NASA Invites Media to Roman Space Telescope, Crew-13 Launches

Media accreditation now is open for the launch of NASA’s Nancy Grace Roman Space Telescope and the agency’s SpaceX Crew-13 missions, both targeting launch in the coming months.

The Roman telescope is slated to launch no earlier than 7:20 a.m. EDT Sunday, Aug. 30, aboard a SpaceX Falcon Heavy rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. The observatory, named after NASA’s first chief astronomer, will have a deep, panoramic view of the cosmos, generating never-before-seen pictures that will revolutionize our understanding of the universe.

Crew-13 is scheduled to launch no earlier than mid-September from Space Launch Complex 40 at Cape Canaveral Space Force Station. The mission will carry NASA astronauts Jessica Watkins and Luke Delaney, CSA (Canadian Space Agency) astronaut Joshua Kutryk, and Roscosmos cosmonaut Sergey Teteryatnikov to the International Space Station for a science and research expedition. This will be NASA’s 13th commercial crew rotation mission with SpaceX’s Falcon 9 rocket and Dragon spacecraft.

Media interested in attending either or both launches must apply by the following deadlines:

• International media without U.S. citizenship must apply by 11:59 p.m. on Sunday, July 26.
• U.S. media and U.S. citizens representing international media organizations must apply by 11:59 p.m. on Thursday, July 30.

All accreditation requests must be submitted online at:

https://media.ksc.nasa.gov

NASA’s Psyche Mission Images Details of Martian Surface During Flyby

Description

Captured by the multispectral imager instrument on NASA’s Psyche mission, this is an enhanced-color mosaic created from four individual images acquired on May 15, 2026, during the spacecraft’s flyby of Mars. 

Psyche was traveling from right to left (northeast to southwest on Mars) during the six minutes that it took to acquire the images for this mosaic, and the pixel scale resolution varies from 381 meters per pixel on the right to 440 meters per pixel on the left. The imager used its near-infrared, green, and blue filters, which helped to reveal highly contrasting craters, ridges, wind streaks, and volcanic plains materials on the surface.

The mosaic covers part of the Iapygia region of the rugged southern highlands of Mars, from approximately 62 degrees east to 78 degrees east longitude and 4 degrees north to 14 degrees south latitude. The largest crater, just below center, is called Fournier and is about 71 miles (114 kilometers) in diameter. The linear feature running from top to bottom of the mosaic just left of center is part of a long irregular cliff (or scarp) system called Oenotria Scopuli, which is part of the circular structure of the large Isidis impact basin to the northeast of this area.

NASA Welcomes Mauritius as 70th Artemis Accords Signatory  

The Republic of Mauritius has officially joined the global coalition committed to responsible space exploration, becoming the newest signatory and seventh African country to join the Artemis Accords. NASA’s Deputy Administrator Matt Anderson contributed video remarks for a signing ceremony on Friday, in the island nation’s city of Ébène.

“We are honored to welcome Mauritius to the Artemis Accords community and look forward to working together in the years ahead,” said Anderson. “Together, we are creating the foundation for future exploration while ensuring that space remains peaceful, accessible, and beneficial for all. America will return to the Moon and ignite the Golden Age of exploration and discovery. That work requires capable partners and a shared commitment to responsible exploration.”

Mauritius’ Permanent Secretary at the Ministry of Tertiary Education, Science and Research Navindsing Jugmohunsing signed the Artemis Accords on behalf of the country. U.S. Deputy Assistant Secretary of State for African Affairs Sarah Troutman and U.S. Chargé d’Affaires to Mauritius Craig Halbmaier were present to witness the signing.

“The accession of Mauritius to the Artemis Accords marks a defining chapter in our New Space journey,” said Jugmohunsing. “As a Small Island Developing State in the Indian Ocean, we are committed to ensuring that space serves humanity by protecting our oceans and coastlines and amplifying the voices of nations like ours. Mauritius stands ready to help shape the future of space governance while unlocking new opportunities for innovation and partnership.”

NASA first engaged with Mauritius through its early global mapping efforts, owing to the nation’s strategic location. Between 1965 and 1980, NASA used several satellite missions to collect global measurements of Earth’s size and shape. As part of that work, NASA sent teams to Mauritius and other international tracking stations that supported satellite photography for geodetic analysis. Their observations strengthened the navigation technologies used from Apollo to Artemis and helped lay the foundation for the partnership reaffirmed today by the Artemis Accords.

In 2020, NASA and the Department of State 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. They 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, committing nations to: 

• explore peaceably and transparently 
• render aid to those in need 
• enable access to scientific data  
• ensure activities do not interfere with those of others 
• preserve historically significant sites and artifacts by developing best practices 

Five years later, President Donald J. Trump’s National Space Policy directed NASA to establish a sustained lunar outpost. With this Moon Base, NASA is putting the principles of the Artemis Accords into practice, inviting every signatory including now Mauritius to take part in the endeavor. 

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.

A Tide-Fueled Trove of Biodiversity in Guinea-Bissau

Twice each day, tides ebb and flow through a maze of sandy channels, mudflats, and mangrove forests that flank the 88 islands and islets of Guinea-Bissau’s Bijagós Archipelago (Arquipélago dos Bijagós in Portuguese). Seen from above, the process leads to stark changes to the landscape: around low tide, intertidal mudflats and sandflats emerge from the sea, causing islands to grow significantly before shrinking again hours later.

The perpetual rhythm of the tides sustains outpourings of marine life in an archipelago that, as of 2025, was inscribed as a UNESCO World Heritage site. The site protects the only active deltaic archipelago on Africa’s Atlantic coast, a place where tides, river sediments, coastal upwelling, and coastal currents come together to shape unusually productive and biodiverse island ecosystems.  

UNESCO estimates that the islands support some 870,000 migratory shorebirds, making this one of the most important feeding areas for birds in West Africa along the East Atlantic Flyway. Hundreds of species of birds dine on a potpourri of marine worms, crustaceans, mollusks, and small fish found on mudflats exposed by low tides. During high tides, manatees, dolphins, and schools of fish move closer to the islands, pushing deeper into the mangrove forests that ring them, and tens of thousands of sea turtles swim inland to sandy beaches as they hunt for nesting sites.

A huge population of green sea turtles nests on the tiny island of Poilão, part of the João Vieira and Poilão Marine National Park. After hatching, young turtles make perilous nighttime dashes to the water, often pursued by crabs, lizards, and birds. Once they reach the water, baby sea turtles face an array of predators, including jacks, barracudas, groupers, and snappers that patrol shallow waters as well as tuna, mackerel, sharks, and rays in deeper waters. According to some estimates, less than 1 percent of green sea turtle hatchlings survive to adulthood. 

A 2025 analysis of the region’s tides explored why the archipelago has some of the largest tidal ranges in West Africa. The researchers concluded that the region’s wide, shallow shelf and the estuary’s geometry combine to create a tidal range of up to 7 meters (23 feet), compared to about 1 meter (3 feet) in many other parts of the West African coast. The scientists used altimetry data from the NASA/CNES TOPEX/Poseidon, Jason-1, and Jason-2 satellites to help validate their findings.
