I will test Orion’s navigation and communications systems beyond the range of GPS and above communication satellites in Earth orbit; test the radiation sensors and shielding outside the protection of Earth’s magnetic field; and test the world's largest heat shield during a high-speed return from the Moon, at nearly 25,000 mph and temperatures half as hot as the surface of the Sun.
Space Launch System (SLS)NASA’s Space Launch System (SLS) is the world’s most powerful rocket that provides the foundation for human exploration beyond Earth’s orbit and is currently the only rocket that can safely send Orion directly to the Moon. The main elements are 1) a central core stage that houses propellant tanks, engines, and avionics; 2) four liquid propellant RS-25 engines powered by cryogenic, or supercold, liquid hydrogen and liquid oxygen; 3) two solid-fuel rocket boosters that provide the majority of thrust and steering for the rocket during the first two minutes of flight; and 4) an upper stage fueled by liquid hydrogen and liquid oxygen for in-space propulsion after separation from the core stage.
SLS is designed specifically for deep space missions with humans and will send the Orion spacecraft to the Moon, which is nearly 1,000 times farther than where the International Space Station resides in low-Earth orbit. The rocket will provide the power to help Orion reach a speed of 22,600 mph, to escape the pull of Earth’s gravity send the spacecraft to the Moon.
Exploration Ground SystemsThe role of the Exploration Ground Systems (EGS) Program is to develop and operate the systems and facilities necessary to process, assemble, transport, and launch rockets and spacecraft at the NASA’s Kennedy Space Center in Florida. For Artemis missions, EGS is focused on the equipment, management, and operations required to safely connect the Orion spacecraft with the SLS rocket; move the rocket to the launch pad; successfully launch it into space; and recover the spacecraft once it has splashed down.
The main elements at Launch Complex 39 consist of 1) the 52-story Vehicle Assembly Building (VAB) for final assembly and testing of the rocket and spacecraft; 2) the mobile launcher that serves as the ground structure for stacking the rocket and spacecraft inside the VAB and from which the rocket will launch on the pad; 3) the crawler-transporter that will carry the rocket and spacecraft atop the mobile launcher along a crawlerway between the VAB and the pad; 4) the Launch Control Center, which contains the firing rooms for commanding the launch; and 5) Launch Pad 39B with electrical power, a water system, a flame trench, and a safe launch area to support SLS launches.

Artemis I will demonstrate NASA’s comprehensive communications network services for journeys to lunar orbit. The mission relies on NASA’s worldwide network infrastructure for seamless communications, providing different service levels as Orion leaves Earth, orbits the Moon, and returns safely home.
For Artemis I, NASA’s Near Space Network and NASA’s Deep Space Network will be used to support communication and navigation services. Communication services allow flight controllers to send commands to the spacecraft and receive data from Orion, the Space Launch System, and the rocket’s upper stage. Navigation, or tracking, services enable the flight controllers to calculate where the spacecraft are along their trajectory through space.
NASA’s Near Space NetworkNASA’s Near Space Network provides a suite of communications and navigation services through commercial and government-owned, contractor-operated network infrastructure. The network will provide communications and navigation services during launch and navigation services at various points on the journey to the Moon. Additionally, as Orion journeys back to Earth, the Near Space Network will provide communications and navigation services.
The Near Space Network’s Launch Communications Segment will provide links to both Orion and SLS during prelaunch and launch for Artemis I. NASA's constellation of Tracking and Data Relay Satellites (TDRS) will provide near-continuous communications services during launch and low-Earth orbit phases of the Artemis I mission. TDRS will continue service until Orion and ICPS leave its coverage volume, when NASA’s Deep Space Network takes over, and then provide service again on Orion’s return to Earth, from the final return trajectory correction burn through splashdown.
NASA’s Deep Space NetworkThe Deep Space Network will handle communications beyond low-Earth orbit. Additionally, the network will facilitate communications during the CubeSat deployments that will fly as secondary payloads on Artemis I with their own science and technology missions. The Near Space Network and Deep Space Network will work together to support navigation for Orion so that engineers can employ a technique called three-way Doppler tracking. With two ground stations on Earth in contact with Orion simultaneously – one from each network – NASA can triangulate Orion’s location relative to the ground stations.

