Explanation: About 1,300 images from the Lunar Reconnaissance Orbiter spacecraft's wide angle camera were used to compose this spectacular view of a familiar face - the lunar nearside. But why is there a lunar nearside? The Moon rotates on its axis and orbits the Earth at the same rate, about once every 28 days. Tidally locked in this configuration, the synchronous rotation always keeps one side, the nearside, facing Earth. As a result, featured in remarkable detail in the full resolution mosaic, the smooth, dark, lunar maria (actually lava-flooded impact basins), and rugged highlands, are well-known to earthbound skygazers. To...

China pulls off a stunning space rescue, using a gravity slingshot to save its stranded moon satellites from certain destruction. A render of the navigation system. Image credit: CSU | The Daily Galaxy --Great Discoveries Channel In March 2024, China launched two satellites, DRO-A and DRO-B, as part of an ambitious mission aimed at positioning them in a distant retrograde orbit (DRO) around the moon. Their task was to provide critical navigation and tracking support for spacecraft within Earth-moon space. However, due to a malfunction with the Yuanzheng-1S upper stage of the launch vehicle, the satellites were stranded in an...

In a rare announcement that has captured the attention of scientists and the public alike, NASA has issued a warning about an asteroid with a 4% chance of striking the Moon in 2032. The news, which has stirred both intrigue and concern, highlights the ongoing efforts to monitor near-Earth objects (NEOs) and assess potential threats to our planet and its natural satellite. Astronomers tentatively designated the asteroid 2025-XF47. NASA’s Near-Earth Object Observations Program first detected it earlier this year. According to a statement from the agency, widely reported by outlets like CNN and BBC News, the object measures approximately 150...

Ground-based telescopes from the International Asteroid Warning Network have been tracking the asteroid, but it will be too faint to observe until June 2028...That’s why Webb was called in for the job, measuring the asteroid’s brightness across a range of infrared wavelengths to better determine its size. In late January, a team of scientists proposed using the mid-infrared instrument on Webb to observe the asteroid and better understand its damage potential. The team recently released the preliminary results of Webb’s observations of asteroid 2024 YR4, suggesting that, while the asteroid is larger and rockier than previous observations, it has nearly...

The second lunar lander made by Intuitive Machines has touched down on the Moon, but like the private aerospace company’s first spacecraft, it may not be upright. The Athena vehicle for Intuitive Machines IM-2 mission landed yesterday just 100 miles from the lunar south pole, but there’s uncertainty around its orientation which may impact the mission’s duration. “We don’t believe we’re in the correct attitude on the surface of the Moon yet again,” Intuitive Machines CEO Steve Altemus said during the post-landing news conference.“We’re going to get a picture from the lunar reconnaissance orbital camera from above and we’ll confirm...

This mission comes after the Cedar Park, Texas-based company Firefly Aerospace's Blue Ghost lunar...

Explanation: There's a new lander on the Moon. Yesterday Firefly Aerospace's Blue Ghost executed the first-ever successful commercial lunar landing. During its planned 60-day mission, Blue Ghost will deploy several NASA-commissioned scientific instruments, including PlanetVac which captures lunar dust after creating a small whirlwind of gas. Blue Ghost will also host the telescope LEXI that captures X-ray images of the Earth's magnetosphere. LEXI data should enable a better understanding of how Earth's magnetic field protects the Earth from the Sun's wind and flares. Pictured, the shadow of the Blue Ghost lander is visible on the cratered lunar surface, while the...

Blue Ghost just became the second private spacecraft ever to soft-land on the moon. Firefly Aerospace's Blue Ghost moon lander just etched its name into the history books. Blue Ghost aced its touchdown try early this morning (March 2), becoming just the second private spacecraft ever to soft-land on the moon. The lander hauled 10 science experiments to the lunar surface for NASA, which was understandably happy with today's result.

