During a ceremony hosted by NASA Administrator Jared Isaacman at the agency’s headquarters in Washington on Monday, the Republic of Türkiye signed the Artemis Accords, joining the growing international coalition of like-minded nations dedicated to peaceful, transparent space exploration.
“It is my privilege to welcome the Republic of Türkiye as the 71st signatory of the Artemis Accords,” said Isaacman. “Last year, President Trump directed NASA to accelerate its return to the lunar surface and establish humanity’s first enduring presence on another world, a Moon Base, as well as lay the foundation for the manned exploration of Mars. NASA never undertakes these grand endeavors alone. On the Moon Base, we’re taking the Artemis Accords principles and putting them into practice on the lunar surface. NASA has invited every signatory to take part in this endeavor, creating opportunities for nations to contribute major pieces of hardware, scientific payloads, technology demonstrations, CubeSats, and other capabilities to future Artemis missions.”
Turkish Minister of Industry and Technology Mehmet Fatih Kacır signed on behalf of Türkiye. The President of the Turkish Space Agency Yusuf Kıraç, and the U.S. Deputy Assistant Secretary of State for Space and Environment Connor Tomlinson, also participated in the event.
Türkiye’s recent achievements in human spaceflight underscore its commitment to space exploration. In 2024, the country’s first astronaut, Alper Gezervaci, traveled to the International Space Station on Axiom Mission 3 and conducted scientific research alongside NASA astronauts. That same year, a second Turkish astronaut, Tuva Atasever, flew on Virgin Galactic 07 suborbital mission, conducting experiments and physiology research.
Türkiye will soon launch its first lunar mission, AYAP-1, joining the small but growing group of countries building and launching their own satellites to the Moon.
The country’s signing also comes as the country prepares to host the International Astronautical Congress in Antalya this October. Dozens of Artemis Accords signatories are expected to attend to discuss the future of peaceful and transparent space exploration.
In 2020, 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. They introduced the first set of practical principles aimed at enhancing the safety and coordination between nations as they explore the Moon, Mars, and beyond, committing nations to:
By signing the Artemis Accords, nations open the door to opportunities for future lunar exploration with NASA, advancing humanity’s return to the Moon, and shaping the Golden Age of space exploration and innovation.

Every month, NASA Earth Observatory features a puzzling satellite image. The September 2026 puzzler appears above.
Your Challenge
Identify the location shown in this satellite image. Share what clues you see, where you think it is, and what makes this place interesting or unique to you.
How to Answer
Submit your response using this form and select “Puzzler Answer” as the topic. Please include your preferred name or alias.
You can keep it simple and just guess the location. Want to impress us? Tell us which satellite and instrument captured the image, which spectral bands were used, or point out a subtle detail about the geology or history of the area. If something catches your eye, or if this is your home or means something to you, we’d love to hear about it.
The Prize
We can’t offer prize money or a trip to space to see Earth like satellites and astronauts do. But we can offer something almost as rewarding: puzzler bragging rights.
About a week after the challenge, we’ll post the answer at the top of this page, along with a link to an Earth Observatory Image of the Day story that explains the image in more detail. We’ll recognize the first person who correctly guesses the location, and we may also highlight readers who share especially thoughtful or interesting answers. By submitting a response, you acknowledge that your comments may be edited, excerpted, and published on this page.
Until then, zoom in, look closely, and enjoy the challenge. See you at the reveal!

NASA’s Nancy Grace Roman Space Telescope, aboard a SpaceX Falcon Heavy rocket, transits the Sun during launch from the agency’s Kennedy Space Center in Florida on Aug. 30, 2026. Roman is named after the agency’s first chief astronomer.
Roman will survey billions of stars and galaxies with a field of view far larger than Hubble’s, helping scientists study dark energy, exoplanets, and the evolution of the universe.
Follow along with Roman’s journey.

Roman is making its three-month journey from Earth to Sun-Earth Lagrange Point 2, or L2. Along the way, Roman is undergoing a process called commissioning, where systems are turned on, adjusted, calibrated, and prepared for science operations. Commissioning is the time for scientists and engineers to make sure that Roman is performing as expected. The schedule is subject to change as the team assesses and adjusts as needed.
An hour and 23 minutes after launch, Roman began to emerge from the tight configuration that allowed it to fit in the rocket fairing. The solar panels and sunshade deployed, shading the rest of the observatory and providing power to the systems. Within the upcoming days, the antenna will swing out and the visor-like deployable aperture cover will move into place to permanently reveal and shade the primary mirror.
This visualization shows the stable, halo orbit that Roman will have around L2. At this location, the gravity of the Sun and Earth, together with an object’s motion around the Sun, let it stay lined up with Earth as they orbit, allowing Roman to have a relatively steady orbit without using much fuel. This location also offers exceptionally stable optical performance and a constant, unobstructed view of a wide swath of the sky; Earth won’t block much of Roman’s view since it will be so distant. And at L2, heat from Earth, the Sun, and the Moon have less effect on infrared telescopes, which “see” heat.

APOD
Astronomy Picture of the Day
Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.
Explanation: A new telescope has been launched into space to study the universe. The Nancy Grace Roman Space Telescope (RST) has the same size main mirror as the Hubble Space Telescope (HST) but sees 100 times more sky during each snapshot. This is possible because when compared to HST, RST’s main mirror is more curved, its secondary mirror is closer, and its main camera is larger. The result is that RST can inspect more of the sky more quickly, likely allowing, among other capabilities, the discovery of many more supernovas which tell us more about the expansion rate and composition of our universe, and many more planets orbiting other stars that tell us more about the possibilities for life elsewhere in the universe. RST will orbit the Sun, not the Earth, like the James Webb Space Telescope. The featured video shows Roman being launched yesterday from Kennedy Space Center, Florida, USA aboard a SpaceX Falcon Heavy rocket.
