During NASA’s Apollo program in the late 1960s and 1970s, humans landed on the moon using computers with far less processing power than today’s smartphones.
Still, 50 years later, landing on the moon is still no easy feat.
Several notable missions over the past few years have proven that point. Israeli Beresheet spacecraft It crashed into an ancient lunar volcanic field called the Sea of Silence in 2019, and last year it crashed into Russia’s Luna 25 mission and a commercial. Japanese lander “Hakuto-R” Both crashed into the moon’s surface. (But India celebrated becoming the fourth country To land a spaceship on the moon. )
Successful or not, the effort is part of a new space race centered on advancing lunar exploration. Several projects are expected to head to the moon for soft landings this year.
The first commercial mission outside the United States did not go as planned.
From Astrobotic
Astrobotic Technology on Monday shared the first images of the Peregrine lunar lander in space. The lander suffered a “significant” loss of propellant due to a fuel leak after liftoff.
Astrobotic Technology, the Pittsburgh-based company that developed the first U.S. lunar lander in 50 years, is under a $108 million contract with NASA. Abandoned plans to attempt a soft landing For Peregrine Mission 1 on the Moon.
The spacecraft successfully launched on Monday atop a new Vulcan Centaur rocket developed by United Launch Alliance, which was on its maiden flight. Shortly thereafter, Peregrine suffered a “significant” loss of propellant due to a fuel leak, making the controlled moon landing originally scheduled for February 23 impossible, Astrobotic said. .
NASA had hoped that Peregrine 1 would be an early success in the Commercial Lunar Module Service Program, which aims to reduce the cost of building lunar landers — especially for the space agency. . Returning astronauts to the moon faces long delays.
New research based on DNA recovered from ancient bones and teeth offers clues to why Scandinavians are among the most susceptible to the debilitating autoimmune disease multiple sclerosis. It was done.
A comparison of more than 1,000 ancient genomes collated as part of a new database finds a link between multiple sclerosis risk and a common ancestor with a Bronze Age nomadic group known as the Yamnaya.
Researchers believe that these nomadic tribes, originally from the steppes of central Europe, moved west and introduced genetic mutations that had evolved to protect them from infectious pathogens carried by livestock in the past. influence modern diseases In a completely different way.

Many of the caves containing Gigantopithecus brachy fossils are located in the unique karst landscape of China’s Guangxi Zhuang Autonomous Region.
Why did the largest ape death in history occur?
New research published this week sheds further light on the mystery of why Gigantopithecus brachyi, a species of primate sometimes referred to as the real King Kong due to its nearly 10 feet (3 meters) height, disappeared. I guessed it.
Paleontologists analyze and date fossils and sediments in the caves where animal remains were found, and learn how the animals’ diets and the environments they lived in changed over time. Understood and narrowed down the results. Possible period and reason for species extinction.
Gigantopithecus was discovered in 1935 after paleontologist GHR von Königswald discovered a large tooth sold as “dragon bone” in a traditional medicine store in Hong Kong.
The first fast radio bursts (FRBs) were discovered in 2007, and since then scientists have detected hundreds of powerful, millisecond bursts of radio waves emanating from distant points in space.
Much remains unknown about these quick cosmic flashes and their origins.But now astronomers have tracked down One of the most powerful and far-reaching high-speed radio bursts A rare ‘clump-like’ group of galaxies has been detected, home to an unusual universe.
This unexpected discovery could provide insight into the causes of mysterious radio bursts that have puzzled scientists for years.

The oldest known fossil skin is at least 130 million years older than the oldest known example. The pebble-like surface resembles crocodile scales.
The world’s oldest known fossilized skin belonged to a type of reptile that lived before dinosaurs appeared on Earth.
The skin fragment, which has a pebble-like surface resembling crocodile scales, is more than 289 million years old, making it the oldest skin known to date, according to new research published Thursday. It is said to be at least 130 million years older than the fossils of
Skin and other types of soft tissue decay much more easily than bone, so they rarely fossilize.
However, researchers at the University of Toronto Mississauga believe the sample was preserved for several reasons: unique features One such site is the Richards Spur Cave System in Oklahoma. Many of the earliest examples of early land animals have been found here.
