Breaking Records, Returning Asteroid Samples Among NASA’s Big 2023

Breaking Records, Returning Asteroid Samples Among NASA’s Big 2023

In 2023, as NASA pushed the limits of exploration for the benefit of humanity, the agency celebrated astronaut Frank Rubio becoming the first American astronaut to spend more than one year in space; delivered samples from an asteroid to Earth; sent a spacecraft to study a metal-rich asteroid for the first time; launched multiple initiatives to share climate data; advanced developments in sustainable aircraft; all while continuing preparations to send the first Artemis astronauts to the Moon.

“This year, NASA continued to make the impossible, possible while sharing our story of discovery with the world,” said NASA Administrator Bill Nelson. “We’ve launched missions that are helping tell the oldest stories of our solar system; continued to safely transport astronauts to the International Space Station to conduct groundbreaking science; our Earth satellites are providing critical climate data to all people; we’re making great strides to make aviation more dependable and sustainable; and we’re growing our commercial and international partnerships as we venture back to the Moon and on to Mars. NASA is home to the world’s finest workforce, and there is no limit to what we can achieve when we work together.”

In support of the Biden-Harris Administration’s efforts to address climate change, NASA is leading the development of U.S. government-wide initiatives focused on bringing Earth science information to the public. The Earth Information Center, a new interactive exhibit at NASA Headquarters in Washington, also includes an online experience that invites visitors to see Earth as NASA sees it from space while providing critical data needed by researchers and policymakers.

Among other notable mentions, the agency’s James Webb Space Telescope – the largest, most powerful telescope humanity has ever put in space – celebrated one year of science. NASA and the Defense Advanced Research Projects Agency (DARPA) announced the two organizations will partner on DRACO (Demonstration Rocket for Agile Cislunar Operations) to test a nuclear-powered rocket in space as soon as 2027.

This year NASA celebrated 25 years of International Space Station operations as the agency continued to foster the growth of the commercial space economy, supporting the development of commercial space station partnerships. It also marks the 65th anniversary of the agency. While celebrating these achievements, NASA also unveiled its NASA 2040 vision for the agency to ensure it remains a global leader in aerospace for decades to come.

Below are additional highlights of NASA’s endeavors in 2023 to explore the unknown in air and space, innovate for the benefit of humanity, and inspire the world through discovery.

Understanding Our Changing Planet

NASA has used its unique vantage point of space to better understand our changing planet since launching its first Earth science satellites in the 1960s. In 2023, NASA’s Office of the Chief Scientist established a cross-agency working group and released a climate strategy. Other agency efforts to share scientific data on Earth.gov and other areas include:

  • Working with its partners, NASA launched the U.S. Greenhouse Gas Center, opening access to trusted data on greenhouse gases.
    • Data from NASA’s Earth Surface Mineral Dust Source Investigation (EMIT) instrument aboard the International Space Station is part of the gas center. EMIT identifies point-source emissions of greenhouse gases with a proficiency greater than expected.
  • NASA’s tracking of greenhouse gases includes both global and focused estimates.
  • Building on the month-by-month worldwide temperature data collected and released by NASA and National Oceanic and Atmospheric Administration both agencies are expected to announce soon 2023 was the warmest year in recorded history.
  • A NASA airborne campaign helped show that methane ‘hot spots’ in the Yukon-Kuskokwim Delta are more likely to be found where recent wildfires burned into the tundra, altering carbon emissions from the land.
  • After successfully launching to space earlier this year, NASA’s TEMPO (Tropospheric Emissions: Monitoring of Pollution) mission to study air quality now is successfully transmitting information about major air pollutants over North America.
  • NASA’s SWOT (Surface Water and Ocean Topography) mission offered the its first detailed perspectives of Earth’s surface water.
  • Among natural hazards, NASA data was put to use in monitoring the heavy rains occurring in the drought-stricken areas, heat waves, wildfires, and subsequent health affects worldwide, as well as expansion of NASA landslide data.

