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 […]

The Horseshoe Orbit Asteroid

Asteroid 2010 SO16 follows an orbit close to the orbit of Earth. Sometimes it’s a little closer to the Sun at about 0.996 AU and sometimes it’s a little farther from the Sun at 1.004 AU. When the orbit is inside that of Earth, the asteroid travels faster than Earth and slowly catches up to […]

Quintessence Means Fifth Element

FOUR ELEMENTS Plato defined four basic elements as earth, water, air, and fire. In his analysis of geometry he defined five regular solids. He paired up the four elements with four of the five regular solids and this suggested to him that there might be another element. He assigned earth to the cube, water to […]

Printing Space Habitats

3D printers work by extruding materials in patterns and building up layers of the material into three dimensional objects. The greatest cost of building structures in space is simply lifting the mass of the materials up out of the gravity well we live in. If materials to build with can be provided in space without […]

Space Transport

In space, the dividing line between what is considered to be a habitat and what is considered to be a vehicle will become hazy. Large habitat-like structures can be put into orbits that offer transport from one place to another and from one orbit to another. A habitat placed in an orbit that goes from […]
