After 47 years, Russia is&nbsp;gearing up for its&nbsp;first lunar landing mission,&nbsp;Luna-25, which is nearing the moon. The mission comes at a time when Chandrayaan-3’s landing date is also approaching. Its arrival on the moon's surface could happen in a timeframe that is nearly identical to Chandrayaan-3's or even slightly faster.&nbsp;

As Chandrayaan-3 continues to draw closer to its targeted lunar touchdown, another contender in lunar exploration, Luna-25, the Russian lunar mission launched just last week, has successfully entered lunar orbit and is gearing up for a soft landing attempt on the lunar surface between August 21 and 23. This timing potentially positions Luna-25 ahead of Chandrayaan-3's planned touchdown on August 23.

<h2>When will Russia's Luna-25 land on the moon?</h2>

The launch happened from Russia's spaceport, Vostochny Cosmodrome, 3,450 miles (5,550 km) east of Moscow and was to take considerably less time than India's Chandrayaan-3.&nbsp;

The Russian space agency Roscosmos has told Reuters that its Luna-25 spacecraft would take five days to fly to the moon and then spend five to seven days in lunar orbit before descending on one of the three possible landing sites near the pole.

Earlier on August 8, ISRO chairman S Somanath said that Vikram, the lander of India’s third lunar mission Chandrayaan-3, will be able to make a soft landing on the Moon's surface on August 23 even if all the sensors and two of its engines do not work.

<h2>Will the two lunar missions get in each other’s way?</h2>

Roscosmos has said that the two missions would not get in each other's way because they have different landing areas planned, Reuters has reported. "There is no danger that they interfere with each other or collide. There is enough space for everyone on the moon," it said as quoted by Reuters.

India's Chandrayaan-3 is due to run experiments for two weeks while Luna-25 will work on the moon for a year. With a mass of 1.8 tonnes&nbsp;and carrying 31 kg (68 pounds) of scientific equipment, Luna-25 will use a scoop to take rock samples from a depth of up to 15 cm (6 inches) to test for the presence of frozen water that could support human life.

Originally scheduled for October 2021, Luna-25's launch was postponed by over two years. The European Space Agency (ESA) intended to test its Pilot-D guidance camera by mounting it to Luna-25. However, after Russia invaded Ukraine in February of last year, the ESA severed its ties to the project.

Chandrayaan-3 vs Russia's Luna-25: Will the two lunar missions get in each other’s way?

Russia,on Monday (August 7) said it plans to launch a lunar lander later this week after multiple delays, in a bid to return to the Moon for the first time in half a century. Ahead of the launch scheduled for Friday, Moscow officials also said they would evacuate a village in the country’s far east.&nbsp;

<h2>About the Russian moon mission</h2>

In an update the Russian space agency, Roscosmos, said on Monday, “A Soyuz (rocket) for the launch of the Luna-25 (lander) has been assembled.” It added, “The launch is on August 11.”&nbsp;

Russia is set to return to the moon with its Luna-25 lunar lander for the first time since 1976.&nbsp;

<h2>Why is the Russian village being evacuated?</h2>

The evacuation will take place in Russia’s Shakhtinsky settlement in the Khabarovsk region, southeast of the launch site on Friday as it lies in the predicted area where the rocket boosters will fall after they separate, according to the local official.&nbsp;

“The mouth of the Umalta, Ussamakh, Lepikan, Tastakh, Saganar rivers and the area of the ferry crossing on the Bureya River fall into the predicted (booster) fall zone,” said Alexei Maslov, head of the Verkhnebureinsky district in the Khabarovsk region, on messaging app, Telegram.&nbsp;

Russia to evacuate village ahead of first lunar mission launch in 50 years: Here's why

An unexplained pressure was reported on Saturday in a Russian spacecraft, docked with the International Space Station (ISS). On Telegram, Russian space agency Roscosmos revealed that a Progress cargo ship had lost cabin pressure. It was docked with the ISS and is due to undock from the ISS on February 18.&nbsp;

