Engineering teams with NASA and Boeing recently completed ground hot fire testing of a Starliner reaction control system thruster at White Sands Test Facility in New Mexico. The test series involved firing the engine through similar in-flight conditions the spacecraft experienced during its approach to the space station, as well as various stress-case firings for what is expected during Starliner’s undocking and the deorbit burn that will position the spacecraft for a landing in the southwestern United States. Teams are analyzing the data from these tests, and leadership plans to discuss initial findings during the briefing.
NASA astronauts Butch Wilmore and Suni Williams arrived at the orbiting laboratory on June 6, after lifting off aboard a United Launch Alliance Atlas V rocket from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida on June 5. Since their arrival, the duo has been integrated with the Expedition 71 crew, performing scientific research and maintenance activities as needed.
As part of NASA’s Commercial Crew Program, the mission is an end-to-end test of the Starliner system. Following a successful return to Earth, NASA will begin the process of certifying Starliner for rotational missions to the International Space Station. Through partnership with American private industry, NASA is opening access to low Earth orbit and the space station to more people, science, and commercial opportunities.

ICON, shown in this artist’s concept, studied the frontiers of space, the dynamic zone high in our atmosphere where terrestrial weather from below meets space weather above. NASA/Goddard/Conceptual Image Lab NASA’s ICON mission studied the outermost layer of Earth’s atmosphere called the ionosphere. ICON provided critical insights into interplay between space weather and Earth’s weather. The mission gathered unprecedented detail of airglow, showed a relationship between the atmosphere’s ions and Earth’s magnetic field lines, and provided the first concrete observation to confirm Earth’s long-theorized ionospheric dynamo. Nearly a year after ICON accomplished its primary mission, communication was lost in November 2022 for unclear reasons. NASA formally concluded the mission after several months of troubleshooting could not regain contact. After contributing to many important findings on the boundary between Earth’s atmosphere and space, the Ionospheric Connection Explorer (ICON) mission has come to an end. ICON launched in October 2019 and after completing its two-year mission objectives in December 2021, it operated as an extended mission for another year.
“The ICON mission has truly lived up to its name,” said Joseph Westlake, heliophysics division director at NASA Headquarters in Washington. “ICON not only successfully completed and exceeded its primary mission objectives, it also provided critical insights into the ionosphere and the interplay between space and terrestrial weather.”
The ICON spacecraft studied a part of our planet’s outermost layer of the atmosphere, called the ionosphere. From there, ICON investigated what events impact the ionosphere, including Earth’s weather from below and space weather from above.
The ionosphere is the lowest boundary of space, located between 55 miles to 360 miles above Earth’s surface. It is made up of a sea of particles that have been ionized, a mix of positively charged ions and negatively charged electrons called plasma. This frontier of space is a dynamic and busy region, home to many satellites — including the International Space Station — and is a conduit for radio communications and GPS signals.

NASA/Goddard/Conceptual Image Lab/Krystofer Kim Both satellites and signals can be disrupted by the complex interactions of terrestrial and space weather. Studying and understanding the ionosphere is crucial to understanding space weather and its effects on our technology.
The ICON mission captured unprecedented data about the ionosphere with direct measurements of the charged gas in its immediate surroundings alongside images of one of the ionosphere’s most stunning features — airglow.
ICON tracked the colorful bands as they moved through the ionosphere. Airglow is created by a process similar to what creates the aurora. However, airglow occurs around the world, not just the northern and southern latitudes where auroras are typically found. Although airglow is normally dim, ICON’s instruments were specially designed to capture even the faintest glow to build a picture of the ionosphere’s density, composition, and structure.
The lowest reaches of space glow with bright bands of color called airglow. NASA Through the principle of Doppler shift, ICON’s sensitive imagers also detected the motion of the atmosphere as it glowed. “It’s like measuring a train’s speed by detecting the change in the pitch of its horn — but with light,” said Thomas J. Immel, ICON mission lead at the University of California, Berkeley. The mission was specifically designed to perform this technically difficult measurement.
A New Ionospheric Perspective
The ICON mission’s comprehensive view of the upper atmosphere provided valuable data for scientists to unravel for years to come. For instance, its measurements showed how the 2022 Hunga Tonga-Hunga Ha’apai volcanic eruption disrupted electrical currents in the ionosphere.
“ICON was able to capture the speed of the volcanic eruption, allowing us to directly see how it affected the motion of charged particles in the ionosphere,” Immel said. “This was a clear example of the connection between tropical weather and ionospheric structure. ICON showed us how things that happen in terrestrial weather have a direct correlation with events in space.”
Another scientific breakthrough was ICON’s measurements of the motion of ions in the atmosphere and their relationship with Earth’s magnetic field lines. “It was truly unique,” Immel remarked. “ICON’s measurements of the motion of ions in the atmosphere was scientifically transformational in our understanding of behavior in the ionosphere.”

When the wind changes direction, the ion fluctuation changes to flow downward.NASA’s Scientific Visualization Studio/William T. Bridgman With ICON’s help, scientists better understand how these interactions drive a process called the ionospheric dynamo. The dynamo, which lies at the bottom of the ionosphere, remained a mystery for decades because it is difficult to observe.
ICON provided the first concrete observation of winds fueling the dynamo and how this influences space weather. Unpredictable terrestrial winds move plasma around the ionosphere, sending the charged particles shooting out into space or plummeting toward Earth. This electrically charged tug-of-war between the ionosphere and Earth’s electromagnetic fields acts as a generator, creating complex electric and magnetic fields that can affect both technology and the ionosphere itself.
“No one had ever seen this before,” Immel said. “ICON finally and conclusively provided experimental confirmation of the wind dynamo theory.”
An Iconic Legacy
On Nov. 25, 2022, the ICON team lost contact with the spacecraft. Communication with the spacecraft could not be established, even after performing a power cycle reset using a built-in command loss timer. Though the spacecraft remains intact, other troubleshooting techniques were unable to re-establish contact between the ICON spacecraft and mission operators.
“ICON’s legacy will live on through the breakthrough knowledge it provided while it was active and the vast dataset from its observations that will continue to yield new science,” Westlake said. “ICON serves as a foundation for new missions to come.”

Preparations for Next Moonwalk Simulations Underway (and Underwater)
A graphic representation of a laser communications relay between the International Space Station, the Laser Communications Relay Demonstration spacecraft, and the Earth.Credit: NASA/Dave Ryan A team at NASA’s Glenn Research Center in Cleveland streamed 4K video footage from an aircraft to the International Space Station and back for the first time using optical, or laser, communications. 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.
From left to right, Kurt Blankenship, research aircraft pilot, Adam Wroblewski, instrument operator, and Shaun McKeehan, High-Rate Delay Tolerant Networking software developer, wait outside the PC-12 aircraft, preparing to take flight. Credit: NASA/Sara Lowthian-Hanna Working with the Air Force Research Laboratory and NASA’s Small Business Innovation Research program, Glenn engineers temporarily installed a portable laser terminal on the belly of a Pilatus PC-12 aircraft. 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.

Mechanical Engineer Jeff Pollack finalizes his design for the integration of the laser communications terminal into the PC-12 research aircraft.Credit: NASA/Sara Lowthian-Hanna After each flight test, the team continuously improved the functionality of their technology. 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.
