Statement from NASA’s Jennifer Kunz at SpaceCom, 50th Space Congress

Jennifer Kunz, associate director technical of NASA’s Kennedy Space Center in Florida, released the following statement after speaking Thursday at the SpaceCom / 50th Space Congress in Orlando, Florida.

“NASA’s Moon to Mars strategy rests on three pillars: pursuing science to better understand the universe and our origins; inspiring the next generation to achieve the seemingly impossible; and building on American preeminence in science, technology and exploration while strengthening economic and diplomatic ties with other nations. Kennedy is proud to be at the forefront of helping achieve the agency’s ambitious Moon to Mars Objectives for the benefit of all.

“Most people know Kennedy for launching rockets, but our spaceport also is home to new technologies needed to establish a sustained human presence on the Moon and exploration throughout the solar system. Today, Kennedy teams are working on the Space Launch System (SLS) rocket and Orion spacecraft for the Artemis campaign, which will return humans to the lunar surface after more than 50 years. Kennedy is the only place on Earth where the SLS rocket is fully assembled prior to launch. Once built, the rocket, spacecraft, and ground systems will undergo rigorous testing and validation in preparation for launching astronauts further and deeper in space than ever before.

“Engineers also are developing technologies that our astronauts will need on the lunar surface. These include 3D printing capability to build structures on the Moon; rovers, and instruments to find water, minerals, and other resources to help sustain a long-term presence; and electrodynamic dust shield technologies that repel the abrasive Moon dust and protect vehicles and sensitive equipment.

“Kennedy’s plant researchers continue working hard to find new ways to grow food in space to supplement the diets of astronauts with key nutrients. And as we advance these technologies, we also administer a number of programs that enable university researchers to help solve other key Moon to Mars challenges.

“While we focus on Moon and Mars, NASA continues to enable the growth of the commercial space sector. Beyond supporting Artemis, our industry and international partners make it possible to launch crews and conduct critical research on the International Space Station. We also rely on commercial expertise to launch many of our robotic science missions that study the Earth, the solar system, and beyond.  

“As we stand at the dawn of a new age of space exploration, I can’t wait to see the innovations and advancements to come. We often hear that “space is hard,” and we at Kennedy take great inspiration from our history, which is full of stories of NASA engineers solving seemingly impossible problems. As we make the next giant leap to the Moon and Mars, Kennedy Space Center is proud to do our part to advance science, inspire the Artemis Generation, and strengthen America’s standing in the world.”

Kunz’s biography is available online, and file images are available from NASA’s image library in vertical and horizontal formats.

Lagniappe for February 2024

Explore the February 2024 edition featuring:

• RS-25 Test on Jan. 27
• Day of Remembrance
• NASA Spinoff

Gator Speaks

There are two reasons why the last Thursday in January and the month of February are important at NASA moving ahead as the Artemis Generation.

Having been around for decades as the NASA Stennis mascot, it is easy to forget important things if you are not intentional about remembering. For newer folks, whether new employees at NASA Stennis or new fans of NASA in general, it is easy not to know something if you are never told about it.

NASA intentionally carves out time each January for a Day of Remembrance to honor members of the NASA family who lost their lives while furthering the cause of exploration and discovery, including the crews of Apollo 1 and space shuttles Challenger and Columbia.

This current moment in space history is a tribute to the men and women who made the ultimate sacrifice. One of the best ways NASA honors the sacrifice made by the previous crew members is by embracing safety as one of the core values at NASA.

This is the cornerstone for mission success as NASA prepares to send the first Artemis astronauts to the Moon. The four astronauts will venture around the Moon on Artemis II as part of NASA’s path to creating a long-term presence on the lunar surface for science and exploration.

The NASA safety culture benefits astronauts, employees, and even surrounding communities where employees participate in daily life. This is a reminder every day at NASA, and especially on the final Thursday in January.

Going forward, the annual Day of Remembrance leads into Black History Month (observed each February), which brings the opportunity to recognize Black Americans who have made contributions to America and NASA’s space program. 

One such person is the late NASA astronaut Ronald McNair, who was honored during the Day of Remembrance. McNair, the second Black astronaut to fly to space, was a member of the Challenger crew. He is one of many African Americans whose contributions helped pave the way for NASA to take giant leaps in space exploration for the Artemis Generation.

