The Florida Space Institute is on the verge of launching a Blue Origin payload into space.

If all goes as planned, Julie Brisset’s NASA-funded project will send an experiment into space. Brisset, interim director of the Florida Space Institute, has a passion for advancing space exploration, which the project aims to do.

The technology to be tested is a Dust In-situ Manipulation System (DIMS) — a payload designed to create and control dust clouds in low-gravity environments, specifically for simulating how dust behaves in undisturbed environments, for example interstellar dust clouds or pollution aerosols in our atmosphere.

It’s designed for use in microgravity conditions, such as those found in space, to study dust particle behavior, including their levitation, size sorting, interaction with light and its implications for understanding planetary environments.

“Once you start research in this field, it is surprising to see how important dust is in many applications,” Brisset says. “From the confines of our universe to the lunar surface and our own atmosphere, dust particles play a key role in many physical processes.”

By studying dust clouds in a controlled setting, DIMS can provide insights into protoplanetary disks and other celestial bodies.

Using a combination of low gas pressure and thermal piezoelectric elements, it allows for the creation of a cloud of dust grains and its motion across the volume of the experiment at various speeds. Piezoelectric elements convert mechanical energy, such as pressure or vibration, into electrical energy, and vice versa.

DIMS will create a 3D image of a dust cloud using high-speed cameras from two different angles. It is designed to overcome current limitations related to the levitation of dust clouds in microgravity including size sorting, preferential particle orientation, hardware constraints and residual accelerations.

This technology was developed to offer a general platform supporting experiments over a range of applications, including astrophysics (spectroscopy of interstellar dust), planetary sciences (interplanetary dust, planetary rings, early stages of planet formation) and atmospheric sciences (aerosols).

“The ultimate goal is an orbital platform that can be useful for a range of scientific activities,” Brisset says.

In addition, as it allows for the motion of dust at various speeds, the DIMS technology will demonstrate a possible dust transport mechanism in future ISRU applications, such as asteroid mining or Lunar water extraction from regolith. The DIMS project was supported by the NASA Flight Opportunities Program and allowed for the training of many students and early career scientists over the years.

“Such programs are a great intersection between science, technology development, and education,” Brisset says.

This experiment is funded by NASA and conducted in collaboration with Technischen Universität Braunschweig.

Robot Rovers on the “Moon”: Lunabotics Challenge Preps Students for Space Careers /news/robot-rovers-on-the-moon-lunabotics-challenge-preps-students-for-space-careers/ Thu, 09 May 2024 15:10:59 +0000 /news/?p=141440 College teams, including a group of Knights, will build robot rovers and compete at the new Regolith Bin at 鶹ӳý’s Exolith Lab before the best crews advance to finals at Kennedy Space Center.

]]>
More than 40 college teams from across the U.S. designing and building autonomous vehicles will soon find out if they are capable of navigating and conducting missions on a simulated lunar surface resembling the moon.

The robot rovers won’t be going into space — but they will face the next best challenge: to build a berm structure which would be useful to NASA’s Artemis program for navigating during lunar landings and launches, shading cryogenic propellant tank farms, providing radiation protection around a nuclear power plant and other mission-critical uses.

NASA created the Lunabotics Challenge in support of the Artemis program. ’s Florida Space Institute and its Exolith Lab will host the first round, sponsored by Caterpillar Inc., on May 11-14. The top 10 teams will advance to the demonstrations phase of the competition at the Kennedy Space Center May 15-17.

At 鶹ӳý, students will be testing and showcasing their rovers in the same regolith bin that NASA, the European Space Agency and many companies use to evaluate and improve new equipment and technologies before launching them into space. Leaders in key industries that are important to Florida’s and the region’s workforce will serve as judges.

“Lunabotics gives students from throughout the United States an unrivaled opportunity to apply their knowledge of robotics and space to NASA’s design and construction processes,” says Winston Schoenfeld, 鶹ӳý interim vice president for research. “The future of our space and many other high-tech industries depends on preparing a talented workforce that can innovate and work in highly collaborative team environments.”