The Roscosmos stated that a depressurisation in the cooling system of the Progress MS-21 cargo ship was detected by the mission control specialists.&nbsp;

According to the Russian space agency, the exact reason behind the incident was being investigated and the vessel was sealed off from the rest of the station.&nbsp;

Roscosmos said: "The temperature regime and pressure on board the ISS are normal, nothing threatens the life and health of the crew and they feel fine."&nbsp;

NASA later said the depressurisation was due to a coolant leak. NASA said, "The reason for the loss of coolant in the Progress 82 spacecraft is being investigated."&nbsp;

It added, "The hatches between Progress 82 and the station are open, and temperatures and pressures aboard the station are all normal. The crew, which was informed of the cooling loop leak, is in no danger and continuing with normal space station operations."&nbsp;

'A casus belli': Amid Ukraine crisis, Russia space agency head says satellite hacking would justify war

According to the Russian Space Agency, India’s Cartosat 2F weighing over 700kg dangerously approached the Kanopus-V spacecraft at 01:49UTC, on Friday, November 27. In a tweet, Roscosmos has said that the minimum distance between both Russian and foreign satellite was 224 meters. Both the satellites are meant for earth’s remote sensing.&nbsp;

How significant and dangerous is this?&nbsp;

According to a source that spoke to WION on the condition of anonymity, 1 kilometre is an ideal distance between satellites in orbit, whereas 224 meter is scary and can be counted as a near miss. Generally, when two satellites are predicted (based on calculations) to make a close pass, a decision is taken to manoeuvre one of them away in advance (usually days ahead).&nbsp;

Also read|&nbsp;<a href="https://www.wionews.com/india-news/indias-proposed-venus-mission-attracts-international-payload-proposals-344846">India's proposed Venus mission attracts international payload proposals</a>

Given how space is getting increasingly crowded with satellites that are used for various purposes, it is said to be normal for agencies to manoeuvre one of their satellites every 3-4 weeks. It is notable that low Earth orbit (500-2000km) is the most congested, with satellites of various sizes — ranging from 10cm cubes to ones that are the size of a car or larger.&nbsp;

However, the decision to manoeuvre is not very easy. Especially, when the satellite is performing a strategic role that requires it to be at a particular spot. Because the manoeuvre would affect the schedule of the pre-planned operation of surveillance (in whatever form). In this case, Roscosmos has said that both are remote sensing satellites, which implies that they in all likelihood used for strategic purposes.&nbsp;

The space community has been divided over the prediction models for tracking satellites in orbit. The existing ones are the European Model, American model, Russian model, whereas the Indian model is under development. The reason that the space community hotly debates the efficiency of the models is that there are differences between the calculations made using each model.&nbsp;

Let’s assume, in this case, the Indian model said that the satellites would be 1km apart, whereas the Russian model would have predicted that they would be 500m apart. It is also highly likely that in reality, both models went wrong and the satellites get closer than the prediction showed. Hence, there is no single model that works accurately, as each one can provide a different result. Another factor that could impact prediction models in low earth orbits is the impact of the drag from the Earth's atmosphere.&nbsp;

Some interesting questions in this scenario are - how or why did the respective agencies allow the satellites to get this close? Were there predictions that both sides performed? Given the close Indo-Russian cooperation on space technology, did the agencies foresee this close shave and coordinate? &nbsp;

Most importantly, why would the Russian agency go public with this information, rather than discuss with ISRO officials. Or did both the agencies have critical strategic functions that required the satellites to remain exactly in their respective orbits, despite knowing that they would make a close pass.&nbsp;

Is it possible that the agencies wanted to allow a close pass and then take a call on any possible manoeuvre in future? &nbsp;

The real danger posed by a possible collision of satellites would be the debris of varying sizes scattered across space in all directions, in high-speeds with high potential of harming other satellites.&nbsp;

The last large collision of satellites happened in 2009, when a US commercial Iridium spacecraft hit a defunct Russian satellite over Siberia, producing thousands of pieces of debris.

As of January 2020, there are around 2,000 active satellites orbiting the earth. There are also more than 23,000 pieces of debris larger than 10cm (4inches) in orbit, according to NASA.

