Preparations for Next Moonwalk Simulations Underway (and Underwater)
Stephanie Dudley, Gateway’s mission integration and utilization manager, sits inside a high-fidelity HALO (Habitation and Logistics Outpost) mockup at NASA’s Johnson Space Center.NASA/Josh Valcarcel Stephanie Dudley sits at the intersection of human spaceflight and science for Gateway, humanity’s first lunar space station that will host astronauts and unique scientific investigations.
Gateway’s mission integration and utilization manager, Dudley recently posed for this photo in a high-fidelity mockup of the space station’s HALO (Habitation and Logistics Outpost), where astronauts will live, conduct science, and prepare for missions to investigate the lunar South Pole region. Dudley works with NASA’s partner space agencies and academia to identify science opportunities on Gateway.
HALO will host various science experiments, including the Heliophysics Environmental and Radiation Measurement Experiment Suite, led by NASA, and the Internal Dosimeter Array, led by ESA (European Space Agency) and JAXA (Japan Aerospace Exploration Agency). The heliophysics experiment will fly on HALO’s exterior, and the dosimeter will be housed inside Gateway in a series of racks, mockups of which are shown to the right of Dudley in the image above. Both experiments will study solar and cosmic radiation to help the science community better understand how to protect astronauts and hardware during deep space travels to places like Mars.
“We are building [Gateway] for a 15-year lifespan, but definitely hope that we go longer than that,” Dudley recently said on Houston We Have a Podcast. “And so that many years of scientific study in a place where humans have never worked and lived long-term, Gateway is going to allow us to do that.”
Dudley pulls double duty as a deputy director for the Exploration Operations Office within NASA’s Moon to Mars Program, a role that connects her to Artemis science beyond Gateway, including science investigations on the Orion and Human Landing System spacecraft and lunar terrain vehicle.
“My work…is helping to make sure that across all of the six [Artemis] programs, including Gateway, we’re all focusing on utilization in the same way,” Dudley said.
Dudley’s team coordinates science payloads for Artemis II, the first mission to send humans to the Moon since 1972, and Artemis III, the first landing in the lunar South Pole region that is of keen interest to the global science community.
Gateway’s HALO will launch with the space station’s Power and Propulsion Element ahead of the Artemis IV mission in 2028, the first lunar mission to include an orbiting space station.
“Gateway sounds so science fiction, but it’s real,” Dudley recently said. “And we’re building it. And in a few years, it’s going to be around the Moon and that’s when the real work, the fun work in my opinion, is going to begin and science will never be the same.”
Gateway is humanity’s first lunar space station as a central component of the Artemis campaign that will return humans to the Moon for scientific discovery and chart a path for the first human missions to Mars.

Teams from NASA and ESA (European Space Agency), including NASA astronaut Stan Love (far right) and ESA astronaut Luca Parmitano (far left) help conduct human factors testing inside a mockup for the Gateway lunar space station. Thales Alenia Space Teams at NASA, ESA (European Space Agency), and Thales Alenia Space, including astronauts Stan Love and Luca Parmitano, came together in Turin, Italy, this summer for a test run of Gateway, humanity’s first space station to orbit the Moon.
The group conducted what is known as human factors testing inside a mockup of Lunar I-Hab, one of four Gateway modules where astronauts will live, conduct science, and prepare for missions to the Moon’s South Pole region. The testing is an important step on the path to launch by helping refine the design of spacecraft for comfort and safety.
Lunar I-Hab is provided by ESA and Thales Alenia Space and is slated to launch on Artemis IV. During that mission, four astronauts will launch inside the Orion spacecraft atop an upgraded version of the SLS (Space Launch System) rocket and deliver Lunar I-Hab to Gateway in orbit around the Moon.
ESA, CSA (Canadian Space Agency), JAXA (Japan Aerospace Exploration Agency), and the Mohammad Bin Rashid Space Centre of the United Arab Emirates are providing major hardware for Gateway, including science experiments, the modules where astronauts will live and work, robotics, and life support systems.
International teams of astronauts will explore the scientific mysteries of deep space with Gateway as part of the Artemis campaign to return to the Moon for scientific discovery and chart a path for the first human missions to Mars and beyond.