Each team of college students has spent months designing and building a robot rover to NASA specifications that, during this challenge, will autonomously navigate a lunar-simulated arena and excavate regolith. They will compete two teams at a time per round, being given a set amount of time to collect regolith from the construction zone and dump it into a berm zone. Teams will be judged on a variety of factors, chiefly, the size of the berm they are able to build up in the regolith material with the rover.

The top 10 teams then travel to Kennedy Space Center for the culminating event, to demonstrate the operation of their functional tele-operated or autonomous robot to complete the lunar construction tasks. Students benefit from participating and having their work evaluated by NASA and private sector engineers, technicians and educators. NASA benefits by assessing student designs and data the same way it does for its own designs, encouraging innovation in student designs and identifying clever solutions to the many challenges inherent in future Artemis missions.

“NASA’s Artemis program is our plan to return humanity to the surface of the moon in a way that is sustainable over the long term.  And the task of robotically building berm structures will be important for preparation and support of crewed lunar missions.  These competing teams are not only building critical engineering skills that will assist their future careers, but they are literally helping NASA prepare for our future Artemis missions,” says NASA Software Developer & In-Situ Resource Specialization (ISRU) Researcher Kurt Leucht.

Founded to help fuel talent for the nearby space industry, 鶹ӳý continues to build its reputation as SpaceU. NASA, with more than 50 years of research support from 鶹ӳý, has advanced its Artemis program with the goal of establishing a sustainable human presence on the moon and preparing for missions to Mars. Prominent 鶹ӳý space researchers are actively engaged in multiple collaborations with NASA — particularly within the Artemis program — and 29% of Kennedy Space Center employees are 鶹ӳý alums.

“Students are taking on a challenge that also faces all of our top space agencies and companies — how can we design and build an autonomous vehicle that can reliably perform tasks on the surface of the moon?” says Julie Brisset, interim director of ’s Florida Space Institute. “The hands-on experience is invaluable for students and will help set them up for success on their campuses and in their future careers.”

Soil simulants used in the Lunabotics Challenge at 鶹ӳý are created from crushed minerals. Once produced by ’s Exolith Lab, this regolith is now manufactured by a successful spinoff company, Space Resource Technologies. Other sponsors include Allen & Company, Lunar Outpost, Riegl USA and Venturi Astrolab.

As for the 鶹ӳý Team, comprised of nine mechanical engineering and computer science students, learning how to work together as a team was as worthwhile an output as the lunar robot itself.

“Our ‘move fast and break things’ mindset has led to lots of creativity flowing to solve problems that came up with the design,” says Lee Marshall, who serves as team lead for 鶹ӳý.

Their biggest challenge was creating a custom mechanical solution from scratch for the controls, according to Marshall. For the robot rover, materials came from 3D printers, an Xbox Connect being used as a camera and depth sensor, and other materials found in the Robotics Club lab.

“From observing the team, you can see their dedication, innate drive and determination to make it through the qualifying event,” says Crystal Maraj, faculty advisor for the 鶹ӳý Robotics Club and an assistant professor with the Institute for Simulation and Training. “It takes a lot of time and effort, and I applaud these students for their success to iterate the design and utility of the robot for competition.”

Members of the public will be able to watch the competition rounds of the Lunabotics Challenge on the Florida Space Institute’s YouTube Channel. The Lunabotics .

鶹ӳý Research Blasts Into Space Aboard Blue Origin’s New Shepard Rocket /news/ucf-research-blasts-into-space-aboard-blue-origins-new-shepard-rocket/ Tue, 19 Dec 2023 18:37:37 +0000 /news/?p=138638 The experiments aim to enhance understanding of bone loss in space, how dust behaves in microgravity, and how seismic waves and shaking impact asteroids.

]]>
When the Blue Origin space flight blasted off on Dec. 19, it carried three 鶹ӳý-led research studies aimed at keeping astronauts and equipment safe, and understanding the formation of our solar system.

This is the sixth time 鶹ӳý has had experiments fly aboard New Shepard, with previous flights in August 2021, January, May and December of 2019 and April 2016. The studies are among several dozen research payloads on NS-24, New Shepard’s 24th mission.

