NASA’s LRO Views ispace HAKUTO-R Mission 2 Moon Lander Impact Site

NASA - Breaking News - Fri, 06/20/2025 - 1:10pm

On June 11, NASA’s LRO (Lunar Reconnaissance Orbiter) captured photos of the site where the ispace Mission 2 SMBC x HAKUTO-R Venture Moon (RESILIENCE) lunar lander experienced a hard landing on June 5, 2025, UTC.

RESILIENCE was launched on Jan. 15 on a privately funded spacecraft.

LRO’s right Narrow Angle Camera (one in a suite of cameras known as LROC) captured the images featured here from about 50 miles above the surface of Mare Frigoris, a volcanic region interspersed with large-scale faults known as wrinkle ridges.

The dark smudge visible above the arrow in the photo formed as the vehicle impacted the surface, kicking up regolith — the rock and dust that make up Moon “soil.” The faint bright halo encircling the site resulted from low-angle regolith particles scouring the delicate surface.

This animation shows the RESILIENCE site before and after the impact. In the image, north is up. Looking from west to east, or left to right, the area pictured covers 2 miles.Credit: NASA/Goddard/Arizona State University. 

LRO is managed by NASA’s Goddard Space Flight Center in Greenbelt, Maryland, for the Science Mission Directorate at NASA Headquarters in Washington. Launched on June 18, 2009, LRO has collected a treasure trove of data with its seven powerful instruments, making an invaluable contribution to our knowledge about the Moon. NASA is returning to the Moon with commercial and international partners to expand human presence in space and bring back new knowledge and opportunities.

NASA Air Taxi Passenger Comfort Studies Move Forward

NASA - Breaking News - Fri, 06/20/2025 - 12:22pm

Research continues to better understand how humans may interact with these new types of aircraft.NASA/Steve Freeman

NASA’s Advanced Air Mobility vision involves the skies above the U.S. filled with new types of aircraft, including air taxis. But making that vision a reality involves ensuring that people will actually want to ride these aircraft – which is why NASA has been working to evaluate comfort, to see what passengers will and won’t tolerate. 

NASA is conducting a series of studies to understand how air taxi motion, vibration, and other factors affect ride comfort. The agency will provide the data it gathers to industry and others to guide the design and operational practices for future air taxis. 

“The results of this study can guide air taxi companies to design aircraft that take off, land, and respond to winds and gusts in a way that is comfortable for the passengers,” said Curt Hanson, senior flight controls researcher for this project based at NASA’s Armstrong Flight Research Center in Edwards, California. “Passengers who enjoy their experience in an air taxi are more likely to become repeat riders, which will help the industry grow.” 

The air taxi comfort research team uses NASA Armstrong’s Ride Quality Laboratory as well as the Human Vibration Lab and Vertical Motion Simulator at NASA’s Ames Research Center in California’s Silicon Valley to study passenger response to ride quality, as well as how easily and precisely a pilot can control and maneuver aircraft. 

After pilots checked out the simulator setup, the research team conducted a study in October where NASA employees volunteered to participate as passengers to experience the virtual air taxi flights and then describe their comfort level to the researchers.

Studies continue to better understand passenger comfort for future air taxi rides.NASA/Steve Freeman

Using this testing, the team produced an initial study that found a relationship between levels of sudden vertical motion and passenger discomfort. More data collection is needed to understand the combined effect of motion, vibration, and other factors on passenger comfort. 

“In the Vertical Motion Simulator, we can investigate how technology and aircraft design choices affect the handling qualities of the aircraft, generate data as pilots maneuver the air taxi models under realistic conditions, and then use this to further investigate passenger comfort in the Ride Quality and Human Vibration Labs,” said Carlos Malpica, senior rotorcraft flight dynamics researcher for this effort based at NASA Ames. 

This work is managed by the Revolutionary Vertical Lift Technology project under NASA’s Advanced Air Vehicles Program in support of NASA’s Advanced Air Mobility mission, which seeks to deliver data to guide the industry’s development of electric air taxis and drones.

Summer Begins in Northern Hemisphere

NASA - Breaking News - Fri, 06/20/2025 - 12:17pm
This full-disk image from NOAA’s GOES-13 satellite shows the Americas at the start of astronomical summer in the Northern Hemisphere on June 21, 2012.NASA

This full-disk image from NOAA’s GOES-13 satellite was captured at 7:45 a.m. EDT (11:45 UTC) and shows the Americas on June 21, 2012, the start of astronomical summer – in the Northern Hemisphere – that year.

