British billionaire Richard Branson on Sunday soared more than 50 miles above the New Mexico desert aboard his Virgin Galactic rocket plane and safely returned in the vehicle’s first fully crewed test flight to space, a symbolic milestone for a venture he started 17 years ago.

Branson, one of six Virgin Galactic employees strapped in for the ride, touted the mission as a precursor to a new era of space tourism, with the company he founded in 2004 poised to begin commercial operations next year.

“We’re here to make space more accessible to all,” an exuberant Branson, 70, said shortly after embracing his grandchildren following the flight. “Welcome to the dawn of a new space age.”

The success of the flight also gave the flamboyant entrepreneur bragging rights in a highly publicised rivalry with fellow billionaire Jeff Bezos, the Amazon online retail mogul who had hoped to fly into space first aboard his own space company’s rocket.

“Congratulations on the flight,” Bezos said on Instagram. “Can’t wait to join the club!”

Space industry executives, future customers and other well-wishers were on hand for a festive gathering to witness the launch, which was livestreamed in a presentation hosted by late-night television comedian Stephen Colbert. Joining the reception was another billionaire space industry pioneer, Elon Musk, who is also founder of electric carmaker Tesla.

Grammy-nominated R&B singer Khalid performed his forthcoming single “New Normal” after the flight.

The gleaming white spaceplane was carried aloft attached to the underside of the dual-fuselage jet VMS Eve (named for Branson’s late mother) from Spaceport America, a state-owned facility near the aptly named town of Truth or Consequences. Virgin Galactic leases a large section of the facility.

Reaching its high-altitude launch point at about 46,000 feet, the VSS Unity passenger rocket plane was released from the mothership and fell away as the crew ignited its rocket, sending it streaking straight upward at supersonic speed to the blackness of space some 53 miles (86 km) high.

The spaceplane’s contrail was clearly visible from the ground as it soared through the upper atmosphere, to the cheers of the crowd below.

At the apex of the climb with the rocket shut down, the crew then experienced a few minutes of microgravity, before the spaceplane shifted into re-entry mode, and began a gliding descent to a runway back at the spaceport. The entire flight lasted about an hour.

“I was once a child with a dream looking up to the stars. Now I’m an adult in a spaceship looking down to our beautiful Earth,” Branson said in a video from space.

Back at a celebration with supporters from a stage outside Virgin Galactic’s Gateway to Space complex at the spaceport, he and crewmates doused one another with champagne.

Retired Canadian astronaut Chris Hadfield pinned Virgin-produced astronaut wings onto the blue flight suits worn by Branson and his team. Official wing pins from the Federal Aviation Administration will be presented later, a company spokesman said.

High-cost tickets

Virgin Galactic has said it plans at least two further test flights of the spaceplane in the months ahead before beginning regular commercial operation in 2022. One of those flights will carry four Italian astronauts-in-training, according to company CEO Michael Colglazier.

He said 600 wealthy would-be citizen astronauts have also booked reservations, priced at around $250,000 (roughly Rs. 1.86 crores) per ticket for the exhilaration of supersonic flight, weightlessness, and the spectacle of spaceflight.

Branson has said he aims ultimately to lower the price to around $40,000 (roughly Rs. 29.7 lakhs) per seat as the company ramps up service, achieving greater economies of scale. Colglazier said he envisions eventually building a large enough fleet to accommodate roughly 400 flights annually at the spaceport.

The Swiss-based investment bank UBS has estimated the potential value of the space tourism market reaching $3 billion (roughly Rs. 22,340 crores) annually by 2030.

Proving rocket travel safe for the public is key.

An earlier prototype of the Virgin Galactic rocket plane crashed during a test flight over California’s Mojave Desert in 2014, killing one pilot and seriously injuring another.

Space race

Branson’s participation in Sunday’s flight, announced just over a week ago, typified his persona as the daredevil executive whose various Virgin brands – from airlines to music companies – have long been associated with his ocean-crossing exploits in sailboats and hot-air balloons.

His ride-along also upstaged rival astro-tourism venture Blue Origin and its founder, Bezos, in what has been popularised as the “billionaire space race.” Bezos has been planning to fly aboard his own suborbital rocketship, the New Shepard, later this month.

Branson has insisted he and Bezos are friendly rivals and were not racing to beat one another into space.

“We wish Jeff the absolute best and that he will get up and enjoy his flight,” Branson said at a post-flight press conference.

Blue Origin, however, has disparaged Virgin Galactic as falling short of a true spaceflight experience, saying that unlike Unity, Bezos’s New Shepard tops the 62-mile-high-mark (100 km), called the Kármán line, set by an international aeronautics body as defining the boundary between Earth’s atmosphere and space.

“New Shepard was designed to fly above the Kármán line so none of our astronauts have an asterisk next to their name,” Blue Origin said in a series of Twitter posts on Friday.

However, US space agency NASA and the US Air Force both define an astronaut as anyone who has flown higher than 50 miles (80km).

A third player in the space tourism sector, Musk’s SpaceX, plans to send its first all-civilian crew (without Musk) into orbit in September, after having already launched numerous cargo payloads and astronauts to the International Space Station for NASA.

The spaceplane’s two pilots were Dave Mackay and Michael Masucci. The three other mission specialists were Beth Moses, the company’s chief astronaut instructor; Virgin Galactic’s lead operations engineer Colin Bennett; and Sirisha Bandla, a research operations and government affairs vice president.

