SpaceX plans to announce two new space tourists slated to fly on the Starship rocket: Dennis Tito, the world’s first-ever space tourist in 2001, and his wife, Akiko. 

The couple paid an undisclosed amount to fly around the moon on Starship once the vehicle is complete. They will travel with 10 other undisclosed passengers on a roughly week-long journey. The trip doesn’t include a landing on the lunar surface and it’s unclear if the other passengers have been chosen yet.

It may be a while before the mission gets underway and there’s still no target date. It’s scheduled to be Starship‘s fourth passenger mission, conducted after SpaceX uses the vehicle to land astronauts on the moon for NASA and following trips by other customers who have purchased rides in the vessel.   

Then there’s the fact that Starship has yet to travel to space. SpaceX still needs to send an uncrewed version of the vehicle to orbit, which Chief Executive Officer Elon Musk said could occur as early as November. The company must also show it can refuel Starship while in space so that it can reach the moon’s vicinity, and it needs the necessary life-support systems and other hardware to keep humans alive.

“I know this rocket is going to be tested backwards and forwards; there’ll be hundreds of flights before we’re flying,” Tito said in an interview with Bloomberg. “We’re not going to fly next year. It’s going to be a wait.”

After a brief stint working as a scientist at NASA’s Jet Propulsion Laboratory, Tito co-founded investment-management firm Wilshire Associates in 1972. He was the first civilian space tourist to visit the International Space Station, paying $20 million (nearly Rs. 1,64,500 crore) to purchase a seat on Russia’s Soyuz rocket for a week-long stay. Tito said that, at the time, NASA wasn’t happy with his trip. 

Since his flight, space tourism has greatly expanded, and NASA has opened up the ISS to more commercial endeavors. Nearly a dozen tourists have flown there with the help of a company called Space Adventures. The first all-civilian crew visited the space station in April, coordinated by a company called Axiom. 

Paying customers are also able to get a brief taste of space by purchasing tickets on suborbital vehicles from companies like Jeff Bezos’s Blue Origin and Virgin Galactic, which send passengers to the edge of space and back.

SpaceX has also entered the space-tourism market. In 2021, an all civilian crew, sponsored by billionaire Jared Isaacman, flew into orbit for three days on a SpaceX Crew Dragon, a mission called Inspiration4.

‘To the Moon’

Tito’s plans came about when he visited SpaceX in June 2021 after a friend of his wife arranged a meeting with company personnel. He was asked if he wanted to go to space again, either to visit the space station or on a quick trip to orbit.

“No, I want to go to the moon,” Tito recalled saying. “And then I looked at Akiko just when I said that, and she said ‘me, too.’ And that’s how it started.”

Dennis Tito is 82 years old, which could make him the oldest person to go into orbit and into deep space. He acknowledged that he’s been focused on staying fit while waiting for Starship’s development. He and his wife, who is 57, are both pilots, while Dennis says he holds four American weightlifting records for an 80-year-old. 

“Whatever will be, will be. It’s going to take a certain amount of time, but it will be ready, and it will be safe when it’s ready,” Tito said. “It’s more limited by how much time I have on this planet.”

Voyager 2’s Flyby Sheds Light on Uranus’s Magnetic Mystery

Voyager 2's Flyby Sheds Light on Uranus's Magnetic Mystery

A recent analysis of 38-year-old data from NASA’s Voyager 2 spacecraft has provided fresh insights into the unique magnetosphere of Uranus, according to a study published on November 11 in Nature Astronomy. During Voyager 2’s 1986 flyby, Uranus’ magnetosphere was found to be unexpectedly distorted by a blast of solar wind. The findings suggest that the planet’s magnetic field behaves unlike any other in the solar system.

Findings Highlight Unusual Magnetic Structures

Jamie Jasinski, a planetary scientist at NASA’s Jet Propulsion Laboratory and California Institute of Technology, and lead author of the study, noted that Voyager 2’s timing happened to coincide with an intense solar wind event, a rare occurrence near Uranus. This compression of Uranus’s magnetosphere, seen only around 4% of the time, is thought to be responsible for the unique measurements Voyager captured. Had the spacecraft arrived even a week earlier, Jasinski observed, these conditions would likely have been different, possibly leading to alternative conclusions about Uranus’s magnetic characteristics.