Advancing Moon to Mars Exploration

This year, NASA shared results of its first Moon to Mars Architecture Concept Review as it builds a blueprint for human exploration throughout the solar system for the benefit of humanity. The agency also continues to take significant steps toward landing the first woman and first person of color on the Moon as part of Artemis. Notably in 2023, NASA announced crew for the Artemis II mission, the first Artemis mission with astronauts around the Moon and back to Earth. The crew completed fundamentals training, and is now focusing on training for mission operations. Additional highlights for human deep space exploration include:

  • All major elements for the SLS (Space Launch System) rocket for Artemis II are complete or nearing completion including booster segments delivered to NASA’s Kennedy Space Center in Florida and final core state assembly testing at NASA’s Michoud Assembly Facility in New Orleans.
  • Upgrades and refurbishments continue at Kennedy with the mobile launcher and launch pad, including a water flow test and launch operations simulation.
  • NASA made progress on Artemis III, which will send the first humans to explore the region near the lunar South Pole, building on the previous flight tests and adding a human landing system and advanced spacesuits for moonwalks.
  • The solid rocket booster segments and the four RS-25 engines are complete for the Artemis III SLS, as well as three of the five major core stage elements. Teams are integrating elements of Orion’s crew module, and the European Service Module.
  • NASA selected the geology team to develop a lunar surface science plan for Artemis III.  
  • Beyond Artemis III, teams completed welding the primary structure for Gateway’s HALO (Habitation and Logistics Outpost), where astronauts will live and work in lunar orbit. Fabrication is complete on the primary structure of the Power and Propulsion Element that will provide power, communications, and maintain Gateway’s orbit.
  • In addition to other hardware assembly and certification work for later missions, Artemis V will include a lunar terrain vehicle. NASA asked SpaceX to further develop Starship for Artemis IV, and also selected Blue Origin to develop a human lunar lander for Artemis V.
  • Experiments aboard the International Space Station focused on helping astronauts go farther and stay longer in space. This research included growing sustainable crops such as dwarf tomatoes, understanding how microbes adapt to space to protect crew health, and developing innovative materials that can weather the harsh environments of the Moon and Mars.

To support future NASA Moon missions with crew, the agency’s CLPS (Commercial Lunar Payload Services) initiative is in the final phases of preparations for the first two launches and landings to deliver NASA science and technology demonstrations to the lunar surface.

  • Five NASA payloads are aboard Astrobotic’s Peregrine Mission 1 lander, which is set to launch no earlier than Monday, Jan. 8. Soon after, another six NASA payloads will launch no earlier than Friday, Jan. 12, aboard Intuitive Machine’s Nova-C spacecraft.
  • Since launching CLPS, NASA has contracted with five companies for eight deliveries to the lunar surface. Most recently in 2023, NASA selected Firefly Aerospace for a delivery.
  • Among future CLPS payloads is NASA’s first robotic lunar rover, VIPER – short for the Volatiles Investigating Polar Exploration Rover. The rover will trek into permanently shadowed areas to unravel the mysteries of the Moon’s water and better understand the environment. In preparation for a landing in late 2024, scientists named VIPER’s mission area in honor of NASA mathematician Melba Roy Mouton. Development, assembly and testing also continues for the rover’s solar and battery systems.

While NASA is leading Artemis, international partnerships are a key part of advancing Moon to Mars exploration. In 2023, 10 additional countries signed the Artemis Accords, which lay out a common set of principles governing the civil exploration and use of outer space. So far, 33 countries have signed the Artemis Accords.

Maintaining Low Earth Orbit Operations

Closer to Earth, the International Space Station – humanity’s home in space – passed 25 years of operations. NASA and its partners officially extended operations plans for the microgravity science laboratory for the benefit of humanity. Other space station milestones in 2023 include:

