Russia moon probe crash likely left 33-foot-wide crater on the lunar surface, NASA images show_我的网站

一 |     Russia's Luna-25 probe likely left a 33-foot-wide crater on the surface of the moon last month when it lost control and crashed down, NASA said Thursday, revealing images that show the suspected impact site.Russia's first moon mission in 47 years ended in failure on August 19 when the Luna-25 probe smashed into the moon after a thruster firing went awry, cutting off communications and putting the spacecraft on the wrong orbital path, according to Roscosmos, the Russian space agency.NASA's Lunar Reconnaissance Orbiter (LRO) spacecraft captured images last week of what the U.S. space agency described as a "new crater" after Roscosmos published an estimate of where the probe had struck.

             

"Since this new crater is close to the Luna-25 estimated impact point," NASA wrote in a statement, "the LRO team concludes it is likely to be from that mission, rather than a natural impactor."      Moscow has set up a commission to investigate exactly why Luna-25 crashed.The failure was a major disappointment for the Russian space program, which was attempting to up its game amid renewed interest in the moon's southern polar region, where ice deposits may exist in permanently shadowed craters. Ice could offer future space missions a way to produce breathable air, water and even hydrogen rocket fuel.                 The Russians have had little success with independent space exploration since the Luna-24 robot landed on the moon in 1976. It scooped up about six ounces of lunar soil and returned it to Earth in Russia's third successful robotic lunar sample return mission.Twelve NASA astronauts walked on the moon a half century ago in the agency's Apollo program, but no Russian cosmonauts ever made the trip. Russia's only previous post-Soviet deep space robotic missions, both targeting Mars, ended in failure.

    

                                                     

    

Luna-25 was an attempt to pick up the torch and put Russia back into a new space race of sorts, as the U.S., China, India, Japan and the private sector all plan multiple moon missions that could lay the foundations for lunar bases and eventual flights to Mars.India's Chandrayaan-3 Vikram lunar lander made a historic touch-down near the moon's south pole just several days after the Russian probe crashed. It delivered a lunar rover that has already sent back data from soil samples.                      William Harwood contributed to this report.

。    Pyongyang, Oct 10 (UNI) North Korea on Monday said its recent barrage of missile launches were actually nuclear attack simulation on the South.

It comes as intelligence suggests North Korea is preparing to hold its first nuclear weapon test in five years, the BBC reported.

In recent weeks, Pyongyang has launched seven sets of missiles in response to recent US and South Korea drills.

On Monday, state media published extensive reports claiming the missiles were designed to carry tactical nuclear weapons.

These are small short-range weapons intended for use on the battlefield. They said the military practised loading the missiles with dummy versions of these miniaturised warheads.

They also claimed to have successfully simulated hitting South Korea's military bases, ports and airports, and said the launches were a warning to US and South Korea.

State news agency KNCA ran photos of leader Kim Jong-un overseeing and "guiding" the tests.

US and South Korea intelligence officials have been suggesting that the North may soon test a nuclear weapon for the first time since 2017.

Experts believe it could also use the opportunity to detonate a smaller tactical device for the first time - the sort which would fit into the missiles it has been testing, the BBC reported.

Last month Kim declared North Korea an "irreversible" nuclear power and revised its laws, allowing it to use nuclear weapons pre-emptively. Its previous policy had been to only use such weapons in response to an attack.

It has also markedly stepped up its frequency of missile firings this year, carrying out over 40 missile launches this year so far - its most ever.

Most of the launches in the past fortnight have been short-range missiles, which landed in the sea between North Korea and Japan.

But North Korea also fired a longer-distance missile over Japan last Tuesday - which analysts say is a new intermediate-range ballistic missile, based on the weapon's design.

This year has seen the North test-fire missiles from a variety of launch sites including trains and convoys - moving platforms which would make it harder for the weapons to be destroyed in a strike, analysts have suggested.

The analysts told BBC that Monday's state media reports framed the recent launches as "tactical nuclear operations units" - instead of describing them purely as missile tests - suggesting that North Korea has now developed a system for deploying smaller, short-range nuclear weapons.

The 25 September-October 9 barrage were a response to the US deploying its nuclear-powered aircraft carrier the USS Ronald Reagan to waters around the Korean peninsula, and holding joint drills with Seoul and Tokyo.

The acceleration marks a significant change from when Pyongyang pursued denuclearisation talks with then US President Donald Trump between 2018 and 2019.

Analysts also said North Korea is also reacting to South Korean President Yoon Suk-yeol's hawkish stance to the North and closer ties with the US.
