If you’re in the path of totality for the April 8 total solar eclipse, you’ll experience a brief period of darkness — totality — for a few seconds or minutes. This is the only safe time to look directly at the sun without solar eclipse glasses. If you observe the sun‘s corona during totality, you may see dark-pink towers and loops of electrically charged plasma stretching many times the diameter of Earth into space. During the last total solar eclipse, in Australia on April 20, 2023, these “prominences” were spectacular…

The Soyuz rocket launches to the International Space Station with Expedition 71 NASA astronaut Tracy Dyson, Roscosmos cosmonaut Oleg Novitskiy, and Belarus spaceflight participant Marina Vasilevskaya, onboard, Saturday, March 23, 2024, at the Baikonur Cosmodrome in Kazakhstan. NASA/Bill Ingalls Three crew members including NASA astronaut Tracy C. Dyson successfully launched at 8:36 a.m. EDT Saturday from the Baikonur Cosmodrome in Kazakhstan to the International Space Station. Dyson, along with her crewmates Roscosmos cosmonaut Oleg Novitskiy and spaceflight participant Marina Vasilevskaya of Belarus, will dock to the space station’s Prichal module…

Scientists are tracking a massive plume of toxic gas moving across northern Europe that was spat out by the ongoing volcanic eruption in Iceland. The gas cloud is unlikely to cause any serious health problems. However, it could impact the ozone hole above the Arctic, experts warn. On March 16, an underground volcano in Icealnd’s Reykjanes Peninsula blew its top for the fourth time in as many months, opening up the largest fissure of the current eruption cycle and unleashing a massive lava flow that narrowly missed the evacuated town of Grindavík. There…
Read MoreFlight attendant becomes 1st Belarusian woman in space on ISS-bound Soyuz launch
For the first time, a spacecraft has lifted off with a flight attendant aboard, but there will be no drink service during the flight. Marina Vasilevskaya, who also served as a flight instructor for Belavia Airlines in her home country of Belarus, traded her attendant uniform for a Russian Sokol pressure suit to become the first Belarusian woman to fly into space. On Saturday (March 23), she launched on Russia’s Soyuz MS-25 spacecraft with cosmonaut Oleg Novitsky of Roscosmos and NASA astronaut Tracy Caldwell Dyson on a mission to the…

Professor Cui will use the recently established DFT/machine learning guided metals development methodology to unravel the complex relationships between compositions, crystal structures, phase transformation, and fatigue behavior of the elastocaloric materials. He will develop novel, new elastocaloric materials and use them as the basis…

1 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Manuel Quevedo-Lopez University Of Texas, Dallas ESI23 Quevedo-Lopez Quadchart.pdf Current SNSPD’s use a thin, superconducting film to detect photons. These films are highly reflective and must be made very thin, on the order of a few nanometers, in order to allow light to interact with their entire thickness. This leads to numerous drawbacks including lower sensitivity and higher signal noise. Professor Lopez will work to develop a new generation of transparent superconducting films for SNSPD applications to overcome these…

The incredible power SpaceX’s Starship megarocket can be visualized in a new video of the rocket’s third test flight. On March 14, SpaceX’s massive Starship vehicle — the world’s largest and most powerful rocket — lifted off from the company’s manufacturing and test launch facilities near Boca Chica Beach at 9:25 a.m. EDT (1325 GMT). During the launch, shock waves propagate from the rocket in a stunning new slow motion video. Large clouds of smoke billowed out around the two-stage spacecraft, consisting of the reusable Starship cruise vessel mounted atop…