Unlike Earth, Uranus exhibits a complex “open-closed” magnetic process, influenced by its extreme axial tilt. This tilt subjects Uranus to highly variable solar wind effects, resulting in a magnetosphere that opens and closes cyclically.

Implications for Future Uranus Exploration

The study’s conclusions go beyond Uranus itself, offering insights into the magnetic behaviours of its outermost moons, including Titania and Oberon. These moons, it turns out, lie within Uranus’s magnetosphere rather than outside it, making them candidates for investigations into subsurface oceans through magnetic field detection. As Jasinski highlighted, these conditions would simplify detecting any magnetic signatures that suggest liquid beneath the moons’ icy surfaces.

While Voyager 2 remains the only mission to visit Uranus, the study’s findings underscore a growing interest in exploring the ice giant in greater detail.

Tajikistan rock shelter reveals ancient human migration routes

Archaeologists have uncovered a rock shelter in Tajikistan’s Zeravshan Valley that was occupied by multiple human species, including Neanderthals, Denisovans, and Homo sapiens, for over 130,000 years. Discovered along the Zeravshan River in the Inner Asian Mountain Corridor (IAMC), this site, known as Soii Havzak, provides new insight into the migration patterns of ancient humans. Researchers believe the IAMC may have facilitated interactions between these groups, offering clues about how they lived and possibly coexisted in Central Asia.

Discovery Along the Zeravshan River

A team led by Dr Yossi Zaidner, senior lecturer at the Institute of Archaeology at the Hebrew University of Jerusalem, recently excavated the site. Evidence of various human occupations was found, including stone tools and animal bones dating from 150,000 to 20,000 years ago. Zaidner noted that Central Asia’s IAMC could have served as a natural migration route, allowing distinct human populations to cross paths. “This discovery is crucial for understanding ancient human presence in Central Asia and how different human species may have interacted here,” he stated in a press release.

Significance for Human Migration and Interaction

Artifacts from Soii Havzak, including stone blades, rock flakes, crafted flints, and signs of fire use, suggest repeated use of the shelter by different human groups. The find highlights Central Asia’s significance in ancient migration routes, with the Zeravshan River likely serving as a pathway for early humans as they dispersed across continents.

A Pathway for Ancient Civilisations

Beyond its prehistoric importance, the Zeravshan Valley later became a key route on the Silk Road, linking distant civilisations such as China and Rome. Researchers expect further studies at Soii Havzak to shed light on the broader implications of this region in ancient human migration and cross-cultural interactions, aiming to deepen understanding of human history and evolution during the Middle Paleolithic era.

NASA’s Juno shows Jupiter’s storms and moon Amalthea up close

NASA’s Juno spacecraft has delivered breathtaking images of Jupiter, highlighting the planet’s swirling, multicoloured storms and unique moons. During Juno’s 66th close flyby on October 23, the spacecraft approached the planet’s polar regions and captured close-up views of its fifth-largest moon, Amalthea. The raw images collected by JunoCam have since been processed by citizen scientists, who enhanced colours and contrasts to reveal Jupiter’s atmospheric details in a new light.

Spectacular Details of Jupiter’s Storms Revealed

Citizen scientist Jackie Branc processed one of Juno’s most striking images, showcasing a region on Jupiter called a Folded Filamentary Region (FFR), located near the planet’s subpolar areas. FFRs are known for their complex cloud patterns, which include white billows and fine, thread-like filaments. This recent image captures Jupiter’s stormy atmosphere with an emphasis on these fine details, giving scientists and the public alike a vivid view of the planet’s dynamic weather systems.

Juno’s data, available to the public online, allows enthusiasts and researchers to adjust image features such as contrast and colour balance. This collaborative effort has enabled a range of perspectives on Jupiter’s atmospheric bands, turbulent clouds, and powerful vortices.

Amalthea: A Close-Up of Jupiter’s Unique Moon

Juno also captured images of Amalthea, a small, potato-shaped moon only 84 kilometres in radius. In images processed by Gerald Eichstädt, the white balance was adjusted to distinguish Amalthea from the blackness of space, presenting the moon in stark relief. This view of Amalthea, with its rugged, irregular shape, adds to our understanding of Jupiter’s complex satellite system.

Launched in 2016, the Juno mission was originally planned to conclude in 2021, but its mission has been extended, with plans to end in September 2025. When its mission concludes, Juno will plunge into Jupiter’s atmosphere, marking the end of its successful exploration journey.
