The feat was part of a series of tests on new technology that could provide live video coverage of astronauts on the Moon during the Artemis missions.
Historically, NASA has relied on radio waves to send information to and from space. Laser communications use infrared light to transmit 10 to 100 times more data faster than radio frequency systems.

They then flew over Lake Erie sending data from the aircraft to an optical ground station in Cleveland. From there, it was sent over an Earth-based network to NASA’s White Sands Test Facility in Las Cruces, New Mexico, where scientists used infrared light signals to send the data.
The signals traveled 22,000 miles away from Earth to NASA’s Laser Communications Relay Demonstration (LCRD), an orbiting experimental platform. The LCRD then relayed the signals to the ILLUMA-T (Integrated LCRD LEO User Modem and Amplifier Terminal) payload mounted on the orbiting laboratory, which then sent data back to Earth. During the experiments, High-Rate Delay Tolerant Networking (HDTN), a new system developed at Glenn, helped the signal penetrate cloud coverage more effectively.

Aeronautics testing of space technology often finds issues more effectively than ground testing, while remaining more cost-effective than space testing. Proving success in a simulated space environment is key to moving new technology from a laboratory into the production phase.
“Teams at Glenn ensure new ideas are not stuck in a lab, but actually flown in the relevant environment to ensure this technology can be matured to improve the lives of all of us,” said James Demers, chief of aircraft operations at Glenn.
The flights were part of an agency initiative to stream high-bandwidth video and other data from deep space, enabling future human missions beyond low Earth orbit. As NASA continues to develop advanced science instruments to capture high-definition data on the Moon and beyond, the agency’s Space Communications and Navigation, or SCaN, program embraces laser communications to send large amounts of information back to Earth.
The optical system temporarily installed on the belly of the PC-12 aircraft has proven to be a very reliable high-performance system to communicate with prototype flight instrumentation and evaluate emerging technologies to enhance high-bandwidth systems.Credit: NASA/Sara Lowthian-Hanna While the ILLUMA-T payload is no longer installed on the space station, researchers will continue to test 4K video streaming capabilities from the PC-12 aircraft through the remainder of July, with the goal of developing the technologies needed to stream humanity’s return to the lunar surface through Artemis.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA astronaut Kate Rubins uses a hammer to get a drive tube into the ground to collect a pristine soil sample during a nighttime simulated moonwalk in the San Francisco Volcanic Field in Northern Arizona on May 16, 2024. Surviving and operating through the lunar night was identified as a top-ranked 2024 Civil Space Challenge, and tests such as these help NASA astronauts and engineers practice end-to-end lunar operations. NASA/Josh Valcarcel This spring, NASA published a document overviewing almost 200 technology areas requiring further development to meet future exploration, science, and other mission needs – and asked the aerospace community to rate their importance. The goal was to better integrate the community’s most pervasive technical challenges, or shortfalls, to help guide NASA’s space technology development and investments.
Today, NASA’s Space Technology Mission Directorate (STMD) released the 2024 Civil Space Shortfall Ranking document, integrating inputs from NASA mission directorates and centers, small and large industry organizations, government agencies, academia, and other interested individuals. STMD will use the inaugural list and annual updates as one of many factors to guide its technology development projects and investments.
“Identifying consensus among challenges across the aerospace industry will help us find solutions, together,” said NASA Associate Administrator Jim Free. “This is the groundwork for strengthening the nation’s technological capabilities to pave the way for new discoveries, economic opportunities, and scientific breakthroughs that benefit humanity.”
The integrated results show strong stakeholder agreement among the 30 most important shortfalls. At the top of the list is surviving and operating through the lunar night, when significant and sustained temperature drops make it difficult to run science experiments, rovers, habitats, and more. Solution technologies could include new power, thermal management, and motor systems. Second and third on the integrated list are the need for high-power energy generation on the Moon and Mars and high-performance spaceflight computing.
The inputs received are already igniting meaningful conversations to help us and our stakeholders make smarter decisions. We will refine the process and results annually to ensure we maintain a useful approach and tool that fosters resilience in our space technology endeavors.”
Michelle Munk
Acting Chief Architect for STMD
Highly rated capability areas in the top 20 included advanced habitation systems, autonomous systems and robotics, communications and navigation, power, avionics, and nuclear propulsion. Beyond the top quartile, stakeholder shortfall scores varied, likely aligning with their interests and expertise. With many shortfalls being interdependent, it emphasizes the need to make strategic investments across many areas to maintain U.S. leadership in space technology and drive economic growth.
STMD is evaluating its current technology development efforts against the integrated list to identify potential adjustments within its portfolio.
“This effort is an excellent example of our directorates working together to assess future architecture needs that will enable exploration and science for decades to come,” said Nujoud Merancy, deputy associate administrator for the Strategy and Architecture Office within NASA’s Exploration Systems Development Mission Directorate.
The 2024 results are based on 1,231 total responses, including 769 internal and 462 external responses. Twenty were consolidated responses, representing multiple individuals from the same organization. Once average shortfall scores were calculated for each organization, STMD grouped, totaled, and averaged scores for nine stakeholder groups and then applied pre-determined weights to each to create the overall ranking. In the document, NASA also published the ranked results for each stakeholder group based on the 2024 feedback.
The rankings are based on the numerical scores received and not responses to the open-ended questions. NASA anticipates the qualitative feedback will uncover additional insights and more.
NASA will host a webinar to overview the ranking process and results on July 26, 2024, at 2 p.m. EDT.
Register for the Stakeholder Webinar “Communicating our most pressing technology challenges is a great way to tap into the abilities across all communities to provide solutions to critical problems,” said Dr. Carolyn Mercer, chief technologist for NASA’s Science Mission Directorate.

