In February 2026, Rosatom announced a prototype plasma rocket engine that its scientists claim could reduce the travel time to Mars from eight months to thirty days. The engine, built at a dedicated facility in Troitsk and tested inside a fourteen-metre vacuum chamber designed to simulate deep space, uses electromagnetic fields to ionise hydrogen into […].

The Republic of Paraguay signed the Artemis Accords on Thursday during a ceremony in Asunción, becoming the latest nation to commit to the shared principles guiding civil space exploration.
“Today, I am proud to welcome Paraguay as the 67th signatory to the Artemis Accords,” said NASA Administrator Jared Isaacman. “They join an ever-growing coalition of like-minded nations committed to the peaceful, transparent, and responsible exploration of space. Established by President Trump in his first term, the Artemis Accords provided the principles for how we explore the Moon, Mars, and beyond. Now, with his national space policy, we are putting the Artemis Accords into practice with our Moon Base. We are creating opportunities for all Artemis Accords signatories, including Paraguay, to join us on the lunar surface and advance our shared objectives in this next era of exploration.”
U.S. Embassy Asunción Chargé d’Affaires ad interim Aaron Pratt shared Isaacman’s remarks during the ceremony. Minister President of the Paraguayan Space Agency Osvaldo Almirón Riveros signed on behalf of Paraguay.
What if humanity could travel faster than light?
In this cinematic deep dive, we explore the different types of FTL (Faster-Than-Light) travel, including warp drives, wormholes, the Alcubierre drive, hyperdrive concepts, and other theoretical methods that could one day change space exploration forever.
From bending spacetime to creating warp bubbles and bridging distant galaxies, this video breaks down the science, theory, and science-fiction inspirations behind each method — in a realistic and visually immersive way.
Whether you’re a fan of space science, futuristic technology, or sci-fi universes, this is your ultimate guide to FTL travel.

Imagine a civilization reaches something like a Type II level, advanced enough to move through interstellar space and keep large populations alive for generations. At that stage, the challenge is developing ships that can cross the void, and also making sure the people inside them can survive radiation, isolation, and extreme travel times. That could mean heavy genetic engineering before the journey begins, changing bone density, metabolism, resistance to disease, tolerance for low gravity, or even sensory systems and respiration. But when they finally arrive, they may still find that the planet is wrong for them, maybe the air is toxic, the gravity is crushing, the temperatures are extreme, or the native chemistry is incompatible with human biology.
At that point, they face two paths. One is terraforming, which means trying to remake an entire planet into something closer to Earth. That could involve thickening or thinning an atmosphere, warming a frozen world, cooling a hot one, importing water, altering soil chemistry, introducing engineered microbes, building orbital mirrors or shades, and managing the planet for centuries or even millennia. The scale of that project is absurdly expensive, not just in money but in energy, infrastructure, labor, time, and raw materials. You are not changing a city or even a continent, you are trying to rewrite a whole world.
The other option is pantropy. Instead of forcing the planet to become Earth-like, the colonists change themselves to fit the planet. They might alter their lungs to breathe a different atmospheric mix, redesign their skin to handle harsher radiation, reduce their size for lower resource use, strengthen their bodies for higher gravity, or even become something so biologically different that they no longer look fully human. That is the core idea of pantropy, adapting the colonists to the world rather than adapting the world to the colonists.
The term was coined by James Blish, and he used it in connection with the stories collected in The Seedling Stars, especially “Surface Tension.” which was first published in 1952 in Galaxy Science Fiction.

Voyager 1 is losing power, and NASA just shut down a decades-old instrument to keep it going. The sacrifice could help the spacecraft continue exploring interstellar space a little longer.
On April 17, engineers at NASA’s Jet Propulsion Laboratory (JPL) in Southern California transmitted commands to switch off an instrument on Voyager 1 known as the Low-energy Charged Particles experiment, or LECP. The spacecraft, which runs on nuclear power, is steadily losing energy, and shutting down this instrument is the most effective way to extend the mission of the first human-made object to reach interstellar space.
