About 23 million people live in Taiwan, a Pacific island about the size of Maryland. Despite its size, the island produces a tremendous amount of agricultural goods per year—about $18 billion, according to Taiwan’s Ministry of Agriculture.
The average size of a farm in Taiwan (less than 1 hectare) is much smaller than in the United Kingdom (87 hectares) or the United States (187 hectares). Since much of the island is mountainous, only about one-quarter of Taiwan’s land is arable, and it is mostly located on the southwestern side of the island in the Chianan Plain. That amounts to 0.03 hectares of farmland per Taiwanese citizen—about half as much arable farmland as there is per person in the United Kingdom and one-tenth as much as in the United States.
The small plot size is apparent in this satellite image of farmland in Yunlin County in southwestern Taiwan, one of the island’s most productive agricultural areas. The small size of farms is partly a result of past policies that limited the size of farms and partly a byproduct of cultural traditions that often lead to the division of farms into smaller parcels as property is passed from one generation to the next.
Located along the floodplains of the Zhoushui and Beigang rivers, Yunlin County is mostly flat, has fertile soils, and enjoys easy access to irrigation water. The county, one of Taiwan’s main agricultural hubs, is known for producing a wide range of crops, including rice, sweet potatoes, peanuts, corn, sugarcane, garlic, scallions, coffee, fruit trees, and leafy greens. Farms in the county also raise millions of pigs, the most of any county in Taiwan.
Most crops in Yunlin County are grown in small rectangular plots defined by roadways and networks of irrigation canals. The exception is sugarcane, which was grown widely in the county in the early 1900s when Japan controlled Taiwan and established an expansive network of sugarcane plantations in the southwestern part of the country. These plantations were consolidated into Taiwan Sugar Corporation after the conclusion of World War II, and the large plot sizes in the farmland north of Baozhong in the image above persist as a legacy of this period.
While the amount of sugarcane cultivated in Taiwan has declined in recent decades and many of the fields have transitioned to other crops, Taiwan Sugar Corporation still raises sugarcane around Baozhong. The company operates a railway that transports harvested cane to nearby Huwei, site of one of just a few remaining sugar refineries on the island. While Taiwan also once had a large network of sugar railways that serviced thousands of kilometers of track and dozens of sugar refineries, the line that serves Huwei is the only one on the island that remains active.
Another area that stands out in the mosaicked agricultural landscape of Yunlin is located around Xiluo (above). Here the fields take on an unusual greenish-blue hue, largely because of the ubiquity of shade nets. Farmers use the nets to protect crops from heat, sun, heavy rains, and pests. They’re generally deployed for specialty crops such as vegetables, fruit, and flowers. This area contrasts with the darker green region in the lower right of the first image, where rice is the dominant crop.

The National Space Club & Foundation announced its annual award recipients March 13, 2026, in Washington, D.C.
Two dedicated leaders from NASA’s Johnson Space Center were recognized for their contributions to human spaceflight.
Orion Program Manager Howard Hu received the Norman L. Baker Astronautics Engineer Award for sustained technical contributions to multiple human spaceflight efforts.
Hu leads the design, development, production, and operations of Orion, NASA’s spacecraft for Artemis missions to the Moon. He has held several leadership roles within the Orion program, including deputy program manager, a manager of the Avionics, Power, and Software Office, and deputy manager of the Vehicle Integration Office. Hu has supported Orion since its inception, beginning as the Vehicle System Performance and Analysis lead.
On April 1, 2026, Artemis II launched on a 10-day voyage around the Moon, marking the first crewed flight of the Orion spacecraft. NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen splashed down safely inside Orion April 10 in the Pacific Ocean off the coast of San Diego. At their farthest point, the crew and spacecraft traveled 252,756 miles from Earth, setting a new record for the greatest distance traveled by humans in space.
The mission successfully proved the capability of Orion’s critical systems such as life support with humans aboard. Data from Artemis II will help refine mission operations and further evaluate Orion’s performance in deep space, supporting future Artemis missions.
NASA and its partners are now shifting their focus to Artemis III, which will test integrated operations between Orion and the human landing system in lunar orbit and advance plans to return astronauts to the Moon.