NASA Astronaut Eileen Collins, STS-93 commander, looks through a checklist on the space shuttle Columbia’s middeck in this July 1999 image. Collins was the first female shuttle commander.
Collins graduated in 1979 from Air Force Undergraduate Pilot Training at Vance AFB, Oklahoma, where she was a T-38 instructor pilot until 1982. She continued her career as an instructor pilot of different aircraft until 1989. She was selected for the astronaut program while attending the Air Force Test Pilot School at Edwards AFB, California, which she graduated from in 1990. Collins became an astronaut in 1991 and over the course of four spaceflights, logged over 872 hours in space. She retired from NASA in May 2006.

5 Min Read Eileen Collins Broke Barriers as America’s First Female Space Shuttle Commander
Astronauts Eileen M. Collins, mission commander and Jeffrey S. Ashby, pilot, peruse checklists on Columbia's middeck during the STS-93 mission. Credits: NASA At the end of February 1998, Johnson Space Center Deputy Director James D. Wetherbee called Astronaut Eileen Collins to his office in Building 1. He told her she had been assigned to command STS-93 and went with her to speak with Center Director George W.S. Abbey who informed her that she would be going to the White House the following week.
Selecting a female commander to fly in space was a monumental decision, something the space agency recognized when they alerted the president of the United States. First Lady Hillary Clinton wanted to publicly announce the flight to the American people along with her husband President William J. Clinton and NASA Administrator Daniel S. Goldin.
President William Jefferson Clinton and First Lady Hillary Rodham Clinton with Eileen Collins in the Oval Office.Sharon Farmer and White House Photograph Office At that event, on March 5, 1998, the First Lady noted what a change it would be to have a female in the commander’s seat. Referencing Neil A. Armstrong’s first words on the Moon, Clinton proclaimed, “Collins will take one big step forward for women and one giant leap for humanity.” Collins, a military test pilot and shuttle astronaut, was about to break one of the last remaining barriers for women at NASA by being assigned a position previously filled by men only. Clinton went on to reflect on her own experience with the space agency when she explained how in 1962, at the age of 14, she had written to NASA and asked about the qualifications to become an astronaut. NASA responded that women were not being considered to fly space missions. “Well, times have certainly changed,” she said wryly.
Eileen Collins’ assignment as the first female shuttle commander was front page news in the March 13, 1998 issue of Johnson Space Center’s Space News Roundup.NASA The same year Hillary Clinton inquired about the astronaut corps, a special subcommittee of the U.S. House of Representatives Committee on Science and Astronautics held hearings on the issue of sexual discrimination in the selection of astronauts. Astronaut John H. Glenn, who had flown that February in 1962, justified women’s exclusion from the corps. “I think this gets back to the way our social order is organized really. It is just a fact. The men go off and fight the wars and fly the airplanes and come back and help design and build and test them. The fact that women are not in this field is a fact of our social order. It may be undesirable.” Attitudes about women’s place in society, not just at NASA, were stubbornly hard to break. It would be 16 years before the agency selected its first class of astronauts that included women.
Astronaut Eileen M. Collins looks over a checklist at the commander’s station on the forward flight deck of the space shuttle Columbia on July 23, 1999, the first day of the mission. The most important event of this day was the deployment of the Chandra X-Ray Observatory.NASA By 1998, views about women’s roles had changed substantially, as demonstrated by the naming of the first female shuttle commander. The agency even commissioned a song for the occasion: “Beyond the Sky,” by singer-songwriter Judy Collins. NASA dedicated the historic mission’s launch to America’s female aviation pioneers from the Ninety-Nines—an international organization of women pilots—to the Women Airforce Service Pilots (WASPs), women who ferried aircraft for the military during World War II. Collins also extended an invitation to the women who had participated in Randy Lovelace’s Woman in Space Program, where women went through the same medical and psychological tests as the Mercury 7 astronauts; the press commonly refers to these women as the Mercury 13. (Commander Collins had thanked both the WASPs and the Mercury 13 for paving the way and inspiring her career in aviation and spaceflight in her White House speech.)
In a way, it's like my dream come true.
Betty Skelton Frankman
Pioneering Woman Aviator
In a group interview with several of the WASPs in Florida, just before launch, Mary Anna “Marty” Martin Wyall explained why they came. “Eileen Collins was one of those women that has always looked at us as being her mentors, and we just think she’s great. That’s why we want to come see her blast off.” Betty Skelton Frankman expressed just how proud she was of Collins, and how NASA’s first female commander would be fulfilling her dream to fly in space. “In a way,” she said, “it’s like my dream come true.” In the ‘60s it was not possible for a woman to fly in space because none met the requirements as laid out by NASA. But by the end of the twentieth century, women had been in the Astronaut Office for 20 years, and opportunities for women had grown as women were selected as pilot astronauts. NASA named its second and only other female space shuttle commander, Pamela A. Melroy, to STS-120, and Peggy A. Whitson went on to command the International Space Station. Melroy and Whitson shook hands in space, when their missions coincided, for another historic first—two women commanding space missions at the same time.
Twenty-five years ago, Eileen Collins’ command broke down barriers in human spaceflight. As the First Lady predicted, her selection led to other opportunities for women astronauts. More women continue to command spaceflight missions, including Expedition 65 Commander Shannon Walker and Expedition 68 Commander Samantha Cristoforetti. More importantly, Collins became a role model for young people interested in aviation, engineering, math, science, and technology. Her career demonstrated that there were no limits if you worked hard and pursued your passion.

