Robotic Arm Gets a Workout

A new robotic arm for assembling spacecraft and exploration platforms in space flexed its muscle in a successful ground demonstration Jan. 19.

The device, called the Tension Actuated in Space MANipulator (TALISMAN) was tested in the Structures and Materials Test Laboratory at NASA’s Langley Research Center in Hampton, Virginia.

TALISMAN is just one component of the Commercial Infrastructure for Robotic Assembly and Servicing (CIRAS). In this demonstration, the team manipulated the newer, longer arm back and forth from folded to extended positions to demonstrate that it is fully operational and ready for more comprehensive testing.  

“The demonstration we accomplished last week was the rough equivalent of what the Navy calls a “shakedown cruise,” said John Dorsey, NASA principal investigator for CIRAS.

The tests will get progressively more difficult over the coming months as more detailed tasks are demanded of the robots. Future tests include not only a series of demonstrations exercising TALISMAN’s ability to move and manipulate objects along a truss, but also a demonstration of the NASA Intelligent Jigging and Assembly Robot (NINJAR) and the Strut Assembly, Manufacturing, Utility & Robotic Aid (SAMURAI) building two truss bays from pieces.

CIRAS is a collaboration with industry partner Orbital ATK of Dulles, Virginia, aimed at developing a “toolbox” of capabilities for use in servicing, refueling, and ultimately the construction of assets on orbit.

Advanced in-space assembly technologies will provide a more cost-effective way to build spacecraft and future human exploration platforms in space, such as the tended spaceport between the Earth and the Moon the agency is looking to build that would serve as a gateway to deep space and the lunar surface.

One of the biggest benefits of in-space assembly is the ability to launch the necessary material and components in tightly packed envelopes, given rockets have limited capacity with strict requirements on the size and shape of pre-assembled items being launched into orbit.

“It’s the difference between taking your new bedroom suite home in a box from IKEA using your Honda Civic and hiring a large box truck to deliver the same thing that was fully assembled at a factory. Space is a premium on launches,” said Chuck Taylor, CIRAS project manager at Langley.

Being able to build and assemble components in space will allow more affordable and more frequent science and discovery missions in Earth orbit, across the solar system and beyond.

CIRAS is made up of several components. TALISMAN, the long-reach robotic arm technology, was developed and patented at Langley. TALISMAN moves SAMURAI, which is like the hand that brings truss segments to NINJAR, the robotic jig that holds the truss segments in place perfectly at 90 degrees while they are permanently fastened using electron beam welding to join together 3D printed titanium truss corner joints to titanium fittings at the strut ends. NINJAR was built almost entirely by interns in the lab. The students have done incredible things, Taylor said.

“We couldn't have done what we’ve done without them,” he added.

CIRAS is a part of the In-Space Robotic Manufacturing and Assembly project portfolio, managed by NASA’s Technology Demonstration Missions Program and sponsored by NASA’s Space Technology Mission Directorate.

The CIRAS team includes prime contractor Orbital ATK, supported by its wholly-owned subsidiary, Space Logistics, LLC; along with NASA Langley; NASA’s Glenn Research Center in Cleveland, Ohio; NASA’s Goddard Space Flight Center in Greenbelt, Maryland; and the U.S. Naval Research Laboratory in Washington, D.C. If Orbital and Langley are successful in this spring’s series of demonstrations, they may be awarded a second contract to demonstrate these same capabilities on orbit.

Katherine Johnson Biography

https://www.nasa.gov/content/katherine-johnson-biography

Date of Birth: August 26, 1918 Hometown: White Sulphur Springs, WV Education: B.S., Mathematics and French, West Virginia State College, 1937 Hired by NACA: June 1953 Retired from NASA: 1986 Actress Playing Role in Hidden Figures: Taraji P. Henson

Being handpicked to be one of three black students to integrate West Virginia’s graduate schools is something that many people would consider one of their life’s most notable moments, but it’s just one of several breakthroughs that have marked Katherine Johnson’s long and remarkable life. Born in White Sulphur Springs, West Virginia in 1918, Katherine Johnson’s intense curiosity and brilliance with numbers vaulted her ahead several grades in school. By thirteen, she was attending the high school on the campus of historically black West Virginia State College. At eighteen, she enrolled in the college itself, where she made quick work of the school’s math curriculum and found a mentor in math professor W. W. Schieffelin Claytor, the third African American to earn a PhD in Mathematics. Katherine graduated with highest honors in 1937 and took a job teaching at a black public school in Virginia.  

