We will miss him and are excited to see what his next journey entails.”
As he transitions from government service, Cassada will return to the private sector, working on extremely low light detection technologies with broad and emerging applications in various areas, including quantum networks and computing, remote sensing, long-range communication, semiconductor manufacturing, and medical imaging.
“I am incredibly grateful for my many opportunities here at NASA,” Cassada said, “and especially to have served alongside some of the most amazing people both on and off our planet, accomplishing things that are only possible when we work and innovate together as a team. As humans, we explore . And each scientific adventure, whether in a lab on Earth or in space, requires courage to explore and advance society. I am incredibly fortunate to have been surrounded by explorers during my entire career so far and going forward. An expedition may seem daunting, but it’s a lot less so when you’re prepared and with the right crewmates.”
Before his selection by NASA in 2013 as a member of NASA’s 21st Class, Cassada earned his doctorate in High Energy Particle Physics from the University of Rochester, New York and was a U.S. Navy pilot, instructor pilot, test pilot, and instructor test pilot. Throughout his career, Cassada has accumulated more than 4,000 flight hours in over 50 different aircraft and has been awarded various military and civilian awards.
Cassada graduated from White Bear Lake Area High School in Minnesota in 1991 and received his bachelor’s in Physics in 1995 from Albion College in Michigan.

Interstellar Lab, a small business comprised of team members from France, Texas, and Florida, took home the $750,000 grand prize for their food system, NUCLEUS, which uses a multi-pronged approach to growing and harvesting food outputs for astronauts on long-duration human space exploration missions.Credit: OSU/CFAES/Kenneth Chamberlain NASA has awarded a total of $1.25 million to three U.S. teams in the third and final round of the agency’s Deep Space Food Challenge. The teams delivered novel food production technologies that could provide long-duration human space exploration missions with safe, nutritious, and tasty food.
The competitors’ technologies address NASA’s need for sustainable food systems for long-duration habitation in space, including future Artemis missions and eventual journeys to Mars. Advanced food systems also could benefit life on Earth and inspire food production in parts of the world that are prone to natural disasters, food insecurity, and extreme environments.
“The Deep Space Food Challenge could serve as the framework for providing astronauts with healthy and delicious food using sustainable mechanisms,” said Angela Herblet, challenge manager for the Deep Space Food Challenge at NASA’s Marshall Space Flight Center in Huntsville, Alabama. “The challenge has brought together innovative and driven individuals from around the world who are passionate about creating new solutions that support our agency’s future Moon to Mars missions.”
Since the challenge’s launch in 2021, more than 300 teams from 32 countries have participated by submitting innovative food system designs. The competition, conceived and managed by NASA Centennial Challenges at NASA Marshall, is a first-of-its-kind coordinated effort between NASA and CSA (Canadian Space Agency), which ran its own challenge in parallel.
Four American teams competed in Phase 3, which began in September 2023. The Methuselah Foundation partnered with Ohio State University to facilitate the final phase of the challenge, which included a two-month testing and demonstration period held on the university’s campus in Columbus, Ohio. Each U.S. team in Phase 3 was awarded $50,000 and took their technology to Columbus for testing.
Throughout this phase, the teams constructed full-scale food production systems that were required to pass developmental milestones like safety, sensory testing, palatability, and harvesting volumes. Each team worked with four “Simunauts,” a crew of Ohio State students who managed the testing and demonstrations for Phase 3 over the eight-week period. The data gathered from testing was delivered to a judging panel to determine the winner.
The challenge concluded at the Deep Space Food Symposium, a two-day networking and learning summit at the Nationwide and Ohio Farm Bureau 4-H Center on Aug. 15 and 16. Throughout the event, attendees met the Phase 3 finalists, witnessed demonstrations of the food production technologies, and attended panels featuring experts from NASA, government, industry, and academia. The winners of the challenge were announced at an awards ceremony at the end of the symposium.
The U.S. winner and recipient of the $750,000 grand prize is Interstellar Lab of Merritt Island, Florida. Led by Barbara Belvisi, the small business combines several autonomous phytotrons and environment-controlled greenhouses to support a growth system involving a self-sustaining food production mechanism that generates fresh vegetables, microgreens, and insects necessary for micronutrients.
