Reminiscent of a chrome-plated exhaust manifold from a 20th century vehicle.
The Teslarati article SpaceX’s Falcon Heavy flies a complex mission for the Air Force in launch video discusses the upcoming third Falcon Heavy mission STP-2 and links to the SpaceX (unlisted?) video STP-2 Animation.
Prior to propulsive passivation (What is "propulsive passivation" and why will the SpaceX STP-2 mission do it?) the strangely-shaped DSX payload is deployed.
Question: Telsarati points out that SpaceX has a special website for this payload: https://www.spacex.com/stp-2 and there is a detailed image there as well as a detailed explanation of experiments. But I don't understand (at least) two things:
- Why is DSX two satellites connected by a ring?
- What are all those tubes on box on the right (image below)?
