A private lunar lander, Blue Ghost, captured the first high-definition sunset photos on the Moon. The lander ceased operations after collecting data during the lunar night. Scientists will analyze images to study the horizon glow. Reactivation efforts are planned, but success is uncertain.

Understanding the causes and alerts associated with tornadoes is critical for safety. Tornadoes, spawned by low-pressure systems and specific atmospheric conditions, can cause widespread damage. Awareness and preparedness, including heeding watches and warnings, are key to minimizing risk. Secure shelters and weather radios are essential tools.

EPA Administrator announces nearly three dozen deregulatory moves, impacting rules for clean air, water, and emissions. These changes aim to spur the U.S. economy by easing burdens on industry, but critics worry about potential environmental and health consequences. Key regulations on power plants, wastewater, and chemical safety are under review.

SpaceX delayed a flight to the ISS due to a launch pad issue, affecting the return of two NASA astronauts. A hydraulic system problem arose before the Falcon rocket's planned liftoff. The new launch date is uncertain, pending further assessment by SpaceX. The mission aims to replace astronauts stuck due to Boeing's Starliner capsule issues.
