Space Launch Costs Will Become Increasingly Irrelevant

Historically, one of the greatest impediments to the process of humanity moving out into space has been the extreme costs of launching payloads out of our gravity well. There are two factors that will contribute to a dramatic decrease in the affect of launch costs on space migration. Space elevators will greatly reduce the effort […]

Planet Earth Seen From Space

Jeff’s Earth – 4K – [youtube.com] The first time you see Planet Earth from space, it’s stunning; when you’ve spent 534 days in space—more than any other American—it still is! On his most recent trip the International Space Station NASA astronaut Jeff Williams used an Ultra High Definition video camera that he pointed at the […]

Education Needed For Living in Space

We tend to take for granted that anybody can leave Earth and go into space and that is generally true. But it’s also true that most people who have actually done this are highly educated. The first astronauts were mostly highly trained military test pilots. This means they had college degrees, military officer training, and […]

Juno Arrives at Jupiter

It has taken NASA space probe, Juno, nearly five years to reach Jupiter after traveling over 1.7 billion miles. Juno is now in orbit around Jupiter and NASA hopes to study Jupiter using images and data being relayed back to Earth. At present, it takes transmissions 48 minutes to return to Earth. Juno spacecraft trajectory […]

A Cable Made From Diamond Nanothreads

The concept of a space elevator was just a theory when it was conceived, because no known substance was strong enough to suspend its own weight at the huge distances involved (around 100,000 kilometers). But then, carbon nanotubes were discovered, and they have the required strength to make the cable for a space elevator, when […]

Allen, Bezos, Branson, Musk: A New Space Race

NASA is headed toward irrelevance. The future of space exploration will be done by private companies. The early pioneers include: Paul Allen (money from Microsoft) – founder and CEO of Vulcan Inc, including a division known as Vulcan Aerospace, and its subsidiary, Stratolaunch Systems, which is developing an air launch vehicle capable of carrying an […]

Space Elevator Fundamentals

A space elevator is a long thin cable, anchored on the Earth end and held in place on the space end by a counterweight of ballast. The central balance point of the cable is located at a geo-synchronous orbit level, keeping the cable steady over the anchor point. The weight of the cable (and ballast) […]

Objects in Space Beyond Neptune

Objects in Space Beyond Neptune

Pluto was once categorized as a planet, because we didn’t have a clear definition of what a planet is and because the objects we called planets were basically all the large objects we found orbiting the Sun. But then things changed. Around the year 2000, a team of astronomers headed by Mike Brown began discovering […]

First Contact Protocol

When we make first contact with another species of life, we should have a first contact protocol already thought through to guide our actions. This protocol can’t anticipate all possibilities and chart precise actions to be taken, but it can establish some general principles and important ethical considerations. ASSESSMENT An early priority should be to […]
