Chandrayaan-3, India’s third lunar exploration mission, will make India the fourth country to land its spacecraft on the surface of the moon and demonstrate the country’s abilities for safe and soft landing on lunar surface.

The countdown for the launch of mission will begin on Thursday ahead of take off on Friday from the Satish Dhawan Space Centre in Sriharikota.

“Mission Readiness Review is completed. The board has authorised the launch. The countdown begins tomorrow,” ISRO said in a tweet.

It will be launched on a GSLV Mark 3 (LVM 3) heavy lift launch vehicle.

This will be Indian Space Research Organisation’s (ISRO) follow-up attempt after Chandrayaan-2 mission faced challenges during its soft landing in 2019.

The ‘Launch Rehearsal’ simulating the entire launch preparation and process has been concluded by the ISRO.

If all goes well, Chandrayaan-3 will be the first spacecraft to land on Moon’s South Pole, demonstrating India’s technical prowess and bold spacefaring ambitions.

Chandrayaan-3 mission will demonstrate safe and soft landing on lunar surface, rover roving on the moon and conduct in-situ scientific experiments.

ISRO invited citizens to witness the launch of the much-awaited Chandrayaan-3 from the viewing gallery at Sriharikota.

During Chandrayaan-2 mission, ISRO lost contact with the lander when it was just a notch away from the moon’s surface.

The journey from earth to the moon for the to-be-launched spacecraft is estimated to take around a month and the landing is expected on August 23. Upon landing, it will operate for one lunar day, which is approximately 14 earth days. One day on Moon is equal to 14 days on earth.

K Sivan, former director of ISRO, told ANI that success of mission Chandrayan-3 will give a morale boost to programs like Gaganyan.

“We understood what went wrong with Chandrayan-2 when we could not land on the moon surface, we recreated the failure modes and we ensured that this time we have success. The challenge is the same as Chandrayan-2, same environment for landing. This time we hope that we have done enough based on the lesson of Chandrayan-2 that gives us more confidence. In space there are always unknown unknowns…hope that all issues are addressed and that we emerge with success,” he said.

“We are getting tech landing on a celestial body. By landing successfully, we will acquire landing technology and it will be good for future generations. A number of scientific experiments are planned and scientists will have more knowledge of moon’s geology and earth’s origin,” he added.

Mylswamy Annadurai, Mission Director of Chandrayaan-1, said Chandrayaan-3 is a very important mission.

“We have shown that we can orbit, but we could not do a soft landing, By doing so this time we can show that Chandrayan-1 was not an isolated success. Internationally, the world is looking back to the moon, the real seeding for that came from Chandrayaan-1. So we need to make this mission successful,” he told ANI.

“Hard lessons were learnt from Chandrayaan 1 and 2. At every step, we are supposed to have a plan B. There were some setbacks in Chandrayaan- 2. This time we are back on track. We are clear on what we want to do and it will ensure we can softly land on the surface of the moon. Target of landing is also larger, all elements have been tested multiple times, we hope this is a success…,” he added.

Chandrayaan-3’s development phase commenced in January 2020 with plans to launch it somewhere in 2021, but the COVID-19 pandemic caused delays in the development process.

The major discovery of the Chandrayaan-1 mission, launched in 2008, is the detection of water (H2O) and hydroxyl (OH) on the lunar surface. Data also revealed their enhanced abundance towards the polar region.

“The primary science objective of the mission was to prepare a three dimensional atlas of both near and far side of the Moon and to conduct chemical and mineralogical mapping of the entire lunar surface with high spatial resolution,” Vikram Sarabhai Space Centre under ISRO had said.

Moon serves as a repository of earth’s past and a successful lunar mission by India will help in enhancing life on Earth and prepare to explore the rest of the solar system — and beyond.

Director of Indian Space and Research Organisation (ISRO), S Somanath, had said that if everything goes well, the spacecraft will land on the moon on August 23.

The date has been decided based on sunrise on the moon but if it gets delayed, then landing may take place next month, he said.

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.