Bone Loss in Space

鶹ӳý College of Medicine biomedical engineer Melanie Coathup is partnering with Michael Kinzel, an associate professor in ’s Department of Mechanical and Aerospace Engineering, to understand how the absence of gravity in space impacts the bones of space travelers.

“When you’re in microgravity, there’s a change in characteristics of fluid flow and we’re trying to find out if that includes the fluid flow in our bodies, particularly through our bones,” says Coathup, who heads ’s Biionix faculty cluster initiative, an interdisciplinary team developing innovative materials, processes, and interfaces to support health and well-being.

Microgravity-induced bone loss is a health risk for space travelers and long-term goals of human space exploration and colonization. NASA research has shown that astronauts who stay in space for extended periods can lose up to 1% to 2% of bone density per month, primarily in weight-bearing bones like the spine, hips and legs. That compares to bone loss of 0.5% to 1% per year in aging men and post-menopausal women on Earth. This significant bone loss can place space travelers at risk for bone fracture and an early-onset spaceflight-induced osteoporosis.

Coathup theorizes that while on Earth, gravity exerts a constant mechanical load to the skeletal system whenever we sit, walk or stand, which causes a tiny amount of fluid to flow in and out of bones.

“On Earth, when we bear weight on our bones, it forces fluid into the tissue and then as we take off the ground, water draws back out. So that applies a mechanical stimulus to our cells that sends nutrients into the bone and then removes waste products as well,” Coathup says.

“We predict that in microgravity, in the absence of weight-bearing, there’s very little fluid movement, which stops or reduces that mechanical stimulus that sends nutrients in and stops waste products from going out and we believe this may contribute to bone damage,” she says.

This New Shepard mission does not have crew, but human subjects are highly complex and difficult to understand. So, the 鶹ӳý researchers are combining medical and mechanical engineering technology to develop novel models that directly focus the study of human bone behavior to fluidic character in microgravity. Coathup is gathering the small-scale porous structure of bones using medical technology (CT Scans). These geometries are being used by Kinzel’s group to create a microfluidic chip to represent this geometry. These microfluidic chips are miniature flow channels that include artificial capillaries using advanced 3D printing technology. Fluid and tiny beads are pumped through the chip to mimic the proteins and solutes in blood. The goal is to develop comparisons of the flow in these bone-like chips in microgravity to the behavior in various orientations in normal gravity on Earth.

“We expect to see that the presence of gravity enhances micro-scale mixing needed to support healthy bones,” Kinzel says.

The experiment is not a perfect representation of a real bone, but rather a simplified model to help researchers understand mechanisms. The size of the beads and capillaries are much larger in the experiment than in people’s bodies.

“To accommodate this, we plan to use high-end computational modeling to scale down the experiment to a real human bone,” Kinzel says.

Kinzel, an expert in computational fluid dynamics, leads the team that is creating the microchip and its platform.

The overall study is led by imec, an international nano- and digital technology research organization. The study is primarily focused on demonstrating imec’s lens-free microscope technology in a space environment. 鶹ӳý and imec collaborated to formulate research questions to demonstrate the added value of these new microscopes, which are both smaller and lighter than conventional ones, for future biological testing on the International Space Station.

Coathup has dedicated much of her research to figuring out how bones are impacted by aging and environmental stressors such as space flight, and is working on developing new technologies and therapies that can protect, repair or rebuild damaged bones.

Her collaboration with Kinzel is one of numerous payloads on this flight funded by NASA primarily through the NASA Flight Opportunities program. These payloads are helping researchers better understand the capabilities of living and working in space.

Dust Behavior in Microgravity

This project — titled Electrostatic Regolith Interaction Experiment (ERIE) — examines charged dust behavior in microgravity and also tests sensors that will characterize the charging behavior of dust in a lunar-like environment.

Key to these experiments is the several minutes of microgravity provided by the Blue Origin flight.

The research is led by Adrienne Dove, an associate professor in ’s Department of Physics, in collaboration with researchers at NASA’s Kennedy Space Center.

The sensors are being developed by collaborators at Kennedy to be used on lunar missions, such as on rover wheels, where they could measure charge on dust grains in natural lunar environments.