Before joining Orion, Hu served in multiple technical and leadership roles at Johnson, including chief engineer for exploration in the Aeroscience and Flight Mechanics Division, project manager and co-developer of shuttle abort flight management software for the Space Shuttle Cockpit Avionics Upgrades Program, and deputy guidance, navigation, and control system manager for the International Space Station program.
International Space Station Program Manager Dana Weigel received the Eagle Manned Mission Award. She leads development, integration, and operations for the International Space Station. The space station celebrated a historic milestone on Nov. 2, 2025, marking 25 years of continuous human habitation. The orbiting laboratory remains a critical testbed for future commercial destinations in low Earth orbit and for deep space exploration, supporting Artemis missions and future human missions to Mars.
Weigel has held several leadership roles within the program, including deputy chief of the Flight Director Office, where she led the Extravehicular Activity Recovery Team following a major in-flight spacewalk anomaly. She also served as a NASA flight director for STS-123 and led the agency’s geosynchronous Earth orbit satellite servicing habitat study.
Selected by panels of experts across industry, government, and academia, the awards reflect achievements that advance aerospace and national interests. Honorees were recognized at the 69th Annual Robert H. Goddard Memorial Dinner at the Washington Hilton.
“Dana Weigel and Howard Hu’s contributions to human space exploration, through their leadership and roles within the agency, are paramount,” said Johnson Director Vanessa Wyche. “It was a privilege to be there in person to celebrate and champion them as they were recognized for the lasting impact of their work. Congratulations to Dana, Howard, and all the award recipients on this well-deserved recognition.”
Hu and Weigel’s service exemplifies the leadership and technical excellence that continue to advance U.S. human space exploration.

As part of NASA’s SpaceX Crew-13 mission, four crew members from three space agencies will launch no earlier than mid-September to the International Space Station for a long-duration science expedition.
NASA astronauts Jessica Watkins and Luke Delaney will serve as spacecraft commander and pilot, respectively. They will be joined by CSA (Canadian Space Agency) astronaut Joshua Kutryk and Roscosmos cosmonaut Sergey Teteryatnikov, who will serve as mission specialists. After arriving at the orbiting laboratory, Crew-13 will become members of the space station’s Expedition 75.
This flight is the 13th crew rotation with SpaceX to the space station as part of NASA’s Commercial Crew Program. NASA is advancing the launch date of Crew-13 from November to help increase the frequency of U.S. crew rotation missions to the space station. The crew will conduct scientific investigations and technology demonstrations to help prepare humans for future exploration missions to the Moon and Mars, and benefit people on Earth.
This will be the second flight to the space station for Watkins, who was selected as a NASA astronaut in 2017. Watkins grew up in Lafayette, Colorado, and earned an undergraduate degree in geological and environmental sciences from Stanford University, as well as a doctorate in geology from the University of California, Los Angeles. As a geologist, she studied the Martian surface and was a member of the Curiosity rover science team at NASA’s Jet Propulsion Laboratory in Southern California. Watkins first launched to the space station as a crew member aboard NASA’s SpaceX Crew-4 mission, spending a total of 170 days in space across Expeditions 67/68 in 2022. She will be the first NASA astronaut to launch aboard a SpaceX Dragon spacecraft twice.
Selected as a NASA astronaut in 2021, Delaney earned a bachelor’s degree in mechanical engineering at the University of North Florida and a master’s degree in aerospace engineering at the Naval Postgraduate School. The Florida native is a distinguished naval aviator who participated in exercises throughout the Asia Pacific region and conducted missions in support of Operation Enduring Freedom. As a test pilot, Delaney evaluated developmental aircraft systems and served as a test pilot instructor. He also worked as a research pilot at NASA’s Langley Research Center in Hampton, Virginia, where he supported airborne science missions. This is the first spaceflight for Delaney.
The Crew-13 mission also is the first spaceflight for Kutryk. Prior to his selection as a CSA astronaut in 2017, he served as a CF-18 fighter pilot, flying missions in support of Canada’s NATO, U.N., and North American Aerospace Defense Command commitments. A native of Fort Saskatchewan, Alberta, Kutryk also worked as an experimental and operational test pilot at the Aerospace Engineering Test Establishment in Cold Lake, Alberta. Kutryk received a bachelor’s degree in mechanical engineering from the Royal Military College of Canada in Kingston, Ontario, and he is a distinguished graduate of the United States Air Force Test Pilot school in Edwards, California. He has master’s degrees in space studies, flight test engineering, and defense studies.
