In less than a week, the second privately constructed US spacecraft is poised to land on the moon.

The robot lander, named Athena, was created by an intuitive machine based in Texas. It was launched into space on February 26th and has been traveling to the moon for the past week.

About the size of a dishwasher, the six-legged ship is set to land in the lunar Antarctic area, with plans to spend a week searching for possible water ice beneath the lunar surface.

The landing is scheduled for Thursday at 12:32 pm ET.

If successful, Athena will be the second vehicle to land on the moon in five days, following another robotic lander built by Texas-based Firefly Aerospace, which landed there on Sunday.

Both missions are part of NASA’s Commercial Moon Payload Services program, aimed at assisting private companies in developing Moonlander technology. Over a dozen US companies are involved in this initiative, which is crucial to NASA’s overarching goal of returning astronauts to the moon.

Athena’s landing will mark the second moonshot for the intuitive machine. The company previously made history in February 2024 by landing a commercially built spacecraft on the moon, becoming the first American spacecraft to land there in over 50 years since the 1972 Apollo 17 mission.

The Lander, known as Odysseus, experienced a successful landing despite tipping over afterwards.

Both intuitive machine missions are focused on the Antarctic region of the moon. Odysseus landed near a crater called Marapart A, while Athena is targeting a vast flat mountain plateau known as Mons Mouton.

Scientists believe that water ice is relatively abundant in the moon’s Antarctic region, making it a crucial resource for potential crew missions and long-term stays on the moon.

Athena is equipped with several rovers, including the suitcase-sized vehicles developed by Colorado-based Lunar Outpost called Mapp (Mobile Autonomous Research Exploration Platform). These rovers are designed to explore the landing site and capture 3D images of the terrain.

Furthermore, a thumb-sized rover named “Astroant,” created by researchers at the Massachusetts Institute of Technology, will assess the health of the map rover and take regular temperature measurements.

In addition, the mission includes releasing a drone named Grace, which will hop around the Athena landing site, covering approximately 650 feet in four hops to explore nearby craters and scan for hydrogen traces and ice deposits.

While on the moon, Athena will also test a 4G communications system developed by Nokia, which could facilitate communication and data transfer between spacecraft on the moon.

Moon exploration continues beyond this week, with a Lander and small rover from a Japanese company called Ispace set to land near the northern pole’s vast basin known as Male Frigolis.

These images illustrate the pockmarked surface of Mercury and are a preview of what to expect as the BepiColombo mission enters orbit around the innermost region of our solar system in late 2026.

Since its launch in 2018, the joint Japan-Europe spacecraft BepiColombo has made six flybys of Mercury, gradually decelerating with each pass to fine-tune its trajectory for orbital insertion. While the mission’s primary scientific instruments are yet to be utilized, the spacecraft’s cameras have already provided detailed images of the planet.

The European Space Agency (ESA) recently released three striking images captured during BepiColombo’s latest flyby on January 8, taken from an altitude of around 300 kilometers above Mercury’s north pole and northern regions.

David Rothery, from the Open University, UK, shared his excitement about the images, saying, “We had to wake up early to see these close-ups, and they exceeded our expectations based on simulated views we studied beforehand.”

The image above showcasing Mercury’s north pole reveals the sharp contrast between light and darkness on the planet, known as the terminator line. This region shows extreme temperature variations, with some areas exposed to scorching sunlight while others remain perpetually shaded within craters.

Notably, shadowed regions containing potential frozen water deposits can be observed along the terminator line in the image. Rothery further highlights the fascinating details visible, such as the sunlit peak inside Tolkien Crater, providing key insights for the mission’s scientific objectives.

Scientific investigations suggest that these shadowed crater areas may harbor frozen water, a key aspect of BepiColombo’s mission to uncover the presence and extent of water on Mercury.

Mesmerizing images from BepiColombo’s mission highlight Mercury’s expansive volcanic plain known as Borealis Planitia, formed over 3 billion years ago from massive lava flows that engulfed existing craters, some of which are visible in the image. While most of these plains are relatively smooth, more recent impact craters provide intriguing targets for scientific study.

Spanning 1,500 kilometers, the Caloris Basin is the largest crater on Mercury, appearing as a semicircular light-colored feature on the planet’s surface. Once BepiColombo enters orbit, researchers aim to investigate the relationships between the Caloris Basin, Borealis Planitia, and the solidified lava flows connecting them.

