Could China Beat America in the Race to Get Boots Back on the Moon?

Call it a matter of pride, national security or a desire for astronomical dominance; there's a sense of urgency within the U.S. government to return to the moon, sparked by China's team of taikonauts, who could land there before American astronauts get back to the lunar surface. The latest space race is a topic that is making national news. Florida Tech's experts are lending their opinions and insights about the likelihood of a lunar return, and what it might mean. NASA, with the urging of many politicians, has been racing to get astronauts back to the moon — before the Chinese land taikonauts on the lunar surface. But what’s the rush to return to a place the United States has already been and left 53 years ago? Especially when Mars looms as an enticing option for interplanetary travel. Space experts say there’s plenty of reasons for the urgency: national pride and national security. But also returning to the moon and building habitats would mean long term dominance in space and ensure access to resources that NASA didn’t know where there when the Apollo missions flew. Now with the Chinese making significant progress in human space exploration, the clock is ticking. “The Chinese in the last 20 years have made amazing strides in all aspects of space. They’re sending robots to the moon on a very regular basis. Now they’re doing some pretty amazing activities even on the far side of the moon, and they have a Chinese space station now in Earth orbit,” said Don Platt, associate professor of space systems at Florida Tech. Can China beat NASA to the moon? “The Chinese have really caught up,” said Platt. “I do believe that the Chinese are definitely advancing their efforts on the moon, and are identifying it as a critical aspect of their strategic future in space." When asked about the prospect of Chinese astronauts making it to the moon before NASA's planned Artemis III mission, Platt said he believes it’s a possibility and he cited the efforts China is making to highlight the importance of the nation's space efforts to its own populace. “They have some amazing videos. They’re really engaging the Chinese public, and really using it to do what what we’ve always done in space, and that is to inspire the next generation and to show the world the technical abilities of the Chinese,” said Platt.  May 21 - USA Today The race is on, and it's getting a lot of attention.

NASA Asks Researchers to Help Define Trustworthiness in Autonomous Systems

A Florida Tech-led group of researchers was selected to help NASA solve challenges in aviation through its prestigious University Leadership Initiative (ULI) program. Over the next three years, associate professor of computer science and software engineering Siddhartha Bhattacharyya and professor of aviation human factors Meredith Carroll will work to understand the vital role of trust in autonomy. Their project, “Trustworthy Resilient Autonomous Agents for Safe City Transportation in the Evolving New Decade” (TRANSCEND), aims to establish a common framework for engineers and human operators to determine the trustworthiness of machine-learning-enabled autonomous aviation safety systems. Autonomous systems are those that can perform independent tasks without requiring human control. The autonomy of these systems is expected to be enhanced with intelligence gained from machine learning. As a result, intelligence-based software is expected to be increasingly used in airplanes and drones. It may also be utilized in airports and to manage air traffic in the future. Learning-enabled autonomous technology can also act as contingency management when used in safety applications, proactively addressing potential disruptions and unexpected aviation events. TRANSCEND was one of three projects chosen for the latest ULI awards. The others hail from Embry-Riddle Aeronautical University in Daytona Beach – researching continuously updating, self-diagnostic vehicle health management to enhance the safety and reliability of Advanced Air Mobility vehicles – and University of Colorado Boulder – investigating tools for understanding and leveraging the complex communications environment of collaborative, autonomous airspace systems. Florida Tech’s team includes nine faculty members from five universities: Penn State; North Carolina A&T State University; University of Florida; Stanford University; Santa Fe College. It also involves the companies Collins Aerospace in Cedar Rapids, Iowa and ResilienX of Syracuse, New York. Carroll and Bhattacharyya will also involve students throughout the project. Human operators are an essential component of aviation technology – they monitor independent software systems and associated data and intervene when those systems fail. They may include flight crew members, air traffic controllers, maintenance personnel or safety staff monitoring overall system safety. A challenge in implementing independent software is that engineers and operators have different interpretations of what makes a system “trustworthy,” Carroll and Bhattacharyya explained. Engineers who develop autonomous software measure trustworthiness by the system’s ability to perform as designed. Human operators, however, trust and rely on systems to perform as they expect – they want to feel comfortable relying on a system to make an aeronautical decision in flight, such as how to avoid a traffic conflict or a weather event. Sometimes, that reliance won’t align with design specifications. Equally important, operators also need to trust that the software will alert them when it needs a human to take over. This may happen if the algorithm driving the software encounters a scenario it wasn’t trained for. “We are looking at how we can integrate trust from different communities – from human factors, from formal methods, from autonomy, from AI…” Bhattacharyya said. “How do we convey assumptions for trust, from design time to operation, as the intelligent systems are being deployed, so that we can trust them and know when they’re going to fail, especially those that are learning-enabled, meaning they adapt based on machine learning algorithms?” With Bhattacharyya leading the engineering side and Carroll leading the human factors side, the research group will begin bridging the trust gap by integrating theories, principles, methods, measures, visualizations, explainability and practices from different domains – this will build the TRANSCEND framework. Then, they’ll test the framework using a diverse range of tools, flight simulators and intelligent decision-making to demonstrate trustworthiness in practice. This and other data will help them develop a safety case toolkit of guidelines for development processes, recommendations and suggested safety measures for engineers to reference when designing “trustworthy,” learning-enabled autonomous systems. Ultimately, Bhattacharyya and Carroll hope their toolkit will lay the groundwork for a future learning-enabled autonomous systems certification process. “The goal is to combine all our research capabilities and pull together a unified story that outputs unified products to the industry,” Carroll said. “We want products for the industry to utilize when implementing learning-enabled autonomy for more effective safety management systems.” The researchers also plan to use this toolkit to teach future engineers about the nuances of trust in the products they develop. Once developed, they will hold outreach events, such as lectures and camps, for STEM-minded students in the community.

