Did ISRO seek advice from Israel?

Although India may have missed the historic moment, the mission of Chandrayaan-2 is being appreciated worldwide.
India tried to release a lander 'Vikram' from Chandrayaan-2's orbiter near the south pole of the moon's surface, but lost contact on Saturday morning.
At this time the lander 'Vikram' was only 2.1 kilometers away from the surface of the moon. So far, ISRO has not announced that the 'record' has been destroyed.
Vikram's life is 14 days and Esro still hopes he can be approached again.
In praise of ISRO's efforts, the US space agency NASA wrote:
"Space is very difficult. We applaud Isro's attempt to land Chandrayaan-2 at the south pole of the Moon's surface. We are all inspired by ISRO's efforts. Now ISRO should look to the future opportunity, so that we can work together on the solar system. "
Twitter post by @NASA: Space is hard.  We commend @ ISRO's attempt to land their # Chandrayaan2 mission on the Moon's South Pole.  You are inspired by our journey and look forward to future opportunities to explore our solar system together.
The Chandrayaan-2 trip is not over yet, as the orbiter is doing his job. Orbiter's one year long Moon mission has just begun.
He entered the Moon's orbit just last month.
Chandrayaan-2's orbiter has eight different scientific instruments. He is studying satellites.
ISRO officials say its data will help searchers know the moon's surface map.
The map can estimate the water on the moon. A decade ago, Chandrayaan-1's orbiter said that the water in the southern pole on the surface of the moon is spreading far and wide.
NASA praised the study of Chandrayaan-1.
So it was decided to send Chandrayaan-2 to the southern pole of the Moon.
NASA, however, is working on a plan to send two astronauts to the South Pole on the surface of the moon by 2024.

Partial failure

The New York Times writes that this is partly a failure, because the orbiter is doing its job.
The newspaper writes that the reason for the failure to establish contact may be the crash of the spacecraft. Dr. Sewan said the last 15 minutes were filled with horror.
This year, there were three attempts to launch the spacecraft to the moon.
In January, China was successful in such a mission. In April this year, Israel sent a small robotic spacecraft called the Bersheet to the moon, but failed like the Chandrayan-2.
His contact with the moon's surface was broken. Then it was reported that one of the engine commands was wrong.
The New York Times wrote in a report, "Lander's record was reaching 3218 kilometers per hour for 15 minutes before landing on the moon's surface." His engine was going to slow down, landing at the south pole of the moon's surface. "
"But at the time of landing, Vikram's speed was too low and this time he lost contact with the ground station."
Israel's 'Baresheet' and India's 'Chandrayan-2' were low-cost campaigns.
The brackets cost $ 10 million and Chandrayaan had $ 15 million.
Both missions were much cheaper compared to the missions of NASA and the European Space Agency.
NASA launches affordable 'Robotic Moon Mission' in 2021 to reach the moon.
Low cost campaign
Given the failures of cheap missions in India and Israel, it is said that such missions are at greater risk of failure, so NASA may also rethink less expensive missions.
Israel's 'Bearsheet' spacecraft was created by Space Space and Israel Aerospace Industries (IAI).
Attempts were made to land him softly on the surface of the moon, but he was traumatized.
The campaign also lost contact with the ground.
On the failure of the campaign, Israeli Prime Minister Benjamin Netanyahu said, "If you are not successful the first time, you should try a second time."
The Prime Minister of Israel also visited the 'SpaceIL Control Center' in Judah during the landing of the campaign on the night of April 11.
At that time, Israel too missed entering the list of Moon-landing countries such as Russia, America and China, and so has India.
The Indian Prime Minister also said like Netanyahu that 'there is no such thing as failure in science, because every experiment teaches something.'
Meanwhile, ISRO said on Sunday that Chandrayaan-2's orbiter had seen a 'Vikram' lander on the surface of the moon, but no signal was being received from it.

Further preparation

ISRO President That Sivan said, "An attempt has been made to contact Vikram". We hope to reach 'Vikram' in the next 14 days. Vikram's life is only 14 days.
National Geographic wrote on the incident of losing contact with 'Vikram' lander, '' Vikram's flight was very difficult. Speed ​​should be fairly slow when landing on the surface of the Moon. Failure to reach the moon has been found during most of the expeditions. "
According to NASA, 109 expeditions were launched to reach the moon since 1958, of which only 61 were successful.
During 46 expeditions, attempts were made to land on the moon, only 21 were successful.
Both NASA and ISRO are planning to send humans to the moon in the coming days.
There is talk of a long distance rover landing between India and Japan at the South Pole on the surface of the moon during the year 2023. The purpose of this expedition will be to find water on the moon.
"Comparison of Israel Bareshit and India's Chandrayan-2 can be made on the basis that both campaigns failed to land on the surface of the moon," says Pallava Bagla, a journalist writing on science.
They say that Israeli Prime Minister Netanyahu was also present in the country's center of affairs and wanted to witness a successful campaign, but that could not happen.
Modi also wanted to be a witness to the historic success of Chandrayaan-2, but that was not possible.
Dr. That When asked about the failure of Israel in Siwan, he said his team had studied the matter.
Bagla adds, "The difference between India and Israel's expeditions was that their contact was broken when Chandrayan-2 was only 2.1 kilometers away from the surface of the moon, while the Bareshit crashed when the moon's surface was 22 kilometers away."
