The animation describes the concept of launching a nuclear fusion reactor into orbit in sections for final assembly in space. The concept uses live footage of Pulsar’s existing hall effect plasma thrusters (HET) and hybrid rocket engines tested at RAF Westcott in March 2022. Pulsar is also developing LOX / Methane rocket motors to support this concept.
The ambitious proposal could help realize Elon Musk’s vision of SpaceX’s Starship as a “futuristic Noah’s Ark”.

Dreaming of an Earth-like environment on Mars.

The “extraterrestrial nature reserve”, or ETNR, would take the form of a greenhouse-like “forest bubble” designed to create an Earth-like ecosystem on the red planet. It would allow humans to experience a slice of home on Mars while also acting as a sustainable source of food and raw materials for early inhabitants.
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.

Year 2008 o.o!
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?

By choosing the right path and the right reference frames, any superluminal motion can lead to information or objects returning to their origin before they depart. Matt O’Dowd will show you how to navigate such a path.

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.

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.
They will collaborate with the Universities of Cambridge and Southampton, as well as Nuclear AMRC to make their vision of green rocket technology, in the form of fusion propulsion, a reality. Fusion / YouTube.
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.”