May we never forget that it is through the sacrifice and contributions of all that NASA explores for the benefit of all. May we never fail to honor those who have come before us, and may we always remember there is space for everybody – in NASA and all of life.

NASA to Study Effects of Radio Noise on Lunar Science

In February 2024, Intuitive Machines’ IM-1 mission will launch to the Moon’s South Polar region, as part of NASA’s Commercial Lunar Payload Services, or CLPS, initiative. This mission is part of CLPS’ ongoing effort to bring down the cost for science investigations and technology demonstrations going to the Moon and to make them more routine in the lead-up to the Artemis landings later this decade. Among the NASA-provided research flying aboard IM-1 will be an instrument designed to observe the Moon’s surface environment in radio frequencies, to determine how natural and human-generated activity near the surface interacts with and could interfere with science conducted there.

The instrument is called the Radio wave Observation at the Lunar Surface of the photo-Electron Sheath (ROLSES) and is designed to study the dynamic radio energy environment near the lunar surface. It will launch aboard Intuitive Machines’ Nova-C lander.

The ROLSES instrument project is headed up by Dr. Natchimuthuk “Nat” Gopalswamy of NASA’s Goddard Space Flight Center in Greenbelt, Maryland. Gopalswamy describes the design of ROLSES as being a very simple system. “We have four antennas which observe whatever radio emissions are present on the Moon [radio emissions are a type of light, or electromagnetic radiation, which have the longest wavelength, or distance between peaks in their energy waves],” said Gopalswamy. “These antennas are very long, about 8 feet (2.5 meters). But for launching they are packed into a small canister, about 8 inches (21 centimeters) in size.”

The main purpose of ROLSES will be to account for the variety of radiation generated by cosmic phenomena, as well as by human activity on Earth. “There are varying sorts of radio emissions,” said Gopalswamy. “These include activity on Earth that produces radio interference at the lunar surface. And then we have natural radio emissions, coming from Jupiter, coming from the Sun, even coming from our Milky Way galaxy. There is even an emission from Earth that is associated with the Aurora.”

The trick, as Gopalswamy points out, is that each of these types of radio noise produces its own dynamic spectral pattern, somewhat similar to the way in which fingerprints are unique for each person. “The spectrum of each event looks different from the others,” he said. “Therefore, it’s easy for us to identify which is coming from Jupiter, or from the Sun, or from the galaxy, which is very low-frequency background radiation.”

Another source of radio interference will be the lunar lander itself. “Landers obviously have mechanisms, motors and things; they all will produce some kind of radio emission, and that will also be recorded in the spectrum,” said Gopalswamy. “And those will produce distinct features which show that there is interference going on at this particular location.” By identifying this type of interference, scientists can work to sift through the noise it creates when analyzing data returned by instruments like ROLSES. That way, they can hone in on real data, and not “noise” created by non-natural processes.

The four ROLSES antennas are also mounted at two different heights, meaning that once they begin taking measurements, they can provide information on variations in the cloud of negatively charged electrons blasted from the lunar surface by sunlight, and how it changes between different heights. “This way, we can measure the electrons’ density based upon distance from the surface,” said Gopalswamy. “Then we can see how the number of electrons decreases as you go farther from the surface.”

This information, he points out, will be essential when it comes time to design and build future lunar observatories, since the radio frequency interference from the electron cloud and from Earth-based radio transmitters will need to be accounted for.

These radio observations will help build what Gopalswamy calls a library of knowledge on the lunar environment. “That way we will know if we’re at this latitude, at this height, we’re going to have this type of radiation and emission background, and we’ll be able to design our hardware accordingly.” This will aid NASA in its mission to return humans to the Moon over the next decade and beyond, and to establish a sustainable, long-term presence.

ROLSES and IM-1 are part of the agency’s CLPS initiative, which was developed with the goal of creating a lunar economy through commercial deliveries of NASA-provided payloads. With CLPS, private companies of varying sizes and backgrounds are responsible for designing the landers and procuring the launch vehicles, allowing NASA to focus its efforts on designing the instrument payloads. When the agency’s Artemis program establishes a human presence on the Moon, the data gathered by instruments onboard CLPS flights will help astronauts conduct more lunar science.

