ISRO won't fail - they have had every launch be successful.
But yes those that are happy to wait will just have to pay $1 plus but they will still make money.
150 customers paying $500k per year is $75m with 1st cluster . ASX:EOS has $150m revenue and market cap of $900m. So 6 times revenue would make KSS $300m market cap. Then second cluster equals double revenue - which means $600m market cap.
