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.”

NASA and its international partners are sending scientific investigations to the International Space Station on Northrop Grumman’s 21st commercial resupply services mission. Flying aboard the company’s Cygnus spacecraft are tests of water recovery technology and a process to produce stem cells in microgravity, studies of the effects of spaceflight on microorganism DNA and liver tissue growth, and live science demonstrations for students. The mission is scheduled to launch from Cape Canaveral Space Force Station in Florida by early August.
Read more about some of the research making the journey to the orbiting laboratory:
Testing materials for packed systems
Packed bed reactors are systems that use materials such as pellets or beads “packed” inside a structure to increase contact between different phases of fluids, such as liquid and gas. These reactors are used for various applications including water recovery, thermal management, and fuel cells. Scientists previously tested the performance in space of glass beads, Teflon beads, a platinum catalyst, and other packing materials. Packed Bed Reactor Experiment: Water Recovery Series evaluates gravity’s effects on eight additional test articles.
Results could help optimize the design and operation of packed bed reactors for water filtration and other systems in microgravity and on the Moon and Mars. Insights from the investigation also could lead to improvements in this technology for applications on Earth such as water purification and heating and cooling systems.

STEMonstrations Screaming Balloon uses a balloon, a penny, and a hexagonal nut (the kind used to secure a bolt) for a NASA STEMonstration performed and recorded by astronauts on the space station. The penny and the nut are whirled separately inside an inflated balloon to compare the sounds they make. Each STEMonstration illustrates a different scientific concept, such as centripetal force, and includes resources to help teachers further explore the topics with their students.
NASA astronauts Matthew Dominick and Jeanette Epps prepare for a STEMonstration on the International Space Station.NASA More, better stem cells
In-Space Expansion of Hematopoietic Stem Cells for Clinical Application (InSPA-StemCellEX-H1) continues testing a technology to produce human hematopoietic stem cells (HSCs) in space. HSCs give rise to blood and immune cells and are used in therapies for patients with certain blood diseases, autoimmune disorders, and cancers.
The investigation uses a system called BioServe In-space Cell Expansion Platform, or BICEP, which is designed to expand HSCs three hundredfold without the need to change or add new growth media, according to Louis Stodieck, principal investigator at the University of Colorado Boulder. “BICEP affords a streamlined operation to harvest and cryopreserve cells for return to Earth and delivery to a designated medical provider and patient,” said Stodieck.
Someone in the United States is diagnosed with a blood cancer such as leukemia about every three minutes. Treating these patients with transplanted stem cells requires a donor-recipient match and long-term repopulation of transplanted stem cells. This investigation demonstrates whether expanding stem cells in microgravity could generate far more continuously renewing stem cells.
“Our work eventually could lead to large-scale production facilities, with donor cells launched into orbit and cellular therapies returned to Earth,” said Stodieck.
NASA astronaut Frank Rubio works on the first test of methods for expanding stem cells in space, StemCellEX-H Pathfinder. The InSPA-StemCellEX-H1 investigation continues this work.NASA DNA repair in space
Rotifer-B2, an ESA (European Space Agency) investigation, explores how spaceflight affects DNA repair mechanisms in a microscopic bdelloid rotifer, Adineta vaga. These tiny but complex organisms are known for their ability to withstand harsh conditions, including radiation doses 100 times higher than human cells can survive. The organisms are dried, exposed to high radiation levels on Earth, and rehydrated and cultured in an incubator on the station.
“Previous research indicates that rotifers repair their DNA in space with the same efficiency as on Earth, but that research provided only genetic data,” said Boris Hespeels, co-investigator, of Belgium’s Laboratory of Evolutionary Genetics and Ecology. “This experiment will provide the first visual proof of survival and reproduction during spaceflight,” said Hespeels
Results could provide insights into how spaceflight affects the rotifer’s ability to repair sections of damaged DNA in a microgravity environment, and could improve the general understanding of DNA damage and repair mechanisms for applications on Earth.

Maturation of Vascularized Liver Tissue Construct studies the development in space of bioprinted liver tissue constructs that contain blood vessels. Constructs are tissue samples grown outside the body using bioengineering techniques. Scientists expect the microgravity environment to allow improved cellular distribution throughout tissue constructs.
“We are especially keen on accelerating the development of vascular networks,” said James Yoo, principal investigator, at the Wake Forest Institute of Regenerative Medicine. “The experimental data from microgravity will provide valuable insights that could enhance the biomanufacturing of vascularized tissues to serve as building blocks to engineer functional organs for transplantation.”

Image C shows the tissue construct connected to a perfusion system, a pump that moves fluid through it.Wake Forest Institute for Regenerative Medicine. This mission also delivers plants for the APEX-09 investigation, which examines plant responses to stressful environments and could inform the design of bio-regenerative support systems on future space missions.

The latest crew chosen by NASA to venture on a simulated trip to Mars inside the agency’s Human Exploration Research Analog. From left are Sergii Iakymov, Erin Anderson, Brandon Kent, and Sarah Elizabeth McCandless.Credit: C7M3 Crew NASA selected a new team of four research volunteers to participate in a simulated mission to Mars within HERA (Human Exploration Research Analog) at the agency’s Johnson Space Center in Houston.
Erin Anderson, Sergii Iakymov, Brandon Kent, and Sarah Elizabeth McCandless will begin their simulated trek to Mars on Friday, Aug. 9. The volunteer crew members will stay inside the 650-square-foot habitat for 45 days, exiting Monday, Sept. 23 after a simulated “return” to Earth. Jason Staggs and Anderson Wilder will serve as alternate crew members.
The HERA missions offer scientific insights into how people react to the type of isolation, confinement, work and life demands, and remote conditions astronauts might experience during deep space missions.
The facility supports more frequent, shorter-duration simulations in the same building as CHAPEA (Crew Health and Performance Analog). This crew is the third group of volunteers to participate in a simulated Mars mission in HERA this year. The most recent crew completed its HERA mission on June 24. In total, there will be four analog missions in this series.
During this summer’s simulation, participants will perform a mix of science and operational tasks, including harvesting plants from a hydroponic garden, growing shrimp, deploying a small, cube-shaped satellite (CubeSat) to simulate gathering virtual data for analysis, “walking” on the surface of Mars using virtual reality goggles, and flying simulated drones on the simulated Mars surface. The team members also will encounter increasingly longer communication delays with Mission Control throughout their mission, culminating in five-minute lags as they “near” Mars. Astronauts traveling to Mars may experience communications delays of up to 20 minutes.
NASA’s Human Research Program will conduct 18 human health experiments during each of the 2024 HERA missions. Collectively, the studies explore how a Mars-like journey may affect the crew members’ mental and physical health. The work also will allow scientists to test certain procedures and equipment designed to keep astronauts safe and healthy on deep space missions.
