Russia’s Luna-25 mission
GS Paper - 3 (Space Technology)
As the Chandrayaan-3 mission tightens its orbit around the Moon, Russia was launched its first moon-landing spacecraft in 47 years on 11 August 2023. The Luna-25 mission is scheduled to land on the Moon on 23 August 2023, the same day as Chandrayaan-3’s planned landing.
More about Luna-25
Luna-25 was launched from the Vosthochny cosmodrome in the Russian Far East less than a month after Chandrayaan-3 launched from the Satish Dhawan Space Center in Sriharikota.
The Russian mission will try to land on the lunar South Pole just like the Indian mission, aiming for a prized destination that may hold significant quantities of ice that could be used to extract oxygen and fuel in the future.
If either of the missions succeeds before the other, it will be the first one to land on the lunar South Pole in human history.
Roscosmos, Russia’s ISRO counterparts said that Luna-25 will practice soft-landing, analyse soil samples and conduct long-term scientific research on the Moon’s surface.
The Chandrayaan-3 mission is carrying an orbiter, a lander and a rover. The lander and rover are carrying many scientific payloads.
This is Russia’s first lunar mission since 1976 when the country was part of the Soviet Union and it will be completed without equipment from the European Space Agency (ESA). ESA ended its cooperation with Roscosmos after Russia invaded Ukraine.
Luna-25 has a mass of 1.8 tons and carries 31 kilograms of scientific equipment, including some that it will use to take rock samples from up to a depth of 15 centimetres to test for the presence of water that could be used to support future crewed missions to the Moon.
The mission was originally scheduled to launch in October 2021 but was marred by many delays.
The Russian mission will take a lot less time to reach the Moon than Chandrayaan-3 because the latter is taking a longer route that takes advantage of the gravities of the Earth and the Moon to use a lot less fuel.
Russia willevacuate villagers from a village near the launch site due to a “one in a million chance” that one of the rocket stages that launches could fall to the Earth there.

Russia’s Luna-25 crashes
GS Paper - 3 (Space Technology)
Russia’s Moon mission ended in failure after its spacecraft Luna-25 spun out of control and crashed into the moon, Russian space agency Roscosmos said on 20 August 2023.
What happened to Luna-25?
Luna-25 was supposed to land on the Moon on 21 August 2023, days ahead of India’s Chandrayaan-3. Its intended landing site was close to Chandrayaan-3’s, near the lunar south pole.
The crash was confirmed a day after Roscosmos reported an “abnormal situation” which its specialists were analysing.
The space agency had said on 19 August 2023 that it had lost contact with the aircraft as it was shunted into pre-landing orbit.
On 19 August 2023, in accordance with the flight program of the Luna-25 spacecraft, an impulse was provided for the formation of its pre-landing elliptical orbit.
Communication with the Luna-25 spacecraft was interrupted. The measures taken on 19 and 20 August 2023 to search for the device and get into contact with it did not produce any results. According to the results of the preliminary analysis, due to the deviation of the actual parameters of the impulse from the calculated ones, the device switched to an off-design orbit and ceased to exist as a result of a collision with the lunar surface, Roscosmos said.
The space agency also said, A specially formed interdepartmental commission will deal with the issues of clarifying the reasons for the loss of the Moon [mission].
What was the Luna-25 mission?
Although launched on 10 August 2023, almost a month after Chandrayaan-3’s launch on 14 July, Luna-25 rode on a powerful rocket to reach the lunar orbit in just six days.
It was supposed to land on the lunar South Pole before Chandrayaan-3, and its success would have made Russia the first country to do so. Luna-25’s mission life was for one year, and its lift-off mass was 1,750 kg.
It did not carry a rover, but had eight payloads mainly to study the soil composition, dust particles in the polar exosphere, and most importantly detect surface water on the moon.
Significance
The failure of Luna-25 underlines how tricky soft-landings on the Moon are, and echoes India’s heartbreak of 2019.
Since 1976, there has been just one country, China, which has been successful in getting its spacecraft to soft land on the moon.
It has done that twice, with Chang’e 3 and Chang’e 4. All other attempts in the last ten years, by India, Israel, Japan and now Russia, have remained unsuccessful.
If Chandrayaan-3 is able to land successfully, India would become just the fourth country in the world, after the United States, the erstwhile Soviet Union and China, to have landed a spacecraft on moon, and the first-ever to land close to the lunar south pole.

