What does a the business end of a rocket capable of generating 12 million pounds of thrust look like? Something like this.

Astra test launch to orbit soon. Countdown is currently on hold. T-7 minutes and counting.


Sideways again, or straight up this time?

It always boggled my mind that all those valves and pipework are seemingly exposed to the heat, and eventual vacuum, and not contained in any sort of isolating shroud.

The joy of thermodynamics and the cooling properties of their contents. Boiler tubes in power stations are exposed to external temperatures far in excess of their strength but the steam flowing through them cools them down even as it is being heated. It's like the engine bells on the rocket, little pipes inside cool the bell whilst pre-heating the propellants. Clever stuff.

Shroud will be installed, Engine bells are liquid cooled and also heat generally goes down rather than up (mostly)

Planet 9 just outside the edge of our solar system most likely, new data. Quite cool actually. Our solar system is quite unique in that it has no super earth whereas other solar systems detected in the galaxy have super earth candidates. So is this outside body our super earth, or an extra solar planet that hitched a ride in the Sun's orbit path long ago?

Dr Jill Tarter features on this week's Event Horizon. John asks an interesting question that is often talked about online about alien life out there ignoring uss if they are intelligent because we would be like ants. He states that we ourselves are scientifically interested in ants, Nat Geo do docus on them, online communities are fascinated by the,... So why wouldn't a scientific alien community be similar assuming they are intelligent?


Can't wait for James Webb to go live and start seeing what we have never been able to see before and hopefully detect exo planets that contain signatures that almost certainly could mean life exists (well more likely once existed) there

Personally I think the possibility is there that our known cosmos is teeming with life. Looking at tardigrades on earth I even think the possibility of micro bacterial life that exists in space itself is even possible.

But the resounding utter facts to date is there is not a single thing. There is a lot of hope, a lot of want, a lot of belief.
But would it not make sense if it is true to put species so far apart they can barely see each other let alone ever meet each other.

If there is an alien race or races out there then they will be busy with their own anthills and their own bacteria in thermal vents etc. They also may have telescopes but probably and hopefully perhaps, are forever restricted by sheer scale and distance they will never have a chance to visit.

Even if like us we are already looking at the real possibility of exploring our solar system in the next 100 years.

Wright brothers flew in 1903
Perhaps 2103 will see manned Jupiter missions from established Lunar and Mars bases.

But the ask to find a neighbour.
The hubble Deep field image was astounding and the numbers are so large that almost surely yes there must be another race out there with car insurance, bills, mortgages, and kids who are dicks!

But the distance and scale is so vast so enormous. It stops us from fighting and messing up the beauty of it all.

Is probably my fav space alien contact type movie ever. I love it.

Although I do like a good alien invasion film or game. :D X Com!

Personally favour the idea that we are simply amongst the first to emerge, in the grand scheme of things we are still in very early days of this universe.

Probably some simple life forms out there but the chances for advanced life to emerge and thrive let alone survive for any real length of time are incredibly small. The higher density, more central, regions of most galaxies aren't particularly favourable places for life the more likely places for life to emerge and survive are the lower density regions on the edges of galaxies so the potential candidates for life are likely far lower than it would appear at first.

Falcon 9 to launch NASA's IXPE in 20 minutes

Oh thanks for the heads up. Forgot it was even happening.
