A Vision for the Near Future
Obama's decision not to return to the Moon HAS BEEN REJECTED. Ignoring the Moon because "we've been there, done that" is simply absurd when there is so much we can learn by being there. Other entities (China for one) are planning their own lunar base and space stations...and it is highly likely that some entity will militarize those platforms. Don't believe that a "treaty" prevents someone from militarization of space - once an entity can establish itself there isn't much anyone else can do to make them compliant.
Since the launch of Sputnik only the old Soviet Union and the United States of America developed the the technology to get into and survive in space. Of course both sides worked with (and paid for) commercial or state partners. Multinational operations began with the International Space Station (ISS). Currently a new international partnership is underway called Gateway .
Todays space technology requires massive rockets to launch from the surface of the Earth with enough power to orbit Earth gaining additional speed before leaving orbit for the Moon, Mars or anywhere else. Propellant is required to break the spacecraft acceleration, place it in any kind of orbit, keep the orbit, perform operations, break orbit and head back for a direct hit on Earth. At the end of the mission very little is left of the original launch craft.
Our labs are exploring new propulstion technologies, creation of energy fields, energy containment and more. We have people like Bigelow leading the way with expandables. We have commercial entities working on returning our astronauts into Low Earth Orbit (LEO) and developing the capability of taking them beyond. All of these certainly takes money but these efforts are underway and don't require "new starts".
Our Apollo space program showed we could safely mate components in Earth orbit before pressing on to the Moon. We can still do this but there will be a time that the orbital junkyard becomes a real threat to anything below and passing through it. Cleaning up this junkyard is going to take time and it's going to take new technology.
I like what the corporate sector has accomplished and where it's going...although I'm not thrilled about their timelines continuing to slip out. Until President Trump was elected there wasn't a whole lot of benefit to the corporate sector.
I want to go to Mars. - by that I mean I want to stand on the surface of that planet and go below its surface. We must learn and invest in research and development. There is no better place to do this than on the surface of the Luna - our moon.
I have exciting news coming!