The illuminated region at the top of the planet, known as Natal Facula, is believed to be the aftermath of Mercury’s most significant volcanic eruption. The presence of a central crater, approximately 40 kilometers wide, indicates multiple eruptions that scattered volcanic material over hundreds of kilometers.

Rothery expresses eagerness for future observations of Natal Facula by BepiColombo’s instruments, emphasizing its scientific importance in understanding Mercury’s volcanic history. Discovering the reasons behind Mercury’s enduring volcanic activity remains a key goal of the mission.

London’s Medieval Horses Originated from Faraway Lands

International trade may have helped medieval elites obtain the best horses for jousting tournaments

Analysis of horse teeth unearthed in a London cemetery suggests that the horses owned by medieval England's elite were likely imported from continental Europe and may have traveled hundreds of kilometers.

In the 1990s, a commercial excavator accidentally discovered an unusually large horse burial ground in central London. Subsequent excavations at the site, now known as Elberton Street Cemetery, uncovered the full or partial remains of 70 horses. Some graves date him from 1425 to 1517, but the cemetery may have been in use over a wider period.

“This is a great example of the only true horse cemetery in medieval England,” he says. Oliver Clayton at the University of Exeter, UK. “We usually [horse remains] Very few are scattered on archaeological sites. ”

To learn more about the origins and lives of these medieval horses, Creighton and his colleagues collected and analyzed molars from 15 horses buried at the site.

Plants from different parts of the world contain different levels of carbon, oxygen, and strontium isotopes, or atoms with different numbers of neutrons. When animals eat these plants, these isotopes accumulate in their bones and teeth over time. By analyzing the chemical signature of the horse's teeth, the researchers were able to determine where it likely came from.

It said this revealed that at least seven people came from abroad, possibly from Scandinavia or the Western Alps. alexander pryoralso at the University of Exeter.

“These were also the largest medieval horses ever discovered in Britain,” Pryor said, noting that Britain's elite may have sought out the best horses from Europe. Suggests.

The arrangement of their teeth seemed to suggest the use of special mouthpieces normally reserved for horses groomed for combat and jousting tournaments.

“The horse likely came from the equestrian arena at the Palace of Westminster, just a kilometer away,” Clayton said.

“The nature of horse teeth, with their very tall crowns growing over many years, offers great potential for research using isotopes to track the movements of individual horses over their lifetime,” he said. To tell. david orton At York University, UK. “But this is the first paper I've seen that seems to take full advantage of that potential.”

Japan's Smart Lander for Lunar Exploration (SLIM) has landed on the moon. Although the spacecraft is not operating perfectly, the successful landing follows a series of recent failed moon landings by governments and private spaceflight companies, and remains encouraging for international efforts to explore the moon. . With this landing, Japan will become the fifth country to land on the moon, following the United States, Soviet Union, China, and India.

The Japan Aerospace Exploration Agency (JAXA) launched SLIM in September 2023, and the spacecraft took a long orbit to the moon, circling the Earth several times to conserve fuel. It has been orbiting the moon since December, taking images of the surface and preparing for landing.

The January 19 touchdown marked the first use of a technology engineers dubbed “smart eye,” which allows SLIM to aim its landing spot with extreme precision. SLIM determined its position by comparing images from its onboard camera with data from other spacecraft orbiting the moon, then autonomously navigated to a landing site on the slopes of Sioli Crater. JAXA officials are continuing to analyze how well the targeting protocol worked.

Initial signals from SLIM suggest that the solar panels do not appear to be operational, so the spacecraft is operating on battery power for now. If spacecraft operators are unable to figure out what's wrong with the solar cells and get them working, SLIM's scientific capabilities could be hampered and its lifespan significantly shortened. According to JAXA officials, battery life is expected to be only a few hours. It's possible the spacecraft will regain solar power, but for now JAXA's priority is to return as much data as possible to Earth before its batteries run out.

As SLIM descended to the lunar surface, two small rovers, each carrying a small payload of scientific instruments, also descended. One of them is designed to bounce rather than roll on wheels, and the other is a tennis ball. He was designed by toy manufacturers to roll on the moon, with a sphere slightly smaller than a ball. The spacecraft appears to be functioning normally.

Spacecraft landing sites are potentially important. Previous observations suggest that material may have come from inside the moon during the impact that formed the crater. SLIM's scientific instruments can study these minerals to learn about the formation and evolution of the Moon. A successful landing and the scientific data collected will provide useful data for the many spacecraft scheduled to travel to the moon from around the world in the coming years.
