Preparations for Next Moonwalk Simulations Underway (and Underwater)
While astronaut Gene Cernan was on the lunar surface during the Apollo 17 mission, his spacesuit collected loads of lunar dust. The gray, powdery substance stuck to the fabric and entered the capsule causing eye, nose, and throat irritation dubbed “lunar hay fever.” Credit: NASACredit: NASA Moon dust, or regolith, isn’t like the particles on Earth that collect on bookshelves or tabletops – it’s abrasive and it clings to everything. Throughout NASA’s Apollo missions to the Moon, regolith posed a challenge to astronauts and valuable space hardware.
During the Apollo 17 mission, astronaut Harrison Schmitt described his reaction to breathing in the dust as “lunar hay fever,” experiencing sneezing, watery eyes, and a sore throat. The symptoms went away, but concern for human health is a driving force behind NASA’s extensive research into all forms of lunar soil.
The need to manage the dust to protect astronaut health and critical technology is already beneficial on Earth in the fight against air pollution.
Working as a contributor on a habitat for NASA’s Next Space Technologies for Exploration Partnerships (NextSTEP) program, Lunar Outpost Inc. developed an air-quality sensor system to detect and measure the amount of lunar soil in the air that also detects pollutants on Earth.
Originally based in Denver, the Golden, Colorado-based company developed an air-quality sensor called the Space Canary and offered the sensor to Lockheed Martin Space for its NextSTEP lunar orbit habitat prototype. After the device was integrated into the habitat’s environmental control system, it provided distinct advantages over traditional equipment.
Rebranded as Canary-S (Solar), the sensor is now meeting a need for low-cost, wireless air-quality and meteorological monitoring on Earth. The self-contained unit, powered by solar energy and a battery, transmits data using cellular technology. It can measure a variety of pollutants, including particulate matter, carbon monoxide, methane, sulfur dioxide, and volatile organic compounds, among others. The device sends a message up to a secure cloud every minute, where it’s routed to either Lunar Outpost’s web-based dashboard or a customer’s database for viewing and analysis.
The oil and gas industry uses the Canary-S sensors to provide continuous, real-time monitoring of fugitive gas emissions, and the U.S. Forest Service uses them to monitor forest-fire emissions.
“Firefighters have been exhibiting symptoms of carbon monoxide poisoning for decades. They thought it was just part of the job,” explained Julian Cyrus, chief operating officer of Lunar Outpost. “But the sensors revealed where and when carbon monoxide levels were sky high, making it possible to issue warnings for firefighters to take precautions.”
The Canary-S sensors exemplify the life-saving technologies that can come from the collaboration of NASA and industry innovations.

The Moon is pictured on Dec. 7, 2022, the day before its Full Moon phase from the International Space Station as it orbited above the southern Indian Ocean.Credit: NASA NASA will coordinate with U.S. government stakeholders, partners, and international standards organizations to establish a Coordinated Lunar Time (LTC) following a policy directive from the White House in April. The agency’s Space Communication and Navigation (SCaN) program is leading efforts on creating a coordinated time, which will enable a future lunar ecosystem that could be scalable to other locations in our solar system.
The lunar time will be determined by a weighted average of atomic clocks at the Moon, similar to how scientists calculate Earth’s globally recognized Coordinated Universal Time (UTC). Exactly where at the Moon is still to be determined, since current analysis indicates that atomic clocks placed at the Moon’s surface will appear to ‘tick’ faster by microseconds per day. A microsecond is one millionth of a second. NASA and its partners are currently researching which mathematical models will be best for establishing a lunar time.
To put these numbers into perspective, a hummingbird’s wings flap about 50 times per second. Each flap is about .02 seconds, or 20,000 microseconds. So, while 56 microseconds may seem miniscule, when discussing distances in space, tiny bits of time add up.
“For something traveling at the speed of light, 56 microseconds is enough time to travel the distance of approximately 168 football fields,” said Cheryl Gramling, lead on lunar position, navigation, timing, and standards at NASA Headquarters in Washington. “If someone is orbiting the Moon, an observer on Earth who isn’t compensating for the effects of relativity over a day would think that the orbiting astronaut is approximately 168 football fields away from where the astronaut really is.”
As the agency’s Artemis campaign prepares to establish a sustained presence on and around the Moon, NASA’s SCaN team will establish a time standard at the Moon to ensure the critical time difference does not affect the safety of future explorers. The approach to time systems will also be scalable for Mars and other celestial bodies throughout our solar system, enabling long-duration exploration.
As the commercial space industry grows and more nations are active at the Moon, there is a greater need for time standardization. A shared definition of time is an important part of safe, resilient, and sustainable operations,” said Dr. Ben Ashman, navigation lead for lunar relay development, part of NASA’s SCaN program.
NASA’s SCaN program serves as the office for the agency’s space communications operations and navigation. More than 100 NASA and non-NASA missions rely on SCaN’s two networks, the Near Space Network and the Deep Space Network, to support astronauts aboard the International Space Station and future Artemis missions, monitor Earth’s weather and the effects of climate change, support lunar exploration, and uncover the solar system and beyond.

