It's a really important launch, because it's the 1st time a prototype of a vehicle which could someday carry humans is being launched since 2011.
The prototype can't carry humans, has no seats, no instrument panel, & has never been photographed on the inside, but we're told it simulates the requirements of a crewed vehicle, if it's ever funded.
It took 10 years to build this one. There isn't enough money to launch another one for 4 more years. Humans are going to ride Dragon long before Orion ever takes them anywhere.
It's being launched on your favorite rocket, the one you saw in person twice, carrying She Jehovah's payloads. The fact that it takes the largest rocket in the world to launch a tiny capsule shows how much more energy it takes to put a spaceship around the moon than the nominal mission to low Earth orbit. It's been 40 years since such a large rocket for such a small capsule was part of the human experience.
The manned version will be partly made in Europe, by trading investments in the space station from the 1980's for services today for which there was no money. The space station has proven an invaluable bank account for services NASA couldn't possibly afford today.
The rounded cover looked like something from the old west, when it was 1st unveiled 10 years ago. It turned out to not be a stylized artist rendition, but the actual shape.
