Safely Delivering our 

Mission, Virtually 

and On-Site

The successful Saffire IV experiment exemplifies our ability to 

deliver on our missions while operating virtually. Recently, a limited 

number of mission-critical projects 

have returned to on-site work. 

With the recent upsurge in local 

COVID–19 cases, we continue to 

be mindful of maintaining health 

and safety. Due to your diligence 

in practicing social distancing, 

wearing face coverings, and hand 

washing, we are able to continue to 

deliver on our commitments while 

keeping everyone safe and healthy.

Thank you for your continued 

focus on your health and safety!

NASA Glenn and University Hospitals (UH) have collaborated on new methods 

and technologies for decontaminating personal protective equipment (PPE) for 

workers caring for patients with coronavirus (COVID–19).

A team of researchers recently developed and tested two new approaches 

that could enable health care professionals to sanitize masks on-site and 

safely reuse them. These approaches also may be useful to the aerospace 

community when traditional sterilization techniques might not be available.

Atomic Oxygen Method

Glenn Environmental Effects and Coatings Branch members—Sharon Miller, 

research engineer, and Bruce Banks, physicist—developed a process and 

hardware to decontaminate masks using atomic oxygen. Prevalent in lowEarth orbit, these single oxygen atoms can remove organic materials that 

cannot easily be cleaned by other methods.

that decontaminates masks using atomic oxygen.

“On Earth, we create atomic oxygen by putting ozone (O3) 

in a chamber and heating it,” Miller said. “As the ozone 

decomposes into atomic oxygen, it can kill organisms like 

viruses.”

Further testing is needed to verify the method can be 

used to perform multiple decontamination cycles without 

damaging the PPE. Recent filtration tests performed at 

an independent testing laboratory showed N95 masks 

filter well and pass acceptance testing after 20 minutes 

of atomic oxygen treatment. In early May, NASA provided 

a prototype for UH to test on N95 masks. Early results 

confirm the method deactivates the virus, and continued 

testing will determine the minimum ozone concentration 

and exposure time needed for disinfection.

“Ozone diffuses easily through and around objects, which 

makes it promising for sterilizing inside an N95 mask filter 

or loosely stacked masks, and it could potentially sterilize 

without leaving a residue,” Banks said. “The process 

could be scaled up to treat multiple batches of PPE or 

made portable for small hospitals in rural areas. No liquid 

chemicals would be needed, just oxygen and nitrogen gas.”

Peracetic Acid Method

UH doctors Amrita John and Shine Raju, infectious disease 

and critical care physicians, are examining peracetic acid 

as an option for decontaminating PPE. Peracetic acid is a 

chemical disinfectant commonly used in the health care, 

food and water treatment industries.

“We found that the peracetic acid disinfection method is very 

effective in killing 99.9999% of viruses and even highly 

resistant bacterial spores from contaminated N95 masks 

without any detectable loss of filtration, structural integrity 

and strap elasticity for up to five decontamination cycles,” 

Raju said. “We believe that the peracetic acid disinfection 

method is the fastest method of mass-decontamination of 

N95 respirators currently available.” 

The U.S. Department of Veterans Affairs (VA), Case Western 

Reserve University and Glenn are participants in this multiinstitutional study.

“We have been honored to join forces with the NASA team, 

as well as researchers at the VA and Case, to promote 

innovation discovery in this new frontier,” said Kipum Lee, 

managing director of the UH Ventures Innovation Center and 

co-lead of the alternative PPE strategy team.

Are you feeling uncomfortable in your home office? You can increase your comfort by applying 

ergonomic principles! They will help you wherever you are working—in your NASA office, home 

office, garage, kitchen, or garden! The two major issues observed during assessments are lack of 

movement and incorrect posture. Here are some important factors from Glenn’s Occupational Health 

Branch to keep in mind while working from home. 

Movement

After 20 minutes of inactivity, the body and brain begin to fatigue and the discs in the 

spinal vertebrae begin to settle.

• Take a microbreak—20-second to 2-minute walk and/or stretch/exercise session—

every 20 minutes.

• Move as much as possible throughout the day.

• Stand up (using a countertop or homemade stand up desk). No more than 20

minutes at a time; stand 2 - 4 hours per day.

Chair comfort 

• Use a folded blanket to increase height and to add seat padding. Use a

rolled-up towel behind the lower back for lumbar support. 

• Use a footrest while sitting and standing; make one out of a sturdy box

or a rolled-up blanket.

• Alternate each foot on the footrest every 10 minutes.

Monitors 

• Position them approximately an arm’s length from face.

• Do not lean—if you have trouble seeing the information on your screen,

move your monitor closer or increase the size of the text on your screen.

• The top of the monitor should be below eye-level.

• Follow the 20/20/20 rule—every 20 minutes, look 20 feet away from

the monitor for 20 seconds.

Posture

Maintain good posture throughout the day.

Workstation

• Body should be relaxed and remain in a straight and forward-facing position.

• Ears should be directly above the shoulders and nose should be aligned with

the bellybutton.

• Upper arms should be close to your body and elbows should be next to your waist.

• Forearms should be parallel to the floor and aligned with wrists/hands while typing.

• Work surface should be just below elbow height.

• Avoid awkward or static positions, reaching or twisting.

• Do not rest arms/wrists/hands on any surface.

