how fast do we have to go if Earth had no atmosphere?
i'm wondering why don't they send a small, but extremely fast projectile in front of the rocket, which heats and expands the air in front which reduces most of the friction? (maybe like a railgun?)
does that not reduce the cost?
or am i being really stupid?