When West Virginia decided to quietly integrate its graduate schools in 1939, West Virginia State’s president Dr. John W. Davis selected Katherine and two male students as the first black students to be offered spots at the state’s flagship school, West Virginia University. Katherine left her teaching job, and enrolled in the graduate math program. At the end of the first session, however, she decided to leave school to start a family with her husband.  She returned to teaching when her three daughters got older, but it wasn’t until 1952 that a relative told her about open positions at the all-black West Area Computing section at the National Advisory Committee for Aeronautics’ (NACA’s) Langley laboratory, headed by fellow West Virginian Dorothy Vaughan. Katherine and her husband, James Goble, decided to move the family to Newport News to pursue the opportunity, and Katherine began work at Langley in the summer of 1953. Just two weeks into Katherine’s tenure in the office, Dorothy Vaughan assigned her to a project in the Maneuver Loads Branch of the Flight Research Division, and Katherine’s temporary position soon became permanent. She spent the next four years analyzing data from flight test, and worked on the investigation of a plane crash caused by wake turbulence. As she was wrapping up this work her husband died of cancer in December 1956.

The 1957 launch of the Soviet satellite Sputnik changed history—and Katherine Johnson’s life. In 1957, Katherine provided some of the math for the 1958 document Notes on Space Technology, a compendium of a series of 1958 lectures given by engineers in the Flight Research Division and the Pilotless Aircraft Research Division (PARD). Engineers from those groups formed the core of the Space Task Group, the NACA’s first official foray into space travel, and Katherine, who had worked with many of them since coming to Langley, “came along with the program” as the NACA became NASA later that year. She did trajectory analysis for Alan Shepard’s May 1961 mission Freedom 7, America’s first human spaceflight. In 1960, she and engineer Ted Skopinski coauthored Determination of Azimuth Angle at Burnout for Placing a Satellite Over a Selected Earth Position, a report laying out the equations describing an orbital spaceflight in which the landing position of the spacecraft is specified. It was the first time a woman in the Flight Research Division had received credit as an author of a research report.

In 1962, as NASA prepared for the orbital mission of John Glenn, Katherine Johnson was called upon to do the work that she would become most known for. The complexity of the orbital flight had required the construction of a worldwide communications network, linking tracking stations around the world to IBM computers in Washington, DC, Cape Canaveral, and Bermuda. The computers had been programmed with the orbital equations that would control the trajectory of the capsule in Glenn’s Friendship 7 mission, from blast off to splashdown, but the astronauts were wary of putting their lives in the care of the electronic calculating machines, which were prone to hiccups and blackouts. As a part of the preflight checklist, Glenn asked engineers to “get the girl”—Katherine Johnson—to run the same numbers through the same equations that had been programmed into the computer, but by hand, on her desktop mechanical calculating machine.  “If she says they’re good,’” Katherine Johnson remembers the astronaut saying, “then I’m ready to go.” Glenn’s flight was a success, and marked a turning point in the competition between the United States and the Soviet Union in space.

When asked to name her greatest contribution to space exploration, Katherine Johnson talks about the calculations that helped synch Project Apollo’s Lunar Lander with the moon-orbiting Command and Service Module. She also worked on the Space Shuttle and the Earth Resources Satellite, and authored or coauthored 26 research reports. She retired in 1986, after thirty-three years at Langley. “I loved going to work every single day,” she says. In 2015, at age 97, Katherine Johnson added another extraordinary achievement to her long list: President Obama awarded her the Presidential Medal of Freedom, America’s highest civilian honor.

Thanks for the shoutout!

I will be taking a short photography break to attend to a few long-neglected projects. I’ll be back with bone-yard pictures in time for Halloween, or sooner if something interesting crops up first.

Until then, here’s a completely irrelevant parting shot of the vacuum chambers on a hypersonic aeroelasticity wind tunnel at NASA’s Langley Research Center in Hampton, Virginia. Later, y'all. 

The Future of Monitoring Air Quality from Space

TEMPO’s measurements from geostationary orbit (GEO) will create a revolutionary dataset that provides understanding and improves prediction of air quality (AQ) and climate forcing.

The KORUS-AQ airborne science experiment taking to the field in South Korea this spring is part of a long-term, international project to take air quality observations from space to the next level and better inform decisions on how to protect the air we breathe.