  • NASA and SpaceX continued regular crew rotation flights to and from station, helping maximize science in space, including:
    • NASA astronauts Frank Rubio, Nicole Mann, Josh Cassada, Stephen Bowen, Woody Hoburg, Loral O’Hara, and Jasmin Moghbeli lived and worked aboard the station.
    • Rubio spent a U.S. record-breaking 371 days in space, contributing to a better understanding of long-duration spaceflight as we explore beyond our home planet.
    • Crew-5 returned to Earth with Mann and Cassada, as well as JAXA (Japan Aerospace Exploration Agency) astronaut Koichi Wakata, and Roscosmos cosmonaut Anna Kikina. Crew members tested hydroponic and aeroponic techniques to grow plants without using soil, released Uganda and Zimbabwe’s first satellites, studied how liquids move in a container in simulated lunar gravity to generate data to improve Moon rover designs, and reinstalled the station’s bioprinting facility.
    • Crew-6 included Bowen and Hoburg, as well as UAE (United Arab Emirates) astronaut Sultan Alneyadi and Roscosmos cosmonaut Andrey Fedyaev. The crew assisted a student robotic challenge, studying plant genetic adaptations to space, and monitoring human health in microgravity. The crew also released Saskatchewan’s first satellite, which tests a new radiation detection and protection system.
    • Crew-7 carried Moghbeli, ESA (European Space Agency) astronaut Andreas Mogensen, JAXA astronaut Satoshi Furukawa, and Roscosmos cosmonaut Konstantin Borisov. This crew is conducting a variety of scientific research in areas such the collection of microbial samples from the exterior of the space station, the first study of human response to different spaceflight durations, and a study on astronaut’s sleep.
  • NASA and Boeing continued to make progress on the company’s CST-100 Starliner spacecraft. Starliner and its crew of NASA astronauts Barry Wilmore and Sunita Williams are preparing for the first flight with astronauts in 2024, the final demonstration prior to regular flights to the microgravity complex.
  • Space station crew members completed 12 spacewalks to upgrade and conduct maintenance at the orbiting laboratory before the year’s end. NASA astronauts continued work to install the International Space Station Rollout Solar Arrays (IROSA), which will increase power generation capability by up to 30% when fully complete.
  • Six commercial cargo missions and international partner missions delivered about 28,000 pounds of science investigations, tools, and critical supplies to the space station. By year’s end about 12,500 pounds of investigations and equipment are planned to be returned researchers on Earth.
  • Space station crew members welcomed the second NASA-enabled private astronaut mission, Axiom Mission 2, to the orbital complex advancing the agency’s goal of commercializing low-Earth orbit. NASA also selected Axiom Space for the third private astronaut mission and signed an order for the fourth mission with the company.

Some additional key investigations launched, and operating, on station included NASA and ISS National Lab releasing a joint solicitation to address the goals of the Biden-Harris Administration’s Cancer Moonshot initiative, which aims to conduct science in space to help cure disease on Earth; NASA’s ILLUMA-T (Integrated Laser Communications Relay Demonstration Low-Earth-Orbit User Modem and Amplifier Terminal) is now on station, which aims to test high data rate laser communications via the agency’s LCRD (Laser Communications Relay Demonstration); upgraded NASA’s Cold Atom Laboratory to continue pioneering quantum discovery in space; and launched and installed its Atmospheric Wave Experiment on station to provide insight into how terrestrial weather impacts space weather, which may affect satellite communications and tracking in orbit.

Also on the commercial front, NASA partnered with seven U.S. companies with unfunded Space Act Agreements, and released its third Request for Information for commercials space station services, while working toward a formal call for proposals to provide the agency with low Earth orbit services after the space station’s retirement. Commercial space station partners met major design and engineering milestones, and are on track to serve as potential replacements for the agency’s microgravity research needs. Two companies also are combining efforts, which will allow NASA to apply funding to the other stations to accelerate development.

Reaching Farther into Solar System, Beyond

As part of its first year of operations, NASA’s Webb telescope pulled back the curtain on some of the farthest galaxies, stars, and black holes ever observed; solved a longstanding mystery about the early universe; found methane and carbon dioxide in the atmosphere of a planet outside our solar system; and offered new views and insights into our own cosmic backyard. Additional achievements beyond the solar system included:

  • NASA made important contributions to two missions that international partners launched this year: ESA’s Euclid mission to study dark energy and dark matter, as well as JAXA’s XRISM mission, a powerful new satellite that will revolutionize how we understand the hot, X-ray universe.
  • The Nancy Grace Roman Space Telescope, NASA’s next flagship observatory, finished camera assembly, and its coronagraph instrument passed its first big optics test.

