Turning Vanes inside the Altitude Wind Tunnel

Turning Vanes inside the Altitude Wind Tunnel

Two men wearing hats and long coats stand at the bottom of a massive circular tunnel. At the end of the tunnel is four rows of stacked panels: this are the turning vanes. In the middle of the rows, there is a dark, cylindrical shaft that connects to the tunnel walls. This image is in black and white.

Men stand in front of turning vanes inside the Altitude Wind Tunnel (AWT) at the National Advisory Committee for Aeronautics Aircraft Engine Research Laboratory in this February 1944 publicity photo. The photo was taken just weeks after the tunnel became operational.

The AWT was the only wind tunnel capable of testing full-size aircraft engines in simulated altitude conditions. A large wooden drive fan, located on the other side of these vanes, created wind speeds up to 500 miles per hour. Each corner of the rectangular tunnel had turning vanes, which straightened the airflow and directed it around the corners. This set of vanes was in the 31-foot-diameter southeast corner of the tunnel. These elliptical panels consisted of 36 to 42 vertical vanes that were supported by three horizontal supports. The individual vanes were 2.5 feet long and half-moon shaped. Each set of vanes took weeks to assemble before they were installed during the summer of 1943.

The Aircraft Engine Research Laboratory went through several name updates and changes through NACA and NASA history; it is now NASA’s Glenn Research Center in Cleveland.

Sols 4493-4494: Just Looking Around

A grayscale photograph of the Martian surface from the Curiosity rover captures medium gray soil in front of the rover, wavy in some areas, as if sculpted by wind or water, with rocks everywhere protruding up through it. They are lighter-toned than the ground, some rounded, others looking like cracked, smooth plates. One larger, rounded, light-colored rock stands out, in the center of the image. A part of the rover is visible in the frame, at bottom center.
NASA’s Mars rover Curiosity acquired this image using its Left Navigation Camera on March 25, 2025 — sol 4491, or Martian day 4,491 of the Mars Science Laboratory mission — at 17:16:50 UTC.

Earth planning date: Wednesday, March 26, 2025

It’s my second shift of the week as the Environmental theme lead and keeper of the plan (a bit of a mouthful we shorten to ESTLK) and today started out feeling eerily similar to Monday. Once again, Curiosity is posing like a geologist, which means that once again we can’t unstow the arm and will be skipping contact science. The silver lining is that this means we have extra time to have a good look around.

The plan also looks similar to Monday’s — targeted remote sensing on the first sol before driving away, and then untargeted remote sensing on the next. On sol 4493 we start our remote sensing, almost as remote as we can get, with a suprahorizon movie looking for clouds in the south. A dust-devil survey rounds out the sol’s environmental observations, and then the geology theme group can get down to the serious business of looking at rocks. For Mastcam this means observing a group of bedrock targets all called “Observatory Trail” (one of which you can see in the middle of the image above), pointing out some interesting veins in “Point Loma,” and casting their gaze out toward “Black Butte” (which I could not think of a fun pun for…). ChemCam has a LIBS observation of “Cholla,” as well as two long-distance observations of the Texoli Butte and the boxwork structures. Our second sol is a little more restrained, as untargeted sols tend to be. But Curiosity will still have plenty of energy after a good rest. We’re taking advantage of that with an extra-long dust-devil movie. Even though we’re in our cloudy season, we still sometimes see dust lifting, and having that extra time to look out for it increases our chances of catching a wind gust or a dust devil in action. Alongside that we also have a Mastcam tau observation to keep an eye on the amount of dust in the atmosphere, and wrap up with a ChemCam AEGIS activity to autonomously choose a LIBS target.

Cygnus Departs Station After Release from Robotic Arm

Cygnus Departs Station After Release from Robotic Arm

The Cygnus cargo craft departs the International Space Station as both spacecraft orited above the Atlantic Ocean.
The Cygnus spacecraft, with its prominent cymbal-shaped UltraFlex solar arrays, departs the International Space Station as both spacecraft orbited above the Atlantic Ocean.

At 6:55 a.m. EDT, the S.S. Richard “Dick” Scobee Northrop Grumman Cygnus spacecraft was released from the Canadarm2 robotic arm, which earlier detached Cygnus from the Earth-facing port of the International Space Station’s Unity module. At the time of release, the station was flying about 260 miles over the Pacific Ocean. 

The Cygnus spacecraft successfully departed the space station more than seven and a half months after arriving at the microgravity laboratory to deliver about 8,200 pounds of supplies, scientific investigations, commercial products, hardware, and other cargo for NASA. 

Following a deorbit engine firing on Sunday, March 30, Cygnus will begin a planned destructive re-entry, in which the spacecraft – filled with trash packed by the station crew – will safely burn up in Earth’s atmosphere. 