Before a new generation of satellite sensors settle into orbit, field missions like KORUS-AQ provide opportunities to test and improve the instruments using simulators that measure above and below aircraft, while helping to infer what people breathe at the surface.

“We want to move beyond forecasting air pollution, we want to influence strategies to improve it,” said Jim Crawford, a lead scientist at NASA’s Langley Research Center in Hampton, Virginia. “This is where satellite observations can play an important role.”

Existing low Earth orbit (LEO) instruments have established the benefit of space-based views of air pollution. From space, large areas can be viewed consistently, whereas from the ground only discrete (often single) points can be measured. As Dave Flittner, TEMPO project scientist, explains, a geostationary (GEO) air-quality constellation can accurately track the import and export of air pollution as it is transported by large-scale weather patterns.

TEMPO, or Tropospheric Emissions: Monitoring of Pollution, is one instrument on the road to improving air quality from space. According to Flittner, hardware has recently begun development and TEMPO is on track to be finished no later than fall of 2017, and available for launch on a to be selected commercial communications satellite.

For the first time, TEMPO will make accurate hourly daytime measurements of tropospheric pollutants (specifically ozone, nitrogen dioxide, sulfur dioxide, formaldehyde, and aerosols) with high resolution over the U.S., Canada and Mexico. With help from related international missions, these observations provide a complete picture of pollution sources in the northern hemisphere and how they influence air quality from local to global scales.

These geostationary instruments will make up a northern hemisphere air quality constellation to analyze their respective regions.

About 22,000 miles above the equator, the Korean Aerospace Research Institute’s GEMS (The Geostationary Environmental Monitoring Spectrometer), the European Space Agency’s Sentinel-4/UVN, and NASA’s TEMPO, will maintain their positions in orbit as the Earth rotates, covering a majority of the area from East Asia through greater North America and Europe. Together, these instruments will make up a northern hemisphere air quality constellation.. All three of these instruments analyze the same pollutant concentrations in their respective region, from the morning to evening.

Another critical part of the global air quality constellation are the LEO instruments, such as TROPOMI (a.k.a. Sentinel-5P), which will launch in late 2016 and provide a common reference for the three GEO sensors, allowing for a more accurate assessment of air quality within each region.

Museum Exhibit Reveals the NASA Langley Human Computers from "Hidden Figures"

Sam McDonald NASA Langley Research Center

A new display at the Hampton History Museum offers another view of African-American women whose mathematical skills helped the nation’s early space program soar.

“When the Computer Wore a Skirt: NASA’s Human Computers” opens to the public Saturday, Jan. 21, and focuses on three women — Dorothy Vaughan, Mary Jackson and Katherine Johnson — who were illuminated in Margot Lee Shetterly’s book “Hidden Figures” and the major motion picture of the same name. Located in the museum's 20th century gallery, it was created with support from the Hampton Convention and Visitor Bureau and assistance from NASA's Langley Research Center.

“Langley’s West Computers were helping America dominate aeronautics, space research, and computer technology, carving out a place for themselves as female mathematicians who were also black, black mathematicians who were also female,” Shetterly wrote.

The modestly sized exhibit is comprised of four panels with photos and text along with one display case containing artifacts, including a 1957 model Friden mechanical calculator. That piece of equipment represented state-of-the-art technology when then original human computers were crunching numbers. A three-minute video profiling Johnson —a Presidential Medal of Freedom winner — is also part of the exhibit.

A display case at left contains a 1957 Friden STW-10 mechanical calculator, the type used by NASA human computers including Katherine Johnson. "If you were doing complicated computations during that time, this is what you used," said Hampton History Museum Curator Allen Hoilman. The machine weighs 40 pounds.

Museum curator Allen Hoilman said his favorite artifact is a May 5, 1958 memo from Associate Director Floyd Thompson dissolving the West Area Computers Unit and reassigning its staff members to other jobs around the center.

“It meant that the segregated work environment was coming to an end,” Hoilman said. “That’s why this is a significant document. It’s one of the bookends.”

That document, along with several others, was loaned to the museum by Ann Vaughan Hammond, daughter of Dorothy Vaughan. Hoilman said family members of other human computers have been contacted about contributing artifacts as well.

Ann Vaughan Hammond worked hard to find meaningful items for the display. “She really had to do some digging through the family papers,” Hoilman said, explaining that the women who worked as human computers were typically humble about their contributions. They didn’t save many mementos.