Autumn was host to mission milestone events that showcased the importance of our solar system’s smaller bodies.

  • NASA’s OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer) spacecraft capped its seven-year journey with the successful deposit of a pristine sample of surface material from the asteroid Bennu in the Utah desert.
  • NASA showed off material from the asteroid Bennu for the first time. Initial studies of the 4.5-billion-year-old asteroid Bennu sample collected in space and brought to Earth show evidence of high-carbon content and water, which together could indicate the building blocks of life on Earth may be found in the rock.
  • The Psyche spacecraft launched from NASA Kennedy toward the asteroid Psyche.
  • NASA’s Lucy spacecraft conducted its first target asteroid flyby of asteroid Dinkinesh at the inner edge of the main asteroid belt, and the first images now are online.
  • An annular eclipse occurred on Oct. 14, visible in parts of the United States, Mexico, and many countries in South and Central America. NASA supported the event with engagement activities, as well as science research. Three Black Brant IX sounding rockets were launched to study the ionosphere – an electrically charged layer of the atmosphere – before, during, and after the peak eclipse.

NASA also kicked off Heliophysics Big Year, a public engagement campaign to make science and information accessible to all and showcase heliophysics-related efforts.

Technology Innovations to Benefit All

NASA’s Deep Space Optical Communications experiment launched aboard the Psyche spacecraft and achieved first light, beaming back a laser encoded with test data from nearly 10 million miles away. NASA will demonstrate data transmission rates 10 to 100 times greater than current radio frequency systems. The following are additional space technology advancements:

Evolving Aviation’s Frontier

In 2023, NASA advanced aviation and aeronautics technologies to improve passenger experiences, stimulate U.S. economic growth, and create a future of cleaner, quieter, safer skies. Through its Sustainable Flight National Partnership and other efforts, NASA supported the U.S. goal of reaching net-zero aviation greenhouse gas emissions by 2050, and the agency released a new strategic implementation plan to guide research for the next 20 years and beyond. NASA also:

  • Made new progress in its Quesst mission, as the X-59 quiet supersonic experimental aircraft had its tail structure installed and was moved from the assembly facility for structural testing.
  • Worked with Boeing on the Sustainable Flight Demonstrator project to produce and test the X-66A, a full-sized, experimental transonic truss brace wing aircraft that will inform a new generation of sustainable airliners.

Seeing and Believing: 15 Years of Exoplanet Images

At the upper left of a dark, star-filled sky is a bright, bluish light. It is the star Beta Pictoris with a glow around it showing the surrounding disk of debris.

Beta Pictoris is located about 60 light-years away toward the constellation of Pictor (the Painter’s Easel) and is one of the best-known examples of a star surrounded by a dusty debris disk. Earlier observations showed a warp of the disc, a secondary inclined disc and comets falling onto the star, all indirect, but tell-tale signs that strongly suggested the presence of a massive planet. Observations by ESO proved the presence of a planet around Beta Pictoris, and another planet was later discovered. To see the planets, we must block the light of the star.

Credits:
ESO/Digitized Sky Survey 2

First there was a gloriously dusty disk. Then the traceable tracks of “exocomets.” But 15 years ago this fall, the star system Beta Pictoris yielded one of the most iconic pictures in astrophysics: a direct image of a planet orbiting another star.

The young, bright star, some 63 light-years distant and visible to the naked eye, all but overwhelmed the faint light of the planet. When astronomers, using a European Southern Observatory telescope, subtracted the starlight, all that remained of the planet was a tiny dot, a few pixels. But it was enough to throw open a new window on direct imaging.

