Seriously impressive engineering going on there. They are getting stuff done using real skills

I do hope they find more lithium.

Very impressive tech but a complete waste of money and resources.
Musk, Bezos et al seem to following the plot of Ben Elton's dystopian novel "Stark" where the rich realise the Earth is screwed, mainly by their actions, so build spacecraft to escape and screw up somewhere else

I think we need is this guy to add some common sense to all this.

Sorry, but I don't think it's reasonable to include Musk in the group labelled "Bezos et al". Certainly in terms of SpaceX, the record of achievement is really impressive. SpaceX is doing what very few Nation states can do. The European Space Agency has closed down the Ariane V production line before it's even frozen the design of Ariane VI, let alone started production. I suspect thay could end up using SpaceX for most of their launches for a significant period of time.

Agreed. Spacex is a commercial company. They launch satellites that deliver value to someone. They use less materials and lift more than anyone else.
It's not a vain glorious toy, but a well run business that's doing more than anyone else in the industry.

Its the populating Mars bit I was referring to. I get the satellite/payload launch bit, that makes sense.
If I could choose which 100 people went on the x number of years journey via SpaceX to Mars with no guarantee of return, then that would be a different matter

Problem is if they have internet access on board they could still post hereIf I could choose which 100 people went on the x number of years journey via SpaceX to Mars with no guarantee of return, then that would be a different matter

sounds a bit like sending prisoners to Australia a few years ago

I've been waiting for years for this thing to launch...I'm delaying my drive today just so I can watch it.
If this works I think this will reduce the cost of accessing space forever!

But, without the rocket there wouldn't be a satellite to tell her that the climate is changing!

As rockets go, it's relatively benign; only puts out water and CO2. The nastier ones use the big solid propellant boosters which pump out aluminium oxide and hydrogen chloride, which will turn to hydrochloric acid.Where does Greata stand on all the pollution the rocket put's out ?...

But, but, that's what they put in beer and cider, and welding gas, isn't it? So more of that is good, right?

Emissions calculation for Starship:
- each starship burns approx. 4600 tons of methalox fuel (depending on mission)
- the mixture ratio of the propellent is 78% O2 and 22% CH4
- that means that each 100 tons of methalox results in 53.6 tons of CO2 and 2.5 tons of CH4 (unburnt fuel) plus water vapour and some CO too.
- generally in the climate science it is accepted that one ton of CH4 is equivalent to 25 tons of CO2
- overall, each 100 tons of propellent will produce 116 tons of CO2-equivalent emissions
- a single launch of 4600 tons propellent will result in 5.34 kT CO2 emissions
if they captured the methane from cow burps, farts or other naturally occurring sources then you could say this is helping reduce greenhouse gases by burning methane that is 25 times worse than CO2, but they don't. The methane is almost certainly from fossile fuels and wouldn't be produced if the demand wasn't there but the potential is there to be "green"

O.K. and then what are they going to do once they have accessed space. A bit like climbing Everest. "Well we made it so I suppose we had better head back down then."