Life Beyond Earth? Florida Tech's Expert's are Hoping SPHEREx Will Have The Answer

In March, NASA's SPHEREx — short for Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer — was launched to the skies and far into space. Its mission has received plentiful media coverage but demands the expert analysis of scholars like astrobiologist Manasvi Lingam, an assistant professor of aerospace, physics and space sciences at the Florida Institute of Technology.  The space telescope is designed to [operate] with unmatched clarity, gathering a big-picture view that will help scientists tackle questions about the origin of the universe itself, the galaxies within and life's essential ingredients wafting in our home galaxy, the Milky Way. While scientists have previously detected lots of complex organic molecules in the interstellar medium and protoplanetary disks, "we still do not know a lot about the actual abundances of useful building blocks," astrobiologist Manasvi Lingam of the Florida Institute of Technology told Space.com. That means scientists don't have strong constraints about how efficiently frozen water molecules are transferred from interstellar clouds to protoplanetary disks, where they would eventually be incorporated into newborn planets, he said. "This mission can improve the data, and help make better forecasts about the probability of the origin of life on those worlds."

NASA Grant Funds Research Exploring Methods of Training Vision-Based Autonomous Systems

Conducting research at 5:30 a.m. may not be everybody’s first choice. But for Siddhartha Bhattacharyya and Ph.D. students Mohammed Abdul, Hafeez Khan and Parth Ganeriwala, it’s an essential part of the process for their latest endeavor. Bhattacharyya and his students are developing a more efficient framework for creating and evaluating image-based machine learning classification models for autonomous systems, such as those guiding cars and aircraft. That process involves creating new datasets with taxiway and runway images for vision-based autonomous aircraft. Just as humans need textbooks to fuel their learning, some machines are taught using thousands of photographs and images of the environment where their autonomous pupil will eventually operate. To help ensure their trained models can identify the correct course to take in a hyper-specific environment – with indicators such as centerline markings and side stripes on a runway at dawn – Bhattacharyya and his Ph.D. students chose a December morning to rise with the sun, board one of Florida Tech’s Piper Archer aircraft and photograph the views from above. Bhattacharyya, an associate professor of computer science and software engineering, is exploring the boundaries of operation of efficient and effective machine-learning approaches for vision-based classification in autonomous systems. In this case, these machine learning systems are trained on video or image data collected from environments including runways, taxiways or roadways. With this kind of model, it can take more than 100,000 images to help the algorithm learn and adapt to an environment. Today’s technology demands a pronounced human effort to manually label and classify each image. This can be an overwhelming process. To combat that, Bhattacharyya was awarded funding from NASA Langley Research Center to advance existing machine learning/computer vision-based systems, such as his lab’s “Advanced Line Identification and Notation Algorithm” (ALINA), by exploring automated labeling that would enable the model to learn and classify data itself – with humans intervening only as necessary. This measure would ease the overwhelming human demand, he said. ALINA is an annotation framework that Hafeez and Parth developed under Bhattacharyya’s guidance to detect and label data for algorithms, such as taxiway line markings for autonomous aircraft. Bhattacharyya will use NASA’s funding to explore transfer learning-based approaches, led by Parth, and few-shot learning (FSL) approaches, led by Hafeez. The researchers are collecting images via GoPro of runways and taxiways at airports in Melbourne and Grant-Valkaria with help from Florida Tech’s College of Aeronautics. Bhattacharyya’s students will take the data they collect from the airports and train their models to, in theory, drive an aircraft autonomously. They are working to collect diverse images of the runways – those of different angles and weather and lighting conditions – so that the model learns to identify patterns that determine the most accurate course regardless of environment or conditions. That includes the daybreak images captured on that December flight. “We went at sunrise, where there is glare on the camera. Now we need to see if it’s able to identify the lines at night because that’s when there are lights embedded on the taxiways,” Bhattacharyya said. “We want to collect diverse datasets and see what methods work, what methods fail and what else do we need to do to build that reliable software.” Transfer learning is a machine learning technique in which a model trained to do one