The first day of summer in 2025 is June 20; it is also the longest day of the year. In the Southern Hemisphere, it’s the shortest day of the year and the beginning of winter.

Earth orbits at an angle, so the Northern Hemisphere is tilted toward the Sun half of the year — this is summer in the Northern Hemisphere, and winter in the Southern Hemisphere. The other half of the year, the Northern Hemisphere is tilted away from the Sun, creating winter in the north and summer in the south. Solstices happen twice per year, at the points in Earth’s orbit where this tilt is most pronounced.

Preparations for Next Moonwalk Simulations Underway (and Underwater)

In the summer 2025 issue of the NASA History Office’s News & Notes newsletter, examples of leadership and critical decision-making in NASA’s history form the unifying theme. Among the topics discussed are NASA’s Shuttle-Centaur program, assessing donations to the NASA Archives, how the discovery of the first exoplanet orbiting a sun-like star catalyzed NASA’s exoplanet program, and Chief of the Medical Operations Office Charles A. Berry’s decisions surrounding crew health when planning the Project Gemini missions.

Featured Articles From the Chief Historian

By Brian Odom

NASA’s is a history marked by critical decisions. From George Mueller’s 1963 decision for “all up” testing of the Saturn V rocket to Michael Griffin’s 2006 decision to launch a final servicing mission to the Hubble Space Telescope, the agency has continually met key inflection points with bold decisions. These choices, such as the decision to send a crewed Apollo 8 mission around the Moon in December 1968, stand at the center of the agency’s national legacy and promote confidence in times of crisis.  Continue Reading

Shuttle-Centaur: Loss of Launch Vehicle Redundancy Leads to Discord

By Robert Arrighi

“Although the Shuttle/Centaur decision was very difficult to make, it is the proper thing to do, and this is the time to do it.” With those words on June 19, 1986, NASA Administrator James Fletcher canceled the intensive effort to integrate the Centaur upper stage with the Space Shuttle to launch the Galileo and Ulysses spacecraft. The decision, which was tied to increased safety measures following the loss of Challenger several months earlier, brought to the forefront the 1970s decision to launch all U.S. payloads with the Space Shuttle.

By Kate Mankowski

On January 27, 1967, Mission AS-204 (later known as Apollo 1) was conducting a simulated countdown when a fire suddenly broke out in the spacecraft, claiming the lives of astronauts Virgil I. “Gus” Grissom, Edward H. White, and Roger B. Chaffee. The disaster highlighted the risks that come with spaceflight and the work that still needed to be accomplished to meet President Kennedy’s challenge of going to the Moon before the end of the decade. With the complexity of the Apollo spacecraft, discerning the cause of the fire proved to be incredibly difficult. Continue Reading

The Fight to Fund AgRISTARS

By Brad Massey

Robert MacDonald, the manager of NASA’s Large Area Crop Inventory Experiment (LACIE), was not pleased in January 1978 after he read a draft copy of the U.S. General Accounting Office’s (GAO’s) “Crop Forecasting by Satellite: Progress and Problems” report. The draft’s authors argued that LACIE had not achieved its goals of accurately predicting harvest yields in the mid-1970s. Therefore, congressional leaders should “be aware of the disappointing performance of LACIE to date when considering the future direction of NASA’s Landsat program and the plans of the Department of Agriculture.” Continue Reading

The Hubble Space Telescope: The Right Project at the Right Time

By Jillian Rael

This year, NASA commemorates 35 years of the Hubble Space Telescope’s study of the cosmos. From observations of never-before-seen phenomena within our solar system, to the discovery of distant galaxies, the confirmation of the existence of supermassive black holes, and precision measurements of the universe’s expansion, Hubble has made incredible contributions to science, technology, and even art. Yet, for all its contemporary popularity, the Hubble program initially struggled for congressional approval and consequential funding. For its part, NASA found new ways to compromise and cut costs, while Congress evaluated national priorities and NASA’s other space exploration endeavors against the long-range value of Hubble.

