JAXA (Japan Aerospace Exploration Agency) researchers examined the structures of four titanium-based compounds solidified in levitators in microgravity and on the ground and found that the internal microstructures were generally similar. These results could support development of new materials for use in space manufacturing.
To produce glass or metal alloys on Earth, raw materials are placed into a container and heated. But reactions between the container and the materials can cause imperfections. The JAXA Electrostatic Levitation Furnace can levitate, melt, and solidify materials without a container. The facility enables measurement of the thermophysical properties of high temperature melts and could accelerate development of innovative materials such as heat resistant ceramics for use in the aerospace and energy industries.

Carbon stored or sequestered in forests can help offset emissions that cause climate change, and improved estimates of tropical forest biomass could allow researchers to better evaluate these ecosystems and their offset contributions.
Global Ecosystem Dynamics Investigation (GEDI) provides high-resolution global observations of Earth’s forests and topography. These observations provide information on carbon and water cycling processes, biodiversity, and habitat, including quantifying carbon stored in vegetation and the potential for future carbon storage. The researchers suggest that estimates of tropical forest biomass could be further improved with data from new satellite missions and by integrating GEDI with dynamic vegetation models that include trait data.

NASA/Nick Hague Research indicates that refractive eye surgery is safe, effective, and suitable for astronauts. The study documented stable vision in two astronauts who, a few years prior to flight, underwent photorefractive keratectomy (PRK) and laser-assisted in situ keratomileusis (LASIK), respectively. These visual correction procedures can reduce the logistical complications of wearing glasses or contact lenses in space.
International Space Station Medical Monitoring collects health data from crew members before, during, and after spaceflight. The medical evaluation requirements, including vision assessment, apply to all crew members and are part of efforts by all international partners to maintain crew health, ensure mission success, and enable crew members to return to normal life on Earth after their missions.
NASA astronauts Terry Virts (bottom) and Scott Kelly (top) perform eye exams as part of ongoing studies into crew vision health. NASA JAXA researchers report that accurately assessing the velocity of airflow in front of a spreading flame makes it possible to predict the flammability of thin, flat materials in microgravity. These results mean it could be possible to use ground tests to predict the flammability of solid materials and thus ensure fire safety in spacecraft and space habitations.
The JAXA Fundamental Research on International Standard of Fire Safety in Space – Base for Safety of Future Manned Missions (FLARE) investigation tested the flammability of various solid materials in different configurations, including filter paper. Microgravity significantly affects combustion phenomena such as the spread of flame over solid materials; while flames cannot spread over solid materials under low-speed oxygen flow in Earth’s gravity, they can in microgravity due to the lack of buoyancy. Testing of the flammability of materials for spacecraft previously has not considered the effect of gravity, and results from this investigation could address this issue, significantly improving fire safety on future exploration missions.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
As students head back to school, teachers have a new tool that brings NASA satellite data down to their earthly classrooms.
The My NASA Data homepage categorizes content by areas of study called spheres and also Earth as a system. NASA/mynasadata.larc.nasa.gov For over 50 years of observing Earth, NASA’s satellites have collected petabytes of global science data (that’s millions and millions of gigabytes) – with terabytes more coming in by the day. Since 2004, the My NASA Data website has been developing ways for students and teachers of grades 3-12 to understand, and visualize NASA data, and to help incorporate those measurements into practical science lessons.
“We have three different types of lesson plans, some of which are student-facing and some are teacher-facing,” said Angie Rizzi, My NASA Data task lead, based at NASA’s Langley Research Center in Hampton, Virginia. “Teachers can download complete lesson plans or display a wide variety of Earth data. There are also lessons written for students to interact with directly.”
An image from My NASA Data’s Earth System Data Explorer visualization tool showing the monthly leaf index around the world as measured by NASA satellites in August 2020. Data parameters for this visualization were set to biosphere under the sphere dropdown and vegetation as a category. NASA/mynasadata.larc.nasa.gov A key component of the My NASA Data site is the newly updated Earth System Data Explorer visualization tool, which allows users to access and download NASA Earth data. Educators can explore the data then create custom data tables, graphs, and plots to help students visualize the data. Students can create and investigate comparisons between land surface temperatures, cloud cover, extreme heat, and a wide range of other characteristics for a specific location or region around the globe.
An image from My NASA Data’s visualization tool showing various searchable categories under the atmosphere dataset selection. NASA/mynasadata.larc.nasa.gov “The Earth System Data Explorer tool has a collection of science datasets organized by different spheres of the Earth system,” explained Desiray Wilson, My NASA Data scientific programmer. The program highlights six areas of study: atmosphere, biosphere, cryosphere, geosphere, hydrosphere, and Earth as a system. “The data goes as far back as the 1980s, and we are getting more daily datasets. It’s really good for looking at historical trends, regional trends, and patterns.”
My NASA Data had over one million site visits last year, with some of the most popular searches focusing on temperatures, precipitation, water vapor, and air quality.
My NASA Data program leaders and instructors collaborating with educators from the North Carolina Space Grant at NASA’S Langley Research Center June 26, 2024. Teachers were at NASA Langley as part of the North Carolina Space Education Ambassadors (NCSEA) program and were given demonstrations of the My NASA Data website. NASA/David C. Bowman Natalie Macke has been teaching for 20 years and is a science teacher at Pascack Hills High School in Montvale, New Jersey. Teachers like Macke help shape the lessons on the site through internships with the My NASA Data team. Teachers’ suggestions were also incorporated to enhance the visualization tool by adding new features that now allow users to swipe between visual layers of data and make side-by-side comparisons. Users can also now click on a location to display latitude and longitude and variable data streamlining the previous site which required manual input of latitude and longitude.
“The new visualization tool is very much a point-and-click layout like our students are used to in terms of just quickly selecting data they want to see,” said Macke. “Instantaneously, a map of the Earth comes up, or just the outline, and they can get the satellite view. So if they’re looking for a specific city, they can find the city on the map and quickly grab a dataset or multiple datasets and overlay it on the map to make visual comparisons.”

