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.
  • Enhanced transonic truss braced wing research for sustainable aircraft designs using wind tunnel tests for model wings and supercomputing to look at aircraft concepts.
  • Used NASA’s DC-8 flying lab to test emissions from Boeing’s ecoDemonstrator Explorer aircraft to evaluate sustainable aviation fuels’ effects on contrails..
  • Progressed its Electrified Powertrain Flight Demonstration project, which works to create hybrid powertrains for regional and single-aisle aircraft, with GE Aerospace and magniX testing power systems and demonstrator aircraft
  • Entered into an agreement with the U.S. Air Force AFWERX Agility Prime program that will allow NASA to test a new air taxi from the manufacturer Joby Aviation to see how such vehicles could fit into the national airspace
  • Debuted the Advanced Capabilities for Emergency Response Operations project, which uses drones and advanced aviation technologies to improve wildland fire coordination and operations, and tested a mobile air traffic management kit.
  • Demonstrated a breakthrough, 3D-printable, high-temperature-resistant alloy called GRX-810 that could be used for applications like components of aircraft and rocket engines.

Aeronautics efforts led to advancements in construction of the Flight Dynamics Research Facility, the agency’s first major wind tunnel in more than 40 years. NASA used simulators to collect data on how operating electric air taxis could affect pilots and passengers, and gathered data on new ways to use aviation including autonomous air cargo delivery and air taxi operations. Finally, research from the X-57 Maxwell provided aviation researchers with hundreds of lessons learned, as well as revolutionary development in areas ranging from battery technology to cruise motor control design.

      Sols 4511-4512: Low energy after a big weekend?
      This image was taken by Left Navigation Camera onboard NASA’s Mars rover Curiosity on Sol 4510 (2025-04-14 03:43:40 UTC). NASA/JPL-Caltech Written by Lauren Edgar, Planetary Geologist at USGS Astrogeology Science Center
      Earth planning date: Monday, April 14, 2025
      We all know the feeling: it’s Monday morning after a big weekend and you’re coming into the week wishing you’d had a little more time to rest and recharge.  Well, Curiosity probably feels the same way today. Curiosity accomplished a lot over the weekend, including full contact science, a MAHLI stereo imaging test, testing the collection of ChemCam passive spectral data at the same time as data transmission with one of the orbiters, and some APXS and MAHLI calibration target activities, plus a long 57 m drive. It was great to see all of those activities in the plan and to see some great drive progress. But that means we’re a bit tight on power for today’s plan!
      I was on shift as Long Term Planner today, and the team had to think carefully about science priorities to fit within our power limit for today’s plan, and how that will prepare us for the rest of the week.  The team still managed to squeeze a lot of activities into today’s 2-sol plan. First, Curiosity will acquire Mastcam mosaics to investigate local stratigraphic relationships and diagenetic features. Then we’ll acquire some imaging to document the sandy troughs between bedrock blocks to monitor active surface processes. We’ll also take a Navcam mosaic to assess atmospheric dust. The science block includes a ChemCam LIBS observation on the bedrock target “Santa Margarita” and a long distance RMI mosaic of “Ghost Mountain” to look for possible boxwork structures. Then Curiosity will use the DRT, APXS and MAHLI to investigate the finely-laminated bedrock in our workspace at a target named “The Grotto.”  We’ll also collect APXS and MAHLI data on a large nodule in the workspace named “Torrey Pines” (meanwhile the Torrey Pines here on Earth was shaking in today’s southern California earthquakes! All is well but it gave some of our team members an extra jolt of adrenaline right before the SOWG meeting).  The second sol is focused on continuing our drive to the south and taking post-drive imaging to prepare for Wednesday’s plan.
      Phew! Good job Curiosity, you made it through Monday.

