Sylvie Crowell, a materials researcher at NASA’s Glenn Research Center in Cleveland, has received a NASA Early Career Initiative (ECI) award for a research proposal titled “Lunar Dust Reduction through Electrostatic Adhesion Mitigation (L-DREAM).” The research focuses on developing a passive lunar dust mitigation coating for solar cells and thermal control surfaces. 

Operated under the NASA Space Technology Mission Directorate, the award will fund Crowell’s research in fiscal year 2026, beginning Oct. 1, 2025.  

NASA’s ECI is a unique opportunity for the best and brightest of NASA’s early career researchers to lead hands-on technology development projects. The initiative aims to invigorate NASA’s technological base and best practices by partnering early career NASA leaders with external innovators.

Thousands of baseball fans travel across the country annually to watch teams compete in Omaha, Nebraska, during the NCAA Men’s College World Series in June. This year, NASA’s Glenn Research Center in Cleveland swung for the fences to celebrate the city’s Diamond Anniversary of hosting the event and to highlight the intersections of sports and STEM.

As part of a larger outreach program across the region, NASA Glenn, the only NASA center in the Midwest, continues to meet audiences where they are to make space relatable to all.  

“We brought NASA to Omaha during the College World Series to connect with a broader audience through one of the country’s most celebrated sporting events,” said NASA Glenn Public Engagement Specialist Heather Brown, who led the event. “Our goal was to spark curiosity, inspire the next generation, and demonstrate how science and exploration intersect with everyday passions — like baseball.”

Situated next to the Kiewit Luminarium on the Lewis and Clark Landing of Omaha’s RiverFront, NASA Glenn engaged fans with Artemis-themed displays, interactive kiosks, a Space Launch System inflatable rocket, and the 53-foot Journey to Tomorrow traveling exhibit. In addition, Omaha-born NASA Flight Director Brandon Lloyd greeted visitors and participated in an event at the Branched Oak Observatory, where a large crowd of space enthusiasts asked questions and learned more about NASA’s missions.  

“This was an incredible opportunity to tell NASA’s story and showcase our work in a setting that was already energized and ready to engage,” Brown said.

China's Mars Mission Could Answer the Ultimate Question: Are We Alone?

Universe Today - Wed, 07/16/2025 - 7:49am

China is poised to make space exploration history again with its Tianwen-3 mission launching in 2028. With the audacious plan to drill two meters beneath Mars' radiation blasted surface it aims to collect samples that could harbor ancient microbial life, and bring them back to Earth for the first time in human history! The mission's most intriguing challenge isn't the technical feat of interplanetary sample return, it’s the quarantine protocols required once these potentially life containing samples arrive on Earth making this mission as much about protecting our planet as it is about exploring another.

A Few Bright Buildings Light Up the Entire Night Sky

Universe Today - Wed, 07/16/2025 - 7:49am

A 14year study of Hong Kong's Earth Hour participation has revealed that it's not the millions of apartment windows or office buildings that steal our night sky, but rather a small handful of brightly lit skyscrapers and LED advertising boards that have an outsized impact on darkness above cities. When these decorative lights and digital screens go dark, the night sky becomes up to 50% darker, offering a hopeful new strategy for tackling light pollution without requiring massive citywide changes. Could this be he the change that dramatically improve night sky visibility for stargazers, wildlife, and anyone hoping to reconnect with the the night sky above our urban landscapes?

Magnets Could Become the Next Generation of Gravitational Wave Detectors

Universe Today - Wed, 07/16/2025 - 7:49am

When Einstein's predicted ripples in spacetime pass through magnetic fields, they cause the current carrying wires to dance at the gravitational wave frequency, creating potentially detectable electrical signals. Researchers have discovered that the same powerful magnets used to hunt for dark matter could double as gravitational wave detectors. This means experiments already searching for the universe's most elusive particles could simultaneously capture collisions between black holes and neutron stars, getting two of physics' most ambitious experiments for the price of one, while potentially opening entirely new windows into the universe's most violent events.

These are the Most Concerning Pieces of Space Debris

Universe Today - Wed, 07/16/2025 - 7:49am

There are tens of thousands of pieces of space debris hurling around the Earth right now. Since it can cost tens of millions of dollars to remove just a single piece of space debris, which are the ones that we should be most concerned with? A few years ago, 11 teams of experts came together to rank the 50 most concerning pieces of debris, the ones that they think would be the highest priority. Although they used different approaches, 20-40% of the objects ended up on several experts' lists.

How human eggs stay fresh for decades
