Jeff Bezos may have been beaten to space by rival Richard Branson, but the billionaire American businessman is poised to make history next week aboard what would be the world’s first unpiloted suborbital flight with an all-civilian crew.

Bezos, the former CEO of Amazon, is due to be part of a four-person crew for a planned 11-minute ride to the edge of space on Tuesday inside his company Blue Origin’s New Shepard spacecraft, another milestone in the nascent and potentially lucrative space tourism sector.

He is set to be joined by his brother and private equity executive Mark Bezos, trailblazing octogenarian woman aviator Wally Funk, and an as-yet-unidentified person who paid $28 million (roughly Rs. 210 crores) for a spot aboard the spacecraft, scheduled to launch from a West Texas site.

New Shepard is a 60-foot-tall (18.3-meters-tall) and fully autonomous rocket-and-capsule combo that cannot be piloted from inside the spacecraft. The crew is set to include only civilians and none of Blue Origin’s employees or staff astronauts, three people familiar with the company’s plans told Reuters.

Blue Origin’s astronauts include NASA space shuttle veteran Nicholas Patrick.

“To see the Earth from space, it changes you, it changes your relationship with this planet, with humanity,” Bezos said in a video last month discussing the flight.

There has never before been a fully autonomous suborbital or orbital flight with an all-civilian crew, Teal Group space industry analyst Marco Caceres said.

Branson, the British billionaire businessman, was aboard his company Virgin Galactic’s rocket plane for its pioneering suborbital flight from New Mexico on Sunday. The Virgin Galactic flight included two pilots, as well as the company’s chief astronaut instructor and its lead operations engineer.

New Shepard lifts off from a standing position on a launch pad, like traditional rocket launches. With Virgin Galactic, a rocket-powered spaceplane was dropped from a carrier plane in mid-air.

New Shepard, like Virgin Galactic’s flight, will not enter into orbit around Earth, but will take the passengers some 62 miles up (100km) before the capsule returns by parachute. Virgin Galactic’s flight reached 53 miles (86km) above Earth.

Billionaire businessman Elon Musk’s space transportation company SpaceX is planning an even-more-ambitious mission in September, sending an all-civilian crew for a several-day orbital flight aboard its Crew Dragon capsule.

‘Simple math’

Blue Origin’s flight is two decades in the making. Bezos founded the company in 2000. A pilotless craft was a financial strategy adopted by Blue Origin executives years ago.

“It’s simple math,” said one of the people familiar with the company’s thinking. “If you design a system so that you don’t need a pilot or a co-pilot you can have more paying customers.”

New Shepard can accommodate six people. Blue Origin and industry insiders had previously discussed company employees going up on the first flight.

A Blue Origin spokesperson confirmed the decision was made for four seats to offer an enhanced customer experience for the first flight.

The decision to skip over Blue Origin’s staff astronauts and technical experts has caused frustration for some company insiders who viewed the first crewed flight as a crucial opportunity to gather data and technical feedback for a program in its infancy, and to evaluate the experience for future paying customers, the sources said.

A seasoned astronaut would provide a calming presence for civilian crew members as New Shepard blasts off at speeds upwards of 2,200 miles (3,540km) per hour, the sources added.

The crew members will receive two days of training. Blue Origin has assigned two staff members, on the ground, to help the passengers strap in and to provide point-by-point instructions over headsets during the mission.

“It’s kind of like getting on a ride at an amusement park,” Caceres said. “You just trust that everything has been checked out, is in good working order … and you just sit back and enjoy the ride.”

Some industry sources have expressed concerns that passengers – overwhelmed by the experience or in a state of euphoria – could be rattled by routine noises, miss key instructions, pass out or injure themselves floating around the cabin, potentially dangerous scenarios a trained astronaut could respond to.

Funk, 82, was one of 13 women who passed the same rigorous testing as the Mercury Seven male astronauts in NASA’s 1960s space programme but were denied the chance to become astronauts because of their gender.

Proving the safety of space travel is important to developing what Swiss investment bank UBS estimates will be a $3 billion (roughly Rs. 22,350 crores) annual tourism market a decade from now.

“One of the main goals of the New Shepard mission is to demonstrate that going to suborbital space is perfectly safe for the average person,” Caceres said. “So there is a benefit to having as many average people on these flights as possible.”

2,300-Year-Old Celtic Helmet Found in Poland’s Łysa Góra Site!

Archaeologists in Poland have unearthed a remarkable find: a 2,300-year-old bronze helmet, along with other artifacts, marking the first evidence of Celtic settlement in northern Poland. This discovery, led by Bartłomiej Kaczyński from the State Archaeological Museum in Warsaw, indicates that Celts were present in the region to secure their amber supplies. Previously, Celts were known to have colonised southern Poland around 400 B.C., but evidence of their presence in the north was scarce until now.

