The usual summary of some of the space news worth discussing this week. I have provided a link and included my comments, so that you can go & pick the ones that interest you the most.
[This is a question I’ve asked myself many times in the last decade. After all, the basic design for Soyuz was established by Korolev in 1962. This article tries offering answers.]

[Observations of an unusual fast-spinning star – called J1723-2837 -may help explain why such stars, known as pulsars, fluctuate in brightness. ]
