I’m curious :wiill this be a last Delta IV Heavy Launch?
I’m curious too Aaron especially with the delay of the Vulcan.
This would be the last launch of the Delta IV Heavy from Vandenberg, As well as the last launch of a Delta rocket out of California. The last two flights will fly out of Cape Canaveral in Florida.
Yes good question folks ?, a Heavy vehicle like this you would think NASA would want if they have plans for the ‘Gateway” space station around the moon in the future . More ‘Heavy” lifting vehicles for their payloads the better to choose from .?
I thought the launch postponed on Aug 1st? Someone please confirm the correct launch date?
Launches are not usually scheduled out more than a week or two out. Dates change often. Keep checking back for upates.
Thank you for the info. Will definitely keep checking!
Does anyone know what is the exact launching date and time?
Will this be the last delta rocket launch from California?
