Test flights to the International Space Station,operated with private sector partners,could start in the first part of 2020.After that,the next big milestone is we want to demonstrate the space launch system,which is a large, heavy lift booster.It's really a rather gigantic rocket to carry us back to the moon, and we're hoping to have that demonstrate itself in 2021. And then we're looking at sending an unmanned mission around the Earth to demonstrate all the parts and components of the lunar return. And then we're going to send humans around the moon. And then we're going to land on the moon. And that's our immediate goal through 2024.