“They never would have guessed they would be movie stars,” Hoilman said.

Tiny NASA Cameras to Watch Commercial Lander form Craters on Moon

Footage from vibration and thermal vacuum testing of the SCALPSS cameras and data storage unit.

This little black camera looks like something out of a spy movie — the kind of device one might use to snap discrete photos of confidential documents.

It's about half the size of a computer mouse.

But the only spying this camera — four of them, actually — will do is for NASA researchers wondering what happens under a spacecraft as it lands on the Moon.

It's a tiny technology with a big name — Stereo Camera for Lunar Plume-Surface Studies, or SCALPSS for short — and it will journey to the Moon in 2021 as a payload aboard an Intuitive Machines Nova-C lunar lander spacecraft. Intuitive Machines is one of two U.S. companies delivering technology and science experiments to the lunar surface later this year as part of NASA's Commercial Lunar Payload Services (CLPS) initiative. SCALPSS will provide important data about the crater formed by the rocket plume of the lander as it makes its final descent and landing on the Moon's surface.

As part of the Artemis program, NASA will send robots and humans to study more of the Moon than ever before. The agency plans to establish sustainable lunar exploration by the end of the decade, and has outlined its Artemis Base Camp concept for the lunar South Pole. Landers may deliver multiple payloads very near one another. Data such as that from SCALPSS will prove aid in computer models that inform subsequent landings.

"As we send bigger, heavier payloads and we try to land things in close proximity to each other, first at the Moon then at Mars, this ability to predict landing impacts is very important," said Michelle Munk, principal investigator for SCALPSS at NASA's Langley Research Center in Hampton, Virginia.

The four SCALPSS cameras, which will be placed around the base of the commercial lander, will begin monitoring crater formation from the precise moment a lander's hot engine plume begins to interact with the Moon's surface.

"If you don't see the crater when it starts to form, you can't really model it," said Munk. "You've got to have the start point and the end point and then you can figure out what happened, in between."

The cameras will continue capturing images until after the landing is complete. Those final stereo images, which will be stored on a small onboard data storage unit before being sent to the lander for downlink back to Earth, will allow researchers to reconstruct the crater's ultimate shape and volume.

Testing to characterize the SCALPSS camera and lens took place last year at NASA's Marshall Space Flight Center in Huntsville, Alabama. Researchers conducted radial distortion, field-of-view and depth-of-focus tests among others. They also ran analytical models to better characterize how the cameras will perform. Development of the actual SCALPSS payload took place at Langley. And over the summer, researchers were able to enter the lab to assemble the payload and conduct thermal vacuum and vibration tests.

That lab access involves special approval from officials at Langley, which is currently only giving access to essential employees and high-priority projects to keep employees safe during the ongoing COVID-19 pandemic. SCALPSS was one of the first projects to return to the center. Before they could do that, facilities had to pass safety and hazard assessments. And while on center, the team had to follow strict COVID-19 safety measures, such as wearing masks and limiting the number of people who could be in a room at one time. The center also provided ample access to personal protective equipment and hand sanitizer.

The SCALPSS hardware was completed in late October and will be delivered to Intuitive Machines in February.

"Development and testing for the project moved at a pretty brisk pace with very limited funds," said Robert Maddock, SCALPSS project manager. "This was likely one of the most challenging projects anyone on the team has ever worked on."

But Munk, Maddock and the entire project team have embraced these challenges because they know the images these little cameras collect may have big ripple effects as NASA prepares for a human return to the Moon as part of the Artemis program.

"To be able to get flight data and update models and influence other designs — it's really motivating and rewarding," said Munk.

Hot off the heels of this project, the SCALPSS team has already begun development of a second payload called SCALPSS 1.1. It will be flown by another CLPS commercial lander provider to a non-polar region of the Moon in 2023 and collect data similar to its predecessor. It will also carry two additional cameras to get higher resolution stereo images of the landing area before engine plume interactions begin, which is critical for the analytic models in establishing the initial conditions for the interactions.

NASA’s Artemis program includes sending a suite of new science instruments and technology demonstrations to study the Moon, landing the first woman and next man on the lunar surface in 2024, and establishing a sustained presence by the end of the decade. The agency will leverage its Artemis experience and technologies to prepare for humanity’s the next giant leap – sending astronauts to Mars as early as the 2030s.
