These researchers want to run cable from the Earth to the Moon



It’s a space elevator concept that could actually work.

It would be much easier to escape Earth’s gravity if you could skip the energy-intensive rockets.

That’s the idea behind the Spaceline, a newly-proposed type of space elevator that would link the Earth and the Moon in a bid drastically cut the cost of space travel.

Described in research published to the preprint server ArXiv by researchers at Columbia University and Cambridge University, the Spaceline would be tethered to the surface of the Moon and dangle down into geostationary orbit around the Earth like a plumb bob, waiting for astronauts to latch on and ride into the cosmos. The proof-of-concept paper found that the Spaceline could be constructed out of materials that exist today, raising the possibility of easier space travel and perhaps even orbital settlements.

Can we get into space without big rockets?


Since humans began putting satellites into orbit in the 1950s, we’ve relied upon big, powerful rockets to escape Earth’s gravity and get into space. But big rockets have a major downside, in that they make space launches expensive. Case in point: NASA’s Space Launch System heavy lift rocket, which is scheduled for its maiden flight in December 2019, will cost an estimated $1 billion per launch, according to a 2017 report by NASA’s Office of Inspector General (OIG). Launch costs for SpaceX’s far more economical Falcon Heavy, which launched successfully from Kennedy Space Center in February 2018, still range between $90 million and $150 million for a fully expendable, maxed-out version, according to CNBC.

For decades, however, visionaries have looked for ways to get into space without relying — at least not primarily — upon rocket power.

Elon Musk tweets about space elevators and more


An Earth based space elevator would be around 62,000 miles long, or about 2.5 times the circumference of the earth.  It would take about 7.5 days to reach the GEO level traveling at 200 kph. Continue reading… “Elon Musk tweets about space elevators and more”

Obayashi Corp. is building the Tokyo Sky Tree and plans to build a space elevator by 2050.

Space elevators are one of the promising technologies of the future. Now a Japanese construction firm that specializes in the very tall could make them a reality. By 2050, so still pretty far on that horizon, but it’s a start.