task can generalize information and reuse it to complete another task. For example, a model trained to drive autonomous cars could transfer its intelligence to drive autonomous aircraft. This transfer helps explore generalization of knowledge. It also improves efficiency by eliminating the need for new models that complete different but related tasks. For example, a car trained to operate autonomously in California could retain generalized knowledge when learning how to drive in Florida, despite different landscapes. “This model already knows lines and lanes, and we are going to train it on certain other types of lines hoping it generalizes and keeps the previous knowledge,” Bhattacharyya explained. “That model could do both tasks, as humans do.” FSL is a technique that teaches a model to generalize information with just a few data samples instead of the massive datasets used in transfer learning. With this type of training, a model should be able to identify an environment based on just four or five images. “That would help us reduce the time and cost of data collection as well as time spent labeling the data that we typically go through for several thousands of datasets,” Bhattacharyya said. Learning when results may or may not be reliable is a key part of this research. Bhattacharyya said identifying degradation in the autonomous system’s performance will help guide the development of online monitors that can catch errors and alert human operators to take corrective action. Ultimately, he hopes that this research can help create a future where we utilize the benefits of machine learning without fear of it failing before notifying the operator, driver or user. “That’s the end goal,” Bhattacharyya said. “It motivates me to learn how the context relates to assumptions associated with these images, that helps in understanding when the autonomous system is not confident in its decision, thus sending an alert to the user. This could apply to a future generation of autonomous systems where we don’t need to fear the unknown – when the system could fail.” Siddhartha (Sid) Bhattacharyya’s primary area of research expertise/interest is in model based engineering, formal methods, machine learning engineering, and explainable AI applied to intelligent autonomous systems, cyber security, human factors, healthcare, explainable AI, and avionics. His research lab ASSIST (Assured Safety, Security, and Intent with Systematic Tactics) focuses on the research in the design of innovative formal methods to assure performance of intelligent systems, machine learning engineering to characterize intelligent systems for safety and model based engineering to analyze system behavior.

Space suit experiment lands on the moon

University of Delaware research made a moon landing on Sunday along with other experiments aboard the unmanned Blue Ghost spacecraft. These projects will help scientists better understand what it will take to successfully land humans on the moon, and could possibly pave the way for an extended stay. The experiment led by UD researcher Norman Wagner and his company STF Technologies, LLC, aims to determine how moon dust particles stick to different materials exposed to the moon’s environment. These particles, called regolith, are fine and very sharp, similar to volcanic rock or dust found on Earth. Prototype spacesuit materials made by UD and STF Technologies will be tested for their ability to repel this moon dust in experiments strapped outside a lunar lander designed to carry payloads to the moon’s surface. The UD spacesuit shell textiles are treated with multiple nanotechnologies, including shear thickening fluid, a revolutionary material co-developed by UD and STF Technologies that normally behaves like a liquid, but becomes a solid under impact, a useful feature when puncture resistance is a priority. The hope is that beyond puncture protection, the STF-infused spacesuit textiles will offer greater dust deterrence, increasing the material’s lifespan in space. Other RAC experiments will test materials for solar cells, optical systems, coatings and sensors. In other related work, the Wagner lab currently has experiments aboard the International Space Station (ISS) through a NASA collaboration to develop new construction materials for lunar exploration. These ISS experiments, part of a Materials International Space Station Experiment (MISSE) that launched last November, extend Wagner’s previous work on ways to make concrete in space, for such items as rocket landing pads, buildings, roads, habitats and other structures. More recent work in the Wagner lab by undergraduate researchers and doctoral students focuses on methods for curing 3D-printed materials in space, including using microwave technology. “Here we aren’t trying to get rid of the moon dust — we are trying to leverage it to create extraterrestrial cement through additive manufacturing on the moon,” said Wagner, Unidel Robert L. Pigford Chair in the Department of Chemical and Biomolecular Engineering. Contact mediarelations@udel.edu to set up an interview.

