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

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.

In fact T-20 exactly. It’s on hold. Ah well, this is the “fun” of watching live rocket launches.

Clock running again - currently at 34 minutes - though there will probably be some holds planned

One of colleagues is there for the launch, because they helped build the Submillimeter Wave Instrument on it.Brightonian wrote: ↑Fri Apr 14, 2023 9:54 pmSloth just wanted to see the world*

Re: Astronomy and Space
Short of starting it's own thread, this seems the best place for talking about eclipses.
Is anyone else going to see the eclipse today? I'm in Perth, so only getting ~77% of the total eclipse, but at least I'll actually see the eclipse (unlike the 1999 total eclipse I "saw" in Cornwall which was too cloudy to actually see the sun!)

Re: Astronomy and Space
A relatively rare one, as it was a hybrid eclipse, which changed from an annular eclipse to a total eclipse and back again.
Here's a neat view from a weather satellite

Re: Astronomy and Space
I saw some solar observing instrumentation yesterday that will fly during the next eclipse, looking out the window of a plane, to image and do spectroscopy of the corona.

Rapid Unscheduled Disassembly Event. Or RUDE.
