Space Exploration,astronomy & Cosmology

Ah Mars my favourite planet, Olympus Mons is impressive for sure. Mars is smaller than Earth yet has the biggest mountain, just imagine that on our planet, would be an incredible sight.

Might post a bit more to this thread later this month as SpaceX prepares for their first orbital test of their Starship/Super Heavy rocket, this could be some sight to behold. It will certainly be the biggest most powerful rocket in history.

 

The sheer cliff walls, which must be a good five miles high, intrigue me. Where is the material that fell away?

Usually this forms an angular deposit at the bottom, like here in the Blue Mountains of NSW, where the cliff fall is now covered in vegetation.

 

Clearest evidence yet that the Mars mountain photo was fake. Good work.

 

Or Australia is fake?

 

Interesting theory.

I wondered if the intense desiccation simply speeds up the process by which the fallen material is dispersed. However, one explanation I have read is that the pictures are processed and have a large vertical exaggeration. The cliffs are not so steep in reality.

 

I've stood on the top of those cliffs. They felt real to me.

Mind you, who's to say that I am not fake?

 

Yes, you could be one of a number of accounts run by this person.

 

Following on from my earlier post about Starship, here is a video of the 31 (out of 33) engine static fire they did with their super heavy booster, the last major milestone before they conduct the first orbital launch attempt, this month hopefully. Important to note they only used 50% of the raptor engine thrust for this test, so seeing them go to 90/100% at launch will be a step up.

 

Seeing Mars was, possibly, at least 1/3 ocean it would have had a 'Sea level'. Because it's so small (compared to Terra) its metal core cooled very early on its formation - thus it lost any magnetic field 'locking' any appreciable atmosphere in place.

 

I believe it is still going, one a month at a stupid late hour last I saw.

 

Not me. Sorry.

 

Not even this? You heartless *******.

 

Let’s face it, he was never going to learn an instrument with black keys.

 

Enough of your critical race theory.

 

Stuboy , how far do you think technology is to make a fuel driven engine made from hydrogen and other elements from the environment as claimed by Musk as way of refuelling on Mars or other planets ?

 

I live round the corner to his old house. Locals said it was called " Farthings" per the gate name but that has now been corrected to how it should have read "Far Things". After he died, we had a tour round it as we knew the people who bought it - from Brian May of Queen who actually bought it from Sir Patrick to help him out financially. It reflected his personality massively - having nooks and crannies and stuff everywhere. He also had cats which were not allowed out so were quite "significant". A few years ago it had a blue plaque placed in his memory. His observatory went to a local planetarium but a lovely sundial in his garden has been beautifully restored.

 

Sting! Tis you. Welcome back.

 

Thank you - and sydney - I have posted a short explanation on the wildlife thread,

 

So hard to pick a favourite planet . At the moment seeing Venus and Jupiter almost holding hands in the evening sky is lovely - and Jupiter has always been a favourite of mine due to the great red spot - so reminiscent of my teen years. How can anyone not love Saturn and its rings and as a supporter of the underdog Pluto remains a planet for me. Mars is always good to see with its red tinge. I might cop out though and opt for a fictional planet Magrathea as Hitchhikers' Guide has always been a favourite read of mine

 

Stuboy is waiting for the poo driven engine for his voyage to Uranus.

 

I also love the equinoxes and solstices - Spring approaching

That’s impressive Skyla . Congrats

 

I’m impressed. I guessed that must be your line of work from our discussion of ‘a yard of pace.’

 

That sounds like serious software. No pop-up paperclips saying "I see you're trying to send a rocket into space."
