    Here's a video about the moon's gravity well.
    https://www.youtube.com/watch?v=VBQHtF3WhMw

    It concludes by saying "We could build space stations, power satellites, or spaceships, using raw materials launched over the curve of the moon's gravity dimple and let these lunar materials roll downhill to high orbit around the Earth."

    But this is merely one of many possible outcomes, and it's only a long-term possibility. It's not going to happen any time soon. In the meantime, the legal ramifcations are being studied by many participants, and new laws are on the horizon.

    When Commercial Space establishes its footholds, the attorneys will be right alongside with their chinks and their chock blocks. Let's hope they get it right.

    Not only that, but where are all these raw materials going to come from? We'll find water and helium on the moon, but what about the rest? We'll have to go after the asteroids.

    If we go get some small asteroids, should we shoot them and/or their ore directly to a space station in Earth orbit? That's just asking for trouble.

    It would make a lot more sense to send them to an LZ on the moon, then process them in a mill and build the space stations and satellites in factories there. That way, the factories would have many raw materials at their disposal, and they could sustain themselves much more readily, safely, and cheaply than mere containers floating in space.

    For example, the moon's regolith (dirt) could be used for building construction, insulation, and protection from micrometeoroids. Oxygen and hydrogen could be genereated from ice. When burned, the hydrogen would turn back into water.

    Gravity would make most processes easier. It would also eliminate surprises in the performance of routine chores. Things would be where you left them, and not jamming up the works somewhere.

    Of course, many things will be done right at the asteroid. Ore will be processed and parts will be printed. Spiderfab robots will build trusses and large, light-weight structures. But there will be other processes, and many of them will be best handled at a remote, environmentally controlled, ground-based facility.

    Would you or someone you know like to design a 3D printed habitat, suitable for Earth or the Moon or Mars?

    Would you like to try for a $50,000 prize?

    NASA Could Return Humans to the Moon by 2021

    Humans could return to the Moon in the next decade, and for "approximately 90% less than the previously estimated $100 billion," according to a new study by NextGen Space.

    NASA can cut the cost of establishing a human presence on the Moon by utilizing existing partnerships with commercial service providers like SpaceX and Boeing, said Charles Miller, NexGen president and the study's lead author.

    By tapping those partnerships, NASA could put humans on the Moon in five to seven years and even build a permanent base 10 to 12 years after that – all without exceeding its current $4 billion budget for human spaceflight, the study said.

    They are having us back because we have helped them stay off the public radr.

    Bigelow Aerospace and NASA Execute NextSTEP Contract to Study B330 Utilization

    NASA has executed a contract with Bigelow Aerospace for the company to develop ambitious human spaceflight missions that leverage its innovative B330 space habitat. The contract was executed under the Next Space Technologies for Exploration Partnerships (“NextSTEP”) Broad Agency Announcement issued by NASA’s Advanced Exploration Systems program.

    Via its NextSTEP contract, Bigelow Aerospace will demonstrate to NASA how B330 habitats can be used to support safe, affordable, and robust human spaceflight missions to the Moon, Mars, and beyond.

    I still think that we need to focus on non-rocket propulsion to get both materials and people off-planet. Even if Musk's wildest dreams come true, rocket launches will still be prohibitively expensive in the long term. More than any other space dream, we should be focusing on getting into orbit on a dime.

    Free Lecture: NASA-Funded Economic Analysis of Establishing a Moon Base

    This lecture has a long, boring introduction. Jump to 5:00. If it's still too boring, jump to 12:00.

    GLXP Updates: Aldrin & Pickens Leave Moon Express, Lunar Lion Withdraws

    Two high profile executives — President Andrew Aldrin and Propulsion Vice Pesident Tim Pickens — have left Bob Richard’s Moon Express, the commercial exploration company that has been one of the favorites to win the $30 million Google Lunar X Prize for landing and operating a rover on the surface.

    Meanwhile, the only student-led team in the race, Penn State Lunar Lion, has withdrawn from the prize after an independent review found it could not achieve that goal within the competition’s tight deadline of Dec. 31, 2017.