Launch Control CenterThe Launch Control Center (LCC) at NASA’s Kennedy Space Center in Florida is where launch operations personnel will operate, monitor, and coordinate the launch of the SLS rocket and Orion spacecraft.
The LCC links the launch team operators inside Firing Room 1 to the SLS rocket and Orion spacecraft in processing areas such as the Vehicle Assembly Building, mobile launcher, and at Launch Complex 39B. Controllers at Kennedy are also able to communicate with controllers at the Space Launch Delta 45 Eastern Range and other NASA control centers from the LCC.
Mission Control CenterNASA’s Christopher C. Kraft Jr. Mission Control Center (MCC) at the Johnson Space Center in Houston is the facility from which flight operations personnel will remotely monitor and operate the Orion spacecraft and receive data from Orion and SLS.
MCC is comprised of several flight control rooms (FCR), including FCR-1, FCR-2 (the historic Apollo Flight Control Room) and the Red, White, and Blue FCRs. The White FCR was transformed from its shuttle legacy configuration into a modern mission control configuration known as the MCC-21 effort and is ultimately intended to serve as the mission control for flights of NASA's Orion spacecraft on missions to deep space destinations.
SLS Engineering Support CenterThe SLS Engineering Support Center is located in the Huntsville Operations Support Center at NASA’s Marshall Space Flight Center and allows engineers specializing in the engines, boosters, core stage, avionics, and upper stage to monitor the rocket’s propulsion and other systems during the countdown and flight.
The teams in the support center provide technical expertise to the launch operations team located in the LCC and the flight operations team located in the MCC. Support center teams also will provide help to solve challenges during the launch countdown and flight and produce flash reports and archive data for additional study in the weeks and months after launch

The primary teams responsible for supporting the mission include the mission management team, the launch control team, the flight control team, and the landing and recovery team. Throughout the mission, the mission management team is responsible for reviewing mission status and risk assessments for issues that arise and making relevant decisions. The launch control, flight control, and landing and recovery teams are responsible for operations throughout the mission phases. Additional support teams also provide technical expertise to the mission management team and each of the operations teams throughout the mission.
Mission Manager: Mike Sarafin Mike Sarafin is the Artemis mission manager at NASA Headquarters in Washington. In this role, he leads the Mission Management Team for Artemis I, providing oversight and responsibility for critical decisions across all flight phases (launch, in-space, and recovery), with support from team members and advisors with technical expertise in various areas. Prior to flight he acts as a senior technical leader that integrates mission requirements, mission planning, operations and flight readiness leading to mission execution.
Launch Director: Charlie Blackwell-ThompsonCharlie Blackwell-Thompson is the Artemis I launch director at NASA’s Kennedy Space Center in Florida, overseeing the countdown and liftoff of SLS and Orion. Named to the position in January 2016, Blackwell-Thompson is NASA's first female launch director. Her role includes leading and managing the launch operations planning and execution for the Exploration Ground Systems Program. She also serves as the cross-program lead to the Launch Integration team responsible for integration and coordination of launch operations across the three programs: SLS, Orion and EGS. In her role as launch director, she manages the development of all launch countdown plans, philosophy, and launch and scrub turnaround procedures and schedules, as well as training approaches.
Lead Flight Director: Rick LaBrode Rick LaBrode is the Artemis I lead flight director at NASA’s Johnson Space Center in Houston. In this role, he is responsible for guiding the flight control team in Mission Control to execute the mission objectives of the Orion spacecraft. LaBrode coordinates with teams to plan the mission design and strategy, develops procedures and flight rules on how to operate the spacecraft, and is responsible for the overall success of the mission, beginning with the Space Launch System rocket firing from space to propel Orion toward the Moon, through its trek back to Earth. As a flight director, LaBrode is involved in critical decision-making when needed and oversees the flight controllers who use real-time telemetry to track and monitor technical and safety aspects during the mission.
Ascent and Entry Flight Director: Judd Frieling Judd Frieling serves as the Artemis I ascent and entry flight director at Johnson. Frieling is responsible for two phases of flight: launch of the Orion spacecraft atop the Space Launch System (SLS) rocket as they clear the launch pad and climb toward the Moon, and Orion’s return from the lunar vicinity as it enters Earth’s atmosphere and splashes down in the ocean. From the Mission Control Center, Frieling oversees the flight control team – who have real-time command and control capability of the spacecraft – monitoring the launch performance of Orion and the SLS engines and its boosters, as well as the propulsions stages as the rocket clears the launch pad.
