The lamps hanging on the walls project a dim light while an elevator-like cage glides down the mine's shaft. The cage can accommodate only ten visitors in each tour.

Over the past 20 years, Röhrigschacht - an ancient copper mine based in the Harz Mountains (southern Germany) that has been turned into a museum - has provided underground five-hour tours, the German news agency reported.

At 283 meters underground, tour guide Thomas Wäsche said: "We will use a boat on this trip." Each visitor had to wear a lamp helmet and water repellent pants.

The work of miners was completely different 130 years ago. They used to load copper pieces on flat carriages tied to the legs of 14-year-old beginners, who pulled them through the mine's openings.

"Those young boys had to drag these heavy carriages to loading points 10 to15 times a day," said Wäsche. At the time, the workers' torches were the only lightning source in the mine.

During the tour, the helmets kept hitting the ceiling and the water ran abundantly. The arid walls are covered with unique colors ranging from strong brown tones to white, green, turquoise, blue and black.

Since the mine was abandoned in 1885, the running water has broken down the limestone rocks.

The group now stands in front of an inclined pathway known as "Bremsberg".

"The carriages loaded with copper took this pathway down to the main entrance, while their weight pulled the empty carriages up to the facing route. This was a vehicle-free transport mean," explained Wäsche.

In the next round, the visitors stood in the water, and fortunately, the water repellent pants were useful. Then, the group took four boats that ran along the narrow waterway with the help of pedals and a light stream.

After over 350 meters, as the water pathway narrowed down, the group left the boats to the water.

"If someone believes he can't make it, he can wait here until we return," said the guide.

However, no one wanted to wait. In this part, Wäsche provided the visitors with knee pads. The path was only 60 centimeters high, and everybody had to crawl towards the opening while their backs touched the ceiling. Finally, with the end of the crawling journey, the visitors sat in an empty space for some rest.

More than half a century ago, a Hungarian architect, sculptor and professor invented what would become one of the world's most popular and beloved puzzles whose appeal has spanned generations: the colorful, mind-bending, six-sided Rubik's Cube.

Now, after selling more than half a billion units and becoming a worldwide cultural touchstone, production of the cube is returning to Hungary, where its inventor, Ernő Rubik, first conceived of the iconic object that bears his name.

Hungary “is the home of the cube. The cube was born here,” Rubik, 82, said on Tuesday at the opening of a new, fully automated Rubik's Cube production line in the Hungarian city of Jászberény.

The journey of the Rubik's Cube began in 1974, when Rubik was teaching design at the Academy of Applied Arts and Design in Budapest. Seeking to create a three-dimensional object that was “infinite,” he said, he completed a prototype — then made of wood — of a cube that could rotate on multiple axes and was made up of 27 blocks.

Recognizing its consumer value, Rubik soon began producing more of the puzzles. Beginning in 1977, an initial 5,000 units of what was then called the “Magic Cube” were sold at specialty shops in the Hungarian capital.

The invention — or what Rubik prefers to describe as a “discovery” — gained popularity, and after having difficulties procuring materials for the cubes in then-socialist Hungary, he realized: “We were not prepared for that size of production ... We can’t fulfill the needs of the market worldwide.”

The cube was licensed to a British and then a US toy company, and its production was moved abroad. By the early 1980s, its popularity had exploded in what Rubik called “the first big wave,” in which he said 200 million units were sold between 1980 and 1983.

While sales of the cube dipped after its initial success, it still attracts plenty of users eager to try their hand at solving the puzzle. Millions are sold every year.

At the new production line in Hungary, a series of robotic arms assembles the cubes and tests them for functionality and durability — a level of automation Rubik said was “very different” than in the early days when the cubes were assembled by hand.

The new line in Jászberény plans to produce 1 million cubes annually.

Steve Radewych, a senior vice president with Canadian toy company Spin Master, which owns the Rubik's Cube trademark, said at Tuesday's opening that the theme of the day was: “Back to its roots: The cube comes home.”

“Ernő, your discovery is more than a toy,” Radewych told Rubik. “It's a global social phenomenon.”

Radewych noted the “incredible staying power” of the Rubik's Cube, and the fact that the puzzle continues to hold the fascination of young people even today.

“The cube represents an intellectual journey, a symbol of intelligence, problem-solving and cognitive discipline,” he added, which “has brought joy — and frustration — to many generations.”

The cube has enjoyed another surge in popularity in recent years as global competitions have proliferated, measuring who can solve the puzzle the fastest.

The current record, set only last month in China by nine-year-old Xuanyi Geng, is 2.51 seconds, according to the World Cube Association, which organizes and certifies competitions across the world.

