The second Mercury mission was going according to plan until the Liberty Bell 7 capsule sank in the ocean. NASA exonerated astronaut Gus Grissom, and two researchers now say they know what happened.

The Perseids meteor shower has been called "The best meteor shower of the year." It peaks in mid-August.

Researchers say high tide flooding in U.S. coastal regions will become more frequent in the mid-2030s because of climate change, amplified by a routine wobble in the moon's orbit.

Its name has ties to strawberry picking season, and when the strawberry moon appears above the horizon, the marginal supermoon will look large and gold.

"It's just the inefficiency of trying to fix something which is orbiting 400 miles over your head instead of in your laboratory," said Paul Hertz, the director of astrophysics for NASA.

Early risers across the Northern Hemisphere will be able to see an eclipse Thursday morning when the moon passes between the Earth and the sun.

NASA's Juno spacecraft traveled to 645 miles above the surface of the solar system's largest moon, Ganymede, on Monday.

The animals are being launched into the cosmos as NASA researchers attempt to learn more about how the conditions of spaceflight can affect biological organisms and, by extension, future astronauts.

The two space probes will study Venus, a scorching hot world that may have once been like Earth. NASA chose the Venus missions over other candidates, such as trips to the moons of Jupiter and Neptune.

NASA announced Friday that it would be increasing operational testing on its Ingenuity helicopter following four successful test flights off the surface of Mars.

Climate and health policies rely on scientific expertise. But the federal science workforce has been shaped by decades of political interference, underfunding and race and gender bias.

Four astronauts are set to launch to the space station Friday. When they arrive, the new crew of 11 will be the largest since the shuttle program, and there aren't enough sleeping pods for them all.

The tiny helicopter took off and hovered briefly — the first such flight on another planet. The Perseverance rover kept tabs on the mission from a viewing point about 60 yards away.

Jet Propulsion Laboratory project manager MiMi Aung gave an enthusiastic two thumbs-up and then clenched fists before a roomful of engineers erupted in applause.

The successful deployment of Ingenuity brings NASA one step closer to its first attempt at testing the possibility of powered, controlled flight on another planet.