Station Science 101: Studying DNA in Space

Long-term space exploration exposes humans to radiation that can damage deoxyribonucleic acid or DNA, which carries the genetic information for our development and functioning. Conditions in space also affect the way the body repairs such damage, potentially compounding the risk. Research on the International Space Station studies DNA damage and repair using tools and techniques to sequence, analyze, and even edit DNA.

Those tools and techniques have been developed especially for use in space, which has unique safety considerations and where there are limits on the size and weight of equipment. This specialization has made this type of research possible and resulted in significant milestones in DNA research.

In April 2016, ESA (European Space Agency) astronaut Tim Peake first amplified DNA using the first polymerase chain reaction (PCR) device sent to station, called miniPCR.¹ An important step in the process of analyzing genetic material, amplification involves making multiple copies of a segment of DNA. NASA astronaut Kate Rubin sequenced DNA in space for the first time in August 2016 using a commercial off-the-shelf device called MinION.² In August 2017, NASA astronaut Peggy Whitson combined the miniPCR and MinION to identify the first unknown microbe from the station, validating a process that could make possible in-flight identification of microbes and diagnosis of infectious diseases on future missions.³ In August 2018, NASA astronaut Ricky Arnold first used a “swab to sequencer” DNA sequencing method that eliminates the need to culture bacteria before analysis.⁴

Another milestone, reached in May 2019, was the first CRISPR gene editing on station, performed by NASA astronaut Christina Koch.⁵ CRISPR stands for Clustered Regularly Interspaced Short Palindromic Repeats. These are short, repeated sequences of DNA noted in bacteria with viral DNA sequences in between them. Bacteria transcribe the viral DNA sequences to RNA, which then guides a specific protein to the viral DNA and cuts it – creating a line of defense against invading viruses. Researchers can create a guide RNA to be specific to any part of a genome. This means CRISPR can be used to create precise breaks in a known location of a gene, resulting in simplified gene editing.

A program called Genes in Space has employed these advances for multiple investigations. A collaboration between Boeing and miniPCR bio sponsored by the ISS National Lab and New England Biolabs, this program is a national contest where students in grades 7 through 12 design DNA analysis experiments for the space station.

Genes in Space-6 used CRISPR to successfully generate breaks in the DNA of a common yeast, allow for repair of the breaks, and sequence the patched-up DNA to determine whether its original order was restored, all during spaceflight.⁵ Performing the entire process in space – rather than causing a break, freezing the sample, and sending it into space to repair –provided researchers insight into the type of repair mechanism used. Organisms repair DNA breaks in one of two major ways. One method may add or delete bases while the other rejoins the strands without changing the DNA sequence. Understanding whether one type of repair is less error-prone has important implications for protecting crew members.

Genes in Space-5 represented an important step toward a rapid, safe, and cost-effective way to examine the immune system during spaceflight. This investigation also provided proof of concept for simultaneously amplifying multiple DNA sequences in space, expanding the possibilities for in-flight research and health monitoring.

Genes in Space-10 validated a method for measuring and analyzing the length of DNA fragments known as telomeres using fluorescence. Telomeres, cap-like genetic structures at the end of chromosomes that protect them from damage, shorten with age but have been found to lengthen in space. Analyzing telomere length could help determine the mechanism behind this effect. Results from the investigation also could provide a way to measure DNA and to diagnose genetic-based medical problems during spaceflight. Sending DNA samples back to Earth for analysis can cause the samples to degrade and is not feasible for future long-duration missions. Insight into why telomeres lengthen in space could lead to a better understanding of their role in human aging as well.

Having an entire molecular laboratory in space greatly increases what scientists can do. The ability to analyze DNA, study how it is damaged and repaired in space, and make specific changes to it enables more complex research. Identifying unknown organisms and changes in known ones is key to keeping crew members safe on future missions.

NASA Spinoffs Feature NASA Stennis Developed Technologies

As NASA innovates for the benefit of all, what the agency develops for exploration has the potential to evolve into other technologies with broader use here on Earth. Many of those examples are highlighted in NASA’s annual Spinoff book including dozens of NASA-enabled medical innovations, as well other advancements in 3D printing, robots, and brake designs.

