Re: Elon Musk's Starlink satellites are on track to outnumber the number of stars in the sky
A quote from the article will give you an idea of the reliability of the source:- "In its filings, SpaceX said the additional 30,000 satellites would operate in low Earth orbit at altitudes ranging from 1,076 feet to 1,922 feet." The satellites would be colliding with hills and mountains a...

"The Webb telescope is the most powerful in the world"

Re: New Moon: 21 Mar 2023
"It's interesting that the moon is 1/400th the diameter of the sun but also 400 times farther away".
No, the Moon is 400 times nearer.

Re: Bluewalker 3
Quote from above " It could become brighter than the planet Venus, outshining everything in the night sky except the Moon." I saw it last night (Sept. 22) - it was magnitude +6.4 And Skipper Billy's image is NOT SW3, his object is in a polar orbit - SW3 is in an orbit inclined at 53.2 degr...

Re: Deorbiting the ISS
Russia intends to build its own space station, so there will be 3 stations to observe in a few years time.
All going around the round-about in the same direction.

Re: Struggling with Supermoons
"I'd be interested to know if anyone here could step outside and say with confidence that they can see the difference between this month's full Moon and last month's."
Last month's was only 100 miles further away than this month's - so it too was the dreaded "Supermoon".

Re: A Shetland’s spaceport
Scotland is best because its northerly aspect means launches pass over the sea, and not over inhabited areas.
Sun-synchronous orbits (inclined at near 98°) are valuable for Earth surveying missions.

Re: Heads up
Prediction fulfilled. Not able to give a direction, as at the time of my message, Landsat 9 was still on the launch pad. However, the launch (at 18.12 U.T.) went according to plan and the resulting phenomenon was the Centaur rocket performing a de-orbit burn to remove itself from orbit and thus help...
