China-Singapore, Beijing, July 16 (Reporter Sun Zifa) Springer Nature’s professional academic journal “Nature Astronomy” recently published a planetary science paper saying that researchers have discovered a potentially accessible underground tunnel originating from an open pit on the moon. Evidence of tunnel. The results of this study have enhanced people’s understanding of lunar geology and may become an ideal location for a lunar base, thus potentially serving as a refuge in future manned missions on the lunar surface.

The paper said that more than 200 craters known as skylights have been discovered on the lunar surface, some of which were formed after the collapse of underground lava tubes. Accessible lava tubes or channels may provide a warmer environment than the lunar surface, but it has previously been uncertain whether they can lead to large underground caves.

In this study, co-authors of the paper, LC and LB of the University of Trento in Italy, and collaborators, analyzed radar data from the Lunar Reconnaissance Orbiter and found that radar brightness on the west side of the crater increased. Jinghai Crater is the deepest known crater on the moon, with a radius of approximately 100 meters, with vertical or overhanging walls and a sloping bottom.

The authors of the paper used radar images to conduct simulations and found that these observations could be explained by the presence of a cave void or pipe spreading from the west side of the bottom of the pit. They estimate that the pipeline is located at a depth of 130-170 meters, 30-80 meters long and about 45 meters wide. The cave may be flat or inclined at an angle of up to 45 degrees and may be accessible.

The authors concluded that the pipes or channels discovered in this study may be a common feature under the lunar plains, and that the Jinghai Pit and its channels may be an ideal site for a potential lunar base. The method used in the study may also be suitable for evaluating and characterizing other lunar craters to discover more channels.

Paris, July 16 (Reporter Qiao Benxiao) The French Presidential Palace issued an announcement on the 16th saying that President Macron approved Prime Minister Attar’s resignation request on the same day and asked the Attar government to continue to handle daily government affairs before the new government is established.

The French Constitution and laws have no relevant provisions on the time when the president appoints the prime minister. The presidential palace announcement called on all mainstream parties to work together to establish alliances to end the transition period as soon as possible. In an open letter, Macron had previously called for mainstream parties to engage in dialogue and said he would appoint a new prime minister based on mainstream consensus.

On the 7th of this month, France held the second round of voting in the National Assembly election. According to French political tradition, after the National Assembly election, the Prime Minister will submit his resignation to the President regardless of the election outcome. On the 8th, Atar submitted his resignation to Macron, but was asked to stay in office temporarily to ensure national stability.

France’s new National Assembly is scheduled to hold its first plenary session on the 18th of this month and will elect a new speaker. After Attar’s resignation is approved, members of the elected members of Attar’s government can concurrently serve in the National Assembly. Attar himself was also elected to parliament.

Russian President Vladimir Putin said on the 13th that he would redeploy troops on the border between Russia and Finland in response to Finland’s accession to NATO, UPI reported on March 13.

Reported that Putin said in an interview with Russian state media that from the perspective of safeguarding national interests, the actions of Finland and Sweden are absolutely meaningless.

We used to have a good relationship with Finland on the whole, he said. It’s perfect. The two countries do not covet each other, especially territorial claims, let alone other areas. We didn’t even have troops at the border; we withdrew all our troops from the Finnish border.

But this is their decision, Putin said. Now that they have decided that we did not have troops there in the past, we will have them now.

It is reported that in 2022, shortly after Russia sent troops to Ukraine, Finland and Sweden applied to join NATO. Finland became a member of NATO in April last year, and Sweden did not formally join until last week because of opposition from Hungary and Turkey.

Putin’s remarks came after Finnish Prime Minister Peter Riolpo told the European Parliament in Strasbourg that other EU countries must follow Finland’s example and strengthen security in marginal areas. (compiled by Wang Dongdong)

Putin warns the West: ready for nuclear war

Russian President Vladimir Putin has warned the West that Russia is technically ready for a nuclear war and that if the United States sends troops to Ukraine, it will be seen as a major escalation of the war, Reuters reported on March 13.

Putin accepted a joint interview with Russia-1 Channel and Russian News Agency on the 12th. The program about this interview was officially broadcast on the 13th.

In response to the question of whether Russia is really ready to fight a nuclear war, Putin said: from the perspective of military technology, we are certainly ready, the report said.

Putin pointed out that the United States understands that if it deploys US troops on Russian territory or in Ukraine, Russia will regard this as intervention. So while I don’t think it’s all in a hurry to [nuclear confrontation” target=_blank>, we are ready for it, he said.

The conflict in Ukraine triggered the most serious crisis in relations between Russia and the West since the Cuban missile crisis in 1962. Putin has repeatedly warned that if the West sends troops to fight in Ukraine, it could lead to a nuclear war.

In the interview, Putin reiterated that the use of nuclear weapons is something already stated in the Kremlin’s nuclear policy, which sets out the possible use of nuclear weapons by Russia.

Putin said: weapons exist to use them. We have our own principles.

The report also said that for the conflict in Ukraine, which has lasted for two years, Putin said that Russia is ready to hold serious talks on the Ukraine issue.

Putin said: Russia is ready to negotiate on Ukraine, but the negotiations should be based on reality, not on desire after the use of psychotropic substances.

Reuters reported last month that Putin’s proposal to cease fire in Ukraine to freeze the war was rejected by the United States after middlemen between Russia and the United States.

According to the report, he also said in an interview that if the United States conducts a nuclear test, Russia may do the same.

We may not have to consider this issue, but I do not rule out the possibility that we will do the same, he said. (compiled by Longjun)
