SpaceX Rivals Raise Concerns about Starship-Super Heavy Coming to Florida
SpaceX’s plan to launch its monstrous Starship-Super Heavy two-stage tandem from NASA’s Kennedy Space Center caught the attention — and concern — of two rival space companies that warn federal officials the up-to-492-foot-tall rocket will be too untested, too dangerous and too potentially disruptive for the nation’s busiest spaceport and the surrounding environment. United Launch Alliance and Blue Origin — which both have significant footprints on the Space Coast and view SpaceX as direct competition — have submitted written concerns to the Federal Aviation Administration. Phil Metzger is director of the Stephen W. Hawking Center for Microgravity Research & Education at the University of Central Florida. In an email, he said he thinks the ULA statement about Starship is fair, because it asks the FAA to do its job while noting potential impacts on the environment, neighboring communities, and launch operations of other companies at the Cape. “They noted that it is in the national interest to have multiple healthy launch companies for assured access to space so the operations of one company should not shut down its competitors. I think this is all legitimate and should be emphasized,” Metzger said. However, he said he thinks Blue Origin made “a serious mistake” by suggesting a cap on the Starship launch rate. “This would be the least creative and least helpful solution for potential problems at the Cape,” Metzger said.

UCF Researcher Further Explores Nanotech to Improve Cancer, Disease Detection
Early discovery of debilitating diseases such as cancer or dementia is critical in determining treatment and saving lives. UCF Department of Chemistry Associate Professor Xiaohu Xia recently received a $1.3 million R01 grant from the National Institutes of Health to continue his promising nanoparticle research that could drastically improve disease detection accuracy by more than 300-times. The NIH awards R01 grants to investigators for mature research projects that are hypothesis-driven with strong preliminary data like Xia's. "In our preliminary laboratory results, we have demonstrated that our nanoparticle-based artificial enzymes are able to improve the detection sensitivity by about 300 times better than the current assets in the market," he says. His research spans four years, and it focuses on enhancing the diagnostic efficacy of enzyme-linked immunosorbent assay (ELISA) testing by using specially tailored nickel-platinum nanoparticles that will bind to specific disease biomarkers – such as proteins and hormones – in bodily fluid samples. Xia is the sole principal investigator, but he will oversee postdoctoral and graduate students who will assist him. Although there has been some experimentation with substituting nanoparticles in ELISA testing, there hasn't been a monumental advancement in diagnostic sensitivity in decades, and Xia says he aims to make the leap through his nanoparticle research.

What Will Emerge from the Wreckage of the Arecibo Telescope?
In a corner of his laboratory, Professor Abel Méndez, director of the Planetary Habitability Laboratory at the University of Puerto Rico, keeps one of his most cherished mementos related to the Arecibo radio telescope. Simple sheets of paper hanging on the wall show the schedule where astronomers and scientists from all over the world were assigned blocks of two to four hours to use the telescope and listen to the universe. Méndez’s initials are still there: AM. For more than 50 years, Arecibo was the world’s largest single-dish telescope. And starting in 2017, Méndez made frequent visits to the Arecibo Observatory, about a 30-minute drive from the university, to focus on the stars. His goal? To explore the habitability of exoplanets. “There are stars that are very active, such as red dwarfs, and others like the sun, which you could say are rather quiet,” he says. “I used the radio telescope to observe which stars were the most stable because those are the ones that planets with a more habitable atmosphere are likely to be around,” he adds. In part, Arecibo helped him understand what to prioritize in his research. Until December 1, 2020, when the telescope collapsed. Luisa Fernanda Zambrano, a Colombian planetary scientist who had observed and classified asteroids with the Arecibo radio telescope since 2013, remembers that painful day: “I cried, my team cried, we were all crying,” she says from her office in the United States, where she works with the Florida Space Institute at the University of Central Florida.
