Indian Space Research Organisation (ISRO) Chairman S Somnath on Monday said that the Chandrayaan-3- the third edition of India’s mission to the moon- will be launched this July.

Chandrayaan-3 is a follow-on mission to Chandrayaan-2 to demonstrate end-to-end capability in safe landing and roving on the lunar surface.

“I am very confident…” said Somnath today on the lunar mission.

The ISRO chairman was speaking after the space agency successfully placed the NVS-01, the first of the second-generation satellite series, into geosynchronous transfer orbit. The Geosynchronous Satellite Launch Vehicle deployed the NVS-01 navigation satellite from the second launch pad at the Satish Dhawan Space Centre (SDC SHAR) in Sriharikota in Andhra Pradesh.

Speaking to ANI, Somanath said, “The lesson is very simple. Learn from the past, and do what is possible with your capacity. Failures may happen. There are a thousand reasons for a rocket to fail. Even today, this mission could have failed. But we have to do what is needed to be done”.

Meanwhile, the Chandraayan-3 mission consists of an indigenous lander module a propulsion module and a rover with an objective of developing and demonstrating new technologies required for Inter planetary missions.

According to ISRO, the three mission objectives of the Chandrayaan-3 are- to demonstrate safe and soft landing on lunar Surface; to demonstrate Rover roving on the moon and to conduct in-situ scientific experiments.

It will be launched by the LVM3 rocket from SDSC SHAR centre in Sriharikota. The propulsion module will carry the lander and rover configuration till 100 km lunar orbit, according to ISRO.

The propulsion module has Spectro-polarimetry of Habitable Planet Earth (SHAPE) payload to study the spectral and Polari metric measurements of Earth from the lunar orbit.

The Lander will have the capability to soft land at a specified lunar site and deploy the Rover which will carry out in-situ chemical analysis of the lunar surface during the course of its mobility. The Lander and the Rover have scientific payloads to carry out experiments on the lunar surface.

The main function of the Propulsion Module is to carry the Lander Module from launch vehicle injection till final lunar 100 km circular polar orbit and separate the Lander Module from the Propulsion Module.

Apart from this, the Propulsion Module also has one scientific payload as a value addition which will be operated post separation of Lander Module.

The launcher identified for Chandrayaan-3 is GSLV-Mk3 which will place the integrated module in an Elliptic Parking Orbit (EPO) of size 170 x 36500 km.

The Chandrayaan is an ongoing series of lunar space exploration programme of the ISRO. Chandrayaan-1, the first lunar probe of ISRO, in 2008-09 found water on the moon. The Chandrayaan-2 was launched in July 2019 and successfully inserted into orbit in August 2019. However, minutes its lander crash-landed on the moon after losing communication with the ground stations.

Earlier in the day, the ISRO Chairman Somnath congratulated the whole ISRO team after the successful launch of NVS-01.

“I would like to congratulate everyone on the outcome. The satellite is placed in the precised orbit. Congratulates to the entire ISRO for making this mission happen,” ISRO Chairman Somnath said in a press conference.

He appreciated the fact that the mission was accomplished after doing the rectifications after suffering a debacle during the last mission.

“This mission GV-F12 came after the debacle that happened in the F-10 mission where there was an issue in the cryogenic stage and the cryogenic engine could not get accomplished. I am very happy that the correction and modification at the cryogenic stage were done and we learnt the lessons to make our cryogenic stage more reliable. I want to specifically congratulate the entire ‘Failure Analysis Committee’ who went through this and made our life much better and also for the Liquid Propulsion System,” he said.

Somnath added, “Today the Navigation Satellite NVS-01 is the second generation of navigation satellite with additional capabilities that we have already brought into the satellite constellation where we make the signals more secure. We made a civilian frequency band L-1 and also introduced our Atomic Clock. And this is one of the five series of satellites with new configurations that are to be launched. I would like to thank all those who worked for this satellite and make the mission a grand success”.

Appreciating the government support, the ISRO Chairman also thanked the authorisation of the GSLV launch despite a failure during the last attempt.

“The confidence of the decision makers, our honourable Prime Minister Narendra Modi and other key functionaries who reviewed it to see that we have done the required work. The Navic Constellation is something very crucial for the nation to have a regional navigation constellation. I take this opportunity to tell you that we are going to make this Navic system fully functional and operational for the benefit of this nation,” he said.

He further said that the satellite is currently in Geosynchronous Transfer Orbit, from where it is the responsibility of the satellite team to correctly place it in the orbit.

Apprising about the future missions of ISRO, Chairman Somnath said, “In the coming months, we are going to launch PSLV as well as GSLV Mark-3. We are also going to launch the test vehicle of the Gaganyan (Man mission). Of course, the launches of further PSLV and SSLV are also in line”

“We are having the next launch of GSLV with a Climate and weather observation satellite called INSAT-3DS, which will be happening soon. And after that, the same rocket is bound to take NISR – India Nasa Synthetic Alergic Radar Satellite as well,” he added.

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

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.