Science Activation’s PLACES Team Facilitates Second Professional Learning Institute
The NASA Science Activation Program’s Place-Based Learning to Advance Connections, Education, and Stewardship (PLACES) team successfully led their second Professional Learning (PL) Summer Institute (SI) at Northern Arizona University (NAU) in Flagstaff, Arizona from June 11-13, 2024. The team led a group of 13 educators through a variety of powerful place-based data-rich (PBDR) experiences across the three-day SI. PL kicked off with teachers engaging in an intensive field experience at Hat Ranch that leveraged the ecological expertise of NAU’s subject matter expert, Jared Litson Begay, and using data collection protocols from the NASA-sponsored program, GLOBE (Global Learning and Observations to Benefit the Environment) to better understand piñon pine populations in Flagstaff ecosystems. Following this, teachers moved from their primary data collection experiences to exploring secondary data that expanded on the piñon pine focus by leveraging data and the Data Literacy Cubes from My NASA Data (MND).
Using and reflecting on GLOBE protocols created powerful conversations where teachers saw how place influenced how they engaged in data collection and how data can help develop new place-based knowledge and connections in their contexts. One teacher even shared that “collecting data using the GLOBE app and making observations about data helped me better understand how I can use these practices with my students.” The MND data and Data Literacy Cubes offered educators the pathways to move from their primary data collection experiences to ask and answer new and exciting questions.
In the follow-up survey, teachers shared that they are interested in exploring “additional resources from NASA,” using “local experts or data for small town/rural areas through NASA,” and implementing PBDR instruction using NASA assets in the coming months. 100% of teachers who were surveyed after the PL indicated (1) they agree or strongly agree that they feel greater connection to NASA and knowledge of NASA assets, and (2) they would recommend the PLACES PL to a colleague. In the coming months, the teachers will participate in a virtual Community of Practice where they will implement PBDR experiences in their own contexts, share examples of student work, and elicit feedback from one another to continue improving their practice.
The PLACES team would like to give a huge shout-out to those who contributed to planning, developing, and implementing the NAU Summer Institute!
