Vertical lift heavyweight Sikorsky predicts that hybrid-electric propulsion systems will generate significant performance ...

Two leaders behind the Seattle Space Needle's massive redesign say it was a huge undertaking and one that was crucial to preserve the city's iconic landmark.

A space elevator can serve two purposes—get the materials off of the surface and use leverage to fling them on a trajectory much faster than launching from the surface itself would be.

Before the ISS dies, however, it will help birth its own replacement—one that will be built and launched by the private sector, with the new modules constructed by Houston-based Axiom Space, and ...

Inspired by early sketches of the Space Needle, the new double deck elevator design honors the tradition of innovation and forward-thinking that created the Space Needle back in 1962.

The Space Needle's new Skyliner elevator, the first of its kind in North America, opened to the public on Friday.

For decades, the staggering cost of escaping Earth's gravity has limited our reach into space. Sending just one kilogram into orbit can run tens of thousands of dollars.

Imagine the engineering marvel and potential for easier space access with the construction of a space elevator.

The energy cost of a reusable rocket can be made zero by building solar panels and electrolyzers to make fuel for the rocket - instead of a mass driver or a space elevator.

Space elevators? Nuclear rockets? The future of space travel could look radically different.
