Most of what we have learned about living in space is that we should not live in space.


The heliospheric current sheet results from the influence of the Sun’s rotating magnetic field on the plasma in the interplanetary medium (solar wind). The wavy spiral shape has been likened to a ballerina’s skirt. Wikipedia

The Place Diagram
PPS Project for Public Space, 2003

Imagine that the center circle on the diagram is a specific place that you know: a street corner, a playground, a plaza outside a building. You can evaluate that place according to four criteria in the red ring. In the ring outside these main criteria are a number of intuitive or qualitative aspects by which to judge a place; the next outer ring shows the quantitative aspects that can be measured by statistics or research.

Note 1: There is a more recent diagram, with contemporary colors, in the article linked above, but this one from 2003 is for me more legible.
Note 2: We can learn a lot from urban planning for designing Web communities.

Fermi’s Motion Produces a Study in Spirograph
NASA Goddard Photo and Video, 2013The Vela pulsar outlines a fascinating pattern showing 51 months of position and exposure data from Fermi’s Large Area Telescope (LAT). The pattern reflects numerous motions of the spacecraft, including its orbit around Earth, the precession of its orbital plane, the manner in which the LAT nods north and south on alternate orbits, and more. This image compresses the Vela movie sequence into a single snapshot by merging pie-slice sections from eight individual frames.
Note: I like that this beast has a tongue.
