Decades after burnishing his reputation as a wealthy daredevil mogul in a series of boating and hot-air balloon expeditions, Richard Branson is poised to promote his burgeoning astro-tourism venture by launching himself to the final frontier.

Branson’s Virgin Galactic is due on Sunday to send the company’s passenger rocket plane, the VSS Unity, on its first fully crewed test flight to the edge of space, with the British billionaire founder among the six individuals strapping in for the ride.

The gleaming white spaceplane will be borne by a twin-fuselage carrier jet dubbed VMS Eve (named for Branson’s mother) to an altitude of 50,000 feet, where Unity will be released and soar by rocket power in an almost vertical climb through the outer fringe of Earth’s atmosphere.

At the apex of its flight some 55 miles (89km) above the New Mexico desert, the crew will experience a few minutes of weightlessness before making a gliding descent back to Earth.

If all goes according to plan, the flight will last about 90 minutes and end where it began – on a runway at Spaceport America near the aptly named town of Truth or Consequences.

Virgin’s Unity 22 mission marks the 22nd test flight of the spacecraft, and the company’s fourth crewed mission beyond Earth’s atmosphere.

But it will be the first to carry a full complement of space travelers – two pilots and four “mission specialists,” Branson among them.

Milestone and publicity

Although the mission is seen as a potential milestone in helping transform citizen rocket travel into a mainstream commercial venture, spaceflight remains an inherently hazardous endeavor.

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.

If successful, Sunday’s flight will also give Branson bragging rights to besting rival Jeff Bezos and his space company, Blue Origin, in what has been popularised as a “billionaire space race.” Bezos, founder of online retail giant Amazon.com, is slated to fly aboard Blue Origin’s suborbital rocketship, the New Shepard, later this month.

Branson’s official job on his flight is to “evaluate the private astronaut experience,” and his observations will be used to “enhance the journey for all future astronaut customers,” according to Virgin’s press materials.

But Marco Caceres, a senior space analyst for the Virginia-based consulting firm Teal Group, said the Branson and Bezos ride-alongs were each “a bit of a publicity stunt.”

“If they succeed, their ventures will be taken more seriously,” Caceres said. “There’s plenty of multimillionaires in the world that would like to go up on an adventure, so long as they see it as relatively safe.”

Virgin Galactic and Blue Origin, along with fellow billionaire entrepreneur Elon Musk’s SpaceX, are competing head-to-head in the emerging business of space tourism, though Musk has a big head start.

SpaceX, which plans to send its first all-civilian crew (without Musk) into orbit in September, has already launched numerous cargo payloads and astronauts to the International Space Station.

Branson, 70, insists there is plenty of demand from wealthy would-be citizen astronauts to go around, and that he had no intention of trying to upstage Bezos.

‘Not a race’

“It’s honestly not a race,” Branson told Reuters in an interview earlier this week. “If it’s a race, it’s a race to produce wonderful spaceships that can make many more people be able to access space. And I think that’s both of our aims.”

The spaceplane’s two pilots, Dave Mackay and Michael Masucci, will control the ignition and shutoff of the ship’s rocket engine, and activate the vehicle’s “feathered” tail maneuver for re-entry.

The three other mission specialists are 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.

The Virgin brand, including Branson’s airline and former record label, has long been associated with exploits of derring-do by its flamboyant founder. Branson set a new record for the fastest boat crossing of the Atlantic in 1986, a year after his initial attempt ended with a Royal Air Force helicopter rescue when his vessel capsized.

In 1987 he made a record-breaking Atlantic crossing by hot-air balloon, though again he had to be rescued from the sea. He went on to break at least two other air-balloon speed records but failed to complete any of three bids to circumnavigate the globe by balloon.

As for Sunday’s flight, Branson said this week that he is excited, “and I really don’t think there’s anything there to be scared about.”

Assuming the mission goes well, Virgin has said it plans two further test flights of the spaceplane before beginning commercial service next year.

The company has said it has received more than 600 flight reservations, priced at around $250,000 (roughly Rs. 1.9 crores) per ticket, but hopes eventually to slash the cost of each seat to $40,000 (roughly Rs. 29.8 lakhs).

Photosynthetic Machinery from Plants Operates Within Hamster Cells

A breakthrough experiment has showcased the ability of chloroplasts, essential for photosynthesis in plants, to function inside animal cells. Red algal chloroplasts were introduced into cells derived from Chinese hamster ovaries (Cricetulus griseus), where they remained active for 48 hours, converting light into energy. This achievement represents a step forward in efforts to recreate the symbiotic processes seen in nature, offering potential applications in scientific engineering. The project aims to harness photosynthesis in non-plant organisms for diverse purposes.

