Scientists have confirmed a cave on the moon that could be used to shelter future explorers
Cape Canaveral, Jul 15: Scientists have confirmed a cave on the moon, not far from where Neil Armstrong and Buzz Aldrin landed 55 years ago, and suspect there are hundreds more that could house future astronauts.
An Italian-led team reported Monday that there's evidence for a sizable cave accessible from the deepest known pit on the moon. It's located at the Sea of Tranquility, just 250 miles (400 kilometers) from Apollo 11's landing site.
The pit, like the more than 200 others discovered up there, was created by the collapse of a lava tube.
Researchers analyzed radar measurements by NASA's Lunar Reconnaissance Orbiter, and compared the results with lava tubes on Earth. Their findings appeared in the journal Nature Astronomy.
The radar data reveals only the initial part of the underground cavity, according to the scientists. They estimate it's at least 130 feet (40 metres) wide and tens of yards (metres) long, probably more.
“Lunar caves have remained a mystery for over 50 years. So it was exciting to be able to finally prove the existence" of one, Leonardo Carrer and Lorenzo Bruzzone of the University of Trento, wrote in an email.
Most of the pits seem to be located in the moon's ancient lava plains, according to the scientists. There also could be some at the moon's south pole, the planned location of NASA's astronaut landings later this decade. Permanently shadowed craters there are believed to hold frozen water that could provide drinking water and rocket fuel.
During NASA's Apollo program, 12 astronauts landed on the moon, beginning with Armstrong and Aldrin on July 20, 1969.
The findings suggest there could be hundreds of pits on the moon and thousands of lava tubes. Such places could serve as a natural shelter for astronauts, protecting them from cosmic rays and solar radiation as well as from micro-meteorite strikes.
Building habitats from scratch would be more time-consuming and challenging, even when factoring in the potential need of reinforcing the cave walls to prevent a collapse, the team said.
Rocks and other material inside these caves — unaltered by the harsh surface conditions over the eons — also can help scientists better understand how the moon evolved, especially involving its volcanic activity.

Kollam (PTI): A teacher convicted in the sensational murder of Dr Vandana Das inside a hospital here was sentenced to life term on Saturday, and the prosecution said it will move an appeal seeking death penalty for the accused. The victim's family also batted for "maximum punishment".
Dr Das was brutally killed inside a taluk hospital in May 2023 by G Sandeep.
Kollam Additional District and Sessions judge P N Vinod sentenced Sandeep to a total of 30 years for various offences under the then Indian Penal Code (IPC) and said that after he serves that period, his life imprisonment for Das' murder will commence.
The court also imposed a fine of Rs 2.35 lakh on the convict.
Though the prosecution had sought death penalty for the accused during the arguments on sentence, the court was of the view that the case does not fall under the rarest-of-rare category to warrant the maximum punishment.
It was also of the view that there was a chance of the convict getting reformed as he told the court that the rest of his life would be one of repentance, the order on sentence said.
"At the same time, I agree with the stand of the prosecution to the effect that the sentence should commensurate with the gravity of the crime and the sentence should not only be reformative, but should also have a deterrent effect."
"In my view, the said objective can be achieved by directing that the term sentences that will be imposed will run consecutively and life sentence that has to be imposed will commence only after the expiration of terms sentences," the judge said.
After the verdict, special public prosecutor (SPP) Prathap G Padickal told reporters outside the court that he will recommend to the prosecution to file an appeal seeking enhancement of the life imprisonment to death penalty.
The victim's father said that the verdict has come as a relief for the family, but that he cannot authoritatively say whether his late daughter has got justice. He indicated his dissatisfaction with the punishment, saying that steps will be taken to seek its enhancement after discussions with the public prosecutor.
Dr Das' mother said that the family can only wish for the maximum punishment and it was up to the court to decide what sentence should be given. She said that the family will go in appeal, but declined to comment on whether her daughter got justice.
She tearfully said that she wants the convict to suffer the same pain that her daughter underwent "as he stabbed her 27 times".
The court on March 17 had convicted Sandeep for various offences under the IPC, including murder, destruction of evidence and wrongful restraint.
It had also held him guilty under the provisions of the Kerala Healthcare Service Persons and Healthcare Service Institutions (Prevention of violence and damage to property) Act 2012.
Sandeep was brought to the taluk hospital by the police for medical treatment during the small hours of May 10, 2023 and he went on a sudden attacking spree using a pair of surgical scissors kept in the room where his leg injury was being dressed.
A school teacher by profession, he had initially attacked the police officers and another person who had accompanied him to the hospital and then turned on the young Dr Das, who could not escape to safety.
She was stabbed several times and later succumbed to her injuries in a private hospital in Thiruvananthapuram where she was rushed following the attack.
Dr Das was a native of the Kaduthuruthy area of Kottayam district and the only child of her parents.
She was a house surgeon at Azeezia Medical College Hospital and was working at the Kottarakkara taluk hospital as part of her training.
Sandeep had called the emergency number 112, claiming that his life was in danger. When local police located him, he was standing close by his home, surrounded by local residents and his relatives, and had a wound on his leg following an alleged quarrel.
He was then taken to the hospital for dressing the wound.