Orbit Shift: How 50 Pegasi b Helped Pull NASA Toward the Stars in the 1990s

By Lois Rosson

On October 20, 1995, the New York Times reported the detection of a distant planet orbiting a Sun-like star. The star, catalogued as 51 Pegasi by John Flamsteed in the 18th century, was visible to the naked eye as part of the constellation Pegasus—and had wobbled on its axis just enough that two Swiss astronomers were able to deduce the presence of another object exerting its gravitational pull on the star’s rotation. The discovery was soon confirmed by other astronomers, and 51 Pegasi b was heralded as the first confirmed exoplanet orbiting a star similar to our own Sun. Continue Reading

By Jennifer Ross-Nazzal

In 1963, critical decisions had to be made about NASA’s upcoming Gemini missions if the nation were to achieve President John F. Kennedy’s lunar goals. Known as the bridge to Apollo, Project Gemini was critical to landing a man on the Moon by the end of the decade and returning him safely to Earth. The project would demonstrate that astronauts could rendezvous and dock their spacecraft to another space vehicle and give flight crews the opportunity to test the planned extravehicular capabilities in preparation for walking on the lunar surface on future Apollo flights. Perhaps most importantly, Gemini had to show that humans could live and work in space for long periods of time, a fiercely debated topic within and outside of the agency.  Continue Reading

By Sandra Johnson

As we walked into Bob McCall’s Arizona home, it quickly became obvious that two talented and creative people lived there. Tasked with interviewing one of the first artists to be invited to join the NASA Art Program, our oral history team quickly realized the session with McCall would include a unique perspective on NASA’s history. We traveled to Arizona in the spring of 2000 to capture interviews with some of the pioneers of spaceflight and had already talked to an eclectic group of subjects in their homes, including a flight controller for both Gemini and Apollo, an astronaut who had flown on both Skylab and Space Shuttle missions, a former NASA center director, and two former Women’s Airforce Service Pilots (WASPs) who ferried airplanes during WWII. However, unlike most interviews, the setting itself provided a rare glimpse into the man and his inspiration.  Continue Reading

Tasked with interviewing one of the first artists to be invited to join the NASA Art Program, our oral history team quickly realized the session with McCall would include a unique perspective on NASA’s history. We traveled to Arizona in the spring of 2000 to capture interviews with some of the pioneers of spaceflight and had already talked to an eclectic group of subjects in their homes, including a flight controller for both Gemini and Apollo, an astronaut who had flown on both Skylab and Space Shuttle missions, a former NASA center director, and two former Women’s Airforce Service Pilots (WASPs) who ferried airplanes during WWII. However, unlike most interviews, the setting itself provided a rare glimpse into the man and his inspiration.  Continue Reading

Inside the Archives: Biomedical Branch Files

By Alejandra Lopez

The Biomedical Branch Files (1966–2008) in the Johnson Space Center archives showcase the inner workings of a NASA office established to perform testing to provide a better understanding of the impacts of spaceflight on the human body. Ranging from memos and notes to documents and reports, this collection is an invaluable resource on the biomedical research done with NASA’s Apollo, Skylab, Space Shuttle, and Space Station projects. Files in the collection cover work done by groups within the branch such as the Toxicology, Microbiology, Clinical, and Biochemistry Laboratories. It also reveals the branch’s evolution and changes in its decision-making process over the years. Continue Reading

Marking the first public day of this year’s International Paris Air Show, the President of France Emmanuel Macron visited the Paris Space Hub.  

ESA Director General Josef Aschbacher and Director of Human and Robotic Exploration Daniel Neuenschwander welcomed President Macron, introducing him to the assembled French astronauts and a group of young space professionals in attendance.  

French ESA astronaut Sophie Adenot joined by video link from the United States, where she is training for her upcoming mission to the International Space Station. Sophie detailed some of her training, explaining that no two days are alike. Fellow astronauts Thomas Pesquet, Jean-François Clervoy and Claudie Haignéré also addressed Sophie and offered their advice for her time in space. Together President Macron and Sophie announced that her mission will be named εpsilon, and revealed her mission patch.

Speaking about the development of the space industry, President Macron said Europe must increase investment in commercial space, and emphasised the importance of complementarity of public and private investment – particularly with the upcoming ESA Council at Ministerial level and ongoing discussions for the next EU multiannual financial framework. He also mentioned the developing need for dual-use space capacity including surveillance. President Macron highlighted the importance of research and of making Europe a destination for researchers in line with the EU Choose Europe for Science initiative. He also called on Europe to improve its competitiveness in space. Watch a replay of the visit.  

A new Letter of Intent between the European Space Agency and Dassault Aviation was also announced, signalling the common interest of the organisations in working on low Earth orbit exploration, in particular orbital vehicles.
