India on Wednesday became the first nation to land a craft near the Moon's south pole, a historic triumph for the world's most populous nation and its ambitious, cut-price space program.  

The unmanned Chandrayaan-3, which means "Mooncraft" in Sanskrit, touched down at 6:04 pm India time (1234 GMT) as mission control technicians cheered wildly and embraced their colleagues.  

Its landing comes days after a Russian probe crashed in the same region and four years since the previous Indian attempt failed at the last moment.

Prime Minister Narendra Modi smiled broadly and waved an Indian flag on a live broadcast to announce the mission's success as a triumph that extended beyond his country's borders.

"On this joyous occasion I would like to address the people of the world," said Modi from the sidelines of the BRICS diplomatic summit in South Africa.

"India's successful moon mission is not just India's alone," he added. "This success belongs to all of humanity."  

The Chandrayaan-3 mission has captivated public attention since launching nearly six weeks ago in front of thousands of cheering spectators.

Politicians staged Hindu prayer rituals to wish for the mission's success and schoolchildren followed the final moments of its descent from live broadcasts in classrooms.  

"I'm so happy, nothing else has given me more happiness," Anil Kumar, a contract employee for the Indian Space Research Organization (ISRO), told AFP as his colleagues celebrated.  

"I was praying for the last 48 hours for a safe landing."

Chandrayaan-3 took much longer to reach the Moon than the Apollo missions in the 1960s and 1970s, which arrived in a matter of days.  

India used rockets much less powerful than the ones the United States used back then, meaning the probe had to orbit the Earth several times to gain speed before embarking on its month-long journey.  

The lander, Vikram, which means "valor" in Sanskrit, detached from its propulsion module last week and has been sending images of the Moon's surface since entering lunar orbit on August 5.  

Now that Vikram has landed, a solar-powered rover will explore the surface and transmit data to Earth over its two-week lifespan.  

'So much agony'  

India is closing in on milestones set by global space powers such as the United States and Russia, conducting many of its missions at much lower price tags.

The South Asian nation has a comparatively low-budget space program, but one that has grown considerably in size and momentum since it first sent a probe to orbit the Moon in 2008.  

The latest mission has a cost of $74.6 million -- far lower than those of other countries, and a testament to India's frugal space engineering.  

Experts say India can keep costs low by copying and adapting existing technology, and thanks to an abundance of highly skilled engineers who earn a fraction of their foreign counterparts' wages.  

In 2014, India became the first Asian nation to put a craft into orbit around Mars and is slated to launch a three-day crewed mission into Earth's orbit by next year.  

Wednesday's landing had been eagerly awaited by ISRO after the frustrating failure of its previous mission at the last hurdle in 2019.

Back then, mission control lost contact with the Chandrayaan-2 lunar module moments before its slated landing.  

ISRO chief S. Somanath said that many of those who worked on the 2019 mission were involved in the current endeavor, and that the successful touchdown had vindicated their years of effort.  

"They went through so much agony to find out what went wrong," he said. "My salutations to all of those unsung heroes today."  

'Very, very important'

Former ISRO chief K. Sivan told AFP that India's efforts to explore the relatively unmapped lunar south pole would make a "very, very important" contribution to scientific knowledge.  

Only Russia, the United States and China have previously achieved controlled landings on the Moon.  

Russia launched a lunar probe in August -- its first in nearly half a century.  

If successful, it would have beaten Chandrayaan-3 by a matter of days to become the first mission from any nation to make a controlled landing around the south pole.  

But Luna-25 crashed on Saturday after an unspecified incident as it prepared to descend.

A scientist guides a long tube into the mouth and down to the stomach of Thing 1, a two-month-old calf that is part of a research project aiming to prevent cows from burping methane, a potent greenhouse gas.

Paulo de Meo Filho, a postdoctoral researcher at University of California, Davis, is part of an ambitious experiment aiming to develop a pill to transform cow gut bacteria so it emits less or no methane.

While the fossil fuel industry and some natural sources emit methane, cattle farming has become a major climate concern due to the sheer volume of the cows' emissions.

"Almost half of the increase in (global) temperature that we've had so far, it's been because of methane," said Ermias Kebreab, an animal science professor at UC Davis.

Methane, the second largest contributor to climate change after carbon dioxide, breaks down faster than CO2 but is more potent.

"Methane lives in the atmosphere for about 12 years" unlike carbon dioxide which persists for centuries, Kebreab said.

"If you start reducing methane now, we can actually see the effect on the temperature very quickly."

Filho uses the tube to extract liquid from Thing 1's rumen -- the first stomach compartment containing partially digested food.

Using the rumen liquid samples, the scientists are studying the microbes that convert hydrogen into methane, which is not digested by the cow but instead burped out.

A single cow will burp roughly 220 pounds (100 kilograms) of the gas annually.

- 'Social critters' -

Thing 1 and other calves receive a seaweed-supplemented diet to reduce methane production.

Scientists hope to achieve similar results by introducing genetically modified microbes that soak up hydrogen, starving methane-producing bacteria at the source.

However, the team proceeds cautiously.

"We can't just simply cut down methane production by removing" methane-making bacteria, as hydrogen could accumulate to the point of harming the animal, warned Matthias Hess, who runs the UC Davis lab.

"Microbes are kind of social critters. They really like to live together," he said.

"The way they interact and affect each other impacts the overall function of the ecosystem."

Hess's students test different formulas in bioreactors, vessels that reproduce microorganisms' living conditions in a stomach from movements to temperature.

- More productive cows -

The project is being carried out at UC Davis as well as UC Berkeley's Innovative Genomics Institute (IGI).

IGI scientists are trying to identify the right microbe -- the one they hope to genetically alter to supplant methane-producing microbes.

The modified microorganisms will then be tested at UC Davis in the lab and in the animals.

"Not only are we trying to reduce methane emissions, but you also increase the feed efficiency," said Kebreab.

"Hydrogen and methane, they are both energy, and so if you reduce that energy and redirect it to something else... we have a better productivity and lower emissions at the same time."

The ultimate goal is a single-dose treatment administered early in life, since most cattle graze freely and can't receive daily supplements.

The three research teams have been given $70 million and seven years to achieve a breakthrough.

Kebreab has long studied sustainable livestock practices and pushes back against calls to reduce meat consumption to save the planet.

While acknowledging this might work for healthy adults in developed nations, he pointed to countries like Indonesia, where the government is seeking to increase meat and dairy production because 20 percent of children under five suffer from stunted growth.

"We can't tell them to not eat meat," he said.
