NASA and SpaceX have agreed to study the feasibility of awarding Elon Musk’s company a contract to boost the Hubble Space Telescope to a higher orbit, with a goal of extending its lifespan, the US space agency said Thursday.

The renowned observatory has been operating since 1990 about 335 miles (540 kilometers) above Earth, in an orbit that slowly decays over time.

Hubble has no on-board propulsion to counter the small but still present atmospheric drag in this region of space, and its altitude has previously been restored during Space Shuttle missions.

The proposed new effort would involve a SpaceX Dragon capsule.

“A few months ago, SpaceX approached NASA with the idea for a study whether a commercial crew could help reboost our Hubble spacecraft,” NASA’s chief scientist Thomas Zurbuchen told reporters, adding the agency had agreed to the study at no cost to itself.

He stressed there are no concrete plans at present to conduct or fund such a mission until the technical challenges are better understood.

One of the main obstacles would be that the Dragon spacecraft, unlike the Space Shuttles, does not have a robotic arm and would need modifications for such a mission.

SpaceX proposed the idea in partnership with the Polaris programme, a private human spaceflight venture led by payments billionaire Jared Isaacman, who last year chartered a SpaceX Crew Dragon to orbit the Earth with three other private astronauts.

“This would certainly fit within the parameters we established for the Polaris programme,” Isaacman said in response to a question about whether reboosting Hubble could be the goal for a future Polaris mission.

Asked by a reporter whether there might be a perception that the mission was contrived in order to give wealthy people tasks to do in space, Zurbuchen said: “I think it’s only appropriate for us to look at this because of the tremendous value this research asset has for us.”

Arguably among the most valuable instruments in scientific history, Hubble continues to make important discoveries, including this year detecting the farthest individual star ever seen — Earendel, whose light took 12.9 billion years to reach us.

It is currently forecast to remain operational throughout this decade, with a 50 percent chance of de-orbiting in 2037, said Patrick Crouse, Hubble Space Telescope project manager.

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.