According to the Russian Space Agency, India’s Cartosat 2F weighing over 700kg dangerously approached the Kanopus-V spacecraft at 01:49UTC, on Friday, November 27.

According to the Russian Space Agency, India’s Cartosat 2F weighing over 700kg dangerously approached the Kanopus-V spacecraft at 01:49UTC, on Friday, November 27. In a tweet, Roscosmos has said that the minimum distance between both Russian and foreign satellite was 224 meters. Both the satellites are meant for earth’s remote sensing. How significant and dangerous is this? According to a source that spoke to WION on the condition of anonymity, 1 kilometre is an ideal distance between satellites in orbit, whereas 224 meter is scary and can be counted as a near miss. Generally, when two satellites are predicted (based on calculations) to make a close pass, a decision is taken to manoeuvre one of them away in advance (usually days ahead).

It is notable that low Earth orbit (500-2000km) is the most congested, with satellites of various sizes — ranging from 10cm cubes to ones that are the size of a car or larger. However, the decision to manoeuvre is not very easy. Especially, when the satellite is performing a strategic role that requires it to be at a particular spot. Because the manoeuvre would affect the schedule of the pre-planned operation of surveillance (in whatever form). In this case, Roscosmos has said that both are remote sensing satellites, which implies that they in all likelihood used for strategic purposes. The space community has been divided over the prediction models for tracking satellites in orbit. The existing ones are the European Model, American model, Russian model, whereas the Indian model is under development. The reason that the space community hotly debates the efficiency of the models is that there are differences between the calculations made using each model.

Indian ISRO satellite flew dangerously close to Russian sat, says Roscosmos

A three-person crew has successfully docked at the International Space Station (ISS) on Wednesday, the Russian space agency&nbsp;Roscosmos confirmed.

The manner aircraft&nbsp;SoyuzMS17 successfully docked to the&nbsp;to the Russian segment of the International Space Station. It launched from Baikonur cosmodrome and had&nbsp;Roscosmos cosmonauts Sergey Ryzhikov, Sergey Kud-Sverchkov and&nbsp;NASA astronaut Kathleen Rubins on board.

It has become the first spacecraft in the world that&nbsp;made only two orbits around the Earth. This was also the first time ever that a spacecraft took&nbsp;"a record short three hours and three minutes."

Explaining about the mission, the International Space Station tweeted, "The Exp 64 crew will soon board the station to begin a six-month research mission after the hatch opens at about 6:45am ET."

As per reports, this is also being reported as the last Russian flight to carry a US crew member.&nbsp;“We have an incredible partnership,” Rubins said in an interview from Russia's Star City before her flight. “We'll continue to train crews over here and we're going to have cosmonauts come to the Johnson Space Center and train.”

The launch also co-incided with Kathleen Rubins' birthday.

Russian authorities have detained a former journalist and a close aide to the head of Russia's space agency Roscosmos on Tuesday on treason charges, as per the agency. Also read: Exiled Uighurs approach ICC for seeking justice against Chinese 'genocide' Roscosmos have said that the probe against Ivan Safranov is underway and that he was "fully cooperating with the investigative authorities". According to the reports, Safronov's detention was not linked with his work for Roscosmos, where he worked as an advisor to General Director Dmitry Rogozin. A source told news agency Interfax that Safronov's detention could be linked to his earlier work in journalism and that he did not have clearance to access state secrets as a Roscomos employee. Safranov is expected to appear in the court later on Tuesday. Ivan Safronov worked in Russian daily newspapers Kommersant and Vedomosti he used to report on politics, the military, and Russia's space programmes. In 2019, Kommersant removed from its website an article co-authored by Safronov about the delivery of Russian jets to Egypt after court proceedings into the disclosure of state secrets. He was forced to resign from Kommersant in May last year after a report alleging the speaker of Russia's upper house of parliament was planning to step down. The entire politics desk of the newspaper resigned in protest against the dismissal of Safronov and another colleague whose name appeared on the story. (Inputs from AFP)
