Thanks to recent advances in materials science, Space Elevator s have become somewhat feasible at last. 🧐 engineering
Thanks to new technologies, we may finally be able to built a Space Elevator !
. For some time, scientists have considered this to be one of the most promising means to combat global warming. By being able to lift heavy payloads to orbit for pennies on the dollar and without depositing tons of carbon in the atmosphere, Space Elevators could also help solve the climate crisis.
As for the cost of manufacturing such a megastructure, that may be the most encouraging news of all. Dr. Swan, Nixon, and colleagues estimate it can be done for a very reasonable $18 billion, less than whatNASA currently spends annually. What's more, their projections indicate that production could begin before the end of the next decade. Said Dr. Nixon:

The reason for this is to share with you an idea of a system to clean the atmosphere, the ozone layer of pollution generated by man, with the idea that I propose, the atmosphere can be largely cleaned, and thus avoid global warming and all its consequences. Tal vez en 20 años el mundo vivirá una explosiva expansión si esto se materializa
Watch the James Webb Space Telescope soar through space in this livestream SaturdayWatch the James Webb Space Telescope soar through space in this livestream today! Really. Did you watch a huge meteorite fly through space and nearly hit Pittsburgh? So all the stars are oblong but the JWS scope isn’t? 🤣
Gorgeous HD Footage Shows Humanity's Final View of The James Webb Space TelescopeWe can all breathe a bit easier now. In spite of a launch bedeviled by problem after problem, NASA 's James Webb Space Telescope is finally in space, making its way to its new home. Are they blowing it up?
Rail historians raising $25K for space to restore trains, eventually become N.J. museumA railroad historical group finally has an indoor ace to restore and preserve the rolling artifacts of the states transportation history and strives toward a future goal of having a state transportation museum. What happened to the one at Allaire? You sure it isn’t just so NJ Transit can use them? njcommute
Japan billionaire Maezawa: going to space makes you obsessed with EarthJapanese billionaire Yusaku Maezawa, newly returned to Japan after a 12-day journey into space last month, said being launched into the cosmos was less scary than riding a rollercoaster and made him obsessed with Earth .
Space telescope's 'golden eye' opens, last major hurdle NASA 's new space telescope, the James Webb Space Telescope, opened its huge, gold-plated, flower-shaped mirror, the final step in the observatory's dramatic unfurling.
NASA January Launch Studying Sources of Space X-raysComing up: At 11pm ET, the launch window opens for a sounding rocket mission studying low-energy X-rays. Live in the U.S. mid-Atlantic? Weather permitting, you may be able see the rocket in the sky. Follow NASA _Wallops for updates: _Wallops Y'all say this and every time I listen and go outside. No matter how cold l, dark, hot whatever. Yet I never see anything. I'm in the visibility zone so I don't know what the problem is. 🤷 _Wallops It’s possible if we can see it from Canada Calgary _Wallops It won't see nothing

For some time, scientists have considered this to be one of the most promising means to combat global warming. By being able to lift heavy payloads to orbit for pennies on the dollar and without depositing tons of carbon in the atmosphere, Space Elevators could also help solve the climate crisis. To view the space telescope zipping through space, enthusiasts can watch a live feed provided by the Virtual Telescope Project. As for the cost of manufacturing such a megastructure, that may be the most encouraging news of all. It's headed for a location some 1. Dr. Masi makes observations from Ceccano, Italy, located about 56 miles (90 km) south of Rome. Swan, Nixon, and colleagues estimate it can be done for a very reasonable $18 billion, less than what NASA currently spends annually .m.
What's more, their projections indicate that production could begin before the end of the next decade. From L2, Webb will be able to peer through the universe in depth, helping scientists learn about the earliest moments of the universe and providing a better understanding of Earth's own cosmic neighborhood. Webb will sit in the second Lagrange point – there are five in total – on the far side of Earth from the Sun, also known as L2. Said Dr. Nixon: "If we push the manufacturing cost assumption down to one cent per square meter, then we come in at $3. Follow us on Twitter @Spacedotcom and on Facebook.6 billion for the manufacture of the tether. Because it's so much farther from Earth than Hubble, the Webb space telescope will need to operate with minimal human involvement. Now we have a long way to go to get there, but the experts see the future, the need for space elevators, and the [demand for] transportation infrastructure. But first, that place needs some work.
As such, this leaves you with $14.4 billion for the rest of the Space Elevator segments. Ariane 5's parting footage will be the last time we clap eyes on Webb for some time, if we ever do again." "One key is that the material prices are falling, and the technology is accelerating towards real production techniques for industrial uses," added Dr. Swan."This external (from SE) demand is pushing the tether production technologies. The latest acquisition, a locomotive that ran on the streets of Hoboken before waterfront industries were replaced by condos and townhouses, was preserved last year and will be displayed in the UHRS facility sometime this year.
We, the SE people, love what is going on and see the material being ready for us in time for an operational date of about 2037." *          *          * There's a reason why interest in the Space Elevator has endured all this time. While it was once thought to be the stuff of science fiction, then a far-off prospect, the day is fast approaching where it will be a feasible possibility. The main stumbling block is now gone with the isolation of graphene and the development of an industrial manufacturing capacity. Of course, there are still some challenges that stand in the way of realization.” The building, recently vacated by a tenant, would allow UHRS members to work on equipment indoors as efficiently as possible, Phalon said.
As Dr. Swan, Nixon, and Nelson all explained, they can be broken down into three categories. First, there's the issue of scale, as manufacturers still need to develop the capacity to create graphene sheets that are kilometers in length.  Second, there's the issue of speed, where production needs to be ratcheted to several meters per minute (or even per second). Third, there's the issue of quality control, where single-crystal sheets (rather than polycrystalline) of graphene need to be produced, and tests need to be devised to gauge the quality at the nanometer, meter, and kilometer scale. “A simple paint job can add decades to the lifespan of any car or locomotive in this yard.
But compared to the previous hurdles scientists had to deal with, these ones will be entirely surmountable with time. Already, many researchers are working on solutions to these issues. And given the rate at which things are progressing, it shouldn't be long before all the feasibility assessments agree that it can be done. Then, as the saying goes,"the only thing left to it is to do it!" Advertisement Stay on top of the latest engineering news Just enter your email and we’ll take care of the rest: SUBSCRIBE .
