Humans will launch aboard NASA’s Orion spacecraft for Artemis II, which is currently slated for a 2024 launch.

Incredible new footage from NASA’s moon mission Artemis I looks straight out of a Christopher Nolan sci-fi epic.

Lockheed Martin, the company that built the Orion spacecraft, shared the launch footage on its Twitter page, allowing viewers to imagine what it will be like for astronauts aboard NASA’s crewed Artemis II mission.

That is so fantastically ridiculous and dangerous… not that the laser is terribly dangerous; more for the incredibly fast print head. the video reminds me of “Starship Troopers”, i love it. it’s probably not deep, i wonder if they heal up after a few months.

Make a small one, get it FDA approved! it’s the wave of the future!

Time travel makes great science fiction, but can it really be done? Travel into the future is already a reality, but visiting the past is a much tougher proposition, and may require fantastic resources such as a wormhole in space. Nevertheless, if going back in time is allowed, even in principle, then what about all those paradoxes that make time travel stories so intriguing?

He is the author of many books, including “How to Build a Time Machine” and, most recently, “The Eerie Silence: are we alone in the universe?”

How China plans to catch and reuse its next-generation rockets. Seems like a unique approach compared to SpaceX’s plan to catch a booster with the launch tower.

An overview of China’s “other” Lunar super-rocket.

The space firm has already built the most powerful electric propulsion engine in Europe.

Nuclear fusion-powered rockets might be nearer than you think. UK rocket company Pulsar Fusion has been awarded funding from the UK Space Agency to help it develop “integrated nuclear fission-based power systems for electric propulsion”, a press statement shared with IE via email reveals.

The private space firm fired up 11 of Booster 7’s 33 next-generation Raptor engines.

SpaceX is making steady progress towards the orbital maiden test flight of its massive Mars-bound Starship rocket. The private space firm conducted a “static fire” test on Tuesday (Nov .29), at its South Texas facility. It ignited a total of 11 of 33 next-gen Raptor engines on its Starship first-stage Super Heavy prototype, Booster 7.

The static fire engine test started at 2:42 pm EST (19:42 GMT) and lasted for 13 seconds. On Twitter, SpaceX shared an image and wrote, “Booster 7 completed a long-duration static fire test of 11 Raptor 2 engines on the orbital launch pad at Starbase.”

In science fiction – think films and TV like “Interstellar” and “Star Trek” – wormholes in the cosmos serve as portals through space and time for spacecraft to traverse unimaginable distances with ease. If only it were that simple.

Scientists have long pursued a deeper understanding of wormholes and now appear to be making progress. Researchers announced on Wednesday that they forged two minuscule simulated black holes – those extraordinarily dense celestial objects with gravity so powerful that not even light can escape – in a quantum computer and transmitted a message between them through what amounted to a tunnel in space-time.
