UCF researcher is developing algorithms to further space, sea exploration

The work will help protect spacecraft from colliding with objects like asteroids and satellites.

2024-05-20
(Press-News.org) Cislunar space, which stretches from the Earth to just beyond the moon’s orbit, is about to become heavily trafficked over the next 10 years. With NASA’s planned Artemis missions and other countries joining in the cislunar space race, there’s an interest in observing, tracking and predicting the orbit of objects like asteroids and satellites so they don’t collide with spacecraft.

But the process of detecting and observing space objects, known as space domain awareness (SDA), faces challenges with the extensive volume of cislunar space.

“Cislunar space is vast,” says Tarek Elgohary, an associate professor of aerospace engineering. “The current SDA infrastructure, which is mostly Earth-based, is not equipped to provide the needed coverage in cislunar space. There is a need for fast and accurate solutions to quantify uncertainties to improve predictions and provide SDA information in the absence of continuous coverage.”

Elgohary and his team will develop those solutions with the support of a $350,000 grant from the Air Force Office of Scientific Research Dynamic Data and Information Processing Program. They will create a computational framework to rapidly and accurately track space objects in real time, onboard spacecraft or satellites like the Air Force Research Laboratory’s Oracle, which is designed to increase SDA capabilities in cislunar space. The algorithms will allow Oracle and other spacecraft to operate autonomously without intervention from Earth.

Those same algorithms could also have an impact on maritime domain awareness (MDA). Just as spacecraft might need to identify space junk or track the orbit of a satellite, watercraft need to identify other vessels, predict target trajectories and detect suspicious behavior in real-time.

“Space and maritime domains share a lot of similarities in terms of the lack of continuous coverage of spacecraft or vessels, the large size of the search domain, and the need for the capability to predict maneuvers,” Elgohary says. “Maritime domain awareness may require shorter time scales; however, with the expansion of space missions, space domain awareness operations have been reduced from weeks and days to hours and minutes.”

Elgohary will use his expertise in space to develop a similar computational framework for the sea. The algorithms developed for uncertainty quantifications will advance MDA and allow sea vessels to detect objects in real time and predict their future location.

This work is funded through a $150,000 grant from Lockheed Martin.

About the Researcher

Tarek Elgohary joined UCF in 2016 as an assistant professor. He manages the Astrodynamics, Space and Robotics Laboratory (ASRL) in the Department of Mechanical and Aerospace Engineering. He earned a bachelor’s degree in mechanical engineering from the American University in Cairo and a master’s degree and doctoral degree in aerospace engineering from Texas A&M University.

Illuminating neuro-vascular dynamics throughout the body: 3D-printed implants and bioluminescence duet shed light on brain–spinal interactions
2024-05-20
A sensory process such as pain is no ordinary phenomenon—it’s a symphony of neural and vascular interactions orchestrated by the brain and spinal cord. Attempting to dissect this symphony by focusing on a single region is like trying to understand a complex melody by listening to just one instrument. It’s incomplete, potentially misleading, and may result in erroneous conclusions. Enter the Carney Institute’s team of visionaries. Their mission? To develop tools that allow unprecedented observation of neural and vascular activity within the brain and spinal cord. They tackled two critical fronts: imaging hardware and bioluminescent (BL) molecular tools. Innovative ...

Studies show linked biological pathways driving skin inflammation

2024-05-20
A certain biological pathway, a set of linked reactions in the body, drives the inflammation seen in the skin disease psoriasis, a new study finds. The work could lead to improved therapies for all inflammatory skin diseases, including atopic and allergic dermatitis and a type of boil called hidradenitis suppurativa, say the study authors. Inflammation is the body’s natural response to irritation and infection, but when out of control, it can lead to the reddish, flaky, itchy lesions that come with these skin diseases. Led by researchers at NYU Langone Health, the new study found that the interleukin-17 (IL-17) pathway, ...

Pioneering research study makes significant contributions toward addressing the shortage of suitable knee meniscus and TMJ disc replacements

2024-05-20
The shortage of suitable donor meniscus grafts from the knee and temporomandibular joint (TMJ) impedes treatments for millions of patients. Vitrification offers a promising solution by transitioning these tissues into a vitreous state at cryogenic temperatures, protecting them from ice crystal damage using high concentrations of cryoprotectant agents (CPAs). However, vitrification's success is hindered for larger tissues (>3 mL) due to challenges in CPA penetration. Dense avascular meniscus tissues require extended CPA exposure for adequate penetration; however, ...

By listening, scientists learn how a protein folds

By listening, scientists learn how a protein folds
2024-05-20
CHAMPAIGN, Ill. —  By converting their data into sounds, scientists discovered how hydrogen bonds contribute to the lightning-fast gyrations that transform a string of amino acids into a functional, folded protein. Their report, in the Proceedings of the National Academy of Sciences, offers an unprecedented view of the sequence of hydrogen-bonding events that occur when a protein morphs from an unfolded to a folded state. See video: Protein Sonification “A protein must fold properly to become an enzyme or signaling molecule or whatever its function may be — all the many things that proteins do in our bodies,” said University of Illinois ...

UC Irvine-led team uncovers ‘vigorous melting’ at Antarctica’s Thwaites Glacier

UC Irvine-led team uncovers ‘vigorous melting’ at Antarctica’s Thwaites Glacier
2024-05-20
Irvine, Calif., May 20, 2024 — A team of glaciologists led by researchers at the University of California, Irvine used high-resolution satellite radar data to find evidence of the intrusion of warm, high-pressure seawater many kilometers beneath the grounded ice of West Antarctica’s Thwaites Glacier. In a study published today in Proceedings of the National Academy of Sciences, the UC Irvine-led team said that widespread contact between ocean water and the glacier – a process that is replicated throughout Antarctica and in Greenland – causes “vigorous melting” and may require a reassessment of ...

Warm seawater speeding up melting of ‘Doomsday Glacier,’ scientists warn

2024-05-20
EMBARGOED UNTIL 15:00 EDT MONDAY, MAY 20, 2024 For the first time, there is visible evidence showing that warm seawater is pumping underneath Antarctica’s Thwaites Glacier—ominously nicknamed the Doomsday Glacier. An international team of scientists—including a researcher from the University of Waterloo—observed it using satellite imagery and warns that it could accelerate catastrophic sea level rise in 10 to 20 years.  The intrusion of seawater causes the ice to continuously lift off the land and settle back down again. Ice melts intensely when it first touches seawater, ...