Crew-13 will be Teteryatnikov’s first trip to the orbiting laboratory. He graduated from the Naval Academy, St. Petersburg, Russia, in 2011 as an engineer specializing in ship power plant operations. Before his selection as a test cosmonaut, Teteryatnikov served in various naval engineering roles, including undersea vessels and specialized engine room operations. He was selected for the Gagarin Research and Test Cosmonaut Training Center Cosmonaut Corps in 2021 and has served as a test cosmonaut since 2023.
For more than 25 years, people have lived and worked continuously aboard the International Space Station, advancing scientific knowledge and making research breakthroughs that aren’t possible on Earth. The space station helps NASA understand and overcome the challenges of human spaceflight, expand commercial opportunities in low Earth orbit, and build on the foundation for long-duration missions to the Moon, as part of the Artemis program, and to Mars.

Preparations are underway for launch of NASA’s Nancy Grace Roman Space Telescope as soon as early September on a SpaceX Falcon Heavy rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. The Roman space telescope will provide deep, panoramic views of the cosmos, generating never-before-seen pictures that will revolutionize our understanding of the universe. Before Roman arrives at the launch pad, however, the telescope will complete final inspections, checkouts, and fueling at NASA Kennedy’s Payload Hazardous Servicing Facility (PHSF).
The 40-year-old facility is a dedicated dual-use complex for clean room and hazardous material operations, where numerous spacecraft have undergone final prelaunch processing including receiving, integration, testing, and encapsulation ahead of liftoff. NASA’s Launch Services Program, based at NASA Kennedy, manages the launch service for the Roman mission.
To prepare for Roman’s arrival, the program oversaw several upgrades to the PHSF. This included replacing its air-shower system, a small entry chamber that blasts high-velocity HEPA-filtered air onto people and equipment before they enter a clean room.
“Roman is a very sensitive spacecraft. NASA is always pushing the boundaries of how precise our instruments can be, and the result of that is they need to be very well cared for while they’re being processed at the PHSF,” said Ryan Boehmer, launch site integration manager with the Launch Services Program at NASA Kennedy. “One of the biggest sources of contamination for a spacecraft is people.”
The PHSF is a clean work area, so the facility must be free of any contamination that could negatively impact the Roman spacecraft. Technicians must dress in a protective suit before using the air shower, which sprays air to reduce any particles carried on clothing or equipment and keeps the spacecraft’s environment in the facility as clean and contamination-free as possible.
Dust, debris, or even a piece of hair can interfere with a spacecraft and its instruments as it gathers crucial science data in orbit. The facility is certified to the International Organization for Standardization (ISO) ISO class 8 clean room standards but can exceed that with augmentation. The team is planning to use a HEPA filtration wall to achieve ISO class 7 standards required for Roman.
Another PHSF upgrade is its HVAC system, which is far more advanced than a typical residential system. The goal of this upgrade is to replace the facility’s chiller coils to ensure the airlock and clean room remain climate-controlled with backups available if one fails. Additional updates include the compressed-air system’s pressure tank, air dryer, and regulator panel to supply clean, reliable compressed air to slide hardware around the floor – like an air hockey table but on a much larger scale. Massive volumes of filtered air circulate through the facility to prevent outside contaminants from entering the building.
“Another consideration we have is keeping both the spacecraft and people working on it at comfortable temperatures during processing, especially given Florida’s hot and humid environment,” said Genevieve Futch, Launch Services Program mission manager for Roman at NASA Kennedy. “Throughout processing, teams are powering on spacecraft for testing, which can generate heat. All the technicians in the clean room wear significant amounts of protective garments that trap heat, so we rely on the PHSF’s HVAC to reliably maintain the facility’s environment. We don’t want to overheat either the hardware or our team.”
Inside, the temperature is kept around 70° F with a maximum relative humidity of 60% and minimum humidity requirement of 30%. Too much humidity can lead to corrosion, while too little can create static electricity. The team constantly monitors the conditions to ensure the spacecraft’s safety.