The results can inform strategies to keep lunar dust from damaging electronics, solar cells and mechanical equipment, and even human suits and systems during lunar missions.

The research is funded through NASA’s Flight Opportunities Program within its Space Technology Mission Directorate.

Seismic Wave Propagation in Asteroids

This project, titled Microgravity Experiment for the Speed of Sound (MESS), is examining how seismic waves and shaking can modify the surface and interior of an asteroid, and impact-induced seismicity can dictate surface features as well as overall shape and compactness changes within the asteroid.

The research is led by Julie Brisset, a research scientist and interim director of the Florida Space Institute (FSI) at 鶹ӳý. Brisset researches dust behavior under microgravity conditions for the study of planet formation and regolith.

This work is important since the mechanical structure and dynamical behavior of small asteroids can retain clues to the early processes taking place during planet formation times.

In this experiment, simulated asteroid granular material that had been placed into three separate containers has sound waves generated into them, and their speeds are recorded while in the microgravity environment of the New Shepard rocket.

Three types of asteroid material simulant are used in the experiment: fine grains (about 0.1 millimeter), millimeter-, and centimeter-sized grains.

These simulants are routinely prepared at principal investigator Brisset’s lab at ’s Florida Space Institute.

Undergraduate students assembled the payload, and over the course of its design and implementation, a total of about 10 undergraduate students participated for a project duration of five semesters, with graduating students training new arrivals on the team.

“Students were not only trained in hands-on skills in their respective areas of expertise and integrated teamwork, but also in mentoring and project management as well,” Brisset says. “They learned to handle deadlines and project documentation, and overall, had an exceptional experience preparing them for their post-graduation professional life.”

Researchers’ Backgrounds

Coathup received her doctorate in orthopedic implant fixation from University College London and joined 鶹ӳý in 2017. Before coming to 鶹ӳý, she worked at the University College of London for 17 years. Her work includes the development of a novel synthetic bone substitute material Inductigraft to boost bone repair and regeneration, which is mainly used in spinal fusion surgery and marketed by Baxter Healthcare. Her research excellence has been recognized internationally through her publications and through receiving several prestigious UK, European and international prizes from her peers.

Kinzel received his doctorate in aerospace engineering from Pennsylvania State University and joined 鶹ӳý in 2018. In addition to being a member of ’s Department of Mechanical and Aerospace Engineering and a part of ’s College of Engineering and Computer Science, he also works with ’s Center for Advanced Turbomachinery and Energy Research.

Dove received her doctorate in astrophysical and planetary sciences from the University of Colorado at Boulder and her bachelor’s degree in physics and astronomy from the University of Missouri. She joined ’s Department of Physics, part of the College of Sciences, in 2012. In 2017 Dove was awarded the Susan Niebur Early Career Award by the NASA Solar System Exploration Virtual Research Institute (SSERVI) for her contributions to the science and exploration communities. She has also received ’s Reach for the Stars Award and Luminary Award.

Brisset earned her master’s degrees in aerospace engineering in 2005 from the Institut Supérieur de l’Aéronautique et de l’Espace in Toulouse, France, and the Technical University of Munich. After working for several years as an aerospace engineer on European Space Agency International Space Station payload operations, she started graduate studies in astrophysics at the University of Braunschweig, Germany and received her doctoral degree in 2014.

Blue Origin Launch Marks 鶹ӳý’s Fourth Flight into Space This Year /news/blue-origin-launch-today-marks-ucfs-fourth-flight-space-year/ Thu, 02 May 2019 20:49:45 +0000 /news/?p=96636 鶹ӳý research continues to fly into space at a pace that is keeping with the university’s reputation as a leader in space technology and planetary science.

]]>
The successful flight of Blue Origin’s New Shepard rocket this morning from west Texas carried multiple research payloads, including one from the 鶹ӳý. It marks the fourth flight into space for the university in the past year.

One special guest flew aboard the flight today – a small plush Citronaut, affectionately referred to as Dave. The Citronaut, which is a blend of an orange and an astronaut, is ’s retro, unofficial first mascot from when 鶹ӳý was known as Florida Technological University. He’s become a beloved throwback figure among the Knight Nation.