      NASA’s Lucy spacecraft is 6 days and less than 50 million miles (80 million km) away from its second close encounter with an asteroid; this time, the small main belt asteroid Donaldjohanson.
      Download high-resolution video and images from NASA’s Scientific Visualization Studio.
      NASA/Dan Gallagher This upcoming event represents a comprehensive “dress rehearsal” for Lucy’s main mission over the next decade: the exploration of multiple Trojan asteroids that share Jupiter’s orbit around the Sun. Lucy’s first asteroid encounter – a flyby of the tiny main belt asteroid Dinkinesh and its satellite, Selam, on Nov. 1, 2023 – provided the team with an opportunity for a systems test that they will be building on during the upcoming flyby.
      Lucy’s closest approach to Donaldjohanson will occur at 1:51pm EDT on April 20, at a distance of 596 miles (960 km). About 30 minutes before closest approach, Lucy will orient itself to track the asteroid, during which its high-gain antenna will turn away from Earth, suspending communication. Guided by its terminal tracking system, Lucy will autonomously rotate to keep Donaldjohanson in view. As it does this, Lucy will carry out a more complicated observing sequence than was used at Dinkinesh. All three science instruments – the high-resolution greyscale imager called L’LORRI, the color imager and infrared spectrometer called L’Ralph, and the far infrared spectrometer called L’TES – will carry out observation sequences very similar to the ones that will occur at the Trojan asteroids.
      However, unlike with Dinkinesh, Lucy will stop tracking Donaldjohanson 40 seconds before the closest approach to protect its sensitive instruments from intense sunlight.
      “If you were sitting on the asteroid watching the Lucy spacecraft approaching, you would have to shield your eyes staring at the Sun while waiting for Lucy to emerge from the glare. After Lucy passes the asteroid, the positions will be reversed, so we have to shield the instruments in the same way,” said encounter phase lead Michael Vincent of Southwest Research Institute (SwRI) in Boulder, Colorado. “These instruments are designed to photograph objects illuminated by sunlight 25 times dimmer than at Earth, so looking toward the Sun could damage our cameras.” 
      Fortunately, this is the only one of Lucy’s seven asteroid encounters with this challenging geometry. During the Trojan encounters, as with Dinkinesh, the spacecraft will be able to collect data throughout the entire encounter.
      After closest approach, the spacecraft will “pitch back,” reorienting its solar arrays back toward the Sun. Approximately an hour later, the spacecraft will re-establish communication with Earth.
      “One of the weird things to wrap your brain around with these deep space missions is how slow the speed of light is,” continued Vincent. “Lucy is 12.5 light minutes away from Earth, meaning it takes that long for any signal we send to reach the spacecraft. Then it takes another 12.5 minutes before we get Lucy’s response telling us we were heard. So, when we command the data playback after closest approach, it takes 25 minutes from when we ask to see the pictures before we get any of them to the ground.”
      Once the spacecraft’s health is confirmed, engineers will command Lucy to transmit the science data from the encounter back to Earth, which is a process that will take several days.
      Donaldjohanson is a fragment from a collision 150 million years ago, making it one of the youngest main belt asteroids ever visited by a spacecraft. 
      “Every asteroid has a different story to tell, and these stories weave together to paint the history of our solar system,” said Tom Statler, Lucy mission program scientist at NASA Headquarters in Washington. “The fact that each new asteroid we visit knocks our socks off means we’re only beginning to understand the depth and richness of that history. Telescopic observations are hinting that Donaldjohanson is going to have an interesting story, and I’m fully expecting to be surprised – again.”
      NASA’s Goddard Space Flight Center in Greenbelt, Maryland, designed and built the L’Ralph instrument and provides overall mission management, systems engineering and safety and mission assurance for Lucy. Hal Levison of SwRI’s office in Boulder, Colorado, is the principal investigator. SwRI, headquartered in San Antonio, also leads the science team and the mission’s science observation planning and data processing. Lockheed Martin Space in Littleton, Colorado, built the spacecraft, designed the original orbital trajectory and provides flight operations. Goddard and KinetX Aerospace are responsible for navigating the Lucy spacecraft. The Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, designed and built the L’LORRI (Lucy Long Range Reconnaissance Imager) instrument. Arizona State University in Tempe, Arizona, designed and build the L’TES (Lucy Thermal Emission Spectrometer) instrument. Lucy is the thirteenth mission in NASA’s Discovery Program, which is managed by NASA’s Marshall Space Flight Center in Huntsville, Alabama.

      Eclipses, Science, NASA Firsts: Heliophysics Big Year Highlights 
      One year ago today, a total solar eclipse swept across the United States. The event was a cornerstone moment in the Heliophysics Big Year, a global celebration of the Sun’s influence on Earth and the entire solar system. From October 2023 to December 2024 — a period encompassing two solar eclipses across the U.S., two new NASA heliophysics missions, and one spacecraft’s history-making solar flyby — NASA celebrated the Sun’s widespread influence on our lives.