NASA’s Lunar Trailblazer approaches the Moon as it enters its science orbit in this artist’s concept. The small satellite will orbit about 60 miles (100 kilometers) above the lunar surface, producing the best-yet maps of water on the Moon. Credit: Lockheed Martin Space ============================================================================ NASA’s Lunar Trailblazer is gearing up for launch, riding on a SpaceX Falcon 9 as part of the IM-2 mission. This small yet powerful satellite will map water on the Moon, revealing its distribution, form, and movement. Before arriving at the Moon, the small satellite mission will use the gravity of the Sun, Earth, and Moon...

Explanation: Rima Hyginus is a spectacular fissure, some 220 kilometers long, found near the center of the lunar near side. Easy to spot in telescopic views of the Moon, it stretches top left to bottom right across this lunar closeup. The image was made with exaggerated colors that reflect the mineral composition of the lunar soil. Hyginus crater lies near the center of the narrow lunar surface groove. About 10 kilometers in diameter, the low-walled crater is a volcanic caldera, one of the larger non-impact craters on the lunar surface. Dotted with small pits formed by surface collapse, Hyginus rima...

The entirety of the lower 48 states, the greater Americas, and some regions beyond will witness — weather permitting — a total lunar eclipse the night of March 13 and into the early morning of March 14. This special cosmic event occurs when the moon, Earth, and sun are aligned. Long, red wavelengths of light pass through Earth's atmosphere and are projected onto the moon in majestic rusty or crimson colors. The coming total lunar eclipse, now less than a month away, is the first to grace Earth since 2022.

Several newly discovered structures on the far side of the moon were likely caused by relatively recent activity, challenging prior assumptions that the Earth’s only natural satellite stopped experiencing geological activity billions of years ago. Studies had previously concluded that the large arching ridges found on the moon’s near side were likely caused by heavy compression, most likely tectonic shifts that ended roughly three billion years ago. However, a new analysis by two Smithsonian Institution scientists and a University of Maryland (UMD) geologist focusing on the smaller ridges discovered on the far side of the moon has offered tantalizing hints...

... Orion's reentry followed a sharply angled trajectory, during which the capsule fell at an incredible speed before deploying three red and white parachutes. As the mission finished its trip of over 270,000 miles (435,000 kilometers), it looked to those on the deck of the USS Portland like the capsule had made it home in a single piece. As the recovery crew lifted Orion to the carrier's deck, shock waves ruffled across the capsule's surface. That's when crew members started to spot big cracks on Orion's lower surface, where the capsule's exterior bonds to its heat shield. But why wouldn't...

SpaceX successfully landed its Starship rocket in what Elon Musk calls one of the company's most important launches. SpaceFund founder Rick Tumlinson joins Josh Lipton on Asking for a Trend to talk about what the landing means for SpaceX and the space exploration industry. The venture capital fund focused on space exploration is invested in SpaceX. "What we're witnessing here [is the] combination of the railroads, the steamships, airplanes, all in one. Like 100 years from now, people are going to look back at this period of time as sort of when humanity breaks out into space, Tumlinson says, adding...

On July 24, 1969, Apollo 11 was 47,000 miles from Earth and rapidly accelerating toward its home planet when astronauts Neil A. Armstrong, Edwin E. “Buzz” Aldrin, and Michael Collins awoke for their last day in space, preparing for their splashdown in the Pacific Ocean 950 miles southwest of Hawaii. The previous day, managers were forced to move the splashdown point by 250 miles to the northeast due to inclement weather at the original recovery site. The aircraft carrier USS Hornet (CVS-12), the prime recovery ship for Apollo 11, was speeding for the new splashdown target area. Overcast skies made...

Explanation: No one, presently, sees the Moon rotate like this. That's because the Earth's moon is tidally locked to the Earth, showing us only one side. Given modern digital technology, however, combined with many detailed images returned by the Lunar Reconnaissance Orbiter (LRO), a high resolution virtual Moon rotation movie has been composed. The featured time-lapse video starts with the standard Earth view of the Moon. Quickly, though, Mare Orientale, a large crater with a dark center that is difficult to see from the Earth, rotates into view just below the equator. From an entire lunar month condensed into 24...