Chloroplast Integration into Animal Cells

According to the study published in Proceedings of the Japan Academy, Series B, the research was led by Sachihiro Matsunaga, a biologist at the University of Tokyo. His team selected resilient chloroplasts from red algae capable of thriving in extreme conditions, such as volcanic hot springs. These organelles were isolated using a centrifuge and a controlled process that avoided direct damage to animal cells. Instead of piercing cell membranes, the technique involved modifying the culture medium to prompt animal cells to engulf the chloroplasts naturally.

Functionality and Challenges

A Scientific American report confirm that the transplanted chloroplasts demonstrated electron transport—a vital component of photosynthesis—for two days before disintegrating. Past attempts had only succeeded in maintaining chloroplast function for a few hours. However, challenges persist, as chloroplasts require proteins that animal cells cannot naturally produce. Werner Kühlbrandt, a structural biologist at the Max Planck Institute of Biophysics, highlighted the absence of genes needed for protein synthesis and transport, which accelerates chloroplast degradation.

Future Applications

Plans to incorporate photosynthesis-maintaining genes into animal cells are underway, as stated by Matsunaga. This research aims to create photosynthesizing materials for applications such as carbon dioxide capture or oxygen-rich organoid growth. Experts like Jef D. Boeke, a cell biologist at NYU Grossman School of Medicine, believe these advancements may pave the way for innovative uses in biotechnology. Solar-powered humans, however, remain speculative, requiring vastly more surface area than human bodies can provide.

SpaceX’s Starship to Launch its 7th Flight Test on January 13 with New Payloads

SpaceX is set to launch its Starship rocket for its seventh flight test on January 13, with liftoff planned at 5 p.m. EST from the Starbase facility in South Texas. The 400-foot-tall reusable rocket has been designed to support missions to the Moon and Mars. Reportedly, for the first time, the mission aims to deploy payloads in space, marking a significant milestone in the rocket’s testing phase. The launch webcast will begin approximately 35 minutes before the scheduled liftoff.

Mission Objectives and Payload Details

According to report from space.com, this test will feature the deployment of ten mock satellites. These are said to mimic the size and weight of next-generation Starlink satellites, as part of a preparatory exercise for future satellite deployment missions. The satellites, as noted, will follow the same suborbital trajectory as the rocket, with splashdown targeted in the Indian Ocean. Starship’s 50-metre upper stage, referred to as “Ship,” is also expected to return via a controlled splashdown in the Indian Ocean, consistent with previous test flights.

Reusability and Booster Retrieval

As reported by space.com, the Super Heavy booster used in this mission will include a previously flown Raptor engine, marking the first reuse of hardware in a Starship flight. Efforts will also be made to repeat the catch of the Super Heavy booster using Starbase’s launch tower, a manoeuvre that was successfully executed in October 2024 but faced challenges in November’s test due to communication issues.

Upcoming Launch Schedule

The test coincides with an active period in space exploration. Blue Origin’s New Glenn rocket is preparing for its debut on January 10, and a SpaceX Falcon 9 mission carrying private moon landers is slated for January 15. These developments underscore the rapid advancements being made in the commercial space sector.

Drone mapping reveals ancient settlement in the Caucasus Mountains

A groundbreaking discovery has been made in the Caucasus Mountains where an ancient Bronze Age settlement, Dmanisis Gora, has been mapped using drone technology. This site, believed to be over 3,000 years old, reveals new insights into the evolution of large-scale settlements during the Late Bronze Age and Early Iron Age. Spanning an area far larger than initially expected, the research offers a fresh perspective on ancient urbanism and interactions between sedentary and mobile communities.

Drone Mapping Reveals Extensive Settlement

As reported by Science Daily, the project led by Dr. Nathaniel Erb-Satullo, Senior Lecturer in Architectural Science at Cranfield Forensic Institute and Dimitri Jachvliani, co-director at the Georgian National Museum, employed drone technology to create high-resolution models of the site. The drone, equipped with advanced imaging tools, captured nearly 11,000 photographs, which were later used to generate detailed maps of the settlement. This method allowed the identification of fortification walls, graves and other structural remnants spread across a vast area.

The site, originally thought to be much smaller, was found to include a 1-kilometre-long defensive wall protecting an outer settlement. This finding significantly alters the understanding of the region’s settlement patterns, which were influenced by interactions with pastoral communities and seasonal population dynamics.

Integrating Modern and Historical Data

To further analyse the settlement, drone-generated images were compared with declassified satellite imagery from the Cold War era. This comparison highlighted changes in the landscape over decades, distinguishing ancient features from those impacted by modern agricultural activities. Geographic Information System (GIS) software was employed to integrate and analyse the diverse datasets, revealing patterns in the site’s expansion and usage over time.

Dr. Erb-Satullo noted to Science Daily, that these findings offer invaluable data on population density, agricultural practices and the broader socio-economic landscape of ancient societies. Continued excavations have uncovered artefacts such as pottery shards and animal remains, shedding more light on the lives of the people who inhabited Dmanisis Gora. This research underscores the potential of drone technology in unearthing and documenting historical sites on an unprecedented scale
