You’d think a NASA aerospace engineer who spends her days inside a giant dome researching how to make plane engines quieter and spacecraft systems more efficient would have a pretty booked schedule. Still, advocacy and mentoring, especially for women and girls in STEM, is something Danielle Koch always tries to say yes to.
For decades, Koch has tutored students, volunteered as a mentor for engineering challenges, and engaged Pre-K through Ph.D. classes with stories from her career at NASA’s Glenn Research Center in Cleveland. Koch also works to recruit women and others from underrepresented groups to the field and find ways to remove barriers to their advancement.
For her efforts, Koch was recently recognized by the Girl Scouts of North East Ohio as a 2024 Woman of Distinction. The award, presented to Koch during a ceremony on May 16, celebrates women whose leadership contributes to the community, providing girls with positive role models. Koch says that diverse people and programs have similarly shaped her own career path.
“None of this is anything I’ve done myself; there are huge groups of people who are making change and making things better for all of us,” Koch said. “Every story I tell about me being a woman at NASA is really a story about them.”

A Pittsburgh native and graduate of Case Western Reserve University, Koch began her career as a test engineer at NASA Glenn in 1990 as the only woman in her work group. While there were women around her, Koch says she did not see many senior-level female engineers or scientists “working ahead of her.” With determination and the “rock-solid” support of colleagues, family, and friends, Koch forged ahead, becoming a research aerospace engineer in NASA Glenn’s Acoustics Branch in 1998.
“She’s somebody that goes above and beyond almost all of the time, while using her knowledge and career to bring others up to her level,” said John Lucero, Koch’s supervisor and the chief of the Acoustics Branch at NASA Glenn.
Koch realized the landscape around her was evolving in 2016 when she sat down in one of NASA Glenn’s biggest conference rooms for the center’s annual Women Ignite workshop. It was the first time she’d seen the space entirely filled with women.
“It was striking,” Koch said. “Learning from each other and being visible to each other, it’s so huge.”
Koch points to insights gleaned from these workshops — which are focused on networking, skill-building, and empowerment — as propelling her forward, along with the center’s Women in STEM Leadership Development Program, launched to help the women of NASA Glenn connect and grow as leaders.

Koch also spotlights the value of the Women at Glenn employee resource group, which organizes events and panels, shares job and volunteer opportunities, and provides a platform for addressing issues in the workplace.
“The employee resource group offers a great sense of community for women at the center,” said Women at Glenn co-chair and aerospace engineer Christine Pastor-Barsi. “When you feel like you’re unique, it’s good to know that there are others out there like you, even if you don’t always see them in the room.”
Koch says she’ll continue working as a mentor in the community and advocating for the diverse range of people who choose to take the leap into the STEM fields.
“It’s difficult to be the only one that’s visibly different in a room; it changes the way you communicate, the way you’re perceived,” Koch said. “It’s really important to reach out to people who are different from us and invite them to consider engineering as a career. We all benefit when we work with someone who’s different from ourselves.”

NASA’s Chandra Peers Into Densest and Weirdest Stars
The supernova remnant 3C 58 contains a spinning neutron star, known as PSR J0205+6449, at its center. Astronomers studied this neutron star and others like it to probe the nature of matter inside these very dense objects. A new study, made using NASA’s Chandra X-ray Observatory and ESA’s XMM-Newton, reveals that the interiors of neutron stars may contain a type of ultra-dense matter not found anywhere else in the Universe.
In this image of 3C 58, low-energy X-rays are colored red, medium-energy X-rays are green, and the high-energy band of X-rays is shown in blue. The X-ray data have been combined with an optical image in yellow from the Digitized Sky Survey. The Chandra data show that the rapidly rotating neutron star (also known as a “pulsar”) at the center is surrounded by a torus of X-ray emission and a jet that extends for several light-years. The optical data shows stars in the field.
The team in this new study analyzed previously released data from neutron stars to determine the so-called equation of state. This refers to the basic properties of the neutron stars including the pressures and temperatures in different parts of their interiors.
The authors used machine learning, a type of artificial intelligence, to compare the data to different equations of state. Their results imply that a significant fraction of the equations of state — the ones that do not include the capability for rapid cooling at higher masses — can be ruled out.
The researchers capitalized on some neutron stars in the study being located in supernova remnants, including 3C 58. Since astronomers have age estimates of the supernova remnants, they also have the ages of the neutron stars that were created during the explosions that created both the remnants and the neutron stars. The astronomers found that the neutron star in 3C 58 and two others were much cooler than the rest of the neutron stars in the study.
The team thinks that part of the explanation for the rapid cooling is that these neutron stars are more massive than most of the rest. Because more massive neutron stars have more particles, special processes that cause neutron stars to cool more rapidly might be triggered.
One possibility for what is inside these neutron stars is a type of radioactive decay near their centers where neutrinos — low mass particles that easily travel through matter — carry away much of the energy and heat, causing rapid cooling.
Another possibility is that there are types of exotic matter found in the centers of these more rapidly cooling neutron stars.
The Nature Astronomy paper describing these results is available here. The authors of the paper are Alessio Marino (Institute of Space Sciences (ICE) in Barcelona, Spain), Clara Dehman (ICE), Konstantinos Kovlakas (ICE), Nanda Rea (ICE), J. A. Pons (University of Alicante in Spain), and Daniele Viganò (ICE).