Vikram lander creates history
GS Paper - 3 (Space Technology)
India became the first country to touch down on the lunar South Pole on 23 August 2023 as billions watched from around the globe. The Chandrayaan-3 lander - designed to deploy a smaller, 26-kg lunar rover - landed on the surface of the moon, marking a giant leap in India’s spacefaring journey.The Moon has captivated human curiosity for centuries, and with each new mission.
What is the Moon's geological history and evolution?
The Moon is estimated to be about 4.5 billion years old, roughly the same age as the Earth.
The leading theory about the Moon's formation suggests that a Mars-sized celestial body collided with the young Earth, and the debris from this collision eventually coalesced to form the lunar body.
However, current geological evidence from the Moon suggests that it may be younger by just 60 million years compared to Earth.
How much do things weigh on the Moon?
The Moon's gravitational pull is much weaker than Earth's, approximately one-sixth of Earth's gravity.
As a result, objects on the Moon weigh significantly less than they do on Earth. This is due to the Moon's smaller size and mass.
For example, a person weighing 68 kilograms on the Earth would weigh only over 11 kg on the Moon.
Why do Indian scientists want to land on the Moon's South Pole?
The lunar South Pole has become a focal point for exploration due to its unique features and potential scientific value.
It is believed to host a vast reservoir of water ice in permanently shadowed regions. The presence of water is of immense significance for future space exploration, as it can be converted into resources such as drinking water, oxygen and hydrogen for rocket fuel.
Also, the permanently sunlit area in the region has a temperature of around minus 50 to 10 degrees Celsius, which provides better chemical conditions for the electronics onboard the rover and lander to work properly.
What is in the lunar South Pole?
The terrain and geology at the Moon's South Pole are distinct from other regions. Permanently shadowed craters provide extremely cold conditions that allow water ice to accumulate and persist.
The unique geography of the South Pole also creates regions of perpetual sunlight, which can be harnessed for solar power.
The terrain varies from rugged landscapes to relatively flat plains, offering a diverse range of scientific opportunities.
Why is a region of the lunar South Pole permanently shadowed?
This depends on the Moon's geology. The Moon's axis is only slightly tilted relative to its orbit around the Earth.
This results in certain areas near the poles being in permanent shadow. These shadows create extremely cold environments where temperatures can plummet to very low levels.
These frigid conditions are conducive to preserving water ice for billions of years.

Experiments after Chandrayaan-3’s landing
GS Paper - 3 (Space Technology)
After rolling down a ramp from the Chandrayaan-3 lander, the six-wheel, 26-kg rover, which is capable of slowly moving up to 500 metres, began its job of lunar exploration. The landing happened at lunar dawn, and the six payloads on board the lander and rover was started collecting data soon after to get as much science as possible in the single lunar day or 14 Earth days for which they will remain operable.
Mission experiments
The lander has four experiments on board.
The Radio Anatomy of Moon Bound Hypersensitive ionosphere and Atmosphere (RAMBHA) will study the electrons and ions near the surface of the moon and how they change over time.
The Chandra’s Surface Thermo physical Experiment (ChaSTE) will study the thermal properties of the lunar surface near the polar region. Chandrayaan-3 has landed around 70 degree south latitude, the closest that any spacecraft has reached to the lunar South Pole.
The Instrument for Lunar Seismic Activity (ILSA) will measure the lunar quakes near the landing site and study the composition of the Moon’s crust and mantle.
The LASER Retroreflector Array (LRA) is a passive experiment sent by NASA that acts as a target for lasers for very accurate measurements for future missions.
There are two scientific experiments on the rover
The LASER Induced Breakdown Spectroscope (LIBS) will determine the chemical and mineral composition of the lunar surface.
The Alpha Particle X-ray Spectrometer (APXS) will determine the composition of elements such as magnesium, aluminium, silicon, potassium, calcium, titanium, and iron in the lunar soil and rocks.
Discovery of water
The southern polar region of the Moon is known to have deep craters that remain in permanent darkness, with a high likelihood of having water-ice.
Perhaps the most important discovery made by instruments on board Chandrayaan-1 was the discovery of water and hydroxyl (OH) molecules in the Moon’s thin atmosphere (exosphere) as well as on the lunar surface.
India’s Moon Impact Probe (MIP) — a payload that was deliberately crashed on the lunar surface near the South Pole — helped study the concentration of water and hydroxyl molecules in the lunar atmosphere.
Another payload called mini-SAR helped detect the subsurface deposits of water-ice in the permanently shadowed regions within the craters near the South Pole.
A third payload developed by NASA called Moon Mineralogy Mapper or M3 also helped detect these molecules on the surface of the Moon.
Chandrayaan-2, which was designed to further study the water on the Moon, helped in separately identifying the water and the hydroxyl molecules, and mapping water features across the Moon for the first time.

