Hi everyone
Please find this month’s news, starcharts and as always a few of this month’s best research items.
You will be pleased to know the satellite Collison didn’t happen it sure was a nice day so I went out and took a few photos, and I have attached one taken around 2pm at the predicted time of re entery over wellington. There are two really interesting articles to read on the subject. The story behind Donald J. Kessler was very interesting and something I had never read about before.
Again Andrew has a range of interesting updates for us too including looking at Bennu and the sample collection a mission I know he’s been following closely.
If your looking for a full update on the Venus news I have managed over the last month to collect up all the bits of research on the phosphine discovery but top of the list are suggestions that the measurement was an error. Either way a new mission back to Venus is needed to study the clouds and map the surface in detail.
Remember it’s the Astrophotography camp in November and I’m hoping to make it along for one night.
Thanks Edwin