The image below shows the same map layered with atmospheric measurements.NASA/mynasadata.larc.nasa.gov The East Coast of the United States shown with monthly daytime surface (skin) temperatures from August 2023 overlayed from Earth-observing satellite data using the My NASA Data Earth System Data Explorer visualization tool. The image above shows the same region without the data layer added.NASA/mynasadata.larc.nasa.gov/ Even more valuable than creating visualizations for one specific lesson, elaborated Macke, is the opportunity My NASA Data provides for students to understand the importance of interpreting, verifying, and using datasets in their daily lives. This skill, she said, is invaluable, because it helps spread data literacy enabling users to look at data with a discriminating eye and learn to discern between assumptions and valid conclusions.
“Students can relate the data map to literally what’s happening outside their window, showing them how NASA Earth system satellite data relates to real life,” said Macke. “Creating a data literate public – meaning they understand the context and framework of the data they are working with and realizing the connection between the data and the real world – hopefully will intrigue them to continue to explore and learn about the Earth and start asking questions. That’s what got me into science when I was a little kid.”

The Apollo 11 mission in July 1969 completed the goal set by President John F. Kennedy in 1961 to land a man on the Moon and return him safely to the Earth before the end of the decade. At the time, NASA planned nine more Apollo Moon landing missions of increasing complexity and an Earth orbiting experimental space station. No firm human space flight plans existed once these missions ended in the mid-1970s. After taking office in 1969, President Richard M. Nixon chartered a Space Task Group (STG) to formulate plans for the nation’s space program for the coming decades. The STG’s proposals proved overly ambitious and costly to the fiscally conservative President who chose to take no action on them.

Right: President Lyndon B. Johnson addresses a crowd during a March 1968 visit to the Manned Spacecraft Center, now NASA’s Johnson Space Center, in Houston.
On May 25, 1961, before a Joint Session of Congress, President John F. Kennedy committed the United States to the goal, before the decade was out, of landing a man on the Moon and returning him safely to the Earth. President Kennedy reaffirmed the commitment during an address at Rice University in Houston in September 1962. Vice President Lyndon B. Johnson, who played a leading role in establishing NASA in 1958, under Kennedy served as the Chair of the National Aeronautics and Space Council. Johnson worked with his colleagues in Congress to ensure adequate funding for the next several years to provide NASA with the needed resources to meet that goal.
Following Kennedy’s assassination in November 1963, now President Johnson continued his strong support to ensure that his predecessor’s goal of a Moon landing could be achieved by the stipulated deadline. But with increasing competition for scarce federal resources from the conflict in southeast Asia and from domestic programs, Johnson showed less interest in any space endeavors to follow the Apollo Moon landings. NASA’s annual budget peaked in 1966 and began a steady decline three years before the agency met Kennedy’s goal. From a budgetary standpoint, the prospects of a vibrant, post-Apollo space program didn’t look all that rosy, the triumphs of the Apollo missions of 1968 and 1969 notwithstanding.

