Novelist Karl Schroeder has an intriguing possible answer to Fermi’s Paradox, i.e. the question “Where are all those aliens?". I’ve lately been trumpeting my revision of Clarke’s Law (which originally said ‘any sufficiently advanced technology is indistinguishable from magic’). My revision says that any sufficiently advanced technology is indistinguishable from Nature. […] Basically, either advanced alien civilizations don’t exist, or we can’t see them because they are indistinguishable from natural systems.
How small satellites are radically remaking space exploration is a nice quick overview about the ongoing small-sat and small-rocket space industry revolution. 🚀
Now, two emerging technologies may propel NASA and the rest of the world into an era of faster, low-cost exploration. Instead of spending a decade or longer planning and developing a mission, then spending hundreds of millions (to billions!) of dollars bringing it off, perhaps we can fly a mission within a couple of years for a few tens of millions of dollars. This would lead to more exploration and also democratize access to the Solar System.
In recent years, a new generation of companies is developing new rockets for small satellites that cost roughly $10 million for a launch. […] The concept of interplanetary small satellite missions also spurred interest in the emerging new space industry.
