[QUOTE="Paranormalis, post: 95410, member: 2585"] Launching deep space probes is great, but to really explore space and unlock its secrets, it sure would be helpful if getting there were as easy as pressing a button. That's the vision of Liftport, which Gizmag first reported on back in 2012. Now, more than two years after Liftport raised over US$100,000 on Kickstarter, the team is sharing its progress towards creating an elevator from Earth to space, a journey that – interestingly enough – begins on the Moon. Building an Earth-to-orbit elevator is beyond tricky at the moment due to the relative abundance of gravity, weather and water around our planet. We've yet to perfect the material that could create a ribbon long enough to support an elevator that won't collapse under its own weight or run into problems with ice in the upper atmosphere. But those challenges are significantly lessened when you attempt to do the same thing from the Moon rather than Earth. Much less gravity and a lack of a wet atmosphere make the Moon the ideal testing ground for constructing a space elevator. Which is why Liftport is currently focusing all its energy on building a lunar elevator by the end of this decade. The plan for the lunar lift revolves around a space station called the PicoGravity Lab that will be positioned at the lunar LaGrange point – the spot in space that is exactly between the gravitational fields of the Moon and Earth. From that point, a Kevlar ribbon will be anchored to the Moon's surface via a docking port as shown in the video at the end of this post. This isn't your average ribbon, though. It will stretch 250,000 km (155,350 mi) towards Earth, where a counterweight within our planet's gravity well will help keep it taut.
