Not the Indian space craft just sent to moon...

Modi laughing
India's on the way...

Country’s space agency Roskosmos space agency reported. Abnormal situation’ as Luna-25 tries to begin moon landing. Luna-25 craft on 10 August was Russia’s first since 1976. Only three govts managed successful moon landings: Soviet Union, US & China. While India and Russia are aiming to be first to land at the moon’s south pole.

The Indian Space Research Organisation (ISRO) plans to have their Chandrayaan-3 lander and rover touch down near the lunar south pole region at 5.47 p.m. on August 23.

Chandrayaan-3 LIVE updates: ISRO's Chandrayaan-3 is about to complete its over a month long journey from Earth on Wednesday after being launched on July 14. 

Monday said a two-way communication between the Chandrayaan-2 orbiter and Chandrayaan-3's lander module has been established. 

"‘Welcome, buddy!’ Ch-2 orbiter formally welcomed Ch-3 LM. Two-way communication between the two is established. MOX has now more routes to reach the LM," the space agency said in a post on X (formerly Twitter).

On Sunday,  ISRO announced that the lander module of Chandrayaan-3, the third lunar mission of India, is expected to touch down on the surface of the Moon around 6.04 pm on August 23.

The live telecast of the landing event will begin at 5.20 pm on Wednesday (August 23).

I guess the Russian spacecraft could have been sabotaged, causing one of its stabilising rockets to fire and going into a spin.
(Like a Russian rocket that crashed during launch years ago as one of its angular velocity sensors was installed upside down)

As for the Indian moon lander, its success is still a big unknown.
Even for the initial Earth launching where there are many Earth-based position trackers, the Indian rocket had failed to enter the desired earth orbit accurately, resulting in the transport module burning more fuel than expected for more orbit corrections before its Earth-moon transfer. This resulted in lesser fuel for braking when entering the moon orbit, and the moon lander was thus ejected (separated) at a higher 153 x 163km moon orbit instead of the planned 100 x 100km circular orbit. 

Thus I believe there will be higher chance of "error" or inaccuracy when the lander does an autonomous braking for landing (just like shooting a pistol at 100m vs 150m).

This year is the 2nd attempt by the Indians to do a soft landing on the Moon.
Last one was Chandrayaan-2 when its Vikram Lander lost control just < 3km above the surface and crashed in 2019.
Japan and Israel tried too and fail....

Not easy.

On the 109 lunar missions during the period, 61 were successful and 48 had failed, it stated.7 Sept 2019

40 per cent lunar missions in last 60 years failed: NASA fact sheet


China (late space race to Moon) – it didn't send its first satellite into orbit until 1970, by which time the US had a astronaut on the moon – but Beijing has been catching up fast. In 2013, China successfully landed a rover on the moon, becoming only the third country to do so.13 Jul 2023.

For India, a successful moon landing would mark its emergence as a space power as Prime Minister Narendra Modi's government looks to spur investment in private space launches and related satellite-based businesses.

"If Chandrayaan-3 succeeds, it will boost India's space agency's reputation worldwide. It will show that India is becoming a key player in space exploration

WHAT MAKES THE SOUTH POLE ESPECIALLY TRICKY?

Attempted landings on the moon have failed before. Russia's Luna-25 craft had been scheduled to land on the south pole this week but spun out of control on approach and crashed on Sunday.

The south pole - far from the equatorial region targeted by previous missions, including the crewed Apollo landings - is full of craters and deep trenches.

ISRO's Chandrayaan-3 mission is on track for an attempted landing on Wednesday, the space agency has said. A previous Indian mission failed in 2019 to safely land near the area targeted by Chandrayaan-3.

Both United States and China have planned missions to the south pole. Resently Russia try, a big X. 100% failure, it was see to be kana  sabotbidage (deliberately and destroy)

Indian PM Modi says mission’s success “belongs to all of humanity.”
Chandrayaan-3 – “Mooncraft” in Sanskrit – took off from a launchpad in Sriharikota in southern India on July 14.
Scientists believe the south pole’s unchartered territory could hold important reserves of frozen water and precious elements.
In India, people have crowded around televisions in offices, shops, restaurants and homes to watch the moon landing live.

It is unfortunate that we have become territorial and so we say, the Russians tried but crashed, India is the first country to succeed, China and the US had plans to do it but India got there first 

Modi is right. It belongs to humanity.

Just a simple thing like food, which meat, which plant or vegetable or mushrooms can be eaten, which is poisonous......someone had paid with his life for the rest to know. We don't ask about the deceased's nationality, we just eat and enjoy.

Errr.. the Devils are in the Details - Majority of those 61 successes were credit to Soviet and US between 1959-72.

Only 5% were by the Chinese with their 3 Chang'e lunar soft landings achieved in the last 1 decade with 100% success...

And unlike in the 20th century, since the start of this Century, no Western country is able to soft-land a spacecraft on the Moon ..Only 2 Asians countries have done that until yesterday.

In any new frontiers, it is certainly a bragging right to claim to be the "first" in ANYTHING.

Soviet and US had their days of achieving many "First" in Lunar explorations, including the famous "For all Humanity" during Armstrong landing in 1969...

So Modi isn't the "first" to make such politically-correct statement...

Now now! What nonsense are you on about this time huh?

The first person to land on the moon landed there 2000 years ago. It was during the Han period, yes HAN 汉 between BC 206 and AD 200, the age of Buddhism in China.

If you stare at the moon long enough, you can see her. Guess what's her name and nationality...?

Meanwhile in US...SPACE...News.

New Horizons is about to leave the solar system. Only four spacecraft have ever done that before.

Here's What We Know
Outside our star system, the space probe will be able to take pictures of the universe without light. New Horizons has reached the edge of the solar system and has already transmitted several photos to scientists.

Thanks to the spacecraft, researchers have learnt that the sky at the edge of the system is not as dark as previously thought. The light turned out to be twice as intense as scientists had calculated by analysing the light of galaxies that are located in the direction of the survey. Moreover, New Horizons took the photo in the darkest side of the Milky Way to minimise the background glow.

As they wrote above, only four spacecraft were able to leave the solar system. Previously, this was done by Pioneer 10 and Pioneer 11 and Voyager 1 and Voyager 2. 

By the way, recently scientists lost and then successfully re-established contact with Voyager 2, which has removed about 20 billion kilometres from our planet.

As usual Oyk is back again with his usual rich imaginary makeup-story that is far removed from a reality that "2000 years ago"  Buddhism was born in a region we called "India"  today which oddly now has < 1% practicing Buddhism. 

I am sure Modi himself won't say "Now now" and call that FACT as "nonsense".

...and in between the years after those 4 deep-space probes were launched from Earth till 2016, the US had lost interest in Moon exploration.
We had to wait for 45 years after the last Apollo mission, when an eccentric POTUS Trump decided to refocus America's interest back to the Moon leading to Artemis program in 2017 ..Why ?
