“In one of the first steps of the agency’s Artemis lunar exploration plans, NASA announced on Thursday the selection of Maxar Technologies, formerly SSL, in Westminster, Colorado, to develop and demonstrate power, propulsion and communications capabilities for NASA’s …

“NASA’s Mars Reconnaissance Orbiter hit a dizzying milestone this morning: It completed 60,000 loops around the Red Planet at 10:39 a.m. PDT (1:39 p.m. EDT). On average, MRO takes 112 minutes to circle Mars …

“Astronomers using NASA’s Hubble Space Telescope say they have crossed an important threshold in revealing a discrepancy between the two key techniques for measuring the universe’s expansion rate. The recent study strengthens the case that new theories may …

“On April 13, 2029, a speck of light will streak across the sky, getting brighter and faster. At one point it will travel more than the width of the full Moon within a minute and it will get as bright …

“NASA’s Mars InSight lander has measured and recorded for the first time ever a likely “marsquake.” The faint seismic signal, detected by the lander’s Seismic Experiment for Interior Structure (SEIS) instrument, was recorded on April 6, the lander …

“On April 10, 2019, the Event Horizon Telescope (EHT) unveiled the first-ever image of a black hole’s event horizon, the area beyond which light cannot escape the immense gravity of the black hole. That giant black hole, with a …

“Assembled from tiny identical pieces, the wing could enable lighter, more energy-efficient aircraft designs. A team of engineers has built and tested a radically new kind of airplane wing, assembled from hundreds of tiny identical pieces. The wing can change …

“New findings have emerged about five tiny moons nestled in and near Saturn’s rings. The closest-ever flybys by NASA’s Cassini spacecraft reveal that the surfaces of these unusual moons are covered with material from the planet’s rings …

“A NASA spacecraft that will return a sample of a near-Earth asteroid named Bennu to Earth in 2023 made the first-ever close-up observations of particle plumes erupting from an asteroid’s surface. Bennu also revealed itself to be more rugged …

“A NASA technologist is taking miniaturization to the extreme. Mahmooda Sultana won funding to advance a potentially revolutionary, nanomaterial-based detector platform. The technology is capable of sensing everything from minute concentrations of gases and vapor, atmospheric pressure and temperature, and …