“Dave came out with me last time to see the launch, and everyone loved him so we arranged it so that he could fly in the payload this time,” says Adrienne Dove, an assistant professor in ’s Department of Physics whose research was aboard the flight. “We strapped him in with a little zip-tie harness, and he should be visible in one of our video cameras, so we’ll get to see how he does in flight.”

The experiment aboard Blue Origin’s New Shepard vehicle is named Strata-S1 and is designed to analyze planetary surface particle distribution in low gravity.

A similar experiment is slated to fly aboard SpaceX’s Falcon 9 rocket, which is scheduled to launch soon from Kennedy Space Center on a commercial resupply mission to the International Space Station.

Whereas Strata-S1 was a one-time experiment performed while the New Shepard rocket was in space, the SpaceX flight will send Dove’s research to the ISS where her experiments will be carried out to better understand how surfaces found on planetary bodies, such as asteroids, behave in low-gravity environments.

It will be the first set of experiments to fly on a new ISS research facility named Hermes. The experiments specifically will examine how different sizes and types of particles become distributed when gravity is low.

[Assistant Professor Adrienne Dove’s] research heavily involved students, offering them real-world experience and prestigious projects to add to their resumes.

“It’s similar to the Brazil nut effect,” Dove says. “If you have a container of mixed nuts –   peanuts, cashews and Brazil nuts – the Brazil nuts always come to the top. We think it’s dependent on gravity, so this experiment is trying to understand that but with realistic particle sizes for asteroid surfaces and in a low-gravity environment.”

The results will be used to help inform current and future asteroid-sampling and landing missions, including NASA’s OSIRIS-REx and the Japan Aerospace Exploration Agency’s Hayabusa2 missions.

The research heavily involved students, offering them real-world experience and prestigious projects to add to their resumes.

Dove is also slated to have her research fly aboard a suborbital flight by Zero Gravity Corp. this month from Sanford, Florida. The research, titled SLOPE, will examine how landslides happen in low gravity, and the results could inform future space-surface exploratory and construction efforts.

It is funded by NASA’s Undergraduate Student Instrument Project that promotes interest in learning about and pursuing a career in science, technology, engineering and mathematics fields.

Julie Brisset, a research associate scientist in ’s also had research headed to space recently. Although the EXOS Aerospace Systems & Technologies SARGE rocket launched with her research in early March did not reach the desired altitude and microgravity was not achieved, the flight was beneficial in pinpointing ways to improve hardware, including the camera, for the next flight.

“There’s so much excitement on liftoff … but now we have to wait to get our payloads back to see the data, and it’s very nerve-racking.” – Adrienne Dove, 鶹ӳý assistant professor

Brisset’s project is designed to study how particles aggregate and collide in microgravity. EXOS is a developer and operator of reusable space vehicles and is based in Greenville, Texas.

John Quinn, chief operating officer for EXOS, says the March launch was the second reuse of the SARGE vehicle.

“Upon the next reuse, we anticipate achieving our target altitude and microgravity time with the 鶹ӳý payload on board,” Quinn says.

Dove was at the west Texas facility to view the launch. She says she will be able to take a peek at the experiment’s performance via video footage this afternoon and that full data analysis will take place later.

“There’s so much excitement on liftoff, and they do call-outs of the altitude, when we’re in microgravity, which is my science time, and then it’s really impressive to see it come back down,” Dove says. “But now we have to wait to get our payloads back to see the data, and it’s very nerve-racking.”

Dove says this was her second time watching one of the flights in person.

“It’s always fun to watch the livestream, but seeing the flight in person is very exciting,” she says.

Puerto Rico may finally see its first CubeSat launched into space, thanks to a collaboration between the Interamerican University on the island and the at the 鶹ӳý.

Interamerican aerospace engineering Professor Amilcar Rincon Charris and two of his students visited 鶹ӳý this week to consult with 鶹ӳý faculty and students about the construction of the miniature satellite called Puerto Rico CubeSat NanoRocks-2.

