NASA JPL (Jet Propulsion Laboratory) engineers tested next-generation Mars helicopter rotor blades, pushing them beyond the speed of sound to enable heavier payload capacity for future Red Planet aircraft missions.

Test engineers spun three-bladed rotors to 3,750 rpm inside JPL's 25-Foot Space Simulator, achieving rotor tip speeds at Mach 1.08 while withstanding simulated Martian headwinds across 137 separate test runs.

NASA's SkyFall mission, planned for December 2028 launch, will incorporate these findings to deliver three next-generation helicopters capable of carrying science instruments with 30% greater lift capability.

NASA's Psyche spacecraft will execute a Mars gravity assist on May 15, passing just 2,800 miles from the planet's surface while traveling toward the metal-rich asteroid Psyche in the main belt.

The spacecraft will approach Mars at 12,333 mph capturing thousands of images using its multispectral imager, following a 12-hour trajectory correction maneuver conducted February 23 using xenon-fueled solar-electric propulsion thrusters.

Principal investigator Lindy Elkins-Tanton from UC Berkeley notes the flyby provides critical instrument calibration opportunities before Psyche begins orbiting its asteroid target in late 2029.

University of Cincinnati graduate student Paul Smith led data analysis for JWST (James Webb Space Telescope) observations of exoplanet TOI-2031Ab, a solitary gas giant orbiting its star 901 light years from Earth.

The planet measures 25% larger than Jupiter with 20% less mass, completing its orbit in just six Earth days while Webb's near-infrared spectrographic sensors detected hydrogen, helium, water, and carbon dioxide in its atmosphere.

Cincinnati Observatory astronomer Wes Ryle states these gas giant migration studies help scientists evaluate how planetary systems form and identify potentially habitable worlds throughout the galaxy.

ESA released new JWST (James Webb Space Telescope) MIRI (Mid-Infrared Instrument) observations of Messier 77, a barred spiral galaxy located 45 million light-years away in the constellation Cetus featuring an exceptionally bright active core.

Webb's mid-infrared imaging reveals a supermassive black hole eight million solar masses powering the active galactic nucleus, surrounded by a starburst ring exceeding 6,000 light-years across with densely concentrated star-forming regions.

The observing programme surveyed massive nearby star-forming galaxies, creating datasets enabling scientists to explore stellar life cycles and gas reservoir dynamics across galactic structures with unprecedented resolution.

NASA's CHAPEA (Crew Health and Performance Exploration Analog) Mission 2 crew, commanded by Ross Elder, reached 200 days inside their sealed Mars simulation habitat at Johnson Space Center on May 7.

The four-person crew operates within a 1,700-square-foot 3D-printed habitat, currently experiencing a simulated two-week communications blackout mimicking Mars-Earth signal loss when Mars passes behind the Sun.

Project scientist Sara Whiting states this 378-day mission provides critical health and performance data informing NASA's development of sustainable lunar presence and longer-term crewed Mars mission planning.
