Re: Astronomy and Space
That surely raises some questions about the Soyuz leak not really being due to a micrometeoroid hit.

At the time of the Soyuz leak, Anatoly Zak tweeted
In Russian space industry, the excuse "a meteor caused my spacecraft failure" (in this case, the Soyuz coolant leak) is one step away from "my dog eat my homework"...

Last night I got some images of the comet as it went past Mars (horribly overexposed, but otherwise the comet wasn't visible)
ETA
Not literally "past Mars", of course - it was about 66 million km from Earth, and 180 million km from Mars

My avatar was a scientific result that was later found to be 'mistaken' - I rarely claim to be 100% correct
ETA 5/8/20: I've been advised that the result was correct, it was the initial interpretation that needed to be withdrawn
Meta? I'd say so!

Re: Astronomy and Space
Black holes ‘might as well contain dark energy that drive expansion of universe’ what with us not understand either of those things so they must be connected.
(dark energy was invented to explain the apparent acceleration in the expansion of the universe based on supernova brightness vs. redshifts)

having that swing is a necessary but not sufficient condition for it meaning a thing

I see there are widespread reports of Auroral displays visible as far South as Cornwall last night. Got to be worth popping outside tonight to see if they continue.

A newly discovered form of salty ice may be the cause of the red cracks on Europa.

Test launch of the Terran 1 rocket in about 30 minutes (planned for 18:20 GMT).
First launch of a 3D printed rocket.
According to an article I read 3D printing the engines allows them to reduce the number of engine components by 99%.
If successful it'll beat SpaceX's Starship rocket to being the first Methane powered rocket to achieve orbit.
No Payload this time.

A bit churlish
Re: Astronomy and Space
In fact T-20 exactly. It’s on hold. Ah well, this is the “fun” of watching live rocket launches.

Re: Astronomy and Space
Clock running again - currently at 34 minutes - though there will probably be some holds planned