Visual DescriptionThis is an image of the leftovers from an exploded star called 3C 58, shown in X-ray and optical light. At the center of the remnant is a rapidly spinning neutron star, called a pulsar, that presents itself as a bright white object that’s somewhat elongated in shape.
Loops and swirls of material, in shades of blue and purple, extend outward from the neutron star in many directions, resembling the shape of an octopus and its arms.
Surrounding the octopus-like structure is a cloud of material in shades of red that is wider horizontally than it is vertically. A ribbon of purple material extends to the left edge of the red cloud, curling upward at its conclusion. Another purple ribbon extends to the right edge of the red cloud, though it is less defined than the one on the other side. Stars of many shapes and sizes dot the entire image.

Next Generation NASA Technologies Tested in Flight
Teams of NASA researchers put their next-generation technologies to the microgravity test in a series of parabolic flights that aim to advance innovations supporting the agency’s space exploration goals.
These parabolic flights provide a gateway to weightlessness, allowing research teams to interact with their hardware in reduced gravity conditions for intervals of approximately 22 seconds. The flights, which ran from February to April, took place aboard Zero Gravity Corporation’s G-FORCE ONE aircraft and helped to advance several promising space technologies.
Under the Fundamental Regolith Properties, Handling, and Water Capture (FLEET) project, researchers tested an ultrasonic blade technology in a regolith simulant at lunar and Martian gravities. On Earth, vibratory tools reduce the forces between the tool and the soil, which also lowers the reaction forces experienced by the system. Such reductions indicate the potential for mass savings for tool systems used in space.
This flight test aims to establish the magnitude of force reduction achieved by an ultrasonic tool on the Moon and Mars. Regolith interaction, including excavation, will be important to NASA’s resources to support long-duration lunar and Martian missions.
This experiment represents the success of an international effort three years in the making between NASA and Concordia University in Montreal, Quebec.Erin Rezich

“This experiment represents the success of an international effort three years in the making between NASA and Concordia University in Montreal, Quebec. It was a NASA bucket list item for me to conduct a parabolic flight experiment, and it was even more special to do it for my doctoral thesis work. I’m very proud of my team and everyone’s effort to make this a reality,” said Erin Rezich, project principal investigator at NASA’s Glenn Research Center in Cleveland, Ohio.
The FLEET project also has a separate payload planned for a future flight test on a suborbital rocket. The Vibratory Lunar Regolith Conveyor will demonstrate a granular material (regolith) transport system to study the vertical transport of lunar regolith simulants (soil) in a vacuum under a reduced gravity environment.
These two FLEET payloads increase the understanding of excavation behavior and how the excavated soil will be transported in a reduced gravity environment.

Under the agency’s On-Demand Manufacturing of Electronics (ODME) project, researchers tested 3D printing technologies to ease the use of electronics and tools aboard the International Space Station.
Flying its first microgravity environment test, the ODME Advanced Toolplate team evaluated a new set of substantially smaller 3D printed tools that provide more capabilities and reduce tool changeouts. The toolplate offers eight swappable toolheads so that new technologies can be integrated after it is sent up to the space station. The 3D printer component enables in-space manufacturing of electronics and sensors for structural and crew-monitoring systems and multi-material 3D printing of metals.
“The development of these critical 3D printing technologies for microelectronics and semiconductors will advance the technology readiness of these processes and reduce the risk for planned future orbital demonstrations on the International Space Station.curtis hill