Rubik, who does not consider himself a speed competitor, said that for him, the cube represents a “transformable sculpture,” the place where art and engineering meet and users can manipulate and change the cube in nearly endless variations.

“If you are doing something, creating something, you have the chance to do something that is meaningful — that’s one part — and beautiful,” he said.


SpaceX Starship Test to Attempt First-Ever Spaceship ‘Catch'

Elon Musk's SpaceX was poised Friday to carry out its latest test of the world's biggest and most powerful rocket, the Starship, with plans for a groundbreaking "catch" of the spaceship following a day in orbit.

A successful capture of the Starship upper stage would mark a significant milestone in the space industry's decades-long pursuit of fully reusable spacecraft that can drastically reduce mission costs and make frequent travel possible.

"If successful, this will mark the first full recovery of an orbital launch system and a breakthrough moment in making Starship a reliable, rapidly reusable rocket," SpaceX said.

For the 15th Starship test flight Friday, SpaceX aims to recover both stages of the massive 124-meter (407-foot) launch vehicle.

The company has caught the booster, dubbed Super Heavy, on three previous occasions, with the first stage descending vertically back to the launch site shortly after blastoff and nestling into mechanical "chopstick" arms.

It will now attempt to do the same with the spaceship. Some versions of the vessel are designed to launch internet satellites and data centers into orbit, while others will be made to ferry people to the Moon and Mars.

A spacecraft that can be fully reused is the "Holy Grail" of the space industry, said Clayton Swope, an aerospace expert at the Center for Strategic and International Studies.

"No one's really been able to do that so far," he said. "People have been trying to do that since the (NASA) space shuttle. But the space shuttle ended up being kind of a compromise because a lot of the vehicle wasn't reusable."

Reusing the Starship spacecraft would require the vessel to withstand the extreme heat of reentering Earth's atmosphere and then return to service without extensive refurbishment.

- Refueling challenge -

Musk, the world's richest person, has already revolutionized the space sector with the partially reusable Falcon rockets, which are regularly employed to launch satellites and carry astronauts to the International Space Station.

The Starship project, however, has been plagued by years-long delays as SpaceX grapples with novel engineering challenges -- even as NASA is counting on the spaceship to serve as a lunar lander for its Artemis program.

Other technical challenges include transferring fuel to Starship in orbit -- a requirement for any journey to the Moon or Mars.

Following SpaceX's high-profile stock market debut in June, the company carried out the first orbital flight of Starship in September, though the mission was cut short due to an engine issue.

It is also investing heavily in additional launch sites for its mega-rocket in Louisiana and Florida.

- Complex capture -

Friday's launch is scheduled to take place at SpaceX's "Starbase" in southern Texas at 4:45 pm (2245 GMT).

Following liftoff and the mid-air separation of the two stages, SpaceX plans to bring Super Heavy back to Earth six and a half minutes later, catching it at the launch site on the Gulf of Mexico coastline.

The spaceship will continue to reach Earth's orbit, where it will deploy 26 satellites into Musk's Starlink satellite internet constellation that has become a major revenue stream for SpaceX.

It will then circle the planet 14 times, before returning 22 hours later and -- SpaceX hopes -- descending safely into the chopstick arms.

This capture attempt is more complex than that of the booster, as the spaceship will be descending much faster and from a much greater altitude.

SpaceX has said it would proceed with these maneuvers only if conditions are optimal, and in the past has made last-minute changes to test flights under Musk's "fail fast" strategy of learning through crashes, explosions and other mishaps.

As of late Thursday, the US Federal Aviation Administration had not yet given its final approval for the test flight.

India's capital Delhi overtook Lahore in Pakistan to become the world's most polluted city on Friday, with air quality reaching hazardous levels and visibility dropping as smog blanketed the city of 20 million people.

Air quality index (AQI) in Delhi was "hazardous" at 334, making ‌it the ‌most polluted global major ‌city, ⁠according to Swiss group ⁠IQAir, which measures air quality levels based on the concentration of toxins.

An AQI reading up to 50 is considered good with little or no ⁠health risk.

India's official ‌Central Pollution ‌Control Board pegged the AQI higher at ‌403 and rated it "severe".

The ‌Swiss and Indian readings vary due to the different AQI scales and methodologies used to calculate and ‌classify air pollution levels.

Cars and motorcycles emerged from dense ⁠smog, ⁠which also appeared to obscure streetlights on the city's main roads, videos from news agency ANI showed.

Pollution is a seasonal problem in many parts of northern India and neighboring Pakistan, as the cold, heavy air of winter traps vehicle emissions, construction dust and smoke from agricultural burning.