Chandrayaan-3 confirms Sulphur in lunar surface
GS Paper - 3 (Space Technology)
The Indian Space Research Organisation (ISRO) said the Pragyan rover's Laser-Induced Breakdown Spectroscope confirmed the presence of sulphur in the lunar surface near the south pole, through the first-ever in-situ measurements. Pragyan is a lunar rover that forms part of Chandrayaan-3, the lunar mission developed by ISRO.
More about discovery
The Laser-Induced Breakdown Spectroscopy (LIBS) instrument onboard Chandrayaan-3 Rover has made the first-ever in-situ measurements on the elemental composition of the lunar surface near the South Pole.
These in-situ measurements confirm the presence of sulphur (S) in the region unambiguously, something that was not feasible by the instruments onboard the orbiters.
LIBS is a scientific technique that analyses the composition of materials by exposing them to intense laser pulses.
A high-energy laser pulse is focused onto the surface of a material, such as a rock or soil. The laser pulse generates extremely hot and localised plasma.
The collected plasma light is spectrally resolved and detected by detectors such as Charge Coupled Devices. Since each element emits a characteristic set of wavelengths of light when it is in a plasma state, the elemental composition of the material is determined.
Chandrayaan-3 successfully executed a soft landing on the moon on 23 August 2023, making India the fourth nation in the world to achieve a successful lunar landing.
India also marked a milestone by becoming the first country to land near the South Pole, an area believed to harbour significant amounts of water ice.
ISRO on 29 August 2023 said preliminary analyses, graphically represented, have unveiled the presence of aluminium (Al), sulphur (S), calcium (Ca), iron (Fe), chromium (Cr), and titanium (Ti) on the lunar surface.
Further measurements have revealed the presence of manganese (Mn), silicon (Si), and oxygen (O). A thorough investigation regarding the presence of hydrogen is underway.
Flashback
The LIBS instrument is developed at the Laboratory for Electro-Optics Systems (LEOS) / ISRO, Bengaluru.
LEOS, situated at Peenya Industrial Estate, Bengaluru, is one of the vital units of ISRO.
It deals with the design, development, and production of attitude sensors for all low Earth orbit (LEO), geostationary Earth orbit (GEO) and interplanetary missions.
It develops and delivers optical systems for remote sensing and meteorological payloads.

The points can be used as ‘parking spots’ for spacecraft in space to remain in a fixed position with minimal fuel consumption.
They have been named after Italian-French mathematician Joseph-Louis Lagrange (1736-1813), who was the first one to find the positions. So, between the Earth and the Sun, a satellite can occupy any of five Lagrangian points. “Of the five Lagrange points, three are unstable and two are stable. The unstable Lagrange points – labelled L1, L2, and L3 – lie along the line connecting the two large masses. The stable Lagrange points – labelled L4 and L5 – form the apex of two equilateral triangles. The L4 and L5 are also called Trojan points and celestial bodies like asteroids are found here.

JAXA successful launch lander SLIM on Moon
GS Paper - 3 (Space Technology)
Indian Space Research Organisation (ISRO) congratulated Japan Aerospace Exploration Agency (JAXA) on 7 September 2023 for the successful launch of the Smart Lander for Investigating Moon (SLIM).
More about SLIM
Japan launched its H-IIA rocket on 7 September 2023 carrying the JAXA Moon lander which is scheduled to land on the Moon early next year.
The rocket carried an X-ray telescope called the X-Ray Imaging and Spectroscopy Mission (XRISM), which will study the origins of the universe. XRISM will measure the composition and speed of intergalactic space.
This space mission aims to help scientists to understand celestial object formation and the universe's creation.
This mission was conducted in collaboration with NASA, and it will involve studying light at various wavelengths, temperature assessments, and analysing the shapes and brightness of celestial objects.
Onboard the rocket is JAXA's Smart Lander for Investigating Moon (SLIM) spacecraft also known as the "Moon Sniper" for its precision landing technology.
This launch follows India's recent achievement of becoming the fourth nation to successfully land a spacecraft on the Moon with its Chandrayaan-3 mission. The launch comes two weeks after India successfully landed Vikram lander on the lunar South Pole.
Japan had previously experienced two unsuccessful attempts to land on the Moon. The first resulted in a loss of contact with a lander carried by a NASA rocket, and the second, an attempt by a Japanese start-up, ended in a crash during the lunar descent in April.

JAXA successful launch lander SLIM on Moon
GS Paper - 3 (Space Technology)
Indian Space Research Organisation (ISRO) congratulated Japan Aerospace Exploration Agency (JAXA) on 7 September 2023 for the successful launch of the Smart Lander for Investigating Moon (SLIM).
More about SLIM
Japan launched its H-IIA rocket on 7 September 2023 carrying the JAXA Moon lander which is scheduled to land on the Moon early next year.
The rocket carried an X-ray telescope called the X-Ray Imaging and Spectroscopy Mission (XRISM), which will study the origins of the universe. XRISM will measure the composition and speed of intergalactic space.
