The Space Elevator from Wandering Earth 2: The climbers seem to be entirely rocket-powered, which removes most of the benefit of having a space elevator in the first place.

🔥🚨DEVELOPING: Japan is building an ‘elevator to space’ for humans to experience what space looks like in person by 2025. Obayashi Corporation, which built the Japan's tallest tower, plans to start building a space elevator in 2025 with the aim of it being operational by 2050. That's the same year Japan hopes to achieve carbon neutrality. The construction process is expected to be done in several stages.

NEW: Chinese rocket which was developed to rival Musk’s Space X, crashes into a mountain side. The Tianlong-3 rocket accidentally lifted off during a static fire test according to The Telegraph. After launching into the air, the rocket was seen falling back to Earth, exploding into the mountainside near the city of Gongyi in Henan Province. The rocket was owned by private Chinese business Space Pioneer. Space Pioneer claims a “structural failure” of the launch moorings which were supposed to hold the rocket in place resulted in the accidental launch. Reports say there are no casualties at this moment.

ELON MUSK: "The most obvious one is actually solar powered AI satellites, sort of to move the AI to orbit and essentially deep space over time, because there you can actually access over a billion times more energy from the sun in deep space than you can on Earth. The scaling to Kardashev, which is using some non trivial amount of energy from the sun. You kind of have to do space solar power. Like to even use a millionth of a percent of the sun's energy you you really have to be have your solar power in deep space."

Syntilay is announcing an unprecedented mission to design shoes in space! We will be deploying an AI agent on a computer in a satellite that will generate the first shoe design outside of earth in human history! This mission, taking place on a SpaceX rocket in early 2026, will push the boundaries of automation in footwear design to heights never seen before. The first shoes made in space are planned to release in late Q2 2026 for $200! Which will be 3D printed with our preferred production partner Zellerfeld. Thank you to all of our partners from Copernic Space which has the goal to democratize space access, OrbitsEdge which creates the space computer, to Joe and Julie Foster for their support. This is a piece of history and only possible with Syntilay’s AI-Design approach. The future is now! Cornelius Schmitt 👨‍🚀Copernic Space🚀

I updated my Esperanta orbiter model to serve as a terminus station for a space elevator in the new film "Engineering Earth" by Melodysheep (melodysheep). Here is a selection of the shots I made for the film.

Astranis CEO John Gedmark calls space elevators the ultimate civilizational flex: if aliens come and find us and we don't have our space elevator up and running yet, that's embarrassing "I like space elevators. This is the idea that originally came from Arthur C. Clarke, who also was the person who came up with the idea of geosynchronous orbit." "He came up with this idea of once you build out infrastructure in that orbit, you could build this thing called a space elevator. It sounds a little crazy. Hundreds of years away, could be thousands. It does not actually violate any laws of physics. It's arguably doable with technology we have today." "The best way to think of it is you have this orbiting platform in geo, and you have a very long cable that hangs down and comes down to the surface of the earth. You anchor it, and then you could have essentially elevator cars running up and down this cable." "It completely eliminates the need for rockets at all. The cost is just the cost of the electricity to run these cable cars." "It's actually an inevitable thing. It just may be on the multi-thousand-year timescale. But we gotta do it. A space elevator is the ultimate civilizational flex. Aliens come and find us, and we don't have our space elevator up and running yet? What are we doing? We can't allow that."

CNN journalists were shown the wreckage of the first Russian Oreshnik that attacked the Dnipro in 2024. Among the components of the rocket are the same parts as on the rocket on which Gagarin first flew into space.

🔥 Exactly a decade ago, we ignited our first rocket engine. Today, we’re igniting Europe’s path to space. Since 2015, we’ve grown into the largest private European developer of rocket engine technology, with the ability to design, manufacture, test, and fly liquid-fuelled rocket engines entirely in-house. With the TEPREL engine family, we’ve successfully demonstrated spaceflight-proven technology. Now, with TEPREL-C, we’ve taken a bold step forward, with our first fully internally developed turbopump, one of the most complex subsystems in propulsion engineering. At PLD Space, we're not just following the path, we're defining the future of space access.

ELEVATOR EMERGENCY: Two people were rescued after an elevator became stuck between floors in a downtown Indianapolis building. The occupants told crews the elevator was traveling from the first to the sixth floor when it abruptly stopped, shook, and displayed an “out of service” message.
