Eyeing the Richat Structure

In a remote part of northern Mauritania on the Adrar Plateau lies a desert landscape rich in human history. This region of northwestern Africa is sprinkled with Paleolithic stone tools, Neolithic cave paintings, and the remains of medieval towns once used by caravans crossing the Sahara Desert.

When viewed from space, the landscape appears to be shaped most prominently by natural forces. Wind sculpted the seas of colorful sand dunes and scoured plateaus capped with dark desert pavement, while ancient flowing water carved valleys and networks of dried river channels.

But the region’s most eye-catching feature when seen from above is the Richat Structure—a large geologic formation made of concentric ridges on the eastern side of the plateau. French geographers first described the feature in the 1930s, calling it the Richat “buttonhole.” NASA astronauts Ed White and James McDivitt helped bring wider global attention to what became known as “The Eye of the Sahara” after photographing it during their history-making Gemini IV mission.

The 40-kilometer-wide (25-mile-wide) structure was initially thought to be an impact crater because large meteors can produce circular features on Earth’s surface. However, researchers later showed that it is actually a deeply eroded geologic dome formed by the uplift of rock above an underground intrusion of igneous material. Over time, differing erosion rates among rock types in the exposed upper dome led to the development of circular ridges known as cuestas. The orange and gray colors reflect differences in sedimentary and igneous rock types across the structure and the surrounding landscape.

I Am Artemis: Rebekah Tolatovicz

Listen to this audio excerpt from Rebekah Tolatovicz, a mechanical technician lead supporting the Orion spacecraft’s main contractor Lockheed Martin:

0:00 / 0:00

At NASA’s Kennedy Space Center in Florida, there is a fleet of Orion spacecraft in work, and Rebekah Tolatovicz’s hands have helped build each one. Tolatovicz works to build, integrate, and test the spacecraft used during the Artemis II test flight, as well as those designed to carry humanity to the Moon on future Artemis missions.

Tolatovicz is a mechanical technician lead for the Arctic Slope Regional Corporation, or ASRC Federal, supporting the Orion spacecraft’s main contractor Lockheed Martin. A typical day for Tolatovicz takes place inside NASA Kennedy’s Operations and Checkout Building, with Orion assembly and testing. Her work ranges from helping coordinate and lead technicians, to jumping into hands-on installations on components like hatches and engines, to collaborating with the engineering team.

“What I really like about the area that I’m in is we do so much,” said Tolatovicz. “From starting with the bare structure and installing giant parts and titanium pieces, to final integration where you’re installing the tiniest little components. I think that’s the coolest part. We don’t do just one technical thing — it’s all the technical things.”

Tolatovicz currently works on the Orion crew modules that could sustain the astronauts on future Artemis missions, and she played a large role in work on the Artemis II spacecraft that carried four astronauts on a mission around the Moon, splashing down April 10. This included testing, integration, and final installation and closeout before the spacecraft was prepared for fueling and stacking on the SLS (Space Launch System) rocket.

As Artemis II was the first crewed mission under NASA’s Artemis program, Tolatovicz recognized the impact of her work.

It's really vital to stress the importance of what we do and know nothing is minuscule. Everything matters. It's really important to pass that down on to the new hires and make sure that everybody has that perspective.”

Tolatovicz, who began as an intern with Lockheed Martin through Eastern Florida State College’s aerospace technician program, knows what it’s like to be a newcomer. She had been mentored by technicians who worked through the space shuttle era, which largely shaped her experience and outlook.

“At first I didn’t think I was going to make it,” said Tolatovicz. “But if you come in with a good attitude and want to learn — there’s so much you can learn from these guys, they have decades of knowledge to share. Once I got down on the floor and was working with them hands-on, I knew I could figure it out.”

Tolatovicz has been working on the Orion program for nine years. Since then, the Maine native has witnessed her work come to fruition on Orion’s uncrewed Artemis I test flight as well as the Artemis II mission around the Moon.

“It’s really amazing for me to be a part of NASA’s history and the next step,” said Tolatovicz. “I just really love my job, the team, and working through challenges. You don’t think about it when you’re putting things on, but then you get to tell somebody else that you installed the thrusters for the spacecraft, and you realize — man, that’s pretty cool.”

NASA Selects Voyager for Seventh Private Mission to Space Station

2026-04-15 20:36

NASA and Voyager Technologies have signed an order for the seventh private astronaut mission to the International Space Station, targeted to launch no earlier than 2028 from Florida.

This is the company’s first selection for a private astronaut mission to the orbiting laboratory, underscoring NASA’s ongoing investment in fostering a commercial space economy and expanding opportunities for private industry in low Earth orbit. 

“Private astronaut missions are accelerating the growth of new ideas, industries, and technologies that strengthen America’s presence in low Earth orbit and pave the way for what comes next,” said NASA Administrator Jared Isaacman. “With three providers now selected for private missions, NASA is doing everything we can to send more astronauts to space and ignite the orbital economy. Each new partner brings fresh capabilities that move us closer to a future with multiple commercially operated space stations and a vibrant, sustainable marketplace in low Earth orbit.”

The mission, named VOYG-1, is expected to spend as many as 14 days aboard the space station. A specific launch date will depend on overall spacecraft traffic at the orbital outpost and other planning considerations.

Voyager will submit four proposed crew members to NASA and its international partners for review. Once approved and confirmed, they will train with NASA, international partners, and the launch provider for their flight.

“This award reflects decades of partnership with NASA and validates our belief that the infrastructure being built in low Earth orbit today is the launchpad for humanity’s future in deep space,” said Dylan Taylor, chairman and CEO, Voyager. “From the International Space Station’s first commercial airlock to the seventh private astronaut mission, Voyager is committed to making American human spaceflight stronger, more capable, and more sustainable at every step of the journey.”

The company will purchase mission services from NASA, including crew consumables, cargo delivery, storage, and other in-orbit resources for daily use. NASA will purchase the capability to return scientific samples that must remain cold during transit back to Earth.

NASA made the selection from proposals received in response to its March 2025 NASA Research Announcement.

Missions aboard the International Space Station, including private astronaut missions, help advance scientific knowledge and demonstrate new technologies in the unique microgravity environment. These commercial efforts in low Earth orbit help develop capabilities and technologies that could support NASA’s long-term goals for missions beyond low Earth orbit, including deep space exploration to the Moon and eventually to Mars through the agency’s Artemis program.

Experiments and supplies bound for the International Space Station launched on April 11 as part of the agency’s Northrop Grumman Commercial Resupply Services 24 mission.

As part of the approximately 11,000 pounds cargo that lifted off inside the company’s Cygnus XL spacecraft, NASA’s CubeSat Launch Initiative (CSLI) launched six CubeSats built by U.S. educational institutions and non-profit organizations. These CubeSats are Coconut, Harvard Undergraduate CubeSat (HUCSat), Low Earth Orbit Platform for Aerospace Research and Development Satellite 1 (LEOPARDSat-1), and three Pleiades Rapid Orbital Verification Experiment System (PROVES) CubeSats: PROVES – Alcyone, PROVES – Atlas, and PROVES – Electra.

Each CubeSat is a small satellite that will deploy into orbit from the space station to conduct its experiments. NASA’s Launch Services Program, based at the agency’s Kennedy Space Center in Florida, manages CSLI and manifested these CubeSats on the mission as part of the Educational Launch of Nanosatellites (ELaNa) 58 launch grouping.