An exoplanet is seen as a tiny dotof light blue light next to a str that has been masked with a screen. Protruding from both sides are bright, yellow-orange jets. Those indicate the disk of debris.
This composite image represents the close environment of Beta Pictoris as seen in near infrared light. The exoplanet Beta Pictoris b is the small dot next to the masked star at the center. This very faint environment is revealed after a very careful subtraction of the much brighter stellar halo. The outer part of the image shows the reflected light on the dust disk, as observed in 1996 by a European Southern Observatory ground telescope. The newly detected source is more than 1000 times fainter than Beta Pictoris, aligned with the disc, at a projected distance of 8 times the Earth-Sun distance.
ESO/A.-M. Lagrange et al.

“After that, I knew what I wanted to do in astronomy,” said Marie Ygouf, a researcher who specializes in direct imaging of exoplanets – planets around other stars – at NASA’s Jet Propulsion Laboratory in Southern California.

An undergraduate when she first saw the image of the planet, called Beta Pictoris b, Ygouf said she was awestruck.

“It was so exciting to try to take pictures of exoplanets, to try to detect life on another planet,” she said. “I was sold.”

Today the Beta Pictoris system, called Beta Pic for short, is famous for the early, breathtaking images of its surrounding disk of dusty debris, and for abundant evidence of exocomets, or comets detected in star systems other than our own. The discovery of a second planet in the system, Beta Pictoris c, was revealed to much scientific excitement in 2018.

It is, as one astronomer said, the gift that keeps on giving.

But the scientists deeply involved in early observations of the system had a bit of an uphill struggle convincing some colleagues that their groundbreaking discoveries were real, said Anne-Marie Lagrange, an astronomer at LESIA, Observatoire de Paris, who has been working to understand the system for more than 30 years.

As an intern, Lagrange began her work on Beta Pic in the mid-1980s, just after the disk image made its big splash. Among her research milestones was the discovery, in the late 1980s, of massive clumps of gas falling onto the surface of the system’s central star – and at high rates of speed, up to 200 miles (350 kilometers) per second.

Lagrange and her fellow researchers relied on observations from the IUE (International Ultraviolet Explorer) satellite – “an ancestor” of NASA’s Hubble Space Telescope, she said – to propose that the infalling gas was caused by evaporating comets.

“They were the first exocomets [observed] around another star,” she said. “At the beginning, many people were laughing at it.” The findings held up, and the presence of exocomets in the system was confirmed by further observations announced in 2022.

With this technique, we may be able to answer that very fundamental question: Is there any life in the universe outside of Earth?”

Researcher on the Nancy Grace Roman Space Telescope science team

In the mid 1990s, relying on the recently launched Hubble as well as increasingly sophisticated ground-based instruments, scientists realized that the debris disk around Beta Pictoris was warped, like a vinyl record left too long in the Sun.

Computer modeling results suggested the warp was a gravitational skew caused by an orbiting planet. And in 2008, after long effort, Lagrange and her team hit paydirt: a direct image of the giant, gaseous planet, so young it was still glowing from its recent formation.

“The nice thing is, we predicted it 10 years before,” she said.

The future of exoplanet imaging

Still a relatively minor player in the detection of exoplanets, direct imaging’s role will expand in the years and decades to come, promising deep insights into the nature of distant planets as technology improves. But even then, each “image” of a planet will still be just a handful of pixels.

That might sound disappointing, especially in the era of spectacular sci-fi movie effects. If we find an “Earth-like” planet, we won’t see continents and oceans – at least not yet. But that tiny dot of light will contain a flood of information: details of the planet’s atmosphere, clouds, temperature, and perhaps even signs of some form of life.

By splitting the light from that tiny dot into a spectrum of colors, scientists can spot missing lines from that spectrum – slices of light absorbed by molecules in the planet’s atmosphere as starlight is reflected from the atmosphere or surface. The missing slices correspond to specific gases and molecules in the planet’s atmosphere, a detection method known as spectroscopy.

NASA’s James Webb Space Telescope is already using onboard spectrographs to tease out the components of exoplanet atmospheres. In the years ahead, the agency’s Nancy Grace Roman Space Telescope, to be launched by May 2027, is designed to study the cloudy atmospheres of mature, Jupiter-sized exoplanets. The Habitable Worlds Observatory, a mission concept now in the early planning stages, is expected to refine this technology, to measure the atmospheric composition of small, rocky planets like our own, all from those little dots of directly imaged exoplanets.