Students Find Benefits 

Through Virtual Internships

NASA Glenn is holding its first-ever virtual internship session this summer with over 100 interns joining 

the center remotely to provide socially distanced support. While teleworking is an adjustment from 

traditional on-site experiences, many interns are discovering advantages to interning remotely. Here are a 

few comments from 2020 summer students interning through Glenn’s Office of STEM Engagement. 

Carnell W. Bolden, University 

 of Miami

Air-Breathing Propulsion Branch

Mentor: Dr. Arman Mirhashemi

Interning remotely at Glenn this summer 

has not stopped Bolden from making 

meaningful connections with other 

engineers and employees at NASA. 

Bolden’s work involves an ultrasound 

tomography temperature technique to 

measure temperature fields.

“Working remotely also has the unique 

advantage of teaching myself and others 

to be adaptable,” said Bolden, “so that 

when the adversities of life may come, we 

can respond and progress to be stronger, 

smarter and more resilient than ever.”

Jason E. Fantl, University 

 of Wyoming

Secure Networks, Systems

 Integration and Test Branch

Mentor: Rachel Dudukovich

Fantl is working on the architecture of 

high-speed delay-tolerant networking. 

While he wishes he could have seen 

Glenn’s facilities in person this summer, 

he’s thankful that his work translates well 

into teleworking.

“The bulk of what I’m doing is 

programming,” said Fantl, “and luckily 

computer science is set up nicely to be 

done remotely.”

 Systems Branch

Mentor: Jeremiah McNatt

As a way of staying connected, interns 

have been placed into groups led by peer 

leaders who organize weekly meetings for 

everyone to “check in and talk.” Nicole 

Swatton, a returning NASA intern, is one 

of the peer leaders, and so far, she’s found 

her experience to be a rewarding one.

“The interns are really receptive and 

understanding to the peer groups,” said 

Swatton. “It’s nice that they are willing to 

talk and put in the effort to meet up.”

Letizia Moro, Boise State University

System Architectures and Analytical Studies Branch

Mentor: Michael A. Marsden

Moro is working with image processing and artificial intelligence. Her 

project deals specifically with using technology on airplanes at airports to 

accomplish tasks such as recognizing and matching tail numbers to flight 

information and camera tracking.

“I’m so thankful that NASA offers this internship program! A lot of my friends 

had their internships cancelled,” said Moro.

Josh K. Smith, University of Arizona

Intelligent Control and Autonomy Branch

Mentor: Dr. Jonathan Litt

Smith is helping model power propulsion systems for autonomous vehicles. 

When he is not working on this project, he is attending virtual events 

organized by the Office of STEM Engagement for interns, which include 

presentations from employees and guided virtual tours. 

“Through this virtual internship, I’ve been able to network with many other 

centers and many other people,” said Smith, a first-time intern from 

Phoenix, Arizona. “I’m talking to people across the country right now.”

Conner E. Stevons, University of Michigan 

Space Communications & Spectrum Management Office

Mentors: Ian Nemitz, Evan Katz and Brian Vyhnalek

Along with the work he is doing in quantum communications, Stevons said 

his assigned group of interns has been helpful in making new connections 

at Glenn this summer, albeit virtually.

“The unexpected friendships I’ve built so far are great. I thought it’d be 

much more difficult,” said Stevons. “Hopefully we’ll meet up in the future 

when the pandemic is over or contained a little bit better.”

Mónica A. Santiago, Polytechnic 

 University of Puerto Rico

Aviation Test Branch

Mentor: Dr. Waldo J. Acosta

For Santiago, who is teleworking from her home in Puerto Rico, NASA’s 

decision to hold internships virtually this summer provides more accessibility 

for interns living far away. She is working with the Icing Research Tunnel 

and relocating heating systems to minimize heat losses and reduce the time 

required for them to heat up again.

“Remotely interning gives students the opportunity to work from home and still 

be a part of the whole process,” said Santiago. “There are no barriers.”

Student-Built Lockers Fly

on NASA’s Historic Mission 

“Over 1,300 items designed and built by students have flown to 

the space station and NASA Johnson tracks all the individual 

products that go up, just like these four lockers,” Hall said. 

“We also allow the students, teachers and mentors to sign 

the lockers. I know one of the lockers that my students and I 

signed, made it to the space station.”

In addition to mentoring students from 13 design and 

prototype schools, Hall also worked with five HUNCH culinary 

schools/academies, three hardware schools, and two soft 

goods schools for the 2019-2020 school year. 

For more information on mentoring or referring your schools to 

the NASA HUNCH program, visit https://nasahunch.com

By S. Jenise Veris

People around the world celebrated the safe arrival of NASA’s 

SpaceX Demo-2 crew and cargo to the International Space 

Station, May 31.

For Glenn scientist Nancy Hall, seeing four HUNCH storage 

lockers among the cargo on the historic flight represented 

a victory. It meant that students, possibly some that Hall 

mentors, in the High School Students United with NASA to 

Create Hardware (HUNCH) Program designed and built parts 

that went into these four lockers.

HUNCH is an innovative school-based program that partners 

NASA centers with over 277 high schools across the nation 

to develop items that will ease living conditions aboard the 

space station. The projects vary from hardware to personal 

soft goods and culinary requests from the astronauts or NASA 

Flight Crew Systems and Operational groups. 

These HUNCH single stowage lockers (SSLs) carried liquid 

cooling ventilation garments, crew shoes and an exercise 

harness for the astronauts. One of the HUNCH lockers with signatures on the space station.
