Snowboarding Trip
Really trying to trip out to Colorado soon...anyone want to tag along (read: make the trip relatively cheaper) and share a room or a house or whatever
New technology that will change the world(s):
1. Ion Propulsion
(Image credit:Â NASA/JPL)
Technically not upcoming, ion propulsion is already a reality. Since it propels a spacecraft one particle at a time (as opposed to chemical propulsion, which explodes, generally, out the back), this propellant is hugely efficient.
The trick is whatâs known to physicists as âspecific impulseâ. When a chemically propelled vehicle propels, it causes an explosion out the back, pushing the object forward. After exiting the vehicle however, the explosion immediately spreads in all directions, meaning that much of the energy of the explosion is lost on direction other than the one the spacecraft wishes to move.
Ion propulsion takes a long time to build speed but is so efficient that NASAâs Dawn spacecraft, being an ion propelled machine, is the first to be able to orbit multiple things in the solar system.
With ion propellant, a spacecraft may be able to even generate enough speed to allow for interstellar space exploration (meaning it could enable us to leave the Solar System). Though speculative, the possibility is undeniable.
2. Solar Sailing

This technology is still controversial. The science is this:
Light has momentum. When light hits a highly reflective surface, the surface, is pushed. With gradual building of velocity, a spacecraft could easily attain vast speeds, again leading to aspirations toward interstellar exploration.
The advantage over ion propulsion though, is that this is exploration without propellant.
Such methods of discovery havenât been relevant since our ancestors explored the Earth on boats driven by the wind.
Though the science is known, the engineering applications are still somewhat mysterious.
The momentum gained from a single photon is very small. The area of material needed for a solar sail that could carry something like a generation starship is many orders of magnitude larger than any tested solar sail concept. Itâs arguable whether or not this technology would ultimately turn out to be the most efficient way to go.
That space exploration is expensive means that when someone bothers to pay for a launch, the first thing they would hate to do is lose their spacecraft because it turns out to not be able to propel itself. Most bankrollers of space travel tend to favor tried and true methods.
That said, the testing of solar sails is underway.
Agencies like NASA, JAXA and even the Planetary Society (holla) are currently undergoing mission preparation, or already have a mission underway, testing solar sails.
3. Renewable Rocketry
(Image credit: SpaceX)
This oneâs a biggie.
Imagine, you buy a car. You go buy groceries, come home and then your car explodes.
Every. Single. Time.
Tell me, could you afford to buy a new car every week to buy groceries, or would you figure something else out?
Personally, I wouldnât be able to travel by car. I just donât have the money to buy a new one every week.
Space exploration faces the same problem. Rocket technology was mostly driven and invented by military ventures that didnât care about getting the rocket back. In fact, for a military rocket - if you see it coming back at you then youâve probably done something wrong.
New efforts are underway to change this.
Companies like SpaceX, Reaction Engines and Blue Origin are devising groundbreaking new technologies that are fundamentally different from the rocketry of yesteryear.
Soon SpaceX will be carrying people into low Earth orbit, dropping them off and returning to a landing pad in Florida.
Reaction Engines Ltd has invented a hybrid rocket engine which breathes oxygen from the atmosphere like a jet engine, then becomes a spacecraft engine once the air becomes too thin (meaning it needs a fraction of the fuel to get to space as most others).
Blue Origin plans on carrying tourists to the edge of space, with the rocket then returning to the landing pad softly on a plume of fire.
Each of these ventures has already proven their technology. Theyâre each on the road to implementing it now, with both SpaceX and Blue Origin currently launching with the technology.
Let me give you an idea of how much this is going to change humanity:
The cost of a SpaceX Falcon 9 launch is around $61 million.
Of that, the cost of fuel is about $200,000 (according to SpaceX).
In two years, SpaceX will be regularly launching seven astronauts at a time to the space station.
If all you need to pay for (approximately) is the cost of fuel (similar to fueling up your car), the cost of fuel between seven to get to space drops to a potential $28,500 or so.
Though still expensive, itâs easily within the bounds of startup companies to launch to space on commercial endeavors, meaning there will be private sector astronaut positions opening up in the very near future (they already exist actually).
Some vacations cost more than this. Itâs within the bounds of reason to expect such entertainment prospects to carry into orbit.
Imagine: zero-gravity theme parks and floating hotels where you can watch, romantically as the Sun sets on the Earth below 16 times a day and you can see the Northern lights, lightning storms and the artificial spark of city lights spread out below you like some wondrous surreal painting.
With companies already developing espresso machines and cups for microgravity, and astronauts already testing greenhouses that grow vegetables in orbit, it seems inevitable that humanity is on the cusp of realizing the experience of the final frontier.