Ygouf is part of the project science team for the Roman telescope’s coronagraph instrument, which will block the glare from a parent star so the light from its planets can be detected. Meant to be a technology demonstration, the instrument includes two flexible mirrors to correct distortions in the light caused by the instrument and by the telescope itself.

She says the direct imaging techniques that caught fire with Beta Pictoris could someday solve one of the ultimate mysteries.

“With this technique, we may be able to answer that very fundamental question: Is there any life in the universe outside of Earth?” she said. “It’s astonishing, incredible, that from a few pixels we’ll be able to learn so many things about a planet: whether those planets are terrestrial or gaseous, whether they have an atmosphere or not. If it’s done right, in the future we may be able to create pretty maps of those planets, seeing potential clouds. It may be a few pixels, but [there’s] so much information you can get from that.”

NASA’s upcoming PACE mission will offer important insights on airborne particles of sea salt, smoke, human-made pollutants, and dust – collectively called aerosols – by observing how they interact with light. With PACE data, scientists will provide better answers to key questions such as how aerosols affect cloud formation or how ice clouds and liquid clouds differ. Understanding the nature of airborne particles and clouds is crucial to deciphering how climate and air quality are changing.

Two instruments on NASA’s upcoming PACE mission will look at aerosols and clouds – the A and C in the name of the Plankton, Aerosol, Cloud, ocean Ecosystem satellite. After launch in early 2024, the PACE mission will scan the Earth and gather data on the chemical composition, movement, and interaction of aerosols and clouds through the use of two cutting-edge polarimeters – instruments that measure light properties.

There are characteristics of light that we can see with our eyes, such as color. Other characteristics are invisible to the human eye, like what scientists call polarization.

“Polarization is something that we don’t have an intuitive sense for because our eyes don’t see it,” said Kirk Knobelspiesse, polarimetry lead for the PACE mission at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “If you saw the world through eyes that could see polarization, like our sensors can, you would see rainbows everywhere.”  

Light leaving the Sun moves in all different directions like a wave – this is called unpolarized light, said Brian Cairns, deputy project scientist for PACE. When it interacts with something like a cloud or an aerosol particle, however, light can oscillate more in one direction than the others: It is now polarized light. This quirk of light behavior can help scientists learn more about the characteristics and interactions of aerosols and water droplets in the sky.

Polarimeters measure the angle at which the light is polarized, which reveals specific characteristics of whatever the light had bounced off of. With these instruments, scientists can piece together the size, composition, abundance, and other traits of the particles in the atmosphere.

In the scene, the sun was positioned low in the sky directly behind the viewer so that backscattered light is observed. While this observation geometry is rare from the surface of the earth, it will be common for PACE/HARP2.

The two polarimeters on PACE – HARP2 and SPEXone – make a great pair because of the complementary differences in what they measure. HARP2, built at the University of Maryland, Baltimore County, will observe four wavelengths of light from up to 60 different angles. SPEXone, built at the Netherlands Institute for Space Research (SRON) and Airbus Netherlands B.V., will peer down at a narrower swath, using five viewing angles but looking at light at hyperspectral resolution – the full range of colors in a rainbow. Together the polarimeters will offer a picture of Earth’s atmosphere in unprecedented detail.

Scientists have been observing aerosols from space for decades, though the community has not had polarimetry data for a decade, noted Otto Hasekamp, senior scientist at SRON. PACE will provide polarimeter data from multiple vantage points and, due to technological advancements in the instruments, the data will be of better quality than ever before.

“It’s exciting to see the culmination of working actively on instrument models and prototypes,” said Jeroen Rietjens, instrument scientist at SRON, “then finally seeing it end up on a real satellite.”

The instrument is neatly wrapped in grey thermal blankets and still has the red radiator cover in place. It is surreal to realize that In a few months it will be staring at the Earth and collecting multi-angle spectro-polarimetric data that will enable scientists to infer the amount and type of aerosols in the Earth atmosphere and contribute to a better understanding of the effects of aerosols on climate,” said Rietjens.