All recounted afterward being mesmerised by the view through Unity’s windows. Mackay described the immense blackness of space against the brightness of Earth’s surface, “separated by the beautiful blue atmosphere, which is very complex and very thin.”

“Cameras don’t do it justice,” he told reporters. “You have to see it with your own eyes.”

Ancient Roman Silver Coins As Old As 2,000 Years Unearthed By Researchers

A significant discovery of ancient silver coins has been made on the Mediterranean island of Pantelleria, located between Sicily and Tunisia. Archaeologists from the University of Tübingen, Germany, unearthed 27 Roman silver coins, known as “denarii,” dating back more than 2,000 years. The coins were found hidden in a hole in the wall during excavations at the Acropolis of Santa Teresa and San Marco. Some of these coins feature a human head profile, which remains unidentified.

Pirate Attack Theory

It is believed that the coins were hidden during one of the many pirate raids that plagued the region around 94 to 74 B.C., a period when the Roman Republic ruled. The discovery was made after earth from the site slipped following rainy weather, revealing part of the stash. The rest of the coins were found under a boulder. According to archaeologist Thomas Schäfer, the coins may have been concealed by locals during a pirate attack.

Pirates frequently raided coastal areas across the eastern Mediterranean until the Roman general Gnaeus Pompeius Magnus, known as Pompey the Great, defeated them in 67 B.C.

Roman Ruins and Previous Discoveries

The discovery of these coins occurred near an earlier find – the heads of three Roman statues. These marble heads included portrayals of Julius Caesar, Emperor Titus (who ruled from A.D. 79 to 81), and a woman who could be Agrippina the Elder, the granddaughter of Augustus, or Antonia the Younger, daughter of Mark Antony.

The archaeological site, once a Roman settlement known as Cossyra or Cossura, remains untouched by looters and features an assembly area known as a “comitium.” Only five such locations have been found in Italy, making this a significant and well-preserved find.

Great White Sharks Gather in This Mysterious Spot Every Year

Great White Sharks Gather in This Mysterious Spot Every Year

The White Shark Café, located in the Pacific Ocean between Baja California and Hawaii, is a mysterious region where great white sharks gather every winter and spring. This area, once thought to be an ocean desert, has puzzled scientists for years. Great white sharks, typically found off the coast of California, make a long journey to this remote location. Barbara Block, a marine sciences professor at Stanford University’s Hopkins Marine Station, named the area while studying the migration of these sharks using electronic tags between 1999 and 2000.

The Enigmatic Migration

Block’s research revealed that four out of six tagged sharks swam southwest, staying in this unexplored ocean patch the size of Colorado. These sharks also engaged in deep dives, some reaching depths of 1,500 feet, sparking curiosity among scientists. Why would these sharks leave their abundant hunting grounds in California to travel to what was once considered a barren part of the ocean?

A Lively Ocean Oasis

In 2018, Block and her team embarked on a mission to uncover the mystery behind the White Shark Café. They tagged 20 sharks and retrieved data from 10, revealing surprising findings. The Café, once thought to be desolate, was brimming with life.

Deep-sea fish, squids, and microscopic algae populated the area, suggesting it could be a vital food source for the sharks. But the study suggested that the food options in the open ocean were not more than the ones they could have found in their familiar hunting grounds, which leads to the speculation that the White Shark Café might have significance for mating practices.

Mysteries of Shark Diving Patterns

However, the question remains: why do sharks seek this food in the open ocean? Observing the sharks’ diving patterns, researchers noted that males increased their deep dives in April, leading to speculation about potential mating behaviours. Still, why males dive more than females remains unclear, leaving scientists like Block and her team searching for answers.

Placebo Effect Link Found With Previously Unassociated Parts of the Brain

Placebo Effect Link Found With Previously Unassociated Parts of the Brain

Patients suffering from chronic pain have limited treatment options, often relying on medications like opioids that come with harmful side effects and high addiction risks. A new study in mice, published in Current Biology journal, suggests a new way to use the placebo effect for treating chronic pain. By activating specific neurons in the brain linked to pain relief, researchers managed to create an environment where mice associated pain relief with their surroundings, providing a sustained placebo effect.

Study by Fan Wang’s Team

Fan Wang, a neuroscientist at the Massachusetts Institute of Technology, led this research. Wang and her team explored how neurons in the central amygdala could be “reverse-engineered” to mimic the placebo effect, according to a Science.org report. They conditioned mice, previously affected by chemotherapy-induced chronic pain, to link a particular environment with pain relief. Even when the neural stimulation was removed, the mice continued to display pain relief, showing reduced pain-related behaviours.

The Role of Pain-Suppressing Neurons

This placebo effect was achieved without reactivating the pain-suppressing neurons, indicating a separate brain mechanism driving this response. Researchers discovered that the placebo effect also occurred, though weaker, when the mice were given morphine instead of neural stimulation.

Potential Implications for Human Treatment

Fabrizio Benedetti, a placebo expert from the University of Turin Medical School, believes this study supports the idea that placebos and drugs might share common mechanisms. While the placebo effect in humans involves complex factors like social interaction, these animal models could help deepen our understanding of pain management.

Dr. Benedict Alter of the University of Pittsburgh notes that, although there is a long way to go before this research applies to human patients, these findings hold significant potential for drug-free treatments.