The ISS is Leaking! What Happens Now? Florida Tech's Don Platt Can Explain

There's an issue on the International Space Station (ISS) that is becoming a growing concern for both the Russian and American space programs. The ISS is leaking, and the matter is rightfully getting attention from media around the world. The reporters looking for answers are connecting with Florida Tech's Don Platt to explain what exactly is happening and what it means for the future of this $100 billion facility. Dr. Platt's work has involved developing, testing and flying different types of avionics, communications and rocket propulsion systems. He teaches about space systems. The problem exemplifies how NASA is contending with aging but critical space infrastructure: The orbiting laboratory, with a living area larger than a six-bedroom house, is the agency's only way to learn about health impacts to astronauts, develop or test life support systems for future missions, and advance a plethora of space technologies. NASA wants to keep it running until 2030 — but doing so will require constant surveillance and, literally, patching. "It's an old station, and it has done some amazing things," Don Platt, an associate professor of space systems at Florida Tech, told Mashable. Mashable, Nov. 19 Local television and national networks like NPR were also seeking Platt's expert insights. NASA and Russian space officials are at odds over the significance of a long-standing air leak aboard the International Space Station. The leak, originating from a Russian module, has reportedly persisted for about five years. Don Platt, an associate professor at the Florida Institute of Technology, explained the potential risks. “There’s definitely concerns about this leak and the potential for it to get worse over time,” Platt said. While NASA views the issue as a serious safety concern, Moscow insists the situation is under control and the module is safe. “NASA is quite concerned about it, and the Russians are more or less saying, ‘We have it under control. Don’t worry about it,’” Platt said. The affected module is one of the oldest on the station, having been operational for more than 20 years. “One of the Russian modules on the space station, one of the oldest, is starting to lose some of the air that astronauts need to breathe,” he said.  November 18 - NBC News The coverage featuring Platt's insight is also being carried by Russian media and news sites.

Florida Tech, Kennedy Space Center to Study Waste Treatment in Space

Associate professor of chemical engineering Toufiq Reza has spent years researching sustainable waste conversion techniques on Earth. When Florida Tech offered him a sabbatical, he took the chance to learn what that conversion process looks like in outer space while further strengthening the university’s already deep ties to NASA. In Fall 2023, Reza became the first professor to leverage school funding to spend a semester at NASA’s Kennedy Space Center. He worked with Annie Meier, who leads a team developing ways to convert astronaut-generated trash into fuel during missions, known as in-situ resource utilization (ISRU). “I wanted to do something different that I haven’t done. I have been doing research in my field; I know who the players are,” Reza said.” I could have easily gone to a research lab at another university and continued my research. But I wanted to learn something new.” His sabbatical prompted a new partnership between NASA Kennedy and Florida Tech. This summer, they signed an annex to their existing Space Act Agreement which will allow Kennedy Space Center (KSC) and the university to conduct joint research regarding logistical waste treatment and ISRU. “At NASA, we want researchers who are doing something that could help us, that could be synergistic, and to not reinvent the wheel,” said Jose Nuñez, university partnerships and small sat capabilities manager at NASA Kennedy. “The goal is to find professors who can benefit the agency in an area that needs more research.” As part of the agreement, KSC will share raw materials, waste simulant samples and information such as gas composition data with Florida Tech. In return, the university will analyze and share findings, such as what useful products can be taken from trash-to-gas waste for use as plant nutrients, and evaluate value-added applications. “I will encourage students to work on some of their technologies, test them in our lab and vice versa. This is a massive thing,” Reza said. “We can learn from each other to help each other.” Already, Reza’s students have visited Meier’s lab, and Meier and her KSC team came to Florida Tech to present her research and visit the university’s research facilities. Meier’s goals are similar to Reza’s: Both researchers want to find sustainable ways to convert trash and waste into energy, materials and chemicals. However, the methods aren’t completely transferrable between the two different environments of Earth and space. On Earth, Reza explained, waste can be burned or stored in a landfill. Neither of those options are viable in space. “You cannot dig up the moon soil and start burying. There is no oxygen or air to actually burn it…there is no water,” Reza explained. Currently, astronaut waste, such as food packaging, clothing, hygiene items and uneaten food, is launched back towards Earth and incinerates on the way there. However, Meier is working to advance waste mitigation technology, which Reza got to see up close. One of her projects, the Orbital Syngas/Commodity Augmentation Reactor (OSCAR), mixes oxygen, heat and trash in a reactor, which burns the trash and collects the gas it creates. Over the course of the semester, Reza assisted in KSC’s Applied Chemistry Lab, where Meier’s research took place. He offered both expertise and extra hands, from helping measure samples to reading through literature. He also took note of innovative technology for potential new research ideas, such as potentially developing a way of protecting metal coatings in space using the tools he learned. Meier’s waste conversion technology is built for a space environment, but Reza said it is unlikely that her complete systems could be used for waste conversion on Earth. Just as water and oxygen are limited resources in space but are plentiful on Earth, vacuums are plentiful resources in space but are expensive to create back home. However, that doesn’t stop the researchers from seeking inspiration through the new partnership. “We can learn from them and then take a part of their technology and integrate it with ours to make our technology more sustainable and vice versa,” Reza said. “They can improve their technology by utilizing part of our technology as well. As Meier said, “I wanted to learn on the terrestrial side how we can infuse some of our technology, and he wanted to learn from us to grow into the space sector, so it was a really cool match.”

