Odd.. it isn't paywalled from outside the USA. https://www.washingtonpost.com/world...=.d5aac627e8c5 Direct link to the picture of it: https://img.washingtonpost.com/rf/im...EeiGuYkIdDx53Q The actual project link: http://www.thehumanitystar.com/ I reckon he would be better off launching a silver plated weather balloons into orbit to achieve the same objective with less mass. My instinct is that it won't be as bright as he hopes. -- Regards, Martin Brown |

I believe a smooth sphere would have very poor reflective qualities compared with flat, polished facets. The reflected, virtual image of the Sun in a smoothly convex surface is very small with little intensity. While even bare glass from [say] a greenhouse roof can be blinding from miles away. |

Here we have a much smaller surface, but probably a bit more reflective. Seems to me that its flares will be less than the brightest ones seen from Iridium satellites, but maybe more eye catching because of their rapid variation. |

What if it gets people to look up for a few moments from their mobile phones? They might ask themselves why the night sky is orange and appears to be falling. It certainly wasn't that low or even that colour when they were kids. |
