Japan’s ispace said its attempt to make the first private moon landing had failed after losing contact with its Hakuto-R Mission 1 (M1) lander when it unexpectedly accelerated and probably crashed on the lunar surface.

The startup said it was possible that as the lander approached the moon, its altitude measurement system had miscalculated the distance to the surface.

“It apparently went into a free-fall towards the surface as it was running out of fuel to fire up its thrusters,” Chief Technology Officer Ryo Ujiie told a news conference on Wednesday.

It was the second setback for commercial space development in a week after SpaceX‘s Starship rocket exploded spectacularly minutes after soaring off its launch pad.

A private firm has yet to succeed with a lunar landing. Only the United States, the former Soviet Union and China have soft-landed spacecraft on the moon, with attempts in recent years by India and a private Israeli company also ending in failure.

Ispace, which delivers payloads such as rovers to the moon and sells related data, had only just listed on the Tokyo Stock Exchange two weeks ago and a frenzy of excitement around its prospects had driven up its shares some seven-fold since then.

But disappointment led to a glut of sell orders on Wednesday. After being untraded all day, the stock finished down 20 percent in a forced closing price decided by the bourse that reflects the balance of buy and sell orders.

Japan’s top government spokesperson Hirokazu Matsuno said while it was sad that the mission did not succeed, the country wants ispace to “keep trying” as its efforts were significant to the development of a domestic space industry.

Japan, which has set itself a goal of sending Japanese astronauts to the moon by the late 2020s, has had some recent setbacks. The national space agency last month had to destroy its new medium-lift H3 rocket upon reaching space after its second-stage engine failed to ignite. Its solid-fuel Epsilon rocket also failed after launch in October.

Brakes on a high slope

Four months after launching from Cape Canaveral, Florida, on a SpaceX rocket, the M1 lander appeared set to autonomously touch down at about 1:40 am Japan time (1640 GMT Tuesday), with an animation based on live telemetry data showing it coming as close as 90 metres (295 feet) from the lunar surface.

By the expected touchdown time, mission control had lost contact with the lander and engineers appeared anxious over the live stream as they awaited signal confirmation of its fate which never came.

The lander completed eight out of 10 mission objectives in space that will provide valuable data for the next landing attempt in 2024, Chief Executive Takeshi Hakamada said.

Roughly an hour before planned touchdown, the 2.3 metre-tall M1 began its landing phase, gradually tightening its orbit around the moon from 100 km (62 miles) above the surface to roughly 25 km, travelling at nearly 6,000 km/hour (3,700 mph).

At such velocity, slowing the lander to the correct speed against the moon’s gravitational pull is like squeezing the brakes of a bicycle right at the edge of a ski-jumping slope, Ujiie has said.

The craft was aiming for a landing site at the edge of Mare Frigoris in the moon’s northern hemisphere where it would have deployed a two-wheeled, baseball-sized rover developed by the Japan Aerospace Exploration Agency, Tomy and Sony. It also planned to deploy a four-wheeled rover dubbed Rashid from the United Arab Emirates.

The lander was carrying an experimental solid-state battery made by Niterra among other devices to gauge their performance on the moon.

The mission was insured by Mitsui Sumitomo Insurance, an MS&AD Insurance Group unit, and ispace said it may receive some compensation.

2,300-Year-Old Dwarf Statuette from Alexandria Reveals Ptolemaic Art Insights

2,300-Year-Old Dwarf Statuette from Alexandria Reveals Ptolemaic Art Insights

A 2,300-year-old marble statuette discovered in Alexandria, Egypt, has offered new insights into how dwarves were perceived during the Ptolemaic period (332–150 B.C.). Depicting a muscular, nude dwarf in motion, the 4-inch sculpture reflects a combination of Egyptian and Greek artistic traditions. Despite missing its arms, legs, and part of the head, the craftsmanship of the piece indicates a highly skilled rendering of human anatomy. It is currently housed at the Metropolitan Museum of Art in New York City.

Depictions of Dwarves in Ptolemaic Art

According to information from the Metropolitan Museum of Art, as reported by Live Science, the statuette incorporates elements from Greek art, such as classical nudity and Hellenistic realism, blended with Egyptian cultural aesthetics. This synthesis points to the cultural exchange that characterised the Ptolemaic dynasty, a period when Egypt was ruled by Ptolemy I Soter, a general of Alexander the Great. The depiction of a dwarf engaged in dance suggests a significant societal role, unlike the exaggerated caricatures of dwarves often seen in Greek art.

Egyptian Perspectives on Dwarves

Historical records indicate that dwarves were highly regarded in ancient Egypt, often serving in the households of nobles and pharaohs. Their association with the god Bes, who was depicted as a short and muscular protector of families and women in childbirth, contributed to their societal acceptance. Bes, known as a dancer and tambourine player, symbolises strength and guardianship in Egyptian mythology. The statuette’s design, which likely depicted the dwarf with a percussion instrument, aligns with this cultural significance.

A Glimpse into Cultural Integration

The artifact demonstrates the integration of different human forms into Egyptian society during the Ptolemaic era. The Met has emphasised that such depictions reflect a broader tradition of valuing diverse body types, setting the Egyptian approach apart from other ancient civilisations. This statuette, though small in size, offers a profound understanding of cultural dynamics during a transformative period in history.

Lunar Temperature Fluctuations: Understanding the Moon’s Extreme Conditions

Lunar Temperature Fluctuations: Understanding the Moon's Extreme Conditions

The surface temperature of the moon experiences extreme variations, making it one of the harshest environments in the solar system. During lunar daylight, temperatures can soar to over 100 degrees Celsius, while in darkness, they can plummet to minus 100 degrees Celsius. These fluctuations are caused by the absence of an atmosphere, which on Earth moderates temperature extremes. Instead, the moon’s surface directly absorbs and radiates heat depending on exposure to sunlight.

Lunar Temperature Variations Explained

According to data provided by NASA and analysed by experts, such as John Monnier, a professor of astronomy at the University of Michigan, the moon’s soil, or regolith, significantly influences these temperature shifts. Regolith is a poor conductor of heat, causing rapid temperature changes on the surface while insulating the subsurface. As reported by Live Science, during Apollo missions, measurements indicated that temperatures beneath the surface were warmer by 40 to 45 kelvins compared to the lunar exterior.

Further research using NASA’s Lunar Reconnaissance Orbiter (LRO), launched in 2009, revealed localised thermal anomalies. Findings in 2022 demonstrated that shaded areas within certain lunar pits maintained a consistent temperature of 17 degrees Celsius. These regions are considered promising for future human habitation.

The Moon’s Poles and Extreme Conditions

The lunar poles present unique thermal environments due to the sun’s low angle. Permanently shadowed craters, particularly at the south pole, may host temperatures as low as minus 248.15 degrees Celsius. These craters are shielded not only from direct sunlight but also from secondary heat sources, such as reflected solar radiation. Such locations could hold trapped ice particles, potentially vital for sustaining future lunar exploration missions.

Understanding the moon’s thermal dynamics is essential for designing equipment capable of withstanding its conditions and planning potential settlements. Scientists and engineers continue to study these extremes to ensure that future missions can navigate and thrive in the lunar environment.