Cygnus arrived at the space station Aug. 6, 2024, following a launch on a SpaceX Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida. It was the company’s 21st commercial resupply services mission to the space station for NASA. The spacecraft is named the S.S. Richard “Dick” Scobee in honor of the former NASA astronaut.

Live coverage of the departure of the S.S. Richard “Dick” Scobee Northrop Grumman’s uncrewed Cygnus cargo spacecraft from the International Space Station is underway on NASA+, with its release from the robotic arm scheduled for 6:55 a.m. EDT. Coverage will conclude following departure from station.

Flight controllers on the ground sent commands earlier Friday morning for the space station’s Canadarm2 robotic arm to detach Cygnus from the Unity module’s Earth-facing port and then maneuvered the spacecraft into position for its release. NASA astronaut Nichole Ayers will monitor Cygnus’ systems during its departure from the space station.

After a deorbit engine firing on Sunday, March 30, Cygnus will begin a planned destructive re-entry, in which the spacecraft – filled with trash packed by the station crew – will safely burn up in Earth’s atmosphere.

Cygnus arrived at the space station Aug. 6, 2024, following a launch on a SpaceX Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida. It was the company’s 21st commercial resupply services mission to the space station for NASA. The spacecraft is named the S.S. Richard “Dick” Scobee in honor of the former NASA astronaut.

NASA Employee Meets Success at NASA Stennis

NASA Employee Meets Success at NASA Stennis

Rebecca Mataya stands for a portrait wearing a black jacket; Stennis posters are shown in the background
Rebecca Mataya is a budget analyst at NASA’s Stennis Space Center. “Whether you are an engineer, analyst, lawyer, technician, communicator or innovator, there is a place for you here at NASA,” she said. “Every skill contributes to the greater mission of pushing the boundaries of exploration, discovery, and progress. If you have a passion, determination, and willingness to learn, NASA is a place where you can grow and leave a lasting impact on the future of space.”
NASA/Stennis

A career path can unfold in unexpected ways. Ask NASA’s Rebecca Mataya.

The journey to NASA’s Stennis Space Center near Bay St. Louis, Mississippi, was not planned but “meant to be,” she said.

While working for a local business, the Picayune, Mississippi, native frequently delivered items to NASA Stennis. While making a delivery, Mataya noticed a construction worker who needed directions while waiting to receive a NASA Stennis visitor’s badge.

“I stepped in by offering a map and highlighting the way,” Mataya said.

This small moment of initiative caught the attention of the receptionist, who mentioned an opening at NASA Stennis. She noted that Mataya’s approach to the situation displayed the NASA Stennis culture of hospitality and a can-do attitude.

“The rest is history,” she said. “Looking back, it was not just about finding a job – it was about NASA Stennis finding me, and me discovering a place where I would build a fulfilling career.”

Since the first day of work when Mataya walked into NASA Stennis “in complete awe,” she has felt like every day is a learning experience filled with “wow” moments, like seeing a test stand up close and meeting rocket engineers. 

The Carriere, Mississippi, resident worked as a support contractor from 2008 to 2022, filling various roles from lead security support specialist to technical writer and program manager.

Her career path has progressed, where each role built upon the previous.

As a budget analyst in the NASA Stennis Office of the Chief Financial Officer since 2022, Mataya oversees the planning, programing, budgeting, and execution of funds for all Office of Strategic Infrastructure work within the NASA Stennis Center Operations Directorate. She also manages budgets for the NASA Stennis Construction of Facilities projects, and the congressionally approved Supplemental Funding portfolio.

“It is a role that requires adaptability, strategic thinking, and financial oversight,” she said. “I have cultivated these skills through years of experience, but more than that, it is a role that allows me to contribute something meaningful to the future of NASA and space exploration.”

Mataya will complete a master’s degree in Business Administration from Mississippi State University in May. She previously earned her bachelor’s degree from Mississippi State and an associate degree from Pearl River Community College. 

“My career has been shaped by growth and achievement, but the greatest highlight has always been the incredible people I have had the privilege of working with,” she said. “Walking the halls of NASA, where top leaders recognize me by name, is a testament to the trust and relationships I have built over the years.”

Mataya said supervisors have consistently entrusted her with more complex projects, confident in her ability to rise to the challenge and deliver results. As a result, she has had opportunities to mentor interns and early-career professionals, guiding them as others once guided her.

“Seeing my colleagues succeed and knowing they have reached their goals, and championing their progress along the way, remains one of the most rewarding aspects of my career,” she said.

Mataya knows from experience that NASA Stennis offers opportunity and a supportive environment, not only for employees looking for career growth, but to customers seeking world-class testing facilities. “NASA Stennis is a place where collaboration thrives,” she said. “It is where NASA, tenants, and commercial partners come together as one cohesive community with a culture of mutual respect, support, and an unwavering commitment to excellence. As America’s largest rocket propulsion test site, NASA Stennis is evolving, and I look forward to seeing how our technological advancements attract new commercial partners and expand NASA’s capabilities.”