      An annular (or “ring of fire”) solar eclipse occurred Oct. 14, 2023, and kicked off the Helio Big Year with a bang. Millions of people across North America witnessed the Moon crossing in front of the Sun, creating this brilliant celestial event. NASA’s live broadcast had more than 11 million views across different platforms.  
      On Oct. 14, 2023, an annular solar eclipse crossed North, Central, and South America. Visible in parts of the United States, Mexico, and many countries in South and Central America, millions of people in the Western Hemisphere were able to experience this “ring of fire” eclipse. NASA’s official broadcast and outreach teams were located in Kerrville, TX, and Albuquerque, NM, to capture the event and celebrate with the communities in the path of annularity. 
      Credit: NASA/Ryan Fitzgibbons  Before the eclipse, NASA introduced the 2023 Eclipse Explorer, an interactive map to explore eclipse details for any location in the United States. NASA shared tips on eclipse safety, including through a video with NSYNC’s Lance Bass and even with an augmented reality filter. 
      Scientists also studied conditions during the annular eclipse with sounding rockets, balloons, and amateur radio.  
      Total Solar Eclipse 
      On April 8, 2024, millions of people across North America experienced a total solar eclipse that darkened parts of 15 U.S. states in the path of totality.  
      Ahead of the event, NASA hosted a widespread safety campaign, handed out over 2 million solar viewing glasses, and produced an interactive map to help viewers plan their viewing experience. On eclipse day, NASA also hosted a live broadcast from locations across the country, drawing over 38 million views. 
      Researchers studied the eclipse and its effects on Earth using a variety of techniques, including international radar networks, scientific rockets, weather balloons, and even high-altitude NASA WB-57 jets. Several NASA-funded citizen science projects also conducted experiments. These projects included more than 49,000 volunteers who contributed an astounding 53 million observations.  
      This infographic shares metrics from citizen science projects that occurred during the total solar eclipse on April 8, 2024. NASA/Kristen Perrin “We have opened a window for all Americans to discover our connection to the Sun and ignited enthusiasm for engaging with groundbreaking NASA science, whether it’s through spacecraft, rockets, balloons, or planes,” said Kelly Korreck, a Heliophysics program scientist at NASA Headquarters in Washington. “Sharing the excitement of NASA heliophysics with our fellow citizens has truly been amazing.” 
      Science Across the Solar System 
      NASA’s heliophysics missions gather data on the Sun and its effects across the solar system.  
      The Atmospheric Waves Experiment (AWE) mission launched from NASA’s Kennedy Space Center in Florida Nov. 9, 2023, and was installed on the International Space Station nine days later. This mission studies atmospheric gravity waves, how they form and travel through Earth’s atmosphere, and their role in space weather. 
      Orbital footage from the International Space Station shows NASA’s Atmospheric Waves Experiment (AWE) as it was extracted from SpaceX’s Dragon cargo spacecraft. NASA/International Space Station On Nov. 4, 2024, the Coronal Diagnostic Experiment (CODEX) mission also launched to the space station, where it studies the solar wind, with a focus on what heats it and propels it through space.  
      Pictured is the CODEX instrument inside the integration and testing facility at NASA’s Goddard Space Flight Center. NASA/CODEX team The Aeronomy of Ice in the Mesosphere (AIM) mission ended after 16 years studying Earth’s highest clouds, called polar mesospheric clouds.  
      An artist’s concept shows the Aeronomy of Ice in the Mesosphere (AIM) spacecraft orbiting Earth.   NASA’s Goddard Space Flight/Center Conceptual Image Lab  NASA’s Ionospheric Connection Explorer (ICON) also ended after three successful years studying the outermost layer of Earth’s atmosphere, called the ionosphere. 
      NASA’s 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’s Goddard Space Flight Center/Conceptual Image Lab  Voyager has been operating for more than 47 years, continuing to study the heliosphere and interstellar space. In October 2024, the Voyager 1 probe stopped communicating. The mission team worked tirelessly to troubleshoot and ultimately reestablish communications, keeping the mission alive to continue its research.  
      In this artist’s conception, NASA’s Voyager 1 spacecraft has a bird’s-eye view of the solar system. The circles represent the orbits of the major outer planets: Jupiter, Saturn, Uranus, and Neptune. Launched in 1977, Voyager 1 visited the planets Jupiter and Saturn. The spacecraft is now 13 billion miles from Earth, making it the farthest and fastest-moving human-made object ever built. In fact, Voyager 1 is now zooming through interstellar space, the region between the stars that is filled with gas, dust, and material recycled from dying stars. NASA’s Hubble Space Telescope is observing the material along Voyager’s path through space. NASA/STSci While the goal of the NASA heliophysics fleet is to study the Sun and its influence, these missions often make surprising discoveries that they weren’t originally designed to. From finding 5,000 comets to studying the surface of Venus, NASA highlighted and celebrated these bonus science connections during the Helio Big Year. 
      Solar Maximum 
      Similar to Earth, the Sun has its own seasons of activity, with a solar minimum and solar maximum during a cycle that lasts about 11 years. The Helio Big Year happened to coincide with the Sun’s active period, with NASA and NOAA announcing in October 2024 that the Sun had reached solar maximum, the highest period of activity. Some of the largest solar storms on current record occurred in 2024, and the largest sunspot in nearly a decade was spotted in the spring of 2024, followed by a colossal X9.0 solar flare Oct. 3, 2024.  
      Sunspots are cooler, darker areas on the solar surface where the Sun’s magnetic field gets especially intense, often leading to explosive solar eruptions. This sunspot group was so big that nearly 14 Earths could fit inside it! The eruptions from this region resulted in the historic May 2024 geomagnetic storms, when the aurora borealis, or northern lights, were seen as far south as the Florida Keys.