Studying the Sun

Preparations for Next Moonwalk Simulations Underway (and Underwater) Science in Space: June 2024The Sun wields a huge influence on Earth. Its gravity holds our planet in its orbit, and solar energy drives the seasons, ocean currents, weather, climate, radiation belts, and auroras on Earth.
The solar wind, a flow of charged particles from the Sun, constantly bombards Earth’s magnetosphere, a vast magnetic shield around the planet. The Sun occasionally releases massive amounts of energy, creating solar geomagnetic storms that can interfere with communications and navigation and disrupt the electric power grid.
The colorful aurora borealis or Northern Lights and aurora australis or Southern Lights are created by the transfer of energy from solar electrons to molecules in Earth’s upper atmosphere. Those molecules then release that energy in the form of light. Different molecules create specific colors, such as green from oxygen.
Because Earth’s magnetic field directs solar electrons toward the poles, auroras typically are visible only at high latitudes, such as in Canada in the north and Australia in the south. But solar storms can send the lights into much lower latitudes. During a series of large solar eruptions in May 2024, for example, the display could be seen as far south as Texas and California.
Satellites captured auroras visible across the globe on May 11, 2024.NOAA
NASA has multiple missions studying how the Sun and solar storms affect Earth and space travel. The International Space Station contributes to this research in several ways.
Improved Solar Energy MeasurementsThe station’s Total and Spectral Solar Irradiance Sensor (TSIS) measures solar irradiance, the solar energy Earth receives, and solar spectral irradiance, a measure of the Sun’s energy in individual wavelengths. Knowing the magnitude and variability of solar irradiance improves understanding of Earth’s climate, atmosphere, and oceans and enables more accurate predictions of space weather. Better predictions could in turn help protect humans and satellites in space and electric power transmission and radio communications on the ground.
The first five years of TSIS observations demonstrated improved long-term spectral readings and lower uncertainties than measurements from a previous NASA mission, the Solar Radiation and Climate satellite. The accuracy of TSIS observations could improve models of solar irradiance variability and contribute to a long-term record of solar irradiance data.
Earlier Sun Monitoring Installation of the Solar instruments on the space station during a spacewalk.NASA
The ESA (European Space Agency) Sun Monitoring on the External Payload Facility of Columbus, or Solar, collected data on solar energy output for more than a decade with three instruments covering most wavelengths of the electromagnetic spectrum. Different wavelengths emitted by the Sun are absorbed by and influence Earth’s atmosphere and contribute to our climate and weather. This monitoring helps scientists see how solar irradiance affects Earth and provides data to create models for predicting its influence.
One instrument, the Solar Variable and Irradiance Monitor, covered the near-ultraviolet, visible, and thermal parts of the spectrum and helped improve the accuracy of these measurements.
The SOLar SPECtral Irradiance Measurement instrument covered higher ranges of the solar spectrum. Its observations highlighted significant differences from previous solar reference spectra and models. Researchers also reported that repeated observations made it possible to determine a reference spectrum for the first year of the SOLAR mission, which corresponded to a solar minimum prior to Solar Cycle 24.
Solar activity rises and falls over roughly 11-year cycles. The current Solar Cycle 25 began in December 2019, and scientists predicted a peak in solar activity between January and October of 2024, which included the May storms.
The third instrument, SOLar Auto-Calibrating EUV/UV Spectrometers, measured the part of the solar spectrum between extreme ultraviolet and ultraviolet. Most of this highly energetic radiation is absorbed by the upper atmosphere, making it impossible to measure from the ground. Results suggested that these instruments could overcome the problem of degrading sensitivity seen with other solar measuring devices and provide more efficient data collection.
Auroras from Space An aurora borealis display photographed from the International Space Station.NASA
Astronauts occasionally photograph the aurora borealis from the space station and post these images.
For the CSA (Canadian Space Agency) AuroraMAX project, crew members photographed the aurora borealis over Yellowknife, Canada, between fall 2011 and late spring 2012. The space images, coordinated with a network of ground-based observatories across Canada, contributed to an interactive display at an art and science festival to inspire public interest in how solar activity affects Earth. The project also provides a live feed of the aurora borealis online every September through April.
Student Satellites Deployment of the Miniature X-ray Solar Spectrometer and other CubeSats from the space station.NASA
The Miniature X-ray Solar Spectrometer CubeSat measured variation in solar X-ray activity to help scientists understand how it affects Earth’s upper atmosphere. Solar X-ray activity is enhanced during solar flares. Students at the University of Colorado Laboratory for Atmospheric Space Physics built the satellite, which deployed from the space station in early 2016.
Better data help scientists understand how solar events affect satellites, crewed missions, and infrastructure in space and on the ground. Ongoing efforts to measure how Earth’s atmosphere responds to solar storms are an important part of NASA’s plans for Artemis missions to the Moon and for later missions to Mars.

