Launching the same rocket to orbit twice in 24 hours has never been done before. But Elon Musk says the newest version of his Falcon 9 rocket will accomplish the feat in 2019.

“This is a ridiculously hard thing that has taken us 16 years of extreme effort and many, many iterations,” the serial entrepreneur told reporters, after warning them “we’re definitely going to stay on space, don’t even try.” SpaceX is debuting the new rocket today with the launch of Bangladesh’s first satellite.