      The Big Finale: Parker’s Close Approach to the Sun 
      NASA’s Parker Solar Probe holds the title as the closest human-made object to the Sun. On Dec. 24, 2024, Parker made history by traveling just 3.8 million miles from the Sun’s surface at a whopping 430,000 miles per hour.  
      “Flying this close to the Sun is a historic moment in humanity’s first mission to a star,” said Nicky Fox, associate administrator, Science Mission Directorate, NASA Headquarters. 
      Controllers have confirmed NASA’s mission to “touch” the Sun survived its record-breaking closest approach to the solar surface on Dec. 24, 2024. 
      Credit: NASA/Joy Ng Parker Solar Probe’s close approach capped off a momentous Heliophysics Big Year that allowed NASA scientists to gather unprecedented data and invited everyone to celebrate how the Sun impacts us all. In the growing field of heliophysics, the Helio Big Year reminded us all how the Sun touches everything and how important it is to continue studying our star’s incredible influence.  
      A Big Year Ahead 
      Though the Helio Big Year is over, heliophysics is only picking up its pace in 2025. We remain in the solar maximum phase, so heightened solar activity will continue into the near future. In addition, several new missions are expected to join the heliophysics fleet by year’s end. 
      The PUNCH mission, a set of four Sun-watching satellites imaging solar eruptions in three dimensions, and EZIE, a trio of Earth-orbiting satellites tracing the electrical currents powering Earth’s auroras, have already launched. The LEXI instrument, an X-ray telescope studying Earth’s magnetosphere from the Moon, also launched through NASA’s CLPS (Commercial Lunar Payload Services) initiative. 
      Future missions slated for launch include TRACERS, which will investigate the unusual magnetic environment near Earth’s poles, and ESCAPADE, venturing to Mars to measure the planet’s unique magnetic environment. 
      The last two missions will share a ride to space. The Carruthers Geocorona Observatory will look back at home, studying ultraviolet light emitted by the outermost boundaries of our planet’s atmosphere. The IMAP mission will instead look to the outermost edges of our heliosphere, mapping the boundaries where the domain of our Sun transitions into interstellar space.

      Image: This image shows Webb’s recent observation of the asteroid 2024 YR4 using both its Near-Infrared Camera (NIRCam) and Mid-Infrared Instrument (MIRI). Data from NIRCam shows reflected light, while the MIRI observations show thermal light.
      On 8 March 2025, the NASA/ESA/CSA James Webb Space Telescope turned its watchful eye toward asteroid 2024 YR4, which we now know poses no significant threat to Earth in 2032 and beyond.
      This is the smallest object targeted by Webb to date, and one of the smallest objects to have its size directly measured.
      Observations were taken to study the thermal properties of 2024 YR4, including how quickly it heats up and cools down and how hot it is at its current distance from the Sun. These measurements indicate that this asteroid does not share properties observed in larger asteroids. This is likely a combination of its fast spin and lack of fine-grained sand on its surface. Further research is needed, however this is considered consistent with a surface dominated by rocks that are roughly fist-sized or larger.
      Asteroid 2024 YR4 was recently under close watch by the team at ESA's Near Earth Objects Coordination Centre, located in Italy. Planetary defence experts from the Agency's Space Safety programme worked with NASA and the international asteroid community to closely watch this object and refine its orbit, which was eventually determined to not pose a risk of Earth impact. Read details on this unusual campaign via ESA's Rocket Science blog and in news articles here and here.
      Webb’s observations indicate that the asteroid measures roughly 60 meters (comparable to the height of a 15-story building).
      The new observations from Webb not only provide unique information about 2024 YR4’s size, but can also complement ground-based observations of the object's position to help improve our understanding of the object’s orbit and future trajectory.
      Note: This post highlights data from Webb science in progress, which has not yet been through the peer-review process.