Workers also repainted the facility’s 15-ton bridge crane, which is used to lift spacecraft hardware, but not for aesthetic reasons. The new paint helps prevent any paint chips from becoming foreign object debris, commonly referred to as FOD. All the teams working on Roman aim to mitigate even microscopic particles from contaminating the spacecraft. Paint chips are larger and heavier than some of the smallest contaminants, but they could still become airborne debris that can settle on hardware, causing mechanical interference and degrading performance. Removing all potential sources of contamination is part of the launch site planning and reflects the attention to detail required to launch a spacecraft.
Roman will undergo several prelaunch operations, including thermal protection closeout, cleaning, solar array work, and loading hydrazine propellant. The PHSF is one of the very few facilities where spacecraft undergo both hazardous fueling operations and delicate contamination control procedures.
The PHSF began operations in 1986 during the Space Shuttle Program, where it supported processing for several major shuttle payloads, including missions supporting NASA’s Hubble Space Telescope. Since 1998, the Launch Services Program has managed 16 launches processed at the PHSF, beginning with the program’s first mission, NASA’s Deep Space 1. Other missions include Mars 2020 Perseverance Rover, NASA’s Europa Clipper spacecraft, and soon to be Roman.
“We have the responsibility for ensuring the highest practical probability of launch success for these incredibly sophisticated and delicate spacecrafts,” said Boehmer. “We’re a common thread combining the capabilities of commercial rockets with NASA’s scientific spacecraft, and we have experience supporting the processing of everything from space telescopes to Mars rovers to deep space probes in this building.”
Roman will work in collaboration with NASA’s James Webb Space Telescope and Hubble. It is a survey mission with a field of view 100 times larger than Webb and up to 200 times larger than Hubble. Roman’s wide view will help answer essential questions about dark energy, exoplanets, and astrophysics, while Webb can follow up on rare objects Roman discovers, looking at them in greater detail.
“I think it’s human nature to wonder about what is out there in space,” said Boehmer. “I believe when we start getting images from Roman and see more of the universe than ever before, people will connect to that feeling of wonder.”

The Hashemite Kingdom of Jordan signed the Artemis Accords Thursday during a ceremony hosted by NASA at the agency’s headquarters in Washington, becoming the latest nation to commit to responsible space exploration to benefit humanity.
“It is my privilege to welcome Jordan as the newest signatory to the Artemis Accords,” said NASA Administrator Jared Isaacman. “By signing the accords today, Jordan brings valuable perspective and capabilities that will help expand the Golden Age of exploration for all mankind. They join at a pivotal moment, as we take the accords principles and put them into practice with humanity’s return to the Moon. Through Artemis, we’re going back to the lunar surface, with contributions from our international partners, to build a Moon Base and to stay.”
Ambassador Dina Kawar of Jordan signed the accords on behalf of the country. U.S. Department of State Acting Principal Deputy Assistant Secretary for Oceans and International Environmental and Scientific Affairs Ruth Perry also participated in the ceremony.
“Jordan has more engineers per capita than almost any country in the world,” said Kawar. “Through the National Council for Future Technologies, His Royal Highness Crown Prince Al Hussein is ensuring that talent has a direction, transforming Jordan into a regional and global technology hub across AI, digital infrastructure, advanced manufacturing, and now space. Today’s signing is proof that this ambition has no ceiling. We invite our American partners to build what comes next with us.”
In 2018, Jordan launched the JY1 satellite, a CubeSat developed by university students. The CubeSat transmitted images and audio from orbit after its launch on a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California. Jordan’s growing interest in space includes a privately operated analog research facility in Wadi Rum, where the Jordan Space Research Initiative conducted its PETRA1 and PETRA2 missions in 2024 and 2025 to advance human spaceflight and planetary research for real-world benefits on Earth.
In 2020, during the first Trump Administration, the United States, led by NASA and the State Department, joined with seven other founding nations to establish the Artemis Accords, responding to the growing interest in lunar activities by both governments and private companies. The accords introduced the first set of practical principles aimed at enhancing the safety and coordination between like-minded nations as they explore the Moon, Mars, and beyond.
Signing the Artemis Accords means committing to explore peaceably and transparently, to render aid to those in need, to enable access to scientific data that all of humanity can learn from, to ensure activities do not interfere with those of others, and to preserve historically significant sites and artifacts by developing best practices for space exploration for the benefit of all.
More countries are expected to sign the Artemis Accords in the months and years ahead, as NASA continues its work to establish a safe, peaceful, and prosperous future in space.