Summer solstice 2024
Summer officially begins in the Northern Hemisphere today 20 June, marking the longest day of the year. The summer solstice, which is when the Sun reaches the most northerly point in the sky, is set to occur tonight at 21:50 BST/22:50 CEST.
During the summer solstice, the Northern Hemisphere will experience the longest period of sunlight in a day or the longest day of the year. This is because of Earth’s position in orbit around the Sun and the way the North Pole is tilted towards the Sun during the solstice.
The Sun’s rays hit the Northern Hemisphere at their most direct angle, resulting in the most extended period of daylight. Despite the long hours of daylight, it may not necessarily be the hottest day of the year.
This animation shows one image per day captured by the Meteosat Second Generation from 20 June 2023 until 19 June 2024 captured at approximately 16:30 BST/17:30 CEST.

Webb snaps first image of aligned jets from newborn stars
For the first time, a phenomenon astronomers have long hoped to image directly has been captured by the NASA/ESA/CSA James Webb Space Telescope’s Near-InfraRed Camera (NIRCam). In this stunning image of the Serpens Nebula, the discovery lies in the northern area of this young, nearby star-forming region.
Stephanie Duchesne: Leading with Integrity and Openness for CLDP
Of all the lessons learned throughout her NASA career, the importance of relationship and personal integrity is one that has been repeatedly reinforced for Stephanie Duchesne, a Commercial Low Earth Orbit Development Program (CLDP) project executive.
“Each person you work with has their own unique perspectives and concerns, and in order to solve a problem or resolve a conflict, it is critical that you try and understand where they are coming from and build trust that you will do what you say,” she said. “That has been true at all levels of my career. I’ve learned that I never had to be the smartest person in the room to be able to help bring out the best ideas of the team, ask the right questions, and come up with effective and efficient solutions – that it is the collective mind and cohesion of the team that really creates the best solutions.”

Based at NASA’s Johnson Space Center in Houston, Duchesne has been part of CLDP since 2021, but her NASA career spans more than 20 years. She started in 2003 as a contractor for KBR Wyle Services, supporting the International Space Station Program as a biomedical engineering flight controller. She worked with the flight control and medical teams to address real-time anomalies and support crewmembers through key milestones and also spent seven months in Germany to help the ESA (European Space Agency) establish its own biomedical engineering flight controller program.
Duchesne then moved to the Environmental Control and Life Support System (ECLSS) engineering team, where she worked with the fledgling Commercial Orbital Transportation Services Program as an ECLSS integrator and managed the integration strategy between NASA and Russian ECLSS on the International Space Station. She also served as the lead system manager for emergency response, helping to develop the space station’s ammonia leak response and related hardware. Duchesne became a civil servant in 2017 when she was hired as a Mission Evaluation Room (MER) manager for the program’s Vehicle Office.

Duchesne said being a MER manager was a standout experience. “It was both humbling and inspiring to come to work every day knowing that I could pull from the best minds in the space industry to find a solution to any problem that came our way,” she said. Still, she is hard-pressed to identify a favorite role or project among her varied experiences. “I’ve been fortunate to work in a lot of different areas at NASA and experience perspectives that have all provided challenges, successes, and lessons learned.”
In her current role with CLDP, Duchesne applies her extensive space station experience to leading NASA’s Space Act Agreement with commercial space station developer Starlab Space. “I love being part of the future of low Earth orbit and being able to provide these new companies with lessons learned from my years working station and connecting our partners with all the knowledgeable subject matter experts at NASA,” she said. “It feels rewarding to help the commercial industry stand on our shoulders to do new great things.”
Beyond her technical work, Duchesne strives to provide an example to her colleagues by being her authentic self in the workplace and honoring those who do the same. “I think it is so important for all of us to create safe spaces for each person to bring their whole selves to what we’re trying to achieve,” she said. “People’s unique life experiences and backgrounds provide rich space for connection and different perspectives on problems that NASA is trying to solve.”
Duchesne takes pride in NASA’s celebration of diversity in the workplace, and the value the agency places on all team members being able to live and work openly and authentically. “I feel fortunate to work in a community where I’m able to live this value in front of my children, and all the younger generations, so that it is no longer considered exceptional, but expected in their future,” she said.
Outside of work, Duchesne enjoys spending time with her wife – who also works for NASA – and their three children. “We love family road trips which give us time to connect and be together. Our dog Aston is the real boss of the house and joins us on all of our adventures.”