“We’ve been wanting to put a CubeSat into space since 2013,” Rincon said. “Now with our partnership with 鶹ӳý, we are really close.”

Rincon met FSI associate researcher Julie Brisset last year after 鶹ӳý became the lead organization managing the Arecibo Observatory in Puerto Rico. Brisset has worked on several NASA CubeSats by preparing payloads, such as the NanoRocks project, which flew on the International Space Station for more than a year.

These satellites are compact, no bigger than a bread box. CubeSats, named for their cube shape, house experiments that look at everything from the role of dust in planet formation to determining the best kind of adhesive to use in space. These satellites now launched by private and public companies as well as NASA provide scientists an inexpensive opportunity to conduct experiments in space.

“Our students are building the CubeSat itself, and Julie and her team are building the scientific payload,” Rincon said. “Once we teamed up this way, NASA approved funding as part of the Launch Opportunities program. Now we can really see this happening.”

For the Puerto Rican team, this partnership could mean the island’s first satellite in space, with a target launch date of 2020.

“We’re very excited to see this project succeed and have Puerto Rico’s first satellite in space.”

“It would be historic,” Rincon said. “We are very proud, very excited about that.”

This CubeSat, which will study the role of dust in planet formation, is another example of the kind of growing impact 鶹ӳý is having in space research, especially when it partners with other groups across the globe. to fly an experiment aboard a flight from commercial provider Blue Origin. Assistant Professor of physics Adrienne Dove is waiting to see her CubeSat launch from California next week and physics Professor Josh Colwell has another in the final stages of completion.

For Rincon, the project been a long road paved with challenges and opportunities for his students. About 40 students from Interamerican have worked on the project through the years. They include students majoring in mechanical, electrical and computer engineering as well as communications. Many of Rincon’s students have graduated and gone on to work for companies such as Honeywell and Florida Turbine Technologies, which have operations in Puerto Rico. One recent graduate is working at the Kennedy Space Center.

Currently, 15 students are working on the project.

There’s been another bonus for the current students on the project. At least two of them were able to visit Florida for the first time and 鶹ӳý aerospace engineering major Jacob Kirstein visited Puerto Rico for the first time.

Brisset and Kirstein traveled to Bayamon this summer. They shared lessons learned from ’s previous projects. This week Rincon and his students are at 鶹ӳý to go over design plans and talk about potential challenges in the construction of the new CubeSat.

“This is a great project,” Brisset said. “It’s taking advantage of strengths on both sides. Almicar and his students are working on the vehicle and we are working on the science payload where we have some expertise. The biggest winners are all our students.”

Gabriel Cascante, an electrical engineering major from Interamerican, said he’s “learning how to work in a team, but not just by doing one little part of the project. We’re involved in every part of production and learning to find solutions where there aren’t any you can find in a textbook. It’s been a fabulous experience so far.”

Cascante and classmate Alexander Matta, have been working on the project about five months. The team initially assembled in August 2017 after hearing about Rincon’s project, but Hurricane Maria put a stop to everything, at least for a while.

“It was a major interruption,” Matta said. “We didn’t have electricity, water, nothing. I personally didn’t have light until a few days before New Year’s. Everything kind of stopped. But we’re so glad we’re back on track now. And having the opportunity to come here to exchange ideas has been good.”

Rincon said he builds an environment in his classroom and lab that mimics a company at which students are split into teams and given assignments. This 鶹ӳý collaboration adds an international dimension to the realistic environment necessary to ensure his students can land jobs after earning their degrees, he said.

“We’ve been very successful,” Rincon said. “And we’re very excited to see this project succeed and have Puerto Rico’s first satellite in space. I can’t wait to see where we go next.”

鶹ӳý students are benefitting, too. Students who have worked on previous CubeSat projects have gone onto land jobs with NASA, the agency’s Jet Propulsion Laboratory and many private space companies.

“鶹ӳý is in the right place at the right time,” said Colwell. “There’s been big development of private providers and the demand for small satellites is exploding. I think we are very well positioned to ride the wave of opportunities to make an impact in space exploration and to develop new technology.”