Less than a month after assuming the Presidency in January 1969, Richard M. Nixon appointed a Space Task Group (STG), led by Vice President Spiro T. Agnew as the Chair of the National Aeronautics and Space Council, to report back to him on options for the American space program in the post-Apollo years. Members of the STG included NASA Acting Administrator Thomas O. Paine (confirmed by the Senate as administrator on March 20), the Secretary of Defense, and the Director of the Office of Science and Technology. At the time, the only approved human space flight programs included lunar landing missions through Apollo 20 and three long-duration missions to an experimental space station based on Apollo technology that evolved into Skylab.
Beyond a general vague consensus that the United States human space flight program should continue, no approved projects existed once these missions ended by about 1975. With NASA’s intense focus on achieving the Moon landing within President Kennedy’s time frame, long-term planning for what might follow the Apollo Program garnered little attention. During a Jan. 27, 1969, meeting at NASA chaired by Acting Administrator Paine, a general consensus emerged that the next step after the Moon landing should involve the development of a 12-person earth-orbiting space station by 1975, followed by an even larger outpost capable of housing up to 100 people “with a multiplicity of capabilities.” In June, with the goal of the Moon landing almost at hand, NASA’s internal planning added the development of a space shuttle by 1977 to support the space station, the development of a lunar base by 1976, and the highly ambitious idea that the U.S. should prepare for a human mission to Mars as early as the 1980s. NASA presented these proposals to the STG for consideration in early July in a report titled “America’s Next Decades in Space.”

Still bathing in the afterglow of the successful Moon landing, the STG presented its 29-page report “The Post-Apollo Space Program: Directions for the Future” to President Nixon on Sep. 15, 1969, during a meeting at the White House. In its Conclusions and Recommendations section, the report noted that the United States should pursue a balanced robotic and human space program but emphasized the importance of the latter, with a long-term goal of a human mission to Mars before the end of the 20th century. The report proposed that NASA develop new systems and technologies that emphasized commonality, reusability, and economy in its future programs. To accomplish these overall objectives, the report presented three options:
Option I – this option required more than a doubling of NASA’s budget by 1980 to enable a human Mars mission in the 1980s, establishment of a lunar orbiting space station, a 50-person Earth orbiting space station, and a lunar base. The option required a decision by 1971 on development of an Earth-to-orbit transportation system to support the space station. The option maintained a strong robotic scientific and exploration program.
Option II – this option maintained NASA’s budget at then current levels for a few years, then anticipated a gradual increase to support the parallel development of both an earth orbiting space station and an Earth-to-orbit transportation system, but deferred a Mars mission to about 1986. The option maintained a strong robotic scientific and exploration program, but smaller than in Option I.
Option III – essentially the same as Option II but deferred indefinitely the human Mars mission.
In separate letters, both Agnew and Paine recommended to President Nixon to choose Option II.

The White House released the report to the public at a press conference on Sep. 17 with Vice President Agnew and Administrator Paine in attendance. Although he publicly supported a strong human spaceflight program, enjoyed the positive press he received when photographed with Apollo astronauts, and initially sounded positive about the STG options, President Nixon ultimately chose not to act on the report’s recommendations. Nixon considered these plans too grandiose and far too expensive and relegated NASA to one America’s domestic programs without the special status it enjoyed during the 1960s. Even some of the already planned remaining Moon landing missions fell victim to the budgetary axe.
On Jan. 4, 1970, NASA had to cancel Apollo 20 since the Skylab program needed its Saturn V rocket to launch the orbital workshop. In 1968, then NASA Administrator James E. Webb had turned off the Saturn V assembly line and none remained beyond the original 15 built under contract. In September 1970, reductions in NASA’s budget forced the cancellation of two more Apollo missions, and in 1971 President Nixon considered cancelling two more. He reversed himself and they flew as Apollo 16 and Apollo 17 in 1972, the final Apollo Moon landing missions.

More than two years after the STG submitted its report, in January 1972 President Nixon directed NASA Administrator James C. Fletcher to develop the Space Transportation System, the formal name for the space shuttle, the only element of the recommendations to survive the budgetary challenges. NASA anticipated the first orbital flight of the program in 1979, with the actual first flight occurring two years later. Twelve years elapsed after Nixon’s shuttle decision when President Ronald W. Reagan approved the development of a space station, the second major component of the STG recommendation. 14 years later, the first element of that program reached orbit. In those intervening years, NASA had redesigned the original American space station, leading to the development of a multinational orbiting laboratory called the International Space Station. Humans have inhabited the space station continuously for the past quarter century, conducting world class and cutting edge scientific and engineering research. Work on the space station helps enable future programs, returning humans to the Moon and later sending them on to Mars and other destinations.