This year’s publication also features a section highlighting technologies developed at agency centers such as NASA’s Stennis Space Center near Bay St. Louis, Mississippi, that are available for use by various industries.

NASA’s 2024 Spinoff highlights more than 40 medical and other commercialized technologies using the agency’s research and development expertise.

“As we continue to push new frontiers and do the unimaginable, NASA’s scientists and engineers are constantly innovating and advancing technologies,” said NASA Administrator Bill Nelson. “A critical part of our mission is to quickly get those advances into the hands of companies and entrepreneurs who can use them to grow their businesses, open new markets, boost the economy, and raise the quality of life for everyone.”

One of the featured medical innovations is the first wireless arthroscope – a small tube carrying a camera inserted into the body during surgery – to receive clearance from the U.S. Food and Drug Administration, which benefited from NASA’s experience with spacesuits and satellite batteries. Commercialized technologies for diagnosing illnesses like the coronavirus, hepatitis, and cancer have also stemmed from NASA’s space exploration and science endeavors. Even certain types of toothpaste originated from the agency’s efforts to grow crystals for electronics.

The book also features several technologies NASA has identified as promising future spinoffs and information on how to license agency tech. Since the 1970s, thousands of NASA technologies have found their way into many scientific and technical disciplines, impacting nearly every American industry.

Additional 2024 Spinoff highlights include developments under NASA’s Artemis campaign, like a small, rugged video camera used to improve aircraft safety and a new method for detecting defects or damage in composite materials. Meanwhile, another spinoff story details the latest benefits of fuel cell technology created more than 50 years ago for Apollo, which is now poised to support terrestrial power grids based on renewable energy.

The book also features other notable spinoffs like:

• Spherical “squishy” robots capable of dropping into dangerous situations before first responders enter
• “Digital winglets” aircraft-routing technology that’s enabling increased fuel efficiency and smoother flights
• Lighter, more durable disc brake designs that produce less dust than traditional disc brakes
• Computer software to help businesses and communities cope with and recover from natural disasters like wildfires
• New 3D printing methods to additively manufacture rocket engines and other large aluminum parts

NASA Stennis items included in the new publication are:

• Remote Sensing Toolkit. The NASA Spinoff 2024 publication describes the remote sensing toolkit as an online portal that offers easy access to NASA Earth-observation data. NASA’s Technology Transfer program at NASA Stennis developed the online resource to promote wider use of the agency’s freely available remote sensing data and software to work with it. It helps users find, analyze, and use the most relevant data for projects such as precision agriculture and crop forecasting, conservation and resource management, and natural disaster planning and response. The free and easy-to-use toolkit includes data from more than 20 satellites and missions.
• Cryogenic Butterfly Cam Valve. According to the NASA Spinoff 2024 book, the unique butterfly valve designed at NASA Stennis provides “no-leak” performance in a broad range of temperatures. The NASA Stennis valve addresses a key disadvantage of current butterfly valves, which require the butterfly disc to establish a tight seal at exactly 90 degrees. Providing additional torque to the valve may cause the disc to rotate beyond 90 degrees, allowing fluid flow. Current butterfly valves also usually fail leakage tests when used with liquid nitrogen, a key cryogenic in propulsion testing. The simple NASA Stennis design remedies these issues by allowing rotation of the valve shaft, enabling the disc to slide until it seals tightly despite temperature changes. The NASA Stennis valve can be used in various aerospace, natural gas, and cryogenic plant systems.

“As NASA’s longest continuously running program, we continue to increase the number of technologies we license year-over-year while streamlining the development path from the government to the commercial sector,” said Daniel Lockney, Technology Transfer program executive at NASA Headquarters in Washington. “These commercialization success stories continually prove the benefits of transitioning agency technologies into private hands, where the real impacts are made.”

Spinoffs are part of NASA’s Space Technology Mission Directorate and its Technology Transfer program. Tech Transfer is charged with finding broad, innovative applications for NASA-developed technology through partnerships and licensing agreements, ensuring agency investments benefit the nation and the world.