Details of the Helmet

The helmet, crafted from thin bronze and styled in the Celtic “Berru” fashion, features a conical top and a distinctive nape, reflecting its association with Celtic elites, the State Archaeological Museum announced in a Facebook post. It was found at the Łysa Góra archaeological site near Chorzele, about 105 kilometres north of Warsaw. The discovery is significant as it represents the most northeastern site in Europe where Celts have been documented.

Other Artifacts Unearthed

In addition to the helmet, the excavation revealed over 300 ancient artifacts, including four iron axes and an iron sword, archaeologist Bartłomiej Kaczyński . These items suggest that the Celts may have introduced iron metallurgy to the area. The team also uncovered Celtic ornaments, brooches, and several tools not previously known in Poland, such as iron chisels, scythes, and scissors. This challenges the earlier belief that Celtic interactions in northern Poland were minimal.

Importance of the Site

The findings indicate that the Łysa Góra site was a crucial trading post on the “amber trail” leading from the Baltic Sea coast. Amber, highly prized in the Mediterranean world, was a key commodity for the Celts. The site’s location suggests it played a significant role in protecting and trading amber between different regions.

Overall, these discoveries shed light on the extent of Celtic influence and their strategic importance in ancient trade networks.

Strange Signal From Greenland Landslide Reveals Climate Change Effects

In September 2023, scientists monitoring seismic activities worldwide detected an unusual signal. This signal, distinct from the typical earthquake rumble, resonated as a continuous hum, maintaining a singular frequency. For nine consecutive days, this hum echoed across the globe, spanning from the Arctic to Antarctica, leaving researchers baffled. Initially classified as a “USO” — an unidentified seismic object — the source of the signal was eventually identified. A colossal landslide in Greenland‘s Dickson Fjord was responsible for the mysterious hum. The event involved a massive amount of rock and ice, enough to fill approximately 10,000 Olympic-sized swimming pools, plummeting into the fjord. This caused a mega-tsunami, with waves towering up to 200 metres, double the height of London’s iconic Big Ben.

The Landslide’s Source

The landslide was directly linked to the ongoing effects of climate change. Due to the thinning of a nearby glacier, the fjord’s stability had been compromised. The glacier had lost tens of metres in thickness over decades, leading to a weakened structure. When the mountain finally gave way, the sheer force of the collapse generated seismic waves that reverberated around the planet.

Implications of the Event

In their study published in Science, the research team noted that the signal was created by standing waves within the fjord caused by the rockslide. These findings underscore the cascading and hazardous feedback loops between the Earth’s ice, water, and land systems as the climate continues to warm.

As global temperatures rise, landslides, tsunamis, and similar events in polar regions could become more frequent.

Supercooling of Earth’s Inner Core May Finally Reveal its True Age

Supercooling of Earth's Inner Core May Finally Reveal its True Age

Earth‘s inner core, made of solid iron and nickel, lies over 5,100 kilometres below the surface. Despite its crucial role in shaping Earth’s conditions and generating its magnetic field, the core’s age has remained a mystery. Thanks to advancements in mineral physics, scientists are now closer to understanding how and when the core formed. The solid core is vital for maintaining Earth’s magnetic field, which shields us from harmful solar radiation, making the planet habitable for billions of years.

Inner Core’s Formation and Freezing Process

The inner core, which was once molten, solidifies as the Earth cools down. This cooling process causes the iron-rich liquid surrounding the core to freeze, expanding the inner core outwards, although the temperature at the core remains scorching, at over 5,000K (around 4,726°C). The freezing of iron releases lighter elements like oxygen and carbon, creating a buoyant liquid that rises into the outer core, producing electric currents. These currents drive the Earth’s magnetic field, which is responsible for phenomena like the northern lights.

Supercooling and the Core’s Age

Geophysicists use thermal models to study Earth’s magnetic history. These models have revealed that supercooling, where a liquid cools below its freezing point without solidifying, could explain the core’s formation. Recent studies suggest that iron at the core may need to be supercooled by up to 1,000K before freezing. However, this level of cooling implies that the core might be much younger, between 500 and 1,000 million years than previously thought. Current evidence suggests the core may have experienced less than 400K of supercooling.

The age of Earth’s inner core remains a topic of intense study, with scientists exploring the possibility that the core could be younger than estimated due to this supercooling phenomenon. Understanding this could reshape our knowledge of Earth’s magnetic history.