She hopes to share with her children and other members of the Artemis Generation a love for exploring the unknown and the confidence to achieve greatness in their own ways. “I look forward to them taking the reins, using the unique skills and techniques they have honed in today’s world – which is different than the one we grew up in,” she said. “I know this next generation will continue to accomplish great things for our world and beyond doing it their way, with open mindedness, acceptance, and integrity. I hope they remain inspired by human ingenuity and the amazing things we can accomplish when we work together, while holding reverence and awe toward all that we don’t yet know.”
First of Its Kind Detection Made in Striking New Webb Image
Alignment of bipolar jets confirms star formation theories
For the first time, a phenomenon astronomers have long hoped to directly image has been captured by NASA’s James Webb Space Telescope’s Near-Infrared Camera (NIRCam). In this stunning image of the Serpens Nebula, the discovery lies in the northern area (seen at the upper left) of this young, nearby star-forming region.
Astronomers found an intriguing group of protostellar outflows, formed when jets of gas spewing from newborn stars collide with nearby gas and dust at high speeds. Typically these objects have varied orientations within one region. Here, however, they are slanted in the same direction, to the same degree, like sleet pouring down during a storm.
Image: Serpens Nebula (NIRCam) In this image of the Serpens Nebula from NASA’s James Webb Space Telescope, astronomers found a grouping of aligned protostellar outflows within one small region (the top left corner). Serpens is a reflection nebula, which means it’s a cloud of gas and dust that does not create its own light, but instead shines by reflecting the light from stars close to or within the nebula.
The discovery of these aligned objects, made possible due to Webb’s exquisite spatial resolution and sensitivity in near-infrared wavelengths, is providing information into the fundamentals of how stars are born.
“Astronomers have long assumed that as clouds collapse to form stars, the stars will tend to spin in the same direction,” said principal investigator Klaus Pontoppidan, of NASA’s Jet Propulsion Laboratory in Pasadena, California. “However, this has not been seen so directly before. These aligned, elongated structures are a historical record of the fundamental way that stars are born.”
So just how does the alignment of the stellar jets relate to the rotation of the star? As an interstellar gas cloud crashes in on itself to form a star, it spins more rapidly. The only way for the gas to continue moving inward is for some of the spin (known as angular momentum) to be removed. A disk of material forms around the young star to transport material down, like a whirlpool around a drain. The swirling magnetic fields in the inner disk launch some of the material into twin jets that shoot outward in opposite directions, perpendicular to the disk of material.
In the Webb image, these jets are signified by bright clumpy streaks that appear red, which are shockwaves from the jet hitting surrounding gas and dust. Here, the red color represents the presence of molecular hydrogen and carbon monoxide.
“This area of the Serpens Nebula – Serpens North – only comes into clear view with Webb,” said lead author Joel Green of the Space Telescope Science Institute in Baltimore. “We’re now able to catch these extremely young stars and their outflows, some of which previously appeared as just blobs or were completely invisible in optical wavelengths because of the thick dust surrounding them.”
Astronomers say there are a few forces that potentially can shift the direction of the outflows during this period of a young star’s life. One way is when binary stars spin around each other and wobble in orientation, twisting the direction of the outflows over time.
Stars of the SerpensThe Serpens Nebula, located 1,300 light-years from Earth, is only one or two million years old, which is very young in cosmic terms. It’s also home to a particularly dense cluster of newly forming stars (~100,000 years old), seen at the center of this image. Some of these stars will eventually grow to the mass of our Sun.
“Webb is a young stellar object-finding machine,” Green said. “In this field, we pick up sign posts of every single young star, down to the lowest mass stars.”
“It’s a very complete picture we’re seeing now,” added Pontoppidan.
So, throughout the region in this image, filaments and wisps of different hues represent reflected starlight from still-forming protostars within the cloud. In some areas, there is dust in front of that reflection, which appears here with an orange, diffuse shade.
This region has been home to other coincidental discoveries, including the flapping “Bat Shadow,” which earned its name when 2020 data from NASA’s Hubble Space Telescope revealed a star’s planet-forming disk to flap, or shift. This feature is visible at the center of the Webb image.
Video: A Tour Of The Serpens Nebula Future StudiesThe new image, and serendipitous discovery of the aligned objects, is actually just the first step in this scientific program. The team will now use Webb’s NIRSpec (Near-Infrared Spectrograph) to investigate the chemical make-up of the cloud.
The astronomers are interested in determining how volatile chemicals survive star and planet formation. Volatiles are compounds that sublimate, or transition from a solid directly to a gas, at a relatively low temperature – including water and carbon monoxide. They’ll then compare their findings to amounts found in protoplanetary disks of similar-type stars.
“At the most basic form, we are all made of matter that came from these volatiles. The majority of water here on Earth originated when the Sun was an infant protostar billions of years ago,” Pontoppidan said. “Looking at the abundance of these critical compounds in protostars just before their protoplanetary disks have formed could help us understand how unique the circumstances were when our own solar system formed.”
These observations were taken as part of General Observer program 1611. The team’s initial results have been accepted in the Astrophysical Journal.
The James Webb Space Telescope is the world’s premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and CSA (Canadian Space Agency).