New Images from Euclid Telescope Offer Powerful Complement to Hubble, JWST

Five new images from the European Space Agency’s (ESA) Euclid space telescope mission continue to further our exploration of the “Dark Universe,” according to Florida Tech observational astrophysicist Eric Perlman. With help from NASA’s Jet Propulsion Laboratory, Euclid’s mission is to grow our understanding of “dark matter” so scientists can precisely chart its presence in the universe. Photo Credit: ESA/Euclid/Euclid Consortium/NASA Euclid returned its first five images in November 2023 after launching from Cape Canaveral, Florida – just minutes from the Florida Tech campus – that summer. Now astronomers and scientists are examining a new batch released in late May. The five new images feature a star-forming region in the Milky Way galaxy, clusters of hundreds of galaxies and more stunning sights. “These are magnificent images which showcase the power of the Euclid telescope,” said Perlman, who is a professor at Florida Tech’s Department of Aerospace, Physics and Space Sciences. “The view they show of these objects is strikingly different from what other observatories, in particular Hubble and JWST, show.” NASA predicts that by 2030, Euclid will create a cosmic map that covers almost a third of the sky, thanks to the field of view that is wider than both the Hubble Telescope and the James Webb Space Telescope (JWST). Photo Credit: ESA/Euclid/Euclid Consortium/NASA Dr. Perlman is available to discuss the new images, how and why they differ from previous images, and what this means for our understanding of dark matter.

Ready for takeoff! The Starliner is set for its first mission to the ISS

Since 2011, any American astronaut looking to get to or from the International Space Station (ISS) had to lift off from the Baikonur Cosmodrome, a spaceport operated by Russia within Kazakhstan. It was the only way to get up into space - for now. It's why almost a decade ago private sector companies Boeing and SpaceX were engaged by NASA to develop a new way to get to the ISS from American soil.  All of that is about to change, and all eyes have been on Boeing's Starliner as it readies to take flight with a crew for the first time. Florida's Tech's Don Platt , the Director of the Spaceport Education Center, has also been busy as the media coverage has been intense. “In this case, NASA is truly buying a service and it’s up to the company to get it all right. With just some oversight," said Don Platt, of Florida Tech. Starliner rolled out to Launch Complex 41 in the early morning on Tuesday. It will be positioned atop a ULA Atlas 5 rocket for the planned liftoff on May 6 from the Cape Canaveral Space Force Station. As Platt explained, Starliner is a critical second option for NASA. “With all the success of SpaceX has had recently, we can’t simply rely on SpaceX to provide all services to the American space program," Platt said. This is the first flight of Starliner with a crew onboard so it’ll be the first time for it to fly in this configuration. During these test missions, there are always lessons to be learned. “We are all aware of some of the issues the Boeing company has experienced in the last couple of years. And to have a successful test flight here with astronauts onboard is a definite plus from PR aspect,” Platt said. Two seasoned NASA astronauts will be the first to take a ride in Starliner up to the ISS; Suni Williams and Barry “Butch” Wilmore. They’ll be up there for eight days on this test mission and if all goes well, the first Starliner mission on NASA crew rotation up to the ISS will come next spring. -- April 16 - NBC News Getting to the ISS, Moon and even Mars are getting a lot of attention lately.
