spacex has successfully landed stage 1 boosters from one of their rockets, which will lead to significantly cheaper space missions and lead to fully reusable rockets in the not so distant future. the price of launching a full rocket has gone from hundreds of millions for the cost of building a new rocket, to just tens of millions for refurbishing one. This is so important and i don't even know what to say right now, so i'll let you guys watch this instead.