The first of its kind inside the center’s secure area, the marker is the latest example of the center’s commitment to remembering its rich history as it continues to launch humanity’s future.
At the forefront of NASA Kennedy’s commitment to preservation is Katherine Zeringue, who serves as cultural resources manager, overseeing the center’s historic resources from buildings to historic districts to archaeological sites.
“Traditional approaches attempt to preserve things to a specific time period, including historic materials,” Zeringue said. “But that’s a challenge here because we still actively use our historic assets, which need to be modified to accommodate new missions and new spacecraft. Therefore, we rely on an adaptive reuse approach, in which the active use of a historic property helps to ensure its preservation.”
Many iconic structures are still in service at NASA Kennedy, like the Beach House where Apollo astronauts congregated with their families, the Vehicle Assembly Building where NASA rockets are still stacked, the Launch Control Center, and Launch Complex 39A. All told, 83 buildings, seven historic districts, and one National Historic Landmark are either listed or are eligible for listing on the National Register of Historic Places.
To conserve these resources, the spaceport follows a variety of federal laws, regulations, and executive orders, including the National Historic Preservation Act of 1966. This includes making a reasonable and good faith effort to identify any historic properties under its care and considering how its decisions affect historic properties.
“The Cultural Resources Management Program aims to balance historic preservation considerations with the agency’s mission and mandate to ensure reliable access to space for government and commercial payloads,” Zeringue said. “Finding that proper balance is challenging in the dynamic environment of our spaceport.”
Perhaps no other location embodies the center’s commitment to the past and the future more than Launch Complex 39A. Created in 1965, the launch complex was initially designed to support the Saturn V rocket, which powered the agency’s Apollo Program as it made numerous trips to the Moon. Outside of launching Skylab in 1973, the pad stood unused following Apollo’s end in 1972 until the agency’s Space Shuttle Program debuted in 1981. The transition from Apollo to space shuttle saw Launch Complex 39A transform from support of a single-use rocket to supporting the nation’s first reusable space launch and landing system.
By the time the program ended in 2011, 135 space shuttle launches had taken place within Kennedy’s boundary, 82 of which were at Launch Complex 39A. Many of those were among the program’s most notable, including the flights of astronauts Sally Ride, NASA’s first woman in space, and Guion Bluford, NASA’s first Black astronaut in space, as well as the first flight to the newly created International Space Station in 1998.
The launch complex began another transformation in 2014 when NASA signed a 20-year lease agreement with SpaceX as part of Kennedy’s transformation into a multi-user spaceport. SpaceX reconfigured Launch Complex 39A to support its Falcon 9 and Falcon Heavy rockets, which today launch robotic science missions and other government and commercial payloads, as well as crew and cargo to the space station. Apollo-era infrastructure is incorporated in the SpaceX Crew Launch Tower.
“Launch Complex 39A exemplifies the balance between historic preservation and supporting the mission,” Zeringue noted. “Each chapter of the space program brings change, and those changes become additional chapters in the center’s historical legacy as we continue to build the future in space exploration.”