4 Min Read NASA Terminal Transmits First Laser Communications Uplink to Space
NASA's LCOT (Low-Cost Optical Terminal) located at the agency's Goddard Space Flight Center in Greenbelt, Md. Credits: NASA NASA’s LCOT (Low-Cost Optical Terminal), a ground station made of modified commercial hardware, transmitted its first laser communications uplink to the TBIRD (TeraByte Infrared Delivery), a tissue box-sized payload formerly in low Earth orbit.
During the first live sky test, NASA’s LCOT produced enough uplink intensity for the TBIRD payload to identify the laser beacon, connect, and maintain a connection to the ground station for over three minutes. This successful test marks an important achievement for laser communications: connecting LCOT’s laser beacon from Earth to TBIRD required one milliradian of pointing accuracy, the equivalent of hitting a three-foot target from over eight American football fields away.
The test was one of many laser communications achievements TBIRD made possible during its successful, two-year mission. Prior to its mission completion on Sept. 15, 2024, the payload transmitted at a record-breaking 200 gigabits per second. In an actual use case, TBIRD’s three-minute connection time with LCOT would be sufficient to return over five terabytes of critical science data, the equivalent of over 2,500 hours of high-definition video in a single pass. As the LCOT sky test demonstrates, the ultra-high-speed capabilities of laser communications will allow science missions to maintain their connection to Earth as they travel farther than ever before.
Measurement data of the power, or “fluency,” of the connection between NASA’s LCOT (Low-Cost Optical Terminal) laser beacon and TBIRD’s (TeraByte Infrared Delivery) receiver provided by Massachusetts Institute of Technology Lincoln Laboratory (MIT-LL). LCOT and TBIRD maintained a sufficient connection for over three minutes — enough time for TBIRD to return over five terabytes of data. NASA/Dave Ryan NASA’s SCaN (Space Communications and Navigation) program office is implementing laser communications technology in various orbits, including the upcoming Artemis II mission, to demonstrate its potential impact in the agency’s mission to explore, innovate, and inspire discovery.
“Optical, or laser, communications can transfer 10 to 100 times more data than radio frequency waves,” said Kevin Coggins, deputy associate administrator and SCaN program manager. “Literally, it’s the wave of the future, as it’ll enable scientists to realize an ever-increasing amount of data from their missions and will serve as our critical lifeline for astronauts traveling to and from Mars.”

A recording of TBIRD’s (TeraByte Infrared Delivery) successful downlink from NASA’s LCOT (Low-Cost Optical Terminal) Wide Field Camera. The light saturation from the downlink caused a secondary reflection in the upper right of the video.NASA Historically, space missions have used radio frequencies to send data to and from space, but with science instruments capturing more data, communications assets must meet increasing demand. The infrared light used for laser communications transmits the data at a shorter wavelength than radio, meaning ground stations on Earth can send and receive more data per second.
The LCOT team continues to refine pointing capabilities through additional tests with NASA’s LCRD (Laser Communications Relay Demonstration). As LCOT and the agency’s other laser communications missions continue to reach new milestones in connectivity and accessibility, they demonstrate laser communications’ potential to revolutionize scientists’ access to new data about Earth, our solar system, and beyond.
“It’s a testament to the hard work and skill of the entire team,” said Dr. Haleh Safavi, project lead for LCOT. “We work with very complicated and sensitive transmission equipment that must be installed with incredible precision. These results required expeditious planning and execution at every level.”
NASA’s LCOT (Low-Cost Optical Terminal) at the agency’s Goddard Space Flight Center in Greenbelt, Maryland, uses slightly modified commercial hardware to reduce the expense of implementing laser communications technology. NASA Experiments like TBIRD and LCRD are only two of SCaN’s multiple in-space demonstrations of laser communications, but a robust laser communications network relies on easily reconfigurable ground stations on Earth. The LCOT ground station showcases how the government and aerospace industry can build and deploy flexible laser communications ground stations to meet the needs of a wide variety of NASA and commercial missions, and how these ground stations open new doors for communications technology and extremely high data volume transmission.
NASA’s LCOT is developed by the agency’s Goddard Space Flight Center in Greenbelt, Maryland. TBIRD was developed in partnership with the Massachusetts Institute of Technology Lincoln Laboratory (MIT-LL) in Lexington. TBIRD was flown and operated as a collaborative effort among NASA Goddard; NASA’s Ames Research Center in California’s Silicon Valley; NASA’s Jet Propulsion Laboratory in Southern California; MIT-LL; and Terran Orbital Corporation in Irvine, California. Funding and oversight for LCOT and other laser communications demonstrations comes from the (SCaN) Space Communications and Navigation program office within the Space Operations Mission Directorate at NASA Headquarters in Washington.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Gateway’s Habitation and Logistics Outpost stands vertically inside a Thales Alenia Space facility in Turin, Italy, after completing static load testing. Thales Alenia Space Major Gateway hardware recently crossed an important testing milestone on its path to launch to the Moon, where it will support new science and house astronauts in lunar orbit.
Gateway’s HALO (Habitation and Logistics Outpost) successfully completed static load testing, a rigorous stress test of how well the structure responds to the forces encountered in deep space. Thales Alenia Space, subcontractor to Northrop Grumman, conducted the testing in Turin, Italy. Static load testing is one of the major environmental stress tests HALO will undergo, and once all phases of testing are complete, the module will be ready to move from Italy to Gilbert, Arizona, where Northrop Grumman will complete final outfitting.
HALO is one of four pressurized Gateway modules where astronauts will live, conduct science, and prepare for missions to the lunar South Pole region. It will launch with Gateway’s Power and Propulsion Element on a SpaceX Falcon Heavy rocket to lunar orbit.
Gateway is humanity’s first lunar space station supporting a new era of exploration and scientific discovery as part of NASA’s Artemis campaign that will establish a sustained presence on and around the Moon, paving the way for the first crewed mission to Mars.
