Caroline Smith, who works at the Natural History Museum, discusses a new discovery made by a NASA rover that may provide evidence of past life on Mars.

SpaceX will once again try to get a fresh haul of supplies to the International Space Station this weekend after bad weather at the launch site forced the company to wave off its first attempt.

The first mission in NASA’s Artemis program finally took the Orion spacecraft on a trip around the moon, a huge step forward for the ambitious plan to bring humans to the lunar surface as soon as 2025. It’s also the beginning of the White House’s far-reaching ambitions for a permanent outpost on the moon.

NASA has released new close-up images of the far side of the moon, taken from the uncrewed Orion spacecraft.

NASA's successful Moon rocket launch last week will be a boon for private companies, experts tell Axios. Why it matters: As global economic growth slows, space and Moon exploration could become a source of ignition for new ventures and jobs.

NASA signed an arrangement with the Japanese government that extends Japan’s presence on the International Space Station (ISS) until 2030, in addition to contributing components for a future lunar outpost.

By 2050, sea level along contiguous U.S. coastlines could rise as much as 12 inches (30 centimeters) above today’s waterline, according to researchers who analyzed nearly three decades of satellite observations. The results from the NASA Sea Level Change Team could help refine near-term projections for coastal communities that are bracing for increases in both catastrophic and nuisance flooding in coming years.

NASA launched the most powerful rocket ever built on a journey to the Moon on Wednesday, in a spectacular blaze of light and sound that marked the start of the space agency's new flagship program, Artemis.

Fifty years ago this month, mission managers at the US space agency Nasa gave the final go-ahead for what would turn out to be humanity’s most recent odyssey to the moon. Few realized at the time it would be more than half a century before Nasa would be ready to return, not least Apollo 17 commander Eugene Cernan, whose belief as he stepped back into the lunar module in December 1972 was that it would be “not too long into the future” that astronauts were there again.

A secretive Space Force spaceplane streaked across Florida early Saturday, generating unmistakable sonic booms en route to a landing at Kennedy Space Center that wrapped up another record-breaking mission.

On New Year’s Day three years ago, a small spacecraft zoomed by a chunk of ice billions of miles away, and scientists on Earth cheered. That was the second time the New Horizons probe got up close and personal with an object in the far-away Kuiper Belt—after capturing images of Pluto, its first target, in unprecedented detail.

The contracting for the next moon buggy for Artemis has begun.

As subtropical storm Nicole moved across the Atlantic Ocean toward Florida on Monday afternoon, NASA confirmed that its Artemis I mission would remain at the launch pad along the state's east coast. "Based on current forecast data, managers have determined the Space Launch System rocket and Orion will remain at Launch Pad 39B," the agency said.

NASA scientists have developed a new device designed to autonomously detect life in the watery plumes shooting into space from icy moons like Enceladus and perhaps Europa.

The Sun is finally in a good mood. A jolly photograph released by NASA shows the Sun "smiling for the camera". In an image taken from NASA’s Solar Dynamics Observatory (SDO), a face-like pattern appeared on the surface of the nearest star to the Earth. As per the space agency, the friendly expression on the surface of the sun was formed due to black patches known as coronal holes.

When it comes to dramatic and awe-inspiring pictures of space, few can contend with what appears to be a pic of, well, nothing at all: a fascinating image of what seems to be a hole in the fabric of space, taken by the NASA/ESA Hubble Space Telescope.

Last June, NASA announced that it would convene a panel to study "unidentified aerial phenomena" (UAP), aka UFOs — while saying it doesn't believe they're "extraterrestrial in origin." Now, the space agency has unveiled the 16-member panel that will focus on "unclassified sightings and other data collected from civilian government and commercial sectors."

The International Space Station had to fire its thrusters this week to make sure it avoided space junk in orbit around Earth. The station fired its thrusters for 5 minutes and 5 seconds in what NASA called a "Pre-Determined Debris Avoidance Maneuver" at 8:25 p.m. ET Monday to increase its distance from a piece of what used to be a Russian satellite.

The famous clouds of gas and dust are dazzling in the state-of-the-art instrument’s eye.

Former NASA astronaut James A. McDivitt, who commanded the Apollo 9 mission, died on Thursday in Tucson, Arizona, surrounded by his family and friends, NASA said in a statement. He was 93. McDivitt spent 14 days in space over the course of his career. He was selected to be a member of NASA's second astronaut class in September 1962 after graduating from the Air Force Experimental Test Pilot School and serving as an experimental test pilot at Edwards Air Force Base, California.
