Meet Chrysalis: The spaceship that could be humanity's one-way ticket to a 400-year-journey to space!
While it remains purely conceptual, Chrysalis ignites our imagination and brings us face-to-face with serious questions like, What would it take to build a self‑sustaining civilization in deep space? How would future generations live, learn, and preserve their humanity as they move between the stars?

Engineers have proposed an extraordinary spacecraft named Chrysalis, envisioned to carry up to 2,400 people on a one‑way, multi‑generational journey to Alpha Centauri, the closest star system to our Sun.
The vessel spans 58 km in length, arranged in a concentric 'nesting‑doll' architecture with rotating sections to create artificial gravity.
According to Project Hyperion's official brief, launched as part of the Project Hyperion Design Competition, Chrysalis took first place for its system‑level coherence and imaginative yet cohesive design. Its internal structure comprises layers dedicated to different functions, including a central zone for food production, farms with tropical and boreal forests, fungi, livestock, microbes, and insects.
Apart from that, there will also be surrounding communal spaces such as parks, schools, libraries, and hospitals, residential shells with 3D‑printed modules, and the outermost zones serving as warehouses and industrial areas.
The most attractive feature of the spaceship
The 'Cosmos Dome', a microgravity viewing area showing transparent panels where people can move across weightlessly and take in the universe beyond, is an intentional design to encourage psychological well‑being.
How will Chrysalis work
Chrysalis would rely on nuclear fusion reactors, a technology not yet which has yet been developed, to power life support, machining, and habitat systems. The proposed journey spans roughly 400 years, meaning generations will live and die aboard before arriving, likely at Proxima Centauri b, a potential Earth‑like exoplanet.

The design is proposed to maintain a stable population of about 1,500 individuals over time, despite the total capacity being 2,400.
Social resilience would be supported by artificial intelligence, helping in the resilience of the whole social system, better knowledge transfer between the different generations of inhabitants, and a deeper vision of the overall dynamics of the Chrysalis spaceship complex,' according to the project brief.
Preparations for the initial crew would include 70–80 years of adaptation in isolated environments like Antarctica, to ensure psychological readiness for prolonged confinement in space.
While this is entirely theoretical, given our current inability to build practical fusion reactors or multi kilometer structures in space, the Chrysalis concept is an exploration into what our far-future outer‑space ambitions might look like.

James Webb Space Telescope rules out Earth-like atmosphere on rocky planet
The James Webb Space Telescope has found no signs of an Earth-like atmosphere on planet TRAPPIST-1 d, according to a study published Tuesday in The Astrophysical Journal. Using Webb's Near-Infrared Spectrograph (NIRSpec), researchers did not detect common terrestrial gases such as water vapor, methane or carbon dioxide, NASA said. 'At this point we can rule out TRAPPIST-1 d from a list of potential Earth twins or cousins,' lead author Caroline Piaulet-Ghorayeb said. TRAPPIST-1 d is a rocky planet in a seven-world system 40 light-years away. Orbiting a cool red dwarf at just 2 per cent of Earth's distance from the Sun, it sits at the inner edge of the star's temperate, or 'Goldilocks,' zone and completes an orbit every four Earth days, NASA noted. NIRSpec observations showed no spectral fingerprints of key atmospheric molecules. Piaulet-Ghorayeb outlined scenarios that remain possible: an extremely thin atmosphere like Mars; a cloud-shrouded world akin to Venus that hides gases from detection; or a bare, airless rock. 'There are a few potential reasons why we don't detect an atmosphere around TRAPPIST-1 d,' she said. Frequent high-energy flares from the system's red dwarf star can strip atmospheres from close-in planets, making retention particularly difficult. Even so, scientists continue to probe the TRAPPIST-1 worlds because red dwarfs are the most common stars in the Milky Way, NASA said. 'We're really just getting started… and to define the line between planets that can hold onto an atmosphere, and those that cannot,' added co-author Björn Benneke. Webb observations of planets e, f, g and h are underway. Their greater distance from the star could improve the odds of intact atmospheres, though colder conditions make detections tougher, according to NASA. 'All hope is not lost for atmospheres around the TRAPPIST-1 planets,' Piaulet-Ghorayeb said. 'As NASA leads the way in searching for life outside our solar system, one of the most important avenues we can pursue is understanding which planets retain their atmospheres, and why,' said Shawn Domagal-Goldman, acting director of NASA's Astrophysics Division. Results from Webb lay groundwork for future missions like the Habitable Worlds Observatory. (With inputs from NASA's official website)

Experts Warn Public To Avoid Rabbits With Dangerous Head Growths In Colorado
US experts have been alarmed by the sighting of the 'Frankenstein' bunnies with dangerous black head-spikes caused by a rapidly spreading virus. 'Frankenstein' rabbits with horrifying head spikes have been sighted in the United States of America. According to a report by the New York Post, these bunnies feature a terrible-looking set of spikes emerging out of their face. The report also claimed these black and dangerous spikes in cottontail rabbits are caused by a rapidly spreading virus. These Frankenbunnies with tentacle-like growths out of their heads were spotted by the locals in Fort Collins, Colo. One of the residents, Susan Mansfield, told 9News that she saw a rabbit with what appeared to her as 'black quills or black toothpicks sticking out all around his or her mouth." Mansfield confirmed she had seen the rabbit the previous year, thinking it would've died by now. 'I thought he would die off during the winter, but he didn't. He came back a second year, and it grew," the woman said. Another local described the infected cottontail rabbits as carrying 'a scabby-looking growth over their face." Experts Alarmed By 'Frankenstein' Rabbits With Dangerous Black Spikes The head spikes observed by these locals are indeed a sign of cottontail papilloma virus, which is also known as Shope papilloma virus that results in sprout tumours emerging around the head of the cottontail bunny. According to Pet MD, the virus spreads through parasites like ticks and fleas, passing on the ailment by biting the little bunnies. 'Typically rabbits become infected in the warmer months of summer when transmitted by being bitten by insects like fleas and ticks," said Colorado Parks and Wildlife spokesperson Kara Van Hoose, as quoted by The Coloradoan. Colorado may be the recent site of these bunnies with horn-like growths, but the disease is understood to have originated in the Midwest. In 2013, a Minnesota resident raised alarm bells among locals by posting a video of a tendril-ridden rabbit in his backyard, later calling it the 'Frankenstein' bunny. Wildlife Experts Warn Against Interacting With Bunnies Carrying Spikes US experts have been alerted by the sighting of the 'Frankenstein' bunny and have warned locals not to approach or handle any of the afflicted critters. In their report, Colorado Parks and Wildlife have clarified, however, that the cottontail papilloma virus can spread only between rabbits and is not found to infect humans or pets, which would provide relief to the concerned public. But the little cottontail rabbits are not as lucky. While there may be instances of the virus leaving these bunnies in time, in some cases, the Medusa-like protrusions can swell and interfere with the infected carrot eater's ability to consume food, causing starvation and death. view comments First Published: August 14, 2025, 12:03 IST Disclaimer: Comments reflect users' views, not News18's.

Meet Chrysalis: The spaceship that could be humanity's one-way ticket to a 400-year-journey to space!
Humanity has always looked to the stars with curiosity, hope, and a constant thought, what if one day we could journey beyond our solar system? Now, engineers have brought that dream a little closer by proposing a bold vision for interstellar travel, through a rotating spacecraft designed to ferry thousands on a centuries‑long voyage to the nearest star. While it remains purely conceptual, Chrysalis ignites our imagination and brings us face-to-face with serious questions like, What would it take to build a self‑sustaining civilization in deep space? How would future generations live, learn, and preserve their humanity as they move between the stars?
