Another overdue post that I just got pictures for today: the SIP cage. Juan designed this cage, which lives at the base of Spider, to hold NASA’s SIP (Standard Instrument Package?), and also to support the reaction wheel.
When these photos were taken (almost a month ago) many parts were just tack welded. Now, welding is nearly complete. There will also be four machined parts at the bottom corners to connect to the gondola via carbon fiber tubes.