Almost a decade ago, then-grad student Kyle Helson contributed to early paperwork for NASA’s EXCITE mission. As a scientist at Goddard, Helson helped make this balloon-based telescope a reality: EXCITE launched successfully on Aug. 31.
Name: Kyle Helson
Title: Assistant Research Scientist
Organization: Observational Cosmology Lab (Code 665), via UMBC and the GESTAR II cooperative agreement with NASA Goddard
Dr. Kyle Helson is an assistant research scientist at NASA’s Goddard Space Flight Center in Greenbelt, Md. Photo credit: Dr. Amy Bender How did you know you wanted to work at NASA Goddard?
When I was finishing my physics Ph.D. at Brown University in 2016, I was talking to Ed Wollack and Dave Chuss at Goddard about the NASA postdoc program, and they suggested I apply. Luckily, I got the postdoc fellowship to come here to Goddard to work on cosmic microwave background detector testing and other related research.
I don’t think I would have realized or been interested in coming here had I not had that NASA Space Technology Research Fellowship when I was in grad school and gotten the opportunity to spend some time here and work with Ed and Dave.
What is the name of your team that you’re working with right now?
One of the projects I work on is the Exoplanet Climate Infrared TELescope (EXCITE). EXCITE is a scientific balloon-borne telescope that is designed to measure the spectra of hot, Jupiter-like exoplanet atmospheres in near-infrared light.
Related: NASA’s EXCITE Mission Prepared for Scientific Balloon Flight What is your role for that?
I do a little bit of everything. During grad school, I worked on the first few iterations of the proposal for EXCITE back in 2015 and 2016.
Over the past few years here at Goddard, I’ve been responsible for parts of a lot of the different subsystems like the cryogenic receiver, the gondola, the electronics, and integration and testing of the whole payload.
Last year, we went to Fort Sumner, New Mexico, for an engineering flight. Unfortunately, we were not able to fly for weather reasons. We went back last month, and I was again part of the field deployment team. We take the whole instrument, break it down, carefully ship it all out to New Mexico, put it back together, test it, and get it ready for a flight.

What I like about working on a project like EXCITE is that we get to kind of do a little bit of everything.
We’ve been able to see the experiment from concept and design to actually getting built, tested and hopefully flown and then subsequent data analysis after the flight. What I think is really fun is being able be with an experiment for the entire life cycle.
How do you help support Goddard’s mission?
We’re studying exoplanets, which definitely fits within the scientific mission of Goddard. We’re also a collaboration between Goddard other academic institutions, like Arizona State, like Brown University, Cornell, and several other places, and so we’re also members of the larger scientific research community beyond NASA.
We also have a number of graduate students working on EXCITE. Ballooning is a good platform for training students and young researchers to learn how to build and design instruments, do data analysis, etc. One of the missions of NASA and Goddard is to train early career scientists like graduate students and post docs, and balloons provide a good platform for that as well.
Balloon missions like EXCITE also provide a good platform for technology advancement and demonstration in preparation for future satellite missions.
How did you know cosmology was what you wanted to pursue?
When I was a kid, I loved space. I wanted to be an astronaut when I was a kid. I even went to space camp.
The first time I ever got to see physics was a middle-school science class. That was the first time we ever learned physics or astronomy that was deeper than just identifying planets or constellations. We started to learn how we could use math to measure or predict experiments.
When I was in college, I remember talking to my undergraduate academic adviser, Glenn Starkman, and talking about what research I might like to do over the summer between sophomore and junior year of college. I wasn’t really sure what I wanted to do or what I was interested in, and he suggested I talk to some of the professors doing astrophysics and cosmology research and see if they had space for me in their lab.
I ended up finding a great opportunity working in a research lab in college — so it was working in the physics department in Case Western.
That’s where I first started learning about computer-aided design (CAD), and designing things in CAD, and that’s where I first learned how things get made in a machine shop, like on a mill, or a lathe. These skills have come in handy ever since, because I do a lot of design work in the lab. And I was lucky growing up that my dad was really hands-on and liked to fix things and build things and he taught me a lot of those skills as well.

My dad had a big influence. I think all the different people I’ve had the opportunity to learn from and work with who have been mentors along the way. My research advisers, professor John Ruhl in college, professor Greg Tucker in grad school, and Dr. Ed Wollack as a postdoc have all been very influential. Additionally, I have had the opportunity to work with a lot of very good post docs and research scientists during my career, Dr. Asad Aboobaker, Dr. Britt Reichborn-Kjennerud, Dr. Michele Limon, among others.
Throughout a career, there are tons of other people on the way from whom you pick up little things here and there that stick with you. You look back and you realize five years later you still do this one thing a certain way because someone helped you and taught you this skill or technique.
Where is a place you’d like to travel to?
Since I was lucky enough to go to Antarctica in graduate school, I figured that is the hardest continent to travel to, so now I have a mission to go to every continent. I’ve been to North America, I’ve been to South America, I’ve been to Asia, Europe, and Australia and New Zealand, but I’ve never been to Africa.

I’m a competitive track cyclist. I started racing bikes in collegiate racing as a grad student at Brown. Many summers I’ve spent many weekends driving and flying all over the U.S. to race in the biggest track cycling events in the country.
What would be your three-word-memoir?
Curious, compassionate, cat-dad.