Two runners-up each earned $250,000 for their food systems’ successes: Nolux of Riverside, California, and SATED of Boulder, Colorado.
Nolux, a university team led by Robert Jinkerson, constructed an artificial photosynthetic system that can create plant and fungal-based foods without the operation of biological photosynthesis.
Standing for Safe Appliance, Tidy, Efficient & Delicious, SATED is a one-man team of Jim Sears, who developed a variety of customizable food, from pizza to peach cobbler. The product is fire-safe and was developed by long-shelf-life and in-situ grown ingredients.
NASA also selected and recognized one international team as a Phase 3 winner: Solar Foods of Lappeenranta, Finland, developed a food production system through gas fermentation that relies on single-cell protein production.
In April 2024, CSA and Impact Canada awarded the grand prize winner of its parallel challenge to Ecoation, a Vancouver-based small business specializing in greenhouses.
“Congratulations to the winners and all the finalist teams for their many years dedicated to innovating solutions for the Deep Space Food Challenge,” said Amy Kaminski, program executive for NASA’s Prizes, Challenges, and Crowdsourcing at NASA Headquarters in Washington. “These food production technologies could change the future of food accessibility on other worlds and our home planet.”
Also present at the symposium was celebrity chef and cookbook author Tyler Florence. After spending time with each finalist team and getting acquainted with their food systems, Florence selected one team to receive the “Tyler Florence Award for Culinary Innovation.” Team SATED of Boulder, Colorado, received the honor for their system that impressed Florence due to its innovative approach to the challenge.
The Deep Space Food Challenge, a NASA Centennial Challenge, is a coordinated effort between NASA and CSA. Subject matter experts at Johnson Space Center in Houston and Kennedy Space Center in Florida, supported the competition. NASA’s Centennial Challenges are part of the Prizes, Challenges, and Crowdsourcing program within NASA’s Space Technology Mission Directorate and managed at Marshall Space Flight Center in Huntsville, Alabama. The Methuselah Foundation, in partnership with NASA, oversees the United States and international competitors.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA’s C-20A aircraft completed more than 150 hours of international science flights from May 20 to July 24 in support of an Earth science deployment series. The aircraft, owned and operated by NASA’s Armstrong Flight Research Center in Edwards, California, overcame several challenges throughout the missions.NASA/Carla Thomas Operating internationally over several countries this summer, NASA’S C-20A aircraft completed more than 150 hours of science flights across two months in support of Earth science research and overcame several challenges throughout its missions.
Based at NASA’s Armstrong Flight Research in Edwards, California, the C-20A research aircraft has been modified to support the Uninhabited Aerial Vehicle Synthetic Aperture Radar and SAR-fusion camera. The instruments, built and operated by NASA’s Jet Propulsion Laboratory in Southern California, collect data and images of Earth’s surface for use in understanding global ecosystems, natural hazards, and land surface changes.
From May 20 to July 24, the team crossed the Atlantic and deployed to several locations in Africa, as well as Germany, for two campaigns. They included the Africa Synthetic Aperture Radar (AfriSAR) mission, in collaboration with the European Space Agency, and the Germany Bistatic Experiment, in collaboration with the German Aerospace Center.
For the AfriSAR mission, researchers collected airborne data over African forests, savannas, and wetlands for use in studies of Earth’s ecosystems. Datasets collected over Germany will be used to develop land surface height maps.
NASA team members pose in front of the C-20A aircraft while in Sao Tome, Africa, May 24, 2024. From left, Kirt Stallings, Joe Piotrowski Jr., Adam Vaccaro, Carrie Worth, Tim Miller, Otis Allen, Roger “Todd” Renfro, Edgar Aragon-Torres, Ryan Applegate, and Isac Mata.NASA The flight team successfully achieved its missions despite several challenges, including mechanical and technical issues with the aircraft. Despite the challenges, the team resolved issues quickly and worked to minimize impacts to the science schedule and objectives.