After PACE is launched in early 2024, the satellite will scan Earth every two days, gathering immense quantities of data on the chemical composition, movement, and interaction of aerosols and clouds.

“We want to measure properties of aerosols because aerosols affect climate,” said Hasekamp. They reflect light back into space and can also absorb it, which plays a role in how much of the Sun’s energy reaches Earth’s surface. Aerosols also affect cloud formation and properties, but the details of these relationships are not fully known to scientists. The data PACE collects will help to clarify some of these unknowns.

The new polarimetry data will also offer real-time insights on air pollution. “PACE measurements will not only answer fundamental science questions, but will also improve people’s quality of life,” said Marcela Loría-Salazar, assistant professor at the School of Meteorology at the University of Oklahoma and PACE early adopter. The PACE Early Adopters program promotes the integration of PACE data into practical applications of science.

Loría-Salazar is particularly interested in how aerosols change over time and with location, with an extra emphasis on the altitude of aerosols over the middle of the United States. There, PACE will allow scientists to identify aerosols, while also deciphering what they mean for air quality.

The measurements from PACE’s polarimeters will also help improve our understanding of Earth’s climate. By adding PACE atmospheric data to models, scientists will be able to replace the estimates now used to fill data gaps in those models with data from current measurements.

“I’m hoping to help gather the data that will reduce model uncertainty and help us make better predictions for how we expect our climate to play out in the next decades and centuries,” Knobelspiesse said.

NASA’s Commercial Partners Continue Progress on New Space Stations

NASA’s Commercial Partners Continue Progress on New Space Stations

Three NASA-funded commercial space station partners are on track for the design and development of their orbital destinations and the transition of agency’s low Earth orbit needs from the International Space Station.

“We are ending the year on a high note with multiple important milestones being completed by our partners,” said Angela Hart, manager of the Commercial Low Earth Orbit Development Program at NASA Johnson Space Center in Houston. “Over the past few months, we have been able to dig into the details of the specific hardware and processes of these stations and are moving forward to multiple comprehensive design reviews next year.”

Axiom Space

Axiom Space, which holds a firm-fixed price, indefinite-delivery, indefinite-quantity contract with NASA, is on schedule to launch and attach its first module, named Axiom Hab One, to the International Space Station in 2026. A total of four modules are planned for the Axiom Commercial Segment attached to the station. After the space station’s retirement, the Axiom Commercial Segment will separate and become a free-flying commercial destination named Axiom Station.

The hatches of the Axiom Hab One module are fabricated and prepared to undergo pressure testing to ensure a strong enough seal to withstand the vacuum of space. Manufacturing of the Axiom Hab One module is underway, and the critical design review will occur in 2024. During this review, NASA will assess the maturity of the Axiom Space design and provide feedback necessary to ensure safe operations when it is attached to the International Space Station.

Orbital Reef

NASA engineers work alongside Blue Origin team members to conduct testing on prototype windows for the Orbital Reef commercial space station.
Blue Origin

Blue Origin, which NASA awarded a Space Act Agreement in 2021 to develop a free-flying space station named Orbital Reef, recently completed tests for a window system and a structural demonstration.

For the structural test, Blue Origin used a prototype of their space station’s main module, called the Core, to demonstrate the manufacturing processes required to build the final pressurized modules of the station. The test supports validation of the structural models and analytical tools for the Core’s structural design.

The International Space Station’s cupola, a room with seven windows overlooking the Earth, is the cornerstone of crewed missions for both research and astronaut morale. Orbital Reef will incorporate multiple windows on its Core, with each window spanning about twice the size of a car windshield. For the window test, Blue Origin evaluated the window integration structure design concept and its performance against the pressures and temperatures the windows will be exposed to while in orbit.

Starlab

NASA also awarded Starlab, a station being developed by Voyager Space’s Exploration Segment, a Space Act Agreement in 2021. Voyager Space recently announced a partnership with Airbus and Northrop Grumman. Voyager’s Exploration Segment, which includes Nanoracks, recently completed three milestones: a system definition review and the initiation of two pairs of milestones for an optical link demonstration and alternative urine processor demonstration.

