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.”

Blue Origin New Glenn Set for Launch on January 10 from Cape Canaveral

The highly anticipated debut launch of Blue Origin’s New Glenn rocket has been scheduled for January 10, 2025. The heavy-lift rocket, designed for both commercial and government missions, will take off from Florida’s Cape Canaveral Space Force Station. A launch window of three hours, beginning at 1 a.m. EST, has been announced. The rocket’s inaugural flight marks a significant milestone for Blue Origin as the company aims to validate its capabilities and establish itself as a major player in the space industry.

New Glenn’s Mission and Capabilities

According to Blue Origin, as reported by space.com, the New Glenn rocket is a reusable, 320-foot-tall launch vehicle capable of carrying 50 tons (45 metric tons) to low Earth orbit (LEO). The NG-1 mission will test the company’s Blue Ring spacecraft platform, which is designed to support a variety of orbital payloads. This demonstration will include assessments of communication systems, in-space telemetry, and ground-based tracking capabilities. The payload will remain aboard the rocket’s second stage for a six-hour mission, as stated by Blue Origin.

Booster Recovery and Future Goals

The mission will also attempt a recovery of the rocket’s first stage booster, which will land on a ship stationed in the Atlantic Ocean, as per reports from space.com. The company’s senior vice president, Jarrett Jones, emphasised the importance of the flight, stating that rigorous preparations had been undertaken but that true insights could only be gained through actual launch experiences.

NG-1 is a critical step toward securing certification for U.S. national security missions. A successful outcome would bring Blue Origin closer to fulfilling these high-stakes contracts, further solidifying its position in the competitive aerospace sector.

This launch will serve as a proving ground for the New Glenn system, with valuable data expected to inform future missions and technology advancements.

Spiders Detect Smells Through Leg Hairs, Claims New Study

New research has revealed that spiders use specialised hairs on their legs to detect airborne scents, offering fresh insights into the sensory abilities of these arachnids. This discovery has resolved a long-standing question about how spiders, which lack antennae like insects, can identify odours such as pheromones. Male spiders were observed using olfactory hairs, known as wall-pore sensilla, to sense sex pheromones emitted by females. This mechanism underscores their ability to locate potential mates through chemical signals.

Olfactory Sensilla Identified

According to a study, published in the Proceedings of the National Academy of Sciences, the wall-pore sensilla were found on the upper legs of adult male wasp spiders (Argiope bruennichi). These microscopic structures are believed to be critical for detecting pheromones. High-resolution scanning electron microscopy revealed thousands of these sensilla, which were absent in females and juvenile males. This specific distribution supports their role in mate detection. Researchers emphasised to phys.org that these findings have mapped and identified the elusive sensilla, previously thought to be absent in spiders.

Response to Pheromones

Experiments demonstrated the sensitivity of these sensilla to pheromone compounds. Tiny amounts of the substance, such as 20 nanograms, elicited significant neuronal responses. The experiments involved exposing the sensilla to pheromone puffs, and responses were observed consistently across various leg pairs. The researchers concluded that spiders’ olfactory systems rival the sensitivity seen in insects, highlighting their advanced chemical detection capabilities.

Broader Implications

The study explored 19 other spider species and confirmed the presence of wall-pore sensilla in most male spiders, suggesting that this trait evolved multiple times. However, it was noted that some primitive species lack these structures. Future research is expected to investigate how female spiders detect smells, the types of chemicals relevant to their behaviours, and the evolutionary aspects of olfaction in spiders.

This breakthrough provides a foundation for understanding the sophisticated sensory mechanisms that govern spider behaviour.

PFAS Chemicals Harm Freshwater Turtles in Australia, New Research Finds

Exposure to per- and polyfluoroalkyl substances (PFAS), often termed “forever chemicals,” is raising concerns over its impact on wildlife health. Recent research has uncovered significant health problems in freshwater turtles in Australia exposed to PFAS. These issues are not limited to adult turtles but extend to their hatchlings. PFAS, widely known for their persistence in the environment, have been found accumulating in the organs of these reptiles, potentially impacting their long-term survival and reproduction.

Study Reveals PFAS Impacts on Australian Turtles

According to a study published in Science of the Total Environment, researchers, led by David Beale, an environmental biochemist at the Commonwealth Scientific and Industrial Research Organisation (CSIRO), examined freshwater turtles (Emydura macquarii) from three locations in Queensland. These sites varied in PFAS contamination levels, with some showing high concentrations and others barely detectable. The study found that PFAS exposure disrupted metabolic functions in turtles and led to bioaccumulation in vital organs, including the ovaries, liver, kidneys, and heart.

In statements provided to Science News, Beale explained that hatchlings from lab-incubated eggs, derived from PFAS-exposed turtles, showed deformities such as scale abnormalities. He noted that contamination was transferred to offspring via fats and nutrients, raising alarms over generational health impacts.

Concerns Over Declining Juvenile Populations

Reports indicate that juveniles are missing in PFAS-contaminated sites. Beale suggested this could be linked to deformities making them vulnerable to predators or early mortality due to health issues. Differences in egg size and number were also observed, though direct connections to PFAS remain unconfirmed.

Experts Call for Urgent Action

Jean-Luc Cartron, a biologist at the University of New Mexico, expressed concern in his statement to Science News over these findings, emphasising the urgency to address ecological toxicity. He warned that delays in action could result in the loss of entire generations of wildlife.

The research team plans to expand studies to other species and regions, including crocodiles, frogs, and cane toads, to better understand the widespread impact of PFAS on wildlife.