“We prepared for the unexpected and we expected to be unprepared,” said Shawn Kern, NASA Armstrong’s director of safety and mission assurance and a C-20A pilot. “With that mindset, we were ready to adapt and change the plans as needed, and met challenges with a lot of resilience, a lot of innovation, and a lot of improvised solutions to get things done despite some significant roadblocks.”
The team included aircraft mechanics, avionics technicians, quality assurance representatives, science leads and instrument operators, operation engineers, mission managers, and pilots. They were also supported by project management, safety, logistics, weather, and maintenance personnel at NASA Armstrong.
NASA pilots Kirt “Skirt” Stallings and Carrie Worth fly the C-20A aircraft over Africa on July 9, 2024.NASA “It was really the teamwork, improvisation, and creativity that resolved these unexpected challenges that made the mission a success.” Kern added.
Gathering scientific data in unique regions and conditions is necessary to understanding climate on the global scale. Data generated from these two airborne campaigns can be used to support the calibration and validation of data from future satellite-based missions like NISAR (NASA ISRO Synthetic Aperture Radar).
“Airborne campaigns like these are essential for enabling space-based technology. There are often measurements and science that simply cannot be achieved from satellites alone, and so they require airborne data collection.” said Gerald Bawden, program scientist for studies of Earth’s surface and interior at NASA Headquarters in Washington. “This deployment advanced both of these areas and was enabled by this team.”

Behind Diane is the SOFIA aircraft and her arm rests on a railing beside her. Credit: Diane Ripollone A 35-year-veteran educator, Diane Ripollone teaches Earth science, astronomy, and physics to high school students in North Carolina. In her decades of experience, she’s seen firsthand how students with physical challenges can face difficulties in connecting with lessons. She decided to tackle the issue head-on with her internship.
Ripollone supports the My NASA Data Program, which provides educational materials to interact with live data collected by NASA satellites, observatories, and sensors worldwide. As a NASA intern, she has worked to create physical materials with braille for students with- vision limitations.
“It’s a start for teachers,” Ripollone said. “Although every classroom is different, this helps to provide teachers a jumpstart to make engaging lesson plans centered around real NASA data.” Her NASA internship has excited and inspired her students, according to Ripollone. “My students have been amazed! I see their eyes open wide,” she said. “They say, ‘My teacher is working for NASA!'”
Felicia Haseleu: Improving Reading and Writing Skills
North Dakota teacher Felicia Haseleu never imagined she’d be a NASA intern until a colleague forwarded the opportunity to her inbox. A teacher on her 11th year, she has seen how COVID-19 has affected students: “It’s caused a regression in reading and writing ability,” a shared impact that was seen in students nationwide.
A science teacher passionate about reading and writing, Felicia set out to utilize these in the science curriculum. As an intern with My NASA Data, she’s prepared lesson plans that combine using the scientific method with creative writing, allowing students to strengthen their reading and writing skills while immersing themselves in science.
Haseleu anticipates her NASA internship will provide benefits inside and outside the classroom.
“It’s going to be awesome to return to the classroom with all of these materials,” she said. “Being a NASA intern has been a great experience! I’ve felt really supported and you can tell that NASA is all encompassing and supports one another. From the camaraderie to NASA investing in interns, it’s nice to feel valued by NASA.”
Teri Minami: Hands-on Lesson for Neurodivergent and Artistic Students

Credit: Teri Minami “I’ve never been a data-whiz; I’ve always connected with science hands-on or through art,” said NASA intern Teri Minami, a teacher of 10 years in coastal Virginia. She cites her personal experience in science to guide her to develop lessons using NASA data for neurodivergent students or those with a more artistic background.
Through her NASA internship, she aims to create lesson plans which allow students to engage first-hand with science while outdoors, such as looking at water quality data, sea level ice, and CO2 emissions, taking their own measurements, and doing their own research on top of that.
Although many people associate being an intern with being an undergraduate in college, NASA interns come from all ages and backgrounds. In 2024, the agency’s interns ranged in age from 16 to 61 and included high school students, undergraduates, graduate students, doctoral students, and teachers.