Free-space optical, also called laser communications, allows for higher data rates and more energy-efficient communications than radio frequency communication systems. A major goal of the optical communication demonstration is to conduct testing from the International Space Station to the ground to establish the capabilities needed for Starlab. This initial milestone, within the optical link demonstration milestone pair scope, validated the Starlab testing plan. The optical link is planning to be tested next on the International Space Station.

As on the International Space Station, Starlab will recover purified water from urine to reduce water needed to resupply the station. Starlab will test an alternative urine processor under realistic operating conditions to validate functional performance and reduce implementation risk. Similar to the optical link demonstration, the processor demonstration is divided into a pair of milestones, with this initial completed milestone validating the testing plan.

Starlab’s third recently completed milestone was a system definition review. Teams examined how NASA’s potential commercial space station requirements aligned to the functional areas of the Starlab system to define the space station architecture. The completion of this milestone initiated preparations for the next step in the comprehensive review process, the preliminary design review.

NASA is working closely with commercial companies to develop new space stations capable of providing services to NASA and others, which will ensure that the U.S. maintains a continuous human presence in low Earth orbit and provides direct benefits for people on Earth. Leading into NASA’s future procurement for commercial low Earth orbit services, the agency recently released its third request for information.

The last Wednesday in November proved to be a full-circle moment for two engineers at NASA’s Stennis Space Center near Bay St. Louis, Mississippi.

Josh Greiner heard a familiar voice on the headset as he prepared to conduct an RS-25 engine test on the Fred Haise Test Stand on Nov. 29. It was Peyton Pinson, speaking from the same nearby test complex building where he and Greiner once shared a cubicle as interns seven years earlier.

As Greiner listened in, Pinson announced he would conduct a hot fire on the E-1 Test Stand for commercial company Launcher Space in 30 minutes. 

“It was a pretty cool moment,” Greiner said. “We used to sit there and look at the test conductor kind of in awe and were amazed they could keep up with all these different console operators at the same time. Now, we both are part of the test team and both part of the rotation that gets to conduct tests.”

Pinson and Greiner arrived at NASA Stennis in May 2016 to participate in the NASA Pathways work study (co-op) program. Pinson was a mechanical engineering major at Mississippi State University in Starkville. Greiner, still unsure of what direction he wanted to go in the field, was majoring in aerospace engineering at the University of Alabama in Tuscaloosa. He ultimately finished with a mechanical engineering degree and credits his work study experience for providing clarity for his future.

“If you can get a co-op, I’m 100 percent in favor of that,” Greiner said. “You get exposure to a breadth of disciplines that make it a lot easier to start narrowing in what you really want to do. In college, we all come out with a pretty standardized foundation of engineering that’s an incredible knowledge base, but you really learn a lot with on-the-job training. Getting to the right place with the right people is going to help your growth more so than getting the perfect engineering degree.”

The right place proved to be NASA Stennis. Pinson and Greiner spent multiple semesters soaking up knowledge from the experienced, diverse workforce at the south Mississippi NASA center. They rotated throughout the center complex where teams fulfill NASA and commercial space company test needs.

“When we started as co-ops, Josh and I were given a good bit of responsibility and trusted with a lot,” Pinson said. “We had so many people who were a part of the team that really wanted to help us learn and develop and get to where we are now.”

After completing the work-study program and earning their degrees, Pinson and Greiner were hired by NASA in 2018.

“Our management put us in a position to be successful,” Greiner said. “We started running consoles as co-ops, and they helped move us onto the test stands with projects that had a lot going on and gave us a huge share of responsibility in leading projects early in our career.”

Both now have years of experience that includes conducting various engine tests, such as the successful Nov. 29 hot fires at the nation’s premier rocket engine test site.

“We all work together in the mechanical operations group to get to that point,” Pinson said. “There’s a lot of opportunity for a new mechanical operations engineer to learn along the way and to sit in the test conductor seat with an experienced test conductor to back you up and guide you through it. Eventually, you have enough on-the-job training to run it yourself.”
