- It is possible, if you can move fast enough, to outpace the shadow of the Moon. In 1973 someone actually did this: they took a prototype of Concorde, cut holes in the roof for cameras and telescopes, and then flew at speed across the deserts of northern Africa. #science #space #astronomy #esa

- It now appears that the US space tracking network failed to detect the reentry infrared flare from the Kosmos-482 SA. We are left with the European radar data and model estimates such as those from the TU Delft group and from Roskosmos.
- Is the US network based solely on ground assets or they have satellites too? I wonder if any observation satellites could have picked something up?
- The Kosmos spacecraft probably came down over the Indian Ocean, though some models hint at either Australia or parts of Central Asia.